PHILIP II. YAVMAN, OF ROCHESTER, NEW YORK, ASSIGNOR TO THE OFFICE SPECIALTY MANUFACTURING COMPANY, OF NEY YORK.
PUNCH.
SPECIFICATION forming part of Letters Patent No. 444,891, dated January 20, 1891.V
Application tiled May 20, 1890 Serial No. 352,509. (No model.)
To all whom t may concern:
Be it known that I, PHiLiP H. YAWMAN, of Rochester, in the county of Monroe and State of New York, have invented certain Improvements in Paper-Puuches, of which the following is a specification.
This invention relates more particularly to a punch designed to produce two or more holes or perforations simultaneously in a sheet or a series of sheets and in definite relation to the edge of the sheet. It is intended more particularly for punching letter-sheets and other papers intended for application to the well-known Shannon letter-tiles and similar files in which there are two tiling arches or wires to receive the sheets.
The special aims of the present improve` ment are to simplify the construction, reduce the cost of manufacture, and adapt the device for punching through a large number of sheets at one time.
In the accompanying drawings, Figure l is a perspective view of the improved punch. Fig. 2 is a front elevation of the same, one side being shown in vertical section. Fig. 3 isa vertical cross-section on the line :o a; of
Referring to the drawings, A represents a flatrectangularbasecastcompletein one piece, with two standards a on its top, and with a cavity or chamber of? in its underside. This bottom chamber, designed to receive and retain the punchings, is closed by a removable bottom plate a3, arranged to slide edgewise between the undercut shoulders or lips at, so that although held firmly in place it may be readily withrawn to discharge the contents of the chamber. Each of the standards a a is arrangedto overhang the base-plate at the forward end, so that the edges of the sheet to be punched maybe introduced beneath them, and in each of these overhanging ends is mounted a vertically-sliding solid punch B, the lower end of whichis arranged to descend through a hole b in the base-plate.
C represents a flat steel plate secured to the upper face of the bed-plate by a screw c or equivalent fastening, and provided with holes or dies c', registering with the holes b and adapted to co-operate with the punches in producing the required perforationsin the sheets. The plate C is projected at one end beyond the base and turned upward, as shown at c2, to serve as a gage or stop against which to rest the edge of the paper in order to insure the formation of the holes at the exact point required in the sheet.
Each of the punches is connected at its upper end by a horizontal pin CZ to the lower end of a yoke D, which partly encircles a 6o horizontal bar or shaft E, provided with an operating-handle e, and sustained at its two ends by eccentrically-located screws e', passing through the standards d a', so that by turning the shaft to and fro it causes the yokes to raise or lower the two punches simultaneously. The shaft E, which is in effect an eccentric, is commonly made of abar of round steel, its ends being grooved circumferentially to receive the yokes D. The yokes are 7o punched from sheet metal with a slot or opening in one side to admit of their being slipped over the shaft. After being thus applied they are slightly closed or compressed to prevent their escape. In place of the plate C, any other suit-able gage may be employed to determine the position of the sheet. The details may be otherwise modified, as the skill or taste of the mechanic may suggest, provided no material So departure is made from the construction and mode of operation herein described.
While I have illustrated and in most cases propose to use the two punches, it is mani fest that where it is required to produce a single hole one of the punches and its guide may be omitted without in any manner affecting the construction or operation of the remaining parts. My invention therefore. contemplates single as well as double punches 9o guided and actuated by the devices shown.
Having thus described my invention, what I claim isl. The duplex paper-punch consisting of the base-plate, its standards, the sliding punches in said standards, the eccentric-shaf t sustained by the standards, and the yokes or links connecting the two punches with the shaft.
2. In a paperpunch, the combination of a roo baseplate and a rigid standard overhanging the same and integral therewith, a punch chamber, the eccentric-shaft,v the links con- I5 nected thereto, the punch connected to the links and guided in the standards, and Jehe gege-plate fixed to the bed-plate and provided with openings through which the punches act to deliver the punchin gs into the base-cham- 2o ber.
In testimony whereof I hereunto set my hand this 2d day of May, 1890, in the presence of two attesting Witnesses.
PHILIP H. YAWMAN.
