PEO'IOGBAPHIC ENLABGDN'G, REDUCING, REPRODUCING, AND PRINTING APPARATUS.

Application filed October 4, 1924, Serial No. 741,623, and in Great Britain November 29, 1923.

I T The present invention relates to a simple, efiicient and cheap to manufacture self-contained apparatus which will function for all the following processes viz -Enlarg1n re- .5 ducing, reproducing, printing on (p otographic paper, projecting and repro ucing pictures or opaque articles placed in theapparatus, in black or colours, d1rectly on to the paper or glass, either ordinaryplates or colour plates (auto-chrome), the simultaneous production of a multiplicity of p ctures on one paper or plate, the production of stereoscopic photos for medical and surgical "purposes, the production of. radiography 1 X-ray negatives) on paper or on plates and t e direct taking of an ordinary photograph;

the above qualities are independent of natural light and are performed by the apparatus in any ordinary studio fitted or provided with electric current, with rapidity,

' exactitude and extreme simplicity.

In order that the said'invention may be the more readily understood, reference is to be had to the following description and accompanying sheets of drawings wherein:-

Figure v1 is a front viewof the apparatus as it appears when closed in. I

Figure 2 is a similar view, but with front door open.

Figure 3 is a sectional lan view of the apparatus, drawn to an en arged scale, and taken on line 1, 1 of Figure 4.

Figure 4 is a vertical sectlonal view, as

viewed from the front, of, the apparatus arran ed for enlarging.

igure 5 is a vertical sectional view, taken on line 2, 2 of Figure 4. Figure 6 is a view similar to Figure 4, the apparatus being arranged for reproducing pictures or opaque articles.

Figures 7 and 8 are vertical transverse sectional views of the apparatus as seen in opposite directions.

Figure 9 is a plan view of the removable lens-carrying plate for the simultaneous production of a multiplicity of pictures.

Figure 10 is a vertical sectional view of the apparatus arranged for taking a stereoscopic photo for medical or surgical pur-v slidable and removable bottom 7.

In the lower part of the cabinet 3 there is slidably arranged a light-carrying box or chamber 8, the same being provided with a hinged front panel 9 and a slidable and removable bottom 10, and between said box of chamber 8 and the top of the cabinet 3 there is slidably arranged a board 11 which carries the usual lens, or it may be lenses, 12, said lens-carrying board 11 being connected to the plate-enclosing frame 13 by means of a bellows 14.

On the underside of the removable top 15 of the light box or chamber 8 are arranged four white glow bulbs 16, see Figures 5 and 6, and hingedly mounted on the back of said box 8 is a projector glow bulb 17, the same being disposed centrally therein, said top 15 also carrying a centrally disposed depending shade or shield 18.

The light chamber box 8 is carried by a slide member 19, Figures 3, 4, 6 and 8, and is adapted to be raised and lowered by means of a pinion 20, actuated from the exterior by means of a hand wheel (size wheel) 21, said pinion 20 engaging a rack 22 on the slide member 19 which works in a slideway 23,,a clamping block 24 provided with a screw 25 being drawn tight aga'nst the side'of the rack 22-and the wall of the cabinet 3 by means of a nut 26 to lock the light box or chamber 8 in its adjusted vertical position.

The lens-carrying board 11 is carried by a slide 27 adj ustably mounted in an outer slide member 28, see Figures 3, 5 and 7 and locked thereto by means of a clamp 29 drawn against both members by means of a Wingnut 30 and screw 31, said lens-carrying board 11 being raised and lowered by means of a pinion 32 actuated from the exterior by means of a handle 33, said pinion 32 engaging a rack 34 carried by the outer slide member 28 which slides in a guideway 35, the lens-carrying board 11, by its slide member 28, bein locked in its adjusted position by means 0% a clamp 36, drawn tightly against the side of the rack 34 and the wall of the cabinet 3, by means of a nut 37 engaging the screw 38 of said clamp 36.

Further, the lens 12 is carried by a plate 39 which is removably positioned in the lenscarrying board 11, which lens-carrying board 11 also carries two removable glow bulbs 40 and 41, the one bulb being of orange colour and the other red.

