To all who/m it may concern:

Be it known that I, CHARLES H. CADIEU, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Mount-Trimming Machines, of which the following is a specication. Referring to the accompanying drawings: Figure 1 is a front elevation of my improved mount trimming machine. Fig. 2 is a plan view of the machine shown in Fig. 1. -Fig 3 is an end elevation of the masection on line 4--4 of Fig. 1. Fig. 5 is a front view partly in section and partly in elevaton of the parts shown in Fig. 4. Fig. 6 is a sectional view of one of the cutters and its support. Figs. 7 and Sare details hereinafter described.

Machines for trimming photograph mounts have, as heretofore constructed, been objectionable in that the mounts were bent by a presser-belt around a rotating drum while being trimmedl which not only setthe mounts in a curved shape, but also acted to crimp each mount upon the interior of the bend and to stretch and crack it upon the exterior of the bend. Moreover, such machines, so far as I know, have only been capable of operating upon single ply or card mounts upon which the photographs are pasted, and could not be used as a practical matter, upon two ply mounts comprising a back sheet and a mat pasted together around their edges and between which the photograph or photographs are inserted, mainly because the usual opening or openings made in the mat so weaken that sheet or ply that the mount cannot be bent as is necessary in such machines without breaking the mat.

The object of my invention is to provide v an improved trimming machine which will operate upon any kind of photograph mount, especially two ply mounts, without injury to the latter, and also to provide a machine of this kind which may be used to trim mounts of any ordinary size.

My improved mount trimming machine comprises a cutter for trimming the side of the mount, and a pair of driven rolls which feed the mounts past the cutter without bending them and also serve to support and hold the mounts at the point where the cutter acts thereon while the mount is being frame of the machine. chine shown 1n Figs. 1 and 2. Fig. 4 is a l* trimmed. In the best form of my invention the mounts are automatically fed one at a time to the feed rolls above referred to from a hopper within which a pile of untriinined mounts .is placed.

Other features of my invention are hereinafter pointed out.

A pile of mounts to be trimmed is placed within a hopper consisting of two plates 1, 1 each integral with and projecting from a block 2 having a hook 3 engaging the upper edge of a. cross-bar 4 forming part of the The bar 4 is made with a lengthwise slot 5 to receive blocks 6 that are tapped to receive the inner ends of screws 7 by which the blocks 2 are clamped in tlxed positions on bar 4 with the plates 1 separated a distance equal to the width of l the mounts that are to be trimmed. Along its lower edge each plate 1 is made with an inwardly projecting lip 8 which extends under and supports one side of the pile of mounts, while at its front or inner upright edge plate 1 is made with an inwardly projeeting lip 9 extending from the top of the plate to a point just above the inner end of the lip 8 so as to leave a passageway be.- tween the two lips, see Fig. 4, through which the lowermost mount is fed to the trimming mechanism by a reciprocating feed slide 10. The slide 10 is made on its under side with a lengthwise dovetail slot to receive a dovetailed arm 11 projecting from a plate 12 secured by bolts 14 to a cross-bar 13 forniing part of the frame of the machine. The bolts 14 extend through a slot 15 extending lengthwise of the cross-bar 13 so that when the plates 1 are adjusted, the plate 12, arm 11, and slide 10 can be shifted so as to occupy a central position between the two plates 1 however the latter may be placed. llhe slide 10 is connected by a rod 16 with an eccentric 17 fast to one end of a sleeve 1Ta splined to a shaft 18. The sleeve 17 extends through the arm 11 and has fastened to its other end a collar 17b so that when arm 11 and slide 10 are shifted as described above, the eccentric 17 is moved with them.

Fixed to one end of shaft 18 is a gear 19 driven through an idler 20 by a gear 21 fixed to a shaft The shaft Q2 carries a pulley driven through a belt 24 by a pulley Q5 iixed to the main shaft 2G of the machine which is provided with fast and loose pulleys 26a and 2Gb. Through the mechanism just described the slide 10 is reciprocated beneath the pile of mounts, said pile being held against forward displacement by the lips 9 in front of the pile and against rearward displacement by two plates 27 at the rear of the pile. Each plate 27 is secured to the inner face of its plate 1 by a screw 28 extending through a slot 29 in an arm 30 project-ing rearwardly from the plate 27. On its top side the slide 10 is made with a lengthwise groove 31 to receive a block 32 fixed in place by a screw 33 extending tlnough a slot 34 in said block 32. To the top of block 32 is fixed a thin cross-bar 35 which is above the top surface of slide l() so as to constitute a shoulder for engaging the rear end of the lowermost mount of the pile to shove the latter forward through the passageways between the adjacent ends of the two pairs of lips 8- and 9 between two pairs of feed rolls 36 and 37 which are part of the trimming mechanism. The rolls 36 are fixed to the shaft 22 with provision for adjustment lengthwise thereof by screws 38 so that they may be positioned to accord with the adjustment of plates 1. For the saine reason the rolls 37 are fixed to a shaft 39 with provision for adjustment lengthwise vthereof by screws 40.

