WINDLASS.

SPECIFICATION forming part of Letters Patent No. 237,885, dated February 15, 1881.

Application filed August 18, 1580. (No model.)

To all whom it may concern Be it known that I, FRANK S. MANTON, of the city and county of Providence,'and State of Rhode Island, have invented a new and useful Improvement in Windlasses; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to an improvement on that part of the Windlass known in the art as the wild-cat, and it consists in providing such a wild-cat with sockets or receptacles into which a bar may be inserted, so that the wild-cat can be turned when disconnected from the driving-shaft, as will be more fully set forth hereinafter.

Figure l is a view of part of a Windlass, showing the end standard, the driving-shaft, the driving-head, and the wild-cat, the latter two being shown partly in section. Fig. 2 is a view of part of the wild-eat, the flange ofwhich is shown provided with sockets. Fig. 3 is a perspective view of a bar used for turning the wild-cat.

In the drawings, a represents the end standard, in which the driving-shaft b is journaled.

c is the driving-head, firmly secured to the driving-shaft 1).

dis the wild-cat, which is loosely mounted on the driving-shaft, and is constructed so that the same may be locked to or unlocked from the driving-head c.

e is the flange on which the brake-strap bears, by which the wild-catis controlled when payin g out cable. f represents the opposite flange of the wild-cat.

When a chain is to be secured to the anchor or disconnected from the anchor, and when-' the periphery of the flange f, as is shown in Fig. 2, so that the bar shown in Fig. 3 may be inserted and the wild-cat turned by the same.

The end z of the baris made to enter the sockets k of the locking device, and if the sockets in the wild-eat are made of the same shape the same end can be used to secure the bar to the wild-cat; or if the sockets are made as shown in Fig. 1, then the other end, h, of the bar is made, as shown, with a fork to pass over the flange f.

WVhen the chain has been properly adjusted the wild-catis connected with the driving-head by means of the locking device and power is applied to turn the wild-cat, or when the chain is to be paid out the wild-cat is left unconnected, and is controlled by means of the friction-brake. The bar is therefore used only from time to time to adjust the chain, and it is desirable that the same bar by which the locking device is operated should be used to partially turn the wild-cat.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the driving-shaft of a Windlass, of a wild-cat constructed to be connected with and disconnected therefrom, said wild-cat being provided with sockets for receiving a bar for rotating a wild-cat, substantially as set forth.

2. Thecombination,withthe wild-catd,loose- 1y mounted on the driving-shaft, and arranged to be connected with and disconnected from the same, of flan ge f, having the sockets g 9 constructed to receive the bar, by means of which the wild-cat can be turned, as described.
