(Cl. 83-444) This invention relates to a method of and an apparatus for mounting record bearing sections, such as sections of micro-film, in aperture cards.

One of the objects of the present invention is to provide a novel method of cutting or blanking out a section of record bearing strip, such as micro-film, and for forwarding such cut section and pressing it into .and securing it in an aperture in a card. I

Another object of the invention 'is to provide novel apparatus for cutting a record bearing strip, such as micro-film, into individual sections, for forwarding such cut sections, and for mounting them in apertures in cards.

A further object of the invention is to provide novel apparatus of the above character wherein the sections to be cut from the supply strip may be viewed for selection and/or positioning purposes prior to the cutting or blanking out of such sections and the mounting of them in the apertures in the cards.

Yet another object of the invention lies in the pro vision, in apparatus of the character indicated for. cutting cuts extending completely across the strip, of an improved combination of means for guiding the strip into cutting relation with the cutting apparatus which forms the sections.

Still another object is to provide an improved cutting means wherein the movable die element is maintained in very accurate parallelism with the fixed die element at all times.

A further object of the invention resides in the provision of improved means for guiding and locating the cards with respect to the section-cutting, forwarding, and

pressing means, whereby accurate registry between the cut strip sections and the apertures in the cards is assured.

The above and further objects and novel features of the present invention will more fully'appear from the following detailed description when the same is read in connection with the accompanying drawings. It is to be expressly understood, however, that the drawings are for the purpose of illustration only and are not intended as a definition of the limits of the invention.

FIG. 11 is a schematic view in horizontal section through a film strip, an apertured card, and elements of the strip-cutting and. section-mounting means cooperating therewith, the elements of the apparatus, the film strip, and the card being shown in the relative positions which they occupy at the start of the cutting and mounting operation, the section through the-card being taken generally along the line 11-11 of FIG. 10;

FIG. 12 is a" view similar to FiG. 11, but with the film strip, the card, and the parts of the apparatus generally in the positionsthey occupy at the end of the film section-mounting operation; and

FIG. 13 is a schematic view in longitudinal axial section through a complete film scanning, cutting and mounting system of which the apparatus shown inFIGS. 1 to 9, inclusive, may be employed as a part.

Referring now to the drawings, there is shown in FIGS. 1 to 9, inclusive, by way of example, one form of strip feeding, cutting; and mounting apparatus constructed in accordance with the present invention. Such apparatus, as will be understood after consideration of FIG. 13, is adapted to be used ina system which permits the scanning of the record bearing strip while it is being fed, and before the individual sections are cut therefrom and mounted. Such system, and the apparatus of the present invention, are particularly, although not exclusively, adapted for mounting individual sections-or frames of micro-film in apertured cards of the record type commonly employed in connection with known and existing record card tabulating and sorting systems and machines. It will be understood, however, that the present inven tion is not limited to the mounting of film sections in the statistical or tabulating machine type of card, since other forms of record or catalogue cards, as well as ordinary cards may be used for this purpose. Additionally, apparatus in accordance with the present invention may be used to advantage for mountingrecord bearing and other sections, which may be transparent or translucent, or in some instances opaque, in apertured cards or cardlike structures for various purposes. For simplicity the strip 15' from which the sections are severed for mounting in cards It is herein called film.

For purposes of illustration only, there is shown in FIGS. 10, 11, and 12. one form of card, designated 10, which is of the statistical or tabulating machine type. In FIG. 10 the card is shown as having a rectangular aperture 11 in which there is mounted a section 14 of microfilm. Asindicated in FIGS. 10 and 12, the section or frame 14 of micro-film fits accurately within aperture the card ltl so. that the outer face of the border' lies flush with theface of the card; a

In accordance with the described-embodiment of the method and apparatus of the present invention, the aperture 11 in the card; is made of such width, or vertical dimension as herein shown, that it'accurately' receives the uncut longitudinal edges of the film section 14, thereby economically utilizing the full width of the film. This requires the cutting of the film strip '15 with but one or two, two when the leading edge of the strip must be trimmed, transverse cuts extending completely across the film strip so as to provide a film section of such length as to accurately fit between the end walls of the aperture i is aligned with 'assemblyg32 Assembly 32 includes the above-mentioned condensing lens set 20, and the trans-' parent anvil plate 56, a card guide and support (to be described), the card end-stop-1il6, the female die 16, and

guides for the film supply, strip 15 (also to be described). Assembly 34 includes the male die 17, means for reciprocating'and guiding the male die, and means operated by, advance of the male die for retracting upperand lower,

movable edge guides (to be described) for the film supply strip 15, said retractable guides normally projecting into the passage through the female die 16 and being aligned with the path of travel of the film strip 15 into the apparatus.

