Specication of Letters Patent.

Patented Mar. 4L, 1919.

Application led March 2, 1917. Serial No. 151,874.

To all 'whom t may concern:

Be it known that I, JAMESr OHRT, a subject of the Emperor of Germany, resident of Paxton, county of Ford, and State of Illlnois, have invented certain new and useful Improvements in Signal-Lamp Caslngs, of which the following is a specication.

My invention relates to improvements 1n lamp casings, particularly to lamp. casings principally intended for use with signals at railroad crossings. l

Itis the object of the invention to provide a lamp casing in which signals, displayed upon the transparent walls of the casing, are illuminated by lamps within the casing and located in a circuit with a battery also arranged within the casing, and adapted to glow upon the closing of the circuit by means situated outside of the casing, and adapted to be operated for instance by a moving train.

These and other similar objects are attained by the novel construction and arrangement of parts hereinafter more fully described and shown in the accompanying drawing, in which:

Figure 1 shows a lamp casing constructed according to the present invention with the cover removed, in section on line '1 -1 of Fig. 2.

Fig. 2 is a transverse sectional view taken on line 2-2 of Fig. 1, and

Fig. 3 is a side elevational view showing one exterior wall of the casing withl a signal displayed thereon.

The lamp casing according to the present invention includes a frame 20 adapted to be suspended in any suitable manner, and bearing on its transparent walls signals, for instance as shown, the word Stop or a similar inscription, adapted to call the attention of people about to cross a railroad track to the proximity of an approaching train, etc,

The frame 20 is preferably made rectangular as shown, and the casing formed thereby contains a plurality of battery units 22, and a bracket 21 secured to the upper side of the casing spaced therefrom. One

end of the bracket 21 is extended to the side wall as shown at 26 and is in engagement with the upper wall. Alining openings in the upper wall of the casing and bracket are closed by insulated blocks 27 having recesses therein engaging opposite sides of the casing and bracket, and sleeves 28 of insulating material pass through the openings in casing and bracket and their ends are located within the recesses formed in the blocks. Lamps 24 are secured in suitable sockets in the bracket 21, and a conducting wire 23 connects the lamps with the battery units in the well known manner, while one of its ends is guided through one of the sleeves 28 to a binding post 29. A conductor 31 connected to the battery units is also passed through a sleeve 28 to a binding post 30 at the outside of the casing. Other conductors 25 and 32 are secured to said binding posts, so that any convenient means located outside of the casing may be used for closing a circuit over the lamps within the casing, which closing means may for instance be operated from an approaching train in any well known manner.

Having thus described my invention, what I claim is:

In a device such as described, a casing, a bracket secured to the upper side of the casing spaced therefrom, one end of the bracket extending to the side wall 0f the casing in engagement with the upper wall, said bracket and upper wall having alining openings therein, insulated blocks having recesses therein engaging opposite sides of the casing and bracket, sleeves of insulating ma terial passing through the openings in the casing and bracket, with their ends in the recesses in the blocks, lamps carried by the bracket, batteries within the casing, a conductor connecting the lamps and batteries, and conductors leading from the batteries and lamps through the sleeves, as and for the purposes set forth.

In testimony whereof I have affixed my signature this 13th day of February, 1917.
