CLARK W. THOMAS, OF FRAZEYSBURG, OHIO WRENCH. I
SPECIFICATION forming part of Letters Patent 110,752,811, dated February 23, 1904.
u Application filed July 8 ,1903.
To all whom it may concern:
zen of the United States, residing at Frazeysburg, in the county-of Muskingum and State of Ohio, have invented certainnew and useful Improvements in Wrenches, of which the following is a specification.
This invention hasrelation to wrenches of the type provided with a pivoted jaw and a rigid jaw, one being adjustable with reference to the other to admit of varying the space between the jaws to adapt the wrench for dif ferent-sized objects and work.
An essential feature of the present invention is an interlocking connection between the two jaws whereby they mutually brace each other laterally or at a right angle to the plane of movement of the pivoted jaw.
A further purpose of the invention is to de-.
vise a simple, compact, and effective construction, easy of operatlon, comprlsinga minimum amount of material in its organization,
durable, and readily accessible to all of its parts to admit of necessary repairs being quickly and economically made.
For a full description of the invention and the merits thereof and also to acquire a knowl-. edge of the details of construction of the means for effecting the results reference is to be had to the following description and drawings hereto attached. a
While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a wrench embodying the essential features of the invention. Fig. 2 is a side elevation showing the operation of the pivoted jaw by dotted lines and having the inner side of the slide-frame omitted. Fig. 3 is a transverse section on the S erialNo. 164,707. (No model.)
with corresponding teeth at the outer or lower edge of the handle-bar 9, so as to hold the latter at an adjusted position with reference to the slide-frame 1. outward upon the rear end of the latch-lever, thereby forcing the projection 7 inward, whereby its toothed portion is normally'held in engagement with the teeth 10.
The pivoted jaw 12 is approximately of elbow or right-angular formation, and its shank 13 is let into the compartment 3 and is pivoted to the slide-frame by the pin 14, passed through openings in the side walls of the frame and in the said shank. A spring 15, located within the compartment 3, normally exerts an outward pressure upon the shank 13 of the pivoted jaw, so as to hold it away from the handle-bar 9, as indicated most clearly in Figs. 1 and 2.
The handle-bar 9 is slidable in the compartment 1 and is provided at its inner end with a jaw 16, the inner endof which is notched, as shown at 17, to receive the shank 13 of the pivoted jaw, which, in effect, constitutes an interlocking connection, so as to enable the jaws to mutually brace each other when subjecting the wrench to lateral strain in a direction ata right angle to the plane of movement of the pivoted jaw.- By pressing upon the rear end of the latch-lever 6the handle-bar is released, thereby permitting the slide-frame to move thereon in the event of the handle-bar being held stationary or the handle-bar to be slid in the compartment 4: upon holding the slidelatch-lever and handle-bar are of such formation as to admit of relative movement of the The inner face of the pro-' jection 7 is toothed and is adapted to engage A spring 11 presses frame stationary. The teeth between the the slide-frame is recessed, as shown at 5,: to
jaws to diminish the space between them without necessitating operation of the latch-lever by hand; but when it is required to move the jaws apart it is incumbent upon the vuser to,
operate the latch-lever so as to release it from the handle-bar, when the parts 1 and 9 may be relatively moved to separate the jaws. The gripping-faces of the jaws have their teeth facing in opposite directions, and when the work is gripped between the jaws and the wrench turned forward by grasping the handle-bar the pivoted jaw moves so as to more effectually grip the work proportionate to the amount of force expended for operating the wrench. 7
Having thus described the invention, what is claimed asnew is a 1. In a wrench, the combination of a slidefrarne comprising independent longitudinal compartments, a jaw of approximately elbow form having its shank inserted in one of said compartments and pivoted therein, a spring normally exerting an outward pressure upon the pivoted jaw, a handle-bar slidable in the other compartment and provided ,at its inner end with a jaw for cooperating with the said pivoted jaw, and a latch-lever pivoted to the slide-frame and adapted to make positive. en-
' gagement with the said handle-bar to hold it in pivoted in one of said compartments, a spring located in the compartment with the pivoted shank and normally exerting an outward pres sure thereon, a handle-bar slidably mounted in the other compartment and provided at its inner end with a jaw notched at its inner end to receive the shank of the pivoted jaw when the same moves inward to cause the jaws to mutually brace each other, and a latch-lever 7 applied to the slide-frame for securing it and ment and provided at its inner end with a jaw having a notch to receive the shank of the pivoted jaw to enable the jaws to mutually brace eachother, and a spring-actuated latch-lever pivoted in the recess of the slide-frame and having a projectionat its inner end passed through an opening of the wall separating said recess from the adjacent longitudinal compartment so as to engage with the handle-bar and secure it and the slide-frame in a relative adjusted position, substantially as specified;
In testimony whereof I affix my signature in presence of two witnesses.
