Definitions

  • This invention pertains to improvements in presses and more particularly that type employed for expressing of fluids from various materials.
  • the press is of the same general type as that shown in Letters Patent to Anderson No. 731,734 dated June 23, 1903, and the main object of the invention is to provide various improvements in the structural features of such a press whereb better results may be obtained, a more press produced and, furthermore, one which may be readily assembled and disasmuld.
  • Figure 1 is a vertical longitudinal view of the press
  • Figure 2 a transverse vertical section taken on the line II-II of Figure 1 and on an en# larged scale;
  • Figure 3 a similar section taken on the line III-III of Figure l;
  • Figure 1 a top plan view of a portion of the structure at the intake or hopper end of the press.
  • Figure 5 a detail sectional view showing a slight modification of the means employed to effect a coupling between the worm carrying shaft and the driving shaft.
  • the structure is such that in action the shaft which carries thepressing worms is placed under tension whereby wobbling of the shaft is prevented toa greater or les's degree over those presses wherein the shaft has its thrust bearing at the intake end of the machine and the pressure is exerted by the screws toward that end and against the bearing at that end.
  • the structure provides means whereby the shaft and the worms may be readily withdrawn in case o f necessity and a new shaft with new worms substituted without any undue prolongation of the time of shutting down of the machine.
  • the-shell of the press is so formed and mounted that it may be readily opened and each section moved laterally away from the worms and the worm carrying shaft, the arrangement, moreover, facilitating better drainage of the expressed liq uid or yoil as it passes from the shell to ⁇ a collecting trough located beneath the shell.
  • l denotes the main frame of the press which is preferably made as an integral casting in order to afford proper support for the various elements associated therewith.
  • the shell of the press is composed of a series of bars 2 arranged in circular series, the bars in the present instance being carried by, and locked in position upon, heavy transversely disposed castings or rib-like members 3 and 3a.
  • the castings on each side of the shell are alike in form hence a description of one will sufhce for the other.
  • Each cast' ing is provided at .its upper and lower ends with a flat bearing face denoted, respectively, by 4 and 5.
  • Bars 2, as in the former patent to Anderson, are held in place upon the semi-circular seat formed upon the member 3 (or 3a) by shoe bars 6 and 7 and intermediate key bars 8, the latter being drawn to place after the other bars are positioned thus crowding the bars into their proper relation with the inner edges slightly spaced apart.
  • Knife bars 9 are also positioned between each pair of shoe bars 6--6 and 7 7. These knife bars, as will be best seen upon reference to Figure 1, are so constructed that the knives extend inwardl between the flights of the screws hereina ter described.
  • the frame members 3 and 3a at the extreme ends of the shell rest upon tracks or ways formed by bars 10 and 10a having lat upper faces, as best shown in Figure 3. These bars are secured directly to fixed portions of the frame of the machine and form a support for thevshell and its component parts.
  • I provide transversely disposed studs or bolts 11 and 12, which studs or bolts are threaded at one end into upper and lower clamping bars 13 and 14:, respectively, the studs at their opposite ends passpair of clamping bars 15 and 16.
  • the studs y and 15 take against the upper flat faces 4 and 4 while the lowerpair of bars 14 and 16 take against the fiatfaces 5 and 5f.
  • the bars 10 and 108L prevent any downward motion of the shell and the longitudinally extending bars 13, 14, 15 and 16 prevent any transverse movement of the component elements of the shell; thus the shell may be said to be held against movement in three directions.
  • one or both of the sections of the shell may be moved laterally and maintained in such lateral position, if desired, in order to afford access to the interior of the shell for the repla-.cment of any of the bars or for access to the worms or for any purpose.
  • the arrangement is advantageous in that the foots or fine materials extruding through the barrel slots with the expressed liquids are washed downinto the base of the expeller, or the trough formed therein, while in the prior Anderson constructions the foots extruding from the upper half are apt to collect ⁇ and not go down into the base, as the space between the barrel bars and the clamping bar studs is quite restricted.
  • the main frame is provided asis usual with a feed hopper 18.
  • a shaft 19 Extending through the shell is a shaft 19, the .shaft extending laterally to the right of the hopper and likewise extending outwardly beyond the discharge end4 of the press where it coacts with radial and thrust bearings shortly to be described.
  • the shaft 19 is keyed or splined to a sleeve 2() supported in suitable bearings 21 and 22, said sleeve having keyed thereon a driving gear 23 to which motion may be imparted in any suitable manner.
  • a sprocket wheel 24 is secured to the innermost end of the sleeve or member 20, said sprocket being utilized for the purpose of driving the tempering apparatus, not shown, commonly employed in conjunction with a pressof this type where certain materials are undergoing treatment.
  • a sleeve 25 carrying one or more feed worms or screws 26 which tend to draw the materialfrom the hopper and feed the same into the shell of the press.
  • the outermost end of said sleeve 25 is provided with an enlargement 27 which takes against a shouldered portion 28 formed upon the shaft 19. This enlarged portion closes the opening in the hopper through which the shaft extends and makes for rigidity of said member 25 affording proper amount of metal for keying the member 25 to the shaft.
