Specification of Letters Patent. Application filed December 15, 1908. Serial No. 467,711.

Patented Aug. 3, 1909.

Be it known that I, CALVIN J. ELLIS, a citizen of the .United States, and a resident of Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Photoplanographs, of Whichthe following is a specification.

My invention relates to machines for vexposing, developing and fixing photographic films or other fabric chemically sensitized to the action of light, and more particularly to photo-planographs or machines for use in producing for commercial purposes direct photographic copies of drawings, legal'documents and the like.

It is the object of my invention to produce a'machine of this class of simple, durable and inexpensive construction, in which a supply ofthe sensitized material is carried in the machine in the form of a roll, manually op eratable mechanism being provided by which sections of the sensitized material may be intermittently moved into position for exposure,flthence passed into a developing bath, thence to a fixing bath, thedevel:

opedsection severed from the strip or band leading to the roll, and the severed prints then manually removed from the fixing bath for final washing and drying.

My invention is embodied in the various mechanical devices and combinations of .means by which the sensitized material is to my invention, Figure 1 is a side elevation of the machine, Fig. 2 is a transverse section thereof on the plane of the'line a:-:r of Fig. 1, Fig. 3 is a front elevation, partly in section, and Fig, 4 is a sectional plan view, the section being on the plane of the line yy of Fig. 3.

In the construction shown I providea camera consisting of a casing 1, provided at its rearward side with a bellows 2 connecting with a lens-board 3 carrying a lens 4, the lens-board being slidably mounted on a foldable bed-plate 5' and adjustable longitudinally thereof by means of a rack and pinion device, in the ordinary manner.; The bedplate may be provided on the side with a scale or series of graduations 6 for use in adjusting the lens to predetermined positions with relation to the casing 1.

form of a roll.

' means of a crank 13, by which the bar-may Above the casing 1 'andin hinged connection therewith is a casing 7 adapted to contain a supply of sensitized material in the Below the casing 1 is arranged a casing8 for containing the developing and fixing bath mechanism, and said casing 8 is mounted on a table 9 by which the body of the machine is raised to a convenient height above the floor. In the lower part of said table are arranged guides in which is slidably held a bar 10 which extendsrear- Wardly from the table, below the camera bellows, and is connected with the frame 11. The legs of said frame 11 are provided. with rollers, as indicated, and on the upper part of I the frame the obj ect-board 12 is hinged thereto in such a manner that the same stands. normally in a vertical position in front of the camera lens but may be tilted to a horizontal osition, as indicated by the dotted lines in ig. 1, for convenience in securing thereon the objects to be photographed or copied. The bar 10, adjoining the table 9 is provided with a rack and pinion device, actuated by he moved longitudinally to vary the position of the object-board relative to the camera. A scale or series of graduations 14 maybe placed on the side of the bar 10 for convenience in setting the same to predetermined positions. By the joint use of said graduations and the graduations 6 on the bed-plate 5, the camera may be adjusted to make pre determined degrees of enlargement or reduction without the necessity of directly-focusing the same for each object copied. To sup- 1 portend steady the rearward end of the bedplate 5, a leaf 15 is hinged thereto m such a manner that it may be turned down and rest upon the bar 10, as shown. Within the casing 7 a spool 16 is revolubly supported by means of a small shaft 17, the

front end of which extends through the casing. and is covered by a pivoted late 18 \VlilCh may be pushed aside and t e shaft withdrawn from the casing to release the spool. An elastic band 19 is attached to a hookat one .side of the casing and passed over the. roll X of sensitized material on the spool, the other end of the band being connected with one of a number of hooks 20 disposed at the; other side of the casing. serves as a brake to prevent too free a move-. ment' of the s 001, and the braking tensionmay be varie by engaging the band with- Said elastic band the camera casing 1 at one side thereof, ad-' joining the door 22 therein. A mirror 23 is disposed in a diagonal position in the camera casing, as shown in Fig. 4 to deflect the light rays from the lens so that the focal plane thereof coincides with the strip Y of sensitized material. The mirror also serves to reverse the image rojected by the lens, so that the same will e produced on the print in a positive or normal position instead of the negative or reversed position in which it is projected by the lens.

At the bottom of the camera casing 1 the strip of sensitized material passes between a pair of feed-rollers 24, which are preferably covered with resilient material such as rubber, so as to firmly grip the sheet. On the front end of one of said feed-rollers is a pinion 25 which meshes with a gear 26 provided with a crank 27 by which the same may be turned. The relative sizes of the gear and pinion are preferably made such that for' each revolution of the crank 27 the feed-rollers will be turned sufficiently to move the strip of sensitized material downward the width of the exposed portion thereof Immediately below the feed-rollers is arranged a cut-off device comprising a metallic bar 28 having a longitudinal slot or kerf in the edge thereof, and a knife-blade 29 adapted to enter said slot or kerf. The knifeblade 29 is carried by a bar 30 which is slidably held in suitable guides 31 arranged at the front and rear sides of the casing, as shown. The bar 30 is connected with small cranks 32 carried by a shaft 33 arranged in the casing behind the mirror 23, as shown in Figs. 2 and 4. On the front end of said shaft 33 is a small crank or handle 34 by which the shaft may be rockedto cause a reciprocating motion of the knife-blade, so that the same may be thereby forced into and withdrawn from the kerf in the bar 28, to cut off the exposed sections of sensitized material. I

