Steam engine Patentee: John Urpeth Rastrick - Bridgnorth, county Salop (Shropshire) England Granted:1814-04-01

The inventor was one of the first steam locomotive builders, working with Richard Trevithick. At the time this patent was granted, Rastrick was a partner in Hazledean & Rastrick in Bridgnorth, Shropshire, but the partners had a troubled working relationship and the business was dissolved with a year or two. So far as we can determine, Hazledean & Rastrick never manufactured this engine. Rastrick was quite secretive, keeping his notes in code, and the patent specification apparently tried to avoid revealing enough to allow someone else to build his engine. A search has failed to turn up a patent drawing or specification. In any event, Foster Rastrick & Co. was formed a few years later to manufacture Rastrick's engines. In 1829 a famous early locomotive engine, the Sturbridge Lion, was produced, and was shipped to Honesdale, Pennsylvania. A trial run—on wooden tracks with wrought iron running surfaces attached by screws—was successful but it was recognized that the wooden tracks weren't suitable. The locomotive never saw active use and it was eventually dismantled. In 1889, the engine was partially reconstructed with as many original parts as could be found, and was on display for many years at the Smithsonian Institution. A full-scale replica is on exhibit at the Honesdale Museum. Meanwhile, another engine produced by Foster Rastrick in 1829, the Agenoria, stayed in England and was used by the Shutt End Railway for about thirty years.

Release Mechanism for Articulated Lever Wrenches Patentee: Stephen M. Kash - Elkhart IN Granted:1949-11-29

The lock release operates by pulling toward the "fixed handle," with a spring to keep it normally nested in the lever handle. The jaws on a known example do not fully close, but that may be due to wear over decades of use. Kash Industries advertised the K-VISE in 1948. George D. Haight and Carl Hoppe - patent attorneys

Combined nippers and horseshoe nail clincher.

The specifications do mention an optional spring to help open the jaws. Munn & Co. attorneys Warren was offering to sell the patent rights in early 1864 issues of SCIENTIFIC AMERICAN.

Gage Patentee: Judson Switzer - Portland OR Granted:1920-06-22

Judson Switzer is back with an improvement to his 1917 butt gage patent (1,223,531). The tool is substantially the same, but instead of lockingthe various marking members in place with set screws this gage provides thumb-wheels for adjustment. I'm not sure the improvement here is actually a step up. While the new adjustment feature is certainly more clever and gadgety, it seems like it would be very easy to accidentally knock the points out of alignment.
