Fig. 7 is a section on the line E-F in Fig. 5 with parts omitted. Fig. 8 is a rear view of the structure shown in Fig. 5. Fig. 9 is a View on an .enlarged scale of the magazine end pf the structure shown in Fig. 5 in a section on a vert-ical plane through the magazine and with other parts shown in elevation. Fig, 10 is an elevation of the negative holder used at the front of the structure shown in Fig. 5. Fig. 11 isa top plan .view of the structure shown in Fig. 10.

Referring to the drawings, more particularly Figs. l, 2, 3 and-4there is shown a box or` closure 1 capable of being rendered actinically light tight, though nonactinic light is permitted to enter through awindow 2 and a door 3 each of which may be provided with the usual ruby glass. The Window 2 is located on oneside of the box 1, preferably above the middle line of the box, While the door 3 may be on the other side Patented Aug'. 1, 1911. y

of the box and of a suiicient size'.t o permit I ready access to the box.

On top of the box are secure'd'-.spaced strips 4 5 and between) them there.A issecured a board 6 removably held inplace by but-tons 7 and hinges or catches 8.

' The board 6 carries an upright board 9 having a suitably located passage 10 therethrough of a size to permit a light image to pass to the sensitive plate of the largest size for which the apparatus is designed.

The board 6 has a slide extension 11 forming a track for another board 12 capable of sliding across the rear face of the board 9 in close contact therewith between the said board 9 and a guide 13 carried bythe board 6 and extending along the said projection 11 of the said board 6. The board 12 carries at the'upper edge an overhang 11 extending around the rib 15 along the upper front edge of the board I9. The board 12 is capable ofsliding along the entire length of the board 9, which 'Iatteris as long as the board 6 and side extension 11.

Fast to the board 12 near the upper edge thereof is a `magazine 15 conforming in shape in crossss'ectional internal area to the size of the sensitive plates vto be used in 'the machine. ,The end of the magazine 16 remote, from the board 12 is normally closed by a cover 17 held in place by buttons 18.

Extending through the cover 17 is a rod 19 terminating at the inner end at afollower 2O and designed to push the sensitive plates indicated at 21 against the board 12 at the point immediately above an 'opening 22 therein capable of being brought into matched relation to the opening 10 in the board 9.

The rod 19 beyond the cover 17 carries a cross head 23 to which is connected a spring 24 extending to a fixed portion ot the struc* ture, these ysprings tending to move the fol-` lower 20 against the plates 21 within the magazine.

Extending across the magazine and oh the top of the struct-nre cerryin tile nel also downward past lthe opening zin-l ending et the boord G is ot e width equal to thevlength. of tile plate 2]. und of thickness sufficient to permit e single plete et time to pass. fir- 'enge/l to enter the passage 22 to en extent s'eiiieient to traverse 'the mager/,ine 16 is e slide 26 of such thickness to the `L?" t plete in the magazine :incl push the along the passage into coincidence opening which letter is slightly l en the plete so that the plee/e may not pass through the seitl opening. f

rEhe front boe-.ral 9 of the structure has on its iront face 'two spacecl strips 27e-28, one provided with an eye 29 and the other with e .button 30 so that a camera box 8l may be secured in place by means of e lug 32 adeptecl to the eye 29 and be held by the button 30, the camera being provided With the usuel bellows 33, a lens carrier 34 and lens 35, it being; understood that any ofthe focusing means commonly employed 'With cameras muy be utilized in connection with the cem-A em shown, which showing of the cerner-e is not eonepletev since any suitable known type of meraJ may be used and7 therefore, the showin@ is made illus yrative only. The perh tieuler type of camera. indicated is 'the old- 'ingr type of camere, thus permitting this portion of the structure when remaining in position to be folded into e small compass.

The magazine 16 together with the board l2 is capable of sliding along the board 9, either to position in coincidence with the optical ot the lens 35 or to such an er@ tent to Ione side 'thereof es to expose the opening l0 to view from the rear side of the board 9. Mounted on top the overhang 'lei spring intel 36 so arrenged es to` engage stop ineens in the top of the boarcl 9 to position the boord l2 With relation to the opening l0, this being e common practice in prnti'eit cameras. The overhang le is also provided with. a spring c-Lich 3T engaging the upper encl of a trame 38 carrying' e, focusing screen 3S) preferably of ground glass, this frame heiligheidl et the bottom by :i brzici i0, the frame tli being' readily ren'lovzibm Jfrom the board when flesiroal.

