John A. Bommhardt - patent attorney
This invention relates to an operating lever or handle adapted particularly for use in connection with the winding shafts of dump cars or the like, although capable of use on jacks and other power devices. These articles are usually known as "wrenches," and the object of the invention is to provide a safety device of the kind, by the use of which it is impossible for the operator to get hurt. The invention is particularly directed to the means for holding the pawl of the lever engaged with the ratchet, and for releasing the same therefrom to permit the free turn of the ratchet wheel shaft, said means in the present embodiment comprising a locking lever by the operation of which the pawl is advanced or retracted.
