UNITED STATES PATENT OEEICE.

SETH LAMB, OF NEV YORK, N. Y.

` IMPROVEMENT 1N COTTON-PRESSES.

Specification forming part of Letters Patent No. 3,489, dated March 16, 1844.

j 1ro all whom it may concern:

all the other parts of the machine remaining the same as described in my patent granted the 12th of May, 1843. i

To the foot-block b two braces or tailipieces,

b2, are firmly affixed which, are parallel with and rest upon the two side pieces of the frame a and projecting back of the foot-block. On the upper side of these pieces b2 are formed ratchets, into which a pawl, d?, catches. This pawl is formed of across-piece,that takesinto the ratchet, and two connectingbars, that ex tend down one on each side of the side-piece, a', and have a pin pass through them, securing themto said piece a, so as to allow them to swivel. These hold the foot-block in any required place within the compass of the ratchet. Ashaft, c2, is put through both side pieces of the frame horizontally underneath the foot-block braces,and has a bearing in each side piece, out of which a mortise is cut from the upper side large enough to receive cogwheels h2, that move the shaft near each end and about in the center of the pieces a. These work into a rack ou the under side of the braces b2, above named, and as `the shaft is turned move the foot-block back .and forth. One end of the shaft extend, out beyond the side of the press, and has on ita lever, Z', that turns independent of the shaft, and outj side of this lever a ratchet, which is fixed on the shaft, and on the lever a pawl is attached that works into the wheel, by which means the lever is made to work the shaft. The operation of this is to take up the slack when the bale is put in before beginning to bring down thefollower.

Another' modification is shown in Fig. 5, in which7 instead of the above apparatus, two segments of wheels, x, are hung on the shaft c2. Inside the frame, on each side from the upper side of this segment of semi -/wheels, a short bar connects it with the foot-block b, the bar being jointed at each end. From the lower side of the segment a projecting arm, y, is

jointed the other end vof which extends forward under the two blocks of the press, and is connected to the lever e by a shacklebar, y', about one-third of the length of lever z from the follower c, and is stayed by a stay-` .supports the bed in its proper level till the loop z reaches the jog, when that end of the bed descends and leaves the bale free. On the follower c receding the bed is again raised.

VhatI claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the pawl and racks with the foot-block of a press constructed and arranged in the manner and for the purpose herein set forth. v Y

2. In combination with the movable footblock, the segment fr, and lever y, by which it isconnected with the main levers g, in the manner described.

3. The employment of the falling bed z, on which the bale rests, constructed and arranged as before specied, so that it shall remain in its position till the bale is pressed, when it falls out of the way till the bale is tied and the levers connected with the head-block start- SETH LAMB.