When theslide 26 is depressed to cause the movement of the exposed plate into the conduit 42 the rod 47 has already been i'otated to a position to carry the frame 50 beneath the conduit 42 so that the dropping plate after passing through the conduit 42 I 1s received 1n the frame 50 and caught by the angle extensions 52 on the lower ends of the levers 51.

The rod 47 is now rotated until above the tank 45 and then the rod is depressed until the frame 50 and the plate carried thereby is immersed. in developing solution in said tank 45. The window 2 is located immediately above the tank 45 and the door 3 is high enough to be in line with the window 2 so that raisingthe rod 47 from time to time the frame 50 and the late therein Awill be elevated into line with t- 1e window 2 and I alight opposite the door 8 will enable the operator to observe the progress of the development of the plate being treated.

When the development has proceeded to the desired extent the rod 47 is elevated and turned .about its longitudnal axis until over the tank 44 and is then dipped therein, this tank containing washing water. The rod 47 is again manipulated to lift the frame 50 over the tank 44 and the rod is then turned until the frame 50 is over the tank 43when by depressing the rod the frame 50 is moved toward the tank ,43 until the stops have engaged the outturned ends 53 of the levers 51 and have caused the movement of these levers against the action of their springs 54 until the angle extensions 52 are moved out of the path of the developed plate and the latter gravitated Iinto the tank 43, whiehlatter contains av suitable fixing solution.

lVhen the plate has remained long enough in thc fixing solution the tank 43 may be removed fromthe box l through a door 56 in one side of the box in a line with 'said tank. By this means a sensitive plate ma be exposed to the light image of the lens 35 and then transferred in succession to the de-` veloping solution, washing bath and fixing bath withbut the plate being exposed to i tiiuic light and without the npcessity of king the exposed plate into a dark room.

The invention heretofore described is adapted ffii" the vproduction of negatives by the direct photography of objects.

The inventiony is also adapted for the production of copies or enlargements from negatives already produced and any of its salient features need not differ in material respects from the structure already described.

The copying camera is illustrated in 5 to 8, both inclusive.

The cop in camera is provided with a box 57 at the-front end of which there is secured a bellows 58 which in turn is made fast at the forward end to a board 59 capable of sliding between the guides 60 on a Flgs.

base-board 6l and hinged at 62 to the bottom of the box 57. Attached to the front of the board 59 is another bellows 63 secured at its forward end to a board 64 also capable of sliding' on the base 6l between the guides 60, the board 59 being mounted on a block 65 and the board 64 being mounted on a block 66 adapted to the guides 60, the entire struct-ure, so far as the base 61 has parts carried thereby, being similar to that employed usually with cameras.

Mounted on the board 59 within the bellows 58 is a lens 67 of the type usually employed for copying, although the invention does not depend in any manner upon the ty e of lens employed.

` ivoted to the front of the board 59 within the. bellows 63 is a blind 68 capable of being moved in front of the lens 67 to prevent the admission of light thereto or away from the lens to admit the light thereto, this blind being mounted on a shaft 69 extending to the exterior ofthe bellows 63 and thereprovided with a handle 70 which may be caught behind a stop pin 71 on the board 59 and when so caught the -blind 68 is in position to shut oit' light from the lens 67. The front board 64 carries guides for a plate holder 72 designed to carry the` negative through which the light is to be transmitted to the lens 67.

While not shown in the drawings, it is to be understood that the plate holder 72 may be provided with adjusting means such as are usually employed in copying cameras' forpositioning the negative with reference to the lens.

`The copying camera is designed more particularly for the making of prints from negatives upon sensitized postal cards or other heavy-paper carriers having a sensitive surface.

The rear portion of the box 57 at the upper end thereof is provided with lan openingr 73 in the focal axis of the lens 67 and this opening is normally closed by the delivery end of a magazine 74, similar to the magazine' 16 of Fig. 1 but shaped to contain postal cards or other heavy-paper carriers. This magazine is provided with a follower 7 5 mounted upon rods 7 6 extending through a .cover or cap plate 77 for the end of the magazine and the rods 76 are connected to a Cross head 78 `outside the magazine and this cross head urged in the direction to cause the follower to move toward the .delivery end of the magazine by appropriate springs 79.

The end of the magazine adjacent to the opening` 73 is also open but the opening` is larger than the opening 73, being as large as a postal card, While the opening 73 is somewhat smaller so that a` postal card will be held by its edges from passing through the opening 73. Immediately, above and below the open end of the magazine are pas sages for the slide 80 similar to the slide 26 and designed to move anfexposed postal card through the opening below the magazine into the interior of the box 57, said box being inset at the point Where the magazine is secured to it, so that the postal card in being moved from the magazine to the opening below the magazine will enter the box 57 at a point some little distance from the rear Wall thereof.

