SPECIFICATION forming part of Letters Patent No. 451,024, dated April 28, 1891.
Application filed December 24,1890. Serial No. 375,675. (No model.)
T a/ZZ whom, it may concern.-
Be it known that I, AMBROSE B. OHADWICK, a citizen of the United States, residing at Pullman, in the county of Cook and State of lllinois, have invented certain new and useful Improvements in XVrenches, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
My invention has for its object to provide an improved wrench that shall be simple, cheap, and durable in construction, and that can be readily adapted for various purposes, andthe adjustment of which to permit the gripping of various objects can. be rapidly efiected. This object of invention I have accomplished by providing the various novel features of construction hereinafterdescribed,'illustrated in the accompanying drawings, and particularly pointed out in the claims at the end of this specification.
Figure 1 is a view in side elevation of a wrench embodying my improvements. Fig. 2 is a view in vertical longitudinal section, parts being shown in elevation. Fig. 3 is a view in transverse section on line 3 3 of Fig. 1. Fig. 4 is a view in transverse section on line 4 4: of Fig. 1.
A designates the body of the wrench, that will be provided with a handle a, conveniently attached thereto or formed in piece therewith.
The body A is preferably flattened on its opposite edges or provided with the screwthreads at, whereon is carried the threaded adjusting-nut B, that is held within the cutaway space 0 of the sliding block 0, thissliding block being held upon the body of the wrench in a manner permitting it to move thereon without turning.
To the end of the body A are conveniently attached the pivoted jawsD andD. By preference the jaw D is furnished with the plates or extensions d, and the jaw D is furnished in like manner with the overlapping plates cl, being of proper size to set over the plates (1 of the jaw D, and through the plates at and d of the jaws D and D passes the pivot-bolt E, that extends through a perforation in the end of the body A of the wrench and serves to securely hold the jaws in place, the ends of the bolt E being upset or headed ping-face of the jaw D is serrated or toothed,
as at (Z and bypreference the corresponding face of the jaw D is milled or roughened, so as to better enable the jaws to grip the object upon which the wrench is to be used.
My purpose in milling the face of the jaw D in the manner shown is to prevent the locking of the jaws upon the article held therein, which would be the case if each of the jaws were provided with serrations or teeth like the jaw D.
Each of the jaws D and D isfurnished with an extended rear portion (l and d, against the inner inclined face of which will'bear the beveled portion of the sliding block 0.
From the foregoing description it will be seen that when it is desired to adjust the pivot-jaws D and D of the wrench itis only necessary to turn the adjusting screw 13, thereby causing the block 0 to be shifted in either direction, and as the block 0 is thus shifted it will bear against theinclined faces of the rear portions of the jaws D and D, thereby causing these jaws to close to the desired extent. hen the sliding blockOis retracted by the turning of the thumb-screw B, the coiled spring F will open the jaws as the sliding block recedes from between the rear portions of the jaws. As the slide-block 0 serves to simultaneously operate both of the jaws D and D, it is obvious that a very quick adjustment of the jaws can be effected.
A very important feature of my invention is the employment of the sliding block 0, held upon the body A and operated by a screw-nut B, since by the use of a sliding block controlled by separate screw-nut no turning of the block is required, but a simple straight movement thereof against the face of the jaw is had. This feature of my invention, while especially adapted for a wrench having two pivoted jaws, as above indicated, could also be employed with advantage in connection with a wrench having a single pivot-j aw, since it is obvious that if one of the jawsfor example, the jaw Dwere formed in piece with the body of the wrench A, the rear end of such jaw D being omitted, the shifting of the pivoted jaw D could still be effected by the movement of the blocks 0 and screw-nut B. In other words, while I regard the employment of the two jaws as a very material advance, still I wish my invention, so far as the use of the sliding block and screw-nut are concerned, to be understood as applying also to wrenches in which a single pivoted jaw operated by such block and nut is employed.
In practice my invention has proved highly efficient, being adapted to a great variety of Work, and by its simplicity and durability and the ease with which it can be adjusted commending itself to those familiar with this class of devices.
Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is-
1. A wrench comprising a threaded body, two jaws at the end of said body, one at least of said jaws being pivoted to the body and provided with an extended rear portion, a slide-block mounted upon said body, and a screw-nut upon said body for shifting the slide-block to operate the jaw, substantially as described.
2. A wrench comprising a threaded body, two jaws at the end of said body, one at least of said jaws being pivoted to the body and provided with an extended rear portion, a slide block mounted upon said body and formed with a space to receive a screw-nut, and a screw-nut upon the body and within the space of the slide-block for shifting the slideblock: to operate the jaw, substantially as described.
A wrench comprising a threaded body having pivoted jaws at its end, a slide-block for forcing said jaws together, and a screwnut for shifting said slide-block, substantially as described.
4:. A wrench comprising a threaded body having pivoted jaws at its end, a slide-block for forcing said jaws together, a screw-nut for shifting said slide-block, and a spring for forcingsaid jaws apart, substantially as described.
5. A wrenclrcomprising a body A, having flattened sides and threaded portions and having pivoted jaws at its end, said jaws being formed with extended rear portions, a sliding block (3, mounted upon said body A and provided with a space a, and a screw-nut B, held within said sliding block C, substantially as described.
