Filed July 13, 1959, Ser. No. 826,693 4 Claims. (Cl. 93-1) The present invention relates to photographic mounts and particularly relates to photographic mounts which may be utilized for holding transparency or other photographic elements in position for projection or observation purposes.

It is among the objects of the present invention to provide a novel continuous system for manufacturing foldable photographic mounts at a high speed of production at low cost and with assurance that such mounts will be produced with uniformity and with means thereon to correctly locate and fix the position of the photographic element or transparency.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.

In accomplishing the above objects a strip of cardboard is first trimmed to proper size and then is passed between a serrating or scoring roller which will fix a central fold line longitudinally along the axis of the strip, and the strip is then provided with two shear lines on a base folded on one side of the folder with several interrupted shear lines at one side and extending between the longitudinal shear lines.

In the final operation after the various shear lines have been formed on one side of the folder, the windows are die-cut so they will match and this will form a recess or receptacle within which a transparency may be slid with assurance that there will be correct register.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views.

FIG. 7 is a bottom plan view taken from the line 77 of FIG. 5, showing the shearing blades from below and upon an enlarged scale as compared to FIGS. 5 and 6.

3,115,657 Patented Jan. 7, 1364 FIG. 8 is a perspective plan view of the final foldable supply mount with the sheared portions on the sides thereof and on one of the folds of the folder, and upon an enlarged scale as compared to FIGS. 1 to 6.

FIG. 9 is a transverse sectional view taken upon the line 9 of FIG. 8, showing in perspective the effect of the longitudinal shearing accomplished by the apparatus of FIGS. 5 to 7.

FIG. 10 is a fragmentary top perspective view of the upper lefthand portion of the flat folder of FIG. 8, showing the position of the transparency when inserted therein and when fixed in position in respect to the window.

FIG. 11 is a transverse sectional view upon the line llll of FIG. 8, showing the interrupted shear line.

Referring to FIGS. 8 to 10 there is shown a photographic mount A consisting of an upper window foldable section B connected by the fold line C to a lower foldable window section D.

As shown by C there will be a series of closely spaced perforations or score marks resulting, as is best illustrated in FIGS. 8 and 10.

The upper section B has a die-cut window E which matches the die-cut window F in the lower section D. The lower section D carries the longitudinal partial shear portions G and H which locate two opposite sides K of the transparency I.

The other edge L of the transparency I abuts the interrupted shear line M, N and P.

Referring to FIGS. 1 and 2, there is shown the successive operations and machine structures at Q in FIGS. 1 to 3 for forming the central score line C, the oblique rotary shearing between the circular knives R for forming the longitudinal partial shear portions G and H and the transverse interrupted through shearing arrangement S for forming the interrupted shear members M, N and P, and finally the window shears T for forming the windows F and E, with the final shear U for cutting the folders one from the other.

Referring first to the division for forming the score line, it consists of a fixed or rotatable wheel which is pressed down upon the serrated tor ridged roller Y, which may also rotate. Desirably the roller X is held fixed and has a sharp edge 20 (see FIG. 3), which is carried on the shaft 21 having the stepped-down portion 22.

The shaft is held in a sleeve 23 between set screws 24, and it has an end knob 25 held in position by the set screw 26. The wheel or edge roller will be held in position on the reduced end portion 2 by the washer 27 and the bolt 28.

The arm 29 (see FIGS. 1 land 2) is attached to the knob 25, and it will press the edge 29 against the strip of paper Z, which has been previously trimmed and which is being fed into the successive mechanisms Q, R, S, T and U.

The strip Z will pass over the base plate 30 and under the spring fingers 31. Between the spring fingers 31 is a slot 32 where the longitudinal fold line C will be formed by the sharp edge 29 of the roller X.

The plate 3-9, with its side guide members 33, may be adjusted back and forth by the screw 34, having the handle 35.

The handle 35 will adjust the plate 34 so that the edge 20 is directly along the longitudinal axis and can press such axis down against the serrated or ridged roller Y, having the ridges or serrations 36. The ridge roller Y may turn while the edge roller may stand still in the preferred construction.

