1 Claim.

This is a divisional application, as originally filed July 18, 1938, Serial Number 219,786.

Our invention relates to the photographic exposing and developing machine and more par ticularly to the apparatus which is used and adapted for exposing the photographic image upon the passing paper for simultaneously developing and rewinding it in readiness for use.

I Another object of our invention is to provide a suitable picture photographing means for photographing pictures upon said emulsion coated paper, comprising a suitable means for feeding said paper from a roll which is fed through a paper carrier, said paper carrier being adapted to receive a picture film having a suitable projection means and a suitable light ray concentrating member for concentrating said light rays upon said film under which said paper is travelling or passing, also, having a suitable aperture so arranged whereby the linear speed of said paper when passing under the aperture provided with the film therein, may be moved and synchronized in the same direction and, at the same time controlling their linear speed, while the picture image from said film is transposed upon the surface of said passing paper.

Another object of our invention is to provide said picture photographing apparatus with suitable means for developing and fixing the picture upon the paper and for controlling its speed thereto and into another process of development, also having suitable means connected thereto for drying said paper over a suitable heated drum member, then allowing it to pass into a suitable duct through which a volume of drying air is allowed to pass. Said volume of air being agitated by a suitable agitating member attached and operated by a motor and adapted for drying said paper immediately after its development and in addition thereto having a suitable means for re-winding said developed and dry paper into rolls, having it in readiness for other and further process of operation.

Further objects and advantages of our invention as will hereinafter more fully appear, we attain by the construction herein shown on the drawing and described in the specification, forming a part of our application.

Reference is had to the accompanying drawing, in which the similar reference characters denote the similar parts.

In the drawing:

Fig. 1 shows the diagrammatical and elevational view of the picture applicating apparatus, adapted for applying the picture image upon the surface of the passing paper, for fixing and developing of said picture, then drying said paper and finally re-winding same upon a. suitable roll.

Fig. 2 shows a perspective diagrammatic'al view of the picture film carrying apparatus showing the aper passing thereunder and having means for actuating said apparatus at the same linear speed and operating in conjunction with the passing paper.

Describing our invention more in detail, said invention comprises the photographic apparatus for photographically reproducing pictures and wherein the sensitized paper in a continuous form is used for transposing pictures and upon its surface in succession or at intervals and which may be for the purpose to photograph and reproduce work of art or advertising matter, which may be used in out form, such as pages for periodicals, or, for any other advertising matter as may come within the general course of business.

Said apparatus comprises a frame I32 which is provided with a suitable hanger I34 upon which a roll of sensitized paper I04 is rotatably posi-. tioned and wherefrom the paper web I06 passes under a roller I36 then into a suitable holder I38 having an aperture wherein the picture film I39 is positioned as shown, the construction of which and its operation will be presently described.

The pictures or image from the picture film I39 and upon said paper surface are transposed by means of the use of suitable lantern member I40 having a passage I42 allowing the light rays to pass into a suitable light beam concentrating lens I44, which is provided with a suitable shutter member I46 and which is operated by means of a suitable solenoid member I48 as shown.

After the picture from the picture film I39 is transposed upon the paper surface, said paper I56 passes between a pair of feeding rollers I50 wherefrom it is guided by means of glass rollers I52 and I54 into and through a developing tank I56 wherein the pictures are developed, while said holder I38 together with said film I39 slides downwardly and is held at its lowermost position in readiness for another sucessive exposure.

From said developing tank I56, the paper is then guided over a roller I58, then under the roller I60 and again over a roller I62 thus passing into a and through wash tank I64, wherefrom it is led and guided by a means of guiding rollers I66 and I68 respectively into and through a fixing bath tank IIIl which will allow the photokinetic action in said emulsion upon said paper surface to be promptly fixed and the resulting picture registration to be permanently established.

When the paper passes through and from said fixing bath tank I78, it is necessary to allow said paper to pass over a roller I12 and into a wash tank Il wherein it is guided by means of rollers I16 and I78, then allowing it to pass between a pair of wringer rollers I88 in order to extract and eliminate as'much as possible the moisture from said paper, whereupon the paper web I96 is permitted to pass over a suitable drum I82 which may, if so desired, be heated by suitable heating means (not shown) for the purpose to permit complete evaporation of the moisture therefrom.

