F. C. HACHENEY WRENCH Filed July 16 1925 Patented July 8, 1924.

UNITED STATES PATENT OFFICE.

FRANK C. HAGHENEY, OF JOHN DAY, OREGON.

WRENCH.

Application filed July 16,

To all whom it may concern:

Be it known that I, FRANK C. HAGHENEY, a citizen of the United States, residing at John Day, Grant County, in the State of Oregon, have invented certain new and useful Improvements in renches, of which the following is a specification.

This invention relates to wrenches and more particularly to an adjustable wrench to be made preferably of pocket size and adapted for use with bolts, nuts, grease cups, and other articles that require the use of the wrench. The main object of the invention is to provide a wrench that is easily and conveniently adjusted, and when once adjusted to remain so until readjusted, and in order to provide for the certain continued adjustment, there is arranged a locking means which prevents accidental relative longitudinal movement of the jaws of the wrench, while at the same time permitting a degree of pivotal movement of one jaw relative to the other.

The main object of the invention, and other objects that might hereinafter appear, are attained by the embodiment of the invention illustrated by the following description and the accompanying drawings forming a part of this specification.

In the drawings;

Fig. 1 isa side view in elevation'of the wrench as it appears in an adjusted position ready for use;

Fig. 2 is a view similar to Fig. 1, the movable jaw of the wrench being shown in section to entirely disclose the stationary jaw;

Fig. 3 is a view in elevation showing the position of the movable jaw in position for longitudinal movement relatively to the stationary jaw for adjusting the wrench;

Fig. 4 is a top plan view of the wrench showing the locking bar in dotted lines when in position to permit of the adjustment of the wrench, and in full lines when in position to prevent accidental longitudinal movement of the jaw;

Fig. 5 is a sectional view on the line 5 5 of Fig. 1;

Fig. 6 shows side and end views of the pivot pin; and

Fig. 7 is a detail plan view of the looking bar;

Fig. 8 is a detail section on the line 8-8 of Fig.1.

Referring to the drawings in detail, the reference character 10 designates the Shank 1923. Serial No. 651,926.

of the wrench having at one end thereof the ring handle 11, and at the other end, the head or jaw 12. The shank 10 is provided with a longitudinally arranged series of holes 13 connected by slots 14 for a purpose which will hereinafter appear.

A movable head or jaw 15 cooperates with the fixed head or jaw 12, the jaw 15 being provided with a shank 16 of channel shape, said shank 16 being mounted on the shank 10 and head 12 in slidable and pivotal relation thereto. An opening 17 is provided in each side of the channeled shank 16, said openings being in alignment, and a pivot pin, shown in detail. by Fig. 6 and designated generally by the reference character 18 passes through the opening 16 and through one of the holes 13 in accordance with the position of the shank 16 longitudinally of the shank 10, the spacing of the jaws 12 and 15 of the wrench being determined by the selection of the hole 13. v

The pivot pin is provided with a reduced flat portion 19 to permit the pin 18 to pass from hole to hole through the slots 14 when the pin is turned so that the flat sides of the portion 19 are parallel with the walls of the slots, as is obvious. When the shank 16 is in adjusted position, the wider sides of the reduced portion-will be disposed as shown more clearly by the dotted lines in Fig. 2, and longitudinal relative movement between the shanks 10 and 15 is thereby prevented.

The pin 18 is so disposed in the open ng 17 in the channeled shank as to be turned when the head 15 is turned. For instance, when the head 15 is in the position shown by Fig. 1, the wider sides of the portion 19 of the pin are disposed vertically, as shown by Fig. 2, and when the head 15 is in the position shown by Fig. 3 the wider sides of the pin portion 19 are disposed horizontally so that the head 15 and shank 16 may be adjusted longitudinally of the shank 10 in order to properly space the wrench jaws to suit the given work in hand. After the wrench jaws are properly spaced, the head 15 is returned to horizontal position and the pin 18 positioned in the hole 13 which thus acts as a bearing for the pin and prevents the longitudinal relative movement of the two main wrench parts, the heads 12 and 15.

