BALING=PRESS.

SPECIFICATION forming part of Letters Patent No. 392,785, dated November 13, 1888.

Application filed April 4, 1888. Serial No. 269,562. (No model.)

To all whom it may concern:

Be it known that I, lo'rrvnnr Inon GREws, of Meridian, in the county of Lauderdale and State of Mississippi, have invented a new and Improved Baling-Press, of which the follow ing is a full, clear, and exact description.

My invention relates to presses for baling cotton, hay, straw, or other material, and has for its object to provide a simple, inexpensive, easy-working, and substantial press of this character, which may be operated to form good bales with economy of time and labor.

The invention consists in certain novel features of construction and combinations of parts of thebaling-press, all as hereinafter describe and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional side elevation of my improved baling-press with the follower down. Fig. 2 is a plan view thereof with parts in horizontal section on the line as a: in Fig. 1. Fig. 3 is a sectional side elevation of the press with the follower raised. Fig. 4 is an end view of the press, taken at right angles to Fig. 3; and Fig.5 is a transverse vertical section taken on the line y yin Fig. 1.

This press is designed more particularly for pressing cotton as it comes from the gin; but it is applicable for use in baling hay, straw, or other material.

The main frame A of the press consists of suitably framed and bolted timbers having a sill or base, a, on which the follower B is sup ported when down by shoulders I) on its four upright legs,b, which next the shoulders I) are provided wit-h sharpened lower endsJf, which enter holes a in the sill, as shown in Fig. 1. of the drawings. These legs I) also form long guides to the movement of the follower up into the baling-box G, which consists of upright planks held to the main frame A, and opening at the top to the balechamber D, which comprises-a suitable top platen, E, and four vertical walls fitted to the frame to receive the bale and made adjustable in any approved way to allow removal of the bale after it is tied in the chamber. The side walls and a part of the frame or backing thereof are indicated by dotted lines in Figs. 1, 3, and 4 of the drawings. The follower and platen are provided with the usual transverse slots for admitting the ties while tying out the bales.

The lower parts of the two end walls of the baling-box (3 are formed as doors FF, each of which is made with two upright side pieces, f f, connected to upper and lower cross-pieces, ff and hung by a bar and staples, G, or other suitable hinge, to the main frame A, so as to open upward. Between the parts f f of each door is fitted a vertically-movable bar or plate, h,to which is fixed a transverselatclv bar, H, which, as the door closes downward, is adapted to engage andlock behind beveled and notched catches I, fixed to the frame A, or to the adjacent fixed portions of the balingbox walls. The latch-bar H normally rests by its gravity upon the lower cross-piece, f of the door F, and the bar or plate h of the latch extends below the door, so as to be raised to lift the latch from the catches by one of the toggle-levers which operates the follower, as presently explained.

The follower is operated by asystem of co mpound toggle-levers consisting of two long levers, J J, which are pivoted at their inner upper ends by pins or shafts j to the under side of the follower, and two opposite pairs of shorter levers, K K, each pair of which is pivoted by a pin, 75, to the sill a of the main frame, and the outer ends of each pair of levers K K are pivoted by a pinor shaft, to one of the longer levers J at some little distance from the outer ends of these levers, which are preferably forked and are provided with a shaft on which is journaled a series of pul leys or sheaves, L-three,four,or more-in the end of each lever J, three being shown in the drawings. The ends of the levers J K are preferably fitted into rounded sockets or recesses M in the follower and sill, and the levers J J and K K K K are so pivoted that their rounded ends bear on each other while they rest in the sockets M, and whereby the strain on their pivot pins or shafts is reduced to a minimum. Metal wear and anti-friction plates may be fitted at the joints between the levers and their sockets M to insure continued ease and smoothness of working and durabil ity of the entire system of toggle-leve1's,which are operated by a wire rope and drum, forming a powerful Windlass, and as neXt described.

The Windlass-rope N, which is preferably made'of wire, is fastened at h at one end to one of the long toggle-levers J, and thence the rope is passed across to the other lever and around one of its pulleys or sheaves I1, and thence back and around one of the pulleys L of the first-named toggle-lever, and thence backward and forward to and around successive pulleys L for the entire series of pulleys in both the levers J J, and from the last pulley of the series the rope is passed to the Windlass-drum O, which isjournalcdin substantial timbers I P, held to the press-framc A. The shaft of the drum is formed or provided with cranks It, by which to turn the windlass by hand, and the drum mayhave additional radial bars, 0, forming hand-levers to assist in turning the Windlass, and Hit is desired to operate the press by other than hand-power a pulley,S, may be fixed to the d ruin-sh a it to receive a bcl t from any convenient motor.

The operation of the baling'press is very simple and effective and as follows: \Vhen the follower B is down, as shown in Fig. 1 of the drawings, its legs I) rest on the frame-sill a to relieve the toggle-levers of the weight of the cotton or other material thrown into the baling-box O to be pressed, and the doors F of the box will be closed and held shut by the latches II engaging the catches I. \Vhen sufficient material for a bale has been put into the baling-box, the windlassdrum 0 will be turned to wind the rope N on it, and this will raise the toggle-levers to lift the follower, somewhat quickly at first, but with a gradually-decreasing speed of travel as the pressing of the bale between the follower and platen progresses, thus applying the increasing power of the compound levers to meet the increasing resistance to compression of the cotton or other material. As the levers J rise toward the latch-bars h, and just after the platen has moved above the end doors F, the latches II will be lifted from the catches I by the contact of the levers J with the latch-bars, which releases the doors F and allows the levers J to swing the doors open upward on their hinges to give room for these levers to enter the baling-box to carry the plunger upward to the extreme of its effective stroke to complete the pressing of the halo, which will then be tied and discharged,

and the windlassrope N will then be slacked L off to allow the follower B to fall by its gravity, and as the follower-levers J pass below the doors F or their latch-bars h these doors close and are again latched at II I about as the follower comes to a rest by its legs b on the framesill a, and all is now ready for refilling the baling-box and turning the Windlass-drum for pressing the next bale in a manner above de scribed.

The upper platen, E, is preferably made removable to allow the baling-box to be filled with material to be pressed from the top of the bale-chamber; but said platen may be fixed to the press-frame, if desired, and the material to be baled will then be fed into the balingboX below the platen, as will readily be nu dcrstood.

Having thus described my in.vention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a baling-press, of a frame, a baling-box and chamber provided with a follower, toggle-levers pivoted to the follower and the press-frame, said balingchambe]: formed at one end with hinged doors,

latches on the doors, and catches on the frame adapted to hold said doors closed and to be tripped by the toggle-levers to allow the doors to open to admit the levers into the balingchamber during the effective stroke of the follower, substantially as herein set forth.

2. The combination, in a baling-press, of a baling-box, a follower therein, toggle-levers, and connected mechanism for operating the follower, said baling-box provided with hinged doors F and sliding latches h thereon, and catches I on the press-fran'ie, substantially as herein set forth.

POTIVENT INGE GREWS.
