'8 CLINTON F. BRUNDAGE F5 -4 MM ATTO United States Patent Ofiee 3,059,691 Patented Oct. 23, 1962 3,059,691 APPARATUS FR MOUNTING INSERTS Clinton F. Brundage, Mahwah, NJ., assignor to Minnesota Mining and Manufacturing Company, St. Paul, Minn., a corporation of Delaware Filed Dec.. 7, 1959, Ser. No. 857,572 12 Claims. (Cl. 156-530) This invention relates to apparatus for mounting sections of films to record cards and more particularly to apparatus for severing a section of lm from a strip of film and mounting the same in an aperture in a record card.

Many of the present day business machines utilize record cards wherein information is stored on the cards either by a series of punched holes or by magnetic material selectively space-d thereon. It has been found useful to combine visual information on such cards in the form of lm or other photographic representations. Such a card structure is shown in the U.S. patent issued to Langen, No. 2,587,022. These cards are produced in large quantities by machines such as shown in the U.S. patent issued to Standish, No. 2,666,543. There are many instances, however, where it is desired to prepare only one card at a time. This invention is directed to such an apparatus.

One object of this invention is to provide an apparatus for severing a section of film and mounting the severed portion in an aperture of a card which is simple in construction and light in weight.

Another object is to provide an apparatus of the above character wherein the dies are of a novel construction.

Another object is to provide an apparatus of the above character having a novel card supporting structure.

A still further object is to provide an apparatus of the above character having a novel film strip holding means.

The above and further objects and novel features of the present invention will more fully appear from the followdetailed description when the same is read in connection with the 4accompanying 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.

iIn the drawings wherein like reference characters refer to like parts throughout the several views,

FIG. l is a top plan view;

FIG. 2 is an end elevational view taken along the line 2-2 of FG. l;

FIG. 3 is a side elevational view taken along line 3-3 of FIG. l; and

FIG. 4 is a side elevational View taken along line 4 4 of FIG. 1.

Referring now to the drawings, there is shown in FIGS. 1 and 2 a base 1t) supported at each corner by suitable legs. A pair of lower cutting blades 11 and 12 extend across the upper surface of base and are spaced apart a distance substantially equal to the width of the upper cutting blade 13. A spacer plate 14 having a thickness substantially equal to the thickness of a card 15, to which a iilm section 16 is secured, is positioned beneath the rear portion of each blade. -In this manner the forward portions of the blades are spaced from the base 10 and from a card receiving slot 17. The rear section of blade `11 is secured to `base 10 in any suitable manner such as by bolts. Blade 12 is pivotally mounted to base 10 by the eccentric adjustment 18. A blade spacer 19 having a length slightly less than the wide of upper blade 13 is positioned between the forward ends of the blades. An aperture extends through said spacer and through the forward end of blade 11. A pin 20 is secured at one end to the forward end of blade 12 and extends through the apertures and beyond blade 11. A spring 21 is telescopically mounted over the extending end of the pin and is held in a compressed condition between blade 11 and a transversely extending pin in the end of pin 20. Spring 21 through pin 20 constantly pulls the forward end of Iblade 12 toward blade 11 and spacer 19. Upper blade 13 is pivotally mounted at its rear end by a transversely extending pin, the ends of which are mounted in the sides of blades 11 and 12. A spring 22 has one end secured to the undersurface of base 10 andthe other end secured to the end of blade 13 so that the blade is constantly urged into an upwardly extending position. The blade 13 at its pivot point is always positioned between blades 11 and 12. By adjustment of the eccentric pivot point blade 12 can be moved toward blade 11 thereby moving

blades

11, 12, and 13 together so that there is always a tight fit between cutting surfaces of these blades. As blade 13 is lowered it will gradually push the forward end of blade 12 away from blade 11 about the pivot point 1S so that there is a constant tension on the cutting edges between blade 13 and blades 11 and 12 during the downward stroke of blade 13. Blade 12 is retained from vertical movement by a spring clamp 25 which is secured to base 10 by a pair of bolts which pass through slotted openings in blade 12 and through apertures in clamp 25. Each bolt has an enlarged head to prevent it from passing through the apertures in clamp 25. Each lbolt also has a spring member telescopically mounted over the bolt and are compressed between clamp 25 and the upper surface of blade 12.

A plate 26 is secured to the upper surface of base 10 adjacent an edge of blade 11 and has its upper surface ilush with the upper surface of blade 11. The edge of plate 26 serves as a stop for the forward end of card slot 17. A plate 27 is `secured to the base 10 and adjacent the slot 17 and one edge of the plate serves as a guide for one longitudinal edge of a card inserted in the slot. Another card guide 28 having a surface positioned in operational alignment with the card guide edge of plate 27 and comprising -a right angle plate is secured to the underside of base 1t) and extending upwardly through a slot in said base. Guide 28 is secured in such a manner that it will be depressed into the slot upon the lowering of blade 13. Both

card guides

27 and 28 are secured to jbase 10 in such a manner as to permit them to be adjusted toward or away from the card slot 17. A film guide 30 is secured to the top surfaces of blades 11 and plate 26 and extends in a parallel horizontal plane with the card slot 17.

A film clamp 31 is mounted to the top surface of blade 12 and in horizontal alignment with the lm guide 30. The iilm clamp comprises a lever 32, having a head 33, which is pivotally mounted on a shaft 34 which extends through the lever and has its ends rotatably mounted in blocks 35 on each side thereof. A resilient rod 36 has one end passing through the rear portion of lever 32 and its other end secured to the surface of base 10. Rod 36 constantly urges the head 33 of clamp 31 into contact with the upper surface of blade 12. This clamp serves to hold the last frame of a strip of film in proper position for severing the portion thereof carrying the image.

A recessed area 40 in the upper surface of base 10 is positioned in relation to the card plate 26 and guide 28 so that the apertured portion of card 15 will be in registry with said recess. A pressure pad 41 is pivotally mounted in said recess at the pivot point 42. The pivot point 42 is the end of a bolt which is threadedly mounted to the base 10 so that by turning the bolt the pressure pad can be lowered or raised to effect the most satisfactory contact for a card and lm section as it is compressed between blade 13 and pressure pad.

A card retaining member is mounted at one corner of card slot 17 and comprises an aperture in the base 10 and a ball 43 positioned therein. A leaf spring 44 overlies one end of the ball 43 and is secured at its other end to base 10. Ball 43 is constantly urged upwardly against the blade 11.

In operation a card having an aperture and an adhesive marginal area extending into said aperture is inserted into slot 17 with the adhesive surface `facing upwardly. One edge of the card is aligned into contact with the

guides

27 and 28 and the end of the card abuts the end of plate 26. At the same time one corner of the card is inserted between ball 43 and the undersurface of blade 11 so that the card is frictionally retained in slot 17. A strip of film is unwound from a roll of film (not shown) and fed through film guide 30 until the desired portion of the film extends between blades 11 and 12 and the very `forward end of the strip is gripped between head portion 33 of film clamp 31 and the upper surface of blade 12. The blade 13 is then manually lowered until it is pressing against the pressure pad thereby severing the section of film and moving it into Contact with the adhesive sheet in the card aperture.
