UNITED STATES PATENT OFFICE HENRY A. BEEDY, OF ST. PAUL, MINNESOTA rao'ro-rnmrriwe MACHINE Application filed June 22, 1929. Serial No. 373,011.

This invention relates to a photo-printing into light compartments 11 and 12. A secina chine adapted to print simultaneously nd partition 13 separates the compartments from a glass plate and from a relatively thin 11 and 12 from a space 14 within the front of film. the housing for a control switch 15. The

Thus the platen 95 'tially rectangular shape anda removable top 24 is movable to conform to the position 8- which is normally held in place by suitof the opening 21 in the support 22. A able hooks 9 at the front and back of the leaf spring fixed on the lever 27 is armachine. The interior of the housing 7 is ranged to distribute the pressure applied divided by a thin, sheet metal partition 10 by the lever to opposite sides of the coveriuo '25 above the platen 24. A rigid stud 85 projects from the lever 27 to engage the movable element of the switch 15. movable'switch element is slidable vertically in the space 14: within the housing and is urged upward by a coiled spring 37 engaging its lower end, a suitable guide socket 38 being provided. .As best shown in Figs. a and 5, the'switch element is formed from insulating material and has an electric conductor 39 extending throughit and project- =ing. at, opposite sides to simultaneously en gage spring contacts e0 when the movable switch element is depressed. The spring contacts constitute terminals of circuit wires 41 and 42. 7

'Within thecompartment 12 is a pair of lamps43 adapted to illuminate the plate 18, and there is also in this compartment a pilot lamp 4% of lesser candle power. The compartment 11 contains a pilot lamp and a relatively powerful lamp 16 for illu-- minating the film 19. As shown in .Fig. 6,

the severallamps i3, 14, 15 and 46 are dis-- posed in parallel cir cuitsbetween the circuit wires 41,42 and another line wire17 for supplying electrical power. It will be evident that the lamps 4-3 and 46, in the an rangement shown, are controllable by the switch 15. A rheosta-t as is placed in series with the lamps43 to control their jillumi- 40. projects through an opening in the housing ,7 where it may be manipulated to move the card stock.

nation, this rheosltat, asshown in Figs.1,2 and a, being convenientlyfmounted upon the back wall of the housing 7 v The lamp 4:6 is preferably made adjustable horizontally and parallel to the partition 10 so as to give the most advantageous distribution of light. To this end, the lamp socket .is made slidable in the compartment 11 au'da rod 19 is, secured to the socket and lamp. 1 I x In use, the film and plate for commercially printing'cards of a particularsize are mounted in a suitable support 22 having an opening 21 adapted to receive the sensitized The plate 18 and film 19 are secured edge to edge, as indicated in 1, within the opening 21 and are supported upon the flanges 20 in such amanner that the lower surface of the plate 18 is offset- .downward from the film, as indicated in Fig. 3. The support 22 is now placed between the guide strips 23 and moved later- 7 ally to bring the edge of the plate 18 against the upper edge of the partition 10, as shown v in Fig. 3. Thus the plate 18 islocated in proper relation to the light compartment 12 and the film 19 is held inproper position at the opposite side of the partition 10 so as to be illuminated by light from the compartment 11. The position of the platen 24s is now adjusted by means of the bolts 31 to register with the 1 opening 21. WVith the This lamps connected in a suitable electric circuit, as shown, a card or other sensitized sheet may be placed in the opening 21 and the exposure made-by merely operating the lever 27 forward and downward until the stud 35 closesthe switch 15, the lever being held in depressed position for the period requiredfor theexposure. As will'be read- .ily understood, closing the switch 15 closes the circuits for the lamps 4:3 and 46. The

operator merely releases the lever 27 to terminate the exposure- By adjusting the rheostat 48,1119 intensity of the light from the lamps 13 may be adjusted to meet the requirements of the. particular plate 18 employed in the printing. Obviously, when themachine'is once adjusted, a large-number of cards or sheets of stock may be exposed in rapid succession and the printing from the film. and plate is simultaneously.

accomplished by a single handling of; the" stock. v 1

It will now be understood that the partitron 10 extends upward through the printing surface to divide it .for the film and plate and that the printing surface for the film is offset upward from that for the plate by my arrangement ofthe relatively thick' glass closure-17 formingthe printing surface for the film.