  • an inclined collar 29 Located inwardly of the feed worm is an inclined collar 29 which encircles the shaft andlorated beyond said collar is a series of separated worms or screws 30 spaced apart by suitable washers 31. These pressing worms are keyed to the shaft so as to rotate therewith.
  • a sleeve 32 which sleeve extends throu h a discharge opening the size of which may e regulated in any desired manner.
  • a series of jaws 33 carried by slides 34 is illustrated, which slides may be moved radially inwardly and outwardly and held in their adjusted position by an actuator 35 which is provided on its periphery with a thread with which cooperates a worm 36.
  • This arrangement is not herein specifically claimed as it forms the subject matter of my copending application filed on or about May 28th, 1925, 'Serial Number 33,461.
  • a frame or casting 38 Extending outwardly from the housing 37 of the choke mechanism is a frame or casting 38 which is open at its lower side and likewise preferably provided with lateral openings.
  • a third sleeve 39 is keyed to that section of the shaft 19 which lies within the member 38, the outermost end of the sleeve passing into a hollow box or casting 40 surrounding the shaft and held in position within the outer end of the member 38 by a plate 41, said plate in turn being secured to a flange 42 formed upon the member 38 by bolts 43 which pass through the plate 41 and into the flange 42, said bolts likewise passing through a flange 44 formed as an integral portion of a hollow head or casting 45.
  • the member 4() provides a drainage chamber for any fluid which may be forced outwardly along the shaft between the sleeves thereon, the end ⁇ of the sleeve 39, which lies within the chamber, being notched to permit the outflow of such liquid.
  • the member 45 forms the support for the I radial and thrust bearings employed in connection with the shaft 19.
  • Races 52 and 53 with associated ro1ler ⁇ s'54 provide the thrust bearing for the press, the races being held in roper position by taking against a shoul er 55 formed upon the housing and agalnst a iange 56 formed upon the collar 46.
  • a nut 57 is mounted upon the outer threaded end of the shaft 19 and takes against the fiange 562 the nut being locked in position by any suitable means.
  • A' cover plate-58 and a plate 59 are secured to the outer end of the housing 45. The plate 59, along with the plate 41, acts to form a reservoir for holding'lubricant in and around the bearin s.
  • the cake which is forced out of the press through the discharge opening will, in certain instances, be extremely hard. It has been found in practice that the cake will passalong the outer end of the sleeve 32, follow lthe sleeve 39 and be forced or jammed up into the casting 38 and against the hollow liquid receiving member 40. To prevent such action taking place, I provide a simple means for disrupting the cake. This may consist of two straps or castings 60 and 61, Figures 1 and 2, the ends of which are threaded to receive machine screws 62 to clam them together and cause them to embrace the sleeve 39. By loosening one, or both, of the screws the members 60 and 61 may be moved toward or from the discharge opening or choke of the press according to the condition of the cake.
  • the frame of the press below the shell or barrel thereof is provided with a trough 63 having a gutter or channel 64 formed in the lower portion'thereof.
  • a screw conveyor 65 works in this channel, said conveyor being mounted upon a shaft 66 which receives its motion from any suitable source, not shown. This conveyor acts to thoroughly intermix the foots and liquid passing from the press and'prevents clogging of the pumps to which the material is assed from the channel 64.
  • the press as a ove constructed operates in the main the same as it does in the Anderson patent, above referredto.
  • the material is drawn in by the feed worm 26, is moved through the shell and disrupted and cornpressed by the screws 30, the oil being forced outwardly between the narrow openings between the bars of the shell.
  • the cake is extruded past the choke and is finally discharged through the openings in the frame or casting 38. Due to the action of the screws upon lthe material within the shell a pull or tension is placed upon the shaft 19 toward the right or the intake end of the machine.
  • any form of separable connection may be employed between the inner end of the shaft and the driving mechanism and in Figure 5 I have shown a short hollow shaft 67 to which the driving gear 23 is splined.
  • Said shaft 67 is provided with a plurality of .integral splines 68 on its inner face or bore which interfit with similar splines 69 formed upon tlle outer face of the adjacent end of the shaft
  • the feed screw 26 has a steep or quick pitch whereas the worms 3() have a slow pitch.
  • feed screw or worm 26 has approximately a pitch of twelve inches to one turn'whereas the worms have a pitch approximating four inches perl turn.
  • a press the combination of al bed frame; a pair of horizontally7 disposed ways carried by the frame, one adjacent the intake end and the other adjacent the discharge end of the press; a shell composed of two sections, the line of division between ⁇ said sections lying in a plane extendingflon itudinally and vertlcally of the press, sai sections being supported at their ends on said ways; and means forv securing said sections together.
  • each section of the'shell comprises a series of vertically disposed spaced ribs, each rib having a recess formed in its inner face,l and a series of bars seated upon and secured against the face'of saidrecess; combined with longitudinally extending bars bearing against the outer faces ofthe ribs, at their upper and lower ends; and transversely extending bolts connecting the bars in upper and lower pairs.
  • a-base frame a shaft carried in bearings supported by the frame; a series of worms mounted on the shaft; a longitudinally divided shell carried by the framey the sections whereof are mounted for movement in a horizontal line toward and from each other and to and from the axis of the shaft; and means for rigidly securing said sections together in their assembled or closed position thereby producing a shell which surrounds the shaft and worms.
