PATENT OFFICE;
AND roummx: comrnnr, JERSEY.
To all whom it may concern:
. Be it known that I, Wrmui w residing-at Berwick, Pennsy vanla, ing a citizen of the United States, have invented certain new and useful Improvements in Pneumatic Hammers, of "which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which 'ill ustrate the preferred form of the invention,
be understood that the in- S. J OHNSON,
of constructionshown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.
Insaid drawings: Figure 1 is a view in side elevation of a rivet set embodying the 1 end of p n, one or more I vide an improved taining pin whereby ,tainingpin 1s features of the presentjnvention. Fig. 2 1s a longitudinal vertical central section therethrough taken on a plane indicated by line 2-2 of Fig.1,the retaining spring being seen in elevation. Fig. 3 is a transverse horizontal section taken from plane indicated by line 3-3 of Fig.2, the retaining spring being indicated in elevation.
The object of this invention is to improve the construction of the working end of pneumatictools, the particular feature of the improvement being the provision of a rivet set of uniform diameter practically from end to end, without circumferential ooves which weaken th'e'set. Employing this formof set the invention comprises in combinationfa, cylinder formed with an internal shoulder against which the inner the set is-adapted to abut.
In lieu of the customary circumferential groove for. receiving the spring retaining grooves are'providedin the set and the reprojected: through apertures in the wall of the cylinder and into said groove. I
A further object of the invention is to proarrangement of the reit is reversible for distributlng wean:

Application filed March 31, 1910. Serial No. 552,727;
Referring to the drawings by numerals:
1 indicates the casing or cylinder of a pneumatic hammer and 2 the rivet set having the button head forming recess 3. 'The inner end of set 2 extends within the cylinder 1, as usual, and abuts against a shoulder -5 of the casing. Spaced longitudinally of the length of set 2, is a short longitudinal groove 4. Additional grooves 4 may be provided if desired without materially afiecting the strength 05 tlgie y set. The retaining pin 7 1s carrie and preferably formed integral with an casing or cylinder, it is only necessary to withdraw the set. Obviously pin 7 may be introduced through either of the apertures 9 and accomplishes the functions in the same manner.
As clearly seen in Fig. 2, groove 4 is formed with the inner bevel terminal 4, and the inner end of pin 7 is formed with corresponding beveled portion 7 adapting the set 2;:Qto have the maximum longitudinal outward travel with a minimum length of groove 4. Also, it will be noted that by reversing the arch spring 8 and the retaining pin 7 into the opposite aperthe retaining pin will be disposed for contacting with Thus the endoftheretaining pin will be subjected to wear from contact with the end of he groove 4 on one side or, the other .according to therelative' position of the arch bar. i P
I extend into A aper' th for retalning spring the pin 7 out of the groove 4 and ture -9, the opposite side of the inner end of from the inner end thereof,
