WRENCH Fild'sept. Aso. 1924 Patented Mar. 24, 1925i.
UNITI-:D STATES NINxo srANovIc, or DUQUESNE, PENNSYLVANIA.
"WRENCH implication med .samenwer` 3o,"ie24. seriai No. 740,831.`
To all 'whom it may concern? Be it known that I, Nnvno SrANovio, a citizen of the United States of AmericaQresiding at Duquesne, in the county of Alle gheny and vState of Pennsylvania, have invented certain new andy useful Improvements in I/Vrenches, of which the following is a specification. j
My present invention relates generally to wrenches and more particularly to adjustable wrenches, my obj ect being the provision of a wrench of the type generally known as monkey-wrenches, which will be strong, durable and effective and which includes paralr lel clamping members or jaw supporting members and opposing jaws carried by said members, together with a handle to which the said clamping members are pivoted adjacent to one end and in laterally spaced relation whereby the jaws will automatically tighten when the wrench is applied in use.`
In the accompanying drawing which illustrates my present invention and forms a part of this specication,
Figure 1 is a side elevation;
Fig. 2 is a similar view, partly broken away in order to illustrate the effective posi* tion of the spring; and
Fig. 3 is a detail perspective view of the spring removed.
Referring now to these figures my present invention proposes a wrench wherein the rigid jaw 10 is in the form of an angular extension upon one end of a clamping member or jaw supporting shank 11, the adjustable jaw 12 being carried by a frame 13 which is slidable at one side on theshank 11 and which frame has an inner extension 111 spaced from its jaw 12, the latter of which thus opposes the rigid jaw 10. In the space between the movable jaw 12 and the extension 14 of the frame of this jaw is a milled rotatable sleeve 15 internally threaded to engage the threads of the screw shank 16 of the movable jaw, the latter of which pro? jects through an opening in the extension 14 of the movable jaw frame and is provided at its inner end with a head 17 disposed in laterally spaced alined relation with the inner end of the shank 11 as particularly seen in Fig. 2.
The outer end of screw shank 16 thus projects into the adjusting sleeve 15 to an extent variable according to the position of the movable jaw lrelative to the fixed jaw, the outer end of the adjusting sleeve rotating around the projecting head oli' aguide 'screw 152L which is threaded as particularly shown in Figure 2 into the movable jaw.
Moreover as particularly seen in Fig. 2 the head 17 of thefscrew shank and the adja-` cent innerl end of theshank 11 are disposed within the slotted outer end ol the handle 18, the slot of which is at 19. In this slot the head 17 and the inner end of the shank 11 are movably held by transverse pivot pins 20 and 21 and the inner squared ends of the head 17 and shank 11 are engaged by the outer lat portion 22 of a controlling spring whose ends are turned inwardly in spaced relation to the outer flat portion 22 and terminate in adjacent angular extensions 23 the latter of which are seated in an axial cavity 24C of the handle centrally of the base of its slot 19.V y j In this way the spring will be held seated within the base of the slot and the inner squared portions of the head 17 and shank l1 will by virtue of such engagement of the spring serve to clearly hold the two shanks 11 and 16 in parallel outstanding relation, both shanks being, however, free to yield in a slightly angular direction when the wrench is applied in use in orderthat when the handle 18 is grasped, the two jaws will automatically shift toward one another.
This it will be obvious takes place without prejudice to ready adjustment of the movable jaw by rotation of the milled sleeve 15 in one direction or the other depending upon whether the jaws are to beV shifted toward or away from one another and itbecomes quite apparent from this that the wrench as a whole is capable of ready, quick and convenient manipulation, will be especially effective and etlicient in use, and is of a strong durable nature.
I claim: j
1. A wrench-comprising a pair of opposing jaws, aw supporting members therefor disposed in parallel relation, of which the jaw of one supporting member is adjustable with respect thereto for adjustment toward and away 'from `the other'jaw` and a handle having a slot at one end in which the inner ends of the said jaw supporting members are pivotally mounted in laterally spaced and alined relation, the handle having a cavity centrally of the base of the slot, and a spring having side portions bent upon themselves and similarly engaging the inner ends of the being disposed in the slot of the handle and having inturned ends terminating in angular extensions between the said side portions seated in the said cavity.
2. A wrench consisting of a rigid shank having an angular jaw at its outer end, a movable jaw opposing the rigid jaw, a frame `in connection with which said movable jaw is formed, slidab-ly supported on the rigid shank and having an extension spaced from the movable jaw, an internally threaded and externally nurled sleeve in' said space, a supporting screw entering the movable jaw and arranged with its head within, and forming a bearing for, the outer end of said sleeve, a screw shank having its outer end movable through said extension and into the adjacent ends of the rigid shankand the screw shank are pivoted in laterally alined and spaced relation, and a spring in the slot of the handle engaging the inner ends of said yShanks for the purpose set forth.
