' Ollie Giliiatt, Washington, Ind, assignor to Vin ccnnes Packing Corporation. Vincennes, Ind.,

a corporation Application October. 2, 1933, Serial No. 691,774 a enm- (ci. 100-48) This invention relates to a device peculiarly adapted to the separation oftomato juice from beneath and mounted in the bearings l6 suspendthe pulp or pomace of the tomatoes.-

The chief object of this invention is to provide apparatus whereby parts may be readily disassembled for cleaning and which have a greater efllciency than the apparatus set forth in the copending application entitled "Process and apparatus for producing tomato produc Serial No. 489,332, filed October 1'7, '1930, which is now minating in hopper type intake -25, cooperates 0 Patent No. 1,989,231, dated January 29, 1935.

The chief feature of the invention consists in the adjustable throat construction.

Another feature ofthe invention consists'in the adjustable throat construction in combination feed screw associated with a substantially tubular enveloping screen.

Preferably the screen is of the general character illustrated and described in the before mentioned copending application.

Other features of the invention will be pointed out more specifically hereinafter.

The full nature of the invention will-be underbers l2, the worm wheel"l5. Positioned thereingly supported from the members I l is the shaft l9 mounting a worm 18.- One projecting end of the shaft 1 9 mounts a pulley, sprocket, or the like, 20, whereby the device may be driven.

An end plate structure 2 I in combination with a cylindrical portion 22 having an opening 23 therein from which projects tubular portion 24 terwith the spacing collar 26 suitably supported as at 21 upon the frame work to form a receiving chamher for the crushed or torn tomatoes.

Rotatabiy supported in the chamber 28 formed within the aforesaid structure, is a screw, gen- 15 with a variable pitched conveying and expressing erally indicated by the numeral 29,.having an end 1 plate structure 30 that is apertured as at 3! and threaded to receivea driving, collar 32 having asquare or similarly outlined opening 33. The

In the drawing Ill indicates supporting standards in turn supporting a frame structure I I coinprising a pair of parallel members which at one end are connected by the-transverse supports I! which rotatably support in the bearings l3 thereof the shaft l4 having the squared end Ma, and upon which is mounted between said mempending application for Letters Patent. This screen is non-cl g ing.

A screen support, indicated generally by the j numeral 34, is provided with a pair of apertures rods 36 mounting nuts 31.. Each rod fibfis pivotally'supported at 38 in the bracket est-sums secured as at 40 to the frame members ll.

Thescreen is seated in the recessed portion-Bi oi the support member 34 and the free end of the screen bears against the shoulder 42. Thus the screen gs clampingly supported between the collar it and the screen support member. 'The end of the screen is prevented from pitching downwardly by reason of the outwardly projecting portions 44 on the support member as andresting upon the frame mem- 35""an'd extending through the same are the 35 To prevent rotation of the screen-see Figs. 6

and 'I-lt is provided with at leastone notch in -its end. Preferably two diametrically positioned notches in each end are provided and are indicated by the numeral II. The screen support at each; end includes lugs I2 herein shown as pins, that extend radially inwardly and are received by the notches when the screen is seated. To

vided with a handle 46 whereby the same-may' be readily removed when desired. The cover together with the structure, hereinafter set forth,

forms a separating chamber. The lower portion of said chamber includes a tank like arrangement 41 having inclined bottom 48 inclining downwardly toward an outlet 49 which may or may not be controlled by a valve not shown. The tank 41 and cover 45 form a separating chamber surrounding the screen 50. As shown clearly, the screen is substantially cylindrical and open at both ends and as set forth herein before. The feed screw is of substantial uniform diameter throughout its length, except that the spacing, between the portions of uniform diameter, gradually decreases from the inlet end of the machine to the discharge end of the machine, and the root or base diameter of the groovedportion between each uniform diametered portion is of gradual increasing diameter from the inlet to the discharge end of themachine. The result is as follows;-

As the material is supplied to the machine, it is conveyed by the feed screw from the receiving chamber 28 to the separating chamber coextensive therewith and as the pulp is gradually forced toward the discharge end of the machine which is at the right in Fig. 1, the material is gradually compressed within the screen by reason of the increase in diameter of the central portion of the screw or reduction in depth of the groove before mentioned, and by reason of the decreasejn the spacing between the threads at successive positions so that the pulp compresses inits forward travel through the machine. The result is that the juice is gradually forced from the pulp and through the screen apertures, and the correspondingly increasing portion of the solids in the remaining pulp is subjected to greater pressure for further juice separation so that by the time the pomace is ready for discharge at the discharge end of the machine, practically all of the desired juice content has been expressed by the feed screw through the screen, leaving only the pomace or relatively solid material of the tomatoes for discharge. The discharge end of the machine is provided with an adjustable throat construction for varying the degree of back pressure exerted upon the pomace and thus there is obtained the desired degree of separation between the pomacev and the juice. This means for adjustable throat construction is shown most clearly in Fig. 3 and cooperating parts thereof are shown in Figs. 1, 2, and 5.

The screen end support member 34 is centrally apertured and the same is threaded as at Threadedly mounted therein is a throat sleeve 52 which at one end and the outerj'end is-provided with a peripheral series of spaced notches or recesses 53. The other end of the sleeve is provided with-an outwardly extending peripheral portion 54 which is provided with the conical face has detachably associated therewith a throat asof the conical faces 55 and 58 are shown the same.

It will be apparent that as the sleeve throat is rotated or threaded inwardly or outwardly with respect to the screen end support member 5 34, the. width of the annular channelbetween faces 55 and 58 constitute the discharge outlet for the pomace is.correspondingly decreased or increased respectively.

Pivotally supported by the pivot member 60 is a dog 6| which has a finger engageable portion 62 and a locking tooth 63, the latter being adapted -to seat in anyone of the selected recesses 53 of the adjustable sleeve throat. The member 60 extends through the opening 64 of the locking dog and is suitably secured to the screen and sup' port member 34 and preferably near the upper portion thereof for gravity locking of the dog.

The exposed end of the feed screw is suitably apertured and the same is threaded as at 65 and threadedly mounted therein is a stub shaft 66. The shaft 56 is rotatably supported in a bearing 51 from which extends a pair of diverging arms 68 with inturned ends 69, the latter being rigidly secured as at 10 to the screen end support member 34.

The resulting construction is such that the free end of the shaft is supported by a detachable bearing which may be readily removed and upon removal, the nuts 31 may be removed and the entire end support 34 with the adjustable throat may be axially removed from the machine. Then the screen may be removed following removal of the feed screw construction. This permits access to be had to the entire interior of the machine for cleaning, it being understood, of course, that the cover 45 has been initially removed.

While the invention has been described in great detail in the foregoing specification, the same is not to be considered as of restrictive character but merely by way of illustration and modifications, which will readily suggest themselves to persons skilled in this art, are all considered to be within the scope of the invention, reference being had to the appended claims.
