10. The apparatus for shaving ice of claim 1, wherein said access means includes a door pivotally mounted on said housing for easy access to the interior of said housing.

11. The apparatus for shaving ice of claim 10, wherein said door is mounted by means so it can be quickly and easily removable in its entirety, and said housing is oriented with a 3°

tilt toward the rear so that said door will be self-closing as normally mounted upon said housing.

12. The apparatus for shaving ice of claim 1, wherein said weight means comprises an additional weight which normally rests upon said block of ice to assist the biasing of same by gravity against said casing means.

13. The apparatus for shaving ice of claim 1, wherein said guiding and braking means includes a plurality of rails mounted within said housing for guiding the flow of the ice block in the vertical direction within said elongated housing.

14. The apparatus for shaving ice of claim 11, wherein said brake means further includes an adjustable control for moving at least one of said rails inwardly and outwardly to brake said vertically moving ice block.

15. The apparatus for shaving ice of claim 1, wherein said discharge means comprises a tapered outlet from said casing means for permitting egress of the shaved ice from the device.

16. The apparatus for shaving ice of claim 1, wherein a two speed motor is used for operating said casing means for shaving the ice from said ice block either fast or slowly.

17. The apparatus for shaving ice of claim 16, wherein an operator safety interlock switch is provided with said device for de-energizing said motor upon opening the door to said housing.

18. The apparatus for shaving ice of claim 1, together with advertising material inscribed upon said housing.

19. The apparatus for shaving ice of claim 1, wherein said internal structure of the housing includes a drive motor, a rotating shaft suitably supported from pillow bearings, pulleys and a V-belt for effecting rotation of said casing means upon energization of the drive motor.

20. Apparatus for shaving ice for making snow cones comprising:

an elongated housing;

base means for supporting said housing upon a suitable platform;

casing means for shaving ice particles from a block of ice and dispensing such shavings therefrom;

access means provided with said housing for facilitating service of structure interiorly thereof;

weight means with said access means for providing gravity bias to a block of ice after placement thereof within said housing;

guiding and braking means for controlling the flow of said block of ice within said housing;

discharge means for receiving and dispensing the shaved ice;

said access means including a door pivotally mounted on said housing for easy access to the interior of said housing;
