Abstract

407,481. Grinding valves. ALLEN, C., The Stores, Woodcote, Oxfordshire. Dec. 14, 1932, No. 35379. [Class 60.] Grinding interfitting parts together.-A portable device for grinding valves in their seats comprises a rotatable member 17 for engaging the valve, a crank 12 connected thereto and a reciprocating or rotary driving member 11 connected to the crank 12 by a casing 5 containing a compression spring 13, Fig. 2. The member 11 may be moved by hand or by a motor within the casing 1. Either or both of the members 11, 12 may comprise variable throw cranks. The member 17 has its blade 22 removable so that a valve having holes may be engaged by pins 25, and is connected to its shaft through a spring-opened clutch 18 or a magnetic clutch which may be used for lifting the valve and may be energized only when the electric motor is running.
