Definitions
- the main bar 1 of the wrench is provided on one end with a square head .1. adapted to be clamped by a socket wrench, or a wrench having a movable jaw.
- the opposite end of this bar is hinged to a connecting block 2 by means of pivots 1", passing through the sides of the block, and the block 2 is hinged to the ears 3 of a socket head 4 by means of pins 2 extending through the ends of the block at right angles to the pins 1", thereby forming a gimbal or universal joint between the bar 1 and the socket head 4 connected therewith.
- the socket head 4 is provided with an enlarged boss 5 which is provided with a recess 5 having its walls arranged at an angle to each other, as indicated in Fig. 3.
- the boss 5 of the socket head 4 is also provided with a spring 6 rigidly secured at one end to the socket head by means of screws or pins 6 and having its opposite end free to bear against a pin 9 having a sliding engagement with the socket head and projecting into the recess 5 formed in such head so as to be adapted to engage a corresponding recess formed in an auxiliary socket head 7.
- the socket head 7 is provided with a boss 7 indicated" by dotted lines in Fig. 1, having its sides formed at an angle with each other and adapted to be received by the recess 5 formed in the main socket head 5 attached to the bar 1.
- the boss 7 of the socket head '7 is also provided with a recess corresponding in outline with the end of the pin 9 projecting into the recess 5 formed 'main socket head 5'.
- auxiliary socket head 7 may be modified without departing from my invention, so as to adapt the wrench to be used under different conditions.
- a short auxiliary socket head may be used similar to the socket head 7 already described herein, having a boss '7 iormed directly on to the socket head. 111 other instances, however, it is not possible to use a short socket head.

- the wrench may be connected with a belt or nut in any position or location however inaccessible to the ordinary wrench, and may be provided with a suitable auxiliary socket head, and the main socket head and auxiliary socket heads rotated by the bar 1. while extending in a plane at an angle to the plane of the main and auxiliary socket heads.
- the bar 1 is provided with cars l, which bear against the side walls of the connecting block 2.
- the ears 3 of the socket head 4 are also adapted to bear against the end walls of the connecting block 2, so that when the bar 1 is rotated the ears 1 of the bar and the ears 3 of the main socket head will have a broad bearing on the walls of the connecting block 2, and thereby enable considerable torsional strain to be exerted on the bar 1 and the socket head clamping the belt or nut, without weakening or injuring the parts of the device.

UNIVERSAL WRENCH.
Specification of Letters Patent.
Patented Oct. 15, 1907.
Application filed July 27,1906. Serial No. 328,071-
adapted to be used in places inaccessible to the ordinary socket Wrench, or wrench having a sliding jaw, and also to provide means for adjusting and regulating the length of a socket shank adapted to be used with such a wrench. These objects I accomplish by the means illustrated in the accompanying drawings, in which drawings like charactersof reference indicate like parts throughout the views, and in which Figure l is a side elevation partly broken away, of a wrench embodying my invention applied to a stud bolt attached to a bracket; Fig. 2 is a side elevation of the wrench shown in Fig. 1, partly broken away, having a socket head provided with an elongated shank secured thereto; Fig. 3 is a plan view of the underside of a main socket head attached to the wrench shown in Fig. 1; and Fig. 4 is a plan view of the underside of an auxiliary socket head adapted to be attached to the wrench as illustrated in Fig. 2.
As illustrated in the drawings, the main bar 1 of the wrench is provided on one end with a square head .1. adapted to be clamped by a socket wrench, or a wrench having a movable jaw. The opposite end of this bar is hinged to a connecting block 2 by means of pivots 1", passing through the sides of the block, and the block 2 is hinged to the ears 3 of a socket head 4 by means of pins 2 extending through the ends of the block at right angles to the pins 1", thereby forming a gimbal or universal joint between the bar 1 and the socket head 4 connected therewith. The socket head 4 is provided with an enlarged boss 5 which is provided with a recess 5 having its walls arranged at an angle to each other, as indicated in Fig. 3. The boss 5 of the socket head 4 is also provided with a spring 6 rigidly secured at one end to the socket head by means of screws or pins 6 and having its opposite end free to bear against a pin 9 having a sliding engagement with the socket head and projecting into the recess 5 formed in such head so as to be adapted to engage a corresponding recess formed in an auxiliary socket head 7. The socket head 7 is provided with a boss 7 indicated" by dotted lines in Fig. 1, having its sides formed at an angle with each other and adapted to be received by the recess 5 formed in the main socket head 5 attached to the bar 1. The boss 7 of the socket head '7 is also provided with a recess corresponding in outline with the end of the pin 9 projecting into the recess 5 formed 'main socket head 5'.
in the socket head 5. The pin 9 is held in constant I engagement with said recess in the boss 7 of the socket head 7 by means of the spring 6 which bears at its free end against the outer end of the pin 9. The auxiliary socket head 7 may be modified without departing from my invention, so as to adapt the wrench to be used under different conditions. Where the wrench is designed to be applied to a stud bolt 8 attached to a plate 14 wherein a cross bar 10 lies in the vertical plane of the stud bolt and at a short distance therefrom, a short auxiliary socket head may be used similar to the socket head 7 already described herein, having a boss '7 iormed directly on to the socket head. 111 other instances, however, it is not possible to use a short socket head. Thus where a nut 12 is looked upon a stud bolt 15 which projects beyond the nut so that it cannot be clamped by a short auxiliary socket head similar to that shown in Fig. 1, an auxiliary socket head 11 may be used, which is provided with an elongated hollow shank 11 having an angular boss 11 formed thereon adapted to engage the angular recess 5 formed in the By means of such construction the wrench may be connected with a belt or nut in any position or location however inaccessible to the ordinary wrench, and may be provided with a suitable auxiliary socket head, and the main socket head and auxiliary socket heads rotated by the bar 1. while extending in a plane at an angle to the plane of the main and auxiliary socket heads. The bar 1 is provided with cars l, which bear against the side walls of the connecting block 2. The ears 3 of the socket head 4 are also adapted to bear against the end walls of the connecting block 2, so that when the bar 1 is rotated the ears 1 of the bar and the ears 3 of the main socket head will have a broad bearing on the walls of the connecting block 2, and thereby enable considerable torsional strain to be exerted on the bar 1 and the socket head clamping the belt or nut, without weakening or injuring the parts of the device.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
universal wrench comprising an operating bar, a stub head provided with a socket, a universal joint between said head and bar. a pin movable transversely in said head, a spring secured at one end to said head having its opposite free end engaging the outer end of said pin, and a socket member detachably connected with said head and adapted to be engaged by said pin.
In testimony whereof I lll"0 signed my name to this specification in the presence of two subscribing witnesses.
MAX KORTl'l.
