The strainer comprises a reduce the capacity of the compression chamber foraminous plate bent to an arcuate form in cross 45 1. The shaft is provided integrally with collars section, as best appears in Figure 2, to conform 45 I8 at its rear end and I9 at its forward end, which to the path of travel Yof the peripheral portion of are fitted closely into complementary bearings thread I6. The marginal portions of thel screen 20 and 2|, respectively, which are formed in the rest in shallow recesses formed at 43 in the incasting 5. terior wall of the chamber 1.

This rib is received into the tion chamber. The grooves are drained by pasnotches 46 and 41 formed between the endmost 55 Y lugl'sl and 49 of afseries of lugs 50 disposed at from said pulp discharge port to receive material intervals along the sides of casting 5 to provide ,additional support for the screen.
.The bottom of the juicefcollecting chamber 8 below the screen is closed, except at the .forward Vend of such chamber, where it drains intoa spout 52, whichis opposite a pulp discharge spout 4l.
To prevent the pulp from rotating with the screwin chamber 1, the said chamber is preferably longitudinally grooved at 53,:as best' shown in Figure 2. 1 v
The device is usable to extract the juice from practically any fruit or vegetable fed to it in pieces of such size as will be receivable into the hopper 6. The resistance offered to the escape of `the pulp by means of the adjustable screw 39'will determine the extent to which the juice will be extracted therefrom. Y 1,
The fact that the key is unitarily assembled with the handle and screw I5 is a factor'contributing to= vthe facility with which the device may be cleaned. It will be noted that the key constitutes an instantly detachable means for positively anchoring thescrew, and when this key is turned to its figure 4 position, there are very few parts` of the apparatus requiring separate handling in the removal of the screw for the cleansing of the screw and the rest of the apparatus.
