Mechanical Motion Retarding Means

Retardation of the return motion of a card rest in a stacker is obtained by coupling an inertia element via a unidirectional coupling means to the 1 ad device.

Documents are delivered in a substantially vertical direction to the stacker 1 and build up in a stack against a plate card rest 3, which is urged against the stack by spring pressure. Plate 3 rides on a bed plate 5 including grooves 7, and is carried by a carriage 9 which has an extension fastened to plate 3. Carriage 9 rides on a rod 11, so that it can move to and fro as shown by the two-headed arrow. Carriage 9 is further guided and retained in its proper path by a roller 13 pivotally attached to the top of the carriage and riding in a stationary guide member or channel 15.

Mounted on another stationary support or plate 17 is a conventional "negator" or spring motor 19. The rim of negator or motor 19 is provided with a pulley-type surface, on which is wound a cable 21, the other end of which is connected through a small wire hook to carriage 9. Negator 19 is arranged in the usual fashion to provide a spring return force tending to rotate the negator in a counterclockwise direction, as viewed in the drawing. This force accordingly urges plate 3 toward the left to hold it against the stack of documents.

When the machine operator removes a portion or all of the stack of documents after the stacker has accumulated a stack of sufficient size, the spring motor 19 will rotate counterclockwise, thereby winding the ca...
