Abstract

An abrasion or rasp disk for use in a soap dispenser for abrading soap particles from a soap bar, the disk being provided with a plurality of curved radially extending recesses having abrading teeth struck from an edge thereof.

Claims

1. A rotatable rasp disk for use in connection with a soap dispenser which operates with bars of soap comprising:

a disk having projecting teeth thereon, the teeth provided along longitudinal edges of a plurality of arcuately curved recesses through the disk, the recesses comprising slots, said slots being curved in a radial direction and formed as segments of a circle having their centers circumferentially ahead of the slots in the direction of rotation of the disk, the slots having opposed end portions curving away from an intermediate portion in the direction of rotation, the teeth provided by the material of the disk projecting upwardly therefrom at an angle to the plane of the disk in the direction of rotation.

2. A rasp disk according to claim 1 wherein the center points of the circles of which the recesses are segments are arranged such that the inner ends of the recesses are substantially vertical to a shaft supporting the disk through the axis of the disk and outer ends of the recesses are substantially tangential to the outer periphery of the rasp disk.

3. A rasp disk according to claim 2 wherein the center points of the recesses are arranged on a base circle having a diameter of approximately half the diameter of the rasp disk, the base circle being concentric with the rasp disk.

4. The disk of claim 3 wherein at least two of the recesses are disposed on opposite sides of the disk from one another and are radially symmetric with one another and are disposed on the disk in substantially S-shaped relation.

5. The disk according to claim 4 wherein two alternating sets of recesses are provided, one of said sets having the inner ends of the recesses terminating adjacent the base circle.

6. The disk of claim 5 wherein the centers of curvatures of all the recesses are arranged on the base circle and are located approximately 45* circumferentially from one another.

7. The disk according to claim 6 wherein the teeth of the rasp disk are triangular shaped with projecting tips directed radially outwardly from a side edge of the recess in the direction of rotation of the disk.

8. The disk of claim 7 wherein the teeth are bent outwardly from the plane of the rasp disk greater than 45*.

9. A rasp disk for use in soap dispensers which comprises:

a disk, said disk having an axial opening therethrough, a plurality of recesses through said disk, said recesses lying between the opening and an outer periphery of the disk, said recesses curved in a radial direction and formed as segments of circles having their centers circumferentially ahead of the recess in the direction of rotation of the disk, the centers of the recesses lying on a base circle having a diameter approximately half the diameter of the disk, and teeth provided on a circumferential back side of each recess with regard to the direction of rotation, the teeth projecting at an angle from the plane of the disk towards the direction of rotation.

10. A disk according to claim 9 wherein two sets of alternating recesses are provided, one of said sets having an inner diameter end closely spaced to the central opening and an outer diameter end closely spaced to the periphery of the disk, the outer diameter end approaching the periphery substantially tangentially thereto, the other set of recesses having inner diameter ends terminating at the base circle.
