IMPROVEMENT 1N Win 131.Ass'zzs.v

l `The Schedule reterred to these Letters P atent and making part of thc. same v Beit known 'that I, ALBEET RUSSELL, of-Newburyport, inthe county of Essex-and State'of Massa-v chusetts, have invented a `new and useful 'Improvemeut in Machinery for Operating the Windlass of a Navigable Vessel; and I do hereby declare the same tobe fully described ,in therfollowiiig Specification and representedin the accompanying drawing, ot' which-- Figure 1 is a topjview, and y Figure 2, a. sidefjelevation of'a'I win'dlass vprovided :with my invention, henature of which 4consists in a special arrangement and'eombination, in the manner as setforth, of two 'disconnected brakes orl operative levers with the pawlLcases of the windlass'. In the drawing-. Y i A denotesthe windlass; 4B and C, its two` pawlf-cases or working pawl-carriers; `and ,i j,

D D, its ratchets, constructed and applied together in' the usual manner, thefsaid pawl-cases being `arranged in the'eommon way, with a post, E,between them.

Above the deck or platform F,disposed over the main deck G' and over the pawl-cases, I arrange, in

The shorter arm of" each lever is slotted, as shown at a, to receive one of the connection-rods b I1 of the .pawl-cases, the lever being connected to such rod by apio, c, going through both.

Byseamen takinghold ofthe longe-x` arm of each of 4the brakes or levers, and rnoving `it-up and down, each pawl-case will have a reciprocating or vibratory move- Y the rods, is employed. Or instead ofsuch, two levers,

connected by an intermediate lever and supported by vbratory posts, are used, such beingjasshown in the patent No. 16,000, 'rautedNovemb'er-, 1856, to

Christopher Amazeen.

l"The advantagesoi' two independent brake-levers,

one to each pawl-case, as represented in the drawing, are that such admit of the windlass being-worked b v one of the brake-levers without the other being moved I oriutert'ering iu any way with the operation of the -first.V rIhey also admit of both pawl-cases being worked in the same direction at once, thereby enabling the .operatives to exert their power with better ormore useful effect, There are other important advantages possessed by the employment of independent levers with separate fulcrums, as it admits-of longer levers being used; These can well be employed when two levers are connected by a. third, as in the Amazeen windlass. i

I, therefore, elaim The two disconnected levers orjbrakes, combined vand arranged, as explained, with the win'dlass and its ratchets and their pawl-cascs, the whole` 4being to operate substantially as specified.