In use, and when enlarging, see Figures 4 and 5, a condensing lens 42 carried by a board 43 is placed on top of the top board 15 of the camera box and centrally in the shade or shield 18, the plate carrier box 13 carried by the bellows 14 resting on said lens board 43. The lid 5 of the cabinet 3is raised and a ground glass panel isplaced on top of the transparent glass panel 6, masks as required being placed around the ground glass panel. The negative in its carrier 44 is placed in the plate-enclosing frame 13 and above a ground glass or diffuser 45 which removably covers the condensing lens 42, the ground glass or diffuser being used or not according as a soft or sharp outline is to be given. The projector bulb 17 in the box 8 is now swung to its out position below the con densing lens 42 and current is switched on by manipulating the switch 46, Figures 1, 2 and 12, lighting up said bulb 17 and also the bulbs 40 and 41 carried by the lens-carrying board 11, and the exact size of the enlargement is obtained by actuating the size wheel 21, raising or lowerin the camera box 8 containing the projector bulb 17, said box 8 bemg painted interiorly white, whilst correct focussing is obtained by actuating the focussing handle 33, raising or lowering the lenscarrying board 11, the picture being viewed on the ground glass from above. 7

The projector bulb 17 is then swung back, breaking its circuit and also that of the glow bulbs 40 and 41, and the ground glass panel on top of the transparent glass panel 6 in the top of the cabinet is removed. A sheet of paper of the required dimensions and also appropriate maskin'gs is then placed on the glass panel 6, the lid 5 is then shut down, the projector bulb 17 is swung outwards, closing its circuit and also cutting in the glow bulbs 40 and 41.

When reducing, the process is as above set forth with the exception that the size wheel is actuated in contrary direction.

When reproducing a photograph, document or other opaque article,.the condensing lens 42 and its carrier 43, and, if required, the diffuser or ground glass 45, is removed, and the projector bulb 17 is swung backwards, as shown in Figures 6, 7 and 8. The object to be photographed is then placed on the bottom 10 of the box 8 and the door 9 thereof closed as well as the door 4 of the cabinet 3. The switch 46is then switched on, lighting up the glow bulbs 40 and 41 and the. four white glow lampsv 16 are then switched on by manipulating the switch 47, see Figures 1, 2 and 12. For the rest, the operation proceeds exactly, as before. The reproduction of the opaque articles can be carried out in black, or in colours; for colours, it is only necessary to remove the transparent glass panel 6 at the top of the cabinet 3 and substitute an auto-chrome screen in lieu thereof.

Photographing on bromide paper by con tact is effected by this apparatus with greater facility than obtains with present-day apparatus; all that is required being the removal of the plate 39 which carries the lens 12, and the placing of the negative on the transparent glass panel 6, masking the remainder of said glass panel 6, if necessary. The paper is then placed on the negative and the lid 5 of the cabinet 3 closed down on to said paper, and the projector bulb 17 and the glow bulbs 40 and 41 switched on and off as requiredin the same manner as obtains with enlarging and reducing.

In fact, by the use of this apparatus, it is possible to reproduce negatives of any size, limited, of course, by size of apparatus.

The glow bulbs 40 and 41 are used for centering the aper or plates on the transparent glass panel 6 on the top of the cabinet 3, the oran e bulb beingbused when printing on plates; 1: e red bulb eing used when rmtmg on paper, the one or the other bu b being removed as required, or both bulbs may be used simultaneously.

In the event of a multiplicity of photos on a single paper bein required, say, for passport purposes, then t e slate 39 carr ing the usual lens 12 is remove from the enscarrying board 11 and another plate 38' fitted, say, as shown in Figure 9, with six lenses12substituted in lieu of the plate with said single lens.

When using the apparatus for obtainin a stereoscopic picture for medical or surgical purposes, the bottom 7 of the cabinet 3 is removed, as is also the bottom of the camera box 8, and said cabinet 3 is placed, as shown in Figure 10, on a trestle 48 and over an opening 49 therein and the patientrun on awheeled stretcher 50 to beneath said opening 49, the trestle 48 being provided with suitable draping 51, black, to cover in the patient or the injured part of said patient.

With this arrangement, the lens-carrying board 11 is fitted with plate 39' carrying two lenses 12, and the bottom 14 is divided by a central and foldable partition 52, the condensing lens 42 and difiuser 45 removed, and the patient illuminated by the glow bulbs 16 of t e box 8, and for viewing, sizing and focussing, the operator stands on the trestle 48 and proceeds exactly as before.

Further, by providing the cabinet 3 with a trunnion 53 on opposite sides thereof, an mounting said trunnions in a standard 54, said cabinet 3 can be swung into an horizon tal position, as shown in Figure 12, 'for taking a hoto of anyone placed in front of said ca inet, the individual who is to be hotographed being illuminated by arti cial light. In this case, the cabinet will be arranged with its bottom end facing the individual, the bottom17 of said cabinet 3 and the bottom of the light box 8 and the to plate 15 thereof, as well as the condensing lens 42 and shield 18 being removed, and the frame 13 fixed to box 8 and the cabinet 3 locked in adjusted position by means of a hand-screw 55 clamping the jaws of the standard 54 on to the trunnions 53, or any other convenient means may be employed for the locking purposes.

For the purpose of obtaining bigger enlargements, it is possible to arrange the apparatus upside down.
