JOSEPH TRIMBAGH, OF RYE, NEW YORK.

PRINTING-CAMERA.

Application filed May 14, 1915.

To all whom it may concern:

Be it known that I, Josnrrr TRIMBACH, a citizen of the United States, and a resident of Rye, in the county of Vestchester and State of New York, have invented certain new and useful Improvements in Printing- Cameras, of which the following is a speci fication.

My invention relates to photography, particularly to means for printing positives from negatives, and is an improvement over the form shown and described in my application for Letters Patent of the United States filed Jan. 9, 1915, Serial No. 1369. In the form referred to the hood was slidably removable from the cabinet, as was also a drawer for the reception of a transparent panel which was adapted to bear upon the negative and the print paper thereunder, an eXteriorly operable shutter being required. In my present form, however, this sliding of the hood is eliminated, as are also the drawer and the shutter, although I may employ the shutter if desired, the hood being in permanent and hinged connection with the cabinet whereby it may be swung backwardly to allow the substitution of a new negative and, in the event of cut print paper being employed, of anew sheet thereof, thus simplifying the operation of printing. When a number of prints are to be made from one negative, I provide the roll of print paper disclosed in the application above identified, or I may make single positives from separate negatives from this roll of sensitized paper as well.

The device is primarily adapted for use in a dim light, as is usual with gas-light papers, but the device contains the printing light or lamp, as well as a non-actinic lamp which may be used to position the negative and positive sheets, after which the white light is turned on and the printing begins.

My invention is fully described in the following specification, of which the accompanying drawings form a part, in which like characters refer to like parts in each of the views, and in which Figure 1 is a perspective view of my invention, ready for use; Fig. 2 is a central vertical section therethrough on a line from front to rear, in operative arrangement of parts; Fig. 3 is an enlarged, fragmentary, sectional detail view; Fig. 1 is an enlarged view similar to Fig. 2, but with the hood Specification of Letters Patent.

Patented Nov. 30, 1915.

Serial No. 28,043.

thrown back out of operative position, as for the substitution of a new negative, new sensitized paper, or both; Fig. 5 is a horizontal, plan and section taken on a line above the cabinet, and partly broken away; and Fig. 6 is an enlar ed, fragmentary, section on the line 6-6 of Fig. 2.

In the drawings forming a part of this application I have shown one embodiment of my invention, comprising a cabinet 7 divided into two compartments 8 and 9 by means of a partition 10, the former of which is somewhat hi her than the latter so that cut-outs 11 result in the sides of the cabinet as shown in Figs. 1 and at; the compart ment 8 is open at its top and provided with a light-proof lid 12 to permit the insertion of a reel 13 carrying a roll of sensitized paper 14:, and the top of the compartment 9 being covered by a horizontal plate 15 serving as a support for the paper 1%, a fingerhole 16 being provided in the front thereof to allow grasping of said paper to draw it forwardly when desired.

Secured to each side of the cabinet, at the uppermost points thereof, is hinge 17, which hinges are also connected with the respective sides of a frame 18 filling the cutout portion of the cabinet, said frame consisting of the sides 19, front 20, back 21 which closes off the compartment 8 when the frame is in operative position but does not quite touch the plate 15, a slot 22 resulting to permit the passage of the paper 14 from the reel to the front of the cabinet; as shown in Fig. 6, the lower edge of the frame 18 is preferably provided with a felt strip 18 to render the interior of the device light-proof, and the sides of the frame are provided, interiorly thereof, with grooves 23 for the reception of a glass negative or, as shown, of a transparent sheet of glass 24: to hold the film negative 25 flat against the paper 14, this being made in any desired form.

Carried by the frame 18 is a rectangular bellows 26 surmounted by a rigid hood 2'? of truncated pyramidal form which is pro vided with a window covered by a ruby, orange, or other non-actinic glass 28, the top of the hood being closed by means of a plate 29 carrying two electric lamp sockets 30 and 31 for ruby and white lamps, respectively, provided each with a switch or having a switch adapted to throw one lamp in and the other out at will, this not being illustrated as any one of a number of well known forms may be employed.

The hood 27 is maintained in desired relationship with the frame 18 by means of vertical rods 32 carried at the corners of the latter and sleeves 33 carried at the corners of the former and slidably locked on the respective rods by means of set screws 34: or equivalents, the rods 32 being of suflicient length to permit full extension of the bellows 26 to move the lamps into desired relationship with the paper 14.

The film negative may be buckled and sprung into place when the hood section, including the frame 18 and the bellows, is thrown backwardly on its hinges and, when the hood section is returned to operative position, said negative bears upon the paper 14: which rests upon the plate 15., and printing may begin. If a glass negative is used, the glass plate 24 may be removed to permit the negative to replace the same, and I may, although not shown, provide asuitablecatch for holding the cabinet and frame together tightly during printing. \Vhen a print has been completed the free end of the paper 1% may be grasped and the exposed paper portion detached by tearing from the body thereof, to undergo development, fixing, and washing, and this printing may be repeated indefinitely with one or more'negatives within the capacity of the roll paper, a key 35 being provided for the reel 13.

It will thus be seen that a simple though practical printing camera results which is adapted to glass negatives, cut orroll films, as the roll film could be rolled upon the reel with the sensitized paper in a dark room preparatory to printing, and to either :cut sheets of sensitized paper or a continuous roll thereof.

The ruby'lamp may be used to position the paper and in removing the same, the white lamp being used only for the actual printing, the lamps may be adjusted toward or from the paper according to the density or character of the negative, or the brilliance of the lamp.

There are no separable parts to be mislaid or lost, and the device may be collapsed into compact form, as for storage, packing, or shipping; While I have shown certain .details offconstruction, it will be obvious that I am not limited thereto, but may make changes thereover, within the scope of the following claim, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is:

A printing camera embodying a cabinet comprising side walls, front wall, rear wall, vertical and horizontal plates forming compartments and a cover for one compartment, respectively, said side walls being cut out to form upwardly directed members, hinges carried by said members, a frame carried by said hinges and filling said cut outs, an extensible light chamber carried by said frame. and means for holding said chamber in adjusted position with respect to said cabinet and frame, said frame being adapted to receive a negative, and saidhorizontal plate serving as a support for the sensitized paper.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
