Re: Patent Model of Railroad Truck


The patent documentation may be the excuse for the high price but it is an expired patent and the documentation can be obtained from the US Patent and Trademark Office for the cost of duplicating and shipping if you take the time to search the US patents on line and find the patent number.? I would venture that would be far less than the current asking price on Ebay.

Quite a high asking price for such a crude model. I suppose that the reserve
price may be what it is due to the patent documentation that comes with the

As for this patent being issued "just before WWI", that threw this Canadian for
a loop. The UK, Canada, and Australia (a few citizens of each are on this list)
were involved in WWI from 1914-18.

You can see it here:

Patent applicant is a Mr. Walther Chalfent of Brownsville, PA and the truck
has an unusual double sideframe design (essentially, there are sideframes on
both sides of the wheels. The patent application dates from just before World
War I - 1915-16.

From the side the sideframes look similar to more contemporary trucks, but no
specific features that scream "here is the origins of "XX" truck can be readily
identified from the images with the auction. I'd say most likely this is an
interesting concept that proved unworkable, too costly, or unreliable and
therefore never got beyond the patent/prototype stage.

Thought some of the truck historians on this list would be interested and
perhaps some may know better than I if anything came of this design - or the
patent applicant.
