This inventionrelates to negative-develop ing and printing devices, and more especially to that class of such devices that provides for contact printing while the negatives are still wet by reason of a developing process.

The objects of the invention are to provide an automatic negative-developing device, having parts relatively movable, and of which one part holds negative material previously exposed, and the other part automatically dispenses developing fluids to develop the negative material during the relative movement of the parts; to provide a combined negative-developing and printing device of parts relatively movable and of which one part holds, hermetically sealed, sensitized material in contact with negative material previously exposed, and the other part automatically dispenses developing fluids and provides a light-beam to respectively develop the negative material and print the image, thus developed, upon the sensitized material during the relative movement of the parts; to provide for such a device a support defining a path for the travel of a movable part adapted to carry a hermetically sealed holding means for sensitized material in contact with negative material previously exposed; to provide for such a device a support defining a path for a movablepart and providing at intervals, along one portion of the'path, means for dispensing developing fluids, and vproviding illumination for the other portionof thepath to provide for such a device, a support defining paths, fora movable part, upon different elevations, and providing an elevator adapted to connect said paths; and to provide such .paths and elevator with means for moving a movable part of the device along both paths. With these and other objects in view as may become apparent from the vwithin disclosures, the invention consists not only of the particular form herein pointed out and illustrated by the drawings but readily admits of certain modifications withinthe scope of what hereinafter may be claimed.

While the character of the invention has a broad application to the art of photogra- Serial No. 564,068.

The improvement about to be disclosed is somewhat related to two (so-pending applications for Letters Patent, both applications having been filed by the petitioner July 13, 1931, for improvements in the process of producing photographic proof prints, Serial Numbers %,541 and 550,542, in that the loasined olampingi'rame, hereinafter described as part oi the improved negativedeveloping and printing device, is illustrated and described as an important feature in both processes for which applications were thus made.

Referring more particularly to the drawings, the support 1 may be of any desired form or structure that provides the

interior floors

2 and 3, and defines the

paths

4 and 5, respectively, of which one path is darkened and the other is illuminated and both paths are upon the same or different

elevaand n

10, and 11 and 12, respectively, a sprocket wheel 13 being fixedly mounted upon the same shaft 15 that carries the sprocket wheel 12, the sprocket wheel 13 havin an endless chain connection with an electric motor 14 by which power may be transmitted to the endless chain 8. Fixedly mounted u on the same shaft 16, as the sprocket w eel 11, is the gear wheel 17 in permanent mesh with the gear wheel 18 fixedly mounted upon the shaft 19, both

shafts

16 and 19 being mounted in parallel relation, one with the other, upon the floor 3, the shaft 16 projecting exteriorly of the support 1 and there provided with a fixed}? mounted sprocket wheel 20 having an en less chain connection with the sprocket wheel 21 fixedly mounted upon the shaft 22 journaled in the bracket 23 and fixedly carrying the gear wheel 24 for a purpose to be explained. The shaft 19 projects exteriorly of the support 1, upon the opposite side of the support to that upon which the shaft 16 projects, and is there provided with a fixedly mounted sprocket wheel 25 having a chain connection with the sprocket wheel 26 fixedly mounted upon the shaft 27 j ournaled in the bracket 28 and fixedly carrying the gear wheel 29 also for a purpose to be explained. The projecting shaft 19 is also provided with the sprocket wheel 30 having an endless chain connection with a sprocket wheel 31 fixedly mounted upon an exteriorly projected portion of the shaft 32 upon which the sprocket wheel 9 is mounted and thus transmitting to the endless chain 7 a movement opposite to that transmitted to the endless chain 8 by the motor 14. The elevator 33 is suspended by the cable 34 supported by the pulley wheel 35 mounted upon the standard 36 mounted upon the support 1, a weight 37, attached to the opposite end of the cable 34, being sufficient to maintain an unloaded elevator 33 in an elevated position at the end of the path 4, the elevator having side flanged portions 38 slidably engaging within the vertically extending slots 39 provided by the support 1, one of the slots 39 being illustrated bythe Fi ure 5. Mounted interiorly upon either si e of the elevator 33 are the spaced tracks 40, and intermediate of and below said tracks 40 is the pinion 42 fixedly mounted upon the shaft 43 of which both extremities project exteriorly of the elevator 33 and upon said extremities are fixedly mounted the gear.

