Application filed October 27, 1909. Serial No. 524,917.

To all whom it may concern:

Be it known that l, Jorilv J. Srmrnn, a citizen of the United States, residing at Lenox, in the county of Macomb and State of lvlichigan, have invented a new and useful Photographic Printing Machine, of which the following is a specification.

This invention is a photograph printing machine and the object of the invention is to provide a simple and etlicient device by which post cards may be rapidly fed from a hopper to a proper position in contact with the negative and discharged from the said position after being printed.

The invention seeks to provide a machine of this pharacter in which the operations of feeding the card to the negative and discharging the same therefrom will be performed automatically upon the manipulation of a single lever carrying the presser plate by which the post card is held in position against the negative during printing. This and other objects are attained in the apparatus illustrated in the acco-n'ipanying drawings which illustrate one embodiment of the invention, all of which will be hereinafter first fully described and the novel features of which will be subsequently pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of the front side of the device. Fig. 2 is a similar view of the rear side of the same. Fig. is a longitudinal section on the line 33 of Fig. 2. F iis a transverse section taken on the lines H of Figs. 1 and 2. F 5 is a longitudinal section taken on the line of 2. Fig. 6 is a transverse section on the line 6 -6 of Fig. 9. F ig. 7 is a perspective view looking at the under side of the slide. Fig. 8 is a detail perspective view of one of the trips on the ward-feeding slide, Fig. 9 is a detail sectional view taken through the negative holding compartment, showing an amplification. F 10 is a detail elevation partly in section showing a modification of the means for applying pressure to the cards within the hopper.

In carrying out my invention, I employ a face plate 1 and a back plate 2 which is spaced from the face plate and connected thereto by the plates or beams 23, as shown. When the device is in use, it is set up in an inclined position, as shown in Fig. 4, and may be secured in that position by any means most convenient to the operator. The face plate and back plate are provided with registering openings at and 5 near their lower edges when so set up and at about the center of the same and the negative 6 is supported in alinement with these openings between the same upon cleats or similar devices provided for that purpose upon intermediate beams or sills 7. Upon the face plate, at the sides of the opening 5, are adjustably secured the guiding plates or blocks 8 by means of set screws 9 inserted through transverse slots 10 therein and provided with thumb nuts 11 by means of which they may be secured in proper position to accurately center a postcard over the negative. The upper ends of these guide. blocks 8 are inclined or flared, as indicated at 12, so that the post-card which may be delivered from the hopper will be thereby guided toward the opening 5 in the face plate and consequently be caused to ac curately drop upon the negative and into contact therewith. Above the said guide plates and slightly to one side of the same is provided a hopper 13 within which the post-cards are placed, and at the base of the said hopper, upon the face plate, are guides 14 in which a slide 15 is mounted in position to move across the back of the hopper and remove from the same the rearmost postcard which will be thereby carried to a position beyond the side of the hopper and will then drop between the guide plates 8 and onto the negative. In order to maintain the cards in the proper position within the hopper and prevent them from twisting therein so that they will not feed easily and smoothly, I provide a follower 16 which rests upon the cards and from which a threaded stem or standard 17 rises, a nut 18 being mounted on the said threaded stem or standard, as clearly shown. @n the side of the hopper I provide brackets 19 between the outer ends of which a presser arm 20 is pivoted, one end of said arm projecting over the hopper and provided with an opening through which the threaded stem or standard 17 plays. This end of the presser arn 20 will at times bear upon the nut or collar 18 and thereby exert a pressure upon the cards which will permit the slide to easily and accurately engage the proper card and feed the samefrom the hopper, it being understood that as the supply of cards diminishes the nut or collar 18 will be adjusted toward the upper end of the stem or standard 17 and consequently will always be in position to be engaged by the end of the presser arm while at the same time the tollower 16 may remain in contact with the uppermost card. The arm is held normally toward the nut or collar 18 by a spring 21 which is secured to the said arm and the side of the hopper, as snown in Fig. 3, and as will be readily understood. The oppo site end of the presser arm has secured thereto a link or pitman 22 which passes thence through an opening in the face plate and has its lower end attached to a spring dog Z C fulcrumed on the under side of the face plate near one corner of the same, as indicated at 25, the outer end of the said dog being held normally toward the adjacent edge of the face plate by a spring 26 so that the inner end of the said dog, to which the link or pitman 22 is attached, will be held normally over a slide 27 mounted on the under side of the face plate, as will be presently more fully described.

