Description

1 STATES 'To all whom it may concern:

Beit known that I, JosErH C. BALDWIN, of Staunton, in the county of Augusta and State of` Virginia, have invented a new and useful Improvement in'the Manner of Constructing aMachine or Press for Pressing Hay, Cotton,

and other Substances; and I do hereby declare that the following is a full and exact description thereof.

- The press,when used for the pressing of hay, cotton, or other fibrous material, is provided with a box, within which the article to be f pressed is placed in a manner similar to that adopted in other presses for a like purpose. Within this box there is a follower attached toa strong shaft or piston-rod, upon which the power is to be exerted by which the press 'ure is effected. The power applied is communicated to the shaft or piston-rod through the intermedium of progressive levers of that kind usually known under the name of the f togglejoint.

In the accompanying drawings, Figure 1 gives a perspective view of the press, and Fig.

A2 is alongitudinal section of it through the middle of the progressive levers.

In these figures the press is represented as placed horizontally, which is the position in which it will be most conveniently used for many purposes. It may, however,if preferred, -be placed vertically. In the two figures like parts are represented by the same letters of reference.

a aa a are longitudinal pieces of timber, which constitute the four corners of the frame which incloses the box to contain the material tobe ressed. These longitudinal pieces are c'onvnected together by transverse pieces strongly framed into them, as at b c l. I

In Fig. 1, drepresents a door on the upper side of the box, hinged or turning on jointpins, f being a button or cleat to fasten it securely by meansy of gains g. There may be doors on other sides, as that at d', which is 'shown as hinged at h, and secured by a bar or Mlatch at t j k. These, however, maybe varied @in numerous ways, and do not constitute any part of my invention.

k k k represent the plank which forms the casing or sides of the box.

Tothe frame already described there is attached at one of its ends a second fram'e, con- PATENT OFFICE.

sisting in part of fou r longitudinal pieces, m m, which should equal or exceed in length those of the first frame. These are shown in the drawings as firmly attached and bolted to the transverse pieces l Zand into an end or Vcap piece, p.

The arms of the progressive levers q q are to be'received and operate between the pieces m m on two opposite sides of theframe, and within this frame also the shaft or piston-rod y yof the follower is to pass. The bolts or joint-pins r r `pass through one end of the levers q g ends d dief the levers q q, which,with the levers q q', forml the progressive levers, are brought to an edge, and are strongly armed with iron, to enable them to act upon the shaft y y. The shaft is notched across two of its opposite sides, as at z a, to receive the ends d d of the levers, which are kept up against the shaft by the action of springs a a,or oth` 'erwise By the successive moving of the arms Aof the respective progressive levers q q', so vas alternately to forman elbow and a straight line, they will be made to act upon the shaft y y and to force in the follower x. This mo-` tion I apply by means of a pinion, o, and a segment-rack, w w, the curvature vof which correspondsto that formed by the motion of the levers q q. The pinion o is attached to a shaft, o, which turns in blockst t, aiixed to the fra'me, and the ends of the segment-rack ww have holes in them which receive the bolts or joint-pins .s s, by which the respectivearms of each of the progressive levers q q are connected or hinged and upon which they work. Upon a projecting end of the shaft ois placed a lever, c c', by the vibrating of which the pinion e will be made to operate upon the segment-rack w w, and the progressive levers will consequently alternately force the shaft y and the follower forward. l

b b represent a windlass and rope, .which may, if desired, be used to draw the follower back when the operation of pressing has been completed; but I have not found it necessary in practice to'adopt any device of this kind, as it may be readily drawn back by hand. The end d d of the progressive levers may be relieved from their action on the shaft y. by taking off the pressure of the springs a a'.

Having thus fully described the construcq and through the pieces mem. The

tion of my press and shownv the manner in which the same operates, I do hereby declare that what I claim therein asconstituting my invention, and desire to secure by Letters Patent, is-

The combining of the pinion and segmentrack with the progressive levers or togglejoint, so as to cause said levers to operate up- Y on the shaft and follower, substantially in the manner herein set forth.

I do not claim either of the other parts described by me, they having been before used in other presses for a similar purpose.
