SPECIFICATION forming part of Letters Patent No. 767,021, dated August 9, 1904,
Application iiled December 19, 1903. Serial No. 185,889- (No model.)
To all whom. it muy concern:
Be it known that we, ALBERT L. SwAETz and ALBERT R. MARTIN, citizens of the United States, residing at Junction City, in the county of Lane and State of Oregon, have invented certain new and useful Improvements in Multiplying Attachments for Cameras; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
Our invention relates particularly to an attachment for photographic cameras whereby a number of exposures may be made on one plate, so that what are known as stamp-pictures may be readily taken with an ordinary camera, but includes also novel features with? respect to plate-holding devices and means to shift the ground glass and plate-holder with respect to the focal line.
A further object is to provide a frame for holding diiferent-sized plate-holders, whereby smaller plates may be used than the particular camera is designed for and the use of kits therefore dispensed with.
The invention comprises a box which is' secured to the rear end of the camera, said box containing a horizontally-slidable carriage in which a focusing-glass is secured and which also carries the plate-holder. The box has the usual exposure-opening, in which an apertured vertically-adjustable cut-out slide is placed. Proper manipulation of the plate-holder and cut-out slide exposes successive parts of the plate in both directions, so that several rows of pictures may be made with one plate. An index is provided for the plate-holder carriage and cut-out slide to facilitate the proper manipulation of the parts.
With these and other objects in view the invention consists in an arrangement and combination of parts hereinafter described and claimed, and shown in the accompanying drawings, in whichi Figure 1 is a rear elevation showing the focusing-glass in position for use. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1.
Fig. 3 is a vertical section on the line 3 3 of Fig. 1. Fig. 4 is a rear elevation with the focusing-glass removed from the exposure-opening and the plate in proper position for exposure. Fig. 5 is a horizontal section on the line '5 5 of Fig. LI. Fig. 6 is a front elevation showing the attachment for Fig. 7 is a vertical section on the line 7 7 of Fig. 6. Fig. 8 is an elevation of the plateholder and its frame. Fig. 9 is a horizontal section on the line 9 9 of Fig. 8. Fig. 10 is a perspective View of the frame for the plateholder.
Referring specifically to the drawings, 12 indicates a box which is secured to the rear end of the camera in any suitable manner and has -an exposure-opening 12 in front. The rear side of the box has an opening 13, which registers with the exposure-opening and can be closedby a shutter 13a, slidable ina frame 13b, which is grooved to receive the tongues 13 on the shutter. The tongues extend around three sides of the shutter, so that when it is closed a light-tight joint is had. Vithin the box is mounted a horizontally-slidable carriage 111, having a focusing-glass 15. The carriage tits snugly in the box and is provided with guide-ribs 14, fitting in grooves 14", formed in the walls of the box. A frame 16 is secured to the carriage adjacent to the focusing-glass, in which frame is supported a removable frame 17, which carries the plateholder 18. A metal strip 19 is secured to one side of the frame 16 and has at its free end a pin 19, extending through a slot QOAin the rear side of the box. The slot has a scale Q0 along its edges. The pin 19 is provided with a knob 19, which may be taken hold of to shift the carriage back and forth. The knob has a pointer 19C to cooperate with the scale 20, as will be hereinafter described. The metal strip 19 also serves to exclude light through taking stamp-pictures. Y
the slot. The upper edge of the box has an opening' provided with a door 21, through access may be had to the carriage to insert or remove the plate-holder therein.
Around the exposure-opening 12u a rectangular frame 22 is secured to support the cut-out slide 23 and a plate 211 for reducing the exposure-opening. The lower side of the IOO , 17, joined by frame is grooved on the inside, as at 22a, to receive the lower edge of the plate 24, and the face of the plate is thickened, as at 24, to t snugly within the exposure-opening,whereby a light-tight joint is had. The upper and lower sides of the frame 22 have alined vertical slots 22b therethrough to receive the cutout slide. The edges of the slide fit in grooves 24b in the edge of the plate 24 and a strip 25 at the opposite edge of the exposure-opening. The cut-out slide has lan exposure-opening 23l and notches 23b along one of its edges. The notches-are numbered and are adapted to be engaged by a catch 25, which is pivoted on the upper edge of the frame 22 for a purpose to be hereinafter described. It is obvious that the size of the picture and the number of exposures desired may be varied by changing the cut-out slide and the plate 24.
The plate-holding frame 17 comprises sides a bottom piece 17 b. It is open at the top, so that the plate-holder, may beinserted. The sides are grooved on the inside, as at 17C, to receive guide-ribs 181on opposite edges of the plate-holder. A rib 18h extends across both faces of the plate-holder, near the top thereof, to exclude light from the plate when its side is removed.
The object of the frame 17 is to utilize small-size plates and plate-holders, if necessary. Thus the carriage 14 will preferably be of a size to receive alarge-size plate-holder.`
To use a smaller one, the frame 17 is inserted to reduce the opening and iit it to the smaller plate-holder. Obviously several such frames may be made to adapt the device to the ordinary plate sizes.
In use the plate-holder is inserted in the carriage 14, the frame 17 being used, if necessary. The door 21 is then closed and the shutter 13 opened for focusing, the ground glass 15 exposure-opening. After focusing, the shutter 13 is closed and the knob 19b taken hold of and pushed along to the end of the slot 20, by which the carriage 14 is moved forward and the plate-holderis located in proper position before the exposure-opening. After the exposure is made the carriage is moved back.
to its original position, and the plate-holder can then be removed through the door 21.
To take stamp-pictures,the plate 24 is placed in the frame 22 and the cut-out slide inserted through the slots 221. justed so that the catch ter focusing as before 25 lies in slot 1. Af-
the carriage 14 is moved forward until the pointer 19e coincides with 1 on the scale 20a.

being in proper position before the having an exposure-opening,
The slide is then ad-j The exposure is then4 shoved down until the catch engages slot 2. The carriage is in the meantime returned to its original position, after which it is ready to be moved forward for another row of exposures, as before.
Having thus described our invention, what is claimed as new, and desired to be secured by Letters Patent, is`
