LOUIS P. PARENT, OF WATERBURY, CONNECTICUT, ASSIGNOR OF ONE-HALF TO PETER R. LAROCQUE, WATERBURY, CONNECTICUT.

SPOKE-EXTRACTOR.

Patented Feb. 18, 1908.

Application filed October 14. 1907- Serial No. 397.379-

To all whom it may concern:

Be it known that I, LOUIS P. PARENT, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented anew and useful Improvement in Spoke-Extractors; and I dohereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to he a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1 a side View of a spoke extractor constructed in accordance with my invention, and shown as engaged with a spoke. Fig. 2 a top view partially in section of the device, detached. Fig. 3 a sectional view on the line a-b of Fig. 2. Fig. 4 a rear View, the operating handle being removed from Figs. 2, 3 and 4.

This invention relates to an improvement in spoke extractors, that is, a device for extracting spokes from hubs, and particularly broken spokes, the object of the invention being a simple arrangement of parts whereby the remaining portion of the spoke may be grasped and pried out of the hub; and the in vention consists in the construction hereinafter described and particularly recited in the claims.

In carrying out my invention I employ a head 2 recessed in its upper end to receive an operating handle 3 and formed with a central opening 4-. Pivoted to the lower end of the head is a fulcrum brace 17. Within the head and swiveled in opposite sides thereof are carriers 5 and 6, each formed at their upper and lower edges with gripping fingers 7 and 8 which engage with ribs 9 and 10 formed at the upper and lower edges of gripping jaws 11 and 12 which are free to slide back and forth in the carriers. The outer faces of these jaws taper and at their outer ends are formed with offset arms 13 which have square holes 14 adapting them to be set over the opposite ends of a yoke 15. Preferably the inner faces of the clamping jaws will be concave corresponding to the usual shape of carriage wheel spokes; These aws are provided at their outer ends with lugs 16 which may be turned outward after the jaws have been ontered into the carriers and prevent the withdrawal of the jaws.

In operation the jaws are set onto a spoke and brought to a bearing thereon, the yoke 15 clearing the outer end of the spoke. When the clamping jaws are brought to a close bearing on the spoke, the outer end of the fulcrum brace 17 is lifted to engage with the hub of the wheel, and then force applied to the handle 3 to turn the head outward or away from the hub, and as the s oke is tightly clamped it follows that it wilFbe extracted from the hub. It may here be remarked that as the head is turned by the handle the carriers rock in the head so that a pull upon the spoke is in a direct line and the greater the draft upon the spoke the more firmly the jaws are forced into contact with it. The handle 3 may be removed from its socket when the device is not in use so that the device occupies but small space. The parts may be readily cast so that the device may be produced at a very low cost.

I I claim:

1. The herein described spoke extractor comprising a head, an operating handle therefor, carriers swiveled in opposite. sides of said head, sliding jaws mounted in said carriers, and a fulcrum brace pivoted to the lower end of said head.

2. The herein described spoke extractor comprising a head having a central 0 ening, carriers swiveled in opposite sides tiereof, jaws longitudinally movable in said carriers, a yoke with which the outer ends of the jaws are engaged, and a fulcrum brace pivoted to the lower end of said head.

3. The herein described spoke extractor comprising a head having a central opening, carriers swiveled in opposite sides thereof, said carriers formed with gripping fingers, a pair of tapered clamping jaws having edges engaged by said fingers whereby the jaws are longitudinally movable in the carriers, a yoke with which the outer ends of the jaws are engaged, and a fulcrum brace is pivoted to the lower end of the head, substantially as described.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

LOUIS P. PARENT.
