CARL JOSEPH LISH, OF LOUISVILLE.- KENTUCKY PHOTGGRAPHIC-PRINTING FRAME.

To ZZZ whom it may concern: 7

#7 it known that l, CARL Josnrn LTsH, a citi/ien of the United States, residing at 1131 S. l2thSt, Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Photographic? inting Frames, of which the following is a specification.

i his ntion i'-.a:';e.s to pho A i, printing appa atus, and its ob iectis to provide such apparatus with means for punching the prints w .h p r holes to enable a batch of prints be nef simultaneously by placing the same on a ng table havupstanding pins on which the prints are mounted by means of the punched out holes.

The object stated is attained by means of a novel combination and arrangementof parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompan ng drawing forming a part of this specii .tion.

In the dr wing, Figure l is a plan view of the invention, and Figs. 2 and 3 are crosssections on the lines 2-2 and 3-3 of Fig. 1.

The preferred embodiment of the invention has been shown but it will be understood that various changes and inodifica tions may be made without de arture from r the spirit and scope of theinvention as claimed hereinafter.

Referring specifically to the drawing, 5

scribed, and it has a movable section 9 seatj ing in an opening 10 made in the lid, and carrying the glass 8. The walls of the opening 10 and the edges of the section 9 are rabbeted to prevent said section from dropping downthrough the opening. On top of the section 9 is secured a sheet metal plate 11 having a rectangular opening through which the glass 8 is exposed. This plate serves as a mask to outline the picture.

The plate 11 extends to one end of the section 9 and projects a short distance therefrom, and is here provided with a hinged Specification of Letters Patent. Patented Sept, 28 1920,

plate 12 the function of which will be presently described. An ordinary spring hinge connection 13 between the plate 11 and the plate 12 is provided. I

To the projecting end of the plate 11 carrying the hinged plate 12, on the under side of the former, is fastened, by screws or other suitable means 14:, a cross bar 15, projecting at its ends from the plate. The opening in the lid 6 in which the section 9 seats is continued to accommodate the projecting ends of he cross bar 15, and said ends carry depending guide pins 16 working in apertures 17 in a pair of superposed cross bars 18 and 19 respectively, bolted or otherwise secured, to the under side of the lid 6. are coiled around the pins 16 between the cross bars 15 and 18. t will be evident from the foregoing that the section 9 is yieldably supported in the opening in the lid 6, and it is normally held slightly elevated in said opening by the springs 20. The cross bars 18 and 19 a bolted together or otherwise rigidly connerted; or a cross bar may be used.

The cross bars 18 and 19 carry upstanding punch pins 21. positioned to enter apertures 22 in the cross bar i5, and registering apertures 28 in the plate 11, when the section 9 is forced downwardly in the opening 10. The'plate 1 has apertures 24- adapted to register with the apertures 22 and 23, and is also provided with apertures 25 to seat the heads of the screws 14, when the plate is swung down. Springs 26 are coiled around he pins 21 between the cross bars 15 and. 18, these openings having the same funiition as the springs 2-0 hereinbefore described.

In use, the negative and the print paper are placed on the glass 8, and so positioned that they lie at one end above the apertures 23. The platen 7 is now swung down to press the negative and the print paper in close contact with the glass. The under side of the platen is fitted with a felt or other pad as usual. When the platen 7 is pressed downit forces the plate 12 down on top of one end of the negative and the print paper, and upon continuing the-pressure, the section 9 is forced down in the opening 10, whereupon the pins 21 are exposed through the apertures 23, and the negative and the print paper are forced over the same to Springs .20

punched out holes.

negative and print may now be removed The print is thus formed with two holes near one of its edges. A number of prints so punched may be placed on a cutting table having a pair'of upstanding pins on which the prints are mounted by means of the The entire batch of prints may thus be trimmed simultaneously and uniformly.

I claim: r
