i ,ociosa Specification of Letters Patent.

atent'ed June 10, 1913.

Application filed September 10, 1912. Serial No. 719,568.

To all 207mm, t may concern:

Be it known that I, lnnononn C. Doni:- nAiv'r, a citizen of the United States, and a resident ot' New Orleans, in the parish o't Orleans and State otl Louisiana, have invented a new and Improved Monkey l/Vrench, of which the following is a full, clear, and exact description.

My invention has for its main object to produce a wrench having improved means it'or permitting a quick adjustment; ot the movable jaw.

A :further object ot' the invention is to provide in connection with the means jlio. adjusting the movable jaw, an improved latch device .'t'or holding the movable jaw in the adjusted position.

The invention will be particularly de scribed in the specific description hereinafter to be given.

Reference is to be had to the accompanying drawings forming a part oit this specilication, in which similar characters ot' ret'erence indicate corresponding parts in all the views.

Figure 1 is a perspective view of a wrench embodying my invention; Fig. 2 is a longitudinal vertical section of the movable jaw in the locked position; and Fig. 3 is a similar view with the parts in the position they assume when the movable jaw is released.

In constructing a wrench in accordance with my invention, a fixed jaw 10 is provided on a hollow handle 1l, and a jaw 12 is slidably mounted on the handle, 'for movement toward and from the fixed jaw. A locking bar 13 is pivoted as at 14, within the hollow handle adjacent to the iixed jaw and extends rearwardly the distance it is desired to slide the movable jaw. Suitable interengaging projections are provided on the movable jaw and on the locking bar 1?), there being in the present instance teeth 15 on the locking bar and mating teeth or projections 1G on the movable jaw.

The locking bar 13 is adapted to rock toward and from the movable jaw, to and intei-lock therewith. To move said locking bar to the outer position, a slide 17 is provided having a head 18 formed with a wedge-shaped or beveled end 1t), the slide furthermore having between the body and the head 1S thereof, a reduced portion 20, which passes through a guide piece 21, which forms an abutment for the front end of a compression spring 22, the opposite end olE which abats against a shoulder 23 on the slide 17. The tendency oli the` spring is to return the slide to the rcarmost position with the head t8 thereo't out otE engagement with the locking bar 1:5. 'l`he rear end otE the slide 17 has a head 2l adapted to bring` up against the rear end ot the handle 1l, tor limiting the inward movement et the slide. lVithin the handle llA also, and ranging alongside the slide '17 is a latch bar 25, `pivoted between its ends, as at 2G, and extending 'forwardly to a point adjacent; to the rear end ot the locking bar 13, there being a plate spring 2U carried by the 't1-ont end o't" the latch bar and bearing against the rear end ot the locking bar. Near the rear end the latch 25 is recessed, as at 27, which permits a rocking ot the latch toward the adjacent side ojt" the handle 1l. At the oppositie side the latch 25 has a projection 28 adapted to engage the rear end of the slide 17.

In operation, when it is desired to shitt the position ot the movable jaw from that shown in Fig. 2 to a jiosition nearer to or farther 'from the fixed jaw, the latch 25 is rocked to the position shown in llig. 3, and the slide 17 will then be moved by the action ot its spring rtarwardly ot.l the locking bar, by reason olE which the spring 2G will rock the locking bar inward on its pivot 'lt out of engagement with the movable jaw, and the latter is now vlree to be moved itor ward or back of the handle 1l. The head 24 is slotted as at S0, to ata'zommodate the rear end ot' the latch bar 25. To again lock the mo 'able jaw in adjusted position the slide 17 is moved :forwardly to cause the head 1S to rock the locking bar 13 outwardly against the tension ol. the spring 2G and into engagement with the movable jaw. The forcing out ot' the locking bar places the spring 2b under tension, and when the slide .17 has reached the :forward position, as in Fig. 2, said spring will have rocked the latch 25 to a position to bring the projection 2S in the rear ot the slide 17, thus holdingl the parts Ain locked adjustment. The inner side oi the latch 25 in the torni shown, has a notch 2t) to receive the end ot: the guide piece 21.

It will be understood that the illustrated example is merely given as a simple practical emlimdiment ot my invention, and I do not confine mysel'l to the exact, :l'form of construction illustrated.

Ilaving thns described my invention, I

claim as new and desire to secure by Letters Patent z- 1. A Wrench, comprising jaws, one of which is movable toward and from the other, a locking device for the movable jaw, an actuating member for the locking device, a latch for the actuating member, and a spring on the latch for engagement with the locking device for throwing the latch.

2. A Wrench, comprising jaws, one of which is movable toward and from the other, a locking device for the movable jaw, means for moving the locking device into engagement With the movable jai'; a latch for holding the parts in adjusted position, and spring means normally tending to move the locking device out of locking position and to move the latch into the latchng position.

3. A Wrench, comprising aWs, one of which is movable toward and from the other, a locking device, means for moving the locking device out of engagement With the movable jaw, and latching means operable by the locking device to hold the parts in the adjusted position.

il. A wrench, comprising a handle having a iixed jaw, a second aw slidable on the handle, a locking bar pivotally mounted Within the handle to rock toward and from the movable jaw, said movable jaw and said locking bar having teeth adapted for interengagement, a slide movable in the handle, said slide having a head at the rear end, a compression spring surrounding the slide intermediate its ends, a guide piece in the handle through Which the slide extends and against which the spring abuts at one end, said spring abutting its opposite end against the slide, a latch bar ranging alongside the slide within the handle, and pivoted to rock, said latch having a projection at its rear end to engage the head of the slide, the latch bar furthermore having a notch to accommodate the mentioned guide piece, and a plate spring carried by the forward end of the 'latch bar and bearing against the rear end of the locking bar.

n testimony whereof l have signed my name to this specification in the presence of two subscribing Witnesses.
