    I've always looked to deal in collectibles that would be attractive to buyers in more than one category. The reason is obvious--more potential customers. In this week's show I'll profile collectibles that I've found in the Brass Armadillo Antique Mall in Denver that appeal to shoppers across several categories. We'll look at Masonic collectibles, a Mickey Mouse clock, animals as subjects, styles as collectible in their own right, and many more. We'll try to get at how much more a cross collectible might be worth given its attractiveness in more than one category. It's all a little subjective, don't you think? But I do think we can make some generalizations. Hope you can join us this Sunday evening, May 8, 2016, at the usual time: 5PM PDT, 6PM MDT, 7PM CDT, 8PM EDT. Gary

    I found some very interesting bargains and very interesting unusual vintage & antique pieces at the Brass Armadillo Antique Mall in Denver yesterday, so I've devoted this week's show to showing you what I found! There's a large Pepsi Cola radio from the '50's, a Miller Brothers 101 Ranch booklet from the '20's, a great grain painted pie safe c. 1850, a 20" x 16" studio photo c. 1870, and many other items. Please join us on Sunday evening, May 1, 2016, at the usual time: 5PM PDT, 6PM MDT, 7PM CDT, 8PM EDT. Some of the questions we'll be trying to answer are: can you have collectible advertising pieces made long after the company doing the advertising has gone out of business? ( is that a trick question?), why does anything "Western" sell for far more than relative comps even those from the old Confederacy?, what's a double camel saddle & who cares?. Hope you can tune in.

    You can't watch even 1 epidode of Antiques Roadshow without learning that anything that has the word "Tiffany" in it, whether Tiffany Studios or Tiffany & Co., has value added just for having been sold at Tiffanys. But what about other retailers? What about department stores like Marshall Field and Liberty of London? What about clothiers like Jacob Reed's & Sons? What about art galleries? Join us on Sunday evening to consider the value that the seller adds to price. We're on at the usual time: 5PM PDT, 6PM MDT, 7PM CDT, 8PM EDT, April 24, 2016. Gary

    '60's is definitely "vintage" now, don't you think? The '80's may never be anything but used and eventually old! But what about the 1970's--is stuff from the '70's now considered vintage? We'll look at examples from several categories--women's clothes, furniture, advertising and try to answer that question in this week's show. If a piece of factory made furniture from 1915 is now technically an antique, is a plastic something from the '70's from Sears now vintage, and possibly worthy of being collected??? Please join us at the usual time this coming Sunday evening, April 17, 2016 and weigh in with your opinion. We're on at 5PM PDT, 6PM MDT, 7PM CDT, 8PM EDT. Gary

