BALlNG-PRESS.

SPECIFICATION formingpart of Letters Patent No. 625,436, dated May 23, 1899.

Application filed May '7, 1897. Serial No. 635,525. (No model.)

To all whom it may concern.-

Be it known that I, PETER K. DEDERICK, of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in BalingPresses; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and to the letters of reference marked thereon.

'This'invention relates to improvements in baling-presses, the novel features being applicable mainly, though not exclusively, to baling-presses of the vertical or upright type, and more especially to the presses of this type in which the traverser or follower moves upward, condensing the material against the head or top of the press-case.

The invention has for its objects to improve the detail construction of the press, wherebyit may be handled and manipulated with greater facility, to reduce the weight and at the same time strengthen the construction of the framing and power, thereby permitting of a greater compression of the material, and to provide a double press or press for forming duplicate bales simultaneously which shall embody the desirable features mentioned.

Referring to the accompanying drawings, Figure 1 is a perspective view of a balingpress embodying my present improvements with the heads and doors on one side open. Fig. 2 is a vertical section showing parts in elevation. Fig. 3 is a perspective view, partly in section, showing the arrangement of the shippers forautomatically arrestingthe power mechanism at each extreme of its movement. Fig. 4 is a detail showing one of the reverse retainers. Fig. 5 is a similar view showing another form of reverse retainer. Fig. 6 is a similar view showing several modifications of reverse retainers.

Like letters of reference in the several figures indicate the same parts.

In carrying this invention into practice I preferably provide a framing which will support not only the power mechanism proper and press-case, but also the driving-power mechanism. Thus the only connections which have to be made are with the prime moveror engine through the medium of belts or equivalent devices. For this purpose Iprovide sills A, adapted to support the press-case B, and also extensions A, upon which the driving mechanism is mounted, as will be presently described, and adapted to be connected with the power mechanism through the end wall of the press-case in the ordinary manner. The press-case in the present instance is preferably substantially rectangular and is formed by upright planking suitably sup ported by appropriate bracing and having 011 each side near the top swinging doors or sections 0.

In the construction of press shown two bales are adapted to be formed simultaneously, the press-case for this purpose being divided transversely by a partition D, and the doors or swinging sections 0, above referred to, are preferably connected together on each side of the press-case, first, by a girder at the bottom having suitable intermediate and end bearings o and constituting the hinge or pivotal support for the doors or sections, and, secondly, by a top girder G, ex tending the entire length of the press-case and having notches or recesses c at the ends for the reception of the ends of transverse girders 0 The girders thus form a complete encircling band around the top of the press case and are held in their relative positions with the door 0 closed'by hooks or catches E, pivotally mounted on the press-case and adapted to automatically drop over and hold the longitudinal girders O, as will be readily understood from an inspection of Fig. 1.

The traverser or follower working vertically in the press-case is lettered F, Fig. 1, and it is preferably formed in the main by two rel* atively thin metallic plates f, projecting through narrow slots f in one end of the cas= ing and passing through similar slots in the central partition D. These plates support the pivotal bearings for the upper ends of the power-levers, and upon them is built the face of the follower F, which latter is usually made up of heavy wooden planks and girders or timbers bolted alongside of the plates f, be* fore referred to.

The power mechanism in the present instance (see Fig.2) consists, preferably, ofthree pairs of jointed toggles G, one of the pairs, as shown, that nearest the left-hand end,be-

