Abstract

A material chipping machine suitably employed for chipping ice blocks comprising base support means; material supporting and chipping means fixedly mounted on said base support means; a rotary drum member rotationally received in said material supporting and chipping means for rotational movement relative to said material supporting and chipping means; an arcuate material guiding and holddown conduit integrally formed with said drum member for rotational movement together with the latter; a hopper removably received in said drum member; and a handle connected to said arcuate material guiding and holddown conduit.

Claims

1. A material working machine comprising base support means;

stationary material supporting and chipping means fixedly mounted on said base support means and including a material support table having upper and lower surfaces, an integral blade mounting portion formed on said material support table and having an inclined face, said material support table having a slot therein and a material working blade adjustably secured to said inclined face of said blade mounting portion and extending through said slot with its edge projecting above the upper surface of said material support table;

a rotary cylindrical drum member mounted on said material for rotational movement relative to the latter and including an integral center sleeve portion having a lateral projection extending from one side thereof and means defining a hopper receiving opening on the side of said sleeve portion opposite to said lateral projection;

an arcuate material guiding and holddown conduit defining member integrally formed with said cylindrical drum member and extending along the inner surface of said drum member a substantial distance of the inner periphery thereof for rotational movement in unison with the latter, said conduit defining member being shaped to define with the upper surface of said material supporting table a conduit having its largest cross-sectional area at one end and its smallest crosssectional area at its other end;

a material feed hopper removably received in said opening of the rotary drum member for feeding material to be chipped to the conduit defined by said arcuate material guiding and holddown conduit defining member; and

an operating handle means fixedly connected to said rotary drum member and having a notch at one end for snugly engaging said lateral projection of said sleeve portion of said drum member whereby as the handle is turned said rotary drum, arcuate guiding and holddown conduit defining member and said hopper may be rotated in the direction in which the handle is rotated.

2. A material working machine as set forth in claim 1 in which said base support means includes a pedestal having an upper portion of circular cross section, a lower portion consisting of three equally spaced legs integrally formed with said upper portion, said legs being radially outwardly spaced from the lower end of said upper portion, suction cups secured to said legs for attachment to a support bed and a horseshoe shaped support plate fixed relative to said upper portion of said pedestal and including means adapted for threaded connection to said stationarY material supporting and chipping means.

3. A material working machine as set forth in claim 2 in which said stationary material supporting and chipping means comprises a substantially hollow frustoconical member including open ended upper and lower chambers said material support and working table separating said chambers, said upper chamber accommodating said rotary drum member and arcuate material guiding and holddown conduit defining member therein and said lower chamber accommodating said blade mounting portion, said blade, said horseshoe shaped support plate and a portion of said upper portion of said pedestal therein.

4. A material working machine as set forth in claim 1 in which said material support and working table is further provided with a central boss having an internally threaded central bore therein and a counter bore surrounding said internally threaded central bore, an inner annular boss radially spaced from said central boss and an outermost annular boss radially spaced from said inner annular boss, said central and inner and outermost annular bosses being integral with extensions from the inner surface of said material support and working table.

5. A material working machine as set forth in claim 4 in which said central and inner annular bosses have lower ends abutting against said horseshoe shaped support plate and means connecting said outermost annular boss with said horseshoe shaped support plate.

6. A material working machine as set forth in claim 4 and a vertical shaft having a threaded end in threaded engagement with and projecting beyond said internally threaded central bore in said central boss and a nut engaged in said threaded end and accommodated in said counter bore.

7. A material working machine as set forth in claim 1 in which the means defining said hopper receiving opening of said rotary drum member has a polygonal configuration and said hopper includes a constricted lower portion having a mating polygonal configuration.

8. A material working machine as set forth in claim 1 in which said material guiding and holddown conduit defining member has a substantially constant width throughout its length.

9. A material working machine as set forth in claim 1 in which said handle includes an L-shaped shank having a vertical section and a horizontal section, and means connecting said horizontal section with said material guiding and holddown conduit defining member whereby as said handle is turned, said rotary drum member and said arcuate material guiding and holddown conduit defining member are rotated in the direction in which the handle is turned.

10. A material working machine as set forth in claim 1 in which said material comprises small size ice blocks which have been formed in a freezing tray of a domestic refrigerator and are of substantially uniform shape and size.

11. A material working machine as set forth in claim 1 in which said material comprises vegetables.

12. A material working machine as set forth in claim 1 in which said material comprises fruits.