    Here is  a Slight history on insulators, pertains mainly to the glass variety, to see a full history please feel free to visit http://www.nia.org/timeline/index.htm where I found the following facts from. May 24, 1844:  Samuel Morse transmitted the first telegraph message over a short telegraph line run along a railroad between Washington, D.C. and Baltimore with the famous words "What hath god wrought!".  Based on advice from Ezra Cornell, the insulators used on this line were made of two flat glass plates surrounding a cloth wrapped wire in slot in the crossarm. April 18, 1846: Royal E. House of New York, NY patent for a telegraph that prints characters to be decoded titled "The Magnetic Letter Printing Telegraph".  The idea was different enough from Morse's design to avoid infringement.  An unusual metal and glass insulator was developed uniquely for the House telegraph.  (US Patent 4,464) July 24, 1846:  Addison Smith of Perrysburg, OH patent for a fire detector and alarm system using telegraph to transmit information.  (US Patent 4,661) April 5, 1848:  Ralph Gray and Robert Hemingray signed a five year lease for a small half-lot on Hammond Street (originally known as  Mayor's Alley from Third to Fourth, between Main and Sycamore) in Cincinnati, Ohio.  They soon began manufacturing glass at this location under the name of Gray & Hemingray Glass Works. February 5, 1850:  James Spratt of Cincinnati, OH patent for a lightning rod insulator design.  This patent was implemented in an early LRI (Lightning Rod Insulator).  (US Patent 7,076) October 14, 1851:  John Yandell of  St. Louis, MO  patent for a glass block insulator.  A good example of this CD 1014 insulator exists in the Smithsonian Institution archives.  (US Patent 8,438) -- [Full Patent Text] March 29, 1859:  Russel Hickok of Fort Edward, NY patent for a glass lightning rod insulator design.  Link for more details! (US Patent 23,373) -- [Full Patent Text] August 5, 1861: The Transcontinental Telegraph, which connected St. Joseph, Missouri and Sacramento, was completed by the Western Union Telegraph Co. and its associates.  In 1869 this line was rerouted to follow the Transcontinental Rail Road July 25, 1865:  This important patent was by Louis Cauvet for the a method of forming internal threads an insulators to allow them to screw onto a threaded pin.  Previous insulators were threadless and held on the pin by friction. Brookfield was the first to license this patent.  (US Patent 48,906) -- [Full Patent Text] December 19, 1871:  Robert Hemingray patent for a technique for molding glass insulators.  This patent was used on a very large variety of insulators.  (US Patent 122,015) -- [Full Patent Text] -- (Additional Patent Image) January 23, 1872:  Chester H. Pond of Cleveland, OH patent for a threaded wooden insulator with a metal cap.  Several excellent examples of these insulators can be found in the Smithsonian archives.  (US Patent 122,961) -- [Full Patent Text] February 6, 1877:  Paul Seiler patent to provide six longitudinal ribs to both strengthen the insulator without adding weight and reduce the contact area with the tie wire.  This patent was implemented in CD 130.2.  (US Patent 187,183) -- [Full Patent Text] January 14, 1879:  James M. Brookfield design patent for the CD 102 "pony" style insulator.  (US Design Patent 10,981) -- [Full Patent Text] September 13, 1881:  Samuel Oakman patent for a process of forming threads on an insulator by plunging a previously formed (and cool) threaded glass cup into the molton glass in the mold.  The glass would cool enough as to not overly distort the threaded cup.  This technique was used by the American Insulator Co. on many of their insulators as well as some unembossed pieces and a CD 134 marked with just the patent.  This is the reason that many of these pieces have poorly defined or somewhat distorted threads, as the glass cup would soften in the molton glass.  (US Patent 247,100) -- [Full Patent Text] May 1, 1883:  Joseph S. Lewis patent for an external thread above the wire groove to allow the insulator to be "screwed in" to a tie wire.  a damaged insulator could also be replaced without undoing the tie wire.  The patent drawing shows the threading to be in the same direction as a normal insulator's internal threads, making one loosen it on the pin to attach the tie wire (Not a desirable function).  Frank Pope's patent later this same year (Dec. 25, 1883) is for virtually the same design, only threaded in the opposite direction.  Both patents appear on the National Insulator "Corkscrew" styles CD 110.5 and 110.6.  (US Patent 276,839) -- [Full Patent Text] August 14, 1883:  Homer Brooke, of Jersey City, NJ patent for an insulator press.  This patent was implemented on a number of Brooke's insulators including CD 120 and 133.1 and it is likely that this is the "patent applied for" on a number of other styles attributed to Homer Brooke including CD 120.2 and CD 125. Thanks to Bob Stahr for providing this data originating from Dick Roller who put together a great reference data base. (US Patent 283,321) -- [Full Patent Text] -- Link to additional Homer Brooke information. October 16, 1883:  Bradley A. Fiske and Samuel D. Mott patent for diamond shaped indentations in the wire groove to reduce electrical contact with the tie wire.  This patent was implemented in both CD 135 and CD 109.  (US Patent 286,801) -- [Full Patent Text] December 25, 1883:  Frank L. Pope patent for external threads opposed to the internal to allow the replacement of a broken insulator without disturbing the tie wire.  This patent was implemented in CD 110.5 and CD 110.6. (US Patent 290,922) -- [Full Patent Text] June 24, 1886:  The pottery & Glassware Reporter was informed by Mr. E. A. Leonard that the Leonard Glass Works of Detroit, Mich., has closed down and may not be reopened August 17, 1886:   John O'Brian of New York, NY patent for a unique insulator design assigned to William Brookfield.   