SPECIFICATION forming part of Letters Patent No. 787,501, dated April 18, 1905.'

Application filed April 27, 1903. Renewed February 20, 1905- Serial No. 246,494. v

To all whom it may concern:

Be it known that I, DONALD DONALD, a citizen of New-Zealand, residing at Masterton. New Zealand, have invented certain new and useful Improvements in Baling-Presses, of which the following is a specification.

This invention relates to improvements in baling-prcsses. and more particularly in manually-operated presses which can be made in comparatively light and portable form and are especially adapted for use on farms and at stations where the heavy powerdriven presses cannot be had.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims when considered in connection with the accompanying drawings, in which Figure 1 is a side elevation of the press as it appears when loaded ready for the compressing operation to begin. Fig. 2 is a sectional side elevation thereof. Fig. 3 is an end elevation thereof. Fig. 4 is a side elevation of the press as it appears when the upper box is swung down upon the ground. Fig. 5 is a top plan view of the press as it appears when the upper box is swung down upon the ground and the door of the lower box is opened to admit the carriage, which is here shown as occupying a position part way within the lower box. Fig. 6 is an enlarged side elevation of the jack mechanism. Fig. 7 is a sectional detail thereof,'taken on line 7 7 of Fig. 6. Fig. 8 is a perspective detail of the device for fastening the edges of the cloth within which the bale is formed. Fig. 9 is a sectional detail showing the manner in which the top plate is secured within the end of the upper box. Fig. 10 is a sectional side elevation of a carriage and bale as they appear when withdrawn from the lower box after the com pressing operation is complete. Fig. 11 is a perspective view of a modified form of press embodying my construction in parts. Fig. 12 is a side elevation of the press as it appears while being used without the boxes.

The press thus illustrated consists of two by pivotally-connected iron straps 1 and 2, so

that the top box can be swung down until it rests upon the ground opposite the lower box, as shown in Fig. 4. Said lower box is simply a four-sided inclosure open at both ends and bound around by stiffening-bands 3, preferably of angle-iron, which prevent its sides from bulging under pressure. The upper box A is of similar but somewhat lighter construction, which in its raised position fits closely upon the upper end of the box B and forms, in efifect, a continuation or extension thereof. One side 4 of the lower box A is made in the form of a door, which can be swung open to admit a carriage (l, which consists of a rectangular base-plate 5 and vertical standards 6, secured to opposite sides of its base-plate and carrying jack devices D at their upper ends. The baseplate 5 is rectangular in shape and just large enough to fit within the lower box when closed, except that it has projections 7 at the middle of two of its opposite sides, which extend out through recesses or notches 8 in the corresponding sides of the box. rolled into the box are accommodated by slots '9 in the sides of the box B and by openings 10, left between the Wide ends of tapered filling-blocks I), that are provided on these sides of the box within the angle-iron bands 3, which latter to form a sort of girder construction.

Cooperating with each of the jack devices D and forming a part thereof is a verticallymovable rack-bar 11, having upwardly-pointing teeth on its inner face, which are adapted to be engaged in alternation by loop-shaped links or pawls 12 and 13 of the jack, the ratchet-bar being drawn down through these loops as the jack is operated. This operation of the jack is accomplished in the usual manner by a lever 14, which can beswung up and down to give movement to an oscillating fulcrum 15. The links 12 and 13 are pivotally connected with this fulcrum on opposite sides of its center, as caused to alternately slide up over and pull down upon the teeth of the rack-bar, against which they are held by springs s. The pivotal point of the outer pawl 13 is preferably arranged farther from the center than that of are here bent around them so as These standards when the carriage is shown, and are thus the inner pawl 12, so that during the downward movement of the lever, when the weight of the body can be thrown upon it, the leverage is reduced and the effective movement increased, as compared with that which occurs when the lever is lifted, as it must necessarily be, by main strength.

The ratchet-bars 11 are of such length that they may be raised to full height of the top box A when the latter is superposed upon the lower box and are adapted to be detachably connected with a cap or top plate 16, which fits within the box A and forms the opposing surface of the press to the base-plate 5. As herein shown, a transverse bar 17 of this cap projects out through the sides of the box and is temporarily secured to the upper ends of the ratchet-bars 11 by loops 18, and to accommodate this bar and permit the cap to be drawn down the full depth of the box A its sides are also provided with vertical slots 9 and its angle-irons with filling-blocks 72, separated by openings 10, like the corresponding parts of the lower box B.

