IBRAOE WRENCH.

Application filed April 22,

This invention relates to brace Wrenches Which have a plurality of sockets of different sizes, mounted in turret fashion on the end of the brace and each adapted to be turned into alignment With the axis of the brace for use in turning nuts or bolts.

One of the objects or the invention is to provide a Wrench of this type which is easily made of few and simple parts, of rugged construction and low cost.

Another object of the invention is to provide a brace Wrench with a socket member containing a plurality of sockets, as described, rotatably mounted on the shank of the Wrench, and to provide an improved means for holding any one of the sockets in nut engaging positions, with the nut engaging socket substantially in line With the aXis of rotation of the Wrench.

Another object of the invention is to provide a rotatable handle for a brace Wrench, Which may be made of one piece of metal and may be easily and quickly attached to the shank of the Wrench.

Another object of the invention is to provide a multiple socket member rotatably mounted on the shank of the Wrench and held against lateral motion thereon.

Other objects of the invention will be apparent as the description proceeds.

In the dra-Wings: Y

Figure 1 is a side elevational View of an embodiment of my invention, with the socket and handle members in section, to

show the mamier of attaching the same.

Figure 2 is a bottom` plan vievv of the socket member showing the means for holding the desired socket in operative position.

Figures 3 and 4 are sectional side elevations of tvvo modications of the Wrench shown in Figure 1 and in which the socket member may be more positively secured in nut engaging position; and y Figure 5 is an enlarged sectional view of a portion of the socket shown in Figure 1 showing a modified form of retaining means.

The Wrench comprises a shank 10, bent in such a form as to provide an end portion 11 substantially in line with the -aXis of rotation of the Wrench, a middle or crank portion 12 which is adapted to be grasped by the hand to turn the Wrench and al portion 13 substantially at right angles to the crank 1926. Serial No. 103,767.

portion 12 upon which the socket member 14 55 is rotatably mounted in line with the end portion 11.

The diameter of the end of the transverse portion 13 of the shank 10 is reduced at 15 adjacent the end thereof and forms a shoulder 16, against which the socket member 14 abuts.

A disc or Washer 17 is non-rotatably secured to the end of the transverse portion 13 of the shank 10,. which may be slightly tapered at 18 to receive the same, and the end of the shank is swaged over at 19 to hold the Washer 17 rigidly thereon.. The socket member 14 is held between the shoulder 16 and the disc 17 against lateral movement on the sha1-1k, but is permitted to rotate around the axis 15.

The disc or Washer 17 is provided With a plurality of holes 20, one for each socket 14 preferably, and a spring-pressed ball 21 is mounted in an opening 22 inthe side of the socket member 14, and urged outwardly by the spring 23' against the disc 17. The ball is held in the socket member 14 by the usual method of peening the outer edge ot the opening 22, so that it is slightly smaller than the diameter of the ball. The holes 2O in the disc' 17 are spaced from the center the same distance the ball is set from the center of the socket, so that when the socket is turned with relation to the disc, the ball will engage each of the holes in turn. When the ball is engaged with one of the holes, the socket is held in that position until enough torsional force is directed against 490 the socket to force the ball back into the opening 22, depressing the spring 23, and cause it toV travel over the edge of the hole 2O and along the side of the disc as the socket is turned until it eng-'ages with another ot the holes 20. The holes 2Ov are so placed in the disc 17 that when the ball 21 engages any one of the holes, one of the nut engaging sockets will be in the line of rotation of the Wrench, in proper position to engage a nut for turning.

1f desired, a plurality of spring pressed balls may be used to engage with several of the holes at the same time to increase the turning resistance of the socket member, or a plunger 21a (Figure 5) having a coneshaped head may be used in place of the ball 21. Any desired resistance to turning the .a restricted end 39.

socket may be obtained with this latter embodiment of the invention by providing a plunger in which the cone head a greater or less slope. The steeper the sides of the cone head the greater the i'esistance'to turning Will be.