This patent was implemented in the Brookfield CD 119 insulators, although the embossing provides the wrong patent date.   (US Patent 347,635) -- [Full Patent Text] November 23, 1886:  Robert G. Brown of Brooklyn, NY assigned to the E.S.Greeley & Co. patent for an insulator and pin to allow mounting below the crossarm.  This design could double the number of circuits supported by a single crossarm or be used to facilitate wire transposition.  This patent style is known as the "Brown Pony" and was implemented in CD 187 & CD 188 as well as U-81, U-82, U-84 and U-85.  (US Patent 353,120) -- [Full Patent Text] November 8, 1887:  Francis H. Soden and Henry Goehst patent for a strain insulator for electric lights.  This patent was implemented in the CD 1129 glass strain. (US Patent 372,940) -- [Full Patent Text] June 17, 1890:  Samuel Oakmen patent for the ears found on cable insulators - CD 258, CD 259, and CD 260 match closely the patent drawings.  (US Patent 430,296) -- [Full Patent Text] August 19, 1890:  Samuel Oakman for a skirt projection to act as a water stop as well as threading the inside of the inner skirt to increase the leakage distance.  This was implemented in CD 258, CD 259, and CD 260.  (US Patent 434,879) -- [Full Patent Text] December 23, 1890:  Foree Bain patent for grooves inside and outside the insulator surface for the dual purpose of increasing leakage distance.   This has been implemented on CD 144.  This patent was assigned to the Hemingray Glass Company on February 28th, 1901. (US Patent 443,187) -- [Full Patent Text] February 1891:  Pass and Seymour of Syracuse, NY starts making threaded porcelain "wet process" insulators.  The only known existing style they made is U-146, although they also catalogued U-141.  Sometime in 1895 or 1896 they stopped making pintype insulators. May 2, 1893: Ralph G. Hemingray patented drip points.  The intent was to provide a point for moisture to accumulate and more quickly drip off the insulator keeping it dryer.  This date is considered significant as drip points were so widely implemented.  (US Patent 496,652) -- [Full Patent Text] August 29, 1893:  George W. Blackburn of Palmyra, NJ patented an insulator design using a bail clamp to hold the conductor wire.  This patent was implemented in CD 141.6 (US Patent 504,059) -- [Full Patent Text] August 14, 1894:  George H. Winslow of Pittsburgh Pennsylvania patent for a unique series of oil cup insulators for high voltage use.  This patent appears to have been implemented in several rare insulator styles including  CD 180, CD 180.1 and CD 244.  (US Patent 524,659) -- [Full Patent Text] -- (Additional Patent Image). September 25, 1894:  David N. Osyor patent for a pin and insulator combination that was assigned to the Jeffery Mfg. Co.  This was implemented in the CD 185 Mine insulator and porcelain U-89 through U-98B.  (US Patent 526,498) -- [Full Patent Text] 1895: The first underground trolley system in the United States is constructed in Boston, MA.  This system used relatively low voltage DC which required very large copper cables.  The CD 140 "Jumbo" was designed for this line. September 3, 1895:  Danial Rothenberger patent for a unique cable style insulator with a hole through the crown perpendicular to the tie wire.  This patent was implemented in the rare Brookfield CD 268.  (US Patent 545,819) -- [Full Patent Text] February 12, 1896: "China Glass & Lamps" reports the new glass works being erected at Westport, Md., by the Baltimore Glass Mfg. Co., is nearing completion.  Later reports show production started by the end of March making Screw cap ware, fruit jars and electrical supplies. -- Their insulators are marked B.G.M.Co. and are mostly found in purple glass. April 7, 1896:  Hannibal W. Rappleye patent for a bail-clamp tie arrangement to hold the conductor.  This patent was implemented by Brookfield in the rare CD 134.6 (US Patent 557,881) -- [Full Patent Text] September 28, 1897:  Fred Locke patent for a power insulator with an oblong shape and side troughs to direct water away from splashing on the crossarm.  This patent was implemented in the U-937 insulators that Locke had Imperial Porcelain make for use on the Niagara to Buffalo power line.  (US Patent 590,806) -- [Full Patent Text] March 8, 1898:  John W. Boch patent for a three piece porcelain power insulator where the three shells were fused together with extra glaze.  This was implemented in the Classic Thomas styles U-928 and U-928A.  (US Patent 600,475) -- [Full Patent Text] June 7, 1898:  Ralph D. Mershon of Colorado patent covering a power insulator design with a far extended inner petticoat and ridges on the top skirt to direct water off the insulator.  This patent was implemented in CD 288 and CD 298 as well as U-938, U-944 and U-945.  (US Patent 605,256) -- [Full Patent Text] September 3, 1898: A British patent by Daniel Sinclair and William Aitken both of Oxford Court, London patent for a two part dry spot insulator implemented in U-1925,U-1929, and U-1929A. (UK Patent 25,816 of 1897) -- [Full Patent Text] September 19, 1899:  Frederick H. Withycombe of Montreal, Canada patent  for a various ridge designs on the outside of an insulator to provide a "cushion" to damage from projectiles (ie: thrown rocks).  This first patent illustrates horizontal ridges.  He released four very similar Letters Patents and two design patents for virtually the same ideas.    Horizontal ridges are found on a number of Canadian CD 143's.  (US Patent 633,173) -- [Full Patent Text] 1900:  An eight mile elevated section of Boston's transit system was constructed.  Heavy DC cables were required and this line used CD 267 and CD 267.5 insulators without tie wires.  The weight of the cable was sufficient to hold it in place below  the tracks. June 10, 1902:  Vernon G. Converse patent for a stacking insulator.  This patent was implemented in the amazing glass insulator comprising CD 317.8, two CD 313 sleeves, and one CD 313.1 sleeve.  (US Patent 701,847) -- [Full Patent Text] April 7, 1903:  Ferdinand W.

