Specication of Letters Patent.`
Patented Apr., 29, 19H9..
To all whom-t may concern:
Be it knbWn that we, MELoHioR MILLER andi/Mirano D. BURG, citizens of the United States,--pt'esidents of Le Mars, county of vPlymouth, State of lowa, have invented certain new and useful improvements in Wrenches, ot which the followingis a specification. v i
Mbireeobject of our invention is to improve the wrench shown and described in a pend- ,ing application for Letters Patent of the United States, 'led by us on the 2nd day of December, 1915, Serial No. 64,725, to the end that any desired number of wrench jaws adapted for nuts or bolts" heads of various shapes and'sizes can be used with a single shank, thereby eEecting a considerable sav ing in the cost and Weight of a wrench equipment or set.
Other objectsof the invention will appear from the following detailed description.
The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.
ifthe accompanying drawings yforming part of this specification,
Figure l is a viewl of a Wrench embodying our invention,
Fig. 2 is a sectional viewv through the shank of the wrench, showingl the manner of mounting a jaw thereon,
Fig. 3 is a detail sectional view of the joint between the two sections of the wrench,
Fig. 4 is an end view of one of the jaws removed from the Wrench shank,
Fig. 5 is a side view of one of the jawshanks and its head removed from the wrench shank.
In' the drawing, 2 and 3 represent the Shanks and hand grips of the Wrench. The
. abutting ends of these Shanks are pivotally connected to one another by a pivot pin 4 and one of the Shanks has ratchet teeth 5 v formed therein in position to be engaged the socket 8 and provided with an annular grom'e 1l. A latch l2 is mounted to enter said groove and is normally held therein by means of a spring 13l fitting within a recess 14 in the shank of the hand grip. The shank 9 preferably has a shoulder l5 formed thereon which contacts with the end 7 for limiting the insertion of the shank 9 into the socket 8 and insuring the proper register of the groove 1l with the locking latch.
At the outer end of the shank 9 we mount a jaw head, preferably in the orm shown, consisting of a` disk-'like member 16 arranged lin a plane at right angles substantially to the longitudinal axis of the shank v9 and mounted eccentrically with respect thereto. A recess 17 is provided in the head, extending inwardly, preferably to a point near the shank, This recess has opposing faces 18 in planes parallel with the serted into the recess. rThis jaw head may be made in various sizesand its shape may be modified, if preferred, and it is preterably rigidly mounted or secured on the jaw shank, the recess 17 therein being adapted for dierent sizes and shapes of nuts or bolt heads.
The sockets 8 are of different sizes, and the Shanks 9 fitting therein also vary in cross sectional area and have heads of different sizes thereon, so that with a single shank or handle the tool vmay be adapted for use as a large or a small wrench. Generally it is necessary to provide wrench Shanks of different length and jaws of different strength and weight to adapt the Wrench for use on large or small nuts or bolts, while our invention contemplates the combination of a large and a small wrench in one and a variety of jaws for both the large and the small wrench, to adapt the tool for all requirements of a tool of this kind.
We have designated the two sizes of shanks by the same reference numeral, as they are preferably formed in substantially the same way, the difference consisting generally in using a smaller gage of jaw shank and jaw head therefor at one end of the wrench than at the other.
By providing an annular groove 11 in the end 10 we are able to insert the sha-nk 9 therein with the head projecting in either j longitudinal axis ot the shank and adapted to bear on the nut or bolt-head that is ini in direction, according to the convenience ,of the user of the tool, and as these Shanks all correspond substantially in size, we may provide a series of the shanks 9 and the heads thereon with -dierent sizes of sockets 17, so that the user of the wrench can have a suiiicient'number of jaws of diierent sizes to t all the dierent sizes of nuts and bolts on which he may wish to use the tool.
It often happens that the user of this tool wishes to rotate it when the shank members are in line with each other and when one shank and the head thereon can he used as a hand grip for operating the other shank, as, for instance, when it 1s found necessary to operate the tool through the spokes of a Wheel or in some position on the car where there is no room to move the tool with one p :17, recare? We claim as our invention:
A wrench comprising hand grip Shanks having abutting ends hinged together, the opposite ends of said Shanks having longitudinal sockets formed therein, jaw sha fitting within said sockets and having means for holding them against rotary movement and having heads formed thereon and provided with jaws and gripping faces in planes parallel substantially with the axes of vsaid jaw. Shanks and eccentric with respect thereto, the jaws of said Shanks being of varying size to adapt the wrench for nut and bolt heads of different sizes, each hand grip shank being mounted for angular adjustment with respect to the other shank, or for alinement with each other, and either jaw shank and head thereon :forming a hand grip for rotating the tool and the other jaw shank. when said hand grip Shanks are in line with each other.
in witness whereof, we have hereunto set our hands this 9th day of March 1916.
