WRENCH.
Application filed. April 17, 1922.
"T0 all whom it may concern:
Be it known that I, ARTHUR J. WHIT- menu, a citizen of the United States, residin g at Boston, in the county of Suffolk and State of Massachusetts have invented an a 7 .E
improvement in renches, O]. which the followin description, in connection with the claimed, and the present invention contemplates a further development of such tool to adapt it not only as a pipe wrench but also as a nut or monkey-wrench.
In accordance with the present invention, the general construction of the tool whereby the sensitive gripping action is; rendered possible, is the same as that of the prior application, and the improvement in the pre-sent instance relates more particularly to the construction of the two jaws whereby they may be adapted tonon-inj uriously grip a nut and either set it up or loosen it by repeated Iotative movements of the tool. .More specifically stated, the two jaws are, in addition to the teeth which may be advantageously employed for grasping a pipe toothed and turning it, provided with plain or unangular portions between the toothed portion and the housing of the tool for grasping the exterior surfaces of a put,
all of which will more fully appear.
In the drawings Figure l is a side elevation of a hand tool embodying the present invention;
Fig. 2 is a view similar in character, with some of the parts broken awa showing the tool employed in connection with a nut of smaller size; and
Fig. 3 is an end view showing the tool used as a socket wrench.
The tool comprises the housing 1 which may be conveniently formed integral with the handle 2, substantially as shown and described in the prior application. Pivotally mounted at 3 is the other handle 4, which is provided with a cam 5 for actuating the jaws.
One of the jaws is cam-actuated, and
Serial No. 553,883.
as shown in the present instance of the invention, the upper jaw 6 is the camactuated jaw and is pivoted at 7 to the 'housing 1. The jaw 6 has an extension. 8 provided with a socket 9 threaded for the reception of the adjustable stem 10, the head 11 of which is preferably knurled and rests upon the cam 5. The other jaw 12 is pivoted independently to the housing at 13 and is provided with an upwardly-extending toe l4.which overlaps a downwardly-extending toe 15 of the upper A spring 16 is wound about a stud 17 extended transversely between the side members of the housing 1, and bears upon the upwardly-extending toe 14 of the lower jaw. The other end 18 of the spring rests upon a shouldered portion 19 of the handle 4, the' construction being such that when the handle 4 is pressed toward the handle 2, the cam-actuated jaw Willi be turned upon its pivotal support 7 and the toe portion 15 thereof,
acting upon the toe portion 14 of the lower jaw will: cause the lower jaw to simultaneously move with the upper jaw to grip the work. 7
The upper and lower jaws are provided with series of teeth 20 which are constructed and arranged to act as a pipe wrench, substantially the same as in the prior application.
The front edge portion 21 of the hou'sing extends between the. two jaws and beyond the front wall 21 of the housing, and between it and the teeth 20 of the two jaws the jaws are each provided with untoothed angularly-arranged nut-gripping portions for, acting upon a nut such as a placed between them.
' The nut-gripping portions of each jaw comprise a plain untoothed surface 22 which extend in diverging relation from the toe portions of the jaws toward the toothed portions thereof. The end tooth 23 is preferably enlarged on each jaw, and has its end wall carried inwardly to join the straight untoothed portion 22 at 24, the construction being such that a nut, such as a (Fig. 1) placed between the two jaws, will have its hexagonal surfaces engaged by .the wall of the end teeth of the jaws and by the untoothed surface 22 of each of the jaws in front of the housing. The wall 25 of the toe 15 is preferably made straight, as indicated in Figs. 1 and 2, so that when a ion large nut as in Fig. 1, is placed between the adjusting stem 10 for the reception of said nut, one of the hexagonal walls of the nut a will rest against thesurface 25 of the toe 15.
When .it is desired to use the tool for turning a nut of smaller dimensions, as for instance shownby Fig. 2, the adjusting stem 10 is manipulated so that the plane of untoothed surface portions of the jaws willgrasp the nut b, Fig. 2, at the corner portions 0 and hold it with sufficient firmness and grip to enable the nut to be turned up or loosened. i p
Regardless of the size of the nut so long as its size is within the capacity or" the tool, the nut may be grasped by the inturned surface'of the jaws, and when the handles,
2 and 4 are closed toward each other, the cam action will cause the two jaws to grip the nut with firmness and when the nut has been turned, loosening of the handles will permit the jaws to automatically open sufficiently under the action of the spring 16, for the tool to be turned into position to take another hold of the nut.
It may sometimes be desirable to use the tool as a socket nut wrench, and to this end each of the jaws is provided with a smooth end portion 26, well shown by Fig. 3. Thus, by
for ordinary side work the jaws will beadjusted by the adjusting stem 10 to grasp the desired size nut and then move back and forth by a release and grip action of the handles to cause the nut to turn. When a nut is inaccessible for side work the end portions 26 maybe utilized as a socket wrench for turnlng the nut as indicated in Fig. 3. Thus while the tool is adapted for turning pipes as describedin the previous application, the present improvement further adapts the too-l for use as a nut or monkey-wrench.
What is claimed is 1. In a hand tool having opposing jaws for engaging the work, a head having a handle extending therefrom, a pair or" 1 pivoted cooperating jaws each having a pivot pin disposed a substantial distance from the other pivot pin and extending through a jaw into the head for pivotally connecting the jaws to the head, each jaw provided with a toothed portion and a nut receiving notch disposed between the toothed portion and head to grasp and manipulate a nut having its corners seated in said notches and positioned to exert a turning torque in the direction of a pivot pin, a second handle or lever pivotally connected to the first handle, and means for impart-ing movement from the second handle to said jaws.
2. In a hand tool having opposing jaws for engaging the work, a head having a handle extending therefrom, a pair of pivoted cooperating jaws each pivoted to the head and having their respective pivots disposed a substantial distance apart, each jaw provided with a toothed portion and a nut receiving notch disposed between the toothed portion and head to grasp and ma nipulate a nut having its corners seated in said notches and positioned to exert a turning torque in the direction of a jaw pivot, a second handle pivotally connected to the first handle and having a cam, and an adjustable stem threaded to one of the jaws and bearing on the cam to be actuated there- 3. In a hand tool having opposing jaws for engaging the work, a head having a handle extending therefrom, two jaws independently pivoted to the head with their pivots disposed a substantial distance apart and having overlapping toe portions, each jaw provided with a toothed portion and a nut receiving notch disposed between the toothed. portion and head to grasp and manipulate a nut having its corners seated in said notches and a portion of the nut resting against one of said toeportions, a second handle pivotally connected to the first handle, and means for imparting movement from the second handle to one jaw and to the other jaw through said toes.
In testimony whereof, I have signed my name to this specification.
ARTHUR J. WHITFIELD.