11 in the card 10. Not only does such construction ine crease the useful area of the fihn section, butit also produces a film section-bearing card of substantially uni- I of the apparatus of the invention, will be generally'understood upon consideration of FIGS. 11, 12, and 13, which schematically depict'the operation of the illustrated embodiment of the apparatus. a A card 10, prepared with an aperture 11 and with an adhesively coated border 12,

. ispositioned at the film section-mounting station of'the apparatus upon a lower guide, to. be described, and in abutment with an end stop 106. At such station the aperiture'd portion of the card It) is centered With respect to the cutting dies, and is held between the front end of Assembly 32 has a main generally L-shaped support'or bracket 33 having a horizontal portion 35 resting upon supporting plate 29, and a vertical transverse portion 42 (FIGS. 1, 3 and 5 Triangular side portions or webs 44 connect and mutually brace the

portions

35 and 42, as shown. In order to insure accurate positioning of the bracket 33 on plate 29, the latter is provided with a longitudinally extendingcentral groove 36 in the upper surface thereof, and 'slidably engagedin said groove are downwardly extending keys 37 which are affixed to the lower surface of the portion 35 of said bracket. The bracket 33 is finally secured in its accurate position against displacement by bolts 39 which extend through clearance holes in flanges 4t) and 41 on said bracket and threadedly engage the plate 29.

The condenser assembly 20 (FIG. 4), which consists of a front condenser lens 45 and a rear condenser lens 46 spaced therefrom, is carried in a cylindrical can-like housing 47. The condenser lenses 45, 46 are held in spaced relationship within the housing 47 by an interposed spacer 'sleeve 49, The housing 47 with its contained lenses 45,

the outer or female die 16and the: rear surface of a transparent anvil or backing plate 56. Theiforward end of a film strip 15 is fed endwise between the rear end of female die 16 and the front end of a hollow male die or punch 17. The endwise positioning 'of the film stripv 15 with respect to the dies 16, 17 is under the control 'of the operator,--who is able to scan the film strip as it is fed between thedies. As'shown in FIG; 13, light from a source 21 passes through a condensing lensrunit 20, the anvil plate 56, the female die 16,

and ;.the malevdie 17, in that order. The beam tof light emerging from the male die 17' passes sequentially through a lens 22 and a prism 24, being then reflected successively by mirrors 25 .and 26 to fall upon the rear surface of a translucent screen 27 which faces the operator.

After the film strip 15 has been advanced into the correct position, generally in which its leading edge at least slightly overlies a second cutting edge of the female die 16 (FIG. 9), the movable male die or punch 17 is then advanced in the direction of the arrow in' FIG. 11, Whereby it cuts a frame or section 14 from the leading end portion of the film strip. Continued advance of the male die 17 moves the thus cut film section 14 through the passage in the female die 16 and inserts the section into the aperture 11 in the card. Finally, at the end of its advance stroke, the male die 17 presses the marginal edges of the'severed film section 14 into forcible engagement withthe adhesively coated face of the portion of border 12 extending into the card aperture 11, so that the film section 14 is substantially permanently bonded to said border and mounted in the card.

. Turning now'to a detailed description of the apparatus 4-6 is mounted on the rear surface of a suitably apertured vertical plate 50 which is disposed between the triangular web's" 44 of the bracket 33 and is secured in position to said bracket by bolts 52 passing through horizontal plate portions 51 which are integral with plate 50.

The front face of the vertical portion 42 of the bracket 33 has a central annular recess 54 (FIG. 4) within which is mounted the transparent anvil member or plate 56 and the supporting means therefor. The anvil member 56 is made, for example, of thick plate glass, and the supporting means for said anvil member includes a bezel ring 55 and a front retaining ring 59 to which the bezel ring is scribed anvil plate assembly is immovably secured within the recess 54 to the bracket portion 42 by screws 61 (FIG. 5) which extend through the outer rim portions of retaining ring 59 and of bezel ring 55 and have threaded engagement with the adjacent wall 62 of said bracket portion at recess 54, said wall having a suitable central annular opening 63 therein through which said anvil plate assembly projects. The rear edge of bezel ring 55 lies flush with the rear face of anvil plate 56, and both such surfaces lie flush with the inner, rear surface of the wall 62 which defines a rectangular recess 74 in the rear face of the bracket portion 42. Thus recess 74, the anvil member 56, and the'rnoun ting ring 55 for the latter present a flat imperforate surface for guiding cards 10, as will more fully appear. Recess 54 is made of such depth, and the condenser assembly 20 is so located, that the rear end of the condenser assembly is telescoped within the outer end of said recess and into substantial engagement with the retaining ring 59 so that substantially no light escapes laterally from between the condenser assembly A and the bracket portion 42;

