Design for a motor casing
|
John R. Morgan |
Oak Park, IL |
Seen on a 1/2 HP induction motor from Sears, model number 315.1952. The maker's prefix of 315 corresponds to Diehl Mfg. Co., "Ryan", and Ryobi. By far the most likely match is Diehl, which was a motor manufacturer active at the time. They were best known for supplying motors for Singer sewing machines. |

Peter M. Roberts |
Gardner, MA |
A spring-loaded central pin in the center of a ratchet driver has a indentation into which the spring ball or detent which holds a socket can retract.
The patent was the basis for SEARS, ROEBUCK & Co.'s quick release feature on CRAFTSMAN ratchets, and the center of protracted litigation between SEARS and the inventor.
