Abstract

The disclosure pertains generally to shave ice confection machines and processes, and more particularly to a block ice shaving apparatus, system and method whereby an improved blade and blade assembly produce more consistent output with increase machine life.

First claim

What is claimed is:

1. An ice shaving machine, comprising:
a cabinet;
a mechanical drive mechanism having a control mechanism for activating and deactivating said mechanical drive mechanism;
a blade assembly mechanically connected to said mechanical drive mechanism, wherein said blade assembly comprises:
a blade configured to rotate relative to a block of ice when said mechanical drive mechanism is activated, wherein said blade comprises a plurality of openings and a plurality of cutting surfaces adjacent to said openings for allowing ice shavings to pass therethrough, wherein said cutting surfaces protrude out from a surface of said blade, and
a blade holder comprising a plurality of arms that each comprise a pass through portion and a blade attachment portion, the blade holder further configured to detachably retain said blade and couple said blade to said mechanical drive mechanism.

2. The machine of claim 1 , wherein the blade deflects under load.

3. The machine of claim 1 , wherein the blade holder comprises a center hub for interacting with said blade.

4. The machine of claim 1 , wherein the blade is attached to the blade holder and is placed under tension.

5. The machine of claim 1 , wherein a radial measurement from a center of rotation of the blade holder to an attachment structure on said blade holder is less than a radial measurement from a center of rotation of the blade to a corresponding attachment structure of said blade, thereby causing said blade to be placed in tension when said blade is assembled to said blade holder.

6. The machine of claim 2 , wherein the blade is configured to spring back to its original, unloaded position when a load is removed from the blade.

7. The machine of claim 1 , wherein the machine further comprises a spout assembly comprising a spout and an outer shell fitting over and around said blade, said spout assembly having a domed portion for providing a domed round top for the produced shaved ice.

8. The machine of claim 1 , wherein the machine further comprises a safety cover.

9. The machine of claim 1 , wherein said blade is releasably attached to said blade holder, such that said blade is positionable relative to said blade holder by detaching and rotating said blade with respect to said blade holder and then reattaching said blade to said blade holder.

10. The machine of claim 1 , wherein said mechanical drive mechanism is a drive motor located within said cabinet.

11. The machine of claim 10 , wherein said drive motor further comprises an electric motor and a gear box.

12. The machine of claim 1 , wherein said control mechanism comprises foot pedal switch.

13. The machine of claim 1 , further comprising an ice block feeder that is attached to said cabinet and comprises a drive shaft that operates to actuate said ice block feeder thereby forcing the block of ice into contact with the blade.

14. The machine of claim 13 , wherein said ice block feeder includes a blade assembly which comprises dual arms for driving an ice block.

15. The machine of claim 14 , wherein said dual arms for driving the ice block are driven by a motor.

16. The machine of claim 8 , wherein the safety cover comprises a lid that is movably fastened to said safety cover, wherein the safety cover further comprises a safety switch to shut off the operation of the machine when the said lid is raised.

17. The machine of claim 8 , wherein the safety cover further comprises an ice block guide that adds a biasing force laterally to prevent the block of ice from spinning.

18. The machine of claim 17 , wherein the ice block guide is connected or attached to said lid.
