Patented May 28, 1935 e jUN T D'LS E ARTICLE on I Elmer L.- Kokanour, Fort Lauderdale, Fla. Application March 22, 1934, Serial No. 716,775 r 4 Claims. (01.164-98) I The present invention relates to an article of printers furniture which may be installed, one or more, on a part of a printing press that carries the impression sheet, for examplesuchas the 5 platen ofa job printing press, togsir'nultaneously print and punch, or to enable the use of'such'a press as a punching machine, which may readily I be accomplished, simply by omitting theprinting l0 manner.

' oftentimes job printing shops or small printingshops are required to turnout punched werk. Many of such shops are not equipped with punching machinery, hence have to efiect the punching Then, too, such shops often have orders for loose leaf work, requiring printing and punching; of many sheets of paper.-' Such shops not properly equipped. i'or punching 'areat disadvantages in turning out such work,-thusadding to the cost of "production of such class of printed and punched matter. I q j I The present invention has to do with a simple punch device which may be readily att'ached,*one V V of slightly different-form. r I

25' or more, to a part of a printing press whichcarries the impression sheet, such forinstance as the platen'of a job press, to'punch the impression sheet simultaneously with the printing operation. so object of the present invention'fis to provide a punch device which may be readily applied to any part of a platen of a printing press-for punching sheets of paper simultaneously with the printing impressions; '1 I Another object of the invention to provide a punch device readily applicable to a platen of a platen type'press', by slitting the tympan draw sheet to receive the toe of thedevice and having 'bailf;

' A further object'of the invention is 'to provide an article of printer's'fun iture applicable to the part of a printing press which carries the impresa punch device which'may'be"rea dilyapplied to any partof a platen; for punching holes in the impression sheet at desired placesin such sheet. The invention contemplates such a'device which punches the holes as the platen is moved against the printing-form the operation of the press.

a D ft to be clamped'against the platen by the above, other and 'further objects of the invention will be: readily understood from the following description, accompanyingdrawing, and appended claims' I F e The accompanying drawing illustrates various forms of punch devices-all embodying principles 5 ofathe present invention, and' the views thereof areas follows: i

"'The -drawing will now be explained. p

' e press 'srovid'ed withaiplaten B and 'ajbedC, the latter fo f'supporting the'usual type form in this class of press.

- As 'is'customary, a tympan draw sheet I is secured to theplaten B by means of a bail 2 40 which is pivoted to the platenin the usual manner.

'In the main, the punch device of thepresent invention, includes a structure having a plurality of leaves; preferably three, the lowermost of which is herein termed the base leaf, the uppermost of which is termed the cutter leaf, and the intermediate leafis termed the stripper leaf. The punch illustrated in Figure", 10 has a base leaf'3 with a downwardly turnedheell atfits50 rear end, for engaging between the platen B' and 7 the bail 2 for {positioning this formoi punch device on the platen; The cutter leaf 5 is of spring metal and it, together with the *intermediate or stripper leaf'i is secured to the base cutter leaf 5 is provided with an opening I!) which j conforms to the shape and 'sizepf the cutter. head 8 for cooperating therewith for punching purposes. The intermediate or stripper leaf 6 is preferably bowed so that normally a portion thereof lies even with or slightly above the cutter head 8 to enable ready insertion of an impression sheet in the punch device. Furthermore the bow-. 7

ing of the stripper leaf enables flexing thereof during the'punching operation asthe flatteningof the stripper leaf during the punching operation enables it to-spring back to normalposition after the punching operation, and thus strip. or

free the sheet from about the cutterhead, so that the sheet may be readily withdrawn. I

The punch device illustrated in Figures 5 and is constructed quite similarly. to that just de- 1 scribed, except that the cutt r leaf I i has portions of its side eliminated, "for increasing the spring effect of the cutter leaf during punching operations.- Also, the base leafis provided with lateral lugs 12 which maybe bent about adjacent portions of the cutter and stripper leaves at the-rear end of the device, for an aid inholding together the leaves, in additior to spotwelding, The punch devices just described-that is those illustrated in Figures 5, 6, 7,8, 9 and 10,; are applied to theplatenB of the press, by inserting the heel or downturned flange 4 between the platen B and the bail 2, as illustrated in Figures 8 and 9, that islpositioning the punch devices adjacent the lowermargin of the platen. I

One, or several, of such devices" maybe readily applied to the platen as the punching job requires. Sometimes it so happens that the impression sheet or other; sheet must be punched in other positions than readily accessible by thepunch devices secured bythebail to theplaten; ';I n order to provide such punch devices, theforms illust t in u e 2, and5 cnv n n The punch device,of .-Figure 2 includes a base leaf l3, a;stripper leaf l4 and a cutter-leaf 15. The e ea l3 ca rie he c ite e d fiw il the stripper leaf is provided with a' suitable aperture to surround this cutterhead, and thecutter leaf is provided with anaperture 17 to cooperate with thecutter head,as. heretofore described. The leaves are secured together adjacent the rear end thereof .as byspot welding. For attachment of this formof punch deviceto the platen, or to the tympan, l8, the base leaf l3 may be extended to receive abolt, l9 havinga flat head 20 which-may be positioned underneath the tympan drawsheet l8, bearing against the underside thereof, with the bolt. passing through a suitable hole inthe draw sheet and through an aperture inthe base leaf l3'of the device. A

nut, 2| is provided to clamp the punch device to the drawsheet in desired position- The base leaf I3, is furthermore provided with tangs 22 which are pointed'and enter the draw sheet I8 to position the toe end of the punch device and retain it in fixed positionduring punching- The punch device illustrated inFigures 3and 4 yice on the platen.

a cutter leaf apertured at 21 to cooperate with the cutter head 26. These leaves are secured together at their rear ends as by spot welding. Adjacent the rear end of the base leaf 23, pins 28 are secured for entering the tympan drawsheet I8 for positioning the rear end of the punch device, while adjacent the toe end of the device are tangs 29 for entering the drawsheet to position the toe end of the punch device.

Itwill beobserved that the punch. device of Figures 3 and 4 may be readily applied anywhere on the surface of the platen simply by inserting the pins through the drawsheet and forcing the tangs 29 into the drawsheet.

The. several leaves of the punch devices are preferably. of. spring metal with the stripper leaf bowed and with the cutter leaf bent so that its free end may lie normally away from the cutter head of the punch device, to allow insertion of an' impression. sheet and also after the punching operation to spring away from. thecutter-head for withdrawal of the punched sheet.

. As an aid in the operation of they punch device, impression pads may, be fl plied'to the cutter leaf. Figure 7 illustrates apad 30 of U-shape in plan, which is of rubber or other elastic material. This pad is applied to the outer surface of the cutter leaf 5 surrounding the aperture -10 therein, with the legs directed towardsthe rear end of the device, to guide the punching's toward thelower end of the platen wherebythesemay fall from the platen after punching operations. H 1

The form of impression pad illustrated in Figures 5, 6, 8 and 9 consists of two separatedpads 3| and 32 of rubber or other suitable elastic material, retained on thecutter leaf bymeans of clips 33 securely fastened to such leaf. The disposition of the two pads 3| and 32 enables theuse of these as guides to prevent lateral disposition of the punchings astheplaten is swung from impression position ,to open positionfor receiving another impression sheet. 5 f
