PHOTOGRAPHIC CAMERA.

SPECIFICATION forming part of Letters Patent No. 413,861, dated October 29, 1889.

Application filed September l, 1888. Serial No. 284,316. (No model.)

To @ZZ whom, t may concern:

Be it known that l, CHARLES IV. EDDY, of NVare, in the county of Hampshire and State of Massachusetts, have invented a certain new and useful Improvement in Photographic Cameras, of which the following is a speeification.

I will describe a photographie camera embodying my improvement in detail, and then point out the various novel features in the claims.

In the accompanying drawings, Figure l is a side view of a photographic camera embodying my improvement. Fig. 2 is a centra-l longitudinal section of the same. Fig. 3 is a front view thereof with the front piece removed. Fig. e is a View like Fig. 3, but showing the parts in different positions. Fig. 5 is a bottom view illustrating' certain parts connected with the shuttermechanism, a plate or piece covering the same being' removed to expose them.

Similar letters of reference designate correspending parts inall the figures.

A designates the body ot' the camera. It is shown as consisting of a rectangular box, which may be of wood or any other suitable material. Its rear is closed by a box A', in which a number of plate-holders C C2 C5 C4 C5 CG and a front coverD are arranged. This box may be made of any suitable materialas, for instance7 wood-in rectangular form. The various plateholders may be of sheet metal, and are provided with side iianges c, suitable forholding photographic plates. As here shown, they are secured at the lower ends to pivot-rods o c cg cL c5 c, which are journaled in the sides of the box A. The front cover may also be made of sheet metal with its side and top edges turned over t0 cover the plate-holders when they are in an upright position. Then the front cover is in an upright position to cover the plate-hold ers, it will iit snugly within the front of the box. The frontcover is shown as secured at the lower end to a pivot-rod d, jonrnaled in the sides of the box.

The pivotrods of the platediolders are shown as extended through one side of the box A and bent upwardly and then inwardly. Their inwardly-bent upper extremities are adaptedto engage with holes in the exterior cover in an upright position.

surface of the adjacent side of the box. It will be seen that the plate-holders are pivoted at different levels, and that the upper ends of their pivot-rods and the holes with which they engage are arranged at dii't'erent levels. These pivot-rods may therefore be easily grasped to disengage them from or engage them with the holes. The pivot-rod of the front cover is also bent upward at one end to form a handle. It may engage with a hole in the same manner as the pivot-rods of the plate-holders; but in the present instance I have shown a catch B for securing the front This catch consists ot a rod extended through the top of the box A in the direction of the length of the `camera and having its ends bent at right angles to its main portion. The outer end forms a handle, the inner end a catch. By rot-ating the rod in one direction the catch may be made to swing over the trent cover to retain it in an upright position. The rod may be adjusted into position at right angles so as to remove the catch from the front cover, whereupon the latter may be swung into the body ot' the camera so as to rest upon the bottom of the latter. The plate in the front plate-holder will then be exposed, ready for use. Atter the use of this plate the front plate-holder may be swung downwardly onto the front cover. rlhe second plate will then be exposed. All the plato-holders may suc cessively be operated in the same manner. As they are swung downwardlyin their platen holders, the plateholders will protect them from the light.

The box A is detachably secured to the body A of the camera, in the present instance, by means of pins a, extending upwardly from plates secured to the bottom oi the camerabody and projecting rearwardly beyond the same and by means of a spring-catch a', extending from the top of the eamera-body rearwardly and provided with a hole adapted to engage with a pin o2, arranged on the top of the box A. By lifting the catch a it may be disengaged from the pin a2, whereupon the box A may be swung backwardly and lifted off the pins a.

E designates a tube fastened to the front of the body of the camera and extending inn wardly into the body of the camera. lts rear IOO portion is provided with longitudinal slots e at opposite points. Within this tube E a lens-tube F is fitted so that it may slide forwardly and backwardly. Pins f extend from opposite points of this lens-tube through the slots e of the tube E. Thelens-tube F is preferably lianged at the ends, so that a packf ing of soft material g may be fitted between it and the tube E to effectually exclude light between the tubes.

Gr designates a lever consisting of a rockshaft portion g', journaled within the body of the camera', an arm g2, extending upwardly within the camera-body and having a iianged upper extremity engaging with the pins f of the lens-tube, and an arln g3, affixed to the rock-shaft portion g outside the camerabody. By oscillating the arm g3 the lenstube may be shifted into different positions. The arm g3 may be resilient and provided with a pin g4 for engaging with a number'of holes 7L h2 h3 72,4 71,5716 in the exterior of one of the sides of the camera-body. By fitting the pin into different holes the lens-tube may be adjusted so as to set the plates inthe different plate-holders. As these plates will be at different distances from the front of the camera-body, an adjustment of the lens-tubes such as I have provided will be necessary under ordinary circumstances. Obviously, the arm g3 may be manipulated for the purpose of focusing, because this construction does not make it necessary to adjust it merely in the manner first explained.

The shutter mechanism shown in the drawings is not claimed herein; but I reserve the right to claim and fully set forth that part of my invention in another application. The said shutter mechanism may be herein briefly described as follows:

The shutter l consists, essentially, of two similar end portions i t2, joined together as at t3, and pivoted on the screw i to the camera-body. An arm I is connected to the portion is, and a spring l2 engages said arm and also with a disk I4, which is connected to the camera and has an arm i5 in engagement with a lever l5, fulcrumed on a screw 6 and engaging at its free end with a projection I-6 on the camera. Pins 7 is are provided on the shutter to engage at certain times with catches 9 il", which are' arranged on a bar 11,controlled by a spring t. A pin 13 on the bar t engages a bar 18, which slides on a pin 14, and an arm 15 is provided to move the bar to release the shutter. Covers A2 A3 are provided to hide the parts above described, the front cover being secured by a catch A4.

lVhat l claim as my invention, and desire to secure by Letters Patent, is

l. The combination of a number of plateholders pivoted in place at different levels at their lower ends, so as to be capable of swinging forwardly into a horizontal or rearwardly into avertical position, substantially7 as specified.

2. The combination of a number of plateholders respectively pivoted in place at their lower ends at different levels, and a front cover therefor also pivoted in place on a pivot-rod journaled in t-he box, substantially as specified.

3. The combination of a number of plate- 'holders respectively pivoted in place at their Witnesses:
