Application filed March 2,1907. Serial 110.360.2663.

To all whom it may concern:

Be it known that I, EDWARD I. ALLIsoN, a citizen of the United States, residing at Saginaw, in the county of Saginawand State of Michigan haVe invented cer tain new and useful Improvements in Buggy-Wrenches and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to wrenches, and more particularly to that class of wrenches known as buggy wrenches or bur wrenches, one object of which is the provision ofa wrench equipped with means for holding the bur or nut in the jaw after its removal from the axle of the vehicle.

A further object is the provision of a wrench equipped with an integral stop, lever and yielding finger all combined.

Another object is the provision of a wrench of this description consisting of the fewest number of parts so assembled that it is practically impossible for them to become out of order, lost or broken, with ordinary care.

By the use of my invention, the actual handling of the nut which is usually besmeared with grease is avoided, and the wrench is simple, inexpensive strong and durable.

To these and other'ends, therefore, my invention consists in certain novel features and combinations, such as will be more fully described hereinafter and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a bottom plan view of the invention; Fig. 2 is a side view of the invention; Fig. 3 is a detail sectional view of the jaw; and Fig. 4 is a detail view of the combined spring, lever, stop and finger.

(A) indicates a handle provided at one end with a hollow approximately square jaw (1) arranged preferably parallel with the handle, the metal being cut away, as at (2), to lighten the construction andfpermit a view of the nut in the jaw, the handle being curved over to meet the jaw.

The rear or free end of the handle is flattened out, as at (3), at right angles to the remainder of the handle, to enable it to more easily and readily fit the grasp of the operator, such flattened portion being provided at its end with a jaw (4), as shown. I The handle may be formed either solid or hollow.

The hollow approximately square jaw (1) is provided with an offset (5) of any convenient shape, it being shown as rectangular in the present instance, such offset being open at the upper end, as at (6), beneath the handle (A).

Located at the bent over portion of the handle is a wing (7) which not only strengthens the construction, but also affords a support for a laterally projecting post (8). A spring which may be composed of steel wire,

for instance, is provided, the spring being doubled to form a lever (9) extending beneath the handle (A). Near its ends, the spring is coiled, as shown at (10) (10), the coils being received loosely upon the post (8). The free end (11) of one arm of the spring constitutes a stop which is bent rearwardly and takes against the handle (A), whereby the lever portion is normally held at an angle to the handle (A); The remaining free end (12) of the spring is bent oppositely to the free.

end (1].) and is passed down through the opening (6) into the offset (5), the free end (12) constituting a yielding finger adapted to engage and hold the nut while in the jaw (1), the finger normally projecting out of the offset into the jaw. The offset need only be of sufficient size to receive this finger, but for convenience in manufacture, I prefer to make it of the shape shown.

In using the wrench, the operator grasps the handle and with his forefinger or thumb, presses the lever (9) toward the handle against the tension of the spring, thereby withdrawing the finger into its recess or offset and permitting the hollow jaw to embrace the nut, after which the lever is released and the wrench turned in the usual manner to remove the nut, the latter being held firmly in the jaw by the pressure of the finger (12) against the side of the nut. A reversal of this operation replaces the nut, and permits the wrench to be removed.

It is evident that I have devised a most simple construction. The wrench may be composed of any cast or malleable metal and the spring of any suitable material. The coils are prevented from disengagementfrom the post by means of a rivet or other headed fastening (13) secured to the free end of the post, the latter lying beneath and protected by the handle (A).

Having thus fully disclosed my invention, what I claim as new is 1. A wrench comprising a handle, one portion of which lies at approximately right angles to the remaining, portion, a hollow jaw on one end of the handle, the jaw provided with an offset terminating in an opening beneath the handle, a wing carried by the handle near one edge thereof, a post projecting laterally from the wing beneath and protected by the handle, a spring bent to form a lever, coils formed near the free ends of the spring, one'of the free ends being bent backwardly and taking against the under face of the handle to constitute a stop, the remaining free end of the spring passing down through the opening into the offset, the coils received on the post and means for retaining the coils on the post.

2.- A wrench comprising a handle, a hollow jaw at one end of the handle, a support carried bythe wrench and a spring lever journaled on the support, and normally lying at an angle to the handle, one end of the spring lever terminating in a clamping finger projecting into the hollow jaw, the opposite end of the lever engaging the wrench to form a fulcrum for the lever, the lever and handle adapted to be grasped to bring the lever approximately parallel with the handle when placing the wrench on a nut.

3. A Wrench comprising a handle, bent at one end, a hollow jaw carried by the bent end of the handle, a wing carried by the handle, a post projecting laterally from the vided with a recess or ofiset, the clamping finger movable wing, a combined integral spring, lever and clamping finger into and out 01; the recess in the hollow jaw, and a stop pivotally mounted on the post, and means for preventing carried by the lever and taking against the handle to its disengagement from the post, the clamping finger norafford resilience to the lever and clamping finger.