The operating lever or handle 28 is tulcrumed at one end upon the front of the face plate in such position as to extend across the negative-receiving opening, and the presser plate 29 is carried by the said lever or handle through an intermediate or supplemental arm 30 held to the operating lever by a loop or bracket 31. Near its free end on its under side, this operating lever or handle carries a block 32- which, when the handle is in its lowest position, will rest upon a pin 33 mounted vertically in the face plate and having its lower end pivoted to one arm of a bell crank lever 34, the other arm of which is connected by a connecting rod 35 with a shutter 36 hinged within the negative receiving compartment by a spring hinge 37. It will be seen at once that when the lever is lowered so as to actuate the pin 33 the shutter 36 will be opened through the action of the bell crank lever 34L and the connecting rod 35 so that light may pass through the negative to the post-card held in contact with the same, and that upon the lifting of the lever the shutter will be immediately closed through the action of the spring hinge 37. The peculiar manner of supporting the presser plate permits the operating lever or handle to act upon the same somewhat in the nature of a spring so that the necessary force may be exerted upon the post-card to hold the same in smooth intimate contact with the negative without the plate being pressed against the negative with such force as to break the negative. In order to hold the lever against the card with the force necessary, I provide the loop 38 on the base plate adjacent to the pin 33 so that when the lever is lowered, the free end of the same will lie immediately over and upon the said loop which may then be grasped by the operator so that in order to prevent undue loosening of the card from the negative it is only necessary to hold the end of the lever closely against the said loop, as will be readily understood.

At its t'ulcrumed end, the operating lever is provided with a depending finger 39 which extends through a slot tO in the face plate and forms one arm of an angle plate, the other arm ell of which is secured to the under side of the lever. The fulcrum pin 42 passes through the angle plate at the bend of the same and has its ends fitted in brackets or lugs 43 on the front of the taco plate at the sides of the slot 10, as clearly shown, and as will be readily understood upon reference to Figs. 1 and 3. The lower end of the finger 39 is pivoted to one end of a link 44 which has its opposite end pivoted to a rock lever a5 tulcrumed upon the under side of the face plate and having its upper end pivoted to the slide 27 hcreinbefore mentioned. This slide 27 extends across and below the opening 46 formed in the face plate to register with the lower end of the hopper l3 and is provided on its back. near that end to which the lever lf; is pi voted, with three ribs 47, 4L8 and The upper rib l7 has its end. adjacent the end ot the slide, standing substantially at a right angle to the Face (it the slide in position to engage the beveled edge 30 on the head 5t of the spring dog so that when the slide is drawn toward the right in l ig. 2 the said abrupt end of the rib 4? will turn the dog Qlon its pivot '27). but when the slide is moved in the opposite direction the inclined end of the rib 47 will bear against the side of the head 51 and thereby spring the dog away from plate 1. This will cause the dog to ride behind the rib and consequently exert a rearward pull upon the link 22 and thereby raise the presser arm '20 from its engagement with the nut or collar 13 and consequently relieve the pre sure tram the cards within the hopper 13. The intermediate rib -18 serves as a stop to limit the pivotal movement of the dog under the influence of the spring 20. and also serves to limit the movement of a spring lever tulcrumed upon the base plate at the opposite side 01 the slide 2? and held normally upward toward the rib 4 3 by a spring 53. a will be readily understood. The tree end ot this lever is provided with a head 5 arranged in position to engage and ride upon the lower rib 4-9 and extending over the upper end of a lever tulcrinned upon a suitable bracket 56 on the inner side oi the face plate and having its lower end pivoted to a crank arm 57 on one end of a rock shaft 58 which is jonrnaled upon the base plate near the lower edge of the same and has a similar crank arm at its opposite end. spring (:0 coiled around the said rock shatt and attached to the same at one end and at its opposite end to one of the bearings off the the t normally against the w The free ends of the crank arms 5'? 3'? are connected by links 5 5 thr ugh the Tilt-Ct: plate, to a hail or card rest l the i s t which are 7 i. out side ot the ice plate so tha the e t: t hail t.