The female die 16, for cutting the strip 15 into individual sections, is mounted on the rear face of the bracket portion 42 coaxially of recess 54 in said bracket portion. The construction of the die 16 will be apparent upon consideration of FIGS. 4, 6, and 7. As shown in FIG. 6, the die 16 is made up of similar upper and lower sections 65 and 66, respectively, andof similar right and left

side sections

67 and 69, respectively, such sections being connected together as an integral assembly. The four connecting means shown for this purpose each takes the form of a locating sleeve 70 (FIG. 6) extending inwardly through a side section into the respective upper and lower central sections and fitted to snugly engage said sections, and a machine screw 71 disposed within and extending through the sleeve and threaded into the respective central die section. Such construction facilitates the machining of the parts of the female die 16, the replacement of wearable parts thereof, and the assembling of the operable guides (to be described) cooperating with the edges of the film strip 15 in alignment with the die 16.

The thus assembled composite female die 16 is rigidly secured to the bracket portion 42 by machine screws 72 (FIGS. 6 and 7). The compositefernale die 15 is formed on the front side thereof with a forwardly protruding central portion 75 (FIG. 4) which extends into the recess 74 in the bracket portion 42 such that the forward face of said die portion is spaced from the rear surface of the anvil member 56 a distance which slightly exceeds the thickness of card it thus forming a card-receiving slot 76 between the female die 16 and the anvil member 56.

The female die 16 has a passage 13 therethrough of the same size and shape as the section to be cut from the film supply strip 15, and also the same as the Vertical cross-section of the male die or punch 17, said passage being defined by the lower and upper surfaces of the upper and lower die sections 65 and 66, respectively, and by the inner surfaces of the side die

sections

67 and 69, and being located so that the center thereof is coaxial with the axes of the anvil plate 56 and lens unit 2%. Each of the

side sections

67 and 69 of die 16 has a laterally extending vertically disposed strip-receiving passage therethrough, one such passage 79 through section 67 being shown in FIG. 9. The hiner edge of the forward surface of each of the laterally extending stripreceiving passages 79 is in the form of a shearing edge, such edge on the die section 67 being designated 77 (FIG. 9). As shown in FIGS. 4, 6 and 9, the forward surface of each strip-receiving passage 79, which provides the above-described shearing edge 77, is of shallow rearwardly facing concave shape and is symmetrically disposed vertically relative to the central horizontal plane therethrough. Consequently, upon cutting movement of the male die or punch 37 relative to the female die 16, the film supply strip 15 is first shearingly engaged between said dies at each of the four corners of the strip section to be cut out, the cuts then extending progressively inwardly toward the horizontal center line of such strip section upon continued movement of the die 17. In order to facilitate manufacture of each of the

side sections

67 and 69, the forward portion thereof, indicated at 89 (FIG. 9), which contains the described concave shearing edge 77 is fonned separately from the main body thereof and is rigidly secured to said main body as by rivets 81 (FIGS. 6 and 7).

The card 10, upon its edgewise introduction by the operator into the slot 76 between the anvil member 56 and the forward face of the female die 16 from the lefthand side of the apparatus as viewed in FIG. 3, is accurately located with the aperture 11 of the card in exact vertical and horizontal registry with the longitudinal passage 18 through die 16 by card-locating means now to be described. Turning particularly to FIGS. 5, 6, and 7, in which the card-locating means is most clearly shown, it will be seen that there is a flat vertical plate 82 which is disposed parallel to and is spaced rearwardly from the rear surface of the anvil plate 56. This plate 82 extends laterally outwardly of the bracket 33 and inwardly a short distance beyond the adjacent side of said bracket and forms, with the beveled surface 89 (FIG. 2) at the card-entering edge of the bracket portion 42, a narrow throat into which the leading edge of the card 10 is introduced. Plate 82 is supported on the bracket portion 42 by means of upper and lower hanger strips 84 and 85, respectively, which are soldered or of plate 82 is a horizontal transverse bar or ledge 99, which has an appreciable width in a direction forwardly. from said plate and is loosely receivedto a substantial depth in a horizontal transverse groove 91 (FIGS. 4 and 5) formed in the rear face of the bracket portion 42. The depth of the groove 91 and the width of the ledge 9b are such that said ledge extends forwardly beyond the vertical plane of the rear surface of theanvil plate 56. The plate 82. extends inwardly to substantially the adjacent side die section 67, and the ledge extends between the bracket portion 42 and the female die 16 to a location laterally beyond. the opposite side die section 69.

