Abstract

292,606. Desmul, P. C., and Wallez, A. June 23, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Percussive tools.- Air escaping from a pneumatically actuated drill or other tool is diverted by a bell-shaped sleeve 5 mounted between shoulders 3, 4 on the tool. The escape ports 8a for the exhaust air are stated to be inclined rearwardly, but are not so shown in Fig 4. They are covered by a bell-shaped sleeve 9.
