JOHN I. OWENS, OF LAWLER, IOWA.

BUGGY-WRENCH.

To all fro/ima v' t moy concern lle it known that T, J'oiiN P. Owens, a citizen oit the United States, residing at llawler, inthe county oit Chickasaw and State of Iowa, have invented a new and usettul. lnggydVreneh, of which the `following is a speci tication.

My invention relates to wrenches and more particularly to an axle nut wrench which will remove and replace a carriage axle nut simultaneously with the wheel.

An object, is to provide an axle wrench of light and durable construction, adapted to remove axle nuts of various sizes, and adapted to engage the wheel spokes so that they latter may serve as a lever in removing and replacing the nuts.

WV ith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details ot' construction hereinafter described and claimed, it being understood that changes in the precise embodiment ot the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

1n the drawings accompanying` this specification and forming a part thereof, Figure 1 is a plan view ot my improved form ot wrench. Fig. 2 is a top plan View thereof, and Fig. is a vertical cross sectional view taken transversely et' Fig. 2 and slightly to one side of the lever 25.

e'terring to the drawings in which similar reference nmnerals designate corresponding parts throughout the several views, 10 and 11 are clamping arms pivotally supported to the 'trame 19 by means of the bolts or pins, 14.-, 15. The upper ends oi the clamping arms are vt'm'med with the serrated edges adapted to engage the spokes of a wheel, and the lower portions are bent upon themselves to form the handles 12 and 13. These clamping arms move within the guides 1G and 17 which guides merge into one solid portion 18, upon which portion 1S is secured or mounted the U-shaped spring 20 which is a compression spring and is adapted to hold the handles 12 and 13 spread apart or the portions 10 and 11 into el'igagenlent with the spokes ot' the wheel.

A circular ring 2l is spaced within and rigidly lastened to the trame 19 by rivets or other suitable means, and to this ring is Specification of Letters Patent.

secured the tour sprocket supporting arms lhese arms are bent upward at their lower extremities and rigidly support the socket or axle-nut cap Q3. In order that the wrench may be given a consitlerable range of application, a second socket Q4. is mounted `movably within the socket 23 and should the socket 23 be too .large to properly engage an axle nut, the movable socket 241; is moved :into position to thereby torm a bushing t'or the socket: Q3. This movable socket Q-t is provided with the downwardly extending portion QG with the lug 27 :fastened thereto. To this lng is pivotally connected the actuating lever r1`his actuating lever moves within the member 2S which is provided with slots Q9 and 3() aml a communicating' passage E31 therebetween. VBy means ofthe .lever E25 working within the slots 29 and 30 the movable socket Q-Zl is held in a lowered position as shown in Fig. 3 when the lever 25 is positioned in the upper slot 30' as shown, and in order to hold the socket in an` upward position, the lever 2 is moved within the slot 29 which holds the socket Q4. in a raised position by contacting with the downwardly extending portion 32 ot' the member 28.

The guides '1G and 1T are held in place and supported by the U-shaped members having the upwardly extending arms 33, 34, 35 and 3G. These arms are connected at their upper extremities tothe 'trame 1t), and are riveted to the portion 18 by means ot the rivets 37 at their lower extremities. A U-shaped brace member 3S is rigidly :t'astened to the socket 225 at its upper portion and `riveted to the member 1S at its lower portion. Thus it will be seen that l have provided a structure skeleton in design and at the same time one which embodies rigidity and strength. The herenbe'tore described member 28 is secured to and supported by the member 23S), which latter member is riveted at its lower portion to the member '1.8, and to the 'trame lf) at its upper portion as more clearly shown In the sectional view, ltig. 2l. This member 3S) has a slotl cut therein to allow t'or the movement of the lever 25.

lIn the practical operation oi my device, the handles 'lil and l?) are grasped and drawn together, which action will extend the arms 1,0 and, ll and allow them to be placed between the spokes ot a wheel oi a Patented July S, 1913. Application filed December 9, 1912. Serial No. 735,860.

buggy the axle nut of which is to be removed or replaced. The wrench is then so positioned that the hub of the wheel extends within the circular ring 21, and the axle-nut extends within the socket 23. Should this socket be toolarge for the proper engagement of the nut, the movable socket 24 is moved into position to act as a bushing for the above mentioned socket. The handles 12 and 13 are then freed and the spring 20 acting thereon will force the upper ends l0 and 1l into engagement with and between the wheel spo-kes. By now turning the wheel in a backward direction, the wrench will be rotated and the axle nut accordingly removed. rfhe same operation is repeated in order to replace the nut with the exception that in this case the wheel is rotated in a forward direction which will securely screw the nut upon the axle, as will be readily understood by those familiar with carriage construct-ions.

From the foregoing it will be seen that I have devised a wrench light and strong in construction, and having the desirable feature that it may be applied to axle nuts of various sizes.

Having thus fully disclosed the construction and operation of my improved buggy wrench, what l claim to be new and original with me is z l. ln an axle nut wrench, a frame, a ring positioned therein and supported thereby, a pair of clamping arms pivotally connected to said frame, and held in a clamping position by means of springs, a nut cap supported by said ring, disposed centrally thereof and positioned therebeneath, a pair of guides supported by said frame and said nut cap, adapted to guide and limit the movement of said clamping arms, and a movable cap located within said nut cap and adapted to act as a bushing' for the latter.

2. In an axle nut wrench, the combination of a frame, clamping arms pivotally connected thereto, guides for said clamping arms, a rigidly supported nut cap or socket, a movable cap or socket mounted therein, a lever for actuating said movable cap, and

means for holding said lever in a stationary position.

3. In an axle nut Wrench, a frame, spoke engaging arms pivotally connected thereto, gripping handles at the lower ends of said arms, a ring' disposed within said frame and supported thereby, arms supported by said ring and supporting a nut engaging cap, a movable cap positioned therein, a lever for actuating said movable cap, a member provided with slots having a limited passage therebetween for holding said lever in a stationary position, and guides for limiting and guiding the movement of said clamping arms.

4. A cap for a buggy wrench, comprising a stationary cap, a bushing therefor and positioned therein, said bushing being provided with an extension, a lug carried by said extension, a lever pivotally connected thereto, and a slotted guide member for said lever, adapted to hold said lever in two stat-ionary posit-ions, said positions of the lever corresponding to a raised and lowered position of said bushing.

5. Awrench for buggy axle nuts, comprising a frame, a pair of clamping arms pivotally connected thereto, said clamping arms being substantially bell crank in shape and having handles at their lower extremities, a ring positioned in said frame and supported thereby, U-shaped members supported by said frame and supporting a guide member for said clamping arms, a U-shaped compression spring supported by said guide member adapted to hold said clamping arms in a clamping position, arms rigidly connected to said ring and connected to a U- shaped member, which member is rigidly connected to and positioned centrally of said guide member, Said arms being adapted to support an axle nut cap.

In testimony that I claim the foregoing as my own, I have hereto afixed my signature in the presence of two witnesses.
