Specification forming part of `Letters IatcntNo.` 26,635, datedDecembcr 22.1859.

i a full, clear, and exact description thereof,

reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming a part of this specification,

in which- Figure l represents a top or plan view of the press when ready for pressing the cotton to form the bale. Fig. 2 represents a side view of the press when the parts are in a similar position, and also represents in red lines the pressing-box turned up in the proper position for receiving a fresh supply of cotton; and Fig. 3 represents a section through the pressing-bex F on line A B, Fig. 2.

A A BB representahorizontal main frame of any suitable length, supported by standards or posts B B', resting on a base, A. end of the frame a packing and pressing box, F, is hinged near its center to pieces b, as seen flaring at the bottom, as shown at F', Fig. 2,

. and in section, Fig. 3, for the purpose of facilitating the removal of the bale after it has been roped. The` box F is also provided with two doors, ff, hinged to the box, as seen at g, Figs. 1 and 2, one hinge only being `shown, the doors f f being held in place by means of spring-clamps c c, while the.cotton is being pressed. j l

G is the platen, which works in the box F, and is operated to press the cotton by the following mechanism, viz: A piston rod or beam, E, connects the platen G witha sliding crosshead, D, which is held in place by guide-pieces D as `it slides back and forth between the upper and lower timbers of the main frame, while to the rear of the cross-head D are hinged the levers H H and J J, as seen a't h. The levers H II are hinged to levers I I by links H H', as seen at t t'. The levers I I are in turn hinged at their inner ends to the inner ,ends of levers K K by joints 7c, while the levers J J are hinged by joints j to the outer ends of the levers K K, which turn on journals m m in the main frame. An upright capstan is arranged at the lever end of the press, as shown in the drawings, one of its bearings being in the base A and To one.

the other inone of .the cross-pieces C. Ropes or chains M M connect the outer endsof .lefV

vers I I with the capstan, so that as the cap-` 'stan is turned by lever L it will wind up both of the ropes or chains M Thelevers on each side of the machine are alike, only that levers H I on one side of the machine are s0 arranged as to work under lever J, while the levers H I on the other side work over lever J, and levers K K are also so arranged that e the inner end of one works over the innerend of the other. By this arrangement of the le-` vers room is economized, and the mechanism for pressing the cotton rendered quite compact, since the levers can work past each other.

The operation may be brieiiy stated thus: The pressing-box being turned up, as shown in red lines, Fig.,2, a sufficient quantity of cotton to form a bale is introduced through the open end, which is thus turned up. The box F is then turned down, sol that its'sides will rest on the cross-piece a', thus bringing the open end of the pressing-box on a line with the platen G, while the part a of the box F projects over the platen.` Power isrnowa-p` plied to the capstan, and as the chains or ropes M M are wound up the strain on the levers I I I causes the inner ends of levers K K to be forced back and their` outer ends forward, so as to force the levers J J against the piston-head to drive the platen into thepressing-box F.

The levers H H are also forced against the cross-head D, and assist imforcing the platen G forward against the cotton. AAs the cotton becomes pressed and the resistance against the platen G increases, the power of the levers also increases until j ust before the pressing is com pleted, the levers H Hand I I are almost in line, the projecting ends II of thelevers I I l then come into action to hold the levers HH in place. After the cottonhas been sufficiently pressed, the spring clamps or catches c c are thrown bac-k and the doors ff opened and the back and the rope 0, which is attached to the cross-head D, wound up, so as to `draw the platen back toa position which will admit of the box F being turned up again, as shown in red lines, Fig. 2.

If desired, the capstan N maybe used either to assist to press the cotton by means of any I mit a person to work at the eapstan with consuitable connection With the capstan L, or it may be used to draw the ropes in roping the bale, it being vprovided with a lever, N.

The advantages of the links H H are that by their use the levers H H can be folded back against the levers I I in amore compact manof the press may be of any suitable dimensions, and the height should be such as to pervenienee.

' Having described my improved cottonpress, what I claim and desire to seeure'by Letters Patent, is-

The combination of the levers H H and J J with the levers I I and K K, links H H, and projections I I, the Whole arranged and operating` substantially as and for the purposes set forth.

PAUL WILLIAMS.