ing extended in the form of a toggle-lever G and adapted for the connection of the driving mechanism at its lower end. At or near the joints of the respective toggles they are connected together by longitudinal bars or connections G whereby they are caused to move in unison and to raise and lower the traverser while maintaining it in its horizontal position. It will be particularly observed that one pair of toggles is located in each of the press-chambers and the other pair of tog? gles is located entirely outside of the presscasing. Thus there is no necessity for cutting away the sides of the press-case for the passage of the knuckles. The lower togglearms of the pairs G are made double-that is to say, there is a single upper toggle-arm and two lower toggle-arms jointed together at the center-and the lower toggle-arms have their lower ends separated somewhat widely and pivotally mounted in metallic bearing blocks or boxes H, suitably secured to the frame,and also adapted to accommodate the lower ends of vertically-disposed rods extending to the top of the press-case and adapted to hold the heads against which the pressing operation is performed. In the preferred construction the lower ends of the rods are provided with eyes, through which the pins forming the pivots of the toggle-arms pass, whereby, as will be readily understood, the entire strain of the pressing operation is taken up in the powermechanism heads and connecting-rods rather than by the press-frame itself, and consequently little or no vertical framing, such as has been previously necessary in all upright presses, is now found necessary. The rods extending up from the central toggle-arms pass up in the partition D and can be seen in Fig. 1, beinglettered I, and at their upper ends they pass through a casting 1, above which they receive plates or washers t' for retaining the casting in place. Said casting, as in my application, Serial No. 621,856, constitutes the lock or retainer for the inner ends of the heads K. The heads Kare themselves mounted upon the upperends of sway bars or rods It at each end of the press, which rods k extend down and are connected to the bearings of the toggle-joints, as before explained. By mounting the heads in this manner on the upper ends of long sway-bars and providing stops, such as the cross-planking 7.2, for preventing the heads and sway-bars from assuming an angle with relation to each other less than a right angle said heads are caused when swung open, as shown in Fig. 1, to rise up away from the edges of the press-case and when swung back to move down closely thereon, with their forward ends beneath the casting I, before referred to. In addition itwill be observed that the operator has little or none of the weight of the head to lift in opening or closing the press-case, as the heads swing baclgand from the very start the weight necessary to be lifted becomes less and less,

owing to the fact that the heads move farther and farther over their pivotal points.

To limit the outward swing of the heads, stops or limiting-rods K are preferably connected with the press-case at each end at a point proximately midway of its height, and at the end of the press through whichthe traverser projects the transverse girth, which must be divided for the passage of the traverser end and power mechanism, is held in place and the requisite strength afforded by a metallic connection L, Fig. 1, slotted or cut away on the inner side for the accommoda tion of the power mechanism and end of the traverser.

The sway-bars at the left-hand end of the press, Fig. I, extend down outside of the press-case as at the right-hand end; but inasmuch as the pivots for the toggle-arms at this end are located within the press-case, Fig. 2, it is necessary or desirable that the ends of the sway-bars should be pivotally connected to links or short connections extending through the wall of the press-case diagonally upward and having at their upper ends eyes or other suitable form of pivotal connection for the lower ends of the sway-bars.

In operating presses of this character it is customary to close the side doors, leaving the top or heads open, throw material into the press-case, and then tramp it down as closely as possible upon the traverser, which is then at the bottom of the press-case. The inside surface of the press-case is very smooth owing to the friction of the pressed material against it and to the fact that it is made so to prevent undue friction, and consequently it the material being baled is at all elastic the amount which can be tramped into the presscase is limited, practice demonstrating that as soon as the operator steps from one point to another the material at once returns to its normal height and no more material can be gotten into the press-case. The result is that in order to secure sizable bales the press-case must be made unduly tall, and with a View to overcoming this difficulty I now locate in the walls of the press-case what I term reverse retainers-that is to say, retainers which operate reversely to the action of the traverser. With such retainers when the materialhay,for instance-is tramped down it is retained against springing upwardly, and practice hasdemonstrated that a very much larger quantity can be tramped into the press-case in this way. \Vhen the heads are returned to place and the end of the presscase closed,these retainers may be withdrawn automatically or otherwise and the pressing operation proceeded with as ordinarily.

In Fig. 4 I have illustrated in section and diagram matically one form of reverse retainer which consists, essentially, of a series of inwardly-projecting teeth M, having their holdin g-faces set to hold the material reversely to the action of the traverser and united or formed on bars, such as m, and at the lower ends such bars are provided with inwardlyprojecting feet or extensions M. The bars in and teeth carried thereby are movable vertically to a limited extent, being supported by transverse pins 'm, working incurved or diagonally-arranged slots m in guides or castings m secured to the press-case, and consequently when moved upwardly said teeth.

are withdrawn from the inner surface of the press-case, leaving said surface practically smooth for the pressing operation. The feet or extensions M before referred to serve as a means for insuring the projecting of the teeth within the press-case when the hay is tramped therein, as the weight of the hay upon said feet or extensions will force the rods m downward. Openings may be formed in the traverser for the passage of these extensions, or, if desired, the extensions may pass under the traverser in position to be struck thereby when the traverser is in its lowermost position; but when the traverser commences to move upwardly this pressure is relieved, and the first movement of the hay upwardly causes the teeth to automatically withdraw, as before explained.

lVhere the reverse retainers are located in the sides of the press-case, they should also extend through the doors O, and for this purpose they are centrally divided and the two sections united by a strip or other flexible connection m", which will permit the doors to swing open, as will be readily understood.