In the operation of the press the top box A is swung over upon its hinges until it rests upon the ground opposite the lower box B, Figs. and 5. The cap-plate 16 is then slid into the (now) lower end of the box A and allowed to rest upon cleats 19 on the inner sides of the box, which is cut out at one end of these cleats to admit of the insertion of the cap-plate in this manner, Fig-11. The carriage C, having then been pushed into the lower box A, the open side or door 4; of the latter is closed and fastened by swing-linksL or the like, and the box is then lined with a cloth or envelop E, within which the bale is to be inclosed, the cap-plate 16 being covered with a rectangular piece 6 of similar material for closing the head of the bale. Both boxes are then filled to the limit of their capacity with the material to be baled, and the top box A is swung back upon thebox B, as shown in Figs. 1 and 2 of the drawings. The cap-plate now occupies the extreme top of the upper box, and all the material to be compressed is contained within the continuous receptacle formed by the two boxes between the base-plate 5 of the press and this cap-plate 16. The ratchet-bars 11 can now be lifted and connected to the cap-plate by their links 18, and thereupon the operation of the jack devices moving their levers 14 like pumphandles will force all the material in the upper box down into the lower one. The compressing" operation is now complete,.and it only remains to sew the top piece E to the rest of the bale-cover and remove the bale from the press. To accomplish this, the top box is swung back upon the ground, the side or door 4, of the lower box is opened, and the press-carriage C withdrawn bodily, Fig. 10, together with the bale, which is still held tightly compressed between the base and top plates of the carriage. This leavesthe edges of the bale free for the sewing of the cover, after which the pressure is relieved by releasing the pawl-links of the jacks from the ratchet-bar, as may be done conveniently by means of hand-levers Z, that are pivoted to each jack-housing at its upper end, Fig. 6. The bale may then be pushed out of the carriage and thelatter moved back into the lower box ready for the operation to be repeated.

The raising and lowering of the top box A can be accomplished by main strength; but as a further improvement I have shown mechanism for aiding in the operation, consisting of a toothed rack-bar 20, which is pivoted to the upper box at 21 and intermeshes with a pinion 22 on the lower box. The shaft of this pinion is provided with a crank 23 and serves to pivotally support a triangular plate .24, in the corners of which antifriction pins are mounted in position to engage and guide the back of the rack-bar and hold it in fixed relation to the pinion. Now by turning the crank 23 the rack-bar 20 can be positively projected and made to swing the box A up about its hinges to a point where the center of gravity of the box falls inside of the hinge, after which the crank movement may be reversed to ease the box down until it comes properly to rest upon the lower box A. Conversely when the upper box is emptied of its contents it may be swung back upon the ground again by turning the crank so as to tip it back off the lower box and then reversing the motion to lower it upon the ground. In either case the box may be assisted over the dead-center point by hand, if necessary, but ordinarily its momentum will suffice for the purpose.

As herein shown the handles H of the jacklevers 14 are made removable and are designed to be thrust through holes 26 in the upper edge of the top box A when open, Fig. 4, so as to prevent the material within the box from starting to fall out before it is completely swung over upon the lower box B, these handles being later withdrawn and used to operate the jacks. An antifriction-roller 27 is also herein shown as journaled in the upper end of each jack-housing to engage the back latchbar 11 and resist the outward pressure of the latter due to the pull of the bars upon it, as shown in Fig. 6. This figure also shows the improved form of spring S provided for normally maintaining the links in engagement with the latch-bars, the same being made of heavy spring-wire bent to suitable form and clamped to the jack-housing by a nut 28 or the like.

The edges of the bag or cloth E require to be firmly held in order to prevent their being drawn down into the lower box B during the compressing operation, and to this end two of the opposite sides of the box are provided with rocking rods 29, which are held by cleats 30,

IIO

so that they can be oscillated through a considerable angle by their ends 31, the latter being bent outwardly to form handles for turning the rods, as shown in Fig. 8. These rods are provided with a number of sharp points 32, onto which the cloth can be pressed and which when the rods are turned down will then prevent the edge of the cloth from being drawn into the box, the rods 29 being locked in position to hold the points down by loops 33, which may be swung up over the handles 31.

To enable the carriage C of the press to be moved easily into and out of the box B, it is herein shown as mounted upon rollers c, and as a further improvement these rollers are herein shown as groovedor otherwise formed to run upon-tracks T, that are extended beneath the press on any foundation.

The press thus described is obviously simple and inexpensive in its construction and weighs so little as to be readily portable, while at the same time it is very powerful and can be made more so within any reasonable limit by varying the proportions of its jack devices. It is convenient to handle and can be rapidly operated without undue exertion, and while more particularly designed as a woolpress is adapted to be equally well used for baling cotton, hay, or any other material which can be packed into it.

In Fig. 11 I have shown a somewhat modified form of press embodying many of the same features of the construction, but in which the separate carriage is dispensed with, the

jack being bolted directly to the sides of the press, which thus take the place of the standards 6. This form of press is designed to be manufactured at still lower cost than the press first described, and to this end is constructed almost entirely of wood, its boxes being bound around with bands formed of wooden beams joined together at their ends by diagonal bolts. The operation of this device is the same as that of the press first described, except that the bale is removed directly from the lower box when the hinged side of the latter is swung back and except that in consequence the bale must be sewed up within its envelop before being removed from the box.

The improved mechanism heretofore described for swinging the upper box upon its hinges may be equally well applied to the modified construction last referred to, if so desired, and this mechanism may also be found desirable in various connections where a simple and etfective power device for raising and lowering a load under similar circumstances is required.

Fig. 12 shows how the press could be utilized and operated in a horizontal or upright position independently of either of the boxes by placing the material to be pressed between the pressureplates and operating the levers as hereinbefore described. The material so pivoted to the top box,

compressed may then be secured in that form by having bands or other wires around the bale and fastening the ends.
