- IMPROVEMENT IN MECHANISMS FOR AUTOMATICALLY SELECTING AND PRESENTING STAPLES.

Specification forming part of Letters Patent No. 190,268, dated May 1, 1877; application filed April9, 1877.

To all whom it may concern:

Be it known that I, JAMES W. BIoKNELL, of Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in Mechanism forAutomatically Selecting and Presenting Staples, of which the fol lowing is a specification:

This invention relates to mechanism to automatically select and present staples to a proper driver to be driven. I

The invention is applicable as an attachment or as a co-operative part of a machine to unite paper-as pamphlets and books-or to unite leather with staples or in a blind-staple machine.

The invention consists incombining a device for automatically picking up the staples, with a receiver for thetstaples so picked up, the receiver retaining the staples all in one uniform position, ready to be removed therefrom to be driven.

Figure 1 represents a plan view of this invention Fig. 2, an end elevation thereof; and

' Fig. 3, forms of staples which this machine'is adapted to pick up and drive.

In book-stapling machines it is customary to form the staples singly from wires just before they are driven.

The addition to such a machine of the staple-forming parts increases its cost unnecessarlly.

One machine to make staples can be made to furnish staples for a large number of driv- Tugmachines.

In this my invention the staples are formed by a machine sp'ecially designed for the purpose, and of any desired shape, according to the use to which they are to be put. Such staples are placed in a hopper, in

a driver, to be driven into the materials to be united or to be provided with staples.

The hopper a, sustained upon a suitable part of the machine, is supplied with staples b of any desired-shape.

A bearing, 0, supports a shaft provided with up a staple (one or more) as the coil rotates,

and as it rotates such staple is carried laterally along to the heel 4, which moves with such relation to the receiver 9 as to enable the .ends of the staple held upon the last round of the coil to pass below the top surface of the receiver, and then the picking-up device, in its further rotation, withdraws its heel 4 from the staple, leaving it upon the receiver, down or along which it slides until arrested by a suitable stop, it, in practice made movable, or by a staple.

The staples may be liberated when the stop is withdrawn, and Ya suitable finger or slide may be made to detach the staples singly, and transfer them to a proper position to be driven by a driver, which may be located as at 13, and be operated in any usual 1. The combination, with a staple-receiver, v

of a picking-up device adapted to automatically pick up staples from a mass of staples, and present them upon the receiver, substantially as described.

In testimony whereof I have signed my name to this specification in the presence Of two subscribing witnesses.