Extending through the rear Wall ofl the box 57 is a bar 81, preferably square in cross section, and carryingat the end Within the box a head 82, the purpose ot' which will be hereinafter set forth. The bar 8l on its upper end is 'formed with a series of spaced grooves 83 in any ot which may be lodged a spring rod 84 holding the bar in diierent 4positions ith the head end correspondingly v furthe-1.' into the interior' o the box 57 or closer to the rear Wall of the box as the case may be.

Extending through the rear Wall of the box are rock shafts 85 in spaced relation one to the other and 'these rock shafts carry within the box rock 'arms 86 and outside.

the box other rook arms 87, the latter carrying; ibonneeting link for simultaneous movement "while a spring 89 holds the roelarms in a predetermined position, which position is that Where the roel; arms S6 have their free ends moved away one from the other.

Extending through the top of the box near one corner thereof is a rod 90 provided at the upper end with a manipulating handle lor Wheel 91. The lower end ot the rod 90" tacle' and the partitions the postal Cards in snob. a manner as to present them to the de-4 `veloping, Washing` and fixing baths and for this purpose the side walls of the receptacle are niade of skeleton type and partition members are formed with studs or projections so that the sensitive surface of 'the ing covered by a trans .iaient 'card for a sufficienti length of ai postal cards are held away from ooi with any part of the receptacle except at. tl A studs 95 which may be close to the er the postal cards and i i` with those portions o' the which have been acted upon the The rod 90 under control of a tendingto elevate the rod-and .may also act and tend. to sold position Where the receptacle 93 nm. engagement with the head at the end of the bar 8l.

Mounted on the bottom et the bon i? tanks 97, 98 and 99 in radial relation to axs'of the rod 90. above the tar side of the box 57 is provided with a preferably of glass, of a charaeter pe ting' vthe passage ot' light which tically non-actinic to the sensiti of the postal cards or printing torthis purpose orange glass connnonwf e; ployed b photographers will be ound fieient. he opening i0() may be close L a door 10Q.

The bar 81 is released from the spring rod 84 and vthe head 82 is moved into the interior of the box 57 until the spring rod snaps into the next groove 83 from the one first engaged, thus moving the receptacle 93 so that the second compartment inthe receptacle 93 is in position to receive the second postal card discharge from the magazine on the re-insertion of the slide 80. These 'operations are repeated until the receptacle 93 is full of postal cards, if .such a number of prints are desired, and then the rod 90 is rotated against the action spring 96 until the receptacle is over the tank97, which tank is designed to be provided with a suitable quantity of a suitable developer. The rod 90 is now pushed downward against the action spring 96 until the -post'al cards within the receptacle 93 have become immersed in the developer and the action is permitted to proceed so long as the judgment of the operator may demand, but the operator may guide the'developing by releasing the rod 90 and permitting the receptacle to rise until the front one of the postal cards is visible behind the glass pane 101, the door 102 being open. When the development hasvproceeded so far as needed the rod is released so that the receptacle 93 may be withdrawn from the, tank 97 and the rod is turned until the receptacle 93' is over the tank 98 and then, on pressing the rod,

the receptacle is dipped into the tank 98,

which tank is assumed to contain Water only, for washing purposes, after which the receptacle 1s moved around until over the/ tank 99, the bar 81 having in the meantime been moved outwardly until Athe head 82 is against the inner wall of the box 57.

The receptacle 93 is provided at each end with a lever 105 like the levers 51 already described and each of these levers hasl a 'handle extension 106 like the handle extension 52 of thc levers l-andfor the same purpose, and each lever is provided with` a spring 107 like the spring 54 of the levers 51, and, furthermore, the end of each lever 105 remote from the handle extension 10G is outturned as indicated at 108 like the outturned ends 53 of the levers 51. When the receptacle 93 is above thetank 99 the outturned ends 108 of the levers 105 are in the path of the arms 86 of the rock shafts 85 and then by movingthe rock arms against the action of the spring 89 they are brought into engagementwith the levers 105, therei by causing the release of the cards which thereupon'drop through` the bottom of the receptacle 93, which' latter is otherwise unobstructed to the passage of the cards, and they are received in the tank 99 in which is a suitable quantity of fixing solution. After the lapse yof a sufficient time the door 104 may be opened and the tank 99 may be removed through the opening 1`03.

The operation may beA repeated as often as necessary until the contentsof the magazine 74 are exhausted, when the supplies. of the machine may be renewed for further operation. 4 A
