Figs. 19 and 20 are vertical sections of the engaging ends of a bale-holder 8o link, showing another form of gripping device; and Fig. 21 showsone of the bale-holders applied to a bale in elevation.

According to one mode of carrying out my process, I employ lashing plates adapted to operate only upon a portion, or a comparatively small portion of the platen and bale, ,instead, as heretofore, upon the whole. For

this purpose I provide blocks or battens be-' hind them, which blocks I shift as required, 0 by screws, lever or handles from a portion or portions which has or have been compressed to the portion which is to be compressed next, after firstlashing the portion of the bale which has previously been compressed.

To all whom, it may concern:

Be it known that I, DANIEL KEMP WEST, a subject'of the Queen of Great Britain, residing at 23 Saint Mary Axe, in the city of Loudon, England, have invented new and useful Improvements in and Connected with Presses for Baling Cotton and other Goods, (for which I have obtained a patent in Great Britain, No. 18,476, bearing date October 27, 1891,) of which the following is a specification.

The object of this invention is to reduce the prime cost and weight of apparatus for pressing cotton bales and other goods, and another object is by compressing the same into smaller bulk, to save freight in transport.

Instead of, as heretofore, by the usual method, applying the final pressure of the ram, rams or follower at one pressing opera tion to the whole surface of the bale or other package or goods, I apply the final pressure to one part after another, of the'surface, and lash successively each such part after compression, until the whole length or area of the bale has been sufficiently compressed and lashed. Thispressure may with advantage be considerably higher per square inch of pressing surface than heretofore, and I may thus reduce the bulk of the bale considerably below that hitherto usual. The power of the press is thus relatively increased, inasmuch as the area on which it acts at each pressing operation is decreased. I am also in a new finishing press able to reduce the width of the press very materially, if I, as I prefer it, introduce the bale from one end, instead of broadside from the front. The result is that the size, weight and price of the press are reduced, while the density of the compressed bale may advantageously be much greater, and the bulk much less than now.

In any existing press, I may, by the use of my invention, reduce the pressure per square inch of the ram or rams, and yet considerably increase the pressure per square inch of the part of the bale being compressed; but that my invention may be fully understood, I will describe the same in detail, reference being had to the accompanying drawings, in which- Figure 1 is a fragmentary sectional elevation of the upper part of a press constructed in accordance with my invention, illustrating To retain the loosely pressed portion of the bale while the readjustment is made for its final compression, and during such compression, I employ suitable holders, clamps, or

dogs, which may also serve to remove'the bale xco from the half press to the finishing press.

In Figs. 1 to 4, which illustrate so much of the upper portion of a compress as will make my invention clear to those conversant with this class of apparatus, L and L indicate respectively the upper and lower lashing plates, provided with slots or grooves, some of which are made wider at the bottom to receive T- head shaped prongs e, of holders, which prongs are shown in section. In conjunction with the lashing plates L and L, I use blocks or battens a, which are guided in some of the teeth of said lashing plates, and which serve thepnrpose of reducing the height of that portion or those portions of the bale to which they are successively applied, said battens being shifted from portion to portion, as each portion is lashed.

In Fig.1 I have shown the bale B suspended in the holder prongs c, for the introduction of the battens a, the latter being shown in position at each end of the bale B in Figs. 1 and 2, and at the middle of the bale in Figs. 3 and 4:, said battens being guided in the teeth spaces of the lashing plates L and L. Fig. 2 illustrates the next stage in the process, when the press has been worked up and the bale has been compressed at each end and lashed, the holders e, having then been withdrawn. Fig. 3 illustrates the next stage, when the ram has been lowered again, the bale suspended in the holder and the battens a shifted to the central portion of the bale B. In Fig. 4 the press is next shown as worked up again, the central portion of the holder withdrawn, and the central portion of the bale compressed and lashed. The bale being now finished, it is removed, the ram having been lowered and the battens withdrawn, when the central portion of the bale B will swell out and the bale be parallel.

