JOHN MARCH, OF EDEN, NEW YORK.

HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 269,303,6lated December 19, 1882,

Application filed April 15, 1882. (No model.)

To all whom it may concern I Be it known that I, JOHN MARCH, a citizen of the United States, residing in Eden, in the.

ing a toggle-joint mechanism with the ropes and pulleys, all ofwhich will be fully and clearly hereinafter shown and described by reference to the accompanying drawings, in which Figure 1 is a perspective view of the machine complete, except the capstan and its connections. Fig. 2 is a side elevation of the capstan and its releasing mechanism. Fig. 3, Sheet 2, is a top View of the capstan-releasing device; and Fig. 4- represents a top view of as much of the hay-press as is necessary to show the mechanism for enlarging or contracting the pressing-chamber.

Arepresents the case or body of the machine; B,the doors of the pressing-chamber, of which there are two, provided with the usual fastening devices, a a

The pressing-platen G, which is arranged to move vertically inside of the machine, and the sliding cover on top, are madein the usual way, or similar to the same parts described in my PatentNo. 244,27 3, so that a further description of them here is unnecessary. The pressingplaten G is provided with the usual projecting parts, 0, which project through a slot or opening, D, on each side of the machine.

E representsapulley,of which there are twoone on each side of the machinefirn1lysecured by an iron strap, 0 to the parts 0.

F represents a rope (or cable or chain) fastened to the lever F by bolts or other wellknown means, f there being two levers F-- one on each side of the machine jointed to the base by bolts 9. Each lever F is provided with a lever, G, jointed thereto by bolts 9, and to the parts 0' of the pressing-platen by bolts 9 The rope F passes from each lever F to and under a pulley, G, and then up in the direction of the arrow e, over the pulleys G and down in the direction of the arrow c, under the pulleys E, then up in the direction of the arrow e over the pulley G and down in the direction of the arrow 0 under the pulleys G, and from thence in the direction of the arrows e to the capstan H, to which it is connected in the usual way.

The operation of this part of the invention will be understood from the drawings. (See Fig. 1.) When the capstan is turned so that the ropes move in the direction of the arrows the pressing-platen is moved up by the combined action of the ropes and pulleys and the toggle-joints F G, which increase the power of the machine as the pressing-platen is moved up.

The mechanism for enlarging the pressingchamber after the bale has been compressed, or as soon as the door is opened, so as to allow the bale to be easily removed, is shown in Fig.4.

B B represent the doors-one on each side of the machine-andconnected to itin theusual way by hinges. ()n the inside of the pressingchamber is a swinging plate or side piece, J, hinged or jointed in any well-known way to one side of the pressing-chamber by a bolt or other'device, I, so that its opposite side can swing slightly to or from the side, as shown. One edge of the door B is provided with a rib, J, which, as will be seen, (when shut,) holds the side piece, J, so as to contract the size of the pressing-chamber,and when the door is opened, as shown by the dotted lines B it allows it to swing back, and thereby enlarge the said chamber, so that the compressed bale can be easily withdrawn.

The capstan and its locking and unlocking mechanism are shown in Figs. 2and 3, in which E represents the capstan made in the usual way. It is strongly secured in the frame-work J J K K. To the upper part of the capstan is rigidly secured a horizontal cross-piece, L, and the pole and block L L is bolted thereto by a bolt, m, so it can turn easily on the capstan, and also a hand-lever, N.

N N represent two yokes jointed by bolts 0 to the pole L. The lower parts of the yokes are constructed so that when the device is locked they fit over the ends of the cross-piece L, as shown, and when unlocked they move off and releaseit,as shown by the dotted lines. The

Ice

yokes are connected by rods or arms 0 O to the arm or lever N in any well-known way, so as to be operated by it.

The object of the locking and unlocking device is to allow the motion of the capstan to be reversed, so that the pressing-platen may be moved down without causing the horse (which may be connected to the pole L for opcrating it) to move backward.

I lay no claim here to the capstan, as Imay make it the subject of a separate application.

I claim as my invention 1. In a hay-press, the levers or arms F, their lower ends being jointed to the base of the machine by bolts g, so as to act as levers, and the arms G, jointed thereto by bolts g at their lower ends, and havingtheir upper endsjointed by bolts 9 to the under sides of the platen O, the ropes or cables F being connected to the lever F by bolts f so as to pass underthe pulleys G on each end of the platen O, in combination with the running pulley E, standing pulleys G2 G G, and a suitable capstan, substantially as and for the purposes specified.

2. In a hay-press, the door B, provided with the rib J, in combination with the swinging or hinged plate or side piece, J, arranged within the compressing-chamber, substantially as and for the purposes specified.

JOHN MARCH.