Il pin is carried by a sinal plate 65 hole to the slide by a keeper (3' and having a slight sliding nmvenien through the said keeper (see Fig. '2'). ll 1- plate (36 is disposed at about the center o the slide and has t e/pending train it; under surface a pair at pins (it) Which pass on opposite sides of a rod 9 connecting a pair of dogs 70 which extend through tl slide and are provided at the r" upper end." with h adapted to engage the sinall tee h ll under side of the postcard and ther by positively feed the same to the negat ve in the operation of the vlile. in the t'orin of the invention illustrated the tooth "Z1 anpears as a small thin plate securzd to the side of the dog: but it will be understood, of course. that this exact construction is not essential. The plate 66 is limited in its movement in one direction by a fixed stop 72 secured to the under side of the slide 15, and. in the opposite direction by a inovable stop 73 which pivoted to the under side of the slide 15 and has its free end projecting beyond the edge oi the same, as shown most clearly in T. lVhen the movable stop is turned into position to engage the end of the plate (36, the said plate will be held innnovably between the said movable stop and the fixed stop ?2 so that movement of the dogs '70 will be prevented. Should the stop however, be turned out of the path of the plate 66 the dogs may have a slight movement, and this movement will be effected by a" trip 74- Which is mounted loosely on the pin and rests upon the slide 27. The free end of the trip is bent into position to ride against a stop or bracket T5 on the inner side of the face plate, the said i racket serving; also a support to hold the slide 2'? against the tace plate as Will be readily understood in order to further hold the said slide 27 in i s P PQL operative position. a second bracket- ?(3 is provided therefor at the side opposite the bracket 75. llie trip it its inner end engaged over a rod 77 extending between the dogs '70 and passing; through the same and having its ends pivoted in lugs 78 on the under side of the slide 15 at the edges of the same. il hen the stop '73 is thrown out of engagement with the plate 66 the trip '74 will project slightly av H "from the connecting rod 77 and the dogs so that the said dogs will be held in such position as to engage the post-(12nd. When the free end of the trip is brought agaii'ist 5 the bracket or stop 7 through the action of the slice 2! said free end will be swung toward the dogs and the other end will exert a sliglit p ill. upon the rod (39 so that the dogs will be vibrated and the teeth 71 of the same released from the post-card hich may then drop into position against 1e negative it is thought the operation and advantages oit iny improved printing apparatus will. le readily understood. A supply of postcards 's placed Within the hopper l3 and the negative from which prints are to be made supported Within the negative compartm nt provided by the sills or beams surrounding the openings it and 5 in the face plate and the back plate, and a post-card is placed against the negative to start the operation. it is then necessary only to aise and lower the handle or operating lever 28 until the supply of post-cards has been ex hausted in order to make the desired illustrations upon the cards. Vl hen the lever is brought down so as to hold the post-card against the negative, the shutter Will be opened as hereinbetore described, and will be held opened to admit light through the negative to the card as long as the lever is depressed. Upon the lifting of the, lever, the shutter automatically closes and cuts off the light While a second sensi ized post card is being ted into position behind the negative. hen the lever is raised the finger 39 Will actuate the lever 45, as before described, and the slide 27 Will. thereupon be moved toward the right of Fig. 2, as before stated. This movement of the slide 2? will actuate the lever to discharge the printed postcard, and Will turn the dog 24 out of the path of the rib t? and consequently permit the spring 21 to draw the presser arm 20 down upon the nut or ring 18 so as to exert the required pressure upon, the post-cards within the hopper. These movements will occur before the card feeding slide 15 is actuated, owing to the factthatthe slot 6% in the slide 27 will ride past the pin 65 until the outer end of the slot engages the said pin. hen the end of the slot (3% has been brought into engagement with the pin (55, the slide 15 will be actuated so as to detach the lowest post-card and carry the same from the hopper into position to drop upon the negative. The impulse given to the pin (35 by the end of the slot- 64 will swing the free end of the trip M slightly forward of the rods (19 and 77 and the dogs will thereby be caused to engage the bottom of the post-card so as to positively carry the same from the hopper. lVhen the slide has about completed its movement said free end will strike against the stop or bracket '75 and the trip will thereby be swung rearwardly so as to act on the rod 77 and thereby vibrate the dogs so as to release the teeth of the same from the post-cards and hold them below the cards so that they will not act on the cards while the slide is returning to its initial position. Should it be desired to use photographic paper which is lighter than post-cards, the movable stop 73 will be turned into such position as to engage the plate 66 and hold the same against iovenient independently of the slide. and ae dogs will then be held constantly inoperative.

The device is intended primarily for use in printing post-cards, as stated, but it may be readily adapted for printing other forms of photographs, and the blocks or plates i may be adjusted so as to accommodate printing paper of various sizes. The arrangement shown and described for maintaining pressure upon the post-card within the hopper not only furnishes a ready means for maintaining the pressure notwithstanding the diminution in the supply of cards, but also permits the follower to be easily removed from the hopper in order to permit a supply of post-cards to be placed therein. Ir sheet of ruby paper may be placed over the shutter and the shutter provided with a central opening in order to prevent the light acting on the post-card while the same is being properly centered upon the negative. The lever or operating handle may be held depressed for a longer or shorter period of time in order that the printing may be properly ineasuret according to the light in which the work is being done.

in Fig. 9 I have shown an amplification of the feeding mechanism in which an upper deflecting plate 79 is arranged between the upper ends of the blocks S. The card will pass under this deflecting plate 79 and will be positively guided to the negative and prevented from falling away from face plate. A strip of felt 80 is secured to the lower end of this deflecting plate and extends therefrom over the negative to serve as a cushion between the negative and the presser plate 29.

In Fig. 10 I have shown a modified arrangement of the devices for applying pressure to the cards within the hopper. In this form of the device, the spring 21 is not employed but a spring 81 is provided at each side of the hopper, the said springs being secured at their lower ends to the guides 14 and at their upper ends to a cross bar 82 arranged above the hopper and having a cent 'al opening through which the stem 17 projects. The end of the lever 20 is, in this instance, swiveled upon the nut 18 and bears against the underside of the cross bar 82.
