V UNITED STATES PHILIP RAUGI-I, OF BROOKLYN, NEW YORK, ASSIGNOR TO J. H. FAW, OF WHITE PLAINS, NEW YORK.

BRACE VIBENCH.

Application filed May 3, 1826. Serial -No. 106,276.

This invention relates to brace wrenches which may be adjusted to turn nuts of several different sizes by turning the socket member to place the proper socket in alignment with the axis of the wrench.

One of the objects of the invention is to provide abrace wrench having a multisocket member rotatably mounted on the shank thereof, which may be releasably held in any one of its nut-engaging posit-ions.

Another object of the invention is to provide a brace wrench having a multisoeket member rotatably mounted on the shank of the wrench and means to hold the socket member in any one of its nut-engaging positions, which may be constructed out of few parts and at low cost, and which may be easily and quickly assembled with the socket member on the shank of the wrench.

Other objects and advantages of the invention will appear as the description proceeds. In the drawings, in which several embodiments of the invention have been illustrated:

V Figure 1 is a side elevation partly in section, of a brace wrench embodying the invention;

Figure 2 is a front View of the socket member of the wrench shown in Figure 1;

Figure 3 is a sectional side view of a socket member similar to the socket member shown in Figure 1 but showing a slightly different embodiment thereof;

Figure 4 is a front view of a socket member showing a slightly different embodiment of the socket holding means; and s Figure 5 is a sectional elevation similar to Figure 3 showing another modification.

Heretofore multi-socket wrenches have been provided in which the whole socket is movable longitudinally on the shank of the Wrench to release the socket so that it may be rotated to a new nut-engaging position. In using such a wrench, pressure, is often ex erted on the crank handle in such a direction ber against longitudinal movement on the shank.

Referring now more specifically to the drawings, the wrench comprises a shank bent to form a crank 11 and a socket-supporting member 12. The upper end 13 of the shank supports a handle 14 to facilitate using the wrench. The portion 12 of the shank is adapted to rotatably receive a multisocket member 15 having a plurality of sockets 16 of difierent sizes around the circumference thereof. A pair of spring discs 17 and 18 may be provided at each side of the socket member 15 and adapted to be rigidly attached to the shank of the wrench. This may be accomplished by providing squared portions 19 and 20 on the end of the portion 12 of the shank at either side of the socket member 15 and the discs 17 and-18 may be provided with square openings in the center thereof to engage the square portions on the shank to hold the discs non-rotatably on the shank. A shoulder 21 may be provided adjacent the square portion 19 and against which the disc 17 abuts. The end of the shank 22 may be peened over against the disc 18 to hold the discs and socket member on the end of the shank. The socket mem her-may be provided with a plurality of depressions 23 spaced near the circumference thereof and equi-distant from the center. The discs 17 and 18 may be provided with a plurality of projections 24 which are adapted to engage with the depressions 23 when the socket member is in any one of its nut-engaging positions.

In using the wrench, the projections 24 on the discs 17 and 18 engage the depressions 23 in the socket member and hold the socket member firmly in one of its nut-engaging positions. If it is desired to use another socket, the socket member may be turned on the shank whereby the projections 24 of the discs are forced out of the depressions 23 in the socket member and the discs are sprung or dished outwardly so that the projections 24 ride upon the surface of the socket member until the new socket has been brought into position when the projections 24 will again engage with the depressions 23 and hold the socket against accidental rotation in its new position.

The disc members 17 and 18 may be stamped out of spring sheet steel or other suitable spring metal, the projections 24 and the holes in the center being formed at the same time. The projections 24 and the depressions 23 are shown in Figure 1 as hemispherical in shape but they may be formed conical, as illustrated in Figure 3.

If it is desired to provide a holding means having less resistance to turning the socket member, the discs may be cut out, as shown in Figure 4, to form spring spiders 25. In this modification, the arms 26 of the spiders are more resilient and allow the projections 24 in the ends thereof to pass more readily in and outof the depressions in the socket member and offer less resistance to turning the sockets.

If desired, instead of using a resilient disc, the whole disc may be adapted to move longitudinally of the shank as the projections on the disc pass into and out of engagement with the depressions on the socket member. This may be accomplished by the construction shown in Figure 5 in which the shoulder 21 is spaced far enough from the disc 17 to accommodatea spring 27 between it and the disc. The extended squared portion 19 permits the disc 17 a to move back toward the shoulder 21 against the spring 27 when the socket member is turned and the spring 27 holds the disc in engagement with the socket member when the socket member is in one of its nut-engaging positions. From the foregoing, it will be evident that I have provided a brace wrench with a multisocket member, which may be turned and held in any one of its nut-engaging positions against accidental displacement, and which may be manufactured out of simple parts and easily and'quickly assembled. All the parts are of rugged construction and no small parts subject to easy breakage need be used. It is to be understood that the invention is not restricted to the use of two discs as one may be used with good results, nor to a disc-shaped resilient member for this purpose, as a flat stamping of spring sheet metal of any other shape may be used just as effectively.

The invention is not, therefore, intended to be limited to what has been shown and described, but to be interpreted broadly within the scope of the appended claims.

What I claim as my invention is:

1. In a brace wrench, a shank, a multisocket member rotatably mounted on said shank, said socket member having a plurality of depressions in the sides thereof and resilient means rigidly attached to said shank at each sideof said socket member to releasab y engage withall of said depressions to hold said socketmember in any one of its nutengaging positions.

2. In a brace wrench, a shank, a multisocket member rotatably mounted on said shank, a shoulder on said shank a flat resilient member at each side of said socket member and rigidly attached to said shank, one of said resilient members being interposed between said shoulder and said socket member and projections on said members to flex said members when said socket member is in any but a nut-engaging position whereby said socket member is releasably held in any one of its nut-engaging positions.

3. In a brace wrench, a shank, a multisocket member rotatably mounted on said shank, said socket member having a plurality of depressions in the side thereof, a flat disc at each side of said socket member and rigidly attached to said shank, and a plurality of projections on said discs adapted to register and engage with said depressions on said socket member when said socket member is in any one of its nut-engaging positions, whereby said socket member is releasably held in that position.

4. In a brace wrench,a shank, a multisocket member rotatably mounted on said shank, said socket member having a plurality of hemispherical depressions in the sides and spaced equi-distant from the center thereof, a resilient disc rigidly attached to said shank at each side of said socket mem ber, a plurality of hemispherical projections on each of said discs and adapted to register and engage with the depressions on said socket member when said socket member is in any one of its nut-engaging positions to releasably hold said socket member in such position. I

5. In a brace wrench, a shank, a multisocket member rotatably mounted on said shank, said member having a plurality of hemispherical depressions in the sides thereof spaced from the center thereof there being one depression for each socket, a resilient disc rigidly attached to said shank at each side of said socket member, a plurality of hemispherical projections on each of said discs, one for each depression in the adjacent side of said socket member, and adapted to engage with said depressions when said socket member is in any one of its nut-engaging positions.

6. In a brace wrench, a shank, a shoulder on said shank, a flat resilient member on said shank and abutting. against said shoulder, a multi-socket member rotatably mounted on said shank adj acent said resilient menr ber, said socket member having a plurality of depressions'in the side thereof, a second flat resilient member mounted on said shank adjacent said socket member, means to hold both of said resilient members non-rotatably on said shank, projections on the inner faces of said resilient members adapted to engage with said depressions on said socket member and releasably hold said socket member in any one of its nut-engaging positions.

In testimony whereof I have aflixed my signature to this specification.

PHILIP RAUGI'I.
