PRESS- Application filed April 3, 1905. Serial-No. 258,425.

To all whom it may concern:

Be it known that we, JOHN G. .FIDDYMENT,

of Brinkley, Monroe county, ,Arkansas,,and

JOHN J. MoNALLY,of Norfolk, Norfolk county, Virginia, citizens of the United States, have invented a certain new and useful Press, of which the following is a specification, reference being had therein to the accompanying drawin s.

This Invention relates to resses, the invention hereinafter particular y described being designed with special reference to that class of resses em loyed for extracting the juices or liquid or o' from vegetableeseeds, such as cotton-seed, castor-beans, nuts of various kinds, fish, brewers and packing-house prod- 5o scribed, il

nets, and any material containing liquid.

The particular type of press to which this invention relates is that employing, in connection with a suitable press-chamber, a feedscrew working therein and serving to force the material through the press-chamber, compressing the same and expressing the liquid therefrom during the movement of the material through the press-chamber.

One object of the invention is to provide a feed-screw of special form having a portion of its thread so disposed as to establish a receiving throat or space with substantially parallel sides in which the material is primarily received as itleaves the supply chute or hopper; also, toprovide means whereby the width of said receiving-space may be increased and diminished as conditions may require.

A further object of the invention is to provide a check or back-stop at the receiving end of the press-chamber and means for advancing and retracting said check, whereby the material is admitted to the press-chamber and held from being rotated with and by the feed-screw as the latter is actuated; also, to provide means whereby the reach or throwof the check may be varied to suit the width of the receiving-space of the feed-screw.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the nove construction, combination, and arran ement of parts, as herein fully defustrated, and claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinal section through apress embodying the present invention. Fig. 2 is a front end view of the press, omitting the driving-gears and showing the screw-shaft in section. Fig. 3 is a similar view, omittin the check-actuating cam. Fig. 4 is'a detaI perspective view of the head at the front end of the press-chamber. Fi 5 is a detail pers ective view of the chec -actuating cam. ig. Bis an edge view of the same.

Like reference-numerals designate corresponding parts in all figures of the drawings. The improvements contemplated in this invention are designed for use upon the press, (illustrated in Fig. 1,) in which 1 designates a feed-screw provided with as ecial form of flight or thread and mounte to work in a casing 2, preferably cylindrical in shape, said casing being supported by a suitable frame and the feed-screw bein journaled in said frame. A simple form 0 frame comprises a series of bearing standards or pedestals 3, 4, and 5, which are connected and braced by longitudinal beams 6, the journal portions of the feed-screw bein received in said standards and the casing being mounted upon and secured to the beams 6, as shown.

Patented March 27, 1906. I

The feed-screw is mounted to rotate within the casing and embodies a tapering body or drum 7, which gradually increases in size from the receiving end of the press-chamber to the discharge or delivery end thereof, a gradually-contracting annular s ace being thus left between the drum 7 an the inner wall of the press-chamber. Thus as the material is forced through the press-chamber it is compressed more and more, the li uid being expelled through the slatted wal of the casing or press-chamber and remainder of the the press-chamber.

material from which the liquid has been expressed being forced out of the discharge end of the press-chamber through a resistanceplate 8. Stationary bafile projections 9 prevent the material from turmng with the feed screw as it is forced lengthwise through the press. v

In carrying out the present invention the press-chamber or casing 2 is provided at the receiving end with a stationary head 10, through which is formed an opening or gateway 11, in which is mounted a ate or check 12, which by projecting into t e receiving end of the press-chamber acts as aback-stop to prevent the material from turning with the feed-screw as the latter revolves within This check 12 is preferabl in the form of a quadrant, as shown best in Fig. 10, and is hinged or pivotally connected at its inner corner 13 to the head 10 along one end of the o ening 11, which edge is approximately ra ml to the axis of the feedscrew 1. The outer face of the check is rounded or described on the arc of acircle of which its pivot is the center, while the side faces 14 of the check are substantially at right angles to each other. The outer portion of the check is laminated or of sectional construction, as shown, and the lies (shown at 15) are detachable, being heldiin place on the body of the check by suitable fastenin s 16, so that one or more of said plies may e removed as conditions may require, as hereinafter ex lained.

The flig t or thread 17 of the feed-screw is of uniform pitch throughout the major portion of the drum 7; but near the receiving end said thread for a portion of its length is disposed substantially arallel to the head of the press-chamber, sue arallel portion being indicated at 18, w e the extreme end portion of thethread is pitched at a greater angle, as shown at 19, and terminates in line with the head 10. In this way a materialreceiving throat or space. 20 is left between the portlon 18 of the thread 17 and the'inner face of the head 10, the sides ofwhich space are substantially parallel, thus allowing the check to project into the press-chamber and hold the material from being carried around by the feed-screw.

The portion 18 of the thread is of laminated orsectional construction, being made up of two or more .plies or thicknesses 21, secured inplace by suitablefastenings' 22, so that one or more of said plies may beremoved as conditions require. In this wa the width-of the receiving-space of the fee screw may be varied to suit the check 12, the free edge or rounded surface of which swings close to the thread portion 18, as shown m' Figs. 7 and 8. Under varying conditions of the material being fed to the press it is desircreasing the width of the receiving-space 2O and correspondingly increasing or decreasing the reach of the check, which is done b adding or removing one or more of the p ies 15 and 21. The supply chute or hopper 23 leads into the press-chamber directly in line with the receiving-space of the feed-screw, as shown in Figs. 1, 7, and 8.

As the feed-screw revolves the extreme portion 19 of the thread 17 comes in contact with the inner side face of the check and swings the check outward and passes by the same. The check is returned or swun inward by a cam 24, mounted onthe eedscrew shaft or extension outside of the presschamber, which cam acts against the opposite or outer side of the check, as will be apparent in Fig. 7. In this way the check is oscillated or advanced and retracted at the proper intervals. In the drawings we have shown two of such checks; but it is to be understood that one or more checks may be utilized as found expedient. I

In order todis ose the portion 18 of the thread substantia ly parallel to the head 10 the thread is necessarily diverted or defiecte from the normal pitch. In doing this the' portion 18 is preferably made double, consisting of two parts 18 and 18', as shown in Figs. 7 and 8. The space between such portions 18 and 18 does not, however, receive any material, and may therefore be filled up or made solid, if so desired. It will be seen that the portions 18 and 18 diverge from a certain point and converge and come together at another point, and between such v points they each have a difierent pitch.

In operation the material passes from the chute or hopper into the press-chamber and into the receiving throat or space 20, where it is acted upon by the check or back-stop 12,

which keeps the material from turning.

around with the feed-screw and enables said screw to urge the material forward toward the delivery end of the press, the screw acting in connection with the taperin drum to squeeze and compress the material and express the liquid therefrom, the li uid passin through the walls of the press-chamber an the residue or dry pulp being forced out of the discharge end of the chamber through the resistance -plate. As the feed-screw revolves the check is intermittently rocked in and out to admit the material and then back it up, so that the feed-screw may act properly thereon in the manner described.
