Specification ofLetters Patent.

Patented March 10, 1908.

Application filed May 25, 1907. Serial No. 375,755.

To all whom it may concern:

Be it known that I, HENRY D. SARGENT, a resident of Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following specification is a full, clear, and exact description of the same.

This invention relates to new and useful improvements in Wrenches and has relation more particularly to that class termed ratchet wrenches.

It is an object of the invention to provide a novel device of this character whereby the rotary movement is imparted to the engaging element by an oscillation or reciprocation of a handle. v

It is a further object of the invention to provide a novel arrangement in a device of this character whereby the binding of a member between the engaging member and the handle will assure proper rotation of the engaging member.

It is a further object of this invention to provide a novel device of the character noted, which will possess advantages in points of sim licity, efliciency and durability, proving at t e same time comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accom anying drawings forming part of this spec' cation wherein like characters denote corresponding parts in the several views, in which Figure 1, is a view in top plan partly in section illustrating the invention. Fig. 2, is a longitudinal sectional view of the invention. Fig. 3, is a view in perspective of the engaging member with a part omitted,-said member being shown detached. Figs. 4 and 5, illustrate certain details of the invention.

In the drawings, 1 denotes the.handle or operating member of the device which is enlarged at one end as at 2, said enlarged end being provided with the circular opening 3. Rotatably mounted within the opening 3, is the engaging member 4, which is rovided with the angular bore 5. Formed a ongone edge of the engaging member 4, is a flange 6,

which is intended to contact with a face of the handle 1, while the opposite edge of the engaging member has secured thereto in any desired manner the ring 7, which is intended to engage the opposite face of the handle. By this means theengaging member 4, is retained within the opening 3, as will, it is thought, be fully understood. The intervening space on the periphery of the engaging mem er 4, between the flange 6, and the ring 7, is milled or provided with a series of concaved recesses, as at 8, more particularly shown in Fig. 3. It is also to be stated that this milled periphery of the engaging member is circular.

Formed within the wall of the opening 3, adjacent the extended portion of the handle 1, is an approximately segmental recess 9, which communicates with the opening 3, tangentially of the wall of said opening. That portion 10, of the recess 9, at its junction with the opening 3, is enlarged to form a chamber in which is located a cylindrical steel body 11, which engages the milled periphery of the engaging member 4, and binds between the milled periphery-of the member and the wall of the chamber 10, and causes the engaging member 4, to rotate with the handle when the handle is moved in one direction, or in a direction toward the opened end of the recess 9.

While it has been fully demonstrated that the weight of the body 11, is suflicient to assure the proper contact for the operation of the implement, better results are attained by placing within the recess 9, the spiral spring 12, which exerts sufiicient pressure to hold the body 11, inits operative position.

The operation of this tool is thought to be obvious but it is believed well to statethat the body 11, rotates and as the wrench is used, or the handle turned, the rotation of the body 11, allows the body to readily fall into the concaved recesses 8, and that the spring 12, holds the said body 11, in its operative position. It is also to be observed that the se mental recess 9, forms at its junction with t e opening 3, a shoulder against which the body 11, abuts, as is clearly shown in Fig. 1.

What I claim is: I In combination, a handle having an opening and a tangential recess in the wall of said opening, a shoulder formed at the junction of the recess a-nd opening, a .detent 'on the shoulder, a spring in the recess back of the .detent, a nut-engaging member having engaging member against movement in one direction independently of the handle.
