SPEOIFICATIONfOrming part of Letters Patent No. 581,600, dated April 27, 1897.

Application filed Deo'a i press of novel and exceedingly simple construction for pressing cotton, wool, hair, and the like into bales.

The invention consists,substantially,in the construction, combination, location, and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in ihe accompanying drawings, and finally specifically pointed out in the appended claims.

Figure 1 is a plan view of a press embodying the principles of my invention, parts of the supporting-frame and driving-shaft being broken away. Fig. 2 is avertical central longitudinal sectional view of the same on the line 2 2, Fig. 1. Fig. 3-. is a view in side elevation of the cap-plate. Fig. 4 is a view in side elevation of a slightly-modified form of press embodying my invention,'parts being broken away, parts'broken out, and parts in vertical section. p The same part is designated by the same reference-sign wherever it occurs throughout the several views. I

In carrying out my invention I provide a suitable framework A, upon which the press The press comprises a receiving-chamber D, into which the cotton or other material to be pressed into a bale is introduced,and a cap-plate or cover M. The chamber D is preferably'open-ended, as shown, and the cap-plate M is arranged over one of the open ends of said chamber,with the inner surface thereof projecting into said chamber. The object ofmakin g this chamber open-ended is to provide a practically unobstructed passage from the cap-plate through the chamber, in contradistinction to the class of presses in which the material in its passage is compressed against something, whether station am or movable.

, receivin g-chamber.

17,1896. Serialfio, 15,993. (some) Thecapplate M is provided with a slot or opening N through the same, through whichthe material to be pressed is introduced to the Preferably, though not necessarily, this slot is arranged radially in said cap-plate. The surface of cap-plate M,

which is arranged to project into the receivl ing-chamber, is preferably formed to project to a progressively-increasing depth into the said chamber from one edge of the slot or opening N to the other edgethereof, as most clearly shown in Fig. 3.

From the foregoing description it will be seen that by continuously introducing the material to be pressed into the receiving-chamher audsimultaneously therewith relatively rotating said chamber and cap-plate the material is subjected to a progressive pressure, due to the action thereon of the peculiarlyshaped surface of the cap-plate, which is arranged to projectinto the receiving and compression chamber.

I have shown, the inner surface of cap-plate M as being formed into a. spiral, but I do not desire to be limited thereto, as rnyinventionincludes any arrangement of surface which projects a progressive depth into the receivin g-chamber from one edge of the slot or opening N'to the other.

the chamber D and the cap-plate M maybe employed. In the particular form shown, to which, however, my invention is not limited, I rotate the chamber D, and to this end'I mount a gear-wheel J thereon, arranged to be engaged and driven by a gear K upon a suitably-arranged shaft L, adapted to receive rotation from any suitable or convenient source. Of course it will be understood that myinven tion is in no manner limited or confined to the particular form or arrangement of gearing shown. In the particular arrangement shown, to which, however, my invention is not restricted, and wherein the chamber D is rotated, said cap-plate is statiohariiy mounted, and a suitable bearing is provided, in which the chamber D is monnted to rotate. l have shown a convenient arrangement, to which, however, I do not desire to be limited or restricted, wherein I mount a cylindrical casing B upon the frame A, said casing being Any suitable gearing for relatively rotating of the flanges G E may be employed.

securely bolted to said frame, and the chamber D is arranged to be received in said casmg. tive arrangement of the chamber and casin g, wherein I provide said casing. with an inwardly-projecting rim or flange (I, the chamber D being provided with a similar peripheral rim or flange E, adapted to restupon said rim or flange 0. Any suitable means for reducing friction between the bearing-surfaces In the form shown, to which, however, I do net'desire to be limited or restricted, I introduce a wearing-strip F-say, for-instance, of brassbetween the bearing-surfaces of said flanges. In order that the chamber may be properly supported within casing B, saidehamber is arranged to bear peripherally against the inher wall of said casing, and preferably, in order toreduee friction to the lowest point, such peripheral bearing is provided only at the ends of the chamber D, as indicated at G H. The cap-plate M is securely bolted or otherwise rigidly secured to the casing B in almanner permitting the removal of such capp ate.

The mode of operation of my press will be readily seen and understood from the foregoing description and is as follows: The chamber D is first filled with the cotton or other material to, be pressed, either by hand or otherwise, and then the cap-plate M and said chamber are assembled with the peculiarly- I important functions.

fects a continuous drawing or feeding of the vshaped cam or spiral surface of the cap-plate projecting into the chamber. Now by imparting a relative rotation to said chamber and cap-plate and simultaneously therewith introducing additional material to said chamher through the slot or opening in the cape plate such relative rotation accomplishes two In the first place it efadditional material into the chamber D, and, in the next place, such relative rotation imparts to the material thus continuously introduced to the chamber a progressive pressure, due to the action of the peculiar shape of the siirface'ofcap-plate M, projecting into the chamber. The material to bepressed may be .delivered by hand or in'auy suitable or convenient manner to the slot N, and in order to facilitate its entrance through said slot or opening into the chamber I may provide the far edge of said slot or opening with'an upturned flangepr lip 0, Fig. 4,01, if desired, I may mount a suitable antifriction-roller P, Figs. 1 and 2, adjacent to the far edge of said slot or opening, and which serves as a guide for the material. If desired, and as shown, this 6o roller may be cone-shaped. By reason of the relative rotation of the cap-plate and compress'ion-jch'amber and the coincident introduction of the material to'said chamber through the opening in said cap-plate it will be readily seen that the material'is formed into spiral layers and-is, asabove explained, subjected to a progressive compression. It will also'be I have shown a simple and efiicient relaseen that on account of such relative rotation of the cap-plate and chamber an unfilled space in the bale is left at the axis of 'ii tidiZiOll. In order to remedy this, and with the ob'ect of producing a solidly-formed bale, I pre erably contract the internal diameter of chamber D,

as most clearly shown in Fig. 2, from the end thereof adjacent to the cap-plate to the other or delivery end of such chamber. By-this provision I impart a lateral compression to the body of thebale as the material proceeds through the chamber, thus efficiently compressing the bale into the unfilled space at tlieaxis ofrotation. The formed and compressed bale emerges from the open.v end of the chamli'er D, and by-suitably 'arrangin'ga cover R over said delivery end ot the com pression-chamber-as, for instance, by telescoping a sack or covering of bagging orother suitablemat-erial over such delivery end.-it

will be seen that the bale as'it emerges from.

the chamber D and of the delivery-tube 262,?

which resistance is exerted in a manner which does not injure in any manner the fiber of the material being pressed, notwithstanding the "enormous pressure to which itis subjected. Of a course in the case of a cont-actin g chamber an additional resistance is also provided. In order that the resistance may not be too great, I

preferably provide the chamber D and also the extension Q with a polished inner surface. I vary the resistance to the pressure exerted by cap-plate M,- and hence vary-the d, gree of compression to which the bale is su jected,

the longer said extension the, greaterthe pressure.

The extension Q, which may be formed integral with or suitably supported by the chamher-D, forms a convenient temporary sup port for the covering R in position to receive the halo as it emerges from the machine.

From the foregoing description it will be seen that I provide a press that is exceedingly simple in construction and eflicient in operation.

By varying the. length of extension Qf rro Ills;

While I have shown and described a specific embodiment of means for. carrying-the principles of my invention into practical op eration, I desire it tobe distinctly understood that the specific form shown, while the best form in which I at present contemplate car rying my invention into practical operation,
