SPECIFICATION forming part of Letters Patent No. 436,048, dated September 9, 1890.

7 Application filed June 17,1890. Serial No. 355,733. (No model.)

- small, cheap, durable, and powerful punch or perforator; and to this end my invention consists in the features of construction and combinations of devices hereinafter more fully described, and particularly pointed out 1n the appended claims.

In the accompanying drawings, Figure l is a plan view of a punch or perforator embodying my improvements, the upper plate and handle being turned back. Fig. 2 is an edge view of the same and showing also in dotted lines the relation of the parts during the perforating or punching operation. Fig. 3 1s a top view of the combined handle and upper die-plate. Fig. 4: is a similar view of the lower die-plate. Fig. 5 is a verticatsection taken at the line a: a: of Fig. 1.

In the several views the same part will be found designated by the same numeral of reference.

1 represents a base-plate having perforations 2, by which the contrivance may be screwed upon a board or tablet 2. Formed integral with the base-plate at the front and flaring outwardly are two ears or lugs 4, each of which is provided with a punching-die 5. At each end of the base-plate is formed an upright 6, having a horizontal perforation 7 and a vertical wall or face 8. The perforations are directly opposite each other and the vertical walls are arranged in line.

9 designates a cross-bar of a length sufficient to just fit between the inner faces of the uprights 6, and formed at each end with a threaded hole 10 to receive the threaded end of a screw 11, which is provided with a plain cylindrical portion 12. The plain portions 12 of the screws are arranged to occupy the plain perforations 7 in the uprights and form journals for the cross-bar. Formed integral with the cross-bar is a forwardly-extending handle 14 and two arms 15, each provided with a perforation 16. The arms extend laterally beyond the ends of the crossbar and forwardly, so that the perforations 16 register with the punching-dies in the base-plate. The punching-dies are provided each with a rubber sleeve 17 to act as a stripper.

In the operation of the contrivance the handle and the arms 15 are raised, and the letter-sheet or bill or other paper is passed over the tops of the dies until its edge abuts against the two vertical walls 8 of the uprights. The handle and the arms are then turned down to the dotted-line position shown at Fig. 2, and the studs, coacting with the holes 16, caused to punch or cut out two circular disks from the paper. The handle and the arms are then raised and the paper removed and placed upon the wires of a letter or bill file, if desired. The contrivance is adapted to be fastened to the tail end of a letter or bill file tablet, and when thus applied the handle portion may be swungback, as shown at Fig. 2 in full lines, to bear upon the free ends 'of the sheets and hold them down in position.

By the oblique or flaring arrangement of the lugs or cars 4 and the arms 15 I am enabled to set the punching devices farther apart than would be possible if the arms were arranged at right angles to the cross-bar. The vertical walls or faces 8 of the uprights 6 serve as stops or gages for the top edges of the sheets of paper to be punched, and hence all of the sheets may be perforated at the same distance from said edge and be arranged evenly on the upright wires or tubes of a file or binder. By reason of the capacity of the handle and arms to be turned back through almost one hundred and eighty degrees the insertion and gaging of the sheets to be perforated may be most conveniently accomplished. As the handle is made comparatively long and the cutting or punching performed quite close to the fulcrum or center of movement of the handle or lever, aconchanging the relationship or altering the alignment between the perforations l6 and the studs or dies 5, which alignment, it will be understood, must be always carefully preserved to insure proper working of the contrivance. There may of course be as many studs or dies and oomplemental perforations as desired, and without departing from my invention the dies may be upon the arms 15 and the perforations in the base-plate, though I prefer the plan illustrated.

WVhat I claim as new, and desire to secure by Letters Patent, is-

1. In a perforator, thecoxnbination of a base-plate having two uprights, a cross-bar arranged between and pivoted to said uprights, an operating-handle, and diecarrying arms, the handle and the arms being made integral with said cross-bar, as set forth.

2. The combination, with a base-plate having studs or dies and two uprights provided with journal-hearings, of across-bar threaded at each end and arranged between said uprights, the screws engaging with the crossbar and having plain journal-like portions resting in the bearings in the uprights, 'and the perforated arms and operating-handle made integral with the cross-bar, as set forth.

3. The combination, with a base-plate having flaring ears or lugs provided with studs or dies and two uprights provided with journal-bearings, of a lever arranged between and pivoted to said uprights and having obliquely-arranged arms provided with holes to co-operate with the studs or dies, as set forth.

Signed at New York city, in the county of New York and State of New York, this 14th day of June, A. D. 1890.