To support the free end of the ledge 90, there is provided an elongated vertical hanger strip 92 (FIGS. 5 and 7) which is soldered or otherwise suitably secured at its lower end to the rear surface of said ledge and adjacent the free end thereof. Hanger 92 provides for accurate vertical adjustment of the free end of the ledge 90 and, when clamped to the bracket portion 42 by means of

machine screws

94 and 95, secures said ledge in adjusted position. The

screws

94, 95 extend through enlarged openings in the hanger 92, as clearly shown with respect to screw 94 in FIG. 5, and are threaded into the bracket portion 42. Vertical adjustment of plate 82 and ledge 94}, when screws 86, 87, 9'4, and-95 have been loosened, is effected by means located at the upper end of each of the

hangers

84 and 92 and interacting with the bracket portion 42. As shown, the hanger strip 84 has a forwardly bent horizontally disposed flat finger 96 i at its upper'end, and a machine screw 99 extends through a clearance opening in said finger and is threaded into the bracket portion 42. A coil compression spring 97 (FIG. 3) is located between the bracket portion 42 and the finger 96 and surrounds the' screw 99, so that when the screw is rotated in one direction, the

hangers

84, 85, plate 82 and ledge 90 are moved downwardly by said screw in opposition .to the tension of said spring, and when the screw is rotated in the opposite direction, said hangers, plate and ledge are moved upwardly by the expanding action of the. spring 97. The hanger strip 92 is provided with a similar means for vertical adjustment of the same and the ledge 99, said means comprising a forwardly extending horizontal finger 1% at the upper end of said hanger strip, a machine screw 1G2 extending through a clearance opening in the finger and threaded into the bracket portion '42, a coil compression spring 101 (FIG. 3) disposed between said bracket portion and said finger and surrounding said screw. Because the groove 91 for the ledge 90 is substantially wider vertically than said ledge, not only is the ledge free for substantial vertical adjustment,'but it may also be appreciably tipped in its plane if required to bring a card it) supported thereon into proper position for accurate vertical registry of its aperture 11 with the passage 18 through the female die 16.

An end card-stop assembly, generally designated 104 (FIGS. 5, 6 and 7), is provided to locate each card 10 in the proper lateral positionfor' accurate'horizontal reg istry of its aperture 11 with the passage 18' through the female die 16'when the card has been fullyinserted into the slot 76. Asshown, the stop 104 has a flat body 105, made, for example, of sheet metal, which overlies the rear face ofthe bracket portion 42 at the side thereof opposite the card supporting and guiding plate82. Body 105' has soldered'or otherwise suitably secured to the inner edge thereof a vertically disposed ledge or bar 106 which is of an appreciable width and is loosely received to a substantial depth in a relatively wide vertical groove 107 formed in the rear. face ofthe bracket portion 42. Ledge I 106 extends forwardly and :rearwardly beyond'the plane of the rear surface of anvil plate 56 to generally the same extent as does ledge 0.

Body 105 of the'card-stop assembly 194 is formed with two forwardly'bent vertically spaced and vertically disposed flatfingers 109 which overlie and are spaced somewhat laterally fromthe adjacent side of the bracket por ]?1101142 (FIGS; 1 and Between each of'the fingers 109 and the bracket-portion, there is disposed a coil compression spring 110. Ascrew 111 extends through a clearance opening in each of the fingers 109, through spring 110, and is threaded into the bracket portion 42.

As shown in FIGS. 5, 6, and 7, the above-described hanger strip 92 overlies the body 105 of the end stop 104. Accordingly, the

screws

94 and 95 also extend through enlarged openings (not shown) in the body 105. When the screws 94 and 915 are loosened, the end stop 104 may, by simply turning the screws 111 in the proper direction, be adjusted laterallytoward and away from the female die 16 to vertically align the ledge 106 and to 1 bring said ledge into proper lateral position with respect to the passage 18 through said die. Thereupon, assuming, that the ledge 90 has also been properly adjusted as hereinbeforefdescribed, screws 94 and 95 are tightened, thereby clamping the end stop 104, as well as the hanger strip 92, against the bracket portion 42 to iminovably hold said endstop and the ledge 90 in their proper adjusted positions; a

The film strip 15 is led laterallyof the'female die 16 so as to pass throughithe passages 79 in the side sections;67 and69 thereof rearwardly of the cutting edges 77 insuch side die sections. The film strip 15 isguided accurately for presentation to upperand lower retractable guides 175 aud176 (tobe described) lying generally within the passage 18 through the. die 16 by a vertically disposed film strip-recei-ving guide channel 112 (FIGS. 1,6 and'7) positioned laterally of said die at the entrance side thereof. Channel 112 is provided with a cover 114 secured to the edges of the channel, as shown in FIG. 6. Laterally spaced from the side of die 16 through which the film strip 15 enters, is a supporting bracket 113 (FIGS. 1 and 3) which is. bolted or otherwise suitably secured to the top of the supporting plate 29. A supply reel 115 for the film strip 15 is supported on an annular plate or platform 116. To allow for vertical adjustment of the alignment of the film strip 15 as it is fed off reel 115 into the guiding channel 112, the reel supporting plate 116 is rotatably carried by a post 117 which is suitably secured in the plate 29' for vertical ad, justment. To .prevent'over-running or coasting of the reel 115 relative to the plate 116 during the film feeding operation, the platform 116 has adhesively secured.

