To'all whomz't may'concern: Be it known that IiLOYDGQKIMBERfa citizen of the United Statesrresiding at Sacramento,"in the county of Sacramento and 5 State of California, have inventedcertain new and useful Improvements in Apparatus for Separating the Meat fromfShellsiof Cracked Nuts, of Which the followingfis a specification;

s invention relates toa separating apthe meats from theshe'lls of'cra ckednnts. I The principalobjects of-lthis inventionare to provide an "apparatus which is adapted for operation at an eXtreinelylowcost one wherein the; material tobeseparated isde livered in successive charges to 1 the action r of theseparatingf nedium, thereby, enabling theseparation of material of one charge be tore another charge'is presented} A' fi'irther object i'sto rovide afnov'elform' of material reed Ineo-hani"sin and to provide a means 'for discharging the meats from the apparatus.

' With the above inentio-ncd' and other objeiots invview, the inven'tion consists in the hereinafter 'des'crilie'd,' illustrated in. the ac v companying drawings andpointed oiit-"in the claims hereto appended it" being understood that varions'changes 'inthe for-in, pro portion, size and minor details of construction within the scope of the claims maybe resorted to without departing from the spirit or sacrificing any of the advantages of the invcntion l i To more clearly comprehend the invention, reference is} directed to theaccoinpanying drawings, wherein-- Fig. l -is a view inside elevationof the preferred embodimentof rny apparatus. Fig. 2 is a detailed sectional view of the reciprocating. gate and themeans for open ating the same to deliver intermittent charges of material to successiveelevating pockets. i .i

The frame at one end carries the material receiving h0pper 13 having an inclined bottom 4 falling short ofjconnecting with the front wall 5, thus providing an open 1 o ingwall/ofwhich comprises thelfflight of an cndless conveying belt 7.. The front wall 5 of the hopper is provided with an outlet 8 norrnallyfclosed by a vertii callyreciprocating gate 9 whiohis adapted to rest on'-a"fiight oi the conveyingb elt; The foonveying 'belt is of thef'endl'ess type and is "horizontally disposed and" operates around" supporting rollers or drum's ld to' dispose theupper flight there'oi in snbstan tially horizontal positionin contact with the '70 lowenedge ofthebottom-A and 'lower edge of gate 9., Forwar'cllyfjfrom the "ga't'ef9 'exc tends'anarrn 11 c,arry1ng'{a r0ller 12'adapted torest on theupper flight of the belt and limits the "downward movement of the" gate.

fTho upper end of the, duct 26 terminates 1 j & er "32:11:, One side thereof into which {the-chaff and shells separated from the nut. meats are conveyed by the air'blast.

It will be apparent that I have provided a mechanism whereby intermittent charges of material released from thehopper are de-' livered into successive bucketsof-anelevator l on'vthe registering; Qf the bucke s, with the charge receiving chute, andalso that I'have providedan air blast separator wherein the air current is divided prior to acting on the material to be separated and acts on thema terial from opposite directions,v r
