rnnss CYLINDER.
Uriglnal application fled m 12, 1921,
vision of a press cylinder of the character described readily assembled from plates capable of rapid and cheap manufacture.
Another object of the invention is the provision of a press cylinder adapted for use in the press which is the subject of my copending application Ser. hi0. 484,103 filed July 12, 1921; this applicatlon being a division of said co-pending application.
My invention possesses other ob ects and features of advantage. some of which with the foregoing will be set forth in the following description of my invention. It is to be understood that I do not limit myself to the showing made by the said descr ptlon' as I may adopt variant forms of my nvention within the scope of the claims.
Referring to the drawings:
Figure 1 isan elevation partly 111 SGClElOIl showing the press cylinderof my nvention.
Figure 2 is a vertical sectional view taken in a plane at right angles with the axis of the press cylinder, the plane of section bemg :5 indicated by the line 22 of Figure 1.
Fi re 3 is an elevation of the upper part of the left end of the press cylinder shown in Fig. 1, the figure being drawn on a larger scale.
Figure 4 is an elevation of a variant form of plate which may be used in my press cylinder. I v
Fig. 5 is a sectional view of the plate shown in Fig. 4, the plane of section being 5 indicated by the line 5-5 of Fig.4.
Fig. 6 is a side elevation of another form of plate in which channels are cut on both sides.
In broad terms the press cylinder comprises a cylindrical assembly of annular,
dished plates preferably made of relatively thin sheet metal by any suitable forming or stamping process. The plates are preferably slightly dished to facilitate their assembly and the ends of the assembly are seated in Serial Ho. 484,103. Divided and this application. filed March 80, 1925. Serial No. 19,308.
heavy end rings which are held together by suitable tie rods so that the assembl of end rings and plates comprises a unit of mechanism easily handled and capable of "quick incorporation with or disassembly from the other members of the complete press. Because of its character, the press cylinder may be readily demounted from the press machine and removal of one of the end rings from the tie rods permits the plates to be separated and cleaned when necessary. Alternate plates are preferably corrugated or grooved to form channels extending from the inner periphery to the outer periphery on both sides and these channeled plates are assembled with intervening plane or even surfaced plates so that the channels in the channeled plates are closed laterally. Thus each channel provides a passage from the interior to the exterior of the assembled fpress cylinder thru which, during the use b the press cylinder, the extracted liquids may pass. Referring first to Figures 1, 2 and 3, my press cylinder comprises a plurality of annular corrugated plates 2 and a plurality of plane or even surfaced plates 3. Each of the corrugated plates comprises an annular plateof relatively thin sheet metal pressed in suitable dies,so that it is crimped, or crinkled, or corrugated, preferably in a radial direction to provide channels extending from the inner periphery to the outer periphery on both sides of the plate. The plates 3, which are assembled between the annular plates, are not corrugated, but present an even or uncorrugated surface to the corrugated plates when the plates are assembled as shown in Fig. 1, so that the channels in the corrugated plates are closed laterally by the even plates.
The even plates may have truly plane lateral surfaces and the corrugated plates may be such as to have the tops of the corrugations lie in parallel planes, but to facilitate assembly and the nesting together of i the plates, I prefer to make the even plates slightly dished, that is, conical or spherical in form, the corrugated plates having a similar dish. This form has a further advantage, in that the dishing permits the'formation of channels of more nearly uniform width at their ends.
On each end of the plate assembly is mounted an end ring 4, suitably rabbeted on the inner periphery to provide a seat in vwhich the plate assembly may be mounted against the central inwardly extending flange 6. The two end rings constitute cylinder heads and are held together by tie rods 7 passing thru the end rin and secured by suitable nuts 8. Pre erably the tie rods, of which there may eonvemently be four, are spaced circumferentially so as to aline the assembled plates as shown in F igure 2.
. length {and that because of the inherent strength of each of the component annular plates, the press cylinder is capable of withstanding enormous stresses. It may also be noted that rotation of any bf the plates due to torsional stresses, were it'to occur, would not alter their effectiveness nor change in the least degree the efiiciency of the structure.
In Fi 4 I have shown a plate 12 which is a modified form of the corrugated plate and in which areformed channels 13, preferably extending radially and closely spaced about the lateral surface of the plate. These channels are produced by a suitable cutting tool, the body of the plate, beforecutting, being of rectangular cross section as shown in Fig. 5, and the plate as a whole being bounded laterally by parallel plane surfaces, or the plate being slightly dished as already explained in connection with the first construction. If the channels 13 are cut in but one face of the plate 12, then the even surfaced plates 3 of the construction first explained are superfluous and need not be used, the assembly of the press cylinder comprising a plurality of the plates 12, the channeled face of one plate abutting against the unchanneled face of the next plate. 1
If desired, channels 14. may be formed on both sides of the plate as shown in Fig. 6, the channels being staggered so that the final result in appearance is not unlike the pressed plate 2 first explained. In the construction shown in Fig. 4 I prefer to make each plate with radially extending lugs 16 having apertures 17 therein thru which the tie rods of the cylinder may be passed.
The constructions shown in Figs. 4, 5 and 6 are preferred where very high pressures are developed in the press since this form of plate will stand greater stresses without deformation than the plate firstexplained.
In the annexed claims I shall use the word even in connection with the plates between the corrugated pl-ates, and by this term it is understood that I include plates ,faces, or by surfaces formi'n which are bounded laterally by plane surportions of cones or spheres, or by any ot er equivalent surface, and which in combination with the corru ted plates laterally-closes the channels t erein to produce passages extendin from theinnerto the outer periphery o the plate.
