Abstract: A dirt collecting system for a vacuum cleaner includes a dirt cup formed with a first dirt collecting chamber and a second dirt collecting chamber separated by an apertured wall. An inlet opening is formed in the dirt cup and communicates with the first dirt collecting chamber for inputting a stream of dirt laden air into the first dirt collecting chamber. An exhaust opening is formed in the second dirt collecting chamber for allowing the filtered air stream to exit the dirt cup. The aperture wall includes a pre-filter for filtering coarse particles from a stream of dirt laden and depositing the coarse particles in the first dirt collecting chamber. A filter member is positioned within the second dirt collecting chamber and communicates with the exhaust port. The filter element filters fine particles from the air stream and deposits the fine particles within the second dirt collecting chamber.

Abstract: A bag housing assembly for a vacuum cleaner includes a rear bag housing which forms a bag cavity and a bag door which releasably attaches to the rear bag housing for enclosing the bag cavity. One of the rear bag housing and bag door is formed of a semi-rigid flexible fabric material which is permeable to air and which is sufficiently rigid to retain a molded shape. The flexible fabric material is attached to a rigid frame member which allows the bag door to releasably attach to the rear bag housing.

Abstract: A cyclonic dirt cup assembly for a vacuum cleaner has a generally conical truncated cone positioned within a dirt cup of the vacuum cleaner. The dirt cup has a wall formed with an air inlet opening for receiving a stream of dirt-laden air within the dirt cup. The cone is pivotally connected to a frame member which is removably mounted within the dirt cup. A baffle extends outwardly from a wall of the cone and is positioned adjacent the air inlet opening of the dirt cup for directing the stream of dirt-laden air in a cyclonic manner. The baffle includes a top wall, a side wall and a bottom wall. The baffle walls, the wall of the dirt cup and a wall of the cone form an air directing compartment which receives the dirt-laden air input through the inlet opening.

Abstract: A power assisted upright cleaner is provided with resilient spring cushioning for a hand grip driven actuating means that initiates power assist for the cleaner.

Abstract: A cleaner suction nozzle is provided in which provisions are made for a nozzle height elevation arrangement and a hose conversion valve arrangement. The hose conversion valve arrangement works in conjunction with the nozzle height elevation arrangement so that the suction nozzle can be elevated from the floor to disengage the cleaner agitator and then hose conversion of the cleaner can occur almost simultaneously.

Abstract: A manually operated release mechanism includes a spring actuated latch mechanism for latching a cash drawer within an enclosure upon movement of the cash drawer to a closed position. A rod member rotatably mounted adjacent the latch mechanism extends to a position adjacent the front edge of the enclosure. A drive member located adjacent the front edge of the enclosure has two cam surfaces, one of which is positioned adjacent one end of the rod member. When the cash drawer is in the closed position, a key actuated locking assembly on the cash drawer moves the drive member to an actuated position which engages and rocks the rod member to a position releasing the latching mechanism from engagement with the cash drawer. A depending tab portion of the cash drawer engages and slides the drive member to a home position upon opening of the drawer. The locking member disables the cash drawer from being operated by a solenoid mounted within the enclosure structure when moved to a locking position.

Abstract: A display device comprising a transparent substrate bonded to a portion of a printed circuit board forming the display envelope, the circuit board including a plurality of electrical conductors. A first portion of the electrical conductors has one end forming the cathode electrodes of the display and its other ends connected to electrical control elements mounted on the circuit board adjacent the display envelope. Anode electrodes of the display are mounted on the substrate and are connected to a second portion of the electrical conductors by metal connectors located within the display envelope. The second portion of the electrical conductors are also connected to the electrical control elements which control the operation of the display.

Abstract: A single drive mechanism providing selective feeding of at least two printing media and independent bi-directional movement of the media in the operation of a single print station. The drive mechanism including a platen member is movable to allow the two printing media to be positioned in the print station for a printing operation. The platen member is rotated in opposite directions to feed the two printing media to a printing position.

Abstract: A feed mechanism for moving a record member into a printing position in which a single control solenoid is energized to enable a pair of drive rollers to move a multi-form record member from a holding position to a printing position. Operation of the solenoid further moves a platen member into engagement with the record member which is spring urged to enable the platen to apply a force on the record member. The force on the platen is selected to compensate for the thickness of the record member allowing a dot matrix printer to print satisfactorily on record members of varying thicknesses. The drive rollers are normally positioned to locate a record member in a validating printing position. Spring means are associated with the drive rollers to engage and hold the record member in a printing position during the operation of the solenoid.

Abstract: The action of a rotatable cam assembly positions a plurality of type racks, enables printing and indexes paper prior to restoring the type racks to the home position. Teeth on the cam assembly engage teeth on the type racks for positioning thereof and an extended tooth on the cam assembly causes impact of the racks against a platen which is caused to be rotated by movement of the cam assembly to index the paper to the next print line.
