BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 682,514, dated September 10, 1901.

Application filed March 29, 1901. Serial No. 53,554. (No model.)

To all whom Lt may concern: 7

Be it known that I, LEANDER WILSON, of Alpha, in the county of Henry and State of Illinois, have invented a new and useful Improvement in Baling-Presses, of which the following is a specification.

My invention relates to baling-presses of' that form which are arranged horizontally and are continuously operated by belt-power and in which the plungeris worked within the casing by toggle arms and gears,-the hay or other material being fed in laterally from the top in front of the plunger and packed by an oscillating board worked automatically, while separating partition-boards are intro duced behind each bale of hay, which bales are successively forced out one end of the casing between tension devices, forming a throat or passage-way. My invention is designed to provide a greater compactness, strength, durability, simplicity, and power for this class of press; and it consists in various features of improvement, which I will now proceed to describe with reference to the drawings and then point out in the claims.

Figure l is a side elevation of the press, partly broken away. Fig. 2 is a plan view of the press, partly broken away. Fig. 3 is a vertical longitudinal section. Fig. 4 is a similarview through a portion of the press, showing another position of parts. Fig. 5 is a horizontal section in about the plane indicated by line 5 5 of Fig. 1. Fig. 6 is a vertical transverse section on line 6 6 of Fig. 3. Fig. 7 is an end view from the left-hand side of Fig; 1, and Fig. 8 is a detail.

In the drawings, A A A A represent the.

four longitudinally-arranged timbers of the press, which are connected by cross-bars B B B to form the horizontal frame, which is supported upon suitable base-bars B' B The middle part of this frame is inclosed upon its two sides and the bottom to form the feed-chamber C, Fig. 3, which opens at the top in the form of a hopper, through which the hay is introduced and is packed or fedby an oscillating board 9, Fig. 1. A

plunger 4 reciprocates in one end of the feedchamber, being operated by specially ar ranged toggle arms and gears, hereinafter described, while on the left of the feed-chamber toggle=

arms

3 and 3.

the extension of the frame forms the balingchamber with tension devices, through which the bales are pushed out one after the other in a continuous fashion.

I will first describe the construction and operation of the plunger and the oscillating feed-board, referring more especially to Figs. 1, 2, 3, 4:, and 5.

D is the band-pulley, to which continuous rotation is given to drive the press. This driving-pulley is on one end of shaft D, journaled in boxes at the end of the frame, and said shaft at the other end carries a pinion D that meshes with a larger gear-wheel D on a shaft D, carrying two pinions D D". These pinions are on opposite sides of a strong metal thrust-plate 5, having flanges cm at top and bottom bolted to the ends of the timbers A and also through the metal crosspieces B. This end plate receives the end thrust of the pressing action, and on it, about the center of its inner face, are formed lugs d a, between which is j o'inted one end of the short toggle-arm 3, the other longer arm a of the toggle being jointed to the plunger 4.

The pinions D D Fig. 5, engage with the 'teeth of two main gear-wheels E E, which have long journals turning independentlyin elongated boxes in metal side plates B B. These gear-wheels E are connected by independent links 6 6 to the axial pin 1') of the Said links connect with the gear-wheels by wrist-pins 6, located a distance from the center of the wheels equalto, two-thirds the distance between the center This position and arrangement of the separate links to the joint 7 and the circumference.

of the toggle produces the effect of permit ting the toggle-arms to be lowered to a position low down between the gear-wheels, making the mechanism more compact and direct in its action and also causing the plunger to be advanced to exert the pressing strain through four-fifths of the revolution of the said wheel (shown by arrow at, Fig.3) and to withdraw the plunger by one-fifth of a revolution, (shown by arrow y, Fig. 4,) thus 11113.1(- ing a relatively slow and powerful compression and a quick backward movement of the plunger when no work is being done. This not only gives greater power, but gives a be tied. Such -other.

