CYRUS J. FAY, OF NORTH LINCOLN, MAINE.

IMPROIVEM ENT IN COTTON-PRESSES.

Specilication forming part of Letters Patent No. 10,472, dated January 31, 1854.

i'o all whom it may concern: I

Be it known that I, CRYUs J. FAY, of North y Lincoln, in the county of Penobscot and State of Maine, have invented sundry new and useful Improvements in Hay, Cider, and lCotton Presses; and I hereby declare the following to be a full, clear, and exact description -of the same, reference being had to the annexed drawings, making part of this specification.

Figure l is an isometrical view of the press;`

apart to allow the straps or ropes with which the material was to be secured to be passed through the spaces between them, the upper plank, which was placed longitudinally, being secured firmly to them for the purpose' of maintaining them in their places; otherwise they would be liable to be forced together as they descended, and there would be no space left between them through which to pass the straps. To obviate this difficulty, and to enable me to use separate planks of small size without thedanger of their crowding together, is the object of my improvement. This I accomplish by placing guides upon the interior of the box of the press, between which guides the follower-planks descend, the guides keeping them constantly the required distance apart. y

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

B is the frame-work of the press; C, the interior boxing of the same.

D are the doors, which are closed while the material is being pressed and opened when it is to be taken from the press. c

E are the vertical cleats upon the inside of the press, between which are placed the sections F of the follower. These sections are v thus kept separate by the cleats E, and the spaces between them necessary for thepassage of the straps which are to eonne the bale are preserved. This sectional follower may be easily managed by a boy. If, however, the sections were all secured together by an additional plank, the weight would be so great that the strength of two men would be re-v quired to manage it.

Upon the top of the follower rests the pressbeam G, over the ends of which pass the chains H, which are/secured to the shaft I, upon one end of which are secured two ratchet-wheels,v a and a. Upon the latter rests the retainingpawl b, and by means of the former the shaft I is made to revolve in the following manner:

L is a lever, upon the end of which are two side plates, c o, of the form represented in Figs. 3 and 4.-

d is the operating-dog7 which is pivoted to the lever L at the point x. This lever is placed overthe ratchet-wheel c in such a manner that the side plates, c c', shall pass one upon each side'of the ratchetwheel, into the teeth of which the hook of the dog d engages. 'By depressing this lever the shaft I is. made to revolve in the direction 'of the arrow, the shaft being prevented from returning when the lever is againvraised by the pawl b. It is evident that by working this lever'the pressbeam is made to descend. The doors D are secured in a closed position by the upright bar M, the foot of this -bar passes into a mortise in the sill O, and the top under a catch in one of the cross-timbersof the press.

In presses of this description as heretofore constructed, when the bar which confined the doors was, removed, the latter iiew violently open, tearing off the hinges, and oftentimes injuring those standing by. To obviate this inconvenience I have hinged my doors at the points ff', and when closed they bear against each other at the point e of Fig. 2. As this point is far within the line joiningthe points f and f', it is evident that the doors will not be easily forced open. They are, therefore, held closed after the bar M is removed until they are relieved by the attendants and suffered gradually to open. Upon the ends of the cross-timbers of the doors are tenons m,

which enter mortises in the frame-work of the press, and thus the hinges are relieved from ,g

the strain which would otherwise come upon In testimony whereof I have hereunto set them. signature this 6th day of ApriLvA. D. 1853.

Having thus described my invention, what I claim as new, and desire to secure by Letters C. J. FAY. Patent', is-

The use of the slats or guide-strips E, ar- Witnesses: ranged and operating in the manner substan- JOHN S. GLOW,
