PRESS.

Application filed August 31, 1915, Serial No. 48,155. Renewed January 26, 1917. serial No. 144,773..

To all whom it may concern:

Be it known that I, JOHN C. FIDDYMENT, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Presses, of, which the following is a specification.

This invention-relates to improvements 1n presses and-has particular reference to a press for extracting fluids from matter by compressing such material during its travel througha chambered receptacle whose area preferably decreases toward the discharge end of the press.

The means employed to effect this decrease in the area of the chambered receptacle may vary it being common to sometimes produce the tapering chamber by tapering the body of the conveyor or by taperin the shell about the conveyer.

eretofore it has been common in presses to employ conveyers having spiral threads either broken or continuous by means of which the material to be pressed is advanced through a perforated, slatted or foraminous shell or casing. In presses of this character it isnot infrequent that the material will so cling'to the body of the screw that it will simply revolve therewith and not-advance,

or in mushy or semi-solids will even some- .times flow backward toward the feed-in- My invention has for its object to provide a press with an improved construction of conveying means whereby toeither entirely avoid the use of an advancing screw or simply to employ such screw at or near the define the limits or scope of the invention.

discharge end and to positively push and-- force the material forward during each revolution of the machine. 1

Another object of the invention is to provide an improved conveying means having a revolving body with a plurality of annular channels which latter are blocked, and provided with lateral escapepassages to afford communication between one channel and another.

The invention therefore may be used in connection with inclosing shells or casings that vary widely in construction.

With these and other objects in view, the accompanying drawings illustrate embodiments of the inventive ida, it being understood however that tlie drawings do not pressed fluids.

In the drawings, Figure 1, shows a vertical longitudinal section through a machine embodying the.

invention.

F1g. 2, illustrates a cross-sectional detail through the same,the section being taken on the line 2--2 of Fig. 1.-

Fig. 3, .shoWs in perspective, one of the detached division plates.

Fig. 4, illustrates a longitudinal section through a machine embodying the invention but'of a slightly modified form, and

Fig. 5,- shows a cross-sectional view through on the line 5--5 of Fig. 4.

In the present disclosure of the invention I make use of a casing or shell and some other details shown in my prior Patents 1,049,834 and 1,069,404 to which the usual feed-in-hbpper is attached so as to efiect a continuous feeding ofmaterial to be pressed. Y

In carrying out my invention I-employ a shell or casing l0, which may be formed of sections 11, so as to conveniently provide the latter,-the section being taken a series of circumferential openings or escape passages 12, forthe outlet of the ex- In the present instance these shell or casing sections. are shown secured together by means of long bolts or bars 13, which latter pass through suitable eyes 14, that are cast on each section, as clearly shown in Fig. 2. By n eans of-this sectional construction of shell and easing, liners 15, of suitable size may readily be inserted between the sections to vary the area of the openings or escape passages to suit the character of the material that is being pressed.

On the interior of the casing or shellI provde a body 16, which extends longitudinally of the shell and which is suitably mounted on a shaft 17, that is sustained in bearings 18 and 19, respectively. This shaft may be driven in any suitable manner-to effect a revolution of body 16 and alsov'to' revolve a gear 20,carried thereon for a purpose which will presently be described. 0

' The body 7 and the inner circumferential wall of the casing or shell sectionsiare so shaped as to provide a tapering chamber 21, through which the materials are conveyed so as to effect a compression thereof 'to express the fluids. V

One of the objects of my present mvens in registration with an annular channel onv tion is to provide improved means for ad-- a series of annular circumferential channelsv 23. Each annular channel is provided with one or more cross-wise batlle plates 24, and at each baffle each partition has a side opening 25, that forms a lateral outlet or communication from one channel to the next channel in advance of it, so that material in any given channel 23, must remain in that channel until it passes through one of the lateral openings or outlets 25, into the next channel,

The number of these partitions and annular channels on the body 16, may be varied, but in the form of device shown in Fig. 1, they terminate somewhat near a point midway between the ends of the body 16, and

screw thread 26, that extends toward the discharge-end of the body, which threads will also convey the material through the tapering chamber 21, and continue its pressing.

In order to compel the material to discharge from one annular channel into an-,

other through the lateral openings, I provide a lower shell or casing partition 27, at the feed-in-end and beneath said channels and partitions 22.

