WRENCH..

SPECIFICATION forming part of Letters Patent No. Im0,;305, dated January 17, 1905. Application tiled February Il, 1904. Serial No. 192,053.

.To all whom ift may concern:

Be it known that I, H nNicY H. Eier-irma citil zen of the United States, residing' at Altoona,

county of Blair, and State of Pennsylvania, have invented a certain new and usei'ul lmprovement in Wrenches, oi which the follow ing is a speciiication.

My invention relates to a new and useful iinprovement in wrenches, and has for its object to provide a wrench in which the movable jaw may be moved to any position along the shank and quickly set in place, and the movable jaw is constructed upon one side with a beveled surface, which beveled surface is provided with teeth, so that by reversing the jaw the device is converted into a pipe-wrench.

With these ends in view this invention consists in the details of construction and combination of elements hereinaii'ter set forth and then specifically designated by the claim.

In ord er that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referringto the accompanying drawings, forming a part oi' this speciiication, in which- Figure l is a side elevation of my improved wrench; Fig. 2, aside elevation of the wrench, a portion of the same being broken away; Fig. 3, a section on the line 3 3 of Fig. 1.

A is the iiXed head of the wrench, which has formed with it the shank B. The rearward end oi' this shank is provided with notches extending laterally across the same, as represented at C. The rearward portion oi' the head A is made in the form of a hammer-head D, so that when the movable jaw is removed from the wrench the device could be used as a hammer.

E represents the movable jaw through which the shank B passes, so that the movable jaw may slide upon said shank. rlhe rearward portion oi' the jaw E is forked, the prongs E passing' each side of the shank B and a considerable distance to the rear thereof.

F is a block which is adapted to slide in between the outer ends of the prongs E', and these prongs E have inturned ends which lit over a iiange upon the block F. This block F is then secured in place by the pins F, which pass through the prongs and also through the block.

G is a set-screw which is threaded through the block F, as shown in Figs. 2 and 3.

Il is a gib which is adapted to lit between the prongs E and between the shank B and the block F. rlhe face of the gib next to the shankis provided with teeth to correspond to the notches C in the shank. Suilieient distance is left between the gib H and the block F to allow ior the gib being drawn out of engagement with the notched surface C ot' the shank. The inner end of the set-screw G is provided with an annular groove G', and this inner end fits in to a circular hole formed in the gib. Pins l pass through the gib upon each side of the setscrew through the annular groove (Jr, so that said set-screw is swiveled in the gib, as shown in Fig. 2. Thus as the set-screw is threaded through the block F when said set-screw is turned in one direction or the other the gib is either raised out of contact with the shank or forced into contact therewith. Upon each end oi2 the gib are Yformed rearwardly-extending flanges H, which pass upward upon each side ot' the block F and serve to guide the gib in its movement. One side oi" the movable jaw E is straight and smooth, and this side is turned toward the iixed jaw and is opposed to the same when the device is used as a monkey-wrench. The other side of the jaw forward of the shank is beveled, and this beveled surface is provided with teeth Ff, and as the handle B, formed with the shank, is no larger than the shank the movable jaw F. may be slid from oif the handle and placed upon the shank again in a reversed position, so that the teeth E2 will be opposed to the lixed jaw, and the device can then be used as a pipewrench.

The advantage of my improved wrench is that by one turn oi the screw G the movable jaw is reversed so as to be slid at any point along the shank, and then by turning the screw back this jaw is tixed securely in place, and therefore the wrench can be adjusted quickly to any size nut and will have a greater range of movement than an ordinary monkeywrench, and by Vforming the movable jaw as shown a pipe and monkey-wrench are-com- IOO bined in one, and by removing the movable jaw entirely the device can be used as a hammer, and l accomplish this by an extremelysimple construction, and yet the wrench Iis exceedingly durable and is not liable to get out of order.

Of course I do not wish to be limited to the exact construction here shown, as slight modications could be made without departing' from the spirit of my invention.

Having thus fully described my invention, what 1 claim as new and useful is# In a wrench, a fixed head, a shank formed with said fixed head, a handle formed with the shank no larger in cross-section than said shank, a movable head through which the shank extends, the rearward side of the shank being' provided with a series of notches, the rearward portion of the movable head being fork shape, an inwardly extending flange formed at the outer end of each of the prongs of the forli, a block rabbeted upon the sides so as to fit underneath said flanges and be flush with the upper surface of the same, said block adapted to be slid in between the prongs endwise, pins passing through the prongs and through said block, a gib interposed between the block and the notched surface ofthe shank, teeth formed upon the in- 'ner face of the gib adapted to engage the notches, a screw threaded through the block and swiveled in the gib for raising and lowering said gib, means for guiding said gib in its movements independent of the screw, the forward end of the jaw of the movable head being formed iiat on one side and beveled on the other, the beveled surface being provided with teeth so that when the head is reversed the wrench can be used as a pipe-wrench, as and for the purpose specified.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
