'ROTATABLE SIG NALQLAMP.
SPEGIFIGATION forming partof Letters latent No. 519,496, dated May 8, 1894.
Applioation'filed January 5 1894. Serial No. 495,806. (No model.
This invention relates to a rotatable rail way signal lamp, provided with a removable foot or base, by which the bracket-ring is secured to the body of the lamp. Thus, when the bracket becomes broken or injured, it may be readily replaced, without dividing the bracket ring or partially destroying the lamp, as was heretofore necessary.
In the accompanying drawings Figure 1 is a vertical central section through the lower part of my improved lamp. Fig. 2 is a hori-' zontal section on line :13, m, Fig. 1, and Fig. 3 it section through the joint between lamp and oot.'
The letter a, represents thebody of a railway signal lamp, provided with a contracted neck a, which in turn is provided with an.
inwardly extending annular flange a b is the foot or base, which is made in a separate piece from the body of the lamp, and is on top, provided with the contracted neck I), and the inwardly projecting annular flange 11 The flanges a b are connected by screws embraces the necks a, b. When this bracket becomes broken, as sometimes happens, it is only necessary to unscrew the base from the body of the lamp,when the ring d, is free to he slipped off the neck a. The bracket is then replaced and the base is re-attached, whenall parts are again in proper working order.
In order to lock the lamp in its various signaling positions,'the ring d, is provided with notches d adapted to be engaged by spring catch 6, that passes through a perforation of neck b, and is operated by an elbow lever e, pivoted to the usual cross bar or handle e that extends diametrically across the base.
To set the lamp, the elbow lever e, is depressed to withdraw the catch e, from its notch, and then the lamp is revolved, until the catch engages the other notch desired.
What I claim is- The combination of a lamp having a divided neck, to constitute a removable foot, with means for attaching the foot to the upper part of the neck, a surrounding bracket ring, anda catch moving substantially in a horizontal plane and adapted to lock the lamp in its signaling positions, substantially as specified.
