The plate 15 is For a full understanding of the inventionf provided with a plurality of perforations reference is to be had to the following deindicated conventionally at 23 and correv scription and accompanying drawings, inI spending in size and distance apart with 90 which 5 the perforating pins of the improved de- Figure 1 is aside elevation of the im-A vice, as hereafter explained.

Fig. 4 is an enlarged perrod 25. The shaft 12 is likewise provided spective view of one of the combined strip-I with av stop collar 26 for each of the guides per andguide plates. 24 and each provided with a set-screw 27 Corresponding and like parts are referred7 to enable the collar to be adjusted to any j .45 to in the following description and indidesired extent and likewise rigidly coupled 100 cated in all the views of the accompanying to the shaft. At its lower end each rod is Y drawings by the same reference characters. provided with a transverse head 28 from The improved device comprises a base or which the perforating pins 29 depend, the table 10 of any suitable material or any suitpins corresponding 1n size and distance able size, the table being formed( to correapart with the apertures 23 of the platen 105 spond to the size ofthe sheets to be perfoplate 15. Connected to the base 10 opposite rated. It is not desired, therefore, to limit each row of pins 29 is a guide plate 30 havthe size of the table or other parts. ing perforations corresponding to the pins Rising from the base 10 at the ends are 29 and through which the pins move when standards 11 in which a main driving shaftV the rod 25 is operated. The plate 30 thus 110 serves the two fold purpose of a guide for the pins and likewise as a stop-plate to prevent the paper or other article which is being perforated from being moved upwardly at the return stroke of the pins, as hereafter more fully explained.

Means are provided for actuating the rods 25, and an improved means for accomplishing this result is shown, and consists of a cam-wheel 31 mounted for rotation with the shaft 12 and provided with a cam-groove 32 in which a laterally extendingoifset 33 of the rod 25 operates. The guide 24 is provided with a longitudinal slot 34 through which the offset 33 extends and in which it moves vertically under the influence of the cam. By this simple arrangement it will be obvious that when the shaft 12 is rotated the cam 31 will, through the coaction of the offset 33 and the cam-grooves 32 impart a vibratory movement to the rods and cause the pins 29 to pass downwardly through the plate 30 and into the perforations of the platen plate 15, and punching apertures corresponding to the pins in any paper or other article which may be inserted between the plate 30 and the platen member 15. At the return stroke of the rods 25 the plate 30 will serve as a stop to prevent the paper or other article from being lifted from the table, as will be obvious, or to strip the paper from the pins.

Connected to the table 10 near one end is a gage-member 35 provided with an adjusting screw 36, while a similar gage 37 is located upon the table near the opposite end, and rendered adjustable by a clamp screw 38. The gage 35 extends transversely of the base 10, while the gage 37 extends longitudinally of the table. The gage plates thus serve as means for guiding and supporting the paper which is to be perforated, and may be readily adjusted to correspond to the size of the paper. As before stated, any required, number of the perforating devices may be employed, but generally three will be used, as shown. The cams 31 are each provided with a set-screw 39 so that the cams may be adjusted longitudinally of the shaft and thus coact with the stop collars 26 and their set-screws 27 to adjust the guides 24 longitudinally of the shaft when required. By this means all the different parts may be readily adjusted to cause them to operate in perfect unison.

'Ihe improved device may be constructed of any suitable material and of any suitable size to adapt it to the work required and may be adapted for use in banks, commercial houses, printing oflices, or other localities, but is designed more particularly in the use of printing houses for the purpose of perforating sheets which are afterward bound in books such as checks, drafts, blank receipts, or orders and the like, and is capable of general application as an efficient perforating machine.

Having thus described the invention what is claimed as new is 1. In a device of the class described, a table, a plate having a plurality of apertures and supported upon said table, a shaft, a tubular guide depending from said shaft, a rod slidable in said guide, a plurality of pins carried by said rod and corresponding in number to and adapted to enter the perforations of said plate, and means operative by said shaft for reciprocating said rod to cause said pins to enter said apertures.

2. In a device of the class described, a table, a plate having a plurality of apertures and supported upon said table, means for adjusting said plate, a shaft, a tubular guide depending from said shaft, means for adjusting said guide upon said shaft, a rod slidable in said guide, a plurality of pins carried by said rod and corresponding in` number to and adapted to enter the perforations of said plate, and means operative by said shaft for reciprocating said rod to cause said pins to enter said apertures.

3. In a device of the class described, a table, a plate having a plurality of apertures and supported upon said table, a guide supported upon said table and provided with apertures corresponding to the apertures of the plate, a shaft, a tubular guide depending from the shaft, a rod slidable in said guide, a plurality of pins carried by said rod and corresponding in number to and operating through the apertures of the guide and likewise corresponding to and adaptedv to enter the perforationsof said plate, and means operative by said shaft and reciprocating said rod to cause the pins to enter the apertures of said plate.

4. In a device of the class described, a table, a plate having a plurality of apertures and supported upon said table, a shaft, a tubular guide depending from said shaft and provided with a longitudinal guide slot, a rod slidablein said guide and provided with an offset extending through said guide slot, a plurality of pins carried by said rod and corresponding in number to and adapted to enter the perforations of said plate, and a cam device connected to said shaft and engaging said offset and operating to reciprocate said rod to cause said pins to enter said apertures.

5. In a device of the class described, a table, a member having a socket cavity and carried by said table, a plate slidable in said socket and provided with a plurality of apertures spaced apart, means for adjusting said perforated plate in said socket, a rod having a pluralityof pins corresponding in number to and adapted to enter the perforations of said plate, and means for reciproeating said rod and the pins carried thereby.

6. In a device of the class described, a table, a member having a socket cavity and carried by said table, a plate slidable in said socket and provided With a plurality of apertures spaced apart, means for adjusting said perforated plate in said socket, a guide supported upon said table and provided with perforations corresponding to the perforations of the plate, means for adjusting the guide, a rod having a plurality of pins corresponding in number to the apertures of the guide and of the plate and adapted to enter the perforations of said plate, and means for reciprocating said rod and the pins carried thereby.
