SPECIFICATION forming part of Letters Patent-N0. 299,048,:3ated May 20, I884.

Application filed February 16, 1884. (No model.)

To ctZZ whom it may concern:

Be it known that I, Al\IBROSE AMIRo, a resident of Pubnico, Yarmouth county, Nova Scotia, Canada, have invented a new and Improved Ships \Vindlass, of which the following is a full, clear, and exact description.

My invention consists in certain improvements in that class of windlasses which employ a centrally-pivoted brake-lever, to which two pawls are pivoted, said pawls engaging ratchet-wheels for operating the windlass, as will be hereinafter fully described, and specifically set forth in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improved Windlass. Fig. 2is a front elevation, and Fig. 3 is a sectional elevation.

Alongside of the middle portion of the drum a of the Windlass I arrange a horizontal shaft, Z), in a suitable support, 0, on each end of which shaft are a ratchet-wheel, d, and a gear-wheel, e, and to each ratchet-wheel I provide a driv ing hook'pawl, f,connected with ahand-brake lever, g, which is pivoted at its center h and between the pawls to the support 0 a suitable distance above the shaft of the ratchet-wheels to enable the brake-lever to be placed at the proper height to be worked by men stationed at each end of the said brake-lever. These pawls are forked at their lower ends to form guide-flanges f, to embrace the sides of the ratchet-wheels and prevent the pawls from lateral disengagement therewith. The drivewheels 0 are in this instance geared with the drum of the windlass by intermediate wheels 2', fitted on an intermediate shaft, j, and the wheels 70, fitted on the drum.

The intermediate wheels, 1', may be dispensed with, if preferred, and wheels 6 be geared directly with the wheels 7c,- but it is preferred to use said intermediate wheels for turning the drum in the direction best suited for the work of the Windlass.

It will be seen that in the arrangement of the brake-lever and ratchet-wheels the brakelever ranges parallel with the drum of the Windlass compactly, and without being we tended in greater length than the drum, and affords a simple means of applying great power to the working of the Windlass.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the centrally-pivoted lever g, and pawls f, pivoted thereto at their upper ends, and formed with hooks and guideflange at their lower ends, with the ratchetwheels and mechanism for connecting them with the drum of the Windlass, substantially as set forth.

2. The hand-brake lever g, pivoted at the middle to the support 0, located at the side of the drum a and midway between the ends, and having a hook-pawl, f, each side of its pivot, said pawls being forked to form guide-flanges f, in combination with a ratchet-wheel, d, for each pawl, geared with the drum or of the Windlass through the wheels 6, intermediate wheel, 1', and wheels k, substantially as described.

AMBROSE AMIRO.
