Application April 23, 1953, Serial No. 350,609
1 Claim. (Cl. 81-112) This invention comprises novel and useful improvements in a screw actuated pivoted jaw wrench with die stock attachment.
The primary object of this invention is to provide an improved construction of wrench wherein the jaws may be more conveniently adjusted and maintained in adjustment by a mechanism housed within the body of the wrench.
A further object of the invention is to provide in a wrench construction of the character set forth in the preceding object an attachment whereby a die stock may be conveniently manipulated by the wrench.
A further object of the invention is to provide an improved wrench wherein the component parts of the same may be of simple and inexpensive construction, and yet easily assembled or disassembled as required.
A still further object of the invention is to prov1de a wrench having an improved mechanism for effecting movement of the jaws of the same and for maintaining the jaws in an adjusted position.
These together with other objects and advantages which Will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a vertical sectional view, parts being broken away and parts shown in elevation, of a construction of wrench incorporating therein the principles of this invention and showing a die stock attachment applied to the jaws of the same; and
Figure 2 is a side elevational view of the embodiment of Figure 1, taken from the right side of the same, parts being broken away and shown in section.
The body portion of the wrench illustrated in the accompanying drawings consists of a casing having a removable cap 12 which in turn has a handle 14 secured thereto. The casing may conveniently be of cylindrical shape, being open at its upper end and provided with external threads 16 upon a reduced portion which is adapted to receive corresponding internal threads carried by the cap member 12. At its other end the casing 10 is preferably provided with an integral wall 18 which is centrally apertured as at 20.
The cap portion 12 at the opposite end from that which engages the threaded portion 16 of the casing is provided with an internally threaded extension in the form of a sleeve 22, the latter having internal threads 24 which extend down to a partition 26 having an axially disposed internally threaded bore 28 therethrough. This bore communicates with the interior of the casing 10 to which the cap is attached, and to the internally threaded bore 24 into which is screw threaded the externally threaded end portion 30 of the tubular handle member 14.
A rod 32 having a removable crank arm 34 carried upon its outer end, extends loosely through the axial bore or passage 36 of the tubular handle 14, and passing through the bore 28 extends into the interior of the casing 10. At its inner end, the operating rod 32 is provided with external screw threads 38 which engage the threaded bore 28 whereby the rod may be adjusted inwardly or outwardly of the casing by rotating the crank handle 34 thereof. This rod constitutes an operating means for the jaws of the wrench in a manner to be now set forth.
A pair of jaws 40 and 42 are provided, each of which 2,704,003 Patented Mar. 15, 1955 is semi-diamond shaped, having two sets of oppositely disposed teeth 46 and 48 upon their inner surfaces, the teeth of the two jaws defining a substantially diamondshaped opening therebetween. Each of the jaws has an angularly disposed shank portion 50 and 52 for the jaws respectively, and which extend through the aperture 20 into the interior of the casing 10. The shank upon their inwardly extending portions are provided with arcuate recesses 54 and 56 respectively through which extend fastening and pivot pins 58 and 60 respectively which are supported in any suitable manner by the opposite walls of the casing 10.
As so far described it will be apparent that as the shanks are moved longitudinally of the casing, the arcuate travel of the slots about the pins will cause the jaws to move towards and from each other.
At their inner ends, the shanks are pivotally secured as by pins 62 and 64 to a crosshead 66 carried by the rod 32. This crosshead, as will be better seen in Figure 2, consists of a pair of parallel straps or bars 68 and 70 having the pins 62 and 64 extending across their opposite ends. Intermediate their ends the bars 68 and 70 are rigidly secured to a member 72 which is loosely rotatably received upon the end of the rod 32, being retained thereon against axial movement by means of a collar 74 which may be integral with or separately and rigidly attached to the rod, and a retaining nut 76 secured to the end of the screw threaded rod. By this means rotation of the rod 32 is permitted, and the resulting longitudinal movement of the rod by virtue of its screw threaded engagement with the bore 28 will impart a longitudinal movement to the crosshead and the shanks of the jaws connected thereto.
Illustrated in the drawings is a die stock attachment which is removably and adjustably secured upon the jaws of the wrench whereby the wrench may be employed to manipulate the die. Thus, a pair of blocks 78 and 80 are removably secured to the apices of the jaws as by fastening bolts 82.
Extending through the blocks 78 and 80 are aligned bores 84 which rotatably receive the opposite rod- like handles 86 and 88 of a stock 90 provided with a die 92. A setscrew 94 is provided in each of the blocks to intersect the bore thereof and engage the handles 86 and 88 to lock the die stock in adjusted position with respect to the jaws. 7
It will thus be apparent that the die and die stock may be mounted upon the jaws in various positions of angular adjustment about the handles of the stock whereby the wrench may be positioned at different angular positions with respect to the die to thereby facilitate the use of the die. Alternatively, the die and stock attachment may be removed from the jaws whereupon the wrench may be employed in the conventional manner.
From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim.
What is claimed as new is as follows:
A wrench comprising a handle and a casing carried thereby, a pair of jaws having shanks extending within said casing, means for actuating said shanks, said means including a crank operated screw, said handle being tubular and the screw operating therethrough, a pair of parallel bars rotatably carried on the inner end of the screw and between which said shanks are pivoted and whereby said shanks are actuated, said shanks having arcuate slots, pins secured to said casing and extending through said slots for guiding the shanks, each of said jaws being semi-diamond shaped and each having two sets of teeth, each set of teeth being inclined toward the other set on its respective jaw.
