ATTORNEYS J. A GILES. PIPE WRENCH.
(No Model.)
Patented Aug. 6, 1889..
V INV T I I fl-i UNITED STATES PATENT QFFICE.
JULIAN A. GILES, OF OSNVEGO, NEW YORK, ASSIGN OR TO OHAUNCEY C. PLACE, OF SAME PLACE.
PIPE-WRENCH.
SPECIFICATION forming part of Letters Patent No. 408,479, dated August 6, 1889.
Application filed April 1, 1889. Serial No. 305,573. (No model.)
To all whom it may concern.-
Be it known that I, JULIAN A. GILEs, of Oswego, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Pipe-Wrenches, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention relates to the class of pipewrenches which have one of the jaws integral with the handle and the other jaw connected to the handle by links pivoted thereto; and
- the invention consists in certain novel auxiliary devices employed in connection with said jaws, as hereinafter fully described, and specifically set forth in the claims.
In the accompanying drawings, Figure 1 is a side View of a pipe-wrench embodying my improvements, and showing the same in two of its operative positions. Fig. 2 is a top plan view of said wrench; and Fig. 3 is a longitudinal transverse section on line x 0, Fig. 2. i
L denotes the lever or handle of the wrench, which lever is formed at one end with the jaw j, and with an inclined bearing a. extending from the jaw rearward, for the purpose hereinafter explained. To opposite sides of the jaw-carrying end of the lever L, and preferably at the junction of said lever with its jaw, I pivot at one end links 2) b, to the opposite end of which is pivoted the jaw j. This latter jaw is formed withv a rearward extension c, and with a screw-threaded eye 6 in said extension, facing the inclined hearing a, hereinbefore referred to. In the screwthreaded eye 6 works a set-screw d, which rides on the inclined bearing a, and constitutes a stop for limiting the movement of the jaw j toits open position. Between the two jaws I interpose a spring 25, preferably of spiral form, and disposed with its axis parallel with the face of the jaw j, as illustrated in Fig. 3 of the drawings. Said spring serves to crowd the jaw j forward and into its open position. In order to limit the forward movement of the said jaw, I provide the fixed jawthe set-screw d is first adjusted to allow the jaws to open sufliciently to grasp the pipe, and after the jaws are placed in position to grip the pipe the lever l is swung in the direction indicated by an arrow in Fig. 1 of the drawings. The engagement of the teeth of the j aw j with the aforesaid pipe crowds said jaw rearward, and by the said movement the links '1) b are thrown into a rearwardly-inclined position, and thus reduce the distance between the two jaws, and at the same time the set-screw d is carried onto the raised end of the inclined bearing a, and thus causes the jaw j to grip the pipe with increased force, as indicated by dotted lines in Fig. 1 of the drawings. The jaws are caused to readily release their hold on the pipe when desired by merely reversing the movement of the lever Z, which allows the jaw j to spring forward again into its normal position, as presented by full lines in Fig. 1 of the drawings.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A pipe-wrench composed of a lever, a fixed jaw integral with one end of said lever, links pivoted at one end to opposite sides of the j aw-carrying end of the lever, a jaw pivoted to the opposite end of said links and formed with a rearward extension, a spring holding the latter jaw in its open position, and a stop between the aforesaid rearward extension and lever and adjustable in length to control the opening of the jaw, as set forth.
2. A pipe-wrench composed of a lever, a fixed jaw integral with one end of said lever, links pivoted to opposite sides of the jawcarrying end of the lever, a jaw pivoted to the opposite end of said links and formed with a rearward extension and with a screwthreaded eye in said extension and facing the lever, a spring holding the said jaw in its open position and crowding the same forward, a set-screw in said eye bearing on the lever, and stops on the fixed jaw in front of the links, substantially as described and shown.
3. The combination of the lever Z, formed at one end with the jawj, and with the inclined bearing to extending from said jaw IOC j, and with the inclined bearing a extending from the jaw rearward, the links Z) Z), pivoted at one end to opposite sides of the lever at its junction with the jaw, the jawj, pivoted to the opposite end of the links and formed I 5 with the rearward extension 0, and with the eye 6 in said extension facing the bearing a, the set-screw d in said eye the spring 15, crowding the jaw j forward and into its open position, and the stops f on the jawj in front 20 0f the links, all combined to operate substantially as set forth.
In testiinonywhereof I have hereunto signed my name this 25th day of March, 1889.
