SHEET LIFTING AND COUNTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 500,379, dated June 27, 1893.

Application filed June 7.1892. Serial No. 435,880. (No model.)

To all whom it may concern: is rigidly attached to the platform A, and

This frame raised a small distance, it will bend on itself,

and the tip d will be under a loop. If new the rotary motion of the wire be reversed, as will be done by the spring H upon raising the foot from the treadle, the tip (Z will return to the initial position, and a second pressure on the treadle Will raise the corner of the second sheet and so on for the other sheets. The motion of the treadle and thus of the rolling Wire may be regulated by the skill of the attendant or by any mechanical means. The rotary motion of the Wire should preferably be about three quarters of a revolution in each direction. It will be seen that the sheets will be pushed aside seriat L'm, and if a device for removing the sheets be attached or a register K for counting the number of movements in one direction of the rolling Wire, the said sheets may be removed singly or counted.

\Vhile I have described the device as used upon pads or piles of sheets of paper; it is equally efiicient in raising the corners of or counting a number of superimposed lengths of thin materials such as calico, linen, and the like.

The device With a register may be depended upon to count Without error piles of bank notes, ballots, tickets, &c.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. The combination of a rod or Wire yieldingly mounted in a frame, and having a bent arm with an adhesive tip; and means for turning said rod or wire about its axis through any desired arc alternately in either direction, substantially as and for the purposes described.

2. The combination with a suitable platform, of a rolling rod or Wire yieldingly mounted thereon, the said rod or Wire havingabent. arm, and an adhesive tip to said arm; and means for turning said rod or Wire about its axis through any desired arc, alternately in either direction, substantially as and for the purposes described.

3. Adevice for producing folds in and counting leaves, comprising a rolling rod or Wire having a bent arm, an adhesive tip on said arm, mechanism for turning said rod or wire about its own axis through any desired arc, alternately in either direction; and a counting device operated by said mechanism, substantially as and for the purposes described.

In testimony whereof I alfix my signature in presence of two Witnesses.
