SPECIFICATION forming part of Letters Patent No. 663,161, dated December 4, 1900.
Application filed April 25, 1900.
T0 at whom it may concern.-
Be it known that I, JAMES FATKIN, a citizen of the United States, residing at Gulch, in the county'of Pitkin and State of Colorado, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to certain new and useful improvements in wrenches for pipes, rods, tubes, nuts, and the like.
In the accompanying drawings, Figure 1 is an edge view of a wrench embodying my invention. Fig. 2 is a side elevation thereof with a portion of the handle broken away and shows in dotted lines a pipe or tube in position to be grasped by the jaws. Fig. 3 is a view similar to Fig.2, showing the jaws closed upon the pipe or tube. Fig. 4 is a central vertical section on the line 4 4 of Fig. 5, a portion only of the handle being shown in elevation. Fig. 5 is a section on line 5 5 of Fig. 4. Fig. 6 shows in side elevation a slightly-modified form of the wrench, part of the handle being omitted. Fig. 7 shows in side elevation and partial section a slightlymodified form of wrench. Fig. 8 is a rear end view of the sliding jaw with the screw and its connected parts removed. Fig. 9 is a side elevation of the parts shown in Fig. 8, with a portion of the movable jaw broken away. Figs. 10, 11, and 12 are side and end elevations and bottom plan view, respectively, of the nut. Fig. 13 represents in side elevation and bottom plan View a modified form of nut. Fig. 14 is a sectional view similar to Fig. 5, showing a slight modification in the location of the pivot upon which the nut swings.
Similar letters of reference indicate similar parts throughout the several views.
In the drawings, A represents the handle of the wrench, which may be of a size and shape adapted to the particular use for which it is intended. At its end the handle carries a stat-ionaryjaw A, preferably formed with a serrated or notched face a, at a suitable predetermined angle to the handle A, as shown. Rising from each side of the handle and preferably above the jaw A are the two cheek- Serial No. 14,242. (No model.)
pieces a a, between which'the movable jaw B is adapted to have a sliding movement, as will hereinafter appear. The movable jaw 13, which projects beyond the stationaryjaw, is preferably provided at its front end with a serrated face I), which in the operation of the wrench is adapted to coact with the serrated face a of the fixed jaw, and extending rearwardly from said front end the said jaw B has a body portion B, which is adapted to fit and slide between the cheek-pieces a, a and is provided with a longitudinal slot 1). Carried by said body portion of the sliding jaw, and preferably seated in a groove formed therein below the slot 1), is a screw B the forward end I) of which is seated in a socket in the jaw and the plain or u nthreaded rear end 19 of which passes through a bearing b in the rear of the body portion and beyond said bearing is provided with a fixed collar 1). (See Fig. i.) The extreme rear end of the body portion of the sliding jaw is preferably extended, as at b", Fig. 4, and is provided with an external screw-thread upon which a correspondingly internally threaded ferrule 12 is fitted in a manner to prevent relative endwise movement between the screw B and the sliding jaw and to receive end thrust of the screw.
In order to provide a ready means for manipulating the screw 13 by turning it in the sliding jaw as desired, the screw is extended through and beyond the ferrule 5 as at b ,and has fixed thereto, preferably by a pin or setscrew 12 a knurled head b Thus the ferrule b and collar 12 prevent the screw from moving endwise in the sliding jaw, although permitting it to be readily turned or rotated therein. V
Seated in the longitudinal slot of the sliding jaw is a not 0, provided, preferably on its under surface, with a screw-threaded groove 0, adapted to engage the threads of the screw B This nut fits between the cheek-pieces a a, in which it is loosely connected by apivotpin c',which passes through a hole 0 in the nut above the screw-threads c. The nut O is provided with projections c ,which extend beyond the sides of the body portion of the movable jaw and embrace the cheek-pieces a a.
In assembling the parts the nut O is placed in the slot of the movable jaw, the screw is tions and changes-as, for instance, instead 1 of placing the screw B in a recess in the body portion of the movablejaw such recess might obviously be dispensed with, or, as illustrated in Fig. 6, the screw might be placed above the inserted, the ferrule or thimble is screwed placed between the cheek-pieces of the sta-: tionaryjaw or head, and the pivot-pin or rivet c is passed through the cheek-pieces and nut and headed, so as to hold the parts from dis- I placement.