Fixed to one end of the shaft 22 is a gear 41 which drives a gear 42 fixed to the shaft 39 of the upper rolls 37. The shaft- 39 is journaled in blocks 43 free to slide vertically in slots 44 in the frame of the machine. Each block 43 has fastened to it the lower end of a threaded rod 45 which extends upwardly through an extension 46 of the bar 4 and carries at its upper end a nut 47. These two nuts 47 limit the approach of rolls 37 to the rolls 36. Between the blocks 43 and the extension 46 are interposed coiled springs 48 which serve to exert a yielding downward pressure on the rolls 37. Each time the slide 10 moves forward it feeds the lowermost mount forward out of the hopper and between the two pairs of rolls 36 and 37, and the latter, which are driven in the direction of the arrows, Eig. 4, propel the mount forward as its sides are trimmed by a` pair of opposed cutters 49 and discharge the trimmed mount upon an endless traveling apron 50. The apron 50 is mounted upon two drums 51 and 52, the latter being fixed to a shaft 53 carrying a pulley 54 driven through a belt 55 by a pulley 56 fixed to main shaft 26. A suitable receptacle may be provided at the lower end of the apron 50 to receive the mounts discharged therefrom. Each cut-ter 49 is fixed to the lower end of a spindle 57 journaled in ay yoke 58 having a stem 59 clamped in a split socket 60 by a screw 60a. The socket 60 is made with a stem 61 clamped in the lower end of a split sleeve 62 by a screw 62a, said sleeve being interiorly threaded at its upper end to receivea threaded stud 63 projecting downwardly from ablock 64. The block 64 at its upper end is made with a tongue 65 projecting into a slot 66 formed in cross-bar 4 parallel with slot 5, and with a threaded stud 65a to receive a nut 67 by means of which block 64 is clamped in fixed position. It will thus he seen that each cutter 49 is carried by a holder that may be adjusted toward and from each other on the frame of the inachine when the positions of the rolls 36 and 37 are changed.

The upper end of each spindle 57 carries a collar 68 against which bears a spring 70 arranged within a chamber 71 provided in yoke 58. The purpose of this spring is to yieldingly press the cutterl 49 against the corner of the roll 36 with which it cooperates. To each spindle 57 is splined a pulley 72 continuously driven through Va belt 73 by a pulley 74 fixed by a screw 75 to a shaft 76 so as to be adjustable lengthwise of the latter. The sha-ft 76 carries at one end a pulley 77 driven through a belt 78 by a pulley 79 fixed to main shaft 26.

The stem of each yoke 58 is made hollow and interiorly threaded to receive the inner the socket 60, the outer end of said screw belend of an adjusting screw 80 swiveled in 5 ing squared to receive a wrench by means of which the screw is operated. By loosening screw 60a and operating screw 8O the cutter 49 can be accurately positioned relatively to a line passing through the centers of both rolls 36 and 37 whereat the mounts are most firmly held by the two rolls while the cutters 49, driven in the direction indicated by the arrow in F ig. 4, trim the opposite edges of the mount. Each cutter 49 is held against swinging bodily on the axis of sleeve 62 by a check nut 81 on stud 63, but by loosening this check nut the cutter may be thus bodily shifted to adjust it relatively to roll 36. The stud 63 is made hollow and interiorly threaded to receive the upper threaded end of a screw 82 swiveled in stem 61, and the lower exterior end of this screw 82 is squared to receive a wrench by means of which it is operated to adjust stem 61 vertically when screw 62a is loosened. In order to prevent relative rotary movement between sleeve 62 and stem 61 said sleeve carries a pin or screw 83 projecting into a lengthwise groove 84 provided in stem 61. From the above it will now be clear that the cutters 49 besides being bodily adjustable to accommodate changes in the positions of the rolls 36 and 37 are also universally adjustable so as to be accurately positioned with relation to the rolls 36 and so that the angle at which the edge of the mount is trimmed may be varied at will.

Since the cutting stroke of each cutter 49 is upward, it is necessary, in order to secure the cutter.

a clean cut, that the upper rolls 37 bear upon the mount very close to the cutter, and for this reason the upper rolls 37 are each made with a flange 37a extending toward Of course when the cutters 49 are set to cut an unbeveled or perpendicular edge which, however, is seldom the case with photograph mounts, then the roll 37 can be set close to if not in Contact with the cutter 49 but when the cutters 49 are set at an angle to produce a beveled edge on the mount as shown in the drawings, then the rolls 37 may be set so that the flange 37 a extends under the cutter as shown in Fig. 5, and closer to the point of cutting than it `would be possible to place a solid roll, the