wheels 44 and 45, respectively, the ear wheel 44 being meshable with the gear w eel 29 for operation in one direction when the elevator 33 is in its upper position upon the level with the path 4, and the gear wheel 45 being meshable with the ear wheel 24 for operation in the opposite irection when the e evator 33 is in its lower position u n the level with the path 5, the paths 4 an 5 each having u n its sides the tracks 46 in longitudinal a ignment with the tracks 40 of the elevator 33 when upon their respective levels. The conveyor 47 is a movable platform or container having exteriorly the rollers 48 adapted to run upon the

tracks

46 and 40, the conveyor 47 having u 11 its bottom the pin 49 for engagement y any of the multiple upright structures 50 provided by the

endless chains

7 and 8 thus adapted to move the conveyor 47 along either of the

paths

4 or 5 as the conveyor 47 is placed upon the tracks 46. The bottom of the conveyor 47 is also provided with the rack 51 for engagement by the pinion 42 to move the conveyor 47 upon the tracks 40 of the elevator 33 as the conveyor 47 approaches the elevator 33 in its upper position upon the level with the path 4, or to move the conveyor 47 out of the elevator 33 onto the tracks 46 of the path 5. The conveyor 47 is provided with the rockable tray 52 pivotally swung overhead by means of the shaft 53 fixed to said tray 52 and extending throu h the bores 54 with which the ends 55 of t e conveyor 47 are provided, one or both of the shafts 53 extending beyond the bore 54 and having fixed thereto the

arms

56 and 57 varying slightly in the length and direction. As the conveyor 47 is moved along the path 4, the longer. arm 56 slides along a rail 58 with which the side of the path 4 is provided, the arm 56, and hence the rockable tray 52, being suddenly and repeatedly operated by the contact of the arm 56 with multiple short series of slight projections 59 provided by the rail 58- in the path of said arm 56, the arm 57, and hence the rockable tray 52, bein operated at predetermined intervals by t e greater projections, one of which is illustrated by the Figure 13, as at 60, to tip the tray 52. The tray 52 is adapted to carry the clamping-frame 61 comprising the base-plate 62 of which the inside surface 63 is made of arcuate form and provided with a flexible mat 64 preferably made of rubber and yielding to said arcuate form of the surface 63. Upon the mat 64 is placed any sensitized material,

preferably printing-out paper (not illustrated), 1n contact with the film or other negative material (not illustrated) which has been previousl exposed photographically. A flexible rame 65 is then placed upon the negative material and a rigid marginal frame, 66' having the center structure 67 is laced thereon exposing the face of the negative material within the rigid frame 66.

A clamping-bar 68, having an intermediate threaded bore 69v with a thumb-screw 70 therein, engages its extremities within the interfaci slots 71 provided bythe baseplate 62, e thumb-screw being adapted to be screwed down upon the center structure 67 and thereby forcing the mat 64 and flexible frame 65, to ther with the material thus mar inally hel to assume the arcuate form of t e surface 63 and maintaini the sensitized material hermetically seal to be water-tight, the assembled clamping frame device providing a basin within which the face only of the negative material is exposed. The support 1 is provided with the

h uid containers

72 and 73 adapted to hold developing and fixing fluids, respectively, the containers having

conduits

74 and 75, respectively, with

outlets

76 and 77 at spaced rtions of the path 4, the

conduits

74 and 5 having the

valves

78 and 79, respectively, each valve being spring-pressed to a normal closed condition, but operable to a momentary open condition by means of the connecting

rods

80 and 81 and levers 82 and 83, respectively, the levers 82 and'83 each being engaged by the advancing conveyor 47 along the path 4. The support 1 is also provided with the conduit 84 and thevalve 85 connectible with a water supply, the conduit 84 having an outlet 86 at a portion of the path 4 intermediate the

outlets

76 and 77 and the valve 85, normally spring-pressed to a closed condition, being operable to a momentary open condition by means of the rods 87 and the lever 88 operatively engageable by the advance of the conveyor 47 to the portion of the path 4 adjacent the elevator 33. Mounted upon the support 1 and the cable 34-are parts of the air-cushion device 89 adapted to retard the downward movement of the loaded elevator 33., The path 5 is illuminated by a vapor light 90 0t sufiicient intensity to print out the sensitized material as the conveyor 47' travels the path 5 in its connection, by means of the pin 49 engaged with one of the multiple structures 50, with the endless chain 8. The

