PIPE-WRENCH.
Specification of Letters Patent.
Patented May 23, 1916.
Application filed November 17, 1915. Serial No. 61,956. i
To all whom it may concern:
Be it known that I, BENJAMIN F. ADAMs, a citizen of theUnited States, residing at Stratford, in the county of Sherman and State of Texas, have invented certain new and useful Improvements in Piperenches, of which the following is a specification, reference being had to the accompanying drawings.
My invention relates to wrenches, and particularly to the type of wrench illustrated in my prior Patent No. 1,095,616, granted to me May 5, 1914, the particular object of the invention being to improve upon my prior patent by the provision of means whereby the movable jaw shall be adjustable along the length of the wrench shank so as to thereby adjust the device to d-iiferent sizes of work;
A further object of the invention is to improve upon the construction illustrated in my prior patent by providing means whereby it may be adjusted quickly.
Other objects will appear in the course of i the following description.
' My invention is illustrated in the accompanying drawings, wherein:
Figure 1 is an elevation of my improved wrench, some of the parts being in section; Fig. 2 is a top plan viewyFig. '3 is a perspective view of the movable jaw; Fig. l is a perspective view of the spring; Fig. 5 is a perspective view of the latch.
Referring to these figures, designates the handle of a wrench which at one end is formed to provide the hook-shaped jaw 11, the inner face of which is provided with teeth 12. This shank is longitudinally slotted, as at 13, and upon one edge of the shank is provided with the ratchet teeth 14:.
Pivotally mounted upon the shank is a movable jaw designated generally 15. This jaw is transversely U-shaped in configuration and embraces the shank'lO and is held to the shank by a pivot bolt 16 which passes through the slot 13. The extremity of the jaw is curved and formed with teeth 17 'coacting with the teeth of the fixed jaw. Also pivotally mounted upon the pivot bolt 16 is a latch member illustrated in detail in Fig. 5 and designated generally 18. This latch member comprises a body or solid portion 19 having laterally disposed arms 20 and laterally disposed arms 21 extending at right angles to the arms20. The arms 20 are laterally offset at their extremities so that they can pass over the rearwardly exwith the bolt 16.
Slidably. mounted upon the shank 10 is a spring 22. This spring extends approximately parallel to the shank and at one extremity is formed with the T-shaped head 23. The opposite end of the spring is angularly bent and formed with a collar 24 which embraces the shank 10 and is movable therealong. The shank 10 is formed w th outwardly projecting ears 25 and a pm 26 extends across these cars and bears frictionally against the spring 22. This provides for shifting the spring in accord ance with the adjustment of the movable aw. The pressure on the movable jaw when the wrench is being used causes the spring 22 to bind against the pin 26 and upon the shank 10 so as to hold the spring in its adjusted position. But when the wrench is not in use the spring may be readily shifted by hand along the extent of the shank. As will be noted from Fig. 1, the portion 19 or body of the latch 18 is formed to provide a tooth 27 which is engageable with any one of the notches or teeth 14, so as to hold the latch in its adjusted position.
In the practical use of my invention the latch 18 is released from its engagement with the teeth 14: and shifted longitudinally, which will shift the movable jaw toward or from the fixed jaw. The latch is then reengaged with the corresponding notch or tooth 14 and the fixed jaw is held from further movement. At the same time the spring 22 is caused to longitudinally slide so as to bring the spring in proper position with relation to the movable jaw. This improvement renders my wrench readily adjustable to various sizes of work and this adjustment is very simple and may be very quickly made. I have found it extremely effective in practice, and furthermore, the wrench may be cheaply made and sold.
Having described the invention, what I claim is:
1. A wrench of the character described including a shank having a fixed jaw and being longitudinally slotted, a jaw having a pivot member passing through the slot of the shank whereby the jaw is rendered lon gitudinally adjustable along the shank, means connected with the pivot of the movable for holding it in adjusted position 'but permitting free movement of the jaw on its pivot, and a spring bearing against the movable jaw and urging it toward the shank.
2. A. wrench of the character described including a shank having a fixed jaw and .beinglongitudinally slotted, a jaw having 3. A wrench of the character described including a shank having at one end afixed jawand being longitudinally slotted, a pivot pin passing through the slot of the shank,
a movable jaw pivotally mounted upon said pivot pin and thereby mounted for. oscillationand longitudinal adjustment, a latch mountedupon the pivot pin and operatively engaging with the shank to hold the pivot pin in adjusted position, and a spring longitudinally adjustable upon the shank and having its free end engaging with the. said movable jaw to urge it toward the shank.
4. A wrench or" the character described including a shank longitudinally slotted, intermediate its ends and having'a fixed jaw formed thereon at one. end, a bifurcated.
movable embracing the shank, a pivot pin passing through said jaw and through the slot, a latching member havingarms at one end embracing the shank and the piv- V otal end of the movable jaw and connected I V to the pivot thereof, the other 'end of the latch member being bifurcated to embrace the shank, a tooth formedupon said'latch member, the shankbeing formed with teeth with which said latching tooth is adapted to engage to hold the movable jaw in adjusted position, and a longitudinally adjustable spring mounted upon the shank and havmg its free end engaging w th said movable aw -to urge it toward'the shank- In testimony whereof I hereunto affix my signature in the presence of two witnesses. BENJAMIN'F. ADAMS.
