DEVICE FOR PRINTING- PHOTOGRAPHS.
To all whom it may concern:
Be it known that I, FREpERioK H. HAM- MER, a citizen of the United States, and a resident of Highland Park, in the county of WayneYand State of Michigan, have invented anew and Improved Device for Printing Photographs, of which the follow ing is a specification. s
This invention relates to means for print ing pictures from negatives by the photographic'process, and specially to that type of printing devices whereby the picture may be printed many times larger if desired,
than the negative from which it is pro duced; and its object is to provide a simple and effective printing mechanism of thistype which can be quickly and easily adjusted and which can be manufactured at com paratively low-cost. I This invention consists in combination with an adjustable support for the printing paper, of a case and collapsible supports thereforfof telescoping connections between the case and paper support, of a pair-of glass plateswithin the case so positioned that the grooves will be at substantially right angles to each other, an electric lamp within the case, and a proper reflector on the opposite side of the lamp from the grooved plates. I
It further consists in combination with'the construction above set fortli, of adjustable jaws for holdin cameras of any desired type which may e emplo ed with this projecting device, between t e grooved plates andthe paper support.
In the accompanying drawings Figure 1 is a detail of. the two grooved lass screens which are employed to diffuse "t e light employed for printing. Fig.2 isa perspective: of my entire construction, including a camera mounted thereon. Fig. 3 is a perspective of the front end of the device showing the jaws for holding the camera in position. Fig. '4 is a central vertical section of thig improved projecting mechanism. "Similar reference characters refer to like I parts throughout the several views.
The invention embodied in the accompanying drawings consists of acase -1, prefer-- ably of sheet metal and rectangular,having a top 2 and a, front end 3. This case may be provided with sockets 4 adapted to' receive the upper ends of the legs 5, which are pivotally secured to the inner sides of the side-bars 6 of a slidable frame having ends to the base 14. The
(T and a cross-bar 8. This frame telescopes m a second frame which may have side-bars 9 and One end bar 10, a brace 11 being preferably secured to the outer ends of the bars 9 and serving to position them with reference to the innner slidable-frame. The bars 9 are slidable in the guides 13 secured to the base 14, to which base may be hinged a toe-piece 15 which "connects to the board I 16. A pivoted link or brace 17 may be employed tohold this board 16. at right angles which the. light is to be thrown may be secured, to'the board 16 by any desired means, th umb tacks preferred.
The case 1 is provided at its rear end with an openin to receive the fixture 18 of an sisting of any desired number of flat plates 24, secured together by means 'of a shell 25, preferably of metal, may be mounted on the socket 19, and/ so constructed that the rays of light will be thrown forward. The result "is that a very much' .difi'used light reaches the grooved glass lates 26 and 27, which are supported wit in the case by means of theupright guides 28 and 29 secured to the sides of the case. One of these glass screens is grooved horizontally and the printing paper up on Specification of Letters latent. Patented Aug. 4, v1914, j Application'filed August 25, l ne Serial No. 788,355. N
electric-lig t socket 19 into which an elec- I tric lamp 20 may be screwed. Wires 21 and other vertically, as shown in Figs. 1 and 4,
and the ridges formed by these grooves serve to diffuse t eligrht, so that the rays of light WhlCll proceed om the plate 27 are of uniform intensity over the entire plate. In or;
der to further insure uniforr'nity a small bracket or guide 30 may be secured to the front 3 of the case around the opening therein,
It will be apparent that when the lens of the camera is in propenposition so as to approximately focus the negative which has been introduced through the slot 37, and which is held in position by the guides 38, and the current has been turned onto the lamp 20, that proper rays of light will passfrom the lens of the camera toward the board 16, that a picture will be projected onto the board, the size of which will depend upon the. different proportions and distances of the parts.
When it is desired to store or to ship this device, the camera, is removed from the case 1, the case is lifted from the supports 5 which are then folded down flat between the side pieces 6, the inner frame and outer frame are telescoped in the guides 13 of the base 14:, and the brace 17 is slipped off from one of the pins on either the back 16 or the base 14, permitting this back to fold down onto the slidable portions of the frame.
The sizes and proportions of the different parts illustrated in these .drawings may all be modified by those skilled in the art without departing from the spirit of my invention as set forth in the claims.
I claim.
1. In a projecting device for printing pictures from negatives,'the combination of a case, means to adjustably support the same with reference to a printing paper support, a lamp within said case, a reflector mounted within the case around the lamp, a pair of grooved plates of glass mounted adjacent the end of the plate which is toward the paper support, said plates being positioned so that the grooves of one plate are at an angle to the grooves of the other plate and the grooved sides of the two plates are adjacent each other, said case having anopening in the end adjacent said plates,*a pair of adjustable clamps mounted adjacent said openings, and a projecting lens mounted between said opening and said paper. support.
2. In a projecting device for printing pictures from negatives, the combination of a paper-support and acase, means to support them, said case having an opening in the side toward the support, an electric lamp within the case, a concave reflector mounted at the rear of said lamp, apair of grooved glass plates mounted between the opening in said case and said lamp to break up the rays of light passing from said lamp and reflector through said opening, a ground glass plate across said opening, a lens and lens holder mounted between the case and the papersupport, and means to secure the lens support to the case.
3. In a projecting device for printing pictures from negatives, the combination of a paper-support and a case, adjustable means to position the same relative to each other,
a camera mounted on the case and extendin 0 toward the paper-support, said camera and case communicating, a source of light within the case, and a pair of grooved glass plates between the source of light and the camera.
4c. In a projecting device for'printing pictures from negatives, the combination of a lamp, a lens, a support for the lens and the lamp and for a negative between them, and apair of grooved glass plates mounted between the negative and lamp.
5. In a projecting device for printing pictures from negatives, the combination of a lamp, a lens, a support for the lens and the lamp and for a negative between them, a pair of grooved glass plates mounted between the negative and lamp, and a concave reflector mounted on the opposite side of the lamp from said plates.
"6. In a projecting device for printing pictures from negatives, the combination of a case having an opening at its front end, a
lamp centrally mounted in said case, a reflector at the rear of the lamp to reflect the light through the opening, a pair of grooved plates mounted in the case between the lamp and the opening, apair of clamps mounted adjacent said opening, a pair of screws to position the clamps, and an open-back camera secured between said clamps.
7. In a projecting device for printing pictures from negatives, the combination of a base, a paper-support pivoted thereto, guides mounted 011 the base, telescoping frames mounted in said guides, foldable legs mounted on one of the frames, a case mounted on the legs, a lamp within the case, a support for negatives within the case, and
a lens mounted onthe case between the negativeand the paper-support.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses. J
