HOFFMAN, AND SIXTEEN ONE-HUNDR EDTHS TO ALFRED H. HOFFMAN.

SOCKET-WRENCH.

Application filed April 21, 1915 To all whom it may concern:

Be it known that I, EMILE R. MIO'ITEL, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in. Socket-VVrenches, and declare the following to be a. full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings. which form a part of this specification.

This inventicn'relates to socket wrenches and an object of the invention is a. wrench in which the socket o-rnut engaging head is pivotally mounted for universal movemen relative to the shank whereby the device is adaptable for use in operating on nuts in positions inaccessible with. an ordinary wrench.

A- further object of the invention is a wrench of the characterstated in which the sockets are readily interchangeable, springs being employed to hold the socket in its position relative to the handle.

A further object of the invention is a device in which the handle is longitudinally adjustable to enable the operator to manipulate nuts that are positioned at some distance from the outside of a mechanism, as an automobile engine mounted in a frame. By lengthening the handle the reach of the wrench is increased.

An additional object of the invention is a wrench of the character stated that may be folded or adjusted to small compass.

With these and other objects in view the invention consists in the construction and the novel arrangement of parts as hereinafter more fully described and claimed and shown in the accompanying drawings in Figure 1 is an elevation of a wrench embodying my invention showing the adaptability for operation at an angle with the' longitudinal axis of the bolt and nut operated on. Fig. 2 is a view of the wrench when folded showing in detail the means employed in holding the operating or turning handle in position. Fig. 3 is a similar view showing the other side of the wrench. Fig. 4 is a side elevation of the socket employed with the wrench. Fig. 5 is a face view of the socket holder.

Specification of Letters Patent.

Serial N 0. 22,744.

Similar characters refer to similar parts throughout the drawing and specification.

The wrench consists preferably of a shank 1, having a bifurcated end 2'pivotally supported in which is a pivot block 3 adapted at one end to receive the ocket 4. As shown more clearly in Figs. 2 and 5, the pivot block or socket support 3 is also bifurcated to receive and pivotally support the tongue 5 of the socket 4. As shown in Fig. 4 this tongue 5 has secured thereto a pin 6, the ends of which are preferably rounded as shown and projecting equidistantly each way from the tongue. Each furcation of the socket support 3 is channeled or grooved at 7 to receive the ends of the pin 6 secured to the socket tongue, and to each furcation of the socket support 3 is secured a flat spring plate 8, the ends of which are curved outwardly as indicated at 9 to enable the socket tongue and pin to be pushed into place readily. The spring plates 8 are apertured at 10 in alinement with the grooves 7 so that, when the pin is seated in the said grooves, the plates spring back into contact with the sides of the socket support 3 and engage over the ends of the pin 6, thus retaining the socket in the support 3. By springing either of the plates sidewise slightly with the thumb or finger, the socket may be readily removed from the support.

By reason of the socket being pivoted in its support and the support pivoted to the nuts in inaccessible positions, the shank is provided with a tubular, telescoping, extension 11. This extension is slotted upon opposite sidesas indicated at 12 in Fig. 3, and at the extreme end of the shank a pin is inserted through the shank 1, through each of the slots 12, and a collar 13 encircling the tubular member 11. These parts are made to fit rather tightly so that some little friction exists between the parts whereby the said extension remains in the position placed and may be drawn out to its fullest extent as determined by the length of the slots or may be set in any intermediate position as may be desired. The tubular part 11 extends beyond the end of the shank 1 and is apertured at 14, 14, as shown to re= ceive the turning handle or operating bai- 15'. This bar is provided with an enlargement 16 at each end to prevent its removal through the apertures 14. A retaining block 17 is also provided in the upper end of the tubular extension grooved to engage the handle and held in frictional contact therewith by mean'sof the coiled spring 18 retained in the extension by means of a screw 19 in threaded engagement with the end of the tubular extension. The handle 15 has a bent end portion 20 extendingsubstantially at a right angle with the body of the handle and of such length that, when the bent portion is drawn through into the apertures 11 as shown in Fig. 2, the body of the handle lies adjacent to and parallel with the shank at which time the tubular extension may be shoved down onto the shank to close the wrench into the smallest possible compass.

From the foregoing description it becomes evident thatthe wrench is of simple form and construction and comparatively inexpensive to manufacture, that it is adaptable for use with avariety of sockets which are interchangeable and readily positioned in the support, and that the universal joint connection with the shank enables the device to be used in positions ordinarily inaccessible with wrenches of the ordinary type.

Having thus briefly described my invention and its utility, what I claim and desire to secure by Letters Patent of the United States is- 1. In a wrench, a shank, a socket support pivotally connected therewith, a socket having a pin secured thereto, the support being adapted to receive said pin providing a pivotal mounting for the socket at right angles to the pivotal mounting of the support, and spring retainers on the support adapted to engage said pin.

2. In a wrench, a shank having a bifurcated end, a bifurcated socket support havof the socket, the ends of the furcations of the support being grooved to receive said pin, and a pair of spring retainers on the support adapted to engage the pin and yieldably hold the socket in place.

4. A socket wrench comprising a shank having a bifurcated end, a bifurcated socket support pivotally mounted in the said bifurcated end, a socket having a tongue adapted I to engage the furcations of the support, a

pin projecting from each side of the tongue of the socket, the ends of the furcations. of the support being grooved to receive the pin, and a pair of flatspring plates secured to the opposite sides of the support having apertures in alinement with the said groove adapted to engage the pin, said plates being curved atthe free ends and the ends of the pin being rounded whereby the socket may be readily attached or detached from the spring.

5. A socket wrench comprising a shank, a socket having a universal joint connection therewith, a tubular extension in telescopic relation with the shank, said extension being slotted upon opposite sides, a collar engaging about the extension and secured to the shank by a pin passing through said slots, and a turning handle mounted in the extension adapted to be folded parallel with the said extension.

In testimony whereof, I sign this specification.
