To all whom/ it may concern Be it known that I, STEPHEN PAUL, a

citizen of thellnited States of America, re- 7 j at Lansing, in thecountv of Ingham an w er Michigan, have ihven'ted' cerfollowing is afspecification, reference being had therein. to "the accompanying drawne "This invention relates to adjustable guides for. 'reciprocable members, and has special reference to the guides in the'housing of a hydraulic or, steam hammer,

as us d f ssi ing urpose My jnventipn in its broadest aspect, involves means for minutely adjusting guides and positively holding the same against accidental displacement during the reciprocation of a member, as a hammer head,"between the guides.

V Specifically, my invention includes tapering members adapted for laterally adjusting guides to compensate for wear and permit of the guides ,being adjusted so as to in 3111154111 a y incr ment of the reciprocable member therebetween, without any danger V ofa binding action or sticking of a hammer head between the guides. Associated With the tapering members are looking. devices that positively hold the members in adjusted position, and my invention will be fully understood when reference is had to the drawing, and the following detail description.

In the drawing,

Figure 1 is a front elevation of a portion of a steam hammer, partly broken away and partly in section, showing the adjustable guides and the means for adjusting said guides;

Fig. 2 is an enlarged horizontal sectional view of a portion of the hammer housing showing a guide adapted to be adjusted by a tapered member;

Fig. 3 is a view of the inner face of a por tion of the housing;

Fig. 4 is an enlarged View of the detached tapered member;

Fig. 5 is an enlarged front elevation of a locking device for the tapered member;

Fig. 6 is a horizontal sectional. view of a portion of the locking device, and

Fig. 7 is a rear elevation of the same.

In the drawing, 1 denotes the frames of a hammer housing and the confronting wen" kn wii yp 99 9209.

r are es nsula a for pockets 2containing wear is. "s 3 for the uid s {9f e re pm a are a 'fi emae n f h e a seam T1 si is edes 4 have screw ing through openings 7 of the and said screw bolts have tapering hheads 8 seated in the guides 4: so that should a screw bolt be injured or accidentally broken,

it may be quickly removed, without discarding the guide held thereby.

At the outer-ends of the frame openin V 7 retina le e terswashers 1Q; said washers havi' lar portions lladapted'to engage 1n the seats 9. The washers ioinso' ave annular recesses 12 to receive cylindrical portion 13 of nuts 11 screwed upon the bolts 6, and these nuts may ,be' adjusted to, lock fthe guides 4 after the same have been prdperly positioned. V j

The housing frames 1 above and beIQwthe th dj s d kinie si cesi 'e' of are identical in constriiction,'Fdeem it only necessary to describe the devices of one of the openings 15.

Each opening 15 is rectangular in cross section with a screwthreaded shank 17 protruding therefrom. Extending into the opening 15 is a non-rotatable washer 18 having a side extension 19. Screwed on the threaded shank 17 is a nut 20 and the washer 18 and the nut 20 are somewhat similar to the washer 10 and the nut 14 previously mentioned. The nut 20, however, has a ratchet portion 21 and adapted to engage the ratchet portion is a spring pressed pivoted pawl 22 carried bv the side extension 19 of the washer 18. The pivoted pawl 22 is normally held in engagement with the ratchet portion 21 of the nut 20 by a spring 23 interposed between said pawl and a lug 24. on the side extension 19. Adjacent the pivoted pawl 22 is a pivoted cam member 25 and this cam member can be swung into engagement with the pawl 22 to hold said pawl out of engagement with the ratchet nut, with the spring 23 under compression.

faces of'these frames are with" an pe ng M ssiaen w th. ass- 4 With the parts in this position, as illustrated in Fig. 5, the ratchet nut 20 can be unscrewed, but when the ratchet nut is tightened, the cam member 25 is swung out of engagement with the pawl 22, so that the pawl will engage the ratchet nut and hold it against counterclockwise rotation. In other words, the ratchet nut is held in the position to which it is adjusted.

With ratchet nuts on the threaded shanks 17 of a tapered member, the tapered member can be shifted in the pocket 2 and in a transverse opening 26 provided therefor in the guide 4, and it is through the medium of the tapered member that the uide 4 can be shifted in and out of the poo et 2 so as to properly engage and guide the hammer head 5.

By using four of the tapered members 16 there may be a uniform adjustment of the guides, thus maintaining said guides in perfect parallelism to insure non-frictional mo ement of the hammer head between said It will of course be understood that prior to adjusting the tapered member 16 that the nuts 14 are loosened to allow sufficient play of the screw bolt 6 in the opening 7 in order that the guides 4 can be moved, and after said guides have been properly adjusted relative to the housin frames 1, then the nuts 14 are tightene thus holding the guides 4 against the tapered member 16 and cooperating therewith in preventing accidental displacement of the guides during the reciprocation of the hammer head 5.

It is apparent that the tapered member 16 constitutes means in proximity to the ends of the guides for laterally adjusting the same within the pockets 2 of the hammer housing and that the screw bolts 6 and the nuts 14 constitute locking means,'interposed between the tapered members and intermediate the ends of the guides 4, for holding said guides after'having been adjusted by the tapered members.

While in the drawings there is illustrated a preferred embodiment of my invention, it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claim.

What I claim is j The combination with a housing having frames provided with pockets and rectangular openings, guides in the pockets of the housin frames for a reciprocable member in the ousing, tapered members in some of the frame openings and having screw bolts protruding therfrom and adapted for adjusting said guides, and screw bolts carried by said guides and protruding from the other openings and adapted for locking said guides in adjusted positions, of means for adjusting all of said screw bolts, said means comprising washers having rectangular portions to engage in the rectangular openings of said frames, ratchet nuts rotatable in said washers and screwed on said bolts, spring pressed pawls on said washers normally engaging said ratchet nuts, and cam members on said washers adapted to be manually swung into engagement with said pawls to hold said pawls out of engagement with said nuts.

In testimony whereof I afl'ix my signature in the presence of two witnesses.