From the construction described and shown it will be evident that by manipulating the screw B by means of the knurled head b the movable jaw B may be moved back and forth with relation to the fixed jaw A to thereby adjustsaid jaws to grasp a pipe, rod, or tube, as at P, Fig. 3,whereupon by turning the handle A in the direction of the arrow 8, Fig. 3, the movable jaw will rotate upon the pin 0, thus clamping the pipe, tube, or rod with a firm grip between the faces a and b of the jaws. A reverse movement of the handle A in the direction of the arrow 8 will reverse the rotation of the movable jaw, thus separating the jaws and promptly releasing the grip. As the handle is turned to grip the pipe, tube, or rod between the jaws strain will be placed upon the movable jaw, which through the screw 13 will be transmitted to the nut O, and
from it the strain will be transmitted to the cheek-pieces a a through the projections 0 0 which relieve the pivot-pin c.
In order to provide for the proper range of swinging movement of the movable jaw on the pivot-pin c, and thereby secure greater efficiency in the gripping action of the jaws, the front end of the handle adjacent the stationary jaw A is cut away or beveled, as at d, although this may not always be necessary and will depend upon the height of the pin connection between the cheek-pieces and the degree of swinging movement desired for the sliding jaw.
While I have described the above as the preferred embodiment of my invention, yet the construction is susceptible of modificaslot 5 and nut O. In this latter construction be provided in such case with a groove on its upper face, and the pin 0' will loosely connect the nut to the cheek-pieces below rather than above thecentral axial line of the nut, as in the preferred construction. In all other respects, however, the parts of the wrench illustrated in Fig. 6 are the same as those previously referred'to and need no further description herein.
Since the strain to which the movable jaw is subjected is always lengthwise of the wrench, with a tendency to force the sliding jaw longitudinally away from the stationary jaw, it is not necessary that the nut Cshould have lugs or projections c c at both ends thereof. In fact, as illustrated in Fig. 13, the
lugs at one end of the nut C may be omitted its preferred form, as illustrated in Fig. 4, yet
it is evident'that the details thereof may be variedinmanyrespects. Forinstance,instead of extending the rear end of the sliding jaw to form the screw-threaded bearing 71 for the ferrule 17 the said extension may be omitted and the rear end of the sliding jaw be internally screw-threaded, as at I)", to receive the eXteriorly-threaded ferrule 19 as in Fig. 7.
By pivoting the sliding jaw to the cheekpieces loosely and providing the nut with projections to engage the cheek-pieces the pivotpin 0 may be made light and yet durable, as all strain on the sliding jaw is transmitted through the heavier projections bearing against the cheek-pieces, and, if preferred,
the pivot-pin may be located in the center of the cheek-pieces, as shown in Fig. 14, instead of in the upper part of the nut, as shown in Fig. 4, or in the lower part of the nut under the'screw, as shown in Fig. 6; but in this case the pivot will consist of short studs projecting into recesses in the nut instead of passing clear through the nut, as in the other constructions.
What I claim is 1. A wrench, comprising an operating-handle provided with a fixed jaw, cheek-pieces projecting from said handle, a slotted movable jaw adapted to slide between the cheekpieces, a nut adapted to rock upon a center between the cheek-pieces and having projecting portions adapted to engage the outer edges of the cheekpieces to sustain the thrust upon the movable jaw, anda screw carried by the movable jaw and engaging said nut; substantially as described.
2. A wrench, comprising an operating-handle provided with a fixed jaw, cheek-pieces projecting from said handle on each side of said jaw, a movable jaw provided with a slotted body portion, a nut in said slotted body portion and provided'with a threaded groove,said nut being loosely pivoted between the cheek-pieces and having projections-to engage the edges of the latter, the said slotted body portion of the movable jaw being provided with a longitudinal groove, and a screw the jaw, a movable jaw provided with a slot, a nut in said slot, a screw carried by the movable jaw and provided with a collar, and a ferrule bearing against said collar to retain the screw in proper position in the movable jaw and receive the thrust of the screw, substantially as described.
In testimony whereof I aflix my signature in presence of two Witnesses.
