Ice shaving apparatus
First Claim
1. An ice shaving apparatus for shaving small particles of ice from an ice block, the apparatus comprising ice block retaining means to retain an ice block having an upper surface and a lower surface, a blade to shave ice from said lower surface of said ice block, rotation means to rotate said ice block about an axis, and a separate axial movement means to move said ice block in the axial direction perpendicular to the plane of rotation such that said lower surface of said ice block contacts said blade where said axial movement means is pneumatically powered and regulated to apply constant pressure against said ice block when said ice block is rotated by said rotation means.

Abstract
An ice shaving apparatus which causes an ice block to be rotated against a cutting blade, the apparatus having a motor which rotates a shaft joined to a drive plate which retains the ice block, the shaft being joined to a piston head within a cylinder, where an air pump provides pneumatic pressure to move the piston head vertically in the axial direction within the cylinder to move the ice block in the axial direction against the cutting blade as the lower surface of the ice block is removed by rotational movement. The air pump is regulated such that a constant pressure is maintained against the piston head.

7. An ice shaving apparatus for shaving ice particles from an ice block having a lower surface and an upper surface, the apparatus comprising:
-
a housing having an upper section, a middle section and a lower section, where said upper section is separated from said middle section by an upper interior wall and said middle section is separated from said lower section by a lower interior wall, said upper interior wall having an aperture to receive a shaft, said lower interior wall having a chute to allow shaved ice particles to fall into said lower section;
a cutting blade mounted onto said lower interior wall adjacent said chute;
rotation means to rotate said ice block such that said lower surface of said ice block contacts said cutting blade such that ice particles are shaved from said lower surface and fall through said chute into said lower section;
axial movement means to move said ice block in the axial direction perpendicular to the plane of rotation and comprising a shaft which rotates and moves axially where said axial movement means is pneumatically powered and regulated to apply constant pressure against said ice block when said ice block is rotated by said rotation means; and
ice block retaining means connected to said shaft and positioned within said middle section. - View Dependent Claims (8, 9, 10, 11)

12. An ice shaving apparatus comprising:
-
a housing having an upper section, a middle section and a lower section, where said upper section is separated from said middle section by an upper interior wall and said middle section is separated from said lower section by a lower interior wall, said upper interior wall having an aperture containing bearings to receive a shaft in a manner allowing said shaft to rotate and to move axially in the direction perpendicular to the plane of rotation, said lower interior wall having a chute to allow shaved ice particles to fall into said lower section;
a cutting blade mounted at an acute angle onto said lower interior wall adjacent said chute such that said blade extends a short distance into said middle section;
rotation means to rotate an ice block having a lower surface and an upper surface such that said lower surface of said ice block contacts said cutting blade such that ice particles are shaved from said lower surface and fall through said chute into said lower section, said rotation means comprising an electric motor which is connected to the shaft extending between said upper section and said middle section;
axial movement means to move said ice block in the axial direction perpendicular to the plane of rotation and comprising a shaft which rotates and moves axially, said axial movement means comprising a cylinder mounted within said upper section and a piston head contained within said cylinder and connected to said shaft, and an air pump to provide air pressure against said piston head to move said piston head and said shaft in the axial direction where said axial movement means is regulated to apply constant air pressure against said piston head when said ice block is rotated by said rotation means; and
ice block retaining means connected to said shaft and positioned within said middle section, said ice block retaining means comprising a drive plate having spikes depending therefrom.
