IMPROVEMENT IN SIGNAL-LANTERNS.

Y Specification forming part of Letters Patent No. 171,417, dated December 21, 1875; application lled May 14, 1875.

To all whom Yit may concern:

Be it known that I, GEORGE F. PAsHLEY, ofthe city of Brooklyn, county of Kings and State of New York, have invented certain new and useful Improvements in Lanterns, ot' which the following is a specification:

My invention specially relates to signal-lanterns for use on railroads and otherwise.

The invention consists, iirst, in constructing a globe-lantern with part of the globe of crystal glass, and part of lcolored glass from top to bottom.

The invention further consists yin constructing a lantern with crystal and colored glass on its opposite sides, and a reliector of semicylindrical or other shape to intensify the light on that side on which it is to be shown, and to cut it ott from the other side.

ln the accompanying drawing, Figure 1 is a vertical section of a lantern illustrating the invention. Fig. 2 is a horizontal section on the line 2 2, Fig. 1. Fig. 3 is a perspective View of the lanip and reflector.

A represents a lantern-globe of common form, constructed with one side, a, vof crystal glass, and the other side, a', of red or other colored glass. B represents the base ot' the lantern. O is a cap, hinged at c, and fastened by a button, d. F is the lamp, secured`with in the base` by spring-catches G G' of common construction. His a reiiector of semicylindrical or other suitable shape, which may be attached to the lamp, and is adapted' to intensify the light on that side on which it is to be used, and to mask it from the other side, so that only the clear light may be shown,

while the colored glass is entirely dark, or vice versa, the colored light being shown and the clear side being darkened. It is not essential to the invention that the reflector shall be attached to the lamp; but by making it as shown it is adapted to be readily turned, as required, by simply grasping and compressing the lamp-springs G.

The tin reflector acts to intensify the light on that side on which it is wanted, and renders the other side entirely dark, so that there is no possibility of displaying the wrong signal, even if the lantern be carelessly held.

'lhe device is intended, chieily, as a railroad signal-lantern, and is particularly adapted for the use of conductors, brakexnen, track-walkers, Watchmen, and others.

, l am aware that lantern-globes'have before been made with the lower and upper parts of different colors, or part clear and partcolored. This, therefore, I do not claim. By making the globe part clear and part colored from top to bottom, a new and valuable result is accomplished, as above explained.

The following is claimed as new:

The combination, in a lantern, of a globe, divided intovertical sections, clear and colored or of different colors, and a rotatable reector, by which the light may be shown through the desired color, and shut oi' from the others, in the manner and for the purpose described.
