WRENCH.

[1332 ljfp fiaijflmsem U ITED STATES "PATENT OFFICE.
FRED I-IANsEN, OF PULOIFER, WISCONSIN.
WRENCH. v
SPECIFIGATION'forming part of Letters Patent No. 534,064, dated February 12, 1895.
' zen of the United States, residing at Pulcifer,
county of Shawano, and State of Wisconsin, have invented a new and useful Improvement in renches, of which the following is a specification. I
The object of the invention is to provide a wrench which will be capable of operating in obscure and out of the way places, and one which can be variously adjusted to "suit'the size of the nut or the position in which it is arranged. This end Iattain by certain novel features of construction and combination and arrangement of parts that will be more fully described hereinafter and finally embodied in the claims.
In the accompanying drawings: Figure 1' represents a perspective view of my wrench; Fig. 2, a longitudinal section thereof; Fig. 3, a detail perspective of the head; Fig. 4:, adetail perspective of the pawl bar for holding the head; Fig. 5, a detail section.
The reference letter a indicates the shank or body of the wrench, which is preferably cylindrical in shape and provided at its rear end with a squared stud a, upon which the operating rod 17 is arranged and held in place by means of a nut b; By this device, rod 5, the wrench is operated.
Formed longitudinally in the shank a is the passage 0, which communicates with the front end of the shank and is provided for the reception of the longitudinally-movable rod 0'. The rod 0' has its front end reduced, at d, and has the cross-rod d fixed to its middle and projecting beyond its sides and into the longitudinallyelongated slot e of the shank. The purpose of this construction is to allow the rod 0' a limited longitudinal movement in the passage 0.
The rear end of the rod 0 is reduced, at
. e aild screw threaded so as to receive the nut e, which serves as a shoulder for the spring f which is located in the passage 0 and which operates to push the rod 0 forward. One end of the cross-rod 01 extends beyond the body ct-and is formed with an enlargement or head thereon by which it may be grasped, so as to move the rode in its passage c.
The front end of the body or shank a is Application filed March 8, 1894. Serial No. 502,940. (No model.)
formed with two integral lugs g thereon, which are duplicates of each other and arranged oppositely. Located between. these lugs, and pivoted therein by the pin f, is the semi-circular stud g. of the head 72. The head his formed with the stud g thereon, and the curved rear side of the stud is formed with the notches g therein, with which the front end of the rod 0' is adapted to engage. By this construction the head h may be locked rigidly on the shank in any position to suit the location of the nut. Formed in the head is the forwardly-projecting stud or arm h, which leaves an indentation h? in which the swinging arm or jaw 71 is pivoted by means of the pin 01'. The arms h and i comprise the jaws of the wrench, and the latter jaw is adapted to move toward and from the first in the operation of adjusting it to the nut.
This operation is effected by the female screw is, which is arranged in the opening is of the jaw or arm h and provided with a head Z by which the screw may be revolved, while the lower end of the screw is provided with a flange Z which prevents the screw from being removed.
Operating in the screw is is the threaded rod m, which is pivoted inlthe recess m of the jaw 2', by means of the pin m Thus it will be seen that by operating the screw the rod 0% will bedrawn toward or moved away from the jaw h, thereby causing jawt' to move similarly. I
In the operation'of my invention the jaw 'L is adjusted to suit the size of thenut and the head It adjusted on the shank to permit the operation. It will now be possible to use the wrench as ordinarily and as will be understood.
Having described my invention, I claim 1. A nut wrench comprisingin its construc tion a head, an arm or jaw rigid thereon, a second arm or jaw hinged to the head, a threaded rod pivoted to the hinged jaw, and a female screw revolubly mounted in the fixed jaw and having the threaded rod operating therein, substantially as described.
2. In a wrench, the shank a having the passage c and slot 6, the longitudinally-movable rod 0' received within the passage, the cross rod 01' fixed to the rod and working in the slot, the rear or inner end of the rod being threaded, the nut e working on the threaded adapted to be engaged by the front end of the end of the rod, and the spring f hearing at rod 0', substantially as described. one end against the closed inner end of the 1 passage 0 and at the other end against the FRED HANSEN 5 nut, in combination with the wrench head it Witnesses:
pivoted at the front end of the shank and hav- CARL ODEAN, ing at its inner end the curved notched stud HENRY SMITH.
