SPECIFICATION forming part of Letters Patent No. 726,782, dated Apr i128, 1903.- Application filed June 20,1902. Serial lilo. 112,450. (No model.)

To all whom it may concern.-

Be it known that L-NATHANIEL B. STONE, a citizen of the United States, residing at Outlook, in the county of Yakima and State of -Washington,'have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

My said invention consists in certain improvements in the construction of wrenches, particularly wrenches of that class commonly termed carriage-wrenches, being especially adapted for the removal and replacing of the nuts of vehicles, whereby such a wrench is provided which is very convenient in use, as will be hereinafter more particularly described and claimed.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts, Figure 1 is a top or plan view of a wrench embodying my said invention; Fig. 2, a side elevation of the same; Fig. 3, a cross-section looking in the direction indicated by the arrow from the dotted line 3 3 in Fig. 1, and Fig. 4 a longitudinal section on the dotted line 4 4 in Fig. 1.

The wrench consists of a cast-metal bar or handle A, having a socket A on one end of a form adapted to receive the nut for which it is intended. Said socket is set ofi to one side of the line of the handle, as shown, whereby it is adaptedto extend within the hub-flange to engage the not, as is usual in this class of wrenches. A spring-clamp a, formed on the end of the spring-bar a extends within the socket A, on one side thereof, projecting through a slot in the wall of said socket. The bar a is of spring metal and bent in the form Its lower arm rests in a recess in the top of the handle A and its vertical arm in a recess in the adjacent. face of the Wall of the socket A. A cross-pin 1 or a suitable retaining device secures said bar in said recess at its angle. A cross-pin 2 is also preferably provided in the slot in the upper side of the socket, which serves to limit the movement of the vertical arm of the spring. By reason of this cross-pin the upper end of the clamp is prevented from projecting inwardly to interfere with the ready placing of the socket on the nut and from being bent outwardly sufficiently to be ineffective in use.

The clamp being carried on the long flexible spring extending parallel with the side of said socket moves bodily in a plane substantially parallel with the"side-of the nut and gives easily to permit the wrench to be placed on the n ut and at the same time presses upon said nut with force sufficient to prevent it from being accidentally dislodged from the socket. A circular finger-hole 3, with a smooth interior surface, is formed in the handle about midway its length, and other apertures 4:, 5, and 6 angular in form may be provided in said handle to fit various-sized nuts on the vehicle, and a universal toothed wrench 7 is preferably formed on the outer end of the handle, so that the tool will be adapted for the removal of any nut on the vehicle. Laterally-projecting wings a are formed on the back of handle A at its point of connection with the socket A, which serve to support the wrenchfrom tipping over when laid down, as is usually done after the operation of removing an axlenut while the axle is being oiled. This serves to prevent the said nut from being tipped into the dust or dirt, (a common annoyance in oiling vehicles,) and thus avoids the necessity of cleaning said nut before replacing it.

In use the socket A is placed over the nut in the usual manner, the clamping-spring a. being pressed backinto the recess by the operation, said springbeing bent at its angle under cross pinil and the clamp receding bodily into the recess in the wall of the socket. Saidclamping-spring will press against the side of the nut with suflicient force to retain it against accidental dislodgment from said socket while removed from the axle. After the nut has been started off the wrench can be rapidly and conveniently whirled around and around by inserting the finger through the aperture 3 in'the handle until the nut shall be entirely removed, when the wrench will fall and rest upon the finger and-can be laid aside with the nut held in-its socket by said springuntil it is desired'toreplace the nut, when after being started on it can be rapidly turned to its seat in. the same manner. By reason of the finger-hole 3 being'made circular and smooth this operation can be carried on without inconvenience or injury. By this means the nut can be rapidly and conveniently manipulated without the necessity of touching it with the hand and will be safely supported while removed without danger of tipping into the dirt, as before mentioned.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. A wrench comprising a handle, a slotted socket for the nut thereon, a spring-clamp seated in the angle of the handle and socket and having a jaw at its extremity constructed to move bodily back and forth in the slot, substantially as set forth.

2. A wrench comprising a handle and slotted socket thereon for the nut, a spring-clamp seated adjacent the outside of said socket and having a jaw atits extremity mounted to move bodily back and forth in the slot,su bstantially as set forth.

3. A wrench comprising a handle and slotted socket thereon for the nut, a spring-clamp therefor having a jaw on its extremity arranged to move back and forth in the slot,

and a stop for limiting said movement of said jaw, substantially as set forth.

4. A wrench comprising a handle, a slotted socket for the nut thereon, a spring-clamp mounted with its clamping-jaw, or face to move bodily back and forth in said slot, the handle to said wrench being formed with a circular aperture with a smooth interior surface adapted to receive the operators finger, substantially as set forth.

5. A wrench the handle whereof is provided with a circular aperture having a smoothinterior surface adapted to receive the operators finger, substantially as described and for the purposes set forth.

In witness whereof I have hereunto set my hand and seal, at Washington, District of Columbia, this 14th day of June, A. D. 1902.