The handle 24 on the end of the wrench oppositel the socket is comprised ot one piece ot' metal, spun or pressed into a closed or cup shape. flhe upper end oit the handle 24; is turned inwardly and downwardly, torming a sleeve 25, which acts as an upper bearing on the shank 10, and the lower portion 26 of the handle 2st is closed about the shank l0, to form the lower bearing for the handle. r1`he upper portion 11 oit the shank l() has an annular groove 27, near the end thereof, in position to hold the handle 2l in the desired longitudinal position on the shank. A hole 28 is provided in the handle 2a on a 'horizontal' line with the mid portion of the sleeve'25. To attach the handle, it is slipped over the end portion 1l of the shank l() and a tool or punch 29 is inserted through the hole 28 and driven against the sleeve 25 'to provide a project-ion 30 on the insite ol' the sleeve 25 which engages with the the end portion ll of the shank 10, and rotatably holds the handle in place thereon.

It desired, l may also provide a suitable turning handle on `the crank portion l2 of the wrench.

It Will thus be evident that l. have provided a brace wrench with a plurality olf sockets for engaging different sized nuts, iii which any one of the sockets may be used by merely turning the socket member, so that the socket 'is in the proper position and groove in 'in which the socket member will be retained 'in' proper position against accidental rotation, but may be readily turned to another posit-ion to engage a nut. of a diilerent size A when desired.

In Figure 3 a multi-socket member 1st" is 'shown retained uponthe shank 15a by two '

discs

31 and 32.

r1`he disc 3l may be niade integral with the shank l5, il desired. The socket member 141 may have a plurality of plungers 33 disposed iii openings 34.- in the socket member 1ct and urged toward the disc 3l by the springs 35. 'lhe disc 3l may have au opening 36 adapted to register with any one ot the openings 311 when the socket member is turned to the proper positionA on the shank. A second plunger 37 may be mounted in the opening 3G of the disc 31 and may be held therein by the sleeve 38 which has tached to the plunger 37 so that it can project through the end 39 of the sleeve 38 and a'finger piece 41 may be attached to the end of the shaft 40 in order to provide means to operate the plunger 37. 1n this modilication when one ot the holes 34- is aligned with the hole 36 in the disc 31, the plunger 33 is iig/ashes A shank l0 may be atinside i'ace of the disc 31, at which time the socket member llb may be turned on the shank 15a. Vrlhe holes 34 in the socket member la!) are spaced so that when any one of the holes is registering with the hole 36 in the dise 31, one oit the sockets is in nut engaging position.

ln rig-ure l a slightly different modii'ication ot the construction shown in Figure has been illustrated. il socket lll@ is retained on the shank 1:3 by means of discs 32 and a2. il plurality of holes may be provided in the socket lll-C and spring-pressed plungers lll provided therein similar to those shown in lligure 3. il screw is threaded through. a hole sie in the disc. l2 in such a` position that will register with the center of any one ot the plungers lllwhen the socket. 1i .is in the proper position. The hole 16 is enten-ged at the inner face ot the disc 42 to :torni a recess al? adapted to receive one of 2:3 to facilitate turning the same. ln this niodilication, when it is desired to lock the socket ifi-.U in one of its nut engaging positions, the screw l5 is withdrawn by turning the head lle. Wvhen vthe other end ofthe screw lo reaches the bottom of the recess 47 one ot the plungers del is i'ree to be pushed into the recess so that the socket is locked in that position. To change the socket, the screw 45 is turned further into the disc 42 by turning the head 43 when it will :torce the plunger 44 back into the socket 14C to permit the socket being turned on the shank 15a.

l/Vhile V1 have illustrated and described certain embodiments oit my invention, it WillV be i evident that various changes in the design yand construction thereof may be resorted to without departing F from the spirit of the n- `veiition, and l` do not desire therefore to 'limit myself to the embodiments shown and to interpret the invention the scope of the appended said multi-socket member in any one of its nut engaging positions.
