FIG. 5 is an end elevational view with portions shown 1 cut away to more clearly show the apparatus.

this need an apertured cardconstructed to receive and re-v tain a section of negative film therein was designed as shown in Langan'US. Patent No. 2,587,022. As shown in this patent, the aperture has-a recessed areasurrounding' it which has adepth equal to the thickness of the adhesive sheet mounted therein so that the adhesive sheet and the film combined do not protrude beyond either plane surface of the card. The adhesive sheet is mounted in the recessed area and the central portion thereof is diecut out so that there remains a narrow marginal edge of adhesive sheet protruding into the card structure. A section of film cut to the exact dimensions of the card aperture is then mounted against this adhesive margin and retained therein. 'Since these cards are used in great bulk, automatic apparatuses have been designed to produce them. U.S. Patent No. 2,666,543 issued to Standish is one such machine. In many instances, however, it is necessary to produce just one card at a time and'such automatic machines are not 'useable for this purpose. This invention is directed to such an apparatus to produce a single card at a time. Additionally it was found that the apparatus for cuttingand mounting the adhesive sheet required heavy equipment wherein the die members were finely machined and finely aligned. This invention is also directed to avoiding thenecessity of such accurate alignment of the various parts.

One object of the present invention is to provide an apparatus of the above character which is simple in construction, light in'weight and capable of either automatic or hand operation. 7

Another object is to provide an apparatus of the above character wherein the cutting members are mounted in a novel manner. 1

Another-object is to provide a novel apparatus of the above character wherein the cutting, .mounting and die cutting of each adhesive sheet is accomplished in a single downward stroke of a die member.

Another object'is to provide a novel apparatus for die ing out a central portion of a sheet of material.

Another object is to provide a novel method for preparing an individual apertured card to receive a film section or other record carrying material.

A still further object is to provide a novel and useful semi-finished article which-can be used to receive and retain a section "of film or other record carrying material.

In the drawings there is shown in'FlG. l a statistical card ill of the well known type having an aperture 11 and a recessed area 12 surrounding said aperture. An adhesive sheet 13 is mounted inthe recess 12. Sheet 13 has an aperture 14 which isof smaller dimensions than the aperture 11 sothat a narrow marginal area of the adhesive sheet 13 extends into aperture 11 and serves as a "inafiter. A card holding means and lower'cut'ting knife backing sheet for a film portion which ismounted in aperture ll'and against this adhesive marginal area.

The severing and mounting apparatus comprises a base 17 and an upwardly extending punch support 18 suitably secured thereto. A resiliently mounted multiple blade lower die is mounted to the base 17. A more complete description of this lower die structure will be given herestructure Zil is mounted above the lower die. This structure comprises a plate 21 having an aperture larger than the cutting surface of lower die It? and having the same cross-sectional dimensions as the card aperture 11 and is retained in registry therewith. Secured to the upper surface of plate 21 are a pair of spaced apart and longitudinally extending cutting blades 22 which are spaced apart a distance equal to the length of the recessed area 12 as more clearly shown in FIG. 3. The upper surface of plate 21 is recessed adjacent the aperture therein a sufricient depthto receive the thickness of a card ltl and thereby forming a slot 23. Plate 21 and knives 22, are secured together. Plate 21 is retained in a spaced apart'position from die 19 by bolts Zdsecured to base 17 and having their head portions slidably received through the plate at each corner. Each bolt has an enlarged head so that it cannot understood, however, that the drawings are for the purbe withdrawn. Springs 25 are telescopically mounted over each bolt and are slightly compressed between plate 21 and base 17 whereby the plate and cutting blades 22 are retained away from die 19' A pair of upper blades 28 are pivotally mounted at one end to the support 18 and horizontally spaced apart so that the distance from one outside surface to the other is the same as the distance between the inside walls of the blades 22. Blades 28 are urged outwardly away from each other and into cutting relationship to the blades 22- by the spring 29 mounted between blades 28 as shown more clearly in FIG. 5. A portion. of the outer side surfaces of blades 28 are always confined between blades '22 so that as blades 28 are pivotally lowereda scissor-type action occurs between the two sets of blades and the upper blades 28 are constantly urged into tight cutting relationship with the blades 22.