If desired, the reverse retainers may be mounted upon a support by short pivoted links 0, Fig. 5, and to secure the necessary movement of the retainers they may be connected at their lower end with a lever O, pivoted to the frame and constituting one of the links and having its forward end 0 extended beneath the hay or, preferably, as shown, beneath the traverser itself, While to secure a positive upward movement or release of the retainers the lever may be provided with a shorter extension 0 adapted to rest above the traverser when the latter is in its lowermost position, as shown in this figure, and adapted when the traverser moves upward to be struck thereby and turned to the position indicatedin dotted lines. It is retained in this position by friction or by a spring 0 until the traverser again descends and turns it down to the position shown in full lines.

Obviously many difierent forms of retainers may be employed to accomplish the result aimed at, it only being necessary that they should operate reversely to the action of the traverser, and I have shown in Fig. 6 an upright or side of a press-case having three different forms of retainers thereon, that at the top consisting of a spring-pressed pivoted segment P, held in place by a spring 1) and adapted to be normally projected within the casing thereby, so as to yield under excessive pressure, as when the traverser is traveling upwardly, but of sufficient strength to retain the hay againstthe traverser when tramped naled in an arm or link Q pivoted at a point outside of the press-case to a bracket or other suitable support Q and held against rotation in one direction by a pawl Q for retaining the hay when tramped. The link or arm Q is held down by a spring Q but will yield upwardly as the traverser rises, the strength of the spring Q being sufiicient, however, to retain the hay, as before explained.

Obviously retainers may be located in the side Walls of the press-case Wherever found necessary or desirable to hold the hay down while being tramped, and hence I do not wish to be limited either to the specific form of the retainers or to the particular location thereof.

By reference to Fig. 2 it will be seen that the driving mechanism consists of a drum R, journaled in the frame or sills and having a doubled chain or flexible connection extend-- ing loosely through a hole 9 in the lowerend of the extended toggle-lever G to render and equalize in winding, so as to draw said lever outwardly and raise the platen when the chain or flexible connection is Wound on the drum. For convenience and to hold the chain in its proper position or in line with the lower end of the lever it is preferably passed around a roller R, journaled in the sill-framing, with its lower side or periphery approximately on a level with the lower end of the lever. The drum is provided at one end with a wormwheel R with which a worm R meshes, the latter being mounted on a shaft extending longitudinally of the frame and carrying three pulleys S S S the central pulley S being fast on the shaft,'whi1e the two outside pulleys S and S are loose and adapted to receive driving-belts running in opposite directions or one straight and the other crossed. When the belt is shifted to the central pulley, the

traverser will be moved upwardly, and when the opposite belt is shifted to the central pulley the traverser will be moved in the opposite direction, and in order to secure an automatic stoppage of the traverser in each direction when the traverser is moved to the limit of its stroke in either direction advantage is taken of the movement of the togglelever to move belt-shifters, which will move the belts to the loose pulleys.

Referring to Fig. 3, it will be seen that I provide two belt-shifters, (lettered T and R which belt-shifters are connected at their ends to hand-levers T and R pivoted, respectively, to the sills or framing of the press at any suitable points. From these hand-levers T and R rods T and R extend to oppositely-arranged pivoted levers T and R The lever T is in position to be struck and moved by the power mechanism or toggle-lever when at the lower extreme of its movement and the lever R is in position to be struck and moved by said power-lever when at the upward extreme of its movement. Such movements of the levers T and B will cause the shifting of the belt to the loose pulleys, thereby stopping the operation of the power mechanism until it is again put in motion by moving the hand-levers T or R Having thus described my invention, what I claim as new is 1. In a baling-press the combination with the press-case having a vertical partition clividing it into independent bale-chambers, a traverser located in said press-case and three toggles located respectively adjacent the end walls of the press-case, and central partition for advancing the traverser, of a central pair of bars extending from the pivotal bearings of the central toggle to the upper end of the partition and lying within the partition, pairs of bars pivotally connectedwith the bearings of the toggles at each end of the press, heads supported on the upper ends of said last-mentioned bars and cooperating with and supported by the centrally-arranged bars when in pressing position; substantially as described.