A shaft 28, extends through the lower shell. and carries a plurality of heads 29, each of which latter register with and project into an annular channel around the body 16. These heads 29, may also vary in shape but in the form shown in Fig. 1 they are circular so. that their circumferences may travel in close proximity to the circumference of the body 16. i

A gear 30, is provided on shaft 28, which meshes with and is driven by the gear 20, so that when the body'16, revolves, the heads 29, will also revolve, but in a reverse direction,each head turning in a vertical plane the body.

-As each head 29, travels in a channel 23,

- around the body 16, and each channel has one ormore cross-wise baffles 24, it is obvious that cross-wise notches 31, must be provided in the heads into Which said baflies -may project during each revolution. In the sectional view shown in Fig. 1, the notch 31, in the innermost'head 29, and the baflie 24,

60 in the innermost channel are illustrated as coming into registration, so that close contact between the heads and channels may be .maintained. a

It will be noted that the heads 29, are

slightly spaced by means of washers 32, so

said body is then provided with a tapering they will be held in alinement with the respective channels.

Inasmuch as the heads 29, are spaced to enable the edges of the partitions 22, to project between them, such spaces, unless closed, will permit material to pass therein and back up at the feed end. To overcome this I provide a plate 33, with a concave upper edge 34, which closely fits the spaces referred to and whose curved edge 34,- engages the.

curved circumferential edge of the partition 22, so as to effectively close said spaces.

In the operation of the machine the material is continuously fed to the outermost annular'channel 23-, and during rotation of the body 16 and the heads 29, the latter, by entering and filling the channel, will prevent the material from traveling around with the body in one direction whilethe baflle 24, will prevent the material from flowing around the channel in the reverse direction. During rotation, however, the baffle gradually approaches the head consequently the material in the channel between the battle and head will be subjected to compression and obviously will be forced laterally through the opening 24, into the next annular channel. When the baflle is in position to pass over the head beneath it, the latter will present its notched edge 31, to receive the ba-flle 24, and allow the latter to pass. Immediately upon passing the battle the head again compresses the material in the annular channel and causes it to seek outlet through the lateral opening into the next channel. This operation is repeated so that the material will be held against movement in a circular direction about the body and only shift laterally through the side openings 25, as the baflles and the circular heads are brought toward each other in each revolution. By this means the material is positively forced from one annular channel to another and thereby advanced toward the discharge end of the machine, where the screw threads 26, if present will take up the material and continue its advancement and compression because of the continued reduc tion in the size of the tapering chamber 21.

A cone-shaped head 35, is providedat the discharge end of the shell and is adjustable on the body to enable the outlet 36, to be increased or decreased as desired.

In the form of device illustrated in Fig.

4, the body is formed of sections 38, and the.

afiles 42, substantially those designated 25, in Fig. 1,

like those designated 24, in Fig. 1 are employed and the lateral openings 43, like are also provided inthis modified form. I

The heads 41, in the modified form are provided with a series of circumferential recesses 44,-the curved walls of'which recesses serve as stationary abutments to pre- 'vent rotation of the material with the body The circumference of and the partitions' each head 41, between two recesses is concave as at 46, so as to seat against the curved body and be held against, rotation during each revolution of the body. When, however, a baffle engages the curved wall of a recess, the head will be givena partial rotation until saidbafile has passed whereupon ment.. 20

said head will In this modified form of device the in- V termittently-movable heads 41, areall idle on a shaft 47 either of them u obviouslyis'gjonce during each revolution of and turn independentlyi' when the body.

It will-lbe'lnoted that as the capacity of the annular channel is greater than the area of the: next channel, the material must be coinpressedto forceit into the s'eco channelfiand still further compressed? force it into the third channel. way the fluids are expressed from the mate rials and the transfer of the material from one channel to the other is positive during each revolution.

Beyond the series of annular ehanniils the I body is hollow and the fluids may thus find -ried on a an escape through the annular spaces 48, formed between the section's. An ad ustable cone-head49, at the-discharge-end will choke the outlet 50, so as to maintain the compression .of the material after it leaves the annular channels.

The body 38, in the modified form is car;-

The plates 33, with concaye upper edge 34, are also employed in the modified device to engage the partitions 39, and prevent escape of material-between the heads 41.
