BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 443,172, dated December 23, 1890.

Application filed March 28, 1890. Serial No. 345,749. (No model.)

To all whom it may concern.-

leit known that I, GEORGE BEAMON ALLEN, a citizen of the United States, residing at San Leandro, Alameda county, State of Oalifornia, have invented an Improvement in llaling-Presses; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to'baling-presses; and it consists in the novel constructions, combinations, and arrangements hereinafter fully described, and specifically pointed out in the claims.

The object of my invention is to provide a simple and effective means for operating the followers of the press, for providing for the relief of the power-lever when the pressure on the follower is withdrawn, and for automatically locking and releasing the feeddoors of the press.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a side elevation of my press. Fig. 2 is a horizontal section of the frame to show the gears and operating-links in plan. Fig. 3 is a top view of the latch mechanism. Fig. 4 is a view of the operating-lever E, shown as having started on its movement to the right, as indicated-by the arrow.

A'is the body of the press, having within it a baling-chamber at each end, provided with suitable discharge-doors a. In these balingchambers are the oppositely-reciprocatin g followers B.

About the center of the press are mounted the powengears, (represented generally by C.) These are here shown as being semicircular gears interineshing horizontally in pairs. They are all mounted in horizontal planes, and there are four of them, two being mounted upon a vertical shaft 0 and the other two being mounted on a vertical shaft 0'. The pair of gearsin the same horizontal plane internicsh, as shown. One of the followerssay, for example, the one on the right-hand side is connected by a link D with the upper gear of one vertical pair and by a link D with the lower gear of the other vertical pair. The other follower--namely, the one on the lefthand side-is connected by a link D with the lower gear of the first vertical pair and by a link D with the upper gear of the other vertical pair. These connections are made by the pins d and (Z' in the rims of the gears, the former pins representing those of the links D and D and the latter pins representing those of the links D and D All. these links are branched or double, so as to fit both above and below the gear-rims. Now it will be seen that by the movement of these gears in one direction the follower on one side is driven outwardly, while the follower on the other side is withdrawn toward the center, and by the movement of the gears in the reverse direction the reverse operation takes place, the first follower being withdrawn and the second driven outwardly.

The first point of advantage to be noticed is that by connecting the followers in such a manner as to have the power imparted to them from each side equally said followers are driven straight and accurately, avoiding any undue friction in the baling'chanibers. The object in having four of these gears is to allow the several links to pass each other in accomplishing the full movement of the followers. There is a point of novelty to be noticed of great importance in the relative positions of the pins d and d, by which the power-links are connected with the gears. The pins of the links of both followers are placed to one side of the center planes of the gears. The pins dare on one side and the pins (1 are on the other side, their distance from the center planes being equal, and on account of the position and direction of movement of the gears the pins d are placed on the gears nearer their inner ends, while the pins d are placed toward their outer ends. struction provides for a much greater stroke of the followers than if said connections were placed directly in the center planes, and also provides for the immediate start of one follower on its outward stroke before the other follower is perceptibly affected to begin its return movement.

The gears are operated by the following mechanism: A power-lever E has its inner end pivoted upon one of the vertical shafts of the gears, here shown as being applied to the shaft 0. A link F has one end branched or forked and is connected with one end of the upper gear on shaft 0, and a second link F,lying directly under the first, is similarly This conconnected with the corresponding end of the lower gear. The rear ends of these links extend to one side of the lever E, and asinglepinfpasses through said ends, said pin being mounted and adapted to slide back and forth in an elongated guide slot or opening a in the lever. A third link F is similarly connected with the other end of the upper gear, and a fourth link F is similarly connected with the corresponding end of the lower gear. The other ends of these links extend to the lever E and receivea single pin f, which is mounted and adapted to slide in a longitudinal .slot or guide opening c in said lever. Pivoted near the inner end of the lever by a eross-head g is a pawl or catch-bar G, the outer end of which is adapted to bear behind the pinf of the links F and F, and said pawl has a shoulder g, which is adapted to bear behind the pin f of the links F and F when said pawl is swung over. A spring II is connected to a fixed bearing at one end and has its other end connected with the pawl or catchbar, and thetendency of saidspring is to keep the pawl or catch-bar over to its engagement normally against the pin f. The pawl or catch-bar is swung over to the other side by means of wires or rods I, connected with the ends of its cross-head g, said wires or rods extending forwardly along the lever E and connected at their forward ends with the arms of a pivoted bell-crank or elbow lever J, whereby they are adapted to be moved in opposite direction.

The operation of this mechanism is as follows: In Fig. 2 the lever E is shown as having just completed its movement to the left. Now to begin its movement to the right the pivoted bell-crank or elbow J at the outer end of lever E is turned so as to pull upon that rod I, which is farthest from the press. This will turn the pivoted cross-head g of catchbar' G, and will thereby swing said catch-bar over from its position shown in Fig. 2 to the position shown in Fig. lthat is to say, its extreme end is thereby removed from contact with pin f and its shoulder g is thrown in behind pin f, and this movement is against the tendency of spring II, which, as before stated, acts to hold the catch-bar in the position shown in Fig. 2. Now the lever E is moved on its stroke to the right, as indicated in Fig. 4. In this movement the tendency of pin f is to slide along toward the pivoted end of lever E' that is, inwardlyand the tendency of pin f is to slide outwardly along the lever. This tendency of pin f is unchecked; but the tendency off is checked by its contact with shoulder g of catclrbar G. Therefore the links F F are thereby con nected with the lever, and said links, being now pulled upon, turn the gears to the left. The links F F being free, their pin f, which at first moves outwardly freely, stops when the arrest of pin f takes place. The parts thus remain in the position of Fig. 4 through-v out the whole stroke of lever E to the right.

When the limit of this stroke is reached and the power on the lever relieved, the slight expansion of the bale would have a tendency, by throwing the follower back slightly, to turn back the gears slightly, and thereby suddenly jar or vibrate the lever; but thisbaok movement of the gears does not soaffect the lever, for the pin f of links F and F can move freely outwardly away from the catch-bars shoulder g, and the pin fof links F F is not limited at all and can play freely inwardly. To effect the return-stroke of lever E over to the left, the bell-crank J is released, and the spring H throws the catch-bar G over again, so that its shoulder g is removed from pin f and its end is thrown behind pinf. Then the movement begins. and when the now-inwardly-sliding pin f comes against the end of the bar Git is stopped, and thereby the links F and F are connected with the lever E and the gears are turned to the right, the pin f being now free. The parts remain in this position, as is shown in Fig. 2, until the stroke to the left is completed. The gears O are loose on their shafts, and by reason of the opposite connections of the powerlinks of the followers one horizontal pair of said gears has always a strain upon it; but the other horizontal pair, being independent on the shafts, can adjust themselves so as to avoid any lost motion in the mesh. In the top of the press are the upwardlyswinging feed-doors K. These are automatically raised by means of a crank-weight iv,

a rock-shaft w, carrying a lever w, and a connecting-link 10 between said lever and the doors. The doors are held down by means of sliding latches L, the ends of which project over the free edges of said doors, and said latches are normally held in a projected position by means of springs Z. These latches are alternately withdrawn in order to relieve the doors by the following means: Upon the top of a guide-frame b of each follower is a contact-bar Z). Pivoted in the top of the press at the point on is a swinging lever M, the lower end of which is adapted to be struck alternately by the contact-bars b of the follower-frames. Over the upper end of this lever is freely looped an open link N, which extends in one direction and is connected with one of the latches. A second open link N is freely fitted over the top of the lever, and extends in the other direction and is connected with the other latch. Now upon one of the contact-bars coming in contact with the lever said leveris moved in onev direction so that it pulls upon one of the open links, but moves freely in the other, and the one it pulls upon withdraws its latch. The same operation takes place with the other latch by contact with the other follower.

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