Specification of Letters Patent.

Patented Mar. 21, 15916.

Application filed June 17, 1913. Serial No. 774,244.

To all whom it may concern:

Be it known that 1, MICHAEL I. GINsBURG, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in renches, of which the following is a specification.

My invention relates to new and useful improvements in wrenches, and has for its object to so construct a wrench that it will have all the advantages of an adjustable wrench, while embodying the general features of a ratchet wrench and also the general features of a quick moving jaw wrench.

l/Vith these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use thesame, I will describe its construction in detail, referring by numeral to the accompanying drawing forming a part of this specification, in which- Figure 1 is a central longitudinal section of a wrench made in accordance with my improvement, the movable jaw and operating mechanism being left in elevation to clearly illustrate the same; and Fig. 2, is an edge view of a wrench.

In carrying out my invention as here embodied, 1 represents the housing or head of the wrench with which is formed the stationary jaw 2, and in this head is fitted the shank 3 adapted to slide crosswise thereof, said shank having formed therewith the movable jaw 4:. The shank 3 has formed upon its inner edge the teeth or sectional screw threads 5 with which meshes the adjusting screw 6.

7 is a spindle formed with or rigidly secured to the adjusting screw 6, and one end of this spindle projects into the hole 8, while the other end is adapted to pass into the hole 9. Around the lower portion of the spindle T is coiled a spring 10 which bears on the wall 11 of the head, thus normally holding the adjusting screw in its 1 socket and thereby normally retaining the movable jaw in its adjustment.

12 represents a dog which is pivoted at 13 within the head, the nose of which proects within the path of the lower end of the spindle 7.

14: represents the handle of the wrench, which is in the form of a lever pivoted at 15 within the head 1. This handle may be of any desired length to give the proper amount of leverage for operating the tool, varying of course with the size of the wrench and the work intended to be done therewith.

From the foregoing description the operation of my improvement will be obviously as follows: The movable jaw is adjusted to the size of the nut or other work to be oper ated upon by the proper manipulation of the adjusting screw 6, the spring 10 holding the jaws in a firm but yielding contact with the nut, when by pulling upon the lever in the direction of the arrow marked thereon the toe 16 of said lever will force the nose of the dog against the end of the spindle 7, thus holding the adjusting screw and consequently the movable jaw against any lengthwise movement. Thereafter any further pulling upon the lever 14L will operate the wrench in the usual manner. By reversing the power on the lever 14: the heel 17 thereof will swing the nose of the dog out of the path of the spindle 7, thereby releasing the latter and the adjusting screw 6,'leaving only the pressure of the spring 10 to hold the movable jaw in contact with the work. This will permit the movable jaw to be forced away from the stationary jaw when the wrench is forced in the opposite direction from the arrow, giving it all the effects of a ratchet wrench, namely permitting a new hold to be taken upon the work without removing the wrench therefrom. The effects of a quick sliding jaw wrench are obtained by forcing the jaws around the nut or other work against the action'of the spring 10 when the dog is out of contact with the spindle, and thereafter manipulating the adjusting screw, so that it will find its seat when upon the manipulation of the lever 14 in the direction of the arrow.

As above described the wrench will perform all the functions of the ordinary monkey wrench or open end wrench.

Of course I do not wish to be limited to the exact details of construction as herein shown, as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention what I claim as new and useful, is

1. In a wrench of the character described a head, a stationary jaw formed therewith, a shank fitted to slide crosswise of the head, a movable jaw formed with the shank, sectional screw threads formed upon one edge of the shank, an adjusting screw fitted within the head and meshing with said threads, a spindle carried by the adjusting screw, a spring mounted upon said spindle so as to hold the screw in its normal position when no work is done, but permit it to have a lengthwise movement when the wrench is reversed, a dog pivoted within the head and adapted to hold the adjusting screw against lengthwise movement, and a lever one end of which is pivoted within the head, said lever terminating in a heel and toe, adapted to operate the dog for holding and releasing the adjusting screw.

2. A wrench including an adjustable jaw, an adjusting means, a spring for normally forcing the jaw toward the work through the medium of the adjusting means, said adjusting means being slidable coincident with the jaw, a pivoted dog arranged to coact with the adjusting means for holding the adjustable jaw against the work, and a piv' oted operating handle for actuating the piv oted dog.

3. A wrench including an adjustable jaw, an adjusting means, a spring for normally forcing the jaw toward the work through the medium of the adjusting means, said adjusting means being slidable coincident with the jaw, a pivoted dog arranged to coact with the adjusting means for holding the adjustable jaw against the work, and a pivoted operating handle provided with means arranged to coact with the pivoted dog at two different points, one on each side of the pivot point of the dog, whereby said dog may be moved into or out of engagement with'the adjusting means.

4:. A wrench including an adjustable jaw, an adjusting means, a spindle carried by said adjusting means, a spring coiled about said spindle for normally forcing the jaw toward the work through the medium of the adjusting means, said adjusting means and spindle being slidable coincident with the jaw, a pivoted dog arranged to engage one end of the spindle for holding the adjust able jaw against the work, and a pivoted operating handle provided with means to coact with the pivoted dog for holding said dog against the end of said spindle.

5.