From the description thus far given it is apparent that it would be desirable to provide a locking means to prevent the head 15 from turning accidentally so as to disturb use of the wrench.

the adjustment of the jaws. Accordingly, I have provided a locking means comprising a bar 20 pivoted on a pin 21 which ismounted in one side of the channeled. shank 16, as clearly shown by Fig. 5, the bar 20 being capable of moving through a slot 22 provide in the channeled shank 16. The bar 20 permits of a degree of movement of rotation be tween the heads and 12 as is desirable, but prevents the head 15 from turning sufliciently to be moved longitudinally of the stationary head 12 and shank 10. WVhen the bar is in position normally to prevent sufiicient turning of the head 15 to enable longitudinal movement thereof, it is obvious that accidental disturbance of adjustment of the jaws is prevented. Fig. l clearly shows the position of the fiat bar 20 to prevent undue turning of the shank 16, and in dotted lines in this figure is shown the position of the bar 20 when it is desired to move the head 15 to the position shown by Fig. 3 when it is desired to move the shank 16 longitudinally of the shank 10 for respacing the jaws of the wrench.

To enable the rapid adjustment of the wrench from hole to hole, there is provided near each hole 13 a groove or depression 23 with which cooperates a small rib 24 on the inside of the channeled shank portion. It will be easily understood that there are a plurality of such ribs for cooperation with the grooves 23.

The jaws 12 and 15 are provided with work gripping surfaces 25 and 26 which are preferably toothed and which. incline at ditl'erent angles to permit of fine adjustments of the relatively movable parts so that the aws may accurately fit any work to which the Wrench may be applied.

From the preceding description it is ap parent that I have provided an adjustable wrench that may be securely locked in adjusted position so that there can be no longit udinal movement of the movable aw while at the same time normal turning movement of the movable jaw is permitted and limited to the desired extent. The means for locking the wrench in adjusted positionis exceedingly simple in'both construction and 'OPGl'iiflOll and permits of the rapid and aceurate'adjustment of the wrench for dilferent kinds of work. Other advantages of the particular construction will 'be apparent from the description and from the practical 'f 'VVhile' Ihave shown the preferred embodiment of the invention, it is to be underonly, the invention is not to be considered as limited thereto except within the scope of the appended. claims.

Having thus described my invention, which I claim and desire to secure by Letters Patent of the United States is:

l. A wrench comprisinga stationary memher having a shank portion provided with a series of longitudinally spaced holes connected together, by slots, a movable member having a channeled shank slidably positioned on said stationary shank and provided with aligned openings in the sides thereof, a pivot pin passing through said aligned openings and positioned in a predetermined hole in the stationary shank, said pivot pin having a reduced portion to permit of its passing through said slots from hole to hole When the wrench is to be adjusted, and a locking bar pivotally connected to said movable member and cooperating with said stationary member to prevent accidental longitudinal movement of the movable member.

2. An adjustable wrench comprising a- .stationary member having a shank provided with holes longitudinally spaced, adjacent holes being connected by slots, a movable member having a channeled shank in slidable relation with said stationary shank and provided with aligned holes in the sides thereof, a pivot pin passing through said holes and positioned in a predetermined hole of the stationary shank, said pivot pin having a reduced portion adapted to be brought into alignment with a slot between adjacent holes wlu-nreby the movable member maybe moved from hole to hole for adjustment longitudinally of the stationary shank, and a bar pivotally connected to said movable member and cooperating with said stationary member to limit the pivotal movement. of the tormer with respect to the latter.

3. A wrench having a stationary member, a movable member provided with aslot slid ably and pivotally mounted onsaid stationary member, and means for limiting the pivotal movement of the movable member comprising abar pivoted within said slot in the movable member and movable into alignment with the stationary member and out of alignment therewith transversely through said slot.

4-. A wrench comprising a stationary member, a movable member, means for pivotally connecting said members together, said movable member having a slot therein, a pin mounted in saidmovable inember-and'passing throughsaid slot, and a bar journalled on said pin and swingable through said slot transversely of said movable member'for controlling the pivotal movement between the stationary and movable members,

In witness whereof, I hereunto afiix my signature. 1
