Patented July 4, 1950 RIM TO C'OLEECT FIBER AND PREVENT MIXING- WITH JUICE OF JUICE EXTRAC- TOKS Mariiiel Francell Reynolds, Nevada City, Calif. Application September 27, 1947', Serial No. 776,558

means for extractin juices from fruits, vegetables and meats and an improved screen construction and screen housing rim to collect fiber after leaving centrifuge and preventing fiber from mixing with the juice.

In the extraction of juices from various materials indicated, it is common practice to grind the material to a pulp and then subject the pulp to pressure to release the juice therefrom. This method has not given the desired results because the means used in the top or coverplate of the machines used does not prevent the fiber from mixing with the juice, or provide a recess to collect fiber after leaving centrifuge.

It is an object of my invention to provide a machine of the character indicated to provide a machine having a coverplate or top and centrifuge and screen housing rim that will collect the fiber after leaving the centrifuge and prevent said fiber from mixing with the juice.

In the drawings:

Fig. 1 is a cross section view of an electric juice extractor showing improved screen construction rim and coverplate preventing centrifugal force from impelling juice out of container through pulp outlet.

Fig. 2 is an isometric view of centrifuge and screen housing rim.

Fig. 3 is an enlargement of centrifuge screen rim and screen housing.

Referring to the drawings, the numeral l designates an inverted frustoconically shaped centrifugal screen for separating the juice from the pulp, and for centrifugally forcing the pulp upwardly. The upper end of the screen is provided with an annular ring 5b having on its outer side, spaced from its upper edge, an outwardly extendingannular flange 5. nates the outer periphery of saidflange 5. The screen, at its lower end, is provided with a plate I3 and downwardly extending sleeve ll rotatably mounted in an anti-frictional bearing I4. Sleeve I I receives the drive shaft l'2 of anelectric motor 9.Electric motor 9 is housed in abase 6 adapted to rest on a support or floor, and supports at its upper end the juice collectingbowl 24.

Base 6 is detachably secured to the lower end of thebowl 24 by tie bolts 1. Themotor 9 is provided with a conventional form of removable end held in place by the screws '8.

It will be noted that the upper end of thecollecting bowl 24 terminates adjacent, or close to the plane of the lower end of the screen I. Secured to the upper end of the juice collecting bowl,

The numeral 511 desi ziGlaiims. (Cl. 14676) bymeans. of screws I6, is aicover plate; H; which plate extends upwardly and is reduced in diameter at its upper end, thereby forming a horizontally disposed annular flange lla overlying theflange 5 and having its inner periphery l9a substantially in engagement with the outer periphery of the ring 5b above theflange 5.

The reduced portion of the upper end of the cover plate has its interior of greater diameter than the diameter of theinner periphery 19a, therefore it will be seen that an annular pulp collecting channel I9 is provided for the collection of pulp as it leaves the upper end of the screen I, incident to centrifugal force. The pulp, as it is collected in the channel I9, passes through the discharge opening 3 and discharges to the outside of the machine, as clearly shown in Figure 1. The upper side of the cover plate I! is dished downwardly into the upper end of screen I and is provided with an air intake port l8 so a vacuum will not be formed in the collecting channel during the pulp discharging operation.

In the dished upper portion of the cover plate, a spout I5 is disposed to one side of the axis of the screen and through which spout vegetables, or other articles, to be ground and juiced are forced.Spout 15 can be adjusted upwardly or downwardly and can be held in adjusted position by means of the threadedsleeve 22 threaded on the spout, and cooperating with the upper side of the cover plate. The vegetables are abraded and grated by thegrating plate 20, carried in the lower end of the screen, as the plate and screen are rotated. The cover plate, to the outside of the discharge opening 3, is provided with an outwardly and downwardly extending deflecting member 2| so the pulp will be deflected outwardly and downwardly to the outside of the machine. The juice collectingbowl 24 is provided with a downwardly and outwardly extending discharge spout 4 through which juice may be discharged into containers.

In machines of this kind, as at present constructed, fiber piles u with a brushing efiect, however by providing the overlappingflanges 5 and [9a the centrifugal rim or ring at the upper end of the screen forces the fiber into the annular chamber I9 and around the chamber and out through the outlet 3, and at the same time there is no possibility of the pulp passing between the flanges formed on the cover plate and the annular ring flange and thence downwardly into the juice collecting bowl.

I claim:

1. The combination with a centrifugal juice screen ring and spaced downwardly from the upper side thereof and extending outwardly, an inwardly extending annular flange carried by the cover and engaging the annular flange of the ring and the outer periphery of thering above the annular flange of the ring, thereby forming an annular pulp discharging channel above the screen and of greater diameter than the width of the upper end of the screen ring and a discharge opening fOr|pu1p in the wall of the annular pulp collecting chamber and forming means whereby pulp will be discharged to the outside of the cover and to the outside of the bowl.

2. A device as set forth in claim 1 wherein the upper end of the cover is downwardly dished thereby forming a chamber and annular wall and an air intake port in said wall in communication with the annular pulp discharging channel.
