CHARLES PERLEY, OF'NEVV YORK, N. Y.

COMPOND CAPSTAN FOR SHIPS.

iSpecication forming part of Letters Patent No. 17,940, dated August 4, 1857; Ressued October 7,

To all whom t may concern:

Be it `known that I, CHARLEs PERLEY, of the city, county, and State of New York, have invented, made, and applied to use certain new and useful Improvements in Means for Vorking Chain Cables, which I Ydenominate lthe Compound Capstan Windlass; and Ifdohereby declare that the following isa full, clear, and exact description of the construction and operation of t-he same, reference being had to the annexed drawing, making part of this specification,

. wherein- Figure 1, is a plan of my apparatus with the capstan and one heaver removed to show the gearing and other parts, the base being shown as partly broken open for the same purpose. Fig. 2, is an .elevation of the app paratus with one heaver operating on a chain, while the other is disconnected. Fig.

A3, is a cross section through one of the heavers. Fig. 4, is a plan, and Fig. 5, is a vertical section of the capstan head, showing the manner of connecting and disconnecting the `apparat-us and go to another, that vis to say, the main capstan, t-he windlass and a power capstanshould be worked either separately lor connectedly from one handspike head.

Others have before sought to attain this object; my invention therefore, although possessing the before mentioned requisites,

does not consist in combining a capstan, Windlass and power Winches together, but in all other apparatus with which I am acquainted, if the wei ht or strain of the chain be on the wind ass when riding at anchor or at other times, the power capstans or other parts have to be revolved with all the friction due to said strain or weight.

My invention consists in constructing and fitting a windlass in such a manner that the shaft is constantly relieved of the weight or strain of the cable, and has simply to rotate the said windlass when connected to said shaft; and in combination with said windlass, thus relieved from strain on the shaft, I make use of a peculiarly constructed power capstan that can be used simultae. This capstan c, may be immediately above the base a, or be located on the forecastle or hurricane deck, the shaft b, being extended vertically for this purpose.

The capstan barrel c, is to be fitted so as to revolve on, but independent of, the'shaft b, by means of handspikes in the sockets j, and the barrel is to be sustained on balls or otherwise to support its weight, and relieve friction.

d, d, are the pawls and e, is the pawl bed as usual.

g is the capstan head, keyed into the end l of the shaft b, see Fig. 5, and the head g and barrel c are to be 'connected together when it is required to rotate the shaft by means of sliding blocks 2, 2, set in the slides 1, 1, in the top of the barrel c, and said blocks 2 are provided with' tongues. passing through mortises around the handspike head terminating with rings 3, 3; and around the inside of the head g notches 4, 4, are provided so that the barrel and head are connected permanently by sliding the block 2, 2, out-ward into the notches 4, 4, which notches being near the largest part of the head, act with the best leverage in rotating the shaft b.

Near the lower end of the shaft b, is a gear wheel L, taking two intermediate gears z', z', to the wheels k, 7c', all within the base a, and the wheels 7c, 7c, are on the short vertical shafts Z, Z. Both of these shaftsl, ZY, are to be used where two heavers are fitted to my apparatus, but where only a single heaver is used one shaft and its gears may be dispensed with; and as both heavers are alike, and operate similarly, I shall only describe the construction and operation of one.

The shaft Z, is set in a step 5, and is formed square to receive the wheel ic and vother parts.

6, is a bearing for saidshaft Z, in the cover of the base a, and said bearing is formed as a square opening (although it might be round if the wheel 7c, were keyed onto a round part inserted through the bearing 6,) and the square shaft Z, is turned round at this part, and also for the length of the beaver m, which is formed with a square hole and is dropped over the square upper part of the shaft, but said shaft can rotate in the beaver without turning the same because of the shaft being round as before mentioned.

n is a small capstan barrel formed with a square hole fitting the said shaft Z, and rotated with the same, (or a slot and key might be used instead of the square shaft).

9 is a square formed on the lower end of the barrel n, taking a similar square in the beaver.

7 is a ring by which the barrel n can be lifted sufliciently to clear the square coupling 9 and disconnect the beaver, in which case the pin 8, is inserted through ha second hole in the shaft Z, or over the upper end of the same to sustain said head, and when in this position the said barrel n, can be rotated independently of the heaver to form a power capstan, or act as a bit receiving a rope or chain; o-r when lowered so as to couple (at 9) with the beaver m, and the pin 8 inserted through a hole in the shaft Z, so as to hold said coupling together, the said barrel n, rotates said beaver m, in either direct-ion, according to which way the capstan is turned, and either draws in or gives out the chain as neXt set forth.

The beaver m, is of a size and shape to receive correctly the chain with a given sized link, and said beaver can be lifted 0H and another substituted, adapted to a different chain, should the same be required, or where double beavers are used one side may be fitted for one chain, and the other for a lighter or heavier cable: in all cases the beaver is to be formed with a deep groove at m, which takes one side of the horizontal chain, and is to be turned olf, or otherwise trued at the bottom of said groove, so as to receive the thin curved projecting end of the bearing block 0. This block 0 is set in slides p, and provided with a block 11, (or its equivalent a slot) against which the wedge 10 acts, to set the block up against A the beaver at to sustain the same, and relieve the shaft Z, and other parts from strain by the chain; so that the vessel can ride at anchor with perfectsafety by this beaver; and to avoid any risk of slipping, the chain g, may be seized together forward of the beaver and bearing block. When the beaver has to be removed the block 0, is slid back as seen on one side in Fig. 1.

The chain cable may be led into the locker pipe as at 1, or be brought around any suitable friction roller, and carried farther aft before entering the locker pipe.

In order to afford additional security in working the chain I form troughs for said chain to move in on each side of the slide Z9. By flanges 12, 12, and in said troughs I hang pawls s, and t, set and moving on pins 18, so as to prevent the chain slipping back as the same is drawn in. These pawls are to be thrown over when the chain is running out; and said chain can be run out by simply lifting the capstan coupling (n) without taking the chain out of the beaver.

14, 14, are belaying pins which may be inserted if desired.

The combined operation of the parts, as well as their separate functions, will be vfully apparent from the foregoing; and it will be seen that the capstan can be used in the ordinary manner. The small barrels can be used as power capstans or bits. That one or both beavers can be used simultaneously with or separately from the other parts. rIhat the chain can be taken in or given out on either side. That all strain is removed from the shafts so that the vessel can ride at anchor with the chain around the beavers, and still the windlass is effective for other uses. The various other advantages of my apparatus will be apparent to nautical men and need not here be specified.

I do not claim a capstan, windlass and winch combined; neither do I claim a bori- Zontal heaver in itself, butd What I claim as my invention and desire to secure by Letters Patent, is-

1. rlhe combination of the adjustable bearing block 0, with the beaver or windlass m, so constructed as to receive the strain and weight of chain cable and relieve the shaftI Z, therefrom, leaving said shaft Z, when disconnected from said beaver or windlass free to rotate and be used for other purposes without loss of power by the friction of said beaver or windlass, even when the vessel is riding at anchor by said, beaver substantially as and for the purposes specified.

2. I also claim the power capstan n, and its coupling 9, fitted to slide endwise of the shaft Z, combined with the beaver or windlass m, and bearing block o, whereby the said power capstan n, connects the shaft Z, and beaver m, or is itself free for use as a power capstan or bit when connected to or disconnected from said beaver or windlass m, substantially as and for the purposes specified.

In witness whereof I have hereunto setmy signature this ninth day of February 1857.

CHARLES PERLEY.
