To LZ/Z whom t wmy sn/cern:

Be it known that LM/.funn J. vWEBB, a

`citizen of the United States, residing at Minden, in the parish of Webster and State oi Louisiana, have invented certain new and useful Improvements in CottonPresses, of which the following is a specification.

Heretoiiore in condensing 'or compressing cotton in rebaling the same it has been customary to introduce the plantation-bale between the pla-tens of a press, to which power is so applied as to compress and condense the ba e inthe direction Ygenerally in which pressure'w as applied in the first instance in the formation of the plantation-bale.

compressed and condensed in the compresyjsion-press in the direction in which it was compressions of the'bale, and in so doing I operate in the 'first instance upon the mass of cotton contained m the plantation-bale, so

as to change the cross-sectional form withoutmaterial or necessary compression and practically without any material ressure upon the plantation-bale, thereby re ucing the area of the material subjected to the platens of the press, and, in fact, reducing the area of platen required, so that the power of the press being applied over a more limited area it secures a very much more extended pressure per square inch, and therefore a greater compresable.

In carrying out my invention the apparatus may beniade in different forms. l will now describe one which has proved to beef..- iective, reference being had to the accompanying drawings, in which-w Figure l is a side elevation of a press em-A bodying my improvements; Fig. 2y a sectional elevation ci the same; Fig.l 3,` a side view illustrating a safety 'devieeconneoted InA lother instances the plantation-bale has beenI sion energy than would otherwise be availwith the main and auxiliary engines; Fig. 4,-y an enlarged sectional elevation of the safety' device. Fig. 5 illustrates a modification oiv the invention.

The frame A of the press is constructed in. any suitable manner to sup ort the upper platen B, which is preferably t e fixed platen, although .the lower platen() may be fixed, or both may be movable.

The movable platen is operated .from a steam-cylinder D, Ithe piston l of which is,`

provided with a cross-head 2, carrying two.

pins 3 3, to each of which is connectedV a link 4, pivotedby a pin' 5 to a link 6, which latter is connected by a pin 7 to the upper end of the connecting-rod 8, pivoted at 9 to the lower platen. vThe pin 5 is carried by a link 10, which is pivoted at l2 to the frame of the press, and the pin 7 by links 31, connected at I do not herein claim this 30 to the frame; combination of links, which serve .as a means of securing rst an extended movement of the lower platen when a slight pressure is applied and then amore limited movement and increased leverage to secure a very highdegree of pressure, as this is set forth in my apr plication, Serial No. 720,850, .iiled June 16, ,y

1899. ,So far as my present invention is concerned, however, it is immaterial in what manner one platen is brought toward the other or how they may be brought together and separated, as my invention maybe used in connection with any suitable character of' i 'press for this urpose, and I will therefbre not here .more lly describe the details of the press shown. y

' The lower and the upper platen may both be of the same area, but I prefer to combine my appliances in the form of an attachment to a press having an upper platen. B of the full area of the plantation-bale and a lower platen C of more ,limited area corresponding to that-to which the form ofthe bale is changed, soY that if it is desired to convert .the

apparatusfinto one o erating with both platens of the full area o the plantationbale this may be "done by removing theattachme'nt an substituting a wider lower platen.- late for the one employed in connection wit the attachment.

opposite theedges'oi the lower platen-plate, so that when the two plates E laareturned down to a horizontal position the-plantation loov This attaclnnent comprises i two pivoted plates E E with theirpivots 14 1o 5 y bale may extend over the hinges of the same, as shown in dotted lines y.

`VV' hen the platens 'are at their maximum distance apart, the distance between them is considerably greater than the height of the bale-say twelve inches, more or less-so that when the plates E E are turned from a horizontal to a vertical position the particles of cotton in the plantation-bale will be so displaced as to alter the form of the bale practically without compressing it, so that it is reduced in lateral dimensions to a thickness corresponding to the width of the lower platen- -platesa ei hteen inches-but the surplus cotton is isp aced toward the top, so that the height of the vbale is increased, for instance,

between the platens, say, to five feet, therev being no substantial increase in the' densityr of the bale. It will` therefore be noted that the plates E E are not platens or'compressingplates, but are simply displacing-plates,which displace the particles of cotton without materially compressing or condensing the same. When these plates are turned up to the vertical position, they are retained in that position while the cotton is compressed between the platens.' In the construction shown this is accomplished by the upward movement of the lower platen, which is broughtltoward the upper platen to the greatest possible extent, and the bands are then passed through the grooves of the platens (after lowering the plates E) and secured, thus banding the-compressed bale, which is therefore reduced to its most limited bulk and greatest density by a .single pressure in one direction and without space between the platen and the top of the bale, are not necessarily hinged, but may be moved out and in laterally, especially when the bale is introduced from the end of the press. Thus, as shown in Fig. 5, there are two plates E E, which can be moved toward and from the space between the platens by the action of a motor fluid in two cylinders I I, each having a piston 37, connected with a rod 38, connected to one of the plates, the motor fluid being admitted through pipes 39, controlled by proper valves.

When it is desired to employ the press for ordinary baling purposes, applying pressure to the entire surface of the plantation-bade, the u per platen is of the full width shown in the rawings. When, however, itis desired to use the press only in the manner before described, the face of the upper platen will be of the same width as that ofthe lower platen. In order to adapt the press to these changes, the platen-plates a a. may be detachable and separate from the supporting parts,- as shown, beine bolted thereto by bolts secured in any suitable manner.

As before stated, for baling in the ordinary manner the narrow plates arek taken off and wide plates substituted therefor.

While the displacing-plates E E may be operated in any suitable manner, I referably make use of an engine F for each p ate, coinprising a cylinder f, with a piston 16 and piston-rod 17, connected to a cross-head 18,

moving upon suitable guides 19, connected by connecting-rods 20 to a crossin 21, connected by a link 22 to the plate the crosspin being also connected to links 23, the links being so proportioned that the links 23 22 practically constitute a to gle to secure sufficient power to insure the isplacement of the mass of cotton when the plates are brought to a vertical position and also when in line with each other to act as a positive abutment to resist the lateral pressure Vof the cotton when the mass is being condensed between the platen's. To properly support the toggles against this pressure, I make useof tie-rods 25 26, meeting at the pins 27, to which the links 23 are pivoted, the said tie-rods 26 extendinfJr diagonally upward and being bolted to the irame of the press, while the tie-rods y25 extend across the press between the Ltwo pins 27, forming a yoke.

Any -suitable arrangement of pipes and valves may be employed for conducting the motor fluid to the cylinders of the engines and discharging the same therefrom.

It is very desirable to avoid the possibility of vpressure being applied to lift the plates E when the latter are down and the workmen are engagedA in banding the bale .which is compressed between the two platens. To avoid this, I combine with the engines and operating connections of the plates E a safety device consisting of a pressure-regulator G, so arranged that so long as there is pressure beneath the piston in the main cylinder D steam cannot flow to the cylinders of the en gines F. As shown in Figs. 4 and5, the steam-pipe 30 passes tof casing 31 of the regulator G, which has a valve 32, controlling the flow of steam from the pipe 30 to the pipes 33 34, leading' to the en ds oi the cylinders of the engines F. The valve 32 is con-y nected to the regulator-piston 35, andthe space above thc latter communicates through a pipe 36 with the space below the main-pis- -ton of the main cylinder D, so that so long as there is pressure below the main piston the valve'32 will be maintained in its place and vated.