thereto an upper layer of friction material 119, such as cork, upon which the lower flange of reel 115 rests. The

weight of the reel 115 and its contained supply of film strip, therefore, acting with facing 119 imposes a suitable retarding torque on the reel 115. e

As shown in FIGS. 1 and 3, the film strip 15 upon leaving the reel 115 passes between pinch rolls 120 and 121, the nip of which is aligned with channel 112. 'Roll 120 is selectively manually driven by means to be described.

Roll 121 is idle and is pivotally mounted upon the'bracket 113 so as who movable toward and away from driven 124 connected to the bracket 113 and to the free ends of the arms 122 constantly urges roll 121 toward roll 120, in order to maintain suitable frictional engagement between the film strip 15 and the roll 12%. Prefer: ably, when the roll 121 engages the emulsion side of the film strip 15 as in the embodiment of the apparatus shown, such roll is provided with an outer covering layer of resilient material, such as rubber.

The film feeding roll is selectively rotated by the operator by means including a cross shaft (FIGS. 1 and 3) rotatably mounted adjacent one end thereof in a bearing 123 on the bracket 113, and adjacent the other end thereof in a bearing in a pillow block 128 bolted or otherwise suitably secured to the plate 29. The shaft 125 extends through suitable clearance openings in the Webs '44 of bracket 33 and has-secured thereto a spiral gear 126 which meshes with a similar spiral gear 127 which is secured to a vertical shaft 118. The roll 120 is secured to the shaft 118 and thelatter is joumalled in suitable parallel upper and lower projections of the bracket 113. A shaft-turning knob 129 is secured to each end of the cross shaft 125, so that the may be fed conveniently by the operator from either side of the apparatus. It will be apparent that the film strip 15 may be fed from the reel 115 intothe lateral passages 79 and across the central passage 18 in the female die 16 to the extent required for the cutting of each successive complete frame of film, as indicated by the image of such frame projected upon the screen 27, and that, if necesary, the positioning of a complete image may be. very accurately determined by turning the shaft 125 in either direction, as required, when the film frame approaches the desired ultimate frame cutting position.

The rear assembly 34 of the apparatus has a main bracket'130 (FIGS. 1, 2 and 4) which is centrally positioned upon theplate 29 rearwardly of and in axial alignment with the previously described assembly 32. To insure accurate alignment of assembly 34 with respect to assembly 32, keys 131 are provided on the bottom surface of the bracket 1341 to slidably interfit with the longitudinal groove 36 in the plate 29. The bracket is secured to the plate 29 for limited longitudinal adjustment therealong by bolts 132 which extend through elongated holes in flanges 134 on said bracket and are threaded into said plate.

A cross-head 137 (FIGS. 1, 2, 4 and 8), which carries the male die or punch 17, is located at the forward end of the bracket 130 and is supported for rectilinear movement toward and away from the female die 16. The die or punch 17 is provided with a flange 139 at its rear 'end, such flange being secured against the forward face of cross-head 137 by bolts 140 (FIG. 8). Cross-head 137 and punch 17 are supported and accurately guided for rectilinear movement parallel to the film-frarne-receiving passage 18 through the female die 16 by upper and lower horizontal guide rods 141 which extend rearwardly from and are suitably secured in the sections 65 and 66 of said die, and are slidably engaged in bushings 141' fitted in the cross-head 137, as shown in FIG. 4.

To further support and guide the cross-head 137, and to counteract that component of the thrust exerted by toggle type cross-head driving means which lies at an angle to the longitudinal common axis of the dies 16 and 17, there are provided additional guide means for said cross-headwhich areshown most clearly inFIG. 8. As shown, said additional guide means comprises similar spacedconfronting tracks 142 which are bolted or otherwise suitably secured to the bracket 130 and are located at each side of the cross-head 137. Anti-frictionrollers 143 journalled on stub shafts 147 which are suitably secured in the cross-head 137 and lie 'in a horizontal axial plane through the punch 17, are accurately received between the upper and lower horizontal surfaces of the tracks 142. Because the forward ends of spaced horizontal links 146 are likewise connected to the stub shafts 147, and are located immediately adjacent the rollers 143, such rollers and the tracks142. effectively prevent the transmission to the cross-head 137 and punch 17 of all forces other than those in a horizontal plane. As a result, the cross-head 13-7 and the male die or punch 17 mounted thereon, are Very accurately guided for rectilinear movement along the axis of the female die 16.

