T aZZ whom it may concern:

Beitknown that I, HOWARD THOMAS GAY- (TON, a subject of the Queen of Great- Britain,

' 'this specification, and in which- Figure 1 is a front View of my improved Windlass. Fig. 2 is a rear view of the same. Fig. 3 is a side View; and Fig. 4 is a perspective detail view of one of the pawl arms or boxes, showing portions of the same broken away.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to windlasses,and more particularly to windlasses adapted to be used on board of vessels for lifting the anchor; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letters A A indicate the two upright posts between which the drum B or barrel of the Windlass is journaled, and 0 indicates the upright post which is placed forward of the Windlass and upon which'the operating mechanism is secured. The upper end of this post is formed with two perforated lips. D D, between which a lever, E, is pivoted at its middle upon a bolt, F, and the ends of this lever are socketed for the reception of two handles, G G, which have their inner ends secured in the sockets by means of pins H. Two large cog-wheels, I I, are journaled upon the sides of the central upright upon short shafts projecting from the same, and the outer faces of these cog-wheels have ratchet-wheels J J secured to their central outwardly-extending hubs, so as-to leave spaces between the cog-wheels and the ratchetwheels, and the faces of these ratchet-wheels are formed with outwardly-projecting flanges K at the rims, the rims being wider than the bodies of the ratchet-wheels. Hollow boxes or arms I. have their inner open ends clamping the sides of the ratchet-wheels, and the edges of the sides of the boxes are cut out segmentally and formed with inwardly-projecting flanges M, which fit inside of the projecting rims of the wheels and secure the boxes to the ratchet-wheels, while the wheels may revolve freely within the open flanged ends of the boxes. Pawls N, of which three are shown in the drawings, although a greater or smaller number may be used,are pivoted with their inner ends upon bolts 0, secured transversely in the boxes, and engage the forward rims of the ratchet-wheels, and the outer ends of the pawl boxes or arms are provided with suitable eyes, P, to which are pivoted the lower ends of rods Q, pivoted at their upper ends to the ends of thelever. It willthus beseen that the ratchetteeth upon the forward edges of the wheels facing downw ard,-and thepawls pointing upward and swinging upward, the said pawls will engage the ratchets and revolve the wheels when the outer ends of the boxes are raised, the boxes having their fulcra upon the circular flanges bearing against the annular rims of the ratchet-wheels, and the outer ends of the pawl-boxes are raised alternately by rocking the lever upon the top of the upright by means of its handles. The cog-wheels connected to the ratchet-wheels engage small pinions R,secured upon the outer faces of large cogwheels S S, journaled upon short shafts T, projecting from the upper end of the upright, and these cog-wheels in turn engage small pinions U, journaled upon short shafts V V, projecting from the sides of the upright. These pinions engage cogged rims upon the drum of the Windlass, the said rims W W being embedded in the surface of the drum, and it will be seen that the sides oltheannulargrooves formed by thus embedding the cogged rims in the surface ofthe drum ofthe windlass will serve as guides for the pinions U, and cause them to engage squarely with the cogged rims W W. A 95 cogged rim, X, is secured upon the middle of the drum, and this rim is engaged by the notched or cogged lower end of a bolt, Y, sliding in vertical bearings Z upon the rear side of the upper end of the upright, and the said 100 bolt will be raised by the cogs of the rim when the Windlass is revolved with its upper side when the drum is revolved in the opposite direction, which only can take place when the bolt is raised out-0f engagement with the cogged' rim.

The pawl-boxes are preferably made in two pieces. the side pieces of the boxes being formed with flanges at their edges, which fit upon each other. transverse bolts securing the two halves together, the said' construction enablingt-heboxes tobe conveniently fitted upon the ratchet-wheels and removed from the same.

It will be seen that on each movement of the end of the reciprocating lever E its box Lwill be raised, and, as previously described, partially revolveitsratchet-wheel J, and the large cog-wheel I, keyed on the same short shat't, will also be partially revolvedthat is, turn for a portion of a revolution and this partial revolution of the la rge cog-wheel I will impart an entire revolution or more to the small pinion R. with which it meshes, and as the said small pinion R is secured concentrically to the side ot'the large cogwheel S, the said large cog-wheel S will also be revolved for an entire revolution or more, and this large cog-wheel S, meshing with the small pinion U on the shaft V, will, on making one revolution, revolve the small pinion U three or more times, and this small pinion U, engaging directly with its cogged rim V on the drum of the "windlass, will turn the Windlass with great speed.

It will be seen from the foregoing that by this peculiar construction and arrangement of operative intermeshing parts each movement of each end of the lever E will impart great speed to the Windlass, and thus enable a cable to be wound up with great rapidity-a most decided advantage inapparatus' of this class.

Having thus described myinvention, I claim and desire to secure by Letters Patent of the United States- In a windlass, the combination of the drum having cogged rims near its center, and having also a central cogged rim, a pawl-bolt engaging the central rim, the large cog-wheels having ratchet-wheels secured to their faces at a distance from the same, the small pinions meshing with the said large cog-wheels and rigidly secured to the sides of large cog-wheels, and the small pinionsintervening between the said large cog-wheels and the cogged rims on the drum of the windlass, pawl-boxes having segmentally-cut-out inner ends formed with flanges engaging the projecting rims'ofthe ratchet-wheel, and having pawls between their sides engaging the teeth of the ratchet-wheels, a lever having handles at its ends and pivoted transversely above the cog-wheels, and con- 'necting-rods pivoted to the ends of the lever and to the outer ends of the pawl-boxes, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses/ A HOWARD THOMAS GAYTON.