Said drying drum I82 is rotatably mounted upon suitable bearing or trunnion I8 5 which may, if so desired, be mounted upon or connected to the upright extension of the frame I32, so as to shorten the operation and drying process which in rotation said drum I82 allows the paper I06 to pass over a plurality of airing rolls I86, I88 and "ISO passing into a guiding roller I92 which guides the paper into an air duct, I94 and then allowing it to'pass through a re-wind apparatus I915, wherein said paper web IE5 is wound into a roll I98, as shown.

It may be noted that the photographing apparatus, as herein shown, produces a certain amount of heat which is generated by a lamp 280 and therefore we have provided a suitable fan 202 at the upper structure of the enclosure 234 which is for the purpose toblow the hot air downwardly andjinto a sub-duct 266 leading into the duct I94 previously mentioned. Thepaper web I'tlfi'passing through the photographing and developing apparatus runs very slow through the entire process and therefore the chemicals used in the developing and fixing process may be quickly removed, exchanged, or added thereto without diminishing the speed of the machine and for that purpose, we have provided said apparatus with a water pipe line 268 which is provided with water inlets 2H), each being'provided with a suitable v-alve'member 2E2 as shown, and, for the purpose of draining said tanks, each of said tanks I 56, I64,

I78, and I14, is provided with a suitable drain pipe 2M, so that after each operation or after a certain period of time, all the chemicals may be drained therefrom and the tanks cleaned out with fresh water.

The drive for said machine, may be arranged in any manner most adaptable in practice, therefore, for the purpose of'driving rollers I58, I60, I62, also roller I12, and wringer rollers I33, then drying drum I82 and airing rollers I56, I88, I90 and I82 inclusive, also, the rewind apparatus I96 may be driven by suitable mechanism, which is simple in its operation and therefore its descriptionis not deemed necessary.

However, for operating the photographic apparatus and thepassing paper in synchronization, the lantern Edi} and the shutter mechanism I46 also thesliding movement the aperture holder ltgincluding said rollers I50, are combined together and are provide-d with a suitable drive, comprising a motor, 2I6 having a reduction gear 2 I8 operated by means of a belt 220, said reductiOngear'ZIB transmits its power by means ofa suitable chain 222, which is connecting a suitable sprocket mounted upon a cross shaft member 224, see 'Fig, 2,"which in combination are adapted to drive said feed rollers I 50 by means of a chain 226, and which is also utilized for actuating and l'Ql idingthe sliding movement for said aperture holder I38.

One end of said cross shaft member 224 is provided with a suitable timing plate member 228 which is provided with a plurality of timing pins 230 and which are so arranged, whereby the synchronization lever member 232 is actuated thereby, as shown more particularly in Fig. 2, said lever member 232 is fulcrumed as at 234 having an estension which extends rearwardly and to which the aperture holder movement controlling lever 236 is attached and which is adapted to control the movement of said aperture holder I38 in synchronism with the linear speed of the paper web I06 passing thereunder.

In operation, the source of energy is delivered from the generator 24!], see Figs. 1 and 2, respectively, or, it may come from an outside source in any form, as in practice may be most desirable and which may provide sufficient current for energizing the lamp 200 and for operating the fan member 282 including the motor, also for driving the power motor 2H; of the apparatus, wherein the electric circuit is controlled by a suitable main switch 242 proyided'therein, as shown.

Further, in order to operate the solenoid I48, which is opening and closing the shutter member I45 in synchronism with the vertical movement of the aperture holder member I38 while the paper web I98 moves: therewith and passes thereunder, the lever'23f2 is provided with a switch lever 2 6,4 fromfwhich a lead wire- 2 leads to said solenoid Hi8 and follo'wsthrough'the circuit leading into the main switch 242 while. the other lead wire 248 leads to the source. of energy 2&0 as shown, also, in order to prevent a possible slowness and for insuring thefaperture holder sliding movement in the frame 250 supported by the rodmember 235, and whenmoved by the lever member 232. which is, actuated by thetiming pins 28 B, asuitable tensionfsprings' 252 are provided therein, which are for the purpose to hold said aperture holder I38 in its lowermost position and to hold same at all times in. readiness to be moved,

vertically by the. lever member 2 32 actuated by the timing pins, 238 during the revolution of said plate member 228';

The apparatusherein. described is adapted for and may be used in. printing-and photographing the diversified advertising matter upon the paper, andbecause of the particular construction of the apparatus andthe operation thereof as an individual unit or in combination, it may be used for printingand reproducing pictures and the advertising matter in'g-reat quantities.
