MAGIC LANTERN.
SPECIFICATION forming part of Letters Patent No. 449,386, dated March 31, 1891.
Application filed November 20, 1890. Serial No. 372,006. (No model.)
1'0 all whom it may concern.-
Be it known that I, FREDERICK SCHEIDIG, a citizen of the United States, residing in the city, county, and State of New York, have invented a new and useful Improvement in Magic Lanterns, of which the following is a specification.
This invention relates to the construction of stereopticans and similar lanterns; and its objects are to provide for the use of the lanterns either in pairs as a stereoptican, or singly, as desired; to facilitate the removal of the rear condensenlens, as in case of breakage from its proximity to the light; to provide against wear of or injury to the bellows; to make the instrument, and particularly the light-inclosing case, more easily and compactly folded, as for transportation; to more completely inclose the light than hereto fore, and to provide for an easier and better adjustment of the illuminating device with respect to the condenser.
The invention by which these objects are attained comprises various novel devices and combinations of devices, substantially as hereinafter set forth and claimed.
Reference is to be had to the accompanying drawings, forming part of this specification, in which Figure 1 represents a side elevation of a stereoptican embodying the primary features of my invention. Fig; 2 represents a longitudinal sectional elevation of one of the lanterns comprising the same. Fig. 3 represents a sectional plan of a part of the said lantern on the line X X, Fig. 2. Fig. 4 is a cross-sectional view on the line Y Y, Fig. 3. Fig. 5 is a sectional plan view representing part of the condenser-shell and the light-hood when folded. Fig. 6 is a side, partly sectional, elevation of a lantern like those illustrated in the previous figures, except as to the burner, which is provided with a novel form of adjusting device. Fig. 7 is a cross-sectional view of the same on the line V V, Fig. 6. Fig. 8 is a cross sectional view on the line \V W, Fig.6. Fig. 9 is a side elevation of a lantern embodying some of the features of my in vention, but provided with an oil-burner.
Like letters of reference designate corresponding parts in the various figures.
Each of the superposed lanterns shown in Fig. 1, in use as a stereopticon, and represented in detail in Figs. 2, 3, a, and 5, is constructed alike, the frame of each comprising a front standard A, in which an ordinary objective B is held, and to the back of which are fixed longitudinal slide-rods C and a rear standard D, rigidly mounted on longitudinal tubular guides E, in which the rods 0 slide, for adjusting the front and rear standards to and from each other in a well-known manner.
'In the top of both the front and rearstandards A D of each lantern are formed steps F, and in the bottom of the said standards AD of each lantern are screws G, which are adapted to rest as feet in the steps F of the other lantern when used as astereopticau, as in Fig. l, or when either lantern is to be used by itself can be instantly lifted out of said steps F and rested on a table or other support, and in either case can be readily adjusted vertically to point the objective or objectives at the desired place. It will be seen that both lanterns being alike can be used interchangeably as the upper and lower lanterns.
The condenser-shell of each lantern is made in two transverse sections H H, the rear section H fixed at its back to the rear standard D and open in front to receive the rear lens I, which is held removably in place therein by lugs J, and a spring-arm J, attached to said shell-section and bearing on the front of the lens, and the front shell-section H, open in rear to receive the front lens K and fixed in front to the slide-holder frame L, which, with the said front shell-section, is fixed upon slide-tubes M, mounted to slide lengthwise 011 the tubular guides E. With this construction, the front lens-holding shell-section H can be readily separated by sliding it forward with the slide-holder frame L from the rear lens-holding shell-section H, to give convenient access to the rear lens I and allow of its removal and replacement by another, as in case of breakage from its proximity to the light without disturbing the rest of the instrument. Furthcr,.the sectional character of the condenser-shell prevents the transmission of heat from the illuminating device to the front lens-holding section, and hence saves the front lens from danger of breakage therefrom.
The slide-tubcs M are provided with binding-screwsN for clamping them to the tubular guides E, so that the front shell-section H, with the attached slide-holder frame, can be firmly held in place either when separated from or close to the rear shell-section ll. The slid e-tubes M are also provided with binding-screws 0 bearing on the slide-rods C of the objective, which, when the slide-tubes M are clamped to the guides E, serve the purpose of securing the objective in its longitudinal adjustment with respect to the condenser.
The slide-holder frame L and the front standard A are formed with recessed frames P P for receiving the ends of the bellows Q, the ends of said bellows surrounding and fastened to inner frames R, which are socured with the bellows ends within the recesses of the frames P, so tha the edges of the bellows are protected from injury and wear. 7
On the ends of the tubular guides E, behind the rear standard D, is received removably and adjustably an ordinary saddle S, on which an oxyhydrogen-burner S, which is here used as the illuminating device, is adjustable vertically in an ordinary manner for focusing the light.
The hood T for iuclosing the illuminating device is constructed of side plates T, hinged to the respective sides of the rear standard D, so as to fold inward against the same, and having peep-doors T back plates T hinged to the rear edges of the side plates T, so as also to fold inward against the standard D, and having a catch T for locking them to getheir when opened, and an apertured top plate T hinged to the standard D, so as to fold downward and inward upon the same, and having its draft-aperture covered by an elevated plate U to include the light.
A yielding catch V is provided on the top plate to engage a detent on the top of the standard D for sustaining thetop plate when raised. This hood being capable of being folded into a very small space, as indicated in Fig. 5, renders the lantern extremely port-* able.
To include the light at. the bottom of the hood T, an apertured plate \V, covering the bottom of the hood and havinga'longitudinal slot V, to accommodate the upright parts of the burner S, is held removably in aligned slot-s W formed in opposite sides of said upright parts of the burner.
The lantern illustrated in Figs. 6, 7, and S is like those hereinbefore described, exceptas to the novel arrangement for adjusting its burner, which is an oXyhydrogen-burner, as before. The burner S is here itself received and adjustable lengthwise on guiderods S carried by and projecting rearwardly from a transverse plate S which is mounted to slide vertically on the back of the rear standard D. Headed set-screws 5' project from the standard D through vertical slots 8'' in the plate S, to guide the plateiu its vertical movement and serve for clamping the plate in place when properly adjusted. A transverse shaft S, having a turning head at the side of the lantern, is mounted in bearings S on the plate S and carries a pinion S, which projects through an opening S in said plate and engages a vertical toothed rack S fixed on the standard D, so that by turning the shaft S the plate S and hence the burner, can be'easily and accurately adjusted in a vertical direction, while the burner itself is readily adjusted horizontally on the rods 8", as before stated.
The lantern illustrated in Fig. 9 has substantially the same novel arrangement of sectional condenser-shell and bellows-frames as before described, but is provided with an oilburner, the hood o of which is attached to the back of the standard D.
I claim as my inventionl. A stereopticon comprising two similar lantern-frames, both provided on the bottom with feet and both on the top with feet-engaging steps, the feet and steps of each fitting the steps and feet, respectively, of the other, substantially as shown and described.

two separate condenser-shell sections having independent mountings on the frame, one shell-section being mounted to slide to and from the other, and a binding-screw to hold the said sliding section in place.
