WRENCH.

Specification of Letters Patent.

PatentedMar. 23, 1915.

Application filed January 27, 1914. Serial No. 814,612.

To all whom it may concern:

Be it known that I, GILBERT M. HAGEY, a citizen of the United States, and a resident of the city of Monroe, Snohomish county, State of Washington, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to wrenches and has for its principal object to provide an article of this character in which the various adjustments of the wrench to accommodate nuts of different sizes is accomplished more quickly than has heretofore been usual in the art.

The invention will be fully described and explained in the following specifications, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a side elevation of my device partly broken away, with the side plate or cover removed. Fig. 2 is an edgewise view of Fig. 1.

Referring now more particularly to the drawings, 1 designates a plate whose opposite edges 2 are turned up at an angle to the main body of the plate to form a kind of housing for the parts. Pivoted at 3 is a lever 4 which forms the handle of the wrench, and beneath it, as seen in Fig. 1,

is a member 5 which is connected to the said lever by means of a spring 6: the said lever has a tooth 7 which is adapted to co-act with a notch 8 in a bar 9 which is slidable between the two limit stops 10 and 11 which are rigid with the plate 1. The said bar has teeth 12 which, when the wrench is in its position as seen in Fig. 1, are out of mesh with the corresponding notches 13 of the bar 14 which slides between one of the said upturned edges and the said limit stops. The bar 9 is normally held away from the bar 14 by means of leaf springs 13, one end of which is secured to one of the studs 13 which are rigid with the plate 1, and which pass through the said limit stops: and the other end of each of the said springs presses against one of the studs 13, which are also rigid with the plate 9.

In operation, the nut is placed between the jaw 16 and the member 5, the part 14 moved along until the nut is lightly gripped between the said jaw and member. The upper end of the lever 4 is then moved about its pivot 3 to the right, as seen in Fig. '1, which, due to the tooth 7, and notch 8, causes the plate 9 to move to the left, as viewed in Fig. 1, so as to bring the notches 13 into engagement with the teeth 12. This movement of the lever 4, due to the shoul- V ders 18 and 19 upon the said lever 4 and the member 5, respectively, has caused the said member to move very slightly, but sufii ciently to bring it into firm gripping contact with the nut and when the parts are in the position indicated the nut, of course, can be turned because the bar 14 cannot now have any retrograde movement with respect to the member 2, and the continued. movement of the lever 4, of course, forces the member 5 toward the aw 16.

I have shown a particular form of embodiment of my invention but am aware that many minor changes therein will readily suggest themselves to others without depart-l ing from the spirit and scope of the invention and I therefore desire to avoid being limited to the exact form hereinabove dein the first mentioned bar, a jaw rigid with T the said second bar, a second jaw adapted to cooperate with the first mentioned jaw and which is slidable within the said housing,

a tooth'upon the said lever which is oppositely disposed to its first mentioned tooth and a shoulder upon the said second jaw which is adapted to be acted upon by th last mentioned tooth of said lever.
