CHARLES C. KIEFER, OF URBANA, OHIO.

STREET- LAMP.

SPECIFICATION forming part of Letters Patent No. 275,219, dated April 3, 1883.

Application filed June 30, 1882. (No model.)

To all whom it may concern:

Be it known that I, CHARLES C. KIEFER, of the city of Urbana, in the county of (Jhampaign and State of Ohio, have invented a new and Improved Device for Attaching Glass Globes to Street and other Lamps, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a perspective view of the lamp mounted, and Fig. 2 is a perspective view of the stand on which the glass globeis mounted.

The object of my invention is to furnish a device by which glass globes to street and other lamps may be more easily and securely adjusted to the stands on which they are mounted.

This invention consists in casting a screwthread on the outer side of the lower vertical flange of the glass globe A and a screw-thread of the same pitch on the inner face of the rim of stand B, as shown at 00, Fig. 2. Said stand is made of cast-iron, and has a horizontal bar, 0, cast across its center, near its base, as seen at Fig. 2. Said barehas a holedrilled through its center, which is tapered out, so that it can be mounted upon the end of gas-pipe G,which passes up through the lam p-post.

The bar 6 is made sufficiently narrow to leave a space between it and the side of the stand, whereby the band can be easily inserted within the globe for the purpose of lighting or turning off the gas from the burner D. The stand 0 is also raised far enough above the top of the gas-post to admit the insertion of the hand, as just explained. 0n the upper flange, E, of the globe I place a cap of any desired construction.

By this form of construction I provide a street-lamp in which thelight is not obstructed by the frame, as in ordinary street-lamps. Moreover, as the globe is elevated above the end of the lamp-post and is open at its lower end, the post itself is surrounded by light,

thus avoiding the deep shadows immediately 5 around the post, as is generally the case. Finally, as there is no door to the lamp, it is not liable to accidents by the swinging back and forth of the door, and the gas is not extinguished by gusts of wind.

I am aware that street-lamp globes have been constructed in two sections,joined together by a central band or ring, such globes being open at the bottom and supported above the top ot'the post by rods attached to the band, uniting the two sections, and to the top of the gas-post. I am also aware that globes for street-lamps have been made in two sections, united by a fastening-band, the lower section being directly attached to a block on top of the gas-post. Such forms of construction I do not claim, as my globe is made in one piece, is raised above the top of the post, and is attached to the stand, which is held by the gas-pipe without the intervention of auxiliary rods or supports.

Having thus described my invention, what I claim is 1. In a street-lamp, the combination, with a glass globe, A, having an upper and lower screw-threaded flange, of a screw-threaded stand, B, provided with across-bar, 0, through i which the gas-pipe passes, suflicient space being left between the sides of the stand and bar and between the stand and top of the gas-post for the insertion of the lighter into the globe,substantially as and for the purpose set forth.

2.. In a street-lamp, the stand 13, provided with a cross-bar, e, for the passage of the gaspipe, and an interior screw-thread forthe reception of the globe, substantially as shown and described, and for the purpose set forth.

CHAS O. KIEFER.
