Abstract

This illustrated paper or card feeder device is designed to rotate constantly, with clearance between the device and a paper bed. Paper may be driven under the device and allowed to rest there until feeding s initiated, at which time the paper is driven out from under it. The shaft is driven constantly. Affixed to the shaft is a hub containing pins that extend through flexible fingers if a paper driving wheel.

Paper Driver

This illustrated paper or card feeder device is designed to rotate constantly, with clearance between the device and a paper bed. Paper may be driven under the device and allowed to rest there until feeding s initiated, at which time the paper is driven out from under it. The shaft is driven constantly. Affixed to the shaft is a hub containing pins that extend through flexible fingers if a paper driving wheel.

Four of the pins straddle the two lugs on the flange of the spindle, limiting the relative motion between the pins and lugs. hen a braking action is applied to the brake drum on the spindle, a slowing down of the spindle and attached driving wheel is affected, causing it to move in a relative direction counter to the rotational direction of the pins.

This relative motion forces the flexible fingers of the driving wheel over the pins, causing them to move outward, creating an interference between the flexible fingers of the driving wheel and the paper bed. This interference will cause the paper to move. An idler roller may be used in the paper bed opposite the driving wheel and tangent to the surface of the paper bed. If an idler wheel, not shown, is skewed it will tend to register the edge of the paper against some alignment surface.

Driving force can be adjusted through the shape and size of the flexible fingers, hardness and surface characteristics, and the amount of interference between the flexible fingers of the driving wheel (in their ext...
