Letters Patent No. 112,380, dated March 7, 1871.

IMPROVEMENT IN COMBINATION CAMERAS AND'DEVELOPING-BOXES.

The Schedule referred to in these Letters Patent and making parl: of thevsame.

The Camera.

This'is arranged as shown in Figure 2, the parti tion or front being broken away. 1t will be seen that the cam era and the box containing the bath-holder are connected and only separated by the carrier, -Figure 6, and shown at K, Figures 1, 2, and 3, coming down between them.

- 'The lens is fastened on a box or block, T, fig. 2, which slides back and forth, by means of a strap being attached on both sides of T and passing to each end of the camera-box, thence underneath to the arrangement for adjusting the focus, shown at U, iigs. l, 2,

'y and 3.

The BathJIoZder.

This is made .of glass or any suitable substance. It should be perfectly level at the top, and suiiiciently large to admit the dipper and plate with ease. The height should `be'abont one-quarter inch more than its receptacle in the carrier.

T he Oar/rter, Figure 6.

This is ground glass, -dark slide, bath-cover, and clipper combined in one.

J is the ground glass, and directly underneath is the dipper F, which is rmly fastened to cushion and board a.

This dipper is a common' gatta-percheJ dipper, only it has Y, Figure 7, attached to it, the whole being made in one piece, somewhat stronger than usual.

The cushion u is made of two or three thicknesses of cloth, covered with-oil-cioth; and when the carrier is pressed down on the bath this cushion forms a water-tight cover.

The top of the hack of the carrier is open, as shown in iin. 3, at J, which shows the back of the ground glass.

The front of the carrier, at the top is opened and closed by a slide, shown by dotted line, fig. 6, 'and at B, rigs. l and 2. This, however, is only opeuedwhen adjusting the focus. y

The spring H, iig. 6, is so arranged as to hold the plate in its place while exposing, and passes behind the bath out of the way when sensitizing the plate.

The small hole X, iig. 6, isA to receive the spring W, iig. 2, which holds the carrier in placewhile exposing the plate.

Separating thcUamem andBath from the Developing l Department.

This is best shown in fig. 3. The camera and bathbox are entirely closed.

O is a slide, which runs in grooves.

l? is a wire attached to O, and goes outside of the combination.

This slide is moved back and forth from the outside, and when the carrier is up the plate is opposite this slide, and by openiug't the plate can be taken out into the developing department.

This is also a combination of three parts in one, the lamp, the developer, and water. It is made of tin. The part holding the developer is coated with acidproof cement. The lantern is placed between the developer and water, with a space between them so as prevent them from becoming hot.

Frontoil the lamp' is a yellow glass, gs. 8 and 9, at z.

ci is a mirror, shown in fig. 8.

e, figs. S and 9, are two pieces of rubber hose, exn tending tothe front, and covered at the mouth watertight with two springs. Two pieces of wire coming fromoutside ci' the combination press those springs open when the developer or watcris wanted. The springs close'againof themselves.

The wires are shown at R, Figures l, 4, and 8.

The deveioper and water are putin at the top of hg. 8, shown at Q, iigs. l, et, and 8.

The lamp is aise put in at the opening shown at ll, fig. 8.

The E illeHood, Figure 5.

This is also one separate piece, and is so made that it can be turned in when not wanted, entirely ont of the way, shown in iig. 4, at E G. This hoc-ri is consirncted of cloth, the top cf which is encircled with a wire, forming an opening, as shown at Gr, iig. This wire being pliable vand springy can be adjusted so as to fit closely over the eye.

There are two small pieces of wood passing from the wire `to the traine-work, These are fastened at each end but not firm. These keep the wire in place and at the same time leave it suiiiciently springy to tit closely around the4 eyes and nose when the face is pressed ou it.

TheDoor and Pliers L, Figures 1 and d.

This is formed of oil-cloth, excepting the frame. The cloth is formed in shape of a funnel. .he pliers, madei'rom gutta-percha, are :placed in the point and hrmly tied there. Then the whole is fastened in the frame, as shown at L, iigs. 1 and 4. The whole is closed by a button fastened on the frame.

