UNITED STATES PATENT OFFICE.

LEWIS HOVER, OF FLUSHING, NEW YORK.

SIGNAL-LANTERN.

Specification of Letters Patent No. 25,645, dated October 4, 1859.

To all lwhom 'it may concern:

Be it known that I, LEWIS HOVER, of Flushing, in the county of Queens and State of New York, have invented a new and usei'ul Improvement in Railroad-Lanterns; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, in which- Figure 1, is a vertical central section of my invention. Fig. 2, is a horizontal section of the same taken in line Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.

This invention consists in the arrangement and combination within the lantern case and above the lamp, of a metallic cylinder and a colored glass cylinder, the metallic cylinder serving to protect the glass from the heat and smoke of the lamp, and also serving as a guide and support or fzlistening for the rise and descent of the g ass.

To enable those skilled in the art to fully understand and construct my invention I will proceed to described it. I

A, represents the case of a lantern B, a colorless glass globe fitted therein, C, the lamp attached to the base which is secured to thc case A, in the usual or in any suitable way. The case of the lantern has the usual guards a, attached to it to protect the globe B.

Within the upper part of the case A, above the glass globe B, a sheet metal cylinder D, is secured permanently. This cylinder is considerably smaller in diameter than the upper part of the case and it is slotted vertically at two opposite points of its center as shown at Z), Z). In the upper edge of the cylinder D, a little at one side ot' the slots b, I), notches or recesses c, are made, one near each slot b. The position of these notches or recesses is shown in Fig. 2, and the form is shown clearly in Fig. l, in which one notch is represented.

E is a colored glass cylinder suiiiciently large to encompass the sheet metal cylinder D, and slide freely on and olif from it. This cylinder E, is open at its lower end and it has a metal cross bar F, attached centrally to its upper end in any proper way. This cross bar F, is itted in the vertical slots b, b, oie the cylinder D, and is allowed to move freely up and down therein. The cross bar F, near its end is suiiiciently narrow to fit into the notches c, and the center portion of the bar F, is wider than the ends in order to allow a triangular opening d, to be made therein to receive the lower triangular end c, of a rod G, which passes vertically through the top of the lamp case. The lower end of the rod G, below the cross bar F, has a nut or head f, placed on it.

W hen a colored light is required the glass cylinder E, is allowed to descend and encompass the flame H, of the lamp as shown in Fig. l, and when a white light is required the rod G, is raised by grasping its handle I, and with the rod the glass cylinder E is raised in consequence of the connection oi the rod Gr, with the cross bar F, andv the cylinder E, is made to encompass the sheet metal cylinder D, the cylinder E, being supported in an elevated state by turning the rod G, so that the cross bar F, may it in the notches c, in the upper end of the cylinder as shown in red outline. The rod G, turns t-he cylinder E, in consequence of its triangular end c, fitting in the triangular opening cl, of the cross bar F. Vhen the cylinder E, is elevated the rod G, is allowed to descend within the cylinder D, and when it is desired to lower the cylinder E, the rod G, is raised unt-il its triangular end c, enters the opening d, when the rod G, is again turned so as to adjust the cross bar F, in the slots and the cylinder will drop by its own gravity and rest on arms g, on the upper part of the lamp.

It will be observed that the metallic cylinder D, serves to protect the glass E, when the latter is raised from the heat and smoke of the lamp, said metallic cylinder also serves as a guide during the rise and descentof the glass; and also as a support or fastening to the glass when elevated.

I do not claim broadly the providing of lanterns with colored glass, but;

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is-

The arrangement and combination with the case A, and lamp C, of the metallic cylinder D, and glass cylinder E, substantially as and for the purpose herein shown and described.
