Juicer for separating pulp and juice from fruit
First Claim
1. A juicer comprising:
- juicing means for separating pulp and juice from fruit; and
pulper means including a pulp receptacle having an inlet for receiving juice saturated pulp from said juicing means, juice passage means adapted to pass juice from said pulp receptacle and block discharge of pulp from said pulp receptacle, and an outlet for discharge of pulp from said pulp receptacle, said pulper means further including backing means located in said pulp receptacle, bias means biasing said backing means toward a projected position closing said outlet, said backing means being movable against said bias means into a retracted position opening said outlet, said pulper means further including a pulper piston reciprocable in said pulp receptacle between a retracted position, enabling entry of juice saturated pulp into said pulp receptacle through said inlet, and a projected position closing said inlet for compressing juice saturated pulp in said pulp receptacle against said backing means whereby juice may pass through said juice passage means, and pulp may be discharged through said outlet upon movement of said backing means against said bias means and into said retracted position responsive to accumulation of compacted pulp against said backing means resulting from successive reciprocations of said pulper piston.

Abstract
A juicer for separating pulp and juice from fruit. The juicer comprises an indexing assembly for accepting fruit from a conveyor system and urging the fruit past a cutter to halve the fruit. The cut halves are arranged in opposition to a pair of reamers which remove juice and juice saturated pulp for passage to a pulper assembly. A piston system in the pulper assembly is adapted to compress the juice saturated pulp and contemporaneously discharge compressed pulp. Features include agitators in the conveyor system to facilitate movement of the fruit to the indexing assembly, flexible cups for receiving various sizes of fruit, and operation of the indexing assembly in timed relation to movement of the reamers.

5. A juicer comprising:
-
juicing means for separating pulp and juice from fruit; and conveyor means for conveying fruit to said juicing means, said conveyor means comprising a fruit receptacle for fruit, said fruit receptacle having a laterally opening discharge outlet;
a rotatable generally circular base in said fruit receptacle inclined toward said discharge outlet whereby round fruit tend to roll into said discharge outlet and characterized by a plurality of radially directed protuberances projecting out of said base and adapted to engage and bump fruit in said fruit receptacle whereby the fruit may be agitated and swept toward said discharge outlet; and
drive means for rotating said base.

6. A juicer comprising:
-
a juicing means for separating pulp and juice from fruit; and pulper means including a strainer receptacle having apertures for passing juice and blocking pulp, having an inlet for receiving juice saturated pulp, and further having an outlet for discharging compressed pulp;
a backing piston on said strainer receptacle;
bias means biasing said backing piston inwardly toward closure of said outlet;
a pulper piston in said receptacle in opposed relation to said backing piston, said pulper piston being movable inwardly toward said backing piston to close said inlet and compress any juice saturated pulp located between said pulper piston and said backing piston whereby juice may escape through the apertures in said strainer receptacle, and whereby the resulting compressed pulp tends to urge said backer piston outwardly toward said outlet for eventual escape of said compressed pulp out of said outlet, said pulper piston being movable outwardly away from said backer piston to open said inlet and allow a fresh quantity of juice saturated pulp to enter said strainer receptacle; and
drive means for reciprocating said pulper piston inwardly and outwardly within said strainer receptacle. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
