Specification of Letters Patent.
Patented Nov. 1, 1921.
Application filed September 20, 1920. Serial No. 411,486.
To all 10h 0m it may concern Be it known that I, CHARLES L. STIDHAM, a citizen of the United States, residing at Gravois Mills, in the county of Morgan and State of Missouri, have invented new and useful Improvements in renches, of which the following is a specification.
My present invention has reference to improvements in wrenches.
The object is the construction of a wrench wherein the aws thereof may be quickly adjusted .without necessitating the employ ment of screws or the like, but wherein threaded means is employed for obtaining a positive engagement between the jaws and the article arranged therebetween.
A further object is the provision of a wrench in which the stationary head is provided with a toothed shank, and the movable jaw includes a carriage which is slidable on the shank. Carried by the movable jaw is a bolt. The bolt engages with the threaded bore of a block that has a toothed face to engage with the teeth of the shank, the said block being also arranged for swinging movement on the screw so that the teeth thereof will be brought out of engagement with the teeth of the shank and the movable jaw may be freely slid on the shank of the stationary jaw, while means is provided for holding the tooth of the block in engagement with the teeth of the stationary jaw.
A further object is the construction of a wrench which may be employed either for engaging square or rectangular elements or round elements such as pipes or bars, and in which the construction is comparatively simple, but strong and thoroughly eflicient in use.
The foregoing, and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative arrangement of parts, such as is disclosed by the drawings.
In the drawings Figure 1 is an elevation of a wrench constructed in accordance with this invention.
Fig. 2 is a similar view but showing the block swung angularly of the carriage of the movable jaw to permit of the quick adjust ment of the movable jaw with respect to the stationary jaw.
Fig. 4 is a longitudinal sectional View ap- 4 which serve as suction devices to permit of a more effective gripping of the tool.
The active face of the jaw 3 is toothed, as at 11.
Arranged for slidable movement on the shank 2 is the carriage 12 provided with a jaw 13. The jaw 13 has its active face provided with a pocket 14 in which is seated the rectangular shank 15 of a movable auxiliary jaw 16. The shank 15 is provided with an elongated slot which receives therethrough a pintle 17 that passes transversely through the jaw 13. The opposed ends of the shank are engaged by springs 18 which also engage with the end walls of the pocket. The active face of the auxiliary jaw 16 is arranged at an opposite pitch to the angular active face of the jaw 3, and the said face of the auxiliary jaw 16 is toothed or serrated. It is, of course, to be understood that the auxiliary jaw is removable and is employed only when the device is used as a pipe wrench.
The carriage 12 has its outer end formed with a yoke 19 and one of the side walls, 20, between the yoke and the inner wall of the jaw portion of the carriage is projected above the connecting portion between the said jaw and yoke, a distance approximately equaling or slightly in excess of the length of the teeth 21 on the shank 2 of the stationary jaw 3.
Having its ends arranged for rotatable movement, but prevented from longitudinal movement in the rear face of the jaw and in the yoke 19 is a screw 22. The reduced end of the screw, indicated by the numeral 23, which projects through the yoke has its outer end provided with a milled head 24:. On the screw there is a block 25. The block has a threaded bore which is engaged by the threads of the screw and has its side faces provided with projections which have their outer portions milled or roughened, as at 26. The block 25 is provided with teeth 27 that are designed, when the block is swung on thescrew to engage with the teeth of the shank 2. The outer and rounded face of the block is provided with a longitudinal groove 28. Secured to the rear and reduced portion of the movable jaw is a spring finger 29 that is designed to be received in the grocve 28 to hold the block against movement and the teeth thereof in engagement with the teeth of the shank. By operating the milled head of the screw, the same may be turned to obtain a minute adjustment between the stationary and movable jaws. For a quick adjustment between the jaws, the block is swung upon the screw to bring the teeth thereof out of engagement with the teeth of the shank and the carriage of the movable jaw is moved longitudinally toward the stationary jaw. WVhen the object is gripped therebetween, the block is again turned to bring its teeth to engagement with the teeth of the same, but the screw operates to cause the jaws to positively engage with the obstacle therebetween.
It is thought that the foregoing description, when taken in connection with the drawings will fully set forth the construction and advantages of the improvement without further detail description.
Having thus described the invention, what I claim is A wrench including a toothed stationary jaw having a toothed shank, a movable jaw having a carriage slidable on the shank, a spring influenced toothed auxiliary jaw arranged for limited movement on the active face of the movable jaw, a headed screw carried by the carriage, a toothed block having a threaded bore which is engaged by the screw and the teeth of the said block designed to engage with the teeth of the'shank, and spring means engaging the block for holding the same in engagement with the teeth of the shank, said block being susceptible to a swinging movement on the screw.
In testimony whereof I aflix my signature.
CHARLES L. STIDHAM.