Locke patent for the design of the M-2795 insulator.  (US Patent 728,805) -- [Full Patent Text] November 17, 1903:  Edward F. Schoethaler of Longbranch, NJ patent for a unique insulator design.  The drawings look very similar to the recently found "Spaceman" CD - The intent was to provide extra protection from a wire coming undone which may indicate that this idea influenced  the rare CD 139 Brookfield "Combination Safety" insulator.  (US Patent 744,631) -- [Full Patent Text] April 26, 1904: Scott Cutter patents the unusual CD 1038 glass Cutter tree insulator. (US Patent 758,175) -- [Full Patent Text] March 24, 1908:  Leonard W.

Eveleth of Schenectady, NY patent for a porcelain power insulators with skirt grooves to allow pieces to break off if hit by a projectile preventing the loss of the whole insulator.  This patent was implemented in the rare M-2202 and M-2202A porcelain power insulators.  (US Patent 917,031) -- [Full Patent Text] March 19, 1910: The Hemingray Glass Company received Trade Mark No. 79,096: “HEMINGRAY” for use on ‘electric, telegraph, telephone, cable, street-railway, and floor insulators and break-knobs of glass.’ It was noted that the trade mark had been in use for 10 years.  Link for additional Hemingray information. January 16, 1912:  John Hilliard Jr. and Charles E. Parsons of Glens Falls, NY patent for a unique rigid suspension insulator made with multiple insulating shells mounted on a rod with two metal ends.  This is quite likely the patent for the recently found suspension insulators made from five CD 314 Hemingray shells.  (US Patent 1,015,229) -- [Full Patent Text] August 11, 1914:  Benjiman S. Purkey of Tacoma, WA patent for a twist lock "No Tie" porcelain insulator.  This patent is implemented in U-186.  Although unmarked, the recently discovered CD 207.5 may also have been made to this patent.  (US Patent 1,107,111) -- [Full Patent Text] Sept. 18, 1917:  Louis Fort of Jersey City, N.J. patent for a porcelain and metal two piece clamp insulator for street light drops.  These unusual insulators were made in brown porcelain with a cast metal clamp and mounting. (US Patent 1,240,330) -- [Full Patent Text] February 26, 1929:  Rufus Gould of New York, NY patent for a dry spot insulator assigned to the Postal Telegraph Co.  This patent was implemented in Whitall Tatum CD 182 and porcelain styles U-173, U-174, and U-175.  It called for a large inner skirt gap where the drop wire could be potted to keep wetness out.  (US Patent 1,703,853) -- [Full Patent Text] April 9, 1929:  Leon T. Wilson of East Orange, NJ assigned to A.T.& T.