The upper rear corners of the bracket 13% are made in the form of spaced parallel ears 144 (FIGS. 1, 2 and 4). Pairs of similar links 145 are pivotally connected at their rear ends to the ears 144, there being one of said links at each side of each ear. The forward ends of one pair of links 145 are pivotally connected to the rear end of one of the links 146 which extends between said pair of links. The forward ends of the other pair of links 145 are pivotally connected to the rear end of the other link 146 which also extends between said pair of links. The

links

145 and 146 thus form two similar toggles which, when pivoted upwardly, in the illustrated embodiment, towards and to collapsed position shown in FIG. 4, retract the punch 17 from its operative film cutting and mounting positions, and, when pivoted downwardly toward and to extended substantially horizontal position, thrust the punch 17 forward Within the female die 16 in an operative stroke of a predetermined extent to thereby effectively sever a film frame 14 from the film strip 15 and mount said film frame in a card To operate the

toggles

145, 146 and thus to reciprocate the male die or punch 17, there is provided an operating lever having an equalizing type of linkage interposed between it and said toggles. The linkage includes a cross bar 149 (FIGS. 1 and 4) having pivotally connected to opposite ends thereof the lower ends of spaced parallel links which extend upwardly between each of the pairs of links 145 of the respective toggles and are pivotally connected to the latter links intermediate the ends thereof. The cross bar 149 is provided centrally thereof with centrally disposed upper and lower concave seats 15-1 and 152, respectively. Washers 154 having similarly curved surfaces are disposed in the

seats

151 and 152; and engaged over the upper annular end of a threaded connecting rod 155. The described connection between rod 155 and cross bar 149 is such as to allow rocking of said cross bar as required to correct any slight misalignment of the respective pairs of links 145 so that the movement imparted by said links to the punch 17 is equal at both sides of said punch, and canting and jamming of the punch within the female die 16 is avoided.

Connecting rod 155 is adjustably secured, as shown in FIG. 4, in a block 156 having spaced ears 166 depending therefrom between which is pivotally engaged the free end of one arm 165 of a bell-crank lever 164, the other arm of which is indicated at 167. The arm 165 of hellcrank lever 164 is pivotally connected to the block 156, and said bell-crank lever is keyed to a cross shaft 157 which is rotatably supported beneath plate 2% in pillow blocks 158 secured to said plate. Outwardly of the pillow blocks 158, as best shown in FIG. 3, shaft 157 has terminal fittings 15? (left) and 160 (right) non-rotatably secured thereto. An operating lever or handle 161. may be secured into either of terminal fittings 159' and 16 3', so that the film cutting and mounting apparatus may be operated by either the right or the left hand of the operator.

A yoke 171 (FIGS. 2, 3 and 4) is bolted to the bottom of plate 29 in position to receive between the parallel vertical legs thereof an extension 174} on the arm 165 of hell crank lever 164. The upper surface of extension 171) is adapted to abut against the lower end of an adjustable stud 172 threaded in the yoke 171, whereby to determine the fully retracted position of the male die or punch 17. An adjustable stud 174, threaded into the bight of the yoke 171, cooperates with the lower surface of the bell-crank-arm-extension 170 to determine the desired position of furthest advance of the male die or punch 17. A coil extension spring 169, connected to the outer end of the other arm 167 of bell crank lever 164 and to a stud 173 secured to the table 29 constantly urges the operating handle 161, the bell crank lever 164, the connecting linkage, and the

toggles

145, 146 into the position shown in FIG. 4 in which the male die or punch 17 is fully retracted. I

In order to facilitate accurate positioning of the rear assembly 34 along the table 29" with respect to the front assembly 3-2, and the anvil plate 56, there is provided an adjustable stop screw 135 which is threaded through a block 136 secured to the plate 29 and is arranged to engage the bracket 13d! of said rear assembly. Upon loosening of the bolts 132 for the bracket 130, and rotation of the stop screw 135 in either direction, minute longitudinal adjustments of the rear assembly 3-4 may be effected. Following this, the bolts 132-are again tightened to immovably retainthe rear assembly 34 in the desired longitudinally adjusted position.

The above-mentioned retractable film guides 175 and 176 associated with the female die 16 are shown most clearly in FIGS. 4 and 6. In both such figures the guides are shown in their inner, operative positions. The guides 175 and 176 proper confront each other and each is in the form of a relatively thin and narrow elongated memher which horizontally spans across substantially the entire distance between the confronting cut-defining side surfaces of the

side sections

67 and 69 of the female die 16.

