Device for transferring particulate material

Claim 3

An apparatus according to claim 1, wherein said guiding means includes a chute mounted pivotably on said hopper.

Claim 4

An apparatus according to claim 2, wherein said closing means includes a cover mounted pivotably on the hopper.

Claim 5

An apparatus according to claim 3, further including means for resiliently pivoting said chute from the interior of the hopper to the exterior position for receiving the refill container in response to said cover being pivoted from the position closing the hopper to the position opening the hopper.

Claim 6

An apparatus according to claim 4, further including means, mounted on the surface of said chute in engagement with said refill container, for perforating a portion of the refill container to permit the particles to be discharged therefrom into said chute so as to be guided into the hopper.

Claim 7

An apparatus according to claim 4, further including a member mounted on the surface of said chute in engagement with the refill container, said member having an aperture for receiving the open end of the refill container in sealing engagement.

Claim 8

An electrophotographic printing machine of the type having a toner dispenser for furnishing toner particles to the development system with a refill container supplying additional toner particles to the open ended hopper of the toner dispenser, wherein the improvement includes: means for closing the open end of the hopper; and means for guiding toner particles from said refill container into said closing means closes the open end of the hopper and moving, in response to said closing means being moved to open the open end of the hopper, to an exterior position for receiving the refill container with the surface of said guiding means having a surface in engagement with the refill container and the surface being inclined to the horizontal so that the refill container does not have to be completely inverted when discharging toner particles into the hopper.

Claim 9

An electrophotographic printing machine of the type having a toner dispenser for furnishing toner particles to the development system with a refill container supplying additional toner particles to the open ended hopper of the toner dispenser, wherein the improvement includes: means for closing the open end of the hopper; and means for guiding toner particles from said refill container into said closing means closes the open end of the hopper and moving, in response to said closing means being moved to open the open end of the hopper, to an exterior position for receiving the refill container with the surface of said guiding means having a surface in engagement with the refill container and the surface being inclined to the horizontal so that the refill container does not have to be completely inverted when discharging toner particles into the hopper.

Claim 10

A printing machine according to claim 7, wherein said guiding means includes a chute mounted pivotably on said hopper.

Claim 11

A printing machine according to claim 8, wherein said closing means includes a cover mounted pivotably on the hopper.

Claim 12

A printing machine according to claim 9, further including means for resiliently pivoting said chute from the interior of the hopper to the exterior position for receiving the refill container in response to said cover being pivoted from the position closing the hopper to the position opening the hopper.

Claim 13

A printing machine according to claim 10, further including means, mounted on the surface of said chute in engagement with said refill container, for perforating a portion of the refill container to permit the toner particles to be discharged therefrom into said chute so as to be guided into the hopper of the toner dispsenser.

Claim 14

A printing machine according to claim 10, further including a member mounted on the surface of said chute in engagement with the refill container, said member having an aperture for receiving the open end of the refill container in sealing engagement.
