-'4.0M V Y IMPROVEMENT IN' HAY AND COTTON-PRESSES. l

The Schedule referred to in these Letters Patent and making part of the name.

To allwhom it may concern:

Beit known that I, WILLIAM G. Banks, of Como Depot, in the county of Panola, and State of Mississippi, have invented a new and improved Cotton and Hay-Press and I do hereby declare that the followingis a full, clear, and exact description of the construction and operation of the same, reference being had to tlccbmpanyin g drawings, making a part of this specification, in which- 1 Figure 1 is a side view, showing la portion inA section.

Figure 2 is a side view. v

lhis invention relates to that form of press patented by W. C. Banks, June 1'8, l1867, No. 155,865, the es-I sential principle of which is, that the block that supports the screw is capable of being moved aside when the platen is raised, so as to leave the top of the press- ,box unobstructed. f

This invention relates to an improved arrangement for operating the movable supporting-block referred to.

' In the drawings- A represents the four corner-posts of the frame;

B B, the cross-beams uniting'said posts;

O, the press-box, in which the bale is formed c c, the hinged sides ofthe press-box, held together by rods a a, made thin and at, and provided with ay head at each end, the flat thin Ablade sinking into an open slot in the edge of the doors c c, and' the heads coming against their outer faces, so' as to prevent them from opening. y y

D, the conducting-tube above the press-box, through which the platen passes, up and down;

E, a screw-rod, rigidly fixed to the platen, so as not y to 'be capable of turning;

F, a rotating screw-uut, surrounding a portion of the screw-rod, and, by its rotations, moving the rod up or down; f

G, the supporting-beam, hereinbefore referred to, which sustains the screw-nut F, and furnishes it a bearing;

H, a beam, attached to the screw-nut, for the purpose of affording means to turn'itin its bearings;

their upper ends, directlyl over the screw-rods, where 'a hole is provided, to allowfit to rise through them, and attached to theouter ends of beam H, at h h;

K, the awning or canopy, supported on a'frame attaohed to sweeps I J and beam H; and

L L L L, four levers, pivoted to the posts A A, at l l, and connected to the ends of beam G by means of chains g g, by which the beam G can he` slid from one I J, two inclined sweeps, connected together at;

l side'to the other, so as to bring the .platen to any del sred position. i

When not in use, the levers hangv vertically, as

bering the instrument, either in appearance, or, in fact. The construction of the screw-nut F and its bearings is as follows: A groove, m, is cut around the nut, at the point that is to come at the upper edge of the'supportingbeam, and a flange or collar, or., is formed near the lower end of the nut, its under side coming in the same plane with the under surface of the beam.

A gain, o','is cnt vin the-under side of the beam, around the hole occupied by the nut and screw-rod.

4Into this gai na metallic plate, Rfis inserted, having ridges 'fr rat its ends, slightly thicker than the ange n.A f vThe' plate E is slipped down over the screw-nut till seen in fig. 1.

The eridof the nut below-the collar now projects downa short distance, and another plate, S, is slipped over it, and brought up against the ridges fr Jr, where itfis' fastened by screw-bolts, so that the collar or flange is confined between the two plates 1tl S, free to turn, but incapable of rising or falling. This secures the nut in place, and 'enables it to operate the screw-rod after the latter has. been inserted, in the manner and for the purposes above indicated. 1 In order, however, to hold the nut still more firmly, and to afford myself the means of adjusting its bearthe upper surface of the beam G, designated, respectively, 'w w', each being fastened with screws, and the, two capable of being Ldjusted toward or from each other, at pleasure, by moving the screws.

The adjacent edges oi' these two plates are cut away, so as to fit to the-sides of the nut within the shown, being entirely out of the way, and not encunrit rests on the collar, and is then raised, by means of y the nut, until it reaches its position in the gain, as

ings as it wears away, I employ two other plates on plicated apparatus heretofore employed, is well illus- A.trated by comparing the upper bearing, composed of the two small half plates w w, with the lower bearing, composed of the two large plates R S, the collar between them, and the gain o, in which they operate, itself one of the simplest bearings heretofore made for a similar purpose.

The advantagein point; of simplicity, cheapness, lightness, and adjustability, is, obviously, with the upper bearing. y

Having thus described my invention,

What I claim as new, and desire to secure by Let;-

ters Patent, is-

The `arrangement; of the four levers L L L L, two at each end of the beam G, pivoted, at theinupper end, to the frame of the press, and connected, by chains g g, or equivalent device, to the ends of said beam, substantially as and for the purposes specied. d