February 5, 1850:  James Spratt of Cincinnati, OH patent for a lightning rod insulator design.  This patent was implemented in an early LRI (Lightning Rod Insulator).  (US Patent 7,076) October 14, 1851:  John Yandell of  St. Louis, MO  patent for a glass block insulator.  A good example of this CD 1014 insulator exists in the Smithsonian Institution archives.  (US Patent 8,438) -- [Full Patent Text] March 29, 1859:  Russel Hickok of Fort Edward, NY patent for a glass lightning rod insulator design.  Link for more details! (US Patent 23,373) -- [Full Patent Text] August 5, 1861: The Transcontinental Telegraph, which connected St. Joseph, Missouri and Sacramento, was completed by the Western Union Telegraph Co. and its associates.  In 1869 this line was rerouted to follow the Transcontinental Rail Road July 25, 1865:  This important patent was by Louis Cauvet for the a method of forming internal threads an insulators to allow them to screw onto a threaded pin.  Previous insulators were threadless and held on the pin by friction. Brookfield was the first to license this patent.  (US Patent 48,906) -- [Full Patent Text] December 19, 1871:  Robert Hemingray patent for a technique for molding glass insulators.  This patent was used on a very large variety of insulators.  (US Patent 122,015) -- [Full Patent Text] -- (Additional Patent Image) January 23, 1872:  Chester H.

Lewis patent for an external thread above the wire groove to allow the insulator to be "screwed in" to a tie wire.  a damaged insulator could also be replaced without undoing the tie wire.  The patent drawing shows the threading to be in the same direction as a normal insulator's internal threads, making one loosen it on the pin to attach the tie wire (Not a desirable function).  Frank Pope's patent later this same year (Dec. 25, 1883) is for virtually the same design, only threaded in the opposite direction.  Both patents appear on the National Insulator "Corkscrew" styles CD 110.5 and 110.6.  (US Patent 276,839) -- [Full Patent Text] August 14, 1883:  Homer Brooke, of Jersey City, NJ patent for an insulator press.  This patent was implemented on a number of Brooke's insulators including CD 120 and 133.1 and it is likely that this is the "patent applied for" on a number of other styles attributed to Homer Brooke including CD 120.2 and CD 125. Thanks to Bob Stahr for providing this data originating from Dick Roller who put together a great reference data base. (US Patent 283,321) -- [Full Patent Text] -- Link to additional Homer Brooke information. October 16, 1883:  Bradley A. Fiske and Samuel D.

    There is a frenzy going on amongst the Denver Brass Armadillo Antique Mall venders this week....and as well there should be!   We had more great success with the Classified Listing Program within the Mall.  It brought in some really great sales and got multiple venders excited about getting their own items posted and up on the internet.   Back in May of 2012 a couple of venders came to me and asked me to post an item that they had stored in one of our back rooms.  The item was too large for them to display in their space in the Mall, but depite its size and "unique vibe", we knew that the item would make the right buyer a happy camper....if we could only find them, or better yet, help them find us!     This 1920's antique medical exam table is oak with all the fixings:  2 sets of stir-ups, the original leather, height & foot adjustments,  blood pan and 4 pass through drawers.   The item was originally listed on May 2, 2012 and reposted approximately every 60 days with no success in finding a buyer for this unique item. But just after reposting it at the end of September, a couple of gentlemen came into the Mall and asked us to pull the table out of storage.  They looked it over and happily took it home with them on Wednesday of this last week.    As if this weren't already a great enough story.....    Shortly after I was asked to post the medical exam table, the same set of venders asked if I could come out to their shop and storage unit and list some additional  items that they wanted to sell.  Due to the collectability, rarity & value of the items, I happily obliged.  Again, I continued to repost the items as they expired and just this last Tuesday, after reposting it just two days before, we received a call from an interested buyer for this beautiful quarter sawn oak Early Murphy Bed with desk and beveled mirror.     People, I have seen this happen time and time again.  I'll list an item and nothing happens, but then I'll repost it and we make a connection.  It's all a matter of finding that one person and what better way to do that than by listing your items and being persistent.        Amie Martin Social Networking Coordinator Denver Brass Armadillo Antique Mall

    This week's show is entitled, "The Importance of Provenance," but maybe it would be better to say "The Joy of Provenance." If you like antiques, you probably enjoy history, and what could be more interesting than researching your own possessions to establish a line of ownership thru the years? So, I've taken a few pieces that I own and some that I see for sale in the Mall, and show how I was or was not able to establish ownership back to when the pieces were made. In every case the attempt was worth the effort, even if the chain is broken in some places. I do this more for myself than for any future owner, but I do think that buyers enjoy knowing the most they can about whatever they buy. I did a show a few years ago entitled, "People Buy Stories," which is in the Videos section, and in it I give a few examples of how histories can give value to objects. Hope you can join us at the usual time on Sunday evening, 5PM PDT, 6PM MDT, 7PM CDT, 8PM EDT for this week's shows. Gary