Positioned above blades 28 are a pairof arms 31) pivotally mounted at one end to the support 1%. The other end of arms 3i) straddle the lower end of a punch shaft 31 which is slidably mounted in the support 13. Each forward end of arms 3-0 has an elongated slot 32 which loosely receives the ends of a pin 33 which extends horizontally through the lower'end of the shaft. In this manner the downward movement of shaft 31 carries'with it the forward ends of arms 30. Arms 30 and blades 28 sisters 3 are resiliently secured together and at the same time retained in a spaced apart position by thefollowing mechanism. A shaft 34 extends between blades 28 and a parallel shaft 35 extends between arms 30. A pin 36 extends through shaft 34 and is secured thereto and its head portion slidably extends through shaft 35. An enlarged head on pin 36 prevents it from becoming disconnected from shaft 35. A spring 37 is telescopically mounted over pin 36 between

shafts

34 and 35 and is retained under slight compression to retain blades 28 and arms 30 in spaced apart relationship.

Mounted to the lower end of punch shaft 31 is a punch 46 having a concave surface 41 and a cutting edge 4-2 having the same dimensions as the aperture 14 in the adhesive sheet.- Punch also has two parallel downwardly depending shoulders 43 which have a length equal to the spacing of the blades 28.

The die 19 is best shown in FIGS. 2 and 4 and comprises a frame having an aperture 51 and transverse spring recesses 52 opening into the walls of the aperture. Die 19 comprises four blades 53, each of which has its upper cutting corner removed as shown at 54. Blades 53 are mounted about die portion 55 and are urged into contact with each other by springs 56 which are retained in recesses 52. Thus as the cutting edge42 of punch 46 is moved into contact with die 19, the corners thereof will first strike the cut away corners 54 of the blades 53 and sever the intervening adhesive sheet beginning at each corner as the downwardly moving punch 40 pushes blades 53 away from each other. A pair of springs 58 each having one end secured .to the support 18 and the other to one of the arms 30, retain the punch 40 and the upper cutting blades 28 in their uppermost position. The

.downward movement of plate 21 and lower blades 22 is limited by the contact of the lower surface of the plate and the upper surface of die frame 50.

The adhesive sheet 13 is severed from an endless strip of adhesive material which is commercially available in rolls in which the adhesive surface is covered with a glassine protecting strip. The roll of glassine covered adhesive strip material 60 is rotatable, supported in a frame 61 which, in turn, is suitably secured to the base 17 and adjacent the die 19. A glassine stripping roll 62 is freely rotatably mounted forward of the roll of adhesive material 60. Idler rolls 63 and 64 are rotatably mounted on the frame and are in circumferential contact with the separating roll 62.

In operation the strip 60 of adhesive material is threaded around the idler roll 63 and over the roll 62 where the glassine is separated from the adhesive sheet. The stripped adhesive sheet is extended over the cutting surfaces of lower blades 22. A guide 65 extends upwardly adjacent one of the blades 22 and serves to correctly position the strip over said blades. After the strip is positioned over the blades 22, a card is positioned in slot 23 with its aperture in register with aperture in plate 21 and the punch 40 is lowered by the application of pressure to the top of shaft 31. As shaft 31 moves downward it carries with it arms 30 and blades 28 with the same spacing maintained because of spring 37. In this manner blades 28 are pivotally carried into telescopic relation with blades 22 thus severing the strip in two places. Strip 60 has a width equal to the width of the recessed area 12 in card 10 so that the severed section 13 of strip 69 has the same length and width as said recessed area. The severed section 13 is carried into engagement with the card 10 by blades 28. Blades 28 continue their downward movement and the lower surfaces thereof press the two out edges of the adhesive sheet 13 into contact with the card 10 while at the same time overcoming the resistance of spring 25 thus causing the card support plate 21 to be depressed until its bottom surface is in contact with the upper surface of the die frame 50. Up to this point the punch 40 has maintained its relative position to blades 28- but upon continued downward movement of shaft 31, the resistance of spring 37 is overcome and punch 40 advances downwardly in relation to blades 28 causing the cutting edges 42 of the punch 49 to engage and cut out the central portion of adhesive sheet 13 in co-operation with the die 19. The punch 46 continues downwardly into die 19 until the shoulders 43 contact the other two parallel edges of sheet 13 and press these edges into contact with the card. Upon the release of pressure on shaft 31 the springs 58 return the shaft together with the punch 40 and blades 23 to their uppermost position. At the same time springs 25, which have been compressed by the downward movement of plate 21, push said plate and blades 22 to their uppermost vertical position and at the same time strip the card 10 from the die members 53.
