Application filed March 15, 1915. Serial No. 14,497. v
To all whom c't mag concern Be it known that I, FRANK KooNs, a citizen of the United States, residing at Grooville, in'the county of Sullivan and State of New York, have'invented a new and useful Wrench, of which the following is a specification. I j
The present invention appertains to wrenches, and aims to provide a novel and improved wrench adapted particularly for use as a pipe wrench, and having unique means for mounting, adjusting and controlling the pivoted jaw. v
Another object ofthe invention is the provision of a wrench embodying a novel as semblage and arrangement of'the component parts, whereby the utility and efficiency of the wrench is enhanced, and in order that the structure may be comparatively simple and inexpensive.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
The invention is illustrated in the accompanying drawing, wherein Figure 1 is a side elevation of the improved wrench. Fig. 2 is a similar view,
with parts shown in section. Figs. 3 and 4'. are cross sections, taken on the lines 3-3 and H, respectively, of Fig. 1.
The present wrench embodies a shank or stock 1 having an angularly extending toothed stationary jaw 2 at one end, and a suitable handle 3 at its other end. The shank 1 is provided with screw threads 4: extending from the handle 3, and an adjusting nut 5 is threaded upon the threaded portion of; the shank for longitudinal ad justment, and is provided with an annular or circumferential grooveii for theengagement of the slide 7 which carries the movable and pivoted jaw. This slide 7 embodies a doubled sheet metal plate 8 having the intermediate portion thereof cut out, as at 9, and a longitudinal block 10 secured between the side'portions of the plate 9 by means of rivets or other securing elements 11 engaged through the plate 8 and block 10. The slide 7 embraces the shank 1, the bend of the plate 8 resting slidably against one edge of the shank, and the longitudinal elongated block 10 resting against the opposite edge of the shank. The slide 7 is adjusted by the nut 5, the inner end of the slide bearing against the respective face of the nut, and the inner end of the block 10 having a hook 12 engaging the groove 6 of the nut, whereby when the nut is rotated, the slide will be constrained to move longitudinallywith the nut either toward or away from the stationary or fixed jaw 2. The inner ends of both the plate 8 and blocklO bear against the nut in order that the slide 7 may be effectively forced toward the jaw 2 when the nut is threaded outwardly. When the nut is threaded inwardly, the hook 12 in engaging the groove of the nut, will draw the slide 7 away from the stationary aw 2.
The movableand pivotedjaw 13 is pivoted between the outer end portions of the side members of the plate 8, by means of a rivet or other pivot element 14: engaged through the side members of the plate 8 and through the jaw 13, the outer end of the block 10 terminating short of the outer end of the plate 8 to accommodate the jaw 13. The j aw 13 is provided with an arcuate toothed face 15 cooperating with and complementing the toothed face of the stationary jaw 2 which is arranged at right angles with the shank 1. The teeth of the jaws preferably face inopposite directions, whereby they may effectively grip the pipe or other object to provide a firm hold, as will be apparent.
The jaw 13 is provided with a rounded or curved portion 16 adjacent the shank 1, and with a straight shoulder or end17-normally abutting against the outer end'of the block 10. The outer end of the block 10 has a projecting wedge-shaped portion 18 ad acent the shank and projecting snugly between the shank and the rounded portion 16 of the jaw 13, whereby the rounded portion of the jaw will work snugly along the outer end of the block 10 when the jaw 13 is swung. The pivoted end of the jaw 13 is further provided with a tongue or projection 19 extending inwardly therefrom and overlapping the outer end portion of the block 10,-the tongue 19 normally bearing against the block when the jaw 13 is swung away from the shank 1.
The jaw 13 is spring pressed away from the shank 1, and to this end the edge portion of the jaw 13 adjacent the shank is provided with a recess or cavity 20 in which a coiled wire expansion spring 21 is seated, and the spring 21 bears against the respective edge of the shank 1. This spring 21 is carried by the jaw 13 and slides along the shank when the slide 7 is moved longitudinally along the shank, whereby the spring 21 will be active for moving the jaw 13 away from the shank at any position of the parts.
As a means for holding the jaw 13 at various positions, and for limiting the movement of the jaw 13 away from the shank 1, a member or plate 22 is slidable along that side of the block 10 remote from the shank 1, and is provided with a wedge-shaped outer end 23 adjacent and cooperating with the tongue 19 of the pivoted jaw 13. The member 22 has a longitudinal slot 24 through which a clamping screw 25 is engaged, the screw 25 being threaded into the block 10, and being arranged to clamp the member 22 at various longitudinal positions. The wedge-shaped end 23 of the member 22 is arranged to wedge or project between the block 10 and tongue 19 when the member 22 is slid outwardly, and for the purposes which will hereinafter more fully appear.
In use, it is evident that the movable jaw 13 may be readily adjusted to and from the stationary jaw 2, by rotating the nut 5, to cause it to travel along the shank 1, and to move the slide 7 accordingly. When the jaws 2 and 13 are applied to a pipe or other object which is to be given a torsional strain, and when the shank 1 is swung or moved properly (counter clockwise as seen in Fig. 1), the jaw 13 will swing toward the shank 1, and this will cause the pipe or object to be tightly gripped, whereby it may be forcibly rotated for the desired purpose. The spring 21 normally throws the jaw 13 away from the shank 1, but allows the jaw 13 to yield or swing toward the shank when necessary. Themovement of the jaw 13 is limited when the free portion of the jaw strikes the shank,
- and the movement of the jaw 13 away from the shank is limited when the end 17 and tongue 19 of the jaw 13 strike the block 10.
When it is desired to hold the jaw 13 stationary, it-may be held against the shank 1, by sliding the member 22 outwardly so that its wedge-shaped end 23 wedges tightly between the tongue 19 and block 10, to prevent the jaw 13 from swinging away from the shank. The wrench may thus be employed as an ordinary wrench for rotating nuts, and other articles, and the jaw 13 will be prevented from oscillating or swinging, although it may be adjusted longitudinally as before. The member 22 also provides means whereby the oscillation of the jaw 13 may be restricted or limited to various degrees. Thus by adjusting the member 22 so that its wedge-shaped end 23 projects partially between the tongue 19 and block 10, the wedge-shaped end 23 of the member 22 will prevent the tongue 19 from swinging against the block 10, and this will limit the swinging movement of the jaw 13 away from the shank 1. Consequently, by adjusting the member 22, the oscillatory movement of the jaw 13 may be regulated as desired, this being essential in some cases when it is not desirable to allow the jaw 13 to swing the full amount. Thus, when the wrench is employed upon light or weak pipes, the excessive swinging movement of the jaw 13 would be liable to crush or indent the pipe, which would be objectionable, but when the swinging movement of the jaw 13 is limited, this objection is avoided, without sacrificing the gripping action of the jaws upon the pipe or object. The edges of the plate 8 are preferably projected beyond the block 10 to provide means for receiving therebetween, the tongue 19 and member 22, so that the said parts will be protected ordinarily, as will be apparent by reference to the drawmg.
Having thus described the invention, what is claimed as new is:
1. In a wrench, a shank, a slide movable thereon, a jaw pivoted to the slide to swing to and from the shank, and an adjustable member carried by the slide, the adjustable member having a wedge-shaped portion, and the jaw having a portion cooperating with said wedgeshaped portion, whereby the swinging movement of said jaw may be limited to various degrees.
2.'In a wrench, a shank, a slide movable thereon, a jaw pivoted to the slide to swing to and from the shank and having a project ing portion overlapping the slide, and an adjustable member carried by the slide and having a wedge-shaped portion to move between the slide and said projecting portion for limiting the swinging movement of said aw.
3. In a wrench, a shank, a slide movable thereon and comprising a doubled plate and a block secured between the side members thereof, the bend of the plate and block slidably engaging opposite portions of the shank, a jaw pivoted between the side members of the plate adjacent one end of the In testimony that I claim the foregoing as block and having a tongue overlapping the my own, I have hereto affiXed my signature block and to bear thereagainst when said in the presence of two witnesses.