The ridge roller Y is held on the shaft 37, which is mounted in the carrier portion 38, held in position by the nuts 39 and 4d. The bolts 41, fitting in the slot 42, will limit the amount of adjustment of the plate 3i) and the side guides 33.

From the center scoring C the strip passes to the partial oblique shearing operation at R, Where it is subjected from the lower side to the obliquely positioned beveled wheels 50.

These wheels are mounted by the washers 50 and the bolts 52 upon the post members 53, which are adjustable through the openings 54 in the blocks 55. The position may be set and then fixed by the set screws 56. The blocks 55 in turn are mounted upon the transverse shaft57 between the side standards 58, which are mounted by the inturned flanges 59 and the bolts 60 upon the base 61.

The bar or rod 57 is flatted as indicated 62 in FIG. 5, and the set screws 63 will position the blocks 55 in the desired position.

The shear wheels 50, having the bevelled cutting edges 70, as shown in FIG. 7, are set at an oblique angle 71 (see FIG. 7) in respect to the direction of movement '72 to form the partial shear portions G and H, as shown in FIGS. 7, 8, 9 and 10.

It will be noted that there is a thin upturned edge 73 formed in FIG. 9, with a sloping inward cut portion '74 which acts both to stop the edges K of the transparency, as shown in FIG. 10, and also to lock it in position if need be by the resiliency of the upturned edge 73, which tends to press the two contacting edges K of the transparency J toward one another.

The cutting wheels project upwardly through the opening 75 in the table portion 76, as indicated in FIG. 6, with the side guide plates 77 constituting a continuation of the side guides 33 shown in FIG. 3.

The paper strip Z is pressed down against the oblique cutting edges 70 by means of the rollers 78, which are held by the shaft 79 in the blocks 80, which in turn are pivotally mounted by the shaft 81.

The cross bar 82 carries the adjusting threaded rods 83, having the knurled hand turning members 84, which are locked in position by the lock nuts 85.

The lower end of the threaded rods at 86 act upon the top face 87 of the blocks to press the rollers 78 against the strip Z and against the oblique edges 76) of said partial shearing rollers. The entire apparatus is mounted on the block member 83, which is carried on the shaft 81.

In respect to the interrupted shearing mechanism S, window shearing mechanism T and the cut-off mechanism U, these are mounted, as indicated in small scale in FIGS. 1 and 2 and in large scale perspective in FIG. 4, on the block 1%.

The block 190 has the end pivot blocks 101 carrying the transverse shaft 102, which has an upwardly extending connecting member 193. The connecting member 103 has the adjustable connection 104 to the oscillating or reciprocating member 105 on the crank 106.

The block 100 at its forward end carries the Z member 107 having the interrupted shearing blades 108, which are carried upon the downwardly projecting member 109 (see FIG. 2).

These blades will form the through shear cuts M, N and P, as indicated in FIGS. 8, l0 and 11.

Intermediate of the block are mounted the two block dies 110 which form the window shears T. These window shears T cooperate with the base block 111 having corresponding window shear openings 112.

The final shear blade 113, forming part of the mechanism U, will cut off the photographic mounts one after another as indicated at 114, 115 and 116 and discharge them down a slide 117.

The blade is mounted upon a L member 118 held in position between the top flange 119 and the adjusting screw 120;

Referring to FIG. 4, it will be noted that the interrupted shear blade 108, which is mounted in position by the screws 122, has three separated teeth 121, which will operate in conjunction with the openings 123 in the base plate 124 to enable a through shear cut, as indicated in 4 FIG. 11 at N, with one side of the shear cut and corresponding bevel of the shear teeth 121 being fixed upwardly, as indicated at 125, which will act as a stop, as indicated at the edge L of the transparency in FIG. 10.

This entire apparatus will operate at a high speed to centrally score, partially shear and then interruptcdly transverse, shear and finally die-cut the windows E and F and separate the mounts of FIG. 8 one after another.
