Abstract: A dispenser for flexible sheet material having a reserve roll that automatically moves in the dispensing position when the dispensing roll is almost exhausted. The sides of reserve roll guide tracks are angled inwardly to engage the reserve roll spool at an off center point, so the spool is pushed downwardly into contact with a driving roller during rotation. The leading edge of the reserve roll towel engages the remaining portion of the almost exhausted dispensing roll and is moved therewith to be threaded through the dispensing mechanism. The perforating mechanism is assisted through the perforating stroke by a spring mechanism. The sensing roll is halted by a roll stop mechanism including a pivoted stop link and an anti-reverse pawl.

In this way, the scrap edge portion of the strip is permanently gripped between the nip of the rolls at all times, and at the same time the fan-like action of the blades is eliminated, since they are flush with the surface of the rolls.

Abstract: The cutting mechanism comprises a driving shaft and a driven shaft. A motor is connected to the driving shaft and rotates the driving shaft in a first direction. A gearing arrangement interconnects the driving and the driven shafts so that rotation of the driving shaft causes concomitant rotation of the driven shaft in a direction opposite to the first direction. Coacting cutting means are provided on the driving and the driven shafts for cutting material received therebetween. A motor is connected to the driven shaft and rotates the driven shaft in a direction opposite to the normal direction of rotation of the driven shaft to eliminate backlash between the coacting gears. Thus, the clearance between the cutting edges of the rotary cutting means is always constant and uniform.

The locating element is adjusted by means of an eccentric mounted on a pivot, the eccentric having a hexagonal head for adjustment purposes, and a clamping screw to fix the eccentric in position. The locating element may itself be provided with several abutment surfaces for varying the radial position of the blade. A resilient backing strip is inserted on the opposite side of the blade.

Abstract: Box capacitors are loaded onto an in-line track feeder with the capacitor leads extending downward between a pair of tracks. Vibration of the tracks moves the capacitors thereon so that the capacitor leads pass between the meshing teeth of a drive gear and an idler gear that is caused to turn by the former. The tracks are spaced from the gears to prevent damping of vibrations of the former. The leading edges of the teeth on the gears have a radius thereon for providing smooth feeding action of the capacitor leads between the gear teeth. The drive gear also has a chamfer on the top edges of the teeth thereof to reduce the possibility of jamming on components with bent leads. A disk is attached to the underside of the idler gear for cutting the component leads to a prescribed length as they pass between the disk and the drive gear. The ends of the teeth on the idler gear are truncated such that a cut lead is compressed into a valley between teeth on the drive gear to thereby straighten these leads.
