Original US Patent Model 1924 Patent #1,480,885 Railroad Track Safety Bolt Lock

Description

Original US Patent Model 1/15/1924
Patent #1,480,885
Railroad Safety Bolt Lock
This is the original patent model submitted to the US Patent Office on April 15, 1922 and renewed Dec. 6, 1923.
This model is unusual because it is from the early 20
th
century. The Patent Office stopped requiring models for patent applications about 1880. They sold all the models in 1926 so this model was never submitted to the Patent Office.  I bought it with a note attached showing the patent number. The inventor submitted for a patent 4/1922, renewed it 12/23 and the patent was issued 1/1924 so the process lasted 21 months.  Because of the era submitted, there are no original patent tags.
This model consists a piece of railroad track made of wood with the painted steel bolt, nut and safety lock attached. The black paint is rubbed off the edges of the track.
5” long x 3 ¾” wide x 4” tall
Inventor’s Name and Location:
Ludwig Grossman of Camden, NJ

A Brief History of Patent Models
(Underappreciated National Treasures)
1790 - The US Patent Office is created. Models were required to be submitted but no numbers were assigned.  Models were supposed to be a working miniature, no larger than 12" cube; however, that size limit was not enforced.
1836 - The first of two major fires occurred. The fire destroyed all 7,000 patent models.  The patent office started assigning numbers to patents.
1840s-1880s - The Patent Office in Washington, DC displayed thousands of models and attracted hundreds of thousands of visitors who viewed the models as a popular pastime.
1877 - A second major fire burned about 87,000 patent models.  The ones salvaged from the fire were given a patent tag with a note that they were removed from the fire.
1880 - The Patent Office stopped requiring a model to be submitted but some inventors were still submitting models as late as 1920s.
1908 - The Patent Office donated about 1,000 patent models to the Smithsonian Museum
1926 - The Patent Office sold the remaining models to Henry Wellcome (founder of Burroughs Wellcome pharmaceutical company).
1936 - After suffering financial losses during the depression, Mr. Wellcome died in 1936.  The models were sold and then re-sold to a group of investors for ,000. This group formed the American Patent Models, Inc. located in Rockefeller Center, NY.  They inserted the patent tags in specially designed sleeves with a black border. They added a lead seal to the wire holding the tag.  The group tried to display and sell models but went bankrupt.
1941 - Mr. Rundle Gilbert bought all the models for ,000. There were 30-40 truckloads of boxes and about 100,000 models.  He outbid another person who planned to sell the models for scrap.
1940s-1970s - Mr. Gilbert traveled throughout the US displaying and selling models at department stores and flea markets.  He sold thousands of models at a series of auctions in the 1970s in Garrison, NY.  He lost about 15,000 in a fire.  Many other models suffered damage from water and being improperly stored.
1979 - Cliff Peterson, an engineer from California, bought the remaining models, about 35,000. He donated about 30,000 models and cash to a newly formed organization, The US Patent Model Foundation, with the plan for them to start a museum. The organization starting selling the models.  A lawsuit failed to return ownership of the models to Mr. Peterson. The certificates they issued identify these models.  I don't consider the certificates to add value but they are useful to trace the provenance of these models.
c2000 - Mr. Peterson sold about 4,000 models to Alan Rothchild who restored many to original condition and wrote a book featuring some great models.
2015 - Mr. & Mrs. Rothchild donated their collection to the Hagley Museum in Delaware where they are being cataloged and added to the Hagley's existing collection.  The Hagley has many models pictured and described on their excellent website.
2021- Patent models continue to be underappreciated. They are one of the few antiques that can be positively dated
and
each one is one of a kind. Many antiques are mislabeled ?unique? but each patent model is truly unique.
Mr. Gilbert bought about 100,000 models.  There are far less than 50,000 in the world if you subtract the 15,000 models destroyed in his fire; ones damaged by rain and in warehouse collapses; ones in the collections mentioned above (35,000) and ones that have been lost or separated from their tags.