According to another mode of operation, I

may use short lashing plates or platens, and shift the halo to receive the successive pressures in successive portions of its length between such compressing platens or plates. Fig. 5 illustrates in one view such an arrangement when the bale in its holder is inserted in a press provided only with one set of short lashing plates L and L, the bale being pressed first in one portion, say the middle portion, then in another, say an end portion, and then in the other end portion, the portions being lashed in each position of the bale before the latter is moved into the next.

Fig.6 illustrates an example when two pairs of lashing plates are used, the end portions of the bale being pressed first, the end portions of the holder then withdrawn, the lashing effected and the lashing plates shifted to the middle portion of. the bale for compressing the same. Any suitable means may be provided for shifting the lashing plates.

In Fig. 7 I have shown a modification, in which a bale in the holder (which in this case is inserted while the halo is in the halfpress) is inserted in the press between the plates L and L, packing pieces or blocks being put above the upper and below the lower prongs or battensd of the holder, these blocks being for convenience guided in the grooves in the lashing plates L, L. The ends of the halo may, as here intended, be pressed and lashed first, and then the middle, the blocks a being shifted accordingly.

Figs. 8 and 9 refer to bales in which the pressure applied to them is so great, or the substance pressed so delicate that the same or its fibers might be damaged by being cut or forced into the grooves of the lashing plates.

Fig. 8 shows an arrangement of divided lashing plates, the teeth 6 of the holder being made to nearly fit the grooves of the lashing plates L, L, and the blocks or packing pieces a are inserted in the grooves to hold the faces of the teeth of the holder flush with the teeth of the lashing plates, thus producing a plane surface exposed to the final pressure. There being thus no grooves left for the lashing after compression, I divide the hoops or lashings and put them on above and below the bale before the holder is fixed, or I carry them in the holder.

If, as shown in Fig. 8, the ends of the bale are fully pressed and the hoops secured by the latchets 0 while the next. adjoining portions of the bale are partly pressed, I hold the hoops thereon by means of longer latchetsp and replace them at the next pressing operation by the short latchets 0, while I apply the longer ones 13 to the next portion of the halo, and

so on. i

Fig. 9 showsabale held in hoops with latchets 0 and p as in a finishing press, with flat plattens over and under the part of the bale to be acted upon and with sloping surfaces or easy steps to partly press other portions of the bale, and to prevent injury to the halo. The center portion is shown fully pressed and lashed by the latchets 0 and the other portions are then secured by latchets p. The center portion being finished, the bale is shifted and pressed in other portions, which are successively lashed.

To avoid damaging the material operated on by a tooabrupt division line or ridge between a finally compressed portion of a halo and the succeeding adjoining one, I may give a part of the latter a preliminary compression first, thus forming a slight step or slope which is llatened down in the finalcompression of the said succeeding portion, and to retain such preliminary compression of part of the bale, the links which connect the prongs or teeth of the holders are made adjustable in length, by means, for instance, of wedges, clutches, knuckles,-or other gripping appliances.

The foregoing description has relation to a compress in which the compressing devices are so arranged as to admit of the halo being introduced broadside, and so that successive portions thereof maybe compressed and lashed. Of course such a compress must necessarily be of the required dimensions to ac commodate the entire bale.

I have first herein-above stated that by my novel method of compression I am enabled to materially reduce the dimensions of the com-' press by so constructing the same as to admit of a bale being introduced endwise, and

successive portions thereof lashed in se-' supposed to be removed, while in Fig. 10 the front columns are supposed to be removed.

A is the press head, and A the base, U the press cylinder and R the ram.

P and P are the platens, which haveflat surfaces in the middle portion, a series of gen-' tle steps to the left, and one or two steps to the right.

The bale is shown in a holder having sepa-,

rate battens or teeth d above and below, which battens are connected by the links it with sliding joints is, such as are shown in detail in Figs. 17. to 21, and serve to retain the partial compression of the second or other portion of the bale. The links 71. may be divided, or formed with a sliding joint is, and the necessary grip on-or cohesion of this joint may be given by means of wedges Zor rollers Z in a box on-one part of the link.

