Abstract

139,786. Liberty Tool Co., (Assignees of Diffendall, W. H.). March 12, 1917, [Convention date]. Addition to 125,958. Riveting.-A stay-bolt riveting attachment for fluid-pressure hammers, as in the parent Specification, comprises a hollow casing 1 to be slipped on to the end of the hammer and having a spring-supported set 2. The spring 4 is conical to avoid breakage if excessively compressed, and engages a hardenedsteel bush 5 and a flange 2<b> on the set 2, upward movement of which is prevented by a screwed ring 6 locked by a spring 3. The stem 2a enters the bore of the hammer and receives the blows, while the body of the hammer enters the sleeve and engages the rubber cushion 7, air escaping through holes 1<g>. The flange 1<a> engages the bolt head and guides the hammer as it is moved about in riveting.