In the casing 8- is a shelf 35 which is slidably supported on guides 36 arranged at the .66 frontv and rearsides of the casing near the bottom thereof. In the bottom of said slidable shelf are set racks which are engaged by inions 37 carried on a shaft 38, said shaft eing journaled in the casing and the front end thereof carrying a crank or handle 39 by which the shaft may be rotated. By means teams? of said crankshaft, pinions' and racks the shelf 35j may be moved longitudinally of the casing for a distance slightly less thanthe length of the shelf.

On the slidable shelf 35 is disposed a pan 40 in which are formed compartments 41 and 42 for containing the fixing and developing 'fluids, respectively. The compartment 41 issimply an open pan or tray of a size sufii cient to permit the sections of sensitized material to lie flat therein. The compart ment 42 is a relatively deep, narrow pocket, the opening to which adjoins one end of the fixing-fluid compartment, extending down wardly from said opening and, in the construction shown, curving around undershoulder which engages a stop 49 disposed on the upper side of the slidable shelf. The arrangement of the parts is such that when the slidable shelf is at one extreme of its movement as shown in Fig. 2, the opening to the developing fluid compartment 42 is immediately belowthe feed-rollers 24.

In the operation of the machine, after the section of sensitized material has been exposed in the camera casing, the pan 40 being in the position shown in Fig. 2, the feed- ,27 and the exposed section is thereby pushed down edgewise into the developing fluid contained in the compartment 42. cient time has elapsed to complete the developing action of the fluid, the slidable shelf 35 which carries the pan is moved toward the other end of the casing by means of the crank 39 and rack and pinion devices before described. By said movement of the pan the developed section of material is drawn out of the compartment 42 and over into the fixing parent by reference to Fig. 3 which shows the positions of the parts when the movement is partly completed. The knife-blade 29 is then actuated by means of the crank 34, as described, and the print or developed section of material severed from the section is then moved to its original position shown inFig. 2 and a further section of the material may be fed into the developing fluidand the with the fixation of the preceding print.

It will be noted that when the section of material is cut off it will fall, faceupward, upon the surface of the fixing fluid. To insure the complete and uniform immersion of the print in the'fixing bath, I provide a means for pressing the same down into the fluid, as follows: On the lid 43 ofthe'casi'n'g 8, and covering a slot therein, is disposed a slidable plate 44 which is held in suitable guides extending parallel with the slot, as shown.

Passing vertically through said late and the slot in the lid, is a stem 45, on t e lower end rollers 24 are actuated by means of the crank fluid in the compartment 41, as will be ap-.

development thereof proceed simultaneously neath the pan, the end thereof forming a After a suffiwhich is in the exposure position. The pan of which is carried a horizontally extending wire frame 46. On the upper end of the stem 45 is securedfa handle 47, and a coil spring 48 1s dlsposed around the stem within the handle and the guide stem which extends up from the plate 44, the said spring normally holding the immersin "frame 46 up against the lower side of the li 43. With the pan 40 in the normal position shown in Fig, 2, the prints may be immersed in the fixing bath by pressing the handle 47 downward, thereby engaging the immersing-frame with the print and forcing the same below the surface of the fluld. By moving the slidahle plate longitudinallyof the slot in the lid the immersin gframe may be made to reach any part of the an; I

After the prints have been immersed in the fixing bath for a sufficient time, the lid 43 may be raised and the prints manually removed from the machine. In the bottom of the casing 8 below the immersing-frame is disposed a pan 5 0 which serves to catch any drip from the said frame when the pan 40 is moved to the other end of the casing. The said pan 50 may also be filled'with water and used as a rinsing bath for the prints before removing them from the machine, the lid 43 belng raised and the prints-changed by hand from the pan to the pan 50. To facilitate removal of the pans 40 and 50 from the casin g when it is desired to clean or empty them, a

door 51 is provided in the end of the casing,

as shown. 35

what I claim Patent-is;

contain a washing or rinsing bath, without de arting from the spirit of m invention.

t should be noted that, by the form of the developing fluid receptacle, only a relatively small surface of the fluid is exposedto the a1r so that deterioration of the fluid by oxidation is reduced to a minimum. It should also be observed that by pushing the sensitized material edgewise into the de-.

veloping fluid, com letely immersing the same without there eing anything in contact therewith to prevent free access of the fluid to the sensitized surface, the print may be uniformly developed and as good results obtamed as by manipulation of the material by hand.
