FRUIT-JUICE IEXTRACTOR.

Application led August 10, 1925. Serial No. 49,329.

This invention relates to improvements in fruit juice ext-ractors, more particularly to devices for extracting the juice from oranges, lemons, grape fruit, and the like, and has for one ot its objects to provide a simply constructed apparatus whereby an extract-or .element may be caused to rotate when pressure is applied thereto, or to the section of fruit disposed thereon, to thoroughly extract the juices therefrom and permit them to fall into a suitable receptacle.

Another object of the invention is to provide a device of this character having means whereby the extracted juices are thrown by centrifugal force away from the extractor element vand thereby prevented 'from lodgement thereon.

Another object of the invention is to pro` vide a device of this character wherein the several parts are separable for cleansing or for the renewal of broken or impaired parts without discarding the unbroken or unimpaired portions.

In the drawings illustrative of the preferred embodiment of the invention. l Fig. l is a longitudinal sectional elevation of the improved device.

Fig. 2 is a top plan view. v

The improved device includes a body preferably cylindrical and formed with vertical sides 10 and with the bottom l1 sloping and disposed intermediate the sides, thereby forming a chamber orspace 12 benea'th the sloping bottom.

The lower edge of the body is preferably supplied with supporting Vfeet 13 and its uper edge inturned in the form of anoverlianging flange 14 surrounding the upper open endmf said body. l

The space'within the body above the floor constitutes the receptacle in which the extracted juices are rst received, and .which escape through a lateral opening 15 and over a sloping spout 16 at the lower end of the bottom 11.

Formed upon the sloping bottom 11 is a perforated hub or boss 17, the perforation being internally threaded with a double or quick action thread, the hub operating as aguard to prevent the extracted juices from running through the threaded opening into the chamber 12, as will beobvious.

Operating through the threaded opening in the hub 17 is a member 18 having double or quick action threads to correspond and By this Depending from the bottom of the iioor l 11 are guide rods 28 and slidable on the guide rods is a cross head member 24, the latter being yieldab y supported on the rods, by springs 25.

At its lower end the threaded member 18 is reduced as shown at 26 and rotatively stepped by the reduced portion in a socket in the cross head 24, the socket having a ball race 27 to receive anti friction balls 28.

At its lower end the reduced portion 26 of the member 18 is formed with an encircling channel'29 to receive a, spring key member 30, to enable the member 18 to ybe detachably and rotatively locked to the cross head.

The springs25 are supported by adjusting nuts 31, to enable the tension of the springs to be controlled.

By this simple arrangement, when a section of fruit, for instance the half of a lemon, orange, grape fruit or the like is placed upon the extractor and `iorced downwardly and held from turning by the hand, the quick action threads of the member 18 coacting withthe quick action threads of the hub 17 will cause the member 18 and the extractor carried thereby to be rotated as theymove downwardly and thus effectually extract the juices and cause them to flow into the trough 21 from which they will escape through the f orifices l22 and be also thrownA by the centrifugal force generated by the rotating extractor a'nd its trough against the side walls of the receptacle chamber and flow' thence .through the opening l15 and spout 16 into a suitable vessel, not shown, venting the wardly.

In the meantime the downward movement of the member 18 will depress the cross headA 24 against the resist-ance of the springs 25, and when the .downward pressure is removed the reaction of the springs will return the the flange 14 prejuices from lbeing thrown up-` member 18 and extractor to its former position when the extracted fruit section can be detached.

The body 10 will be formed of glass, glazed porcelain, aluminum or other noncorrosive material, while the extractor element will likewise be formed of glass, porcelain, aluminum or other noncorrosive material or compounds. 'lhe metal parts will also be of' noncorrosive compounds or plated, or other wise protected from the action of the fruit juices. v

As before stated all the parts are separable for cleansing and readily disconnected and assembled.

Claims:
