Abstract
Abstract A hand held cheese grating device having a cylinder body fitted with a stationary lower grating member upon which a slug of cheese is rested and caused to be grated as an upper grating member is relatively rotated by means of a drive shaft. Cheese gratings fall through openings in the lower member and exit from the bottom of the cylinder. A compression spring constantly urges the upper member down upon the cheese. Any cheese gratings that might be forced upwardly through perforated grating formations to the upper surface of the upper member are swept over the edge of the latter to the openings in the lower member by means of a terminal arm of the spring, relative to which the upper member rotates. A container for receiving the cheese gratings is detachably mounted to the bottom of the device. The drive shaft is subject to manual or motorized operation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
40 words
A hand held cheese grating device as in claim 1, wherein the upper member is a disc having a plurality of perforations about each of which at the underside of the disc depend sharp edges defining the upper grating surface.
Claim 2
Dependent Claim
52 words
A hand held cheese grating device as in claim 2, wherein a clearance spaces the periphery of the disc from the surrounding wall of the cylinder so as to allow gratings of cheese to drop over the edge of the disc and through the clearance to the holes in the lower member.
Claim 3
Dependent Claim
52 words
A hand held cheese grating device as in claim 1, wherein one end of the spring is fixed in the cap, and an opposite end of the spring extends radially across the upper surface of the disc to define a sweeper arm relative to which the disc is rotatable by the shaft.
Claim 4
Dependent Claim
24 words
A hand held cheese grating device as in claim 4, wherein a manipulative crank handle is provided on the shaft externally of the cap.
Claim 5
Dependent Claim
32 words
A hand held cheese grating device as in claim 4, wherein a coupling drivingly connects a motor with the shaft, and coupling means mounts the housing of the motor with the cylinder.
Claim 6
Dependent Claim
39 words
A hand held cheese grating device as in claim 1, wherein a container is detachably mounted over the bottom end of the cylinder for reception of any cheese gratings that might fall through the holes in the lower member.
Claim 7
Dependent Claim
33 words
A hand held cheese grating device as in claim 7, wherein the container is formed of transparent material so that it may be visibly determined when the container is filled with cheese gratings.
Claim 8
Dependent Claim
25 words
A hand held cheese grating device as in claim 7, wherein the container has a broad bottom providing a stable standing base for the device.
Claim 9
Dependent Claim
43 words
A hand held cheese grating device as in claim 7, wherein the cylinder is formed of transparent material so that it may readily be determined when a slug of cheese entered into the cylinder has been grated down to a size requiring replacement.
Claim 10
Dependent Claim
239 words
A cheese grating device containing an open-ended cylinder adapted to receive through one of its ends a slug of cheese, a lower grating member and an upper grating member disposed in the cylinder respectively defining a lower cheese grating surface and an opposed parallel upper cheese grating surface, the lower member being stationary and having a group of holes through which gratings of cheese may pass, the upper member being rotatable and axially retractible relative to the lower member, a cap closing over the upper end of the cylinder having an axial bore, a drive shaft fixed at its bottom axially to the upper member and projecting in its upper portion slidably through the bore in the cap, means externally of the cap for rotating the shaft, a compression spring loosely encircling the shaft and limited between the cap and the upper member, the spring constantly urging the upper member together with the shaft axially inwardly of the cylinder, an external abutment on the shaft having cooperation with the cap to limit the extent of inward disposition of the shaft and upper member to a position in which the upper member is spaced a predetermined normal clearance above the lower member, the upper member and shaft being axially retractible against the bias of the spring to the extent of the axial dimension of a slug of cheese that might have been entered into the cylinder above the lower member.
