Description

PATENTED APR. 24, 1906, P. A. HANES & W. STAPLES. RATGHBT WRENCH.

APPLICATION TILED JAN 20, 1906 UNITED STATES PATENT OFFICE.

FREDERICK A. HANES AND WILLIAM STAPLES, OF DISTRICT OF MUSKOKA,

CANADA.

RATCHET-WRENCH.

Specification of Letters Patent.

I atenteci April 24, 1906.

To all whom it Hui/y concern:

Be it known that we, FREDERICK A. IIANES, agent, and WILLIAM STAPLES, carpenter, of the District of Muskoka, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Ratchet-Wrenches, of which the following is a specification.

Our invention relates to improvements in ratchet-wrenches; and the object of the invention is to devise a simple, cheap, strong, and durable wrench of this class which may be used for various purposes, either as a plain or ratchet wrench, depending on the class of work it is desired to use it upon and which may be readily and securely held during use; and it consists, essentially, of a hollow socket provided with a suitable turning knob secured to the top of the same, a leverarm through which the socket extends, a gear-pinion secured to or forming partof the socket and located in a recess in the arm, and spring-pressed coacting dogs and latches for same designed to coact with the gear-wheel, the parts being otherwise constructed and arranged in detail, as hereinafter more particularly explained.

Figure 1 is a perspective View of our improved ratchet-wrench. Fig 2 is a view of the ratchet-wrench turned up and broken away, so as to exhibit the construction thereof. Fig. 3 is an enlarged vertical section through the socket and knob and lever-arm.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is a lever-arm provided with a jaw-like end A. The arm A is provided at the opposite end with a recess A and orifice A.

B is a socket designed to contain a wrench or any other tool. The socket B is provided with a gear-pinion B, attached to or forming part of the same and fitting within the recess A" in the arm A. A suitable set-screw B is provided to hold the tool or wrench in place.

The arm A is provided with side recesses A", in which are pivoted the lever-pawls C C, either of such lever-pawls being designed to be brought into engagement by the springs C with the gear-pinion E and either one or both being designed to be held disengaged by the pivotal clip C which is swung over the end of the lever-pawl remote from the pinion when the disengagement of the leverpawl with the pinion is desired.

which extends into an exterior groove in the socket. One portion of the divided plate E is provided with a lug G, through which extends an adjusting-screw H, such adjustingscrew being threaded .where .it extends through the lug.

The adjusting-screw II has an inner head H, which fits into a recess I in the socket B. The head H is withdrawable into a recess G when it is desired to disconnect the knob from the socket. The set-screw would be so withdrawn when it is desired to use the arm A and the wrench as a ratchet-wrench; but if it is desired to use the arm A as simply a means for holding the wrench in position and use the knob D for turning the socket, as may be required where the work done is not heavy, the screw II would be turned so as to insert the head H into the recess I in the socket, as indicated in Fig. 3. In this case, of course, the lever C would be disengaged from the gear-pinion B.

It will thus ,be seen that we are not only enabled to use our wrench as a ratchet wrench, but it may be used also as a plain wrench, using the knob D as a means of turning, and such socket in such case would be free to rotate in the orifice in the end of the arm A.

What we claim as our invention is In a wrench, the combination with the arm having an orifice formed in the end thereof, of a socket extending through such orifice and a pinion secured .in the orifice, spring-pressed pawl-levers engaging therewith, pivoted catches located near the ends of the lever remote from the pinion, a knob provided with a divided plate extending into an annular groove in the socket and having a lug formed on one of the portions thereof, and adjusting-screws extending through the lug and having an enlarged head designed to be brought into a recess in the socket or in the lug, as and for the purpose specified.