valves

78 and 79 are of a type having the body portion 91 provided with the

bores

92 and 93, the inlet nozzle 94, the outlet nozzle 95, the yoke 96 and the spring-pressed member .97, the member 97 having at its inner extremity a rubber cushion 98 and,

at the opposite extremity, a perforation 99 for theoccupancy of the head of a lever 100, the head being intercepted by an adjusting vscrew 101, and the lever having a cam extremity 102 operable b means of the horizontal movement of a shoulder 103 provided by and carried by any convenient portion of the conveyor 47.

In, operation, the water-tight clampingframe 61, with the sensitized and negative materials therein as aforesaid, is placed u on the tray 52 and the conveyor 47 is p aced upon the tracks 46 of the path 4 where one of the uprights 50 of the endless ipiaosi chain'zm mhmspiniammmaa the Figure 13, is intermittently operated by each 0 said series sufliciently to agitate the fluid content of the basined clamping-frame 61, which content, owing to the arcuate surface 63 of its basin, is given added motion in undulating form. Upon the conveyor 47 reaching a greater projection 60, the arm 57 is operated to tip the tray 52, as illustrated in dotted lines by the Figure 13, and hence the basined clamping-frame 61, thereby spilling the content of the basin into the container of the conveyor 47. When gravity returns the tray 52 to its normal erect position andthe conveyor 47 has sufiiciently advanced along the path 4 and under the outlet 86, it contacts with the lever 88 to momentarily open the valve 85, a quantity of water thereby being delivered to the basined clamping-frame 61 to rinse the face of the negative material, exposed within the basin, as the content is agitated by the further contact of the arm 56 with series of projections 59. A. contact of the arm 57 with a greater projection 60 again tips the tray 52, together with the basined clamping-frame 61, to spill the content of the basin into the container of the conveyor 47. Gravity again restoring the tray 52 to its normal erect position and the conveyor 47 having advanced sufficiently to arrive under the outlet 77 and contact with and operate the lever 83, the fixing fluid is thereby released from the container 72 and delivered to the basin of the clamping-frame 61 in suliicient quantity, and the contact of the arm 56 with the series of projections 59 agitating the basin content as before, and contact of the arm 57 with a greater projection 60 tips the tray 52, and hence the basined clamping-frame 61, to spill the basin content into the container of the conve or 47. The conveyor 47, having reached t e elevator 33, meshes the rack 51 with the pinion 42 as the pinion 42 rotates 'by reason of its geared connection with the gear wheel 29, thereby moving the conveyor 47 onto the elevator 33 as the pin 49 is about to ride out of contact with the upright structure 50 of the endless chain 7 with which it has been engaged. The added weight of the conveyor 47 to the weight of the elevator 33 releases the elevator 33 from its upper level Ill position and breaks the geared connection of the pinion 42'with the gear wheel 29, the force of gravity in excess of the resistance of the weight 37 operating the elevator 33 downwardly while the air-cushion 89 retards its downward course until it reaches the lower level of the ath 5. Upon reaching such lower level, t e pinion 42 is automatically given a eared connection with the gear wheel 24 an is thereby rotated in its connection with the rack 51 to move the conveyor out of the elevator toward the path 5 to engage the pin 49 with one of the multiple upright structures 50 of the endless chain 8 thus adapted to carry the conveyor 47 along the path 5 under the elongated ray of the vapor lamp 9O directed upon the exposed face of the wet negative materlal as the conveyor 47 moves under the ray which prints out the sensitized material to produce thereon the image of the negative material developed as aforesaid.

The great advantage of the above-described and improved negative-developing and printing device is most obvious. To be able to place photographically exposed negative material in this device and in contact with sensitized material, and automaticall have the negative developed and the sensitized material printed out beforebeing returned to hand, makes it possible, not only for the photographer to busy himself in the meanwhile in photographically exposing other negative material, but to expedite the process of developing and printing in that it is not necessar to first dry the wet negative material be ore printing.

While a. specific structure is herein illustrated and set forth as providing fixed paths and a material holding member movable along said paths, the material holding member might be a darkened stationary member and the structure providing the developing fluids, the means for dispensing the same, and the means for printing might be relatively movable as regards the material holding member, or the
