US3658263A — Chopping and screening machine for candy particle…

Claim 1

Independent Claim 215 words

For reducing material into small particles, a machine characterized by a non-clogging, counter-rotating drive, said machine being of the type including a rotating screen cage having a longitudinal axis of rotation, means including a shaft counter-rotating within the cage to reduce material to small particles, means at one end of said longitudinal axis to introduce material into the cage, means at the other end to support the cage for rotation on said axis, and means at said other end to support the shaft for counterrotation on said axis, characterized in that the cage has an opposite end and has thereat hollow tubular support and drive means, and the shaft extends therethrough and therebeyond to shaft support and drive means, and the outer diameter of the shaft, so extending through the hollow tubular drive means, is less than the inner diameter thereof, whereby to provide a ventilation space, and the shaft has, immediately inward of said tubular drive means at said cage end, fan means to provide air inflow through such space, whereby the inflow of air through into the cage, at its end opposite to that at which material is introduced, prevents small particles of material from passing from the cage through the tubular drive means and clogging the drives of the cage and shaft.

Claim 2

Dependent Claim 215 words

For reducing material into small particles, a machine characterized by a non-clogging, counter-rotating drive, said machine being of the type including a rotating screen cage having a longitudinal axis of rotation, means including a shaft counter-rotating within the cage to reduce material to small particles, means at one end of said longitudinal axis to introduce material into the cage, means at the other end to support the cage for rotation on said axis, and means at said other end to support the shaft for counterrotation on said axis, characterized in that the cage has an opposite end and has thereat hollow tubular support and drive means, and the shaft extends therethrough and therebeyond to shaft support and drive means, and the outer diameter of the shaft, so extending through the hollow tubular drive means, is less than the inner diameter thereof, whereby to provide a ventilation space, and the shaft has, immediately inward of said tubular drive means at said cage end, fan means to provide air inflow through such space, whereby the inflow of air through into the cage, at its end opposite to that at which material is introduced, prevents small particles of material from passing from the cage through the tubular drive means and clogging the drives of the cage and shaft.

Claim 3

Dependent Claim 190 words

A chopping and screening machine, comprising a frame, a cage mounted thereon for rotation about a longitudinal, somewhat downward sloping axis, and having a cage inlet at an end corresponding with the upper end of said axis, a circumferential cage surface including screen-like perforations, longitudinally extending lifter means projecting inwardly from said surface, means to rotate the cage about the axis, an imperforate upper housing spacedly surrounding the upper part of the cage, and lower housing and discharge means extending downwardly therefrom, together with a cutter shaft extending substantially axially within the cage and having cutter blades extending radially outward and terminating short of the inward projecting lifter means, and means to rotate the cutter shaft at a substantially higher angular speed than that of the cage and in the opposite sense of rotation, the blades being arranged in a spaced progression along said shaft which progression is interrupted intermediate its ends by an unbladed shaft portion whose length substantially exceeds the inter-blade spacing of said progression, whereby to permit particles small enough to pass through the cage surface to be screened out withOut being subject to further cutting action.

Claim 4

Dependent Claim 190 words

A chopping and screening machine, comprising a frame, a cage mounted thereon for rotation about a longitudinal, somewhat downward sloping axis, and having a cage inlet at an end corresponding with the upper end of said axis, a circumferential cage surface including screen-like perforations, longitudinally extending lifter means projecting inwardly from said surface, means to rotate the cage about the axis, an imperforate upper housing spacedly surrounding the upper part of the cage, and lower housing and discharge means extending downwardly therefrom, together with a cutter shaft extending substantially axially within the cage and having cutter blades extending radially outward and terminating short of the inward projecting lifter means, and means to rotate the cutter shaft at a substantially higher angular speed than that of the cage and in the opposite sense of rotation, the blades being arranged in a spaced progression along said shaft which progression is interrupted intermediate its ends by an unbladed shaft portion whose length substantially exceeds the inter-blade spacing of said progression, whereby to permit particles small enough to pass through the cage surface to be screened out withOut being subject to further cutting action.
