RATCHET-WRENCH.

answer.

Application filed March 19, 1913.

To all whom it may concern Be it known that I, Gonoon K. lVnion'r, a citizen of the United States, and resident oi? Hinsdale, county of Dupage, and State of Illinois, have invented certain new and uselt'nl Improven'ients in Rat(whetrenches, of which the following is a specification, and which are illustrated in the aceon'ipanyiug drawings, forming a part thereof.

The invention relates to wrenches and more particularly to those having a socket for application to the member which is to be rotated and ratchet mechanism permitting a reverse movement of the handle without removing the socket from such member.

The object ol' the invention is to provide a wrench which shall be of simple and inexpensive construction and ellicient in operation.

The invention exemplified in the struchire to be hereinafter described, and which is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation showing a wrench eml'iodving the 'leatures (it improve ment provided by the invention and details of a nut and bolt to which the wrench may be applied. Fig. 2 is a plan view of the wrench showing one of the parts removed and certain other parts in section. l igs. 3 and a are sectional views taken on the lines it 3 and ll, respectively of Fig. 2, and

Fig. is a perspective view showing a detail of the construction.

The wrench is shown in the drawings as comprising a handle, 10, and a head which is generally designatml l1. For convenience in constructioi'i the head, It, will prel erabl v comprise a pair of side plates shown at 12 and 1 apart a su'llicient distance to receive a pawl, 14:, between them, and one of the plates. as 12 is shown as being :tornnnl integral with the handle, 10. The other side plate, '13, is preleral'ily r-=epa1ately formed lrom the handle, but firmly held in position when the parts are assembled, as by rivets l and 16.

The rivets, 1.5, 16, are passed through the side plates 12 and t3, and through the spac ing members, as 17 and 18 between the plates. The s iacing members, 17 and 1S, serve to maintain the plates at the required separation to permit of the operation of the pawl, 14, between. them. As shown, these Specification of Letters Patent.

These side plates are spaced Patented altar. it), Ittlttt.

Serial No. 755,350.

spacing members are both ilormed integral with the plate t2 and handle 10, and one ol? them, as 17, is made round to serve as a pivot for the pawl. The other spacing member, 15, has a configuration similar to that of the pawl, ll, and constitutes a closure for the space between the plates at that side remote trom the pawl. l

The pawl, ll, cooperates with the teeth of a ratchet, '19. This ratchet; is .toruuxd upon the peri ihery o'l a sleeve, 20, which is rotatably mounted in the head, 11. lre'lerably the two side plates 12 and lil oi? the head, 11, are apcrtured, as indicated at it and to provide bearings for the opposite ends ol the sleeve, ikll. The ratchet, '19, being" V U ormcd upon the sleeve E20, between the plates 12, 13, serves to prevent displacenient ol" the sleeve when the plates are held together by the rivets l5 and it). A spring, i l, located between the side plates 1'2 and 13 and reacting between the rear end of the pawl, it, and the inner 'l'ace ol? the spacing member, 18, serves to hold the pawl in operative engagement with the ratchet, 1!).

A, socket, will u.--uall be employed for engagement with the member to be turned, as the nut X. in order that thi socket may be located at either side of the head, ll. it is prc'l'erabl provided with a stem, 35, adapted to removablv enter the bore of the sleeve, Qt). 'lo prevent relative rotation 01' the socket, Q-Ll, and sleeve, 20, the stem ot the socket and the bore of the sleeve are oi eorrespoiuliug angular shape. leaf spring, 90, located in a reces--r, 27, in the wall of the sleeve. 20, and protruding into the bore of the sleeve engages the stem. 25. ot the socket member to vicldiugly hold the lat ter against removal. As shown, the spring, 36, is held in position by a rivet, 29. pa sed thrl'iugh one end ol the spring and into the wall ol the sleeve. Most dcsirablv the stem, 95, ot the socket member. 2t, is made tubular to receive the protruding cud ot a bolt, as Y, upon which the out, as X runs.

In the use ol the wrench, the socket ll10111-- ber, 9t, will be applied to that side ot the head, 11, adapted to permit; the pawl, ii, to turn the ratchet, if). in such direction as it is desired to turn the nut, as X to which the wrench is to be applied. For this purpose, the stem, 25, ot the socket member, 9 1-, is passed into the bore of the sleeve, 20, from the side at which the socket member, is desired to be located. The arrangement by which the socket member, 24, may be located at either side of the head, 11, permits the use of the wrench, with but a single pawl, 14, for turning the nut, as X in either direction.

he device is accordingly of simple con struction and all of its parts may be made from cast metal without finishing with machine tools. The construction of the spacing member, 17, whereby it serves as a pivot for the pawl, l l,providesincreased strength, as also a free movement of the pawl. Fur thermore, the inner end. of the handle, 10, provides a shoulder, 29, part of which is in a direct line with the thrust of the pawl. The wrench may be conveniently used for the turning of nuts which are located in difiicultly accessible positions. The use of the socket, 24, for engaging the nut to be turned and the provision of the tubular shank, 25, permit the nut X and )rotruding portion of the bolt Y to effectively hold the wrench in position when it is once applied. The entire attention of the operator may accordingly be given to the turning of the handle, 10. If desired, a plurality of sockets of different size but having stems, as 25, of like dimension may be interchangeably used for engagement with nuts which differ in size or shape.

I claim as my invention 1. In a ratchet wrench, in combination, a handle, a pair of parallel plates at one end of the handle, one being formed integral with the handle and the other being removable, a socket member extending transversely through the plates and being journaled therein, ratchet teeth. formed on such member between the plates, a tubular spacing stud formed integral with that one of said plates which is formed integral with the handle and extending toward the other plate, a pawl pivetally mounted on the said stud, and a bolt or rivet connecting the plates and extending through the bore of the said stud.
