SPECIFICATION forming part of Letters Patent No. 308,969, dated December 9, 1884:.

7 Application filed February 19, 1894. (N0 model.)

To all whom it may concern.-

Be it known that I, Josnrrr LUssrnR, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and Improved Wrench, of which the following is a full, clear, and exact description.

The object of my invention is to furnish a wrench that can be uscdin corners and other hardly-accessible places where it is inconvenient or impossible to use an ordinary wrench.

The improvement relates to the class of wrenches having rocking or adjustable heads; and it consists in certain novel features of construction, as hereinafter described and claimed. 1

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of the wrench with a portion of the shank removed, and Fig. 2 is a face view. Fig. 3 is a section of the head, showing the operating-screw and sliding jaw.

A is the handle, which is made in two parts, secured together in any suitable manner. The inner sides of the llitlltll6-SGOblOllS are cut away at their upper ends to form a fork, and are provided with perforations.

The head 13 is circular and formed with two side studs, a a, on either side, which studs fit within the perforations of the handle when its sections are securcdtogethcr, in order that the head may rotate. The head B is cut away to form a fixed jaw, b, and is recessed at c, as shown in Fig. 3, to receive the tongue of the movable jaw c and the o 'icratingscrcw (l. The end of the screw opposite the head (7/ has a bearing in the end wall of the slot, and

the screw is provided at its opposite end with a shoulder, d, which bears against a shoulder, 0", at the outer end of the recess 0'. The screw (2, without its head, is first placed with- .in the slot 0; thcn the tongueof movable jaw c, which is threaded on its under side, is inserted with its threads meshing with those of the screw, and a small block, it, is placed in the outer end. of the slot,with its under side cut away to fit the cutaway part of the screw adjoining the shoulder (i The head (7, is now secured to the screw cl,

which is firmly swiveled in the slot, as shown.

The slot 0 and screw (I extend beyond and across the center of the head with which they are in line, which is easily accomplished, as there is no pivot in the way, owing to the studs a being formed on the sides of the head. By this construction a large adjustment is capable between the jaws, which are both within the circle described by the head, and the object grasped between the jaws is brought very near to the side studs-a position where the strain is best resisted, which could not be done were a pivot passed through the head, as the slot would have to be above the pivot or the pivot below and at some distance from the slot. The slot could not in this case be central without pivoting The head eccentrically.

The outer edge of head B is toothed or scrrated for being engaged by the ends of dogs or pawls c c, which serve to hold the head securely in place as adjusted. These dogs are pivoted in slotted shank A on pins ff, at opposite sides of the shank, and are pressed into contact with the head by a spring, 9. Their lower ends extend outside the shank or handle, so that either or both may be quickly and readily disconnected by the hand of the operator grasping the tool. This allows a quick adjustment of the head and re-engagemerit of the dogs.

In addition, for holding either dog out of contact, the cam h is provided within the shank A on an arbor, r, and between the dogs, so that when turned to one side or the other. by means of the projection 7.: on the outer end or the arbor the pawl at that side is disengaged and held so. This construction and arrangement renders the tool very convenient for use in all situations and under every possible contingency. At the same time the wrench is compact and strong in every part.

This tool is to be distinguished from rotary or pawl-and-ratchet wrenches.

l laving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a wrench, the rotary circular head 13, formed with the side studs, a, and fixed jaw 21, and provided with the slot 0, extending across and beyond the center, movable jaw 0, sliding vidod with a shoulder, (1?, bearing against therein, and the screw 4, swiveled within the slot in line with the centerof the head,for e ngaging the under side of said movable jaw, in combination with the handle A and mechanism, substantially as described, for holding the head in the desired position, as set,forth.

2. In a Wrench, the circular head B, formed with the side studs, a, and fixed jaw 12, and provided with the slot 0 and shoulder 0 screw (1, bearing in the end wall of the slot and pro shoulder 0 block d head d, and the sliding jaw 0, provided with a screw-threaded tongue meshing with the threads of the screw, sub- 15 stantially as set forth.