Each guide 175 and 176 is formed with a narrow horizontal groove or slot 178 in the inwardly facing surface thereof, said groove opening outwardly through said surface and through opposite ends of said guide. The guides 175 and 176 are adapted to-receive in the grooves 178 thereof the upper and lower edges, respectively, of the film strip 15 after said strip has been advanced through the fixed guide 112 and the passage 79 in the first die section 69, and as the same is advanced across the openor passage 18 in the die 16, whereby bowing of the film strip 15 forwardly or rearwardly within the die passage 18 is prevented, and said film strip is caused to remain flat and to pass accurately and unobstructively from the passage '79 in the first die section 6?, across the die passage 18 and intothe passage 79 in the second die section 67. in this mannensevered film frames or sections 14 of uniform length and of the required length are always obtained. When the guides .175- and 176 are in their inner, operative vertical positions, shown in FIGS. 4 and 6, to receive the film strip 15, the bottoms of the grooves 178 therein are horizontally aligned with the upper and lower edges, respectively, of the fixed guide 112, and substantial Widths of the guides and 176 protrude into the die opening 18 and thus into the path of operative movement of the male die .or punch 17.

The guides 175 and 176 are suitably secured centrally thereof to the inner ends of vertically aligned plungers 177 which extend vertically from said guides and are slidingly received in bores 179 formed in the central sections 65 and 66 of the female die 16. Each of the guides 175 and 176 is further guided for vertical reciprocal movement by a central pilot pin 181 which is formed integrally with the respective plunger 177 and is accurately and slidingly received in a smaller diameter bore 186 formed in the respective die section 65, 66. Each of the guides 175 and 176 is constantly urged inwardly toward the axis of the die 16 by a coil compression spring 182 surrounding the respective pin 181 and disposed between the respective plunger 177 and the outer end of the respective accurately. locate theguicles vertically in their innermost operative positions, shown in FIG. 4, with thcir respective grooves 178 accurately disposed to receive the film strip therein. i

It is, of course, necessary to retract the guides 175 and 176 from the path of movement of the punch 17 before said punch, in its operative stroke, reaches the position of said guides. In the embodiment of the apparatus shown, such retraction of the guides 175 and 176 is automatically efiected by means in the form or" two pins 137, se-

cured in the flange 139 of the punch 17, and projecting forwardly therefrom. The pins 187 cooperate with the plungers 177 of the guides 175. and 176 and each pin has a conical forward end 1911 which, when the punch 17 is in its fully retracted position shown in FIG. 4, is located relatively close to but clear of itsrespective plunger 177. t

a Each of the plungers 177 has a flat rear face 184 and has a pin-receiving bore 185 therethrough. The die sections 65 and 66 are each provided with a bore 186 whichis axially. aligned with the respective pin 187 to receive said pin. 'The bores 135 in the plungers 177 are so located that their axes lie inwardly of the axes of the pins 187 when the guides 175 and 176 are in their innermost operative positions shown in FIG. 4, so that when the punch 17 has been advanced to and beyond the zone of" the guides 175 and 176, the guides through'movement of the pins 187 into the offset bores 185 inthe plungers 177, are vertically cammed and thus retracted by said pins so that the inner edges of said guides lie at least flush with the upper andlower inner surfaces of the die passage or opening 18; To facilitate entry of the pins 187 into bores 185 in plungers 177, the rear ends of said bores are chainfered, as'shown in 516.4.

The outer side portions of the punch or male die'17, which perform the cutting operations, are preferably made separate from the main body of such die. As shown in FIGS. 7 and 9, such side portions are in the form of individual blades 23 which are recessed into/the body of the punch 17 flush with the outer side surfaces of said punch. ;The blades 23 are removably held onthe body of the punch 17 by pins 28 which are loosely received in said blades and are held in said body by a push fit, said pins in all positions of said punch being retained against accidental outward displacement by the adjacent die sec-'

tions

67 and 69. Thus the activeportions or blades 23 of the punch 17 may be easily and quickly removed, as for sharpening, by merely retracting the punch suificiently to clear the die 16 without disturbing the otherelernents of the apparatus. When it is necessary to sharpen the edges 77 of the female die 16, as by grinding, it is only necessaryto remove the

