speeifieaeion of neaes Patent No. ia-,a'izifaated January-9, Vv185'5.

fTofaZZ 'who/m t may concern Be 'it "known that I, 'OnDiN NICHOLS, of Lowell, county of Middlesex, and 'State of Massachusetts, have invented a 'novel and useful 'Self-Tleeting'Win'dlass and Self-Acting Chaini'Cabl'e Stopper Combined; and I vtruly 'declare that ythe vfollowing description thorough, and 'exactdes'c'riptionfof the making 'and v'of 'the 'manner of constructing `the same in 'generala'nd in detail `and the manner of using them for the purposes above mentioned.

Inreferri'ng to fthe'drawings :Figure 1, dey notes a side elevation lFi'g. 2, denotesia front elevation of the same "device The nature of my 'invention consists of casting out and raising 'the anchor "or chain cable, and fleeting and stopping the said chain by means of a conical grooved cylinder, over which, is placed a pa`w`l or pawls, for the purpose of stopping the chain cable by preventing its slippin'gfaroundithe windlass. The said conical cylinder effectually constituting the windlass for letting out and taking in the cable, and the Apawl combined with the said cylinder foi1 stopping the cable. And also of the other parts of my devices, detailed and fully explained in this specification and the drawings attached to it, and this device or invention, will dispense with the labor of four men in raising anchors; by the chain passing directly from the hawse hole to the windlass and thereby supersede the dragging of the chain up an inclined plane and then over the windlass roll or cylinder, as in other arrangements of windlass and Stoppers.

To enable competent workmen; thor-4 oughly skilled in the art of making, constructing and using windlasses and chain stoppers, to carry out my invention I will describe the saine as follows: I construct a cylinder of wood and iron substantially as seen at B, Fig. 2, of the drawing which must be properly fitted to good substantial bearings as seen at H, Figs. 1, and 2, and they the said bearings, must be firmly secured to the deck and timbers of vessels as seen at A, Figs. l, and 2. At one end of the cylinder is attached an iron ratchet gear, above and into which plays an iron pawl or dog D, hanging freely in the stand E, as seen at Fig. 2, for the purpose of stopping any turning of the before-mentioned cylinder or windlass as is generally used, I further construct and attaehfbyfmeanefef they stanefE, tothefquarter jdeck `or rvother substantial support, two p'awlslasfse'en 'atC, Figs. "l and 2, andi-'at Fig. u 2, fand-funder AIthemu in the,'surfacev 'of `the cylinder, I plac'etwoifronrinfgs'in which series of gradatons, which can =be 'vari-ed a'c'cordn to @the weight of theanchrfand size elf tl e chain, which `are plainly 'shown at Fig. '2. Theis'ef'aire for 'the perfect and free `v'vorkingof the l chain. vUnder `v the yfoy-1inde'r y13, place .two statienaey guiding 'arms 1, I', Fig. 2, 'and-*firmly 'them ter the deck, vffo'r the purpose o'f 'ip'roperly guiding the chain Vas yit 'passes "o'n, 'or dif fiol', tlie cylinder. The right one briiigs the chain partly '0H the ed'ge of theJ first grada#- tion of the cylinder and consequently, the rest ofthe chain coil follows a similar course on the other gradations. And I also construct two movable adjustable arms, as seen at J J, Fig. 2,'held in their working positions by the stops 0, Fig. 2, the one at the right hand is for the purpose ofelfectually guiding the chain, into the groove L, continually, as it is drawn into the vessel. And the left hand one effectually throws the chain out of theJ groove N, as it passes around the cylinder so as not to ride or come in contact with itself, when it passes out of the ships or vessels. These movable adjustable guides, should both be made of iron, and freely slide between two strong ways, or tracks, as seen at Fig. 2.

I design to make two holes in the deck or other equivalent devices for the purposes of keeping the guide J J, close to the surface of the cylinder, and guiding the chain into and out of these grooves as required, and at the same time to keep the left hand guide from the surface of the cylinder. And when the chain is to be let out, the right hand adjustable guide is moved from the cylinder and thus held fast by the stop o, and the left j hand adjustable guide is moved to the surface of the cylinder and held fast in that position by the other stop 0. It must be understood by this contrivance that the top part of the said guides J, kee lthe chain in the proper position so as to e stopped by `the bows of the vessels.

the pawls, when it is let out or drawn in. It will be further understood that the chain winding several times around the cylinder can be stopped much easier by the pawlM, than it could by the letting the pawl C, drop on to the said chain which would bring the wholel strain upon it and the cylinder. And my invention supersedes the necessity of strengthening the vessels at an outlay of from one to two hundred dollars which is necessary in all other stoppers placed upon And having thus described the making and construction of them I will describe the operation as follows:

The chain K, and all the other parts as shown in the drawing are in the position as when the cha-in is being drawn in by the turning of the windlass B and if the chain islt out from the vessel the right hand Ysliding guide must be removed from the surface of the cylinder and the pawl C, must be raised from the chain which immediately changes its positions from the right end to the left end of the cylinder B, by the revolving of the saine, which is effected by the weight of the chain and anchor, by turning the said cylinder, and when thus vchanged to the left end of the cylinder B, the left hand sliding guide J, ismoved up to the surface of the cylinder, and secured in that position by the stop o. Thenthe chain can be let out its Whole length without its being possible for any part of the chain to come in contact with itself when passing out of the ships or vessel as set forth and also when the chain is being drawn in. All essentially as set forth and specified.

Having thus described my invention, what I claim as my original discovery and desire to secure by Letters Patent is* i l. The cylinder' B made substantially, and operated essentially and for the purpose as set forth.

2. I claim the action and coperation of one or more pawls with the cylinder B, so arranged with this cylinder as to come in contact with and firmly hold the chain, when passing either way over the top of this cylinder which constitutes, with the pawls C and M, both the windlass and stopper when constructed and operated essentially as set forth.

3. I claim the combination of the cylinder B, the pawls C and M, and the adjustable guides J, all or either two of them, for raising, stopping, and eeting chain cables, they being Vconstructed and operated essentially and for the purposes set forth.
