The bolt 8 and catch can be provided at each edge oi the base if desired.
Mounted upon the base 1 is an opaque casing or box 9 providing a dark chamber, and composed of telescoping outer and inner sections 10 and 11, respectively. The outer section 10 is secured upon the section 2 of the base, While the section 11 is slidable upon the base, and is provided at that eui thereof remote from the section 10 with lens 12 pro vided with a suitablesluitter (not shown) in mannei of an ordinary camera.

A thumb screw 21 is carried by the slide 19 for holding it 1n various adusted positions.
In using the device for producing photographic prints, the opaque negative'is applied to that side of the holder 18 confronting the lens 12, and is held in place by means of pins, tacks, clips, or the like. The sensitized paper is introduced at the rear end of the casing 9 in front of the back 13, by means of the holder 15 which carries the paper, said holder having a removable slide or shutter 27 normally excluding the light from the sensitized paper and which can be withdrawn after the holder 15 is applied, thereby enabling the sensitized paper to be exposed Within the dark chamber. The device is so placed that the negative is subj ected to the proper light, whereby the shutter of lens 12 in being opened will result in the printing of the picture, or the like, upon the sensitized paper, which after being properly exposed can be removed and developed. The sensitized paper holder 15 is used in the manner of an ordinary plate holder for cameras, as will be readily understood to those versed in the art. The prints can be made quicklyby this photographic process, and do not come in touch with the negative. A number of prints can be'made from the same negative without handling the negative, which remains in place upon the holder 18. sensitized paper can be used for the production of the negatives, instead of using the sensitized plates or films, and this provides for a saving, both in'the cost of the sensitized material and the development of the negatives. The negatives can be applied to the holder 18 even before they .are dried, and are not apt to become soiledas are ordinary negatives when handled too frequently or subjected to-moisture. The paper negatives can be developed with greater ease, are not sticky as ordinary negatives, and require no chemical such as Wlll sta1n the hands. Furthermore, with the present negatives there is no running of the emulsion as with ordi nary negatives. The paper negatives are also lighter and thinner than ordinary negatives whereby a numberoi them can be more compactly carried, than with, the use of plate or film negatives. Contrast sensi tized paper can be used for the prints,.
thereby providing prints of high and artis tic quality. Halation is eliminated, which ordinarily resultsv from the reflection and retraction of light by glass plates. Furthermore, the negatives can be tilted with the present device, that is, they can be arranged in an oblique plane relative to the axis of the lens 12. Light conditions being the same, the exposure will be of about the same length aswhen films or glass plates With the present device, commercial recacoe.
are used, or a trifle longer, depending on the nature of the sensitized paper. Time is saved, however, in developing and printing the paper negative without drying. The present device provides an admirable one for beginners and amateurs, since the method of printing can be quickly learned and easily carried out. paper negatives, recording data can be written upon the back thereof, which will not interfere with the subsequent printing, and the negatives can be readily mailed without being apt to be broken or injured as are plate and film negatives. The present device provides for other advantages which will suggest themselves to those versed in the art.
When the prints are to be of the same size as the negative, the lens 12 is set at a position midway between the holder 15 and the negative holder 18, and by moving the lens 12 nearer the holder 15, the prints are re duced, whereas if the lens is moved nearer With the opaque the negative holder 18, the prints are enlarged. When the holder 15 is removed, the image will be thrown upon the panel or screen 13 whereby the operator can observe able features are not wanted.
As seen in Fig. 3, a mirror or reflector 22 inclined toward the lens 12 has its lower end seated between the holder 18 and slide 19 and the upper end of the reflector is supported by means of one or more cords or equivalent elements 23 engaged with eyes, pins or similar elements 24 applied to the upper edges of the reflector 22 and holder 18. The negative 25'can therefore be laid upon the base 1 below the mirror or refiector 22, the light rays being reflected between the lens 12 and negatives 25 by means of the reflector 22. This is particularly advantageous when the negative cannot be applied to the holder 18, and permits of a delicate negative being used which would be impossible with the ordinary printing process.
Having thus described the invention, what is claimed as new is:
A. photographic printing device comprising a Hat base; a casing resting directly on the base; a paper-holder in the rear end of the casing; a lens in the forward end of the casing; a slide mounted to reciprocate on the base in front of the lens; a standard fixed to the slide and defining an angle therewith; a' reflector inclined toward the ire lens and having its lower edge seated in said In testimony that I claim the foregoing angle; and an adjustable connection be as my own, I have hereto aifixed my slgnatween the upper edge of the reflector and ture 1n the/ presence of two Witnesses.