Waste-water Boz, shown at M, Figure 1.

This may be made of tin,vwell painted, and in one corner is a hole, rin'nned in such a form asto pass through the bottom of the combination, which can be corked np when working in the house, and in the tield left open so that the waste-water may run away.

Fig. et represents the combination as it is when closed, the oil-cloth cover thrown back. The strap represented in this ligure is supplied with a buckle, and is used to carry the combination by.

General Remarks.

' The position and placefor the hath-holder are ill ustrated at N, ligs. 1 and 2.

The camera can be arranged for one or two tubes, so that stereoscopic pictures can be taken. It ,also can be made of any size, the combination being made in proportion to the size oi' the picture.

The Dipper, Figure 7 Of these you can have two or three, to snit the different sizes oi' the pictures. v

The following is the mode of working with this combination.

The small lamp being in its proper place` the bath, developer, and water can be put in their places before' starting ont. AA bottle containingr collodion and one containing hyposulphite is also set in the inside of the combination, together with a small tray and cleaned plates. Now cork up-the tank or developer and waterboxes, fasten down door A,h`g. 1, adjust the oil-cloth and strap, take an empty pint bottle and put iu your pocket, together with a small box for holding negatives, and you are ready to go. 1f you wish, you can take a heavy tripod-stand with you. (I have made out without one so far.)

Whentyou get to the place you want to take, open the combination and light the lamp, nncork the tank, throw back small door A, fig. l, open the large door, draw up the carrier until it catches. Now turn the eye-hood out, as shown in g. 1, E G. Take out a plate and coat it with collodion. Withdraw slide O, rigs. 1 and 3, by pulling out the wire P, figs. 1 and 4. This exposes the dipper to view. You place the plate thereon, and then again close slide O by means of wire aforesaid. Now press ou spring W, fig. 2. This releases the carrier.' You now press the carrier down in to its irst position. Now raise slides D, B, rand O, and adjust the focus by means of focusing arrangement'U, figs. 1 and 2. By this time your plate will be sensitized. Now close slides B and O, draw up the carrier until caught by the spring, withdraw again slide C, and expose.

Then suiicieutly exposed 'press back slide G and close the door, put your head on the eye-hood, and withdraw the slide OA by means of wire P on the outside of the combination. Take the pliers and take the plate olf the dipper, and hold it under the taps. Now press on the' proper one oi` the wires R R, and the developer will 110W on the plate as nicely as if poured from a bottle. When sufficiently developed press on the other wire in the same way, and the water will wash it oti. Now, if you prefer, you can put it into the tray you brought along and throw the lizing solution over it. This tray can be kept under the camera, out of the way.

I do not find it necessary' to use this tray at all. I wash the plate well, and then take it out and coat it immediately with hyposulphite, and when suticiently fixed give it a good washing from the bottle that I have in my pocket to carry water in. I have found no inconvenience in this way ot' working.

Your negative now' only wants drying and placing in the small negative-holder and set into the combination. N ow put the carrier down, and press thc small door Afdown ou it and fasten 1t tightly in place. New extinguish the lamp and cork up the tank, close the door and fasten it, shove in the pliers, adjust the oilcloth and strap, and you are ready to go homeor for another view. \Vhen thus closed everything is perfectly tight. No bath or other solution can spill.

This combination can be kept always ready, and in ease of a call to go out to take a picture of a corpse, for instance, all that is necessary is to take up your combination and go, and when you get there you are. ready to go to work.

I claiml 1. The combining of the camera and developingbox in such manner as described,'as a new article of manufacture.

2. The combination called the carrier, and the mode of placing the dipper and ground glass therein, the whole to be used in the manner and for the purpose Set forth.

,3. The arrangement of the camera and bath receptacle in such a manner as described, for use and purpose set forth.

4. The tank for holding the developer and water in the manner and for the purpose set forth.

5. The placing of the pliers in the center of' the door, for the use and in the manner set forth.

6. The manner ol arranging the eye-hood so that the head can be tightly placed thereon without the diiiiculty of fastening it to the head, the whole to be used in the manner and for the purpose set forth.
