a. Thisinvent on relates to paper perforating devices and particularly to devlces for perforating letters, bills, documents, and any ingand formin loose sheets printed or. written or the like, ready for filing.

The main ob ect of the invention is to provide an improved device for forming two or more perforations in sheets of paper or the like, and another object is to provide improved means for positioning the sheets to be perforated The means I prefer to employ for accomplishing the above-named objects, together. with other novel and advantageous features a modification, and

drawings. 1

As illustrated in the drawings, my improved paper perforating device embodies aase portion indicated by the numeral 1, and which base portion is wider at the rear than at the front and has a Quality of upright portions 2 at the rear, in this instance two,

but any desired and practicable number may be used according to the number of perfo-.

rations desired. Each of the said upright portions is provided with a vertical I in which is mounted a vertically-movable round and the en punch 4, the bod of which isreferably for punching oles may be of any desired shape. A hole registering with the unch is formed in a member neath sue die for said punch 4.

There is a lever\6 provided with a plural ore or hearing. 3.

branches 7 ofthe lever 6 are pivoted by means of pins 9, to the upper parts 10 of the upright portions 2, said ortions being" narrowed at these parts to t the's lots 11' in the branches 7 of the lever 6. ,The 'holes 12 inthe said portions 2 are made larger than the pins so as to provide for the endwise movement of the lever when it is pushed down to effect the punching or perforating. The punches 4 are pivotally connected to the lever branches 7 by pins 13, and there are

spring pockets

14 and 15 in the upright portions 2 and' the lever branches. 7 .respec- A tively, and there are springs 16 held in said pockets and coiled around the punches to normally hold the lever 6 and punches 4 in their retracted position. The upper ends of the punches 4 preferably bear against the upper faces of the pockets 15 so that eat force may be exerted on the lever (twitout springing or breaking the pins 13.

It is very advantageous to provide special means to position the sheets of the same are being perforate and the means I prefer to emplo for. this purpose are illustrated particular y in Figs. 1, 2 and 3 of the drawings.

The base portion of the device is provided with a channel or groove 18, and in said groove is a gage bar 19, preferably with a gaging portion 20, and it may also be notched on the side edges as at 21. In order to hold of the said bar, and in this form of the invenaper .when

tion the die plate 5 extendsforward far enough to cover the groove 18and a portion of the gage bar 19 therein. A screw such as 23 may be placed in the forward part of the plate 5 and by'meansof said screw the plate can be brought to bear on the gage bar to different degrees so that said bar is held by friction of the several parts after it has as the plate 5 which forms the" ity of branches 7, in this'insta-nce two in number, to corres 0nd with the number of punches 4, and t ere is a knob 8 onrthe been moved to any desired position alon saidgroove. There is a trigger 24-pivot on a boss 25 on the side of the rtion l 1, and thereis a-detent portion of said trigger which is preferably pointed so as to engage with the notches 21 when pressed toward the same by means of the spring 26. If it is desired to perforate standard size sheets, thenotches and detent may be used. The operation of using the above-described gage bar for gaging or positioning the paper to be perforate is-to set the gaging portion 20 by pushing'it' to the proper position, and a then to locate the sheets of paper by placing them with their right hand edges against the said gaging portion 20. The knob 8 is then pressed down and the perforating of the sheets is effected. When the spring pressed trigger 24 is used, it automatically moves into the proper notch when the same is moved opposite to it on moving the bar 19.

Figs. Land 5 illustrate a modified form of gage bar and the holding means therefor. In this construction the gage bar 19 is beveled at 28 on each side throughout its length and is held in position by the front edge of the plate 5 and the rear edge of the bar 29 which'are beveled to conform to the edges 28. Screws 30 are provided to secure the bar or strip 29 in place and to vary the friction of the same on the adjacent edge of the gage bar 19 so that said bar can slide with greater or less facility as desired. A spring plunger 31 is provided which is adapted to engage with the notches 21 in the side edges of the gage bar 19. a

Tn the form of the gage bar shown in Fig. 6, two springs 32 are provided to secure sufiicient friction on the gage bar 19 but otherwise the construction is similar to that in Figs. 4: and 5 except that the bar 29 and the spring plunger 31 are omitted and the channel 18 for the gage bar 19 is arranged to allow some play or looseness and the necessary resistance to hold it in its set positions is obtained from the said springs 32.

Fig. 7 illustrates another mode of giving frictional resistance to the gage bar. Tn this form the gage bar 19 is curved downwardly as at 19 and the depth of the channel 18 is such that the plate 5 when secured in place exerts pressure on the bar 19 to slightly compress the portion 19 thus giving a stated amount of friction to retain said bar in the desired positions. The bar may also be curved at the

parts

19 and 19 to give more working length to the bar 19 with the same frictional effect.
