, n PAPER-PERFORATNG DEVICE.

Application filed January 4, 1926, Serial No. 79,129. Renewed May 31, 1928.`

This invention relates to paper perforating devices and especially to devices of this class which embody single punches and means for supporting papers and in which the perforating movement is effected by a depressible knob above the rest of the device.

The main object of the invention is to provide improved means for positioning the papers to be perforated, and another object is to provide an improved base member having lever fulcrum construction which facilitates assembling cert-ain parts ofthe device.

The means I prefer to employ for accomplishing the above mentioned objects, vtogether with other advantageous featnresof my improved paper perforating device which will appear as the description progresses, are illustrated in thedrawing accompanying and forming part of this specification, and in Which- Figure lis a plan of my improved paper perforating device.

Fig. 2 is a side elevation of the same.

F ig. 3 is a detail plan ofthe gauge bar for the same, and

v Fig. 44' is a side elevation of said gauge bar.

Like characters of reference refer to like parts in all the figures of the drawing.

Referring to the drawing, kthe invention embodies a base member 1 Which is preferably Wider at the rear than at the front. There is an upright portion 2 near the rear and preferably at theright hand side of the base member `and ordinarily integral there with. The said portion 2 is provided With a bore or punch bearing 3 Which is preferably arranged verticallyand in Which is mounted the vertically movable punch 4, Which is preferably cylindrical for the greater part: of its length to fitthe bearing 3 and formed at its lower end into any desired shape so as to register with the perforation 50 formed yin the die plate 5 which plate is attached to the base member 1 by suitable means such as the rivets 51.

There is a lever 6 having a knob Sand a slot or fork 11 through which passes the fulcrum pin 9. The punch 4 is jointed .to the lever by means of the pin 13 and there is an additional bearing surface 15 direct-ly over the upper end of the punch 4 Which is rounded to conform to t-he same and great pressure can be brought to bear ont-he punch when perforating the papers, Without unduly straining the pin 13. p

. The uprighty portion 2 of thebase member 1 fits the fork or slot 11 of the lever 6 and it has a slot 12 in its front face O2 in which plate 5, and in said groove is a longitudinally movable gauge bar 19 which is provided with a transverse portion 20 substantially parallel to the punch and die axis. The die plateY 5 vmay bear yieldingly on the top part of the bar 19, but the bar itself is preferably formed' With inherently resilient bearing edges such' as 22, made by forming a slot or slit in the bar and forcing the halves of the bar apart'.v This construction is advantageously made in quantity production by shearing the portions 27 apart, spreading them and bringing them to the condition shown in Figs. 3 and .4, and when the gauge bar is pushed into the groove 18, the edges 22 bear against the side edges of the groove and hold the bar temporarily in any desired position lengthwise of the groove 18 so that the gaug-in, ,rVV portion is held at anydesired distance from' the punch 4.

For greater convenience in positioning the papers to be perforated, I Vprovide one ory more iiducial elements for use in con]unc tion With the gauge bar andv other members'. The said iiducial elements may be in the form of ribs or projections such as 35 and formed on the base member integral therewith or in the form of gradua-tions such as 36 lformed on a platesuch as the die plate 5. Suitable indicia such as 37 may be provided for either of said fducial elements.

There are various methods of utilizing the above described paper perforating device for perforating papers and especially for perforatin'g them for use vvithV pronged or tongued metallic paper fasteners. For eX- ample standard size sheets such as letter size, may be perforated one hole at atime by using the gauge bar v19 With the portion 2O set for therequi-red distance from the punch to the right or left hand edge, first punching a hole on the right hand side and then one onthe left or vice versa. Several sheets'can be held together and perforated at onetime if desired so as to save time.

Another method employs the fidueial ele1 ments or 36, and in this mode it is better to mark the middle point of the sheet as by doubling the same and marking by a slight crease or other mark and then setting the sheet by placing said mark or crease opposite the liducial mark ifor the size fastener indicated next to it and thus the holes will be spaced exactly right for the standard sized fastener indicated by such marking. By doubling the sheet and setting the edge of the doubled part to the liducial mark both holes in a sheet can be perforated in one operation. Either the ribs 35 or the graduations 35 may be employed in this method oi' perforating. The gauge bar 19 may be provided with graduations 3A and indicia lil, which graduations on heilig set even with the right hand edge of the die plate, allow the gauging portion 2O of the bar 19 to be set for peri'orating standard size sheets as indicated by the indicia 41.

The construction of the fulcrum slot 12 is very advantageous, as it allows the lever 6 and the parts attached thereto to be more rapidly assembled with the base member.

The fulcrum pin 9 is first assembled with the lever 6, through the holes 90 therefor and spanning the slot 11. The punch t` is then ut in the punch bearing 3, with the spring 16 1n the pocket 14 and surrounding the punch. The lever 6 is then put in place by slipping the pin 13 transversely into the end of the slot 12 and pushing it back so that the lever Cil slot 11 clasps the upper part of the portion 2 of the base member as seen in Fig. 1. The pin 13 is then driven into place through the lever and punch so that the parts are in the positions shown in Fig. 2. Y

lVhen it is desired to perforate three or more holes in sheets, the operations are substantially as follows To perforate three holes, Iii-st fold the sheet to locate the middle hole. Line the folded crease with the center mark 42 of the punch 4, the said mark `being on the front of the overhangingpart of the upright portion 2. Set the gauge bar 19 and perforate the middle hole tor all the sheets in the lot to be perforated. The locations of the remaining two holes in one sheet are obtained byvplacing the center of the middle hole in line with the marking for the desired spacing. The gauge bar 19 is then set forth perforating both the remaining holes in each sheet of the lot.

Four holes are perforated by iirst locatin and perforating the two middle holes, an then the outside holes are located by placing the center of one of the punched holes at the mark for the desired spacing of the holes. To perforate five holes in a sheet first locate and perforate the center hole, and then locate the remaining four holes in a similar manner as when perforating three holes.
