In the use of wrenches it is very often desirable to have the work-engag1ng surfaces of the wrench placed at different angles, or

positions relatively to the handle so that the berto be swung to varlous angles so that 1t"55 v 5 wrench may be available for handling nuts or bolts, in otherwise inaccessible posltlons. The present invention 1s deslgned to accomplish this purpose by connecting the handle with the wrench member through a pivotal 1 connection so that thehandle may be adjusted to different angles to the wrench member and thus increase its availability Preferably also the engaging surfaces of the wrench are in a removable end inthe wrench member so that different shapes of wrench slots, or wrench sockets may be provided for the wrench member. Features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings as follows Fig. 1 shows a plan view of the wrench, parts being broken away to better show construction.

Fig. 2 a similarview of a reverse side of the wrench.

1 marks the wrench member. This has I a rearwardly extending plate 2 with anarcuate end 3 and this engages atongue 4 having an arcuate end 5 and extending from a handle 6. A removable plate 7 is secured on the member 1 by a screw 8 and extends over thetongue 4 forming with the plate 2 a slot for receiving the tongue. The plate has anarcuate end 7 a corresponding to theend 3.

A pivot pin 9 extends through the plates 2 and? and the tongue'4 forming a pivotal connection between the handle and the wrench member. A screw 10 is screwed into a per foration 11 in the pin 9. The pin extends through a slot 12 in thetongue 4, this slot permitting freedom of relative. radial movement between the members so as to separate the arcuate edge 8 from a shoulder Gan at the rear of thetongue 4.

The handle portion is provided with acatch 13 preferably made of hardened steel 50 and secured in the handle portion by a screw desired.

1301.. This catch operates innotches 14 in the-arcuatefedge3 and is adapted to lock the wrench member invarious adjustments of its pivotal movement to permit the Wrench mem- "so as tobereleased from thenotches 14 and as r pressure is restored to the handle it tends to force the catch into the notch and as the wrench is used. the tendency is to exert pressure endwise so as to maintain the catch in locking position. Awrench end 15 has ashank 16 which extends into a socket 17 in the wrench member 2. This end is prefer I ably off-set so as to make its one face flush'7o with the ends of the plate 2. A spring 18 is secured by the screw 8 and operates in aslot 19 in the plate 7 the end of the spring having a hook adapted to engage ashoulder 20 and thus lock the wrench end with the wrench "'75 member 2. The wrench end has the usual wrench aws, or work-holding devices 21.

ribs 7 b which engage ribs 1a on the wrench vv member 1. Thus making the wrench member provides an easy manner of making the socket 17 and also the slot for thetongue 4. I

In operation the wrench member is set at any angle relatively to the handle that may 3 position it for the most convenient use and the wrench end is provided having the proper slotting for engaging the size b0lt,'or nut ceiving slot; work-engaging means extending into the socket; and a locking key on the 10 handle coacting with the radially arranged slots for locking the handle with the member.

2. In a wrench, the combination of a Wrench member having radially arranged slots and a wrench-end receiving groove; a plate secured on the member, said plate form ing a tongue-receiving slot at one end of the member and co-acting with the grooveto form a wrench-end receiving socket, said plate having flanges receiving the edges of the memher; a handle having a tongue extending into the tongue-receiving slot; work-engaging means extending into the socket; and a locking key on the handle coacting with the radially arranged slots for locking the handle with the member.

3. In a Wrench the combination of a wrench member having a wrench-end receiving groove; a handle pivotally secured on the wrench member ;.a plate covering the groove and forming a wrench-end receiving socket; a screw securing the plate to the member and the wrench-end in the socket; and a spring in the socket locking the wrench-end in the socket, said spring being secured by said screw.

In testimony whereof I have hereunto set my hand.
