Abstract
Apparatus for shaving ice from block of ice and producing selected quantities of finely divided ice particles for use in drinks, refreshments and the like. A power driven rotary shaving head incorporating ice shaving cutters is rotated against a block of ice to shave particles of ice therefrom. The ice block is moved against the shaving head by a pusher mechanism incorporating a wobble plate which grips a transverse guide and support rod under selective manual control. An externally positioned operator lever is manipulated by the user to induce precisely controlled movement of the ice pusher.
Claims17
A feed mechanism for an ice shaving apparatus which comprises:
- (a) ram means for engaging a block of ice to be fed into an ice shaving apparatus;
- (b) an elongate guide rod connected to said ram means;
- (c) means for mounting said guide rod to move axially along a locus which moves said ram means toward and away from the ice shaving apparatus;
- (d) means for incrementally advancing said guide rod to thereby advance said ram means;
- (e) means for initially positioning said guide rod and said ram means to receive a block of ice between said ram means and the ice shaving apparatus;
- and
- means for releasably and controllably engaging said guide rod which includes;
- (1) a loose coil spring about said guide rod;
- (2) means for pulling said spring to a tight gripping condition;
- (3) means relaxing said coil spring to a loose condition;
- and
- (4) means for anchoring one portion of said coil spring.
A feed mechanism for an ice shaving apparatus which comprises:
- (a) ram means for engaging a block of ice to be fed into an ice shaving apparatus;
- (b) an elongate guide rod connected to said ram and
- (c) means for mounting said guide rod to move axially along a locus which moves said ram means toward and away from the ice shaving apparatus;
- (d) a rod actuator member defining a rod passage through which said guide rod extends, said passage loosely receiving said guide rod;
- (e) rod gripping means being interconnected with said rod actuator and defining an opening through which said guide rod is loosely received;
- (f) actuator movement means being moveably connected to said ice receiving vault and adapted to impart canting movement to said rod actuator, said canting movement establishing a gripping relation between said rod actuator and said rod gripping means and facilitating incremental linear movement of said rod actuator and guide rod upon further movement of said actuator movement means to thereby advance said ram means;
- and
- (g) means for initially positioning said guide rod and said ram means to receive a block of ice between said ram means and the ice shaving apparatus.