longer time to feed and saves time on the back stroke. It also gives a quick and positive downward movement to the packingboard, as hereinafter described. This packing-board 9 has a brace connection at the top to its shank 9. This shank 9 is connected in alinement with its operating-lever7 bya metal pin 7 and a Wooden break-pin 7 the shank of the packing-board being inserted between the two thicknesses of the operating-lever. This produces an important result, for there is considerable strain on the packing-board, and if the hay is caked or tough the connections of the board are liable to break, as the momentum of the machine cannot be arrested, and if this breaking strain comes it merely breaks the pin 7 without doing harm to the other parts. To prevent the packingboard from dropping down from gravity in front of the plunger when the pin breaks, which would cause the packing-board to be mashed by the advance of the plunger, the end of the shank 9 of the packing-board is made inclined at at, so as to lock against the end of the operating-lever, forming a knuckle that bends in one direction, but not in the The lever 7 is rigidly attached to a rock-shaft 7, which is journaled in hearings on the top of the frame, and the lower end of said lever is branched and straddles the toggle-arm 3, (see Fig. 2,) and is at its lower end connected by links 7 torthe middle togglejoint. This causes the packing-board to rise and fall into the hopper, and its motion is differentiated like that of the plunger, so as to descend into thehopper with a quick positive packing blow and to rise more slowly. This gives a better packing action and more time for the insertion of hay into the hopper. When a sufficient quantity of material has been inserted into the hopper and packed by the successive advances of the plunger to form a bale, a partition-board is to be placed behind it and the plunger, made to act thereagainst and advance the bale to a position to partition-board is shown at 16, Figs. 3 and 4. It is held in an elevated positionin front of the hopper by the devices which Iam about to describe and at the proper moment is dropped automatically. This is accomplished by a sliding shelf 12, which supports said board until the time it is desired to fall, and said shelf is then hitched to the plunger by devices under the control of the operator, and the shelf being withdrawn the partition-board falls into the press-chamber in front of the plunger. The devices for temporarily connecting this shelf to the plunger are as follows: The shelf 12 slides on guides 9, Fig. 2, on each side of the upper frame-bars, and is provided with rods g, that pass through lugs 9 coil-springs g being arranged on said rods so as to bear against the lugs g to render the shelf spring-seated, the springs holding the shelf in its forward position beneath the partition-board to support it in elevated position. Loosely connected to the shelf there is a hook h, which has an elongated slot through it which receives the cranked portion of a rock-shaft 1", bearing on its end a crank 1*, which is connected by a rod r to a hand-lever Z, fulcrumed to the frame and projecting vertically near the feedhopper. When the hand-lever is deflected, it rocks the shaft r and lowers the hook it (see dotted lines,Fig. 4) into range of engagement by the top of the plunger, so that as the latter moves back by the power of the driving mechanism the same power is made to draw back the shelf against the tension of the springs and drop the partition board. A spring 8, Fig. 1, presses against the crank 1" and holds the rock-shaft in such position as to lift the hook 7t out of range of the plunger at all times, except when at the will of the operator the lever is deflected. This auto matic means for inserting the partition-board is a feature of importance, contributing to the safety of the life and limbs of the opera .tor, which are frequently endangered in the act of inserting these partition-boards. The partition-board is held in front of the feedchamber by means of four right angular catches m, Figs. 3 and 6, two on each side, which project into the press-chamber and which yield and allow the partition-board to 7 pass them and then hold said board against returning when the plunger moves back. These catches are forced inwardly by springs m acting upon their outer arms. When the plunger passes through the feed-chamber, these catches disappear from the chamber, and when the plunger recedes the hooks reappear in the feed-chamber and retain the hay in place, so that another charge may be fed into the feed-chamber. Just above the catches and near the top of the frame and in the feed-hopper is arranged a revolving folder 13, having longitudinal vanes which turn as the hay is squeezed past the same in passing into the hopper and also out of the feed-chamber. This folder reduces the frictional drag of the hay, and it is journaled in bearings that are spring-seated and yield upwardly, asseen in Figs. 3, 4, and 6. This folder will be about one-half below the halochamber when empty. When in operation,

the plunger-head is Withdrawn and the folder will revolve and drop into position, one wing or blade acting as a retainer, while the opposite one tucksin the hay and holds it in such shape that at the return of the plunger-head it will pack the hay in front of the next charge, making each charge separate as it is forced into the bale-chamber.

I will now describe the tension devices for the bale after it has been formed by successive charges pushed out of the feed-chamber by the plunger. (See Figs. 3 and 7.) This consists of a yielding top board 15 and two side plates H H, connected to and supported by horizontal spring-shanks I I. There are four screws n n n n, two on top of the balechamber and one on each side, tapped through metal cross-pieces G G and adapted to be turned down or adjusted by a wrench applied to their squared ends. These screws bear against coil-springs o 0, seated in cups n 19, secured to the outer sides of the board 15 and plate H. These side plates H have each two parallel horizontal convex surfaces with a depression between them, which permits a bale-band to be passed around the bale, while the top board is fiat or plane. By giving these screws a turn to the right the tension is increased on all four sides of the emerging bale. Should wet or very damp material be fed into the press, the coil-springs in the cups will permit a slight yielding to let the bale pass out without readjusting the screws, while in baling dry material the tension of the spring permits of sufficient frictional resistance on the bale to get the proper number of pounds in the bale.

In pointing out the distinctive features of the pressing mechanism I wish to call attention to the separate links 6 6 for connecting the gear-wheels to the middle toggle-joint. This permits the toggle-arms to be lowered and the machine made much more compact than when the drive-wheels are connected by a rod going across from one to another and having only a single link. It also gives room for the forked lever of the packing-board to extend below the frame and be journaled directly on the frame and be connected with the toggle-joint in a more direct and compact way.

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

1. A press comprising a framework with a reciprocating plunger and a single pair of jointed toggle-arms, the outer arm being made short, an end-thrust plate jointed thereto, and the inner arm longer and jointed to the plunger, two gear wheels arranged inside the framework and on opposite sides and having on their adjacent faces wrist-pins-located at points between their center and circumferences, a separate link connecting each wristpin to the middle joint of the toggle-arm, said toggle-arms being arranged between said links substantially as described.
