specification of'riette'rs Patent No. 75@ dated' my ao, 183s yTo all whom it mayv concern:

Be it known that I, RUSSELL Evans, of

' Madison, inthe county of New Haven and time.

. poses, which is cables, or ropes.

State of-Connecticut, have invented anew anduseful improvementl in windlasses for raising anchors and other heavy `bodies and in'winches for raising sails and putting 1n and taking out cargoes 'and -for other pur- 'described 'as follows, reference'bei-ng had to the annexed drawings of. the same, making partpf thisspeciiication.

This improvement consists in placlng a metallic cylindrical shaft or axle A Figure l, in a horizontal position revolving 1n metallic boxes, in uprights, standards, or b1ts` B B B, said axle extending beyond the two outside standards to receive a head D' secured on the same by bolts, the extremltles extending beyond said heads to receive a lever F and pawl G for turning 'said-head -and axle.

Each lever is pierced near the end lwith a Vround'aperture Hthrough which the'end of the laxle passes. The pawl is placed about one third the length of the lever from the end containing the aperture. It 'falls mto the notches of a cog wheelI, secured on the end of the heads 'for turnin the same with the axle, The heads are liewisemortised to receive 'common hand spikes 1, if preferr-ed, or for the purpose of uslng `these as well as'the '.lev'ers and pawls at the' same On the axle between the standards and revolving loosely thereon are placed the barrels L L around which are wound the chains,- These barrels are boxed in the. centerv with metallic boxes and are mortised on the outside for common handwith the usual ratchet N, for preventingtliem from turning back. The'pawls are attached to the sides of the standards. O n the axle, at each end of the barrel, is fastened a small cog-wheel or pinion O, Fig.' 2. This cogspikesand furnished wheels M and pawls 'wheel works into another similar cogwheel P, turnino on a pin -inserted into the side of the, standard. Said last mentioned cog wheel works into co s formed around the inside of a largehol on the end of the barrel and turning with it.

Similar cog-Wheels are placed at each end of the barrels, and all of them are placed in recesses or depressions made in the ends ofthe barrels by which they 'are protectedfrom the weathen ow wheel Q, fastened When a heavy anchor or weightis to be raised the lever is put 'onf the ends of the axle, thepawl of said lever brought into the notches of the ratchet wheel on the -end of the hub, the lever depressed which being locked with the ratchet wheel causes the hub and axle to turn, which turns the small cogwheel fastened on it and this the other small cog-wheel turning on the pin in the standard, and this the largecog-wheel on the end of the barrel whiclrturns' the barrel with aI slow motion, but a greatly multiplied power,

and lthus winds up the cable and raises the anchorV or weightV attached to it. All the cog-wheels and barrels are acted upon in the Same manner.

The lever is then raised and-a new hold taken with the pawl and the 4operation repeated. The hand spikes may also be used at the same time` or either may be used separately. The motion of the bar- V-j rels will be the reverse of that of the hubs.

At the commencement of the opera-tion', or

when a light strain is required, the hand spikes may be applied directly to thebarrel in the usual manner whenthe motion will be'quic'k but less powerful andthe action will of course be similar to the common windlass."

l 4The Winch, Fig. 4, which is to bexused generally f or hoisting sails, discharging cargoes, warping vessels, and for such like phrposes,. is constructed on a similar principle to that of the wlndlass above described V-except that no handspikes or levers are used,

but simply a winch S which is applied to the endof the axle T when a slow' and powerful action is required; and to the end of .the barrel at U where a quick motion is to be obtained. The barrels in this case` are secured to the' axles! by means of washers V screwed on the ends of the axles; and the cog wheels and pawls for preventing the return of the barrel are inside the standard andl all the parts of the gearing are rotected from the weather as in the wind ass. The invention claimed andv desired to be Secured by'Letters Patent consistsv iii-.-V

The mode of gearing, connecting andoperating the windlass, the respective parts being combined. and arranged substantially in the manner described, Said parts taken individually being disclaimed RUSSELL EVARTS.
