In order to adapt the wrench tov sin 49 mg g gg P -"t gle hand use in the nature of a' pair of pliers, that is, in order toadaptit to'continual opening and g? 2 w-.9 the it 7 closing without locking, the inner side of the aux:

The numeral 2 s P I! p itions; 'Iherear nd, fthisl atch is 50 generally indicates the auxiliary-handle whi h i ,turnedto form the ear which directed to-' 50 connected with the main handle portiona's hereward th main ndle i inaiter described. '1he main handle portion I is 1 Cooperating'with the'latch II is a lug'll conformed at, its rear end tofprovide the interiorly nected with the outeredge ofthe fulcrum bar threaded sleeve 3 while at its forward end it is H and directed toward the inner side of the formed to provide the fixed low 4 and rearwardly 1 auxiliary handle to contact this handle whenthe two handles are in locked relation, just forwardly of the forward end oi the sliding latch it.

When the latch I6 is pressed forwardly to the limit of its movement as permitted by the pin l5, it will be interposed between the lug l9 and the handle 2 and the thickness of the latch is such that when it is in this interposed position, it will prevent the auxiliary handle 2 moving to the maximum extent to which it is capable, toward the main handle 3 and it will stop this movement of the auxiliary handle before it reaches the point where the pivot ID has passed beyond over the line between the pivot 9 and the bearing point of the fulcrum against the inner end of the screw i2. Thus the spring M will be constantly effective to pull the movable jaw l away from the fixed jaw 4 when the been swung in toward the main handle as far as the latch will permit it to go. It will thus be seen that when the latch is in operative position the wrench can be closed by drawing the auxiliary handle toward the main handle and it will instantly open under the urge of the spring is as soon as the auxiliary handle is released so that the wrench can be used like a pair of pliers instead of locking itself in closed position as ,it would do if the latch l8 were retracted.

shift the latch forwardly or rearwardly with the thumb so as to readily convert the wrench from one use to another.

What is claimed is:

1. In a wrench having a handle having a fixed jaw integral therewith, a movable jaw pivotally attached to the handle to move toward the fixed jaw and having an ear spaced from the handle, an articulated lever having two pivotally coupled sections, one section being pivotally' coupled with said ear, means carried by the handle forming an adjustable fulcrum with which the other section is movably connected, resilient means urging auxiliary handle has It will also be readily apparent that due to the person using the wrench can engage the ear and movement of the member on member having two working positions in prevent the breaking the movable jaw away from the fixed jaw, one section being extended to'iorm a second handle, a finger carried by the other section and directed toward the handle forming portion of the said other section and engageable with the second handle only when the lever is broken toward the first handle, a longitudinally slotted elongated slide member carried by the second handle, and a pin secured to the second handle and engaging in the slot of the slide to limit longitudinal movement of the slide, the slide when moved to one position being interposed between the second handle and said finger and preventing the breaking of the levertoward the other handle.

2. In a wrench having a handle having a fixed jaw integral therewith, a movable jaw pivotally attached to the handle to move toward the fixed jaw and having an ear spaced from the handle, an articulated lever having two pivotally coupled sections, one section being pivotally coupled with said ear, means carried by the handle forming an adjustable fulcrum with which the other section is movably connected, resilient means urging the movable jaw away from the fixed jaw, one section being extended to form a second handle, said second handle when moved toward the first handle to a predetermined position breaking said lever toward the first handle, and means between the second handle and the said other section of the lever for preventing the said breaking of the lever, including a longitudinally slotted elongated slide member positioned upon and extending longitudinally, of the second handle, and a pin engaged in the slot of said member and secured to the second handle and limiting longitudinal the handle, the

slotted one-of which positions it limits the movement of the second handle towards the first handle to of said lever, the breaking of the lever being possible only when the member .isin the other one of its two positions. 1
