UNITED STATES CHARLES KANARIAN, OF NEW YORK. N. Y.

PHOTOPRINTING MACHINE.

Application filed April 8,

The object of my improvement is to provide a simplified construction, operatively manipulated either by power drivenmechanism'or by hand, as preferred, so as to facilitate as much as possible the work to be performed, as well as to combine and limit in one coi'istruction the elements of light and time exposure, so essential to the photo-printing art, thereby securing greater uniformity of results and a better grade of article produced for the market in increased quantities under similar conditions of time and labor.

The novel and useful features of the improvement will more readily appear from the forthcoming detailed description to be read in conjunction with the drawings and the claims.

Figure 1 is a perspective front and side view of the machine; Fig. 2 is a side view; Fig. 3 is a front View; Fig. 1 is a perspective of the printing frame with parts removed; Fig. 5 is a perspective of the cam operating paper dropper; Fig. 6 is a detail. of Figure 4; Fig. 7 is a cross-section of Fig. 2; Fig. 8 is a perspective of the printing frames C and 0; Fig. 9 shows the ratchet and pawl and Fig. 10, a plan view of multiple machines in a single frame.

The upright frame A and the auxiliary frame A support the motor driving elements E and the driven elements F by means of brackets 1, 2, and 3, Figure 1, which may be constructed out of any substantial material in the manner shown for convenience of individual needs or as necessity may require.

The light box B is fitted into the frame A, Figures 1 and 7 and is completely enclosed, having an adjustable body 1), adapted to carry the electric bulbs 15 and'to be moved forward or rearward relative to frame G by means of crank 16 rigidly secured to the threaded rod 17 which engages threads in plate 18 attached to body I), so as to regulate the i11'ten-; sity of the light desired to penetrate the translucent glass 19, clamped firmly in the frame C with the photographic plate that is to be reproduced by the co-action of the sensitized paper or print compressed by platen D in contact therewith and artificial light emanating from the light box B.

The'opcn rectangular frame C, Figs. 4.- and 8, is grooved along the inner margin to receive the translucent glass 19, and the photographic plate or film, as the case may be, which are clamped together by the threesided frame 0, adjustable therewith, by means 1925. Serial No. 21,589.

of the thumb screws 13 and the coil springs 14., the bottom section of 0 being absent so as to admit of the vibratory action thereunder of the paper dropper 11, Fig. and aid in the rapid removal of-the sensitized paper or print, after exposure, into the receptacle beneath, when the paper dropper 11, secured to the guide-rods l0, l0 and held in contact with the cams 7, 7, Fig. 5, is oppositely disposed or extended by spiral expansion springs 10 The sectional. threesided frame 0 Fig-. 53 is a most important feature of the clamping mechanism mentioned, as so constructed, for the reason that there no bottom section to obstruct, or interfere with, the paper or print on being released, as stated, in dropping instantaneously and automatically into the receptacle below.

The h in god-platen D is adapted to lit inside of the frame 0 to admit of the necessary compression on the paper print in contact with the photographic plate or lihn, secured in position on stanchion G by the leaf springs 12, Figs. 2, and 7, so to operate, and is faced or surfaced by any soft flexible substance, such as felt or crude sheet rubber, designated (Z, to give the requiste resiliency against too firm or over-coi'npression on the photographic plate and the translucent glass 19 and consequent shattering of the glass and the-destruction of the photographic plate or film.

stanchion G, Figs. 1, Qand 3, is so constructed as to carry platen D on the upper or outer end to whic'h'it is secured by the leafsprings 12, Fig. 2, and by the lower or inner end to control the electric contact switch 20 and is so fulcrumcd as to operate reciprocally by cam 8 through each cycle platen D over against thepaper-print, photographic plate or film and the glass 19, all clamped together in the frame C, which is interposed thcrebetween and the light box B, Fig. 7, and the op positely disposed contact switch 20 to light simultaneously therewith the electric bulbs in the light box B in order to throw artificial light on the photographic plate or film at the instant of contact of platen D with the sensitized paper or' print, that is compressed thereby, as stated, against the photographic plate or lilm in the frame C.

' The glass 19 is rendered translucent for the purpose of dili'using light emitted from the bulbs 15, and is fitted into the grooved inner margin of the supporting frame C, Figs. 4 and 8, together with the film or photographic plate and allare clamped thereto by means of the thumb-screws 13 in frame cunder tension of spiral springs 14 to prevent crushing or over-pressure. Frame G is then positioned at the head of thelight boxB. V

The power element may be of ageneral character of a single motor, as E, Fig. 1, of the ordinary type of dynamo construction,

having sufficient power to drive the worm 5,

bulbs 15 on thesensitized paper, the intensity of the light being regulated by the forward and rearward adjustment of body Z by crank 16 in the light box B. The leaf-springs l2, interposed between stanchion G and platen D 7 further serve to relieve too firm compression or overpressure from platen D with its soft flexible surface or facmg, designated (Z, on

the sensitized paper in contactwith the film,

photographic plate or glass 19, in frame (1. The combinational elements of my improved photo-printing machine as assembler and in operation nay now be briefly set forth. Each cycle or rotation presents successive steps or stages of operation quite analogous tothe paper printing art generally.

The photographic plate or film is clamped by the supplemental frame in frame C, Fig. 8 as described, which is firmly secured in the head ofthe light box B. The motor driving element, as motor E, regulates the speed during each arc of the rotation of the camshaft F according to the work to be, performed or being. performed, the length of time expo-.

sure of the artificial light from bulbs 15, and

the pause or dwellflof the reciprocating stanchion G in open position, to enable the operator to place the sensitized paper to be printed properly in position over the filmor plate and'agai'nst the paper dropper 11, Fig. 5,and the supplemental frame 0, which serve:

as a" register or guide in properly manipulating the paper-print to insure'accuracy in position and uniformity of the printed product.

The two cams 7, Fig. 5, through each revolution of thecam-shaft F acting on the camdriven members 9 move to'and fro the paper dropper 11. rigidly secured to guide rods 10 V or film, thus holding the paper print in position, in advance of the axial rotation of the fulcrumed stanchion G by a like or similar under the frame C, the glass 19 andthe plate action of cam 8, to which is attached at the upper end by the leaf-springslQ the hinged platen 1), adapted to contact by such co-action the sensitized print over the plate or film at the same instant that the electric contact switch'20 on the opposite end connects the current of electricity to light the bulbs in the light box B,'whence emanates the artificial light t. iroughglass 19 to reproduce the photograph or, imprint the film on the sensitized paper or print'in the usual manner adopted in the photographic art. Onthe completion of the revolution or cycle of the cam-shaft F the paper dropper 11 is released by the cams 7 and extended by the springs 10, presenting an opening or space under the frame 0 andthe platen I), through which the. paper falls. Consecutively stanchion G is released, disconnecting the contact switch 20 and carrying with it the hinged-platen D to return to open position. Another sheet of print or sensitized paper is inserted and the mechanicalsteps or stages of the cycle or revolutionare renewed. If desired, aratchet and pawl may be operably, connected to the worm-gear 6 and the cam-shaft F, as in Fig.

9, or any other suitable device, to enable the operator to stop or disconnect the power driving element at any desired position or to prevent accidents, as the case may be.
