PHOTO'GRAPHIC-PRINTING DEVICE. 4

Specification of Letters Patent.

(Application filed July 11,1911. 1 Serial No. 637,906.

Patented Oct. 8,1912.

T 0 all whom it may concern:

Be it known that I, MAX F. LONG, a (:ltlZEIl of the United States, and a resident of Evanston, in the county of Uinta and State of Wyoming, have invented a new and Improved Photographic-Printing Device, of which the following is a full, clear, and exact description.

My invention is a photographic printing device so made as to be portable and readily packed for shipment.

It also comprises features of construction whereby light entering the same will not be transmitted directly to the negative from which the photographic print is to be made, butwill first fall upon a mirror carried on the interior of the casing of the printing device and be caused to pass, by reflection, therefrom to a suitable opening in which the negative is held in place. Suitable means in the shape of translucent plates nate the negative'with non-actinic rays, to

allow the user to see where to place the paper on the negative at the start. As soon as the paper is put in place, light is permitted to enter the printing device without causing itto pass through the trans-.

lucent plates, and the operation of printing then proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, in which the same characters of reference indicate the same parts in all the views. Q"

Figure 1 is a perspective View of the lower-part of a window frame, showing my improved photographic printing device in situ; Fign2 is a'transverse' vertical sectional viewon the line 22 of Fig. '3; Fig. 3 is a transversesection-on the line 33 of Fig. 2; and Fig. 4 is an enlarged front elevational view of one of the shutters which carries plates of translucent material to modify the light when necessary.

On the drawings, 1 indicates the lower part-of an ordinary window frame having a sill 2, on which I rest a board 3, whigh serves as a base for my portable printing device. This board 3 may be lengthened by means of an extension piece 4 attached to the board 3 by a block 5, to suit the width of the particular window used. The board translucent material 26. These 3 serves as a-base or support to which the body 6 of my improved printing device is attached, and has an opening 6 there- -through to permit the rays of light to enter the printingdevicefi when the same .is in use.

The printing device is made up of 'triangular ends 7 united by means of a slantingback 8 on which is supported a mirror t3, and having an extended top-9. The top is horizontal and has an opening 10 therethrough which is cut out around the edges as shown at 11, toreceive the negative 12, from which the prints are to be made.-

The numeral 13 represents a pivoted lid or cover to closethe opening 10 and hold the negative 12 in place, with the paper on which theprintis to be made securely clamped between the negative and the lid. This lid is pivotally connected at the middleot'its long edges to the ends of a U-shaped piece of wire 14 pivotally mounted in a block 15 fixed to thetop 9 of the casing; and 16 is a spring attached to one leg of the wire 14 to hold the lid 13 in open'pOsition, as shown in Fig. 1, when the negative is to be put in place. When the lid 13 is forced down it fits snugly in on top of the negative 12,, and the'spring 16 engages the wire 14 in such a way that it always tends to raise the lid. This lid must be fastened to keep it down, and it may beheld in position if desired by simply causing it to fit tightly within the upper edges of the opening 10. n J a On the top of the cover 9, arranged adjacent the inner edge of the opening 10, is placed a bearing block 17, in which is mount ed a piece of bent wire 18. This piece of wire has one end shaped to form a crank, as

shownin Fig. 1, and itsother end has a hook 19, to which is connected a link 20 having a hook which engages the opening in the upper end of a bar 21. This bar 21 is per forated at intervals along its length to receive the crank-shaped ends of longitudinal operating bars 22, having journals, as shown at 24, which are mounted in apertures or hearings in the-sides 7. To each of these bars is fastened a shutter 25, each of these shutters being stamped from a single blank of metzil aving central openings cut therein which are filled by means of oblong pieces of orange-colored celluloid or other suit-able oblong pieces of translucent material are simply held in placeby bending over the edges of the shutter upon the edges of the piece 26 tightly enough to hold the latter in place. The bent-over portions 25 along the shorter "edges of these shutters are perforated to reor casing, illuminating the negative and enablmgthe user tov see how to put the paper on the glass or plate Without risk of the photographic paper being affected by the exposure. When the paper is on the negative the lid 13 is forced down by hand, and as soon as itis secured in place, so as toclose the opening 10, the wire 18 will be pressed down by the fingers of the hand, to-

lift the hooked end 19 and raise the bar 21. This will rotate the crank-shaped ends of the bars 22, to open the shutters 25. The printing device having been previously located at the bottom of the window frame, as shown on Fig. 1, light from Without will now pass freely through the opening 6 to the mirror 8 supported by the back of the casing 8, and thence by reflection through the negative to the paper.

.I wish to reserve to myself the right to make such small changes in the shape, size and arrangement of the parts as fairly fall within thescope of my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A photographic printing device comprising a casing, means to which said casing is secured forattaching the same to a win- ..dow frame, said casing having an opening in its front to permit the entrance of light to the inside of the same, a translucent member for controlling said opening, means for movably'mounting said member adjacent said opening and a mirror supported inside of said casing at an angle to said opening, said casing having an opening in its top and having means adjacent the top opening for supporting a negative in said opening in the top, whereby light passing into said casing through the opening in the front will fall upon said mirror and pass therefrom to said negative by reflection.
