To aZZ w/imm it'may com:

Be it known that l, *PATRICK J. Km'rmo. a citizen of the United States, residing at J-hicago, in the county'of Cool: anclState of Illinois, have iii-vented certain new and useful improvements in Soft-F lrlarmuers,

of which'the following is a specificatioh.

My invention relates to hummersfanrl more oertieulz-irhi' to hammers having. a soft end "which ma into the hammer hotly in which form it is found that after the head has been used. and is b'a't'teretl mid the 'ineta l of the threaded portion stretched, it is almost impossible to remove the head in order to insert a, new.

one. To avoid this difficulty, it has been suggested that the threads be omitted and a transverse openingbe mad in the hammer body j 11st below the head or removable plug, and a wedge inserted therein for (lriving the head out; but in this form the bottom of the plug is not seated against the solid portion of the hammer, the result being that the hammer face becomes concave, and, for another consideration, a firm blow with the full and unyielding force of the hammer cannot be given. Numerous other clisatlvam tages occur in the use of this construction.

It is the object of the present invention to overcome all objections of the kind mentioned, as Well as others, and to provide a hammer which shall be simple'ancl cheap.

in n'ianufacture, "which will deliver the full effective power of any hammerof the same size and Weight, which shall have a soft head, and one Which will remain in the. hammer during everylrmcl of service and which shall be easily movable at any stage of Wear and which Willuot, by Wedging action of the hammer head llZSBlif upon the hammer body, cause the body to expand and be rendered less useful, or capable of having another head. of standard size substitute-51' as occasion may require or suggest.

In the accompanying" drawings forming: part of this specification]: have illustrated a preferred embodiment of these improvements, the illustration being that of 3..

Fig. 2- is e hiedisl cross louloleeritle cl hammer or sledge, although-it 1? @Vlfilfilll? that the invention may be bract 'ed equally "Well in single-ended hammers of various sizes'and'sha 'ies, and adapted to many different uses lIllJlIG mechanic arts.

in these tlraivings-l igure l is fade VIlGW of the hammer complete, ericept *iior the haiiclle which is partie l""'=brol ii 'clfthe halm 111Ql"l)0i'l"ll&lll at right-angles'totlie view of Fig. '1, or on the plariecf the line2--2 of Fig. 1. In this ViQW the heads and a.

The hammer hotly 10 is pr'e lerablv loads of cast steel antl is provided eye ll for the accommodation ot' the woocleuilfiaw clle 12-. aASflE-Oiill ends of the hammer fillies tratecl are alike, it will be necessary to describe but one. The end of she hemm er body-is provided with a recess 13 having the sides substantially vertical to theface 14.-

of the hammer body, said recess having a bottom 15 substantially parallel with the face 14:. Between the bottom 15 and the sides of the recess I prefer to leave a small fillet 17 for purposes of strength. The hammer head is also provided with a slanting aperture or hole 16 leading from the middle portion of the bottom 15 to one of the sides of the hammer body. The plug or heacl 17 is made preferably of copper, although it may be formed of lead' habbitt, or other of the softer metals, according: to the particular use for which it may be clesireol. The portion 18 of the head 1'? is adapted to fit nicely Within the recess 13, this portion being of such length asto seat itself firmly upon the bottoni 15. This beacl also car ries an extended portion adapted to seat upon the face 14 of, the hammer body. It will thus be seen that the entire projected area of the face of the hammer falls upon/ the solid hai mer body, except for the smallv area of the hole 16 in the bottom. 15 of the head 1? thus fitting the recess 13 and being seated in the manner indicated. becomes Well fixecl Withmusa e and does not re dire aware; v

by any of the usual means at the hands o the plug recess. I have found that the plug or i mechanic, such as a vise e1- ehisell In order to remove these heads quickly and easiiv, ehere'fere, I previde the hole 16, giving aeeess to the hot-om of the plug. By insering a punching too as 20, in the opening 15, and applying hammer blows to the exneseei end of the teal izhe head is chsledg' A an forced cut of the hmnmer body. 1 prefee ably give punehing @001 a slanting face, as shewn, se that it will engage the foe-$9.0m of the head in a way so prevent expending the'metel of the heeai The oblique disposifiion of the passages 15, together with lecation equafiy at opposite sieles of the eye 11, preserves the balance of the body, While the strength and "Weight of the body are not mefieriaily reduced.
