The invention relates to a dispensing cartridge adapted to discharge material therefrom to a receiving member during a dispensing operation. The cartridge includes an inner tubular member with an inner port therein. The cartridge also includes an outer tubular member with an inner surface, an outer surface, and an outer port therein. The inner tubular member is mounted rotatably within the outer member and is in sliding contact therewith. A cover is coupled to the inner tubular member and is adapted to rotate the inner tubular member in response to movement of the cover from a first position, wherein the inner port and the outer port are aligned with one another to define an exit aperture for discharging material from the cartridge to the receiving member, to a second position, wherein the inner port and the outer port are misaligned from one another to define a closed position preventing discharge of material from the cartridge. The cartridge further includes a receiver for receiving material contained in the cartridge during a dispensing operation and a housing having inner and outer tubular members. The inner member is concentrically mounted to and is in sliding contact within the outer member for either clockwise or anti-clockwise rotation therewith. Each member has a port. The ports are arranged to align with one another when the inner member is rotated in a first direction. The ports further are arranged to misalign with one another when the inner member is rotated in an opposed direction, to define a closed off position desirable prior to removal of the cartridge from the receiver.

Dispensing cartridge

The invention relates to a dispensing cartridge adapted to discharge material to a receiving member during a dispensing operation. The dispensing cartridge comprises an outer member which defines a chamber and an outer port therein and an inner member. The inner member defines a chamber for storing the material and an inner port therein. The inner member is located within the chamber of the outer member with the inner port thereof being aligned with the outer port of the outer member during the dispensing operation. The inner member is adapted to change shape during the dispensing operation to facilitate the dispensing of material from the chamber of the inner member, through the inner and outer port, and to the receiving member.

Dispensing cartridge having a resilient follower

An apparatus for dispensing material in which a housing is adapted to store a supply of material therein. The housing has an exit aperture for discharging the material therefrom. The exit aperture is sealed by inner and outer seals. The outer seal prevents access to the inner seal when the exit aperture is in a closed position. When the housing is moved from the closed position to an open position, the inner seal moves over the outer seal to an open position wherein the exit aperture is spaced from both the inner and outer seals so that material may be discharged therefrom.

Sealing arrangement for a toner dispensing cartridge

A sealing arrangement for a container in which an auger having vanes is disposed in the chamber thereof for moving particulate material stored therein. A threaded sealing member is adapted to engage the auger vanes so as to be driven along the container on rotation of the auger. The sealing member is mounted slidingly within the container but is restrained from rotating about the auger. On rotating the auger, in one direction, the sealing member moves along the auger to a storage position located beyond the auger vanes.

Sealing arrangement

An apparatus which seals a shaft mounted rotatably on a bearing member. At least two spaced apart annular flanges are mounted on the shaft. One of the flanges being is arranged to bear radially against the bearing member. An annular sealing member is mounted on the shaft between the two flanges in abutting relation with at least one of the flanges to form a radial seal with the bearing member.

Sealed bearing assembly

A sheet feeding apparatus for a copying machine includes two sheet trays and a frictional feeding device in a fixed location for top-feeding sheets from either one of the stacks. The trays are carried one above another by a tray carriage and are arranged for independent slideable withdrawal from the tray carriage towards the front of the machine. The tray carriage is mounted for vertical movements, and the upper tray is slideably mounted on a sub-frame for movements thereover in the sheet feed direction, i.e. across the machine, so that the top sheet in either one of the two trays may be brought into feeding engagement with the feeder device.

Sheet feeding apparatus

A sheet transport for a photocopier for reversing the direction of sheet travel has only an outer curved guide surface, and input, intermediate and output drive rolls spaced apart less than the length of a sheet. The disengageable output drive nip cooperates with an opposed guide surface and one or more retractable stops to achieve registration of the copy sheet with the image.
