IMPROVEMENT m corrou-raesses.

the Schedule "(and to in than Loreen Patent and making put of them.

To all whom it may concern drawn downward by means of a chain passing through thegroove of a clutch-wheel, and is raisedby cords connected with an independent Windlass.

The invention consists principally in a drop-chain.

Jreld by the'side of aadbeneath a clutch-wheel, by means of a device called a spoon, for the purpose of preventing the links from slipping out of the clutch wheel, said spoon being so'arrauged it may readilybe' made to drop by its own weight away from the clutchwheel, and thus release the chain therefrom.

'. The invention also consists in a device for preventing the chain from rising in the groove to the-oppo--- siteside of the clutch-wheel from the s mon-aforesaid; also, in a device for preventing the chain from lllll'lh ing while it is running in either direction; also, in

rubbers attached to the follower in such a manner as to steady the same in itsmotion upon its guides, and to prevent the latter from being forced outward by the material in the press, said rubbers being so shapedas to allow the follower to tilt as much as maybe necessary; also, in an arrangement whereby the same rope and Windlass that raise the follower are used to draw it'forward into position upon its guides in the press-box, afterthe follower has been drawn back in the usual manner upon the guide-ways at the top of the pressbox, in order that it may be out of the way,

at the cotton while the latter is being placed in the -In the-drawing- A is the press-box.

a-, the follower-bar. I ,7

.b b, the chains by which the followeris lowered, the manner of operation of which chains being well known it is not necessary to describe.

c c, grooved sheaves near the ends of the followerbar, over which the chainsb i'dn.

(I (I, the clutch-wheels, which are fixed on shafts e0 between parallel beams ff, that project horizontally from each end of the press-frame, in these beams the shafts 0 being mount-e h, the spoon, by which, when it is pressedagainst he periphery, the chain 1: is confined int-he grooveof the clutch-wheel. Each spoon It has a concave face which fits the periphery of the clutch-wheel.

The spoons are pivoted between lugs i, which extend toward each other from the inner sides of the beams f.

In fig. 1, k are levers, each of 'which is jointed at one extremity into one of the beams f, and which may be turned over the outer ends of the spoons h into grooves made for thereception of each lever in the outer end of that one of the beams f to-which the lever is not jointed. When the levers are thustnrned into their groove over the spoons the latter are held in contact with theclutch-wheels. When the levers k are turnedwoffrom the spoons h, the latter, beingbars on that are attached c'ross-wiseto the upper sides of the beams f. The fingersl extend into the grooves of the chitel'z-wheels and prevent the"chain's from rising therein to points opposite the spoons h.

In fig. 1, n are blocks fixed in the outer ends of thefollower-bar a. k I n; are grooves cut in the inner faces oft-he blocks a, which grooves .the chains b partially enter as they move up or down, bythese groovesl said chains being kept from twisting. e

.ln,fig. 1, on are vertical posts at the ends oi the press-box, which posts pass through the central groove. of the follower-bare and serve as guides for the same, and also to prevent cotton't'rom oozing out at theends of the press-box while the follower is descending. I

-r r are rubbers, fixed in the bare in contact with the outer sides of the guides 0. By the rubbers 'r the follower is steadied in its movements on the guides,

and the latter are also held against the outward pressare 'of the cotton. The'rubber's are made convex in form on the sides next the guides 0, so as to admit t are cords,fastened at one extremity to the windlass a, passing thence up over sheavesu in the topcross-pieces c of the press-frame thence over sheaves a in the same cross-pie'ces; and thence downward to the follower bar-a, to which the opposite ends of the cords are secured.- 0n turning the wind'lasss the follower is raised by means of the cords t. the top of the press-box and clear of the-guides o, the follower is drawn aside upon the guicle ways w, fig. 2, so that it may be out of the way when a fresh supply of cotton is placed in the box.

The press having been recharged, it is necessary Arrived at.

that the follower should be drawn over the box. This is done by turning the windlass s in the same direction in which it was turned to elevate the 'iollowr,

the arrangement being-such that when the follower. is drawn back upon the guide-ways a: the motion of the Windlass is thereby reversed, so that to draw the follower over the box again it is only necessary to continue the motion of the Windlass in the original direction.

In fig. 2, B are hangers, which connect the top cross-- 1. The chain 1), when held by the .side of and beneath ,the clutch-wheel d by means of the spoon h and lever k, substantially in the manner and for the purpose specified.

2. The'fiuger l, in combination with the grooved clutch-wheel (l, substantially as and for the purpose described.- 1 V p 3. The follower-bar a, guides o rigidly attached to the press at their lower ends and loose at their upper ends, and convex rubbers 1', all arranged as'explained.

4. The arrangement of the Windlass s, cords t sheaves 'u w, and follower-bar a, suhstantiallyas specilied, and to the end that the follower may be drawn over the press-box by a continuation of the same motion that elevated it.