In Figs. 17 and 18 the box 70 forming. the lower end of upper part it of the link, is provided with wedges Z-which grip the upper end of the lower part hof said link, and are connected to a plate m by means of pins work-- ingin slots. The wedgesbindtightly upon the partit and while allowing the latter to'travel upward, prevent its descent. When the limit of travel is reached thelower narrower part h of h passes up beyond the upper end of the wedges, and the links thus become released from each other.

Instead of the wedges Z, rollers Z may be employed, as shown in Figs. 19 and 20, said wedges or rollers droppinginto suitable wells Z as shown in said Figs. 19 and 20 when the limit of travel is reached, and the narrower part h of the link portion h has passed up beyond the rollers, Fig. 19 showing the rollers in the gripping position, and Fig. 20 in the released position, the part of h which operates with the wedges or rollers being by preference slightly tapered, Fig. 14 showing the bale B and holders in plan view.

In Fig. 10 the battens d are shown in section, while-the dotted lines indicate their poceive reciprocating motion, that is to say, to

the left or under and free from the bale when i the ram has risen sufficiently toclear the battens d of the holder'from the teeth of the feed bars F B, and to the right when the ram is down and the holder battens d have fallen between the teeth of the feed bars, so that the latter carry the bale with them the distance of their travel.

The tables T and T, one at the bale entrance end and the other at the bale exit end of the press, are mounted on stems G which work in guides on the base A. For raising and lowering these tables with the rise and fall of the ram, but at half the speed or thereabout as stated, each table is jointed to the middle of a lever S. The latter is'at one end connected to theplaten P (or to the ram) and at the other end to the base A by means of links H. The upper joint pins of the latter also serve to carry the guide pulley 2. for the chains ch and oh, but this is a mere matter of convenience, for the pulleysmight be mounted in any other. suitable manner.

To give the required motion to the feed bars, I connect them at each end with weights W and W respectively, the latter being the heavier. The feed bars-F B are supported on wheels 'm shown in the detail views, Figs. 12 and 13 and are connected to the weights by chains ohand oh, which run over pulleysi't respectively. The weight W :is lifted by means of the lever Y which has its fulcrum in the bracket K and has a pin 00 at the center of the press where it w0rks in the slot of a link X which rises and falls with the ram.

The acting length of the slot is adjusted to meet the varying circumstances by means of the block y and. adjusting screw 3. The slot permits the ram to rise sufficiently to allow the holderbattens d to rise clear of the feed bar teeth, and then the block y and pin a; in the link slot lift the lever Y and the weight W. The weight W being now free, drags the feed bars to the left and under the bale as the weight W rises and until the press is up, when the feed bars F B are under the bale and some of their teeth exactly under thespace between the holder battens d (Fig. 15) which are over the flat portion of the platen P. The pawl F now falls into gear in the stop F and prevents the feed bars from returning. The pawl gear isshown in the side View, Fig. 12, and under side plan, Fig. 13. pressed portion, the ram is caused to descend, the weight W and the lever Y being sus' pended by the chain until the press is just down, when a discharge arm I upon the table T, Figs. 10, 12 and 13, releases the pawl F,

and the weight W being heavier than the weight W falls and drags the feed bars F B to the right and the bale with them, into the next position for pressing. The lever Y falls with the weight W and resumes its original position. The arm I may be connected to the ram instead of to the table T. The reciprocating action of the feed bars being constant The bale having been lashed in its with each rise and fall of the ram a second bale may be dragged in behind the first one, and so on, thus producing continuous action. There may for this purpose be supplementary teeth 0 on the feed bars (as shown in Fig. 10) and as the lever Y is unfettered by the link X when the ram is down this lever on the feed bar may be connected with hand gear to produce the reciprocating action of the feed bars without working the press ram. This is useful in drawing the bale into the press at the beginning ofthe days work, or after any break in the work.
