Application mea ombuc, 1921. serial No. 505,796.

To'all lwhom it may cncern:

Be it known that I, JAKo KALMANO- vIToH, acitizen of Russia, residing at Brooklyn, in the county of Kings and State. of

New York, have invented certain new and useful Improvements in Photo-Reproducing Apparatus, of whichl the `following is a specification.

The principal purpose of the present invention is to provide an apparatus for reproducing photographic copies of pictures in an easy and rapid manner, in any desired numr. A further object isin the provision of a cabinet containing means for feeding the sensitized paper in single sheets from a supply carried therein.

Another object is to provide means for exposing the sheets to the printing effect 'of light without manual contact and finally, to store thefsheets until required.

Theseand other like objects are attained by the novel construction and combination of parts hereinafter described and shown in `the accompanying drawings, forming an essential part of this disclosure, and in which l p Figure 1 is a partial Side elevational, partial sectional view of a photo-reproducing cabinet made in accordance with the invention.

Figure 2 is an-enlarged sectional view of the upper portion thereof.

Figure 3 is a detail view of one of the paper transferrers.

Figure 4 is a side view of the cabinet as assembled.

Figure 5 is an enlarged fragmentary sectional .View of the exposure chamber.

Figure 6 is a transverse sectional view taken on line 6 6 of Figure 2.

Figure 7 is a perspective View of one of the negative supports.'

Figure 8 is 'a similar view of the mating support.

The cabinet comprises a `base section chambered to receive drawers 10 and 11, above which are other drawers 12 and 13 having over them a horizontal partition 14,

and at the front, between the wall and the drawer 12, is a narrow drawer l5;

The front wall 16, above the partition 14, is slanted rearwardly and contains two doors, respectively 17 and 18,-the lower door 17 being connected by hinges 19 at the bot- The cover plate 21 of the cabinet is engaged by hinges 22 at one side, and the main door` 23 at the back has hinges 24 as shown.

Below the cover 21 is a clear space or chamber 25 in which is a movable block 26 mounted on wheels 27 adapted to travel on rails 28, the block being drawnforward, toward the door 18, due to van attached cord 29, passing over a pulley 30 revolubly mounted in the cabinet in front of the block, the cord eXte ding rearwardly over a pulley 31 and then llownward to a weight 32.

This weight hangs pendant in a space 33 between the walls of the drawer carrying chambers and the rear door 23, as best shown in Figure 1, and is adapted to pull the block 26 to the front.

Fixed to the end walls of the compartment 25 are slotted guides 34 having sharply Vbevelled, down turned edges 36 inclined at an angle corresponding with the face of the block 26.

A strip 37, having a bevelled upper edge extends across in angular register with the bar 35, these elements limiting the forward movement of the sheets or cards 38 pressed against them by the block 26.

Immediately in front of the strip 37 is an opening 39 leading to a chamber 40 normally closed by the door 17, rearward of which is a compartment 41 and further to the rear is another compartment 42 containing a drawer' 43. Y

A channelled strip 44 passes across the top of the compartment 40 and a similar but reversed strip 45 is at the bottom, adjacent another space 46 leading to the chamber 47 containing the drawer 15.

The channels of the strips 44 and 45 serve to receive a .negative 48` and suspended in front of Ithe negative, on a transverse rod 49 are a p'air of opposed frame like elements 50 and 51,l having engaging hooks 52 and 53.

A Extending from the frame element are arms 54 and 55 containingundercut Irecesses receptive of the arms 56 and 57H of the oppositely disposed element 51, thus allowing relative adjustment; the arms 56 and 57 are suited to engage the negative 48 and are pressed into position by-a block 58 removably engaging the inner surface of the door 17' by hook fastenings as shown.

An electric lamp 59, in the compartment 40 furnishes lightto print the sensitized cards, the lamp being provided with a switch (not shown) by which it is controlled.

The card is pressed against the negative, in addition tothe block 59, by a. bell-crank lever bar mount-ed to rotate on a rod 6l, the other arm 62 of the bell-crank being engaged with a hook 63 fixed to lower part of the door 17 and is normally pressed forward and the door held closed by a spring 6l, contacting with the arm 62 of the bellcrank and 'fastened rigidly at its lower end to the front wall of the chamber 47.

In order to dispense the cards singly in progressive order from the supply.a pair -of shafts 65 and 66 are journalled in the side `frames of the cabinet, these shafts being connected by gears 67 and 68 adjacent one of the cabinet walls and the shaft 65 is provided with an extending crank handle 69 by which they are rotated,` obviously in reverse directions.

Mounted midway in the length of these shafts are elongated collars 7() and 71 to which are secured pairs of projecting forked heads 72 and 73 carrying pliable contact elements 74 and 75, made of rubber or like material, these elements being pressed outwardly by springs '76 and 77, so as to cause contact with the faces of the cards.

Due to the timing of'the gears, the element 75 first engages the outermost card from the stack 38, the contact sufficing to raise the bottom of the card above the bevellcd edge of the strip 37, and passing along. permits it to spring back over the bevelled strip, whereupon the upper element 7 4 draws the corresponding edge of the card from below the strip 36 and, in addition to the gravity of the card, urges it to drop through the passage 39 into the compartment 40, where it is adjusted over the negative 48 and the print made. y

Eventually the cards, after printing, are received in the drawer 15 and the usual process of developing employed. l

Having thus described my invention and set forth the means of its construction, application and'use, what l claim as new an'd desire to secure by Letters Patent, is

1. A photographic reproducing apparatus comprising a plurally compartmented cabinet, one of the compartments containing a stock of sensitized cards resting at an oblique angle upon their edges. bars having bevelled edges extendingr transversely in front of the cards, means for raising the .lower edge of the icards to pass over the beveled edge of the lower bar, means cooperative therewith for frictionally actuating the card thereover, a slidable block for pressing the cards against the said bars, a weight controlled means for actuating said block, and mechanical means for releasing the outermost card and for dispensing the same form the compartment.

2. A photographic reproducing apparatus comprising a plurally compartmented cabinet. one of the compartments containing a stock of' sensitized cards, a pair of oppositely actuated rollers, means on said rollers for feeding the cards singly from the containing compartment, said means comprising pins fixed in the roller blocks slidable on said pins, wipers set in said blocks and springs encircling said pins adapted to press said blocks outwardly. an adjustable frame removably engaged in another compartment, said frame being adapted to contain a negative, a pressure elementfor assuring contact of' the card with the negative, a printing means in said cabinet` said pressure element being actuated by the door to said compartment in opening and closing the same, and a spring adapted to intercept the card and hold .it prior to the operation of said pressure means.

3. A photographic reproducing apparatus comprising a plurally compartmented cab inet, a block having an -inclined face movable in the uppermost of said conipartments, gravity-operated means for moving said block toward the front of the cabinet, fixed bars having outwardly bevelled edges against which the cards are forced at their upper and lower edges, a pair of shafts mounted in parallel in front of said bars, said shafts being geared together to operate in reverse directions, means for manually rotating said shafts, and pliable, and spring actuated wiper elements carried by each of said shafts in timed relation to engage and dispense said cards singlyv in progressive relation. p