die sections

67 and 69 from the,

machine,

The operatiop of the apparatus will be readily unden stood from the foregoing description and may be briefly Assume that the lamp 21 has summarized as follows. 7 been illuminated, and that the film strip 15 has been drawn from. the supply reel 115. and has been threaded. between rolls 120 and 121and thence into the guide 112-- .Also assume that a plurality of similar cards 19 are to have film sections or frames 14 mounted in them, and, that the card supporting and guiding ledge 96 has been suitably adjusted to make the longitudinal center line of from engagement with the film strip 15 that the upper and lower edges of said film strip enters the opposing grooves 178 in the upper and lower retractable guides 175 and 176, respectively. Feeding of the film strip 15 is continued until said strip has passed along the guides 175, 176, and, hence, across the die opening or passage 18 in the die 16, and'has at least partially entered the lateral passage 79 in the other'section 67 of said die, as indicated in FIG. 9, and the image onthe screen 27 indicatesthat the full image or picture on the frame of the strip' to be cut out is in accurate register with the opening 18 through the die 16. In the event that the film strip 15 is advanced too far, as indicated on the screen 27, it may, of course, be retracted to bring the image or picture on the strip into accurate register with the dies simply by turning shaft 125 in the reverse direction. As shown in FIGS. 4 and 7, the punch 17 is formed with relatively thin outer'walls, thus leaving a rectangular passage 38 of substantial. size extending axially therethrough and through the flange 139, and communicating at the rear end thereof with a similar passage 43 of substantially the same size formed in and extending axially through the cross-head 137, to enable projection of the film-strip-irnages through said passages upon the screen 27.

Preferably the film feeding'and image centering operations are carried out before the insertion of a card 14) into the apparatus, so that there is no possibility of partially obscuring the edges of the projected image bythe card or by the border 12 on the card. Assuming that the projected ir'nage'has been properly centered with respect to the die passage 13, as seen on the screen 27, the card 10 is then inserted edgcwise into the correct position, as above described, with the adhesively coated surface of the border 12 facing the film strip 15 as shown in FIG. 11. With the retractable guides 175 'and176 still in their innermost film strip guiding positions, the operator then depresses the outer end of the handle 161, thereby causing the cross-head 137'to approach the die 16, and the punch 17 carried by said cross-head to move farther into, said die. Before the forward end of the punch 17 reaches the retractable guides 175 and 176, the forward conical endslfifi of the pins 187 will have entered the passages 135 in the plungers 177, thereby raising and depressing the guides 175 and 176, respectively, so that they are completely removed from the path of the punch 17 and Immediately thereafter, the four corners of the film section to be cut from the film strip 15 are clampingly engaged between the outer elevated ends of the cutting edges 77 of the die 16 and the forward cutting edges of the blades 23 of the punch 17, thus preventing any movement or displacement of the film section out of propefrregistrywith the dies.

Continued forward movementof the punch 17 causes the film section beingcut to be moved forwardly and to be progressively sheared at its edges by cuts extending inwardlyfrom the corners and lying along the planes of the cutting edges 77. The progressively cut edgesof the film section lie forwardly of the outer ends of the cutting edges 77 which the cut film edges have passed, so that the film section is accurately guided at all times as it is being cut and as it travels in a forward direction. When the forwardcutting edgesof the blades 23 of the punch 17 have passed beyond the central, lowest points of the cutting edges 77, thefilm section 141will' have the apertures 11 in the cards coincide with the horizontal central planethrough the aligned dies 16 and 17, and that the end stop 106 has been suitably adjusted so that when a card 10 is fully inserted into thecard guide in engagement with the step 106, the central vertical axis of been entirely severed from the film strip 15. The severed film section 14 is then moved forwardly lay-the forward fiat rectangular end of the punch 17, being guided by the upper and lower non-cutting inner surfaces of the die 16 and'by the inner side surfaces of said die forwardly of the cutting'edges 77. As the punch 17 approaches 13 the end of its forward movement, the severed film section 14 will be introduced by said punch into the aperture 11 in the card 10, and will be firmly pressed by the punch into engagement with the adhesively coated border 12 around the aperture 11 on the card at the end of said movement. During such latter operation, the card and the border 12 thereof are backed up by the transparent anvil member 56, as shown in FIG. 12. The accurate positioning of the rear bracket 130 by the stop means 135, 136, the accurate adjustment of the forward terminus of travel of the punch 17 by the extension arm 170 and the lower stop element 174, and the yieldable mounting of the anvil plate 56 afforded by the cushion ring 57, allow the severed film sections 14 to be pressed against the borders 12 of the cards 10 without danger of damaging said film sections, said borders or any elementsof the apparatus. After the film section 14 has been thus mounted in the card It), the handle 161 is released, whereupon the spring 169 restores the parts to the starting positions thereof shown in FIG. 4, determined by engagement of the extension arm 170 with the upper stop element 172. Retraction of the punch 17 to its original position releases the card 10 with the film. section 14 mounted therein, and also releases the guides 175 and 176 for return movement by the springs 182 to their inner film strip receiving and guiding positions. Following the removal of the film mounted card 10 from the apparatus, the film strip 15 is again advanced to position the next image thereon in registry with the dies 16 and 17, a new card 10 is inserted into the apparatus, an the above described operations are repeated.
