POWER-WIN DLASS.

SPECIFICATION forming part of Letters Patent No. 276,988, dated May 1, 1883.

Application filed Deccinber 18, 1882. (No model.)

1' 0 all whom it may concern Be it known that we, HERMAN VVINIER, of the city of Brooklyn, county of Kings, and State of New York, and FRANK S. MANTON, of the city and county of Providence, in the State of Rhode Island, have jointly invented certain new and useful Improvementsin Power- Windlasses; and we do hereby declare that the following specification, taken in connection with the drawings making a part of the same, is a full, true, and exact description thereofi.

Our invention is intended principally to remedy the difficulties which have. heretofore existed from the want of a single unyielding bed common to the engine and the Windlass which it works.

Heretofore the Windlass has been usually located upon the main deck, and the engine for driving it bolted to the under sideof the upper deck. Sometimes, however, the windlass has been located upon the main deck and the engine bolted to the under side of the main deck, in which position it is necessarily inconvenient of access. Under either plan there is great liability of the disarrangement of the worm-gear which connects the windlass and the engine, as the result of the springing of the deck from the various accidents to which sea-going vessels are exposed. Besides, too, the strains to which the whole apparatus is subjected in working are irregularly distributed, from the fact that the two machinesthe Windlass and the engine-are not constructed and put together as an entirety.

The characteristic featurein the construction of our improved power-Windlass is that the Windlass and the engine which drives it are mounted upon the surface of and secured to a single bed-plate which is common to both, and also the wornrshaft which is driven by the engine Ed which connects the Windlass with the enggne is located in a horizontal instead of in a vertical position, and so that the axis of the worm-shaft is parallel, or nearly so, with the line in which the anchor-chains pull in passing over the wild cat to the hawse-pipes when the anchor is being hove, instead of being at right angles, or nearly so, therewith, as under the former arrangements referred to.

Another feature of our improved construction is that the worm-shaft is journaled in the pawl-bit, or .in an equivalent standard connected with the common bed-plate, so that the strain upon the worm-shaft in the direction of its axis in working the windlass is transmitted to and distributed throughout the common bed-plate of both engine and Windlass; and our improvement further allows the pawl-bit itself, which is always a necessary adjunct of a Windlass, to be utilized for resisting the strain upon the worm-shaft, whether the same is mounted on the bed-plate or not, and also the pawl-bit itselt'can be made hollow, and the hollow space serve as a housing for a portion of the ratchet-gear for the holding-pawls and other gearing adjacent thereto, whereby great economy in the space occupied by the engine and Windlass is obtained.

Figure l is a plan or top view of our windlass complete. Fig. 2 is a side elevation'ot' the same. Fig. 3 is a side view illustrating a modification in the arrangement and location of the worm-shaft.

In the accompanying drawings, A represents a bed-plate of iron or similar suitable unyielding material, the area of which is sufficiently great to accommodate the engine, the windlass, and its bits, as hereinafter described.

The engine, the side bits for the Windlass, and the pawl-bit are represented by the letters B, G, and 1), respectively, and all are rep resented as firmly bolted to the common bedplate A. The Windlass-shaft E and the wild cats F F are driven by a wormgear, the wheel ct of which is mounted on the Windlass-shaft, and the worm I) of which connects the shaft of the engine with the Windlass, as is well understood in the construction of power-vindlasses. 0

In the arrangement shown at Fig. 1 the engine is located opposite to the pawl-bit, and the main shaft of the engine, with the wormscrew attached thereto, is parallel with the face of the bed-plate. One end of this wormshaft is journaled in and supported by the pawl-bit, and as the latter is necessarily made of great strength, so as to resist the pull of the vessel when riding at anchor, it is apparent that a complete resistance against any tend- IOO ency to a longitudinal movement on the part of the worm-shaft will be furnished when the windlass is undergoing the labor of getting up anchor; and it is also obvious that the line in which the anchor-chains pull in passing over the wild cats to the hawse-pipes when the anchor is weighing will, under this arrangement of the worm -shat't, be parallel, or substantially so, with the axis of the worm-shaft-. All the strains to which the apparatus as a whole is subjected will, by the use ot'a common, bedplate, be distributed throughout the whole 'apparatus, including the bed, and the engine and the Windlass be always kept and preserved in proper relation to each other. Besides, too, the Windlass and the engine can be properly erected as an entirety at the shop where it is constructed, and the inconvenience and disadvantage resulting from the necessity of adjusting the position of the engine relatively to the Windlass on board ship is avoided.

In Figs. 1 and 2 the shaft of the engine is represented under an arrangement in which.

the cylinders of the engine are located near the bed-plate, and the crank-shaft and its extension into the worm-shaft located in line with the top of the worm-wheel. A modification of arrangement is represented at Fig. 3, in which the relative position of the cylinders and the crank-shaft is reversed, so that the worm-shaft extending from the crank-shaft is near to the bed-plate and in engagement with the worm-gear at its under side. In both of these arrangements the engine is located upon the main deck in close proximity to the windlass, and so that all its parts are readily accessible, instead of being ditfieult of access, as it has heretofore been when hung from the under side of a deck.

The pawl-bit l) is made hollow, and thus, while furuishinga greater amount of strength for the same amount of material, enables the holding-pawls a and a portion of the wormwheel a, the ratchet-gear G, and the bevelgear H, for working the capstan, to be housed therein. By this arrangement the holdingpawls are entirely ineased, as shown in Fig. 2 and protected from displacement, and the amount of space required for the Windlass and its pawl bit is greatly lessened.

hat we claim as our invention, and desire to secure by Letters Patent, is-

1. The combination, in a power-Windlass, of the windlass and its driting-engine by means of an iron bed-plate common to both Windlass and engine, and a worm-shaft driven by the engine and engaging with a wornrwheel on the shaft of the Windlass, the strain upon which worm-shaft in working the Windlass is transmitted to and resisted by the com mon bedplate, substantially as described.

2. The combination, in a power-Windlass, substantially as hereinbefore set forth, of the driving-engine and the Windlass, when the worm-shaft, which transmits the power from the engine to the windlass, is arranged with its axis parallel, or nearly so, with the line in which the anchor-chains pull in passing over the wild eats when the anchor is being weighed, and is journaled in the pawl-bit of the windlass.

3. The combination of the hollow pawl-bit with the ratchet-wheel of the Windlass, whereby the said ratchet-wheel may be partially housed by the bit, and economy in the space occupied by the windlass and bit may be secured, substantially as described.
