Letters Patent N o. 100,105, dated February 22, 1870.

IMPROVEMENT IN 'COTTON-PRESSES.

The Schedule referred to in theseLetters Patent and making part of the same.

To all whom it may concern Beit known that I, CHARLES J. BnAsLnY, of Petersburg, in the county of Dinwiddie, and State of Virginia, have invented a new and useful Improvement in Presses; and I do hereby declare that the 4following is a full, clear, and exact description thereoi* the pawls may also be caused to act as a brake on the ratchet-wheel, to retardy the fall ofl the follower.

TheI invention also comprises an arrangement of the support .for the journals of the winding-drums, in

connection with the beam against which the force of the follower inY pressing is delivered, whereby the resistance of the follower is sustained mainlybythe said beam, all as hereinafter more fully speced.

Figure 1 is a side elevation of apress provided with .my improvements, and

. Figure 2 is an elevation taken at right angles to the'plane of iig. 1.

Similar letters of reference indicate corresponding parts.

A is the case;

B, the follower;

' O, the chains;

.1),- the winding-barrels or drums;

E, 'the ratchet-wheels ;l

F, the retaining-pawls;

G, the operating-pawls; and

H, the pawl-levers.

The retaining-pawls -are arranged on pivots above the ratchet-Wheels, so that their free ends fall down upon the front faces of the ratchets, and engage the teeth thereof. l l

The pawls G .are pivoted to the paWl-levers a short distance in front ofthe said Aratchets, and have pendent curved arms, G1, which, when the levers are raised, cause the points I td engage the teeth of the ratchets, and, when the said'levers are swung down low enough,strike against the caseor blocks K placed thereon, and cause the points I to be disengaged from t he ratchet-teeth.

The. short ends-L of these levers are extended beyond the pivots, and so shaped that, when the paw'ls G are thus brought down upon the case anddisenv` gaged, they` will bear under the free ends of lthe retaining-pawls, anddisengage them also, leaving the drums free to be unwound by the weight of the follower or other means.

The pawls G are `also provided with projections, G2,- on the sides ofthe pivots oppsite the points I, which, at the time the levers are thus depressed, will be forced, by the arms GrI bearin g on the blocks K, against the points of the teeth of the ratchet-wheels, and act thereon as brakes, to govern the fall of thefollowers,

Thus, by this simple arrangement, the bami-levers H .may be used to raise. the follower,l detach .the pawls, to let'it fall, and to apply the brakes to contini' the fall, and this, too, by o'nly'moving them in one di-v rection in a greaterjdegree than is required to raise the followers, and holding them a short time.

The journals of the barrels are arranged, in boxes M, attached to vertical bars on the side. of the frame. They also pass through links N, suspended frombolts O, supported in suitable lugs I at the top of thcv frame.

The yokesy Q'are also attached to the bolts O, and swing over the ends of the beam It at the top of the case. 'Y

'Ihe force of the follower in pressing is delivered against this top, and is sustained by the beam It, which, being connected in thisway to the journals of the barrel, affords a means of' 'relieving the bearings of the drum and other parts of the machine fromthe action of the said force.

This arrangement of the' patri-levers', pawls, and

ratchetwheels is applicable to all apparatus of like character 'for raising heavy weights, and I do not limit myself to the application to presses only.

Having-thus described my invention, y l

I claim as new and desire to secure by Letters Patent- 1. The combination of the hand-lever H, having projection L thereon, with' the pawl G G? I, block K, and detent F, to operate the ratchet-wheel and shaft,

'in lthe manner and for the purpose set fort-h.

2. The arrangement with the drum-shaftv and the beam R of the links N, bolts Q, and yokes Q, all sub-- stautially as specified.
