No. 189,411. Patented April 10, 1877.
UNITED STATES PATENT QFFIGE ENDS WRIGHT, OF DENMARK, IOWA.
IMPROVEMENT IN RlVETlNG-HAMMERS.
apecification forming part of Letters Patent No. l 89,411, dated April 10,1877; application filed September 20, 1876.
To all whom it may concern:
Be it known that I, Enos WRIGHT, of Denmark, county of Lee, State of Iowa, have invented a certain new and useful Improvement in Riveting-Hammers, of which the following is a full and clear description, reference being made to the accompanying drawing.
My invention consists in an improved riveting-hammer, having a face of thei'orm of a cross, produced by the intersection of two rounded panes.
The advantages of this kind of hammer are, that it expands the rivet both ways at the same time, is less liable to cripple the rivet, and accomplishes the Work much faster and better.
What I claim is- The improved cross-paned hammer, herein described and shown.
EN OS WRIGHT. Witnesses:
