Fig. 7 1s a perspective view of a nut that is The upper portions of the legs of strap 13 are associated with the movable jaw carrying strap. extended a short distance forwardly of the front Fig. 8 is a perspective view of a. modified form edges of the-lower portions of said legs in order to provide shoulders |3a which when the strap carrying the shank I6 and sliding jaw I1 is moved forward to its limit of movement, engage the sides of the upper rear portion of the fixed jaw H and thus, the lower portions of the legs of the strap are spaced apart from the lower portion of said jaw so as to eliminate any tendency of strains imparted to the sliding jaw to impart tilting movement to the strap I3 and t the fixed jaw II while the upper portions of the legs of said strap are in engagement with the upper portion of said fixed jaw.
Formed on the inner faces of the legs of strap I3 just below those portions of the legs that receive the hood I5 and rear portion of shank I6 are inwardly presented lugs 2| that co-operate to provide a bearing for the upper one of the legs I0 of the Wrench handle during the sliding movement of the strap upon said handle.
In order to reduce friction between the parts during sliding movement thereof and to provide clearance for dirt, congealed oil, grease, or the like, the curved faces of the lugs 2| that provide bearings for the upper member of the wrench handle are provided with longitudinally disposed grooves 22. Practically this same construction is employed at the lower end of the strap I3 for the lower member Ill of the handle, but instead of providing lugs such as 2|, the entire lower end of the yoke I3 is increased in thickness and the inner curved face of thickened portion which engages the lower leg of the handle is provided with longitudinally disposed grooves 23.
In the construction of the strap or yoke I3, I prefer to form the same from malleable cast metal in order to enable the legs of the strap to be spread apart during the assembly of the parts of the wrench and then by pressure forcing said legs into parallel arrangement before the rivet I4 is set and headed.
A trunnion 24 is formed on the rear end of a threaded rod that occupies a position between the legs III of the handle and said trunnion has bearing in that portion of the rod that connect the rear ends of the members III of the handle and the forward end of said threaded rod bears directly against the rear face of fixed jaw This screw rod is preferably formed in a single piece and has its forward portion provided with a buttress thread 26, the fiat face of which is rearwardly presented and the rear portion of said rod is provided with a double V thread 21.
In order to impart rotary motion to the screw rod, a nut 28 is mounted on that portion of said rod having the double V thread 21 and formed in'the top and bottom of said nut are grooves 29 for the reception of the members II] of the handle. The outer side faces of nut 28 are provided with vertically disposed ribs 30 or said surfaces may be milled or corrugated in order to enable the nut to be more firmly engaged by the thumb and fingers of the operators hand.
The double V thread 21 may be cut on the rear portion of the rod or, if desired, the rear portion of the rod when manufactured may be substantially diamond shape in cross section and then twisted so as to produce the double thread.
In order to transmit rotary motion of the threaded shaft to the strap I3 that carries the sliding jaw, a nut 3| is mounted on the portion of the rod having the buttress thread 26 and said nut being located between the members II] of the handle and between the sides of the strap I3. Formed in the top and bottom of this nut are grooves 32 for the accommodation of the members ID of the handle and formed in the faces of said grooves 32 are smaller grooves 33 which materially reduces the area of the bearing surfaces between the members I0 and the nut.
In order to retain the nut 3| in operative position between the side members of strap I3, lugs 34 are formed integral with and project inwardly from the inner faces of the side walls of the strap and said lugs engage in corresponding recesses 35 that are formed in the side faces of nut 3|.
In some instances, the nut 3| may be dispensed with and threads for the reception of the buttress thread 26 may be stamped or formed on the inner faces of the side walls of the strap I3.
As illustrated in Fig. 2, the straight shoulder on the buttress thread is rearwardly presented, which construction is particularly applicable in pipe wrenches, but for monkey wrenches the flat face or shoulder on the thread should be forwardly presented.
Further in some instances, it may be found desirable to form the double V thread on the opening through nut 28 and with grooves formed on the rear portion of the rotating rod, which arrangement is the reverse of that illustrated in Fig. 2.
In the manipulation of my improved wrench, the sliding or movable jaw I! may be quickly adjusted toward or away from fixed jaw II by engaging the nut 28 between the thumb and index finger and moving said nut along the members II] of the handle, thereby imparting quick rotary movement to the threaded shaft with the result that the buttress thread engaging nut 3| will move the latter, the yoke I3, together with hood I5, shank I6 and jaw II, lengthwise upon the handle so that the work may be received between the jaws II and I1.
The particularly advantageous features of my improved construction are, the quick acting adjustment of the movable jaw, the simplicity of manufacture and assembly of the entire wrench and particularly the strap or yoke that carries the sliding jaw and the grooving of the strap and the nut 3| so as to minimize friction of the sliding parts and the minimizing of tendency of clogging of the sliding parts due to accumulations of rust, dirt, congealed grease, oil, and the like.
Thus it will be seen that I have provided a wrench that is relatively simple in construction, inexpensive of manufacture and very effective in performing the functions for which it is intended.
In my improved wrench, it is to be noted that the U-shaped strap or yoke which is formed of malleable metal is capable of being easily and quickly applied to the wrench handle and that the shank I6 that carries the movable jaw II is extended over the fixed jaw I I and connected to the upper portion of the yoke or strap, thereby eliminating time, labor and consequent expense that would otherwise be involved if the fixed jaw I I were extended upwardly and provided with a square hole for the reception of the shank and which construction is found in a number of wrenches of the type to which my invention relates.
In Fig. 8 I have illustrated a modified form of the nut that is utilized with the strap I3 that carries the movable jaw IT.
This form of nut is formed from a single piece of strap metal bent to form a substantially rec- 1. In a wrench, a handle comprising parallel I members integrally connected at one end, a jaw secured to the opposite end of said handle, a rod mounted for rotation on said handle and arranged between the parallel portions thereof, a quick acting thread formed on a portion of said rod, a nut arranged for sliding movement between the parallel portions of the handle and provided with a threaded opening for the reception of that portion of the rod having the quick acting thread, those portions of the nut that engage the parallel portions of the rod being provided with grooves that are disposed parallel with each other and with the axes of the parallel rods, a substantially U-shaped strap arranged for sliding movement on said handle, a shank pivotally connected to one end of said U-shaped strap, a jaw carried by said shank and disposed opposite the fixed jaw on said handle, a nut carried by said strap and disposed between the parallel portions of said handle and a thread formed on said rod in advance of said quick acting thread for engaging the nut carried by said strap.
2. A wrench as set forth in claim 1, with bearings formed on said strap for engaging the parallel portions of said handle and said bearings being provided with grooves that are disposed parallel to the axes of the parallel portions of said handle.
3. In a wrench, a handle comprising parallel members integrally connected at one end, a jaw mounted on the opposite ends of said parallel members, a rod mounted for rotation between said parallel members, the ends of which rod bear respectively on the integrally connected ends of said parallel members and upon the rear face of the jaw carried by said members, a thread formed on the forward portion of said rod, a quick acting thread formed on the rear portion of said rod, a yoke mounted for sliding movement on said parallel members, grooved bearings formed on said yoke for said parallel members the faces of which grooved bearings are provided with grooves that are disposed parallel with each other and parallel with the handle members, a hood secured to the upper end of said yoke, a
1 shank pivoted to the upper portion of said yoke and having its rear portion disposed within said hood, a jaw on the forward end of said shank, which jaw opposes the jaw carried by said parallel members, an expansive spring interposed between the rear portion of said shank and said hood, a nut mounted on that portion of the rod having the quick acting thread and having sliding engagement with the parallel members of the handle and the faces of said nut that have sliding engagement with the parallel members of the handle being provided with longitudinally disposed grooves that are parallel with each other and with the parallel members of the handle.
