Abstract: An adjustable support structure for temporary sign displays formed from a vertically oriented rigid panel having a plurality of length and angle adjustable support arms. Each arm has a distal end thumb screw attachment to a T-nut on the sign. The arm is adjustably anchored to the panel by a bolt extending from the panel through a longitudinal oval slot in the arm to engage a wingnut. Additional hardware prevents loss of movable parts. Sign stiffening battens are tethered to the panel. A stiffening tray parallely spaced apart from the back of the panel further bears against and secures the support arms.

Abstract: A machine particularly adapted for dispensing light items packaged in symmetrical, frustum-shaped container. The items are propelled through a tubular cartridge and individually ejected by a flow of air generated by a blower under control of a toggling dual-gate mechanism at the dispensing end of the cartridge. The dual-gate mechanism of a removable magazine grouping a number of cartridges can be selectively addressed and activated by means of a solenoid-driven cross-bar assembly.

Abstract: A vending machine having a substitutable magazine formed to have a number of parallel vertically oriented tubular hoppers for queuing up goods to be dispensed. The magazine is supported on a rotatable platen. A user selects a tube where the desired good is located, rotates the platen so that the tube is in alignment with a dispensing station. Upon payment of the proper fee, the user energizes a solenoid which drives a single item dispensing rocking gate, dropping the item from the selected tube. A dual position pivoting rocker arm gates a single item while preventing subsequent item from falling through.
