OF CHICAGO, ILLINOIS.

IMPROVEMENT lN KALEIDOSCOPIC LANTERNS.

Specification forming part of Letters PatentNo. 155,085, dated September 15, 1874; application led July 20, 1874.

To ttl 'whom t't may concern:

Beit known that I, FREDERICK HARTMANN, of' Chicago, in the county of Cook and State of Illinois, have invented a new and useful Kaleidoscopic Lantern, of which the following is a specification:

The object of my invention is to provide a kaleidoscopic lantern for store-Windows, which, from the brilliancy of'the colors reiiected in the mirror Which forms the background, will attact the attention of passers-by 5 and it consists in the combination, With a reflector having its reflecting-surface lined with mirrorfacets, of a lamp -and reector supported in the focus of the large reflector, With a cone or a cylinder, or a combination thereof, of' particolored glass, either stationary or rotating, through which the light is transmitted to the reiiector, as more fully hereinafter set forth.

Figure l is a perspective View. Fig. 2 is a longitudinal vertical section.

In the drawing, A represents a sheet-metal reflector, having a hook, A2, at the back to secure it to any suitable support in a shoW- window in a vertical position, as shown. The inner surface is set With radial mirror-facets A1, secured by sheet-metal clips a turned over their ends. These facets are disposedin three or more concentric circles, and at varyin g an gies of inclination. B is a rod projecting horizontally from the face of the reliector A below the focal plane, and on it is sleeved a support, B', for a lamp, C, in the focus of' the reiiector A. At the outer end of said sleevesupport is a small reiicctor, D, Which reflects the light of' the lamp into the large reflector A. To the smaller reiiector is secured one end of a conical casing, E, for the lamp, both being made of polished sheet metal.

A circular kaleidoscope is made of glass staves of various colors. The central portion F is cylindrical, While the outer end Fl is iiaring, and the inner section F2 conical. The kaleidoscope is supported by two yokes, b b, rising from the support B1, and which partially embrace the hoops 0 0 ofthe central section.

The colored lights transmitted through the kaleidoscope into the reiiector Al are reflected by its facets in a thousand different forms as the observer passes by, While, if the kaleidoscope be axially rotated by clock-work, or otherwise, the effect is indescribably beautiful, and cannot fail to attract attention.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, With the reiiector A Al, constructed substantially as described, of the lamp C in the focus thereof, the small reflector D, casing E, and kaleidoscope F Fl F2, either stationary or axiallyrotating in the focal plane, substantially as described.

2. In combination, the rod B, projecting horizontally from the reflector A, with the sleeve B1, the lamp C, reflector D, and a kaleidoscope, F Fl F2, in the focal plane of the reflector A, substantially as described and shown.

FREDERICK HARTMANN.
