ASSIGITOR TO THE CRESSINGTON CORPORATION, 15. CORPORATION OF NEW YORK.
W ENCH.
Application filed June 13, 1922, Serial No. 567,949. Renewed July 28, 1924.
To all whom it may concern.-
York, in the county of New York and State of New York, have invented new and useful Improvements in Wrenches, of
following is a specification.
This invention re wrenches, and par wrench wherein an adjustable jawis employed.
The primary object of the inv provide a wrench of such I movablejaw maybe easily and justed to the desired posltion held in such adjustment.
which the lates to improvements in icularly to that type of ormovable ention is to character that the quickly ad and firmly A further object of the invention is to provide a wrench of the character stated which embodies increased cooperative locking surfaces able :jaw, whereby the latter is between the shank and movand positivelyagainst any movement whatever when the saldrnovable aw has once been adjusted and moved to lo ,tion
cking posi-v wrench ismdicated at 7 and 18 carried by a Affurther object of the invention is to provide a wrench of the character stated of turn screws, adj ustdj ustingor of amore or less featured by the lack mg levers, springs, mamtammg mechanism and other a complex or cumbersome construction heretofore, used in similar dev-icesfor creating or maintaining-the adjustment of the mov able jaw; the invention herein contemplated. capable of being released from engagement with thereon by providing a movable jaw instantl y the shank; so as to be slid freely the hand of the operator when required,
and which, after the adjustment has been,
made, may be locked rigidly to the said shank, in a simple manner.
.A. further 7 and particular obj ect of the invention isto provide a wrench ofthatcharportion thereofis acter wherein'the shank provided with a number of teeth or serrations of the slidable head, the shank the wrench being so serrations may be readily cut to be engaged with corresp'ondingteeth it portion of constructed that the or formed upon agreat quantity of such shanks at a single operation of the toothcutting machine.
With these and other objects inview, the. invention. consists of the features of con-.
. struetion, combination and 'arna ngement of hereinafter fully described and reference being had to the accomwh1ch:
parts, claimed, panying drawing, in
Figure l is a side elevation, parts broken away, of a wrench constructed in accordance with the invention;
Fig. 2 is a rear elevation o wrench;
Fig. 3 is a side elevation of the improved f the improved .Wrench and body 7' of abreadth or thickness equal to that of the shank 5, said body-having spaced strap portions8 to extend around or embrace the shank to permit sliding movement of the head or jaw 7 longitudinally of the shank but to prevent the said adjustable head becoming detached from the shank. The body 7 and strap portions 8 so embrace the shankas to permit of slight lateral move ment of the head or jaw portion 7 relative. to the said shank, whereby the inneraor shank engaging surface of the said head may be moved outof contact with thesaid shankat the proper times;
The adjacent or cooperating gshank and slidable head faces are toothed or serrated as at 9, so that when thesaid faces are engaged with each other the teethwwillbe interlocked and the shankand-slidablehead against movement longitudinally of the shank but capable of moving laterally there in. This bar when moved outwardly of the channel 11, engages the strap portions 8 of jaw and causes the latter to move to such extent that the inner or serrated face thereof contacts with the toothed face of the shank 5, whereby the cooperating teeth of said elements will be interlocked. When the block 11 is withdrawn or moved inwardly of the channel 10, the head 7 is released and may move so as to withdraw its teeth from engagement with the t eth of shank 5. The means employed for controlling the movements of the block or bar 11 includes a locking strip 12 disposed in the base of the channel and underlying the block or bar 11. This locking strip is provided at spaced in tervals upon its outer edge with teeth 13 beveled or inclined on one edge as shown, which teeth are disposed within notches 14 similarly shaped in the adjacent edge of the block or bar 11. The block or bar 11 is provided at its extremities with laterally disposed slots 15, through which studs or pins 16 project; the said pins or studs being carried by the shank 5 and extending through the channel 10 therein. The inner end of the locking strip 12 has an outwardly extended operating finger 17, the outer edge of which protrudes slightly beyond the rear face of the shank 5 and may be roughened or milled to enable the thumb or finger of the wrench operator to grip and operate the same. The locking strip 12 carries a laterally disposed pin 18 extending loosely through a slot 19 in the shank 5, the said slot being disposed longitudinally of the shank to permit of limited movement of the said strip longitudinally of the shank.
From the foregoing it is apparent that I have provided a wrench of extremely simple construction and yet which may be quickly and easily adjusted so as to lit the element or surface with which it is intended that the jaws engage. This adjustment may be easily accomplished by moving the jaw 7 with the hand after withdrawal of the block or bar 11 from engagement with the rearwardly extending straps S of the said head. As soon as the adjustment has been made, the locking strip 12 will be withdrawn so as to cause the block or bar 11 to move rearwardly and draw the head 7 so that its teeth will interlock with the teeth 9 of the shank. LlllS act on being created by applying rearward movement to the finger 17 of the locking strip and causing the projections 13 to ride against the inclined surfaces of the notches 14 and force the block or'bar 11 in an outward direction. Movement of the locking strip in the reverse direction will at once release the block or bar 11 and permit of the same being withdrawn from engagement with the straps 8.
It will be noted that the shank is of even thickness throughout its length, and by reason of this fact a great number of such shanks, prior to the application of heads 7 thereto, may be assembled in a tooth cutting machine and properly alined and held ticrein so that a single operation of the cutting mechanism will cause a. great number of said shanks to be toothed.
It will be noted that the body 7 carrying the fixed jaw 7, and the spaced straps 8 of said body, are arranged in rear of the transverse plane of the jaw 7, the straps 8 thus being wholly out of alinement with the toothed face of said'jaw. This allows the teeth of the jaw to be out thereinto in its process of manufacture without interference from the straps and also allows a number of such jaws to be assembled and held in a tooth cutting machine, so that the teeth of a plurality of jaws may be out in a single operation. Furthermore, such arrangement of the body 7 and spaced straps 8 gives a wide range of supporting surface for the movable aw on the shank, ensuring its firm retention in adjusted position, and the spaced straps obviate any liability of tilting or canting of the jaw on the shank. By placing the teeth on a jaw constructed and mounted as described, instead of placing the teeth on the inner surfaces of the straps, greater ease of manufacture is provided for in addition to the above-stated advantages.
The handle 20 of the wrench includes a tubular member as shown having a slot or notch 21 at its inner end to receive the out wardly extending finger 17 of locking strip 12, and this tubular member is held in position upon the handle portion of the shank by means of studs or rivets 22 passing through the shank and the tubular handle.
.Vhile the above is a description of the in vention in its preferred embodiment, it is to be understood that various changes in the construction and arrangement of parts may be resorted to, if desired, without departing from the spiritof the invent-ion as defined by the claims. I
Having thus fully described my invention, I claim:
1. In a wrench, the combination of a shank provided with looking teeth and a fixed jaw along one of its longitudinal edges and provided in its opposite edge with a channel, a movable jaw having a strap portion slidably engaging said shank, said movable jaw having teeth to engage the teeth of the shank and said strap portion being movable laterally of the shank to permit the teeth of the shank and movable jaw to be thrown into and out of engagement with each other, a locking bar movable laterally of the channel and having a slot and pin connection at each end with the shank to permit of such movement, said her having l'dO an outer plane face for engagement with the strap of the movable jaw and having an inner face notched to provide a series of spaced inclined surfaces and stop shoulders, a locking strip slidably disposed in the channel between said bar and the bottom of the channel and having its outer surface provided with projections having inclined surfaces and stop shoulders for cooperation with the inclined surfaces and stop shoulders of the locking bar, and a finger-piece projecting laterally beyond the shank at the rear end of said locking strip, said fingerpiece having a sliding slot and pin connection with the shank.
2. In a wrench, a shank having parallel longitudinal: edges, teeth on one of said edges, the said shank having a longitudi nally disposed channel in its rear edge, a
20 bar disposed within said channel and spaced from the base thereof, pins in said shank at the ends of said bar, the said bar in its ends having laterally disposed slots receiving said pins, the inner face of said bar having notches with inclined walls, a locking strip underlying said bar, projections on said strip extending into the notches of said bar, inclined walls on said projections cooperating with the similarly constructed walls of said recesses, a finger at one end of said strip projecting beyond the rear surface of said shank, means for maintaining said locking strip in position within said channel, a jaw slidable upon said shank and having teeth to interengage with the teeth of said shank, straps embracing said shank, and the said straps extending around the outer edge of said block.
In testimony whereof I afiix my signature.
GRANT GREEN.