space within the flange 37"* serving as a recess into which the cutter 49 can project. Alongside of each cutter 49 is provided a cutter grinding wheel 85 fixed to one end of a spindle 86 journaled in a yoke 87. The other end of spindle 86 carries a collar 88 engaged by a spring 89 which normally holds wheel 85 out of engagement with cutter 49. The spring89 is arranged within a hollow boss 90 which is interiorly threaded to receive a. nut 91 against which the end of spindle 86 is held by spring 89. lVhen it is desired to sharpen the cutter 49 the operator screws nut 91 inwardly while the cutter is in operation, thereby shifting the spindle 86 endwise and carrying wheel 85 against the cutter. rlhe yoke 87 is made with a stem 92 clamped by a screw 93 within a split sleeve 94. This sleeve 94 is made with a stem perpendicular to stem 92 and clamped in a split sleeve 96 by a screw 97. The sleeve 96 is made with a stem 98 clamped within a split socket 99 by a screw 100. The socket 99 is part of a bracket 101 made also with a tongue 102 projecting into a slot 103 provided in a cross-bar 104 forming part. of tl e frame of the machine. The bracket 101 is clamped to bar 104 by a screw 105 and as will be clear, by loosening this screw the bracket 101 and grinder wheel carried thereby may be shifted bodily when the cutters and rolls are shifted. lt will also be clear that the support for each grinder roll provides for universal adjustment of the latter to adapt it to any position of the cutter 49 with which it cooperates.

0n each spindle 86 is splined a pulley 106 driven through a belt 107 by a pulley 108 fastened to a shaft 109 with provision for adjustment lengthwise of the latter, by a screw 110. rThe shaft 1.09 carries at one end a pulley 111 driven through a belt 112 by a pulley 113 fast to the main shaft 26.

The hub of each pulley 74 and 108 has loosely pivoted on it, as shown in Figs. 7 and 8, a lever 114 carrying at one end a pulley 115 and at its other end an adjustable weight 116, said lever, weight and pulley constituting a belt tightener which maintains a proper tension in the belt of the pulley, on whose hub the lever is pivoted. The belts 73 and 107 are longer than the distance between pulleys 106 and 108 or pulleys 72 and 74 so that the cutters and grinders are free to be adjusted on their hold may be required and at the same time the belt tighteners just described automatically keep the belts under proper working tension whatever that adjustment may be. When the cutter-holders and grinder-holders are shifted on the frame of the machine in adapting vthe latter to operate on mounts of another size, then it is only necessary for the operator to shift the pulleys 74 and 108 on their shafts, the belt tighteners being carried by the hubs of those pulleys do not require the attention of the operator.

Long mounts take a longer time to pass through the rolls 36 and 37 than do shorter mounts and since it is desirable and most economical to have the blanks both long and short follow one another as close as possible out of the hopper 1, 1 to the trimming mechanism, I have herein provided for regulating the speed of operation of feed slide 10 according to the length of the mount being operated upon so that said slide may be operated at a relativelyy faster speed when short mounts are being trimmed and at a relatively slower speed when long mounts are being operated upon. To this end the idler 20 is mounted on a stud 20EL projecting from a frame 20b that is pivotally hung upon the shaft 22. rlhe frame 20" is locked to the main frame of the machine with idler 20 in mesh with gear 19 by a screw 20C eX- tending through a slot 20d in said frame 201. lVhen mounts of another length are to be operated upon the screw 2OC is loosened and idler 20 lowered and gear 19 replaced by a gear of another size appropriate to the speed desired for feed shaft 18. The frame 20b is then swung back and clamped in position by screw 20C. At the same time the operator adjusts the block 32 on slide 10 to correspond with the changed position of the rear or outer edge of the pile of mounts, shifting said block inwardly on 'slide 10 if shorter mounts are to be operated upon and outwardly if longer mounts are to be operated upon. Of course the plates 27 will at the same time be correspondingly adjusted.

The tongue 66 of the block 64 which is part of the holder of the cutter at the right of the machine, Fig. 1, is made with a transverse threaded aperture througli which extends the inner end of a screw 117 journaled near its outer end in the cross-bar 4. At its outer end the screw 117 carries a crank handle 118 through which said screw is rotated to shift the right hand holder toward and from the other or left hand cutter holder when the nut 67 is loosened.

As the mounts emerge from the rolls 36 and 37 they pass onto guides 119 fastened to the bar 104 with provision for adjustment lengthwise thereof, and from said `guides they fall upon the apron 50.

The most convenient arrangement of )arts is to have one pair of rolls 36 and 3 its cutter, grinder and guide, permanently located at the limit of its outward adjustment as shown at the top of Fig. 2, and to adjust only the slide 10 and the other pair of rolls 36 and 37 with the latters complementary mechanism when altering the machine to ada-pt it to mount-s of another width.

From the above description it will be seen that I have provided a machine which will accurately and uniformly tri-m and bevel the edges of photographic mounts of any ordinary width and length without in any `way marring or injuring the latter, and

which is particularly adapted to operate upon mounts made of two pieces of material pasted together.

The main feature of my improved ma-V chine is that the engagement of each cutter and its feed rolls with the mount is, in effect, concentered at the same point on the latter so that the rolls not only feed the mountpast the cutter and hold said mount `in proper position to be operated upon by the cutter, but they also prevent the cutting thrust or pressure of the cutter from bending the mounts.
