lighting means to be replaced in a simple and cheap manner and permits the use of a larger or smaller number thereof as desired.
An embodiment 'of the invention is illustrated by the drawing, in which Fig. 1 is a front view and Fig. 2 a cross section along the line A-B of Fig. 1. I
The spectacles consist of two annular reflectors a connected together by a nose-bow or bridge and each provided with a concen- 90 tric view opening b.' The reflectors are of U or channel shape in cross section, (Fig. 2) and serve as a blind, and are each provided on their end walls with a'lining i of insulating material. Within the channel-shaped reflectors are disposed holders :2 adapted removably to support tubular incandescent lamps g. The connecting wires may pass between the ring 0 and the lining 2' through the nose bow. Glass protecting rings k are.
tubular incandescent lam mounted in the open ends of the channel members to protect the incandescent lamps g. The incandescent lamps are connected by flexible cords to any convenient source of electricity, such as a small battery or the like.
Claims:
1. A device of the character described, comprising a. pair of bridge-connected annular members of channel shape in cross section, a plurality of pairs of lampholders 40 secured in each of said annular members, and a tubular incandescent lamp removably supported in each pair of holders.
2 2. A device of the character described, comprising a pair of bridge-connected annular members of channel shape in cross section, a plurality of pairs of lamp holders secured in each of said annular members, a
rcmovably supported in each pair of ho ders, a glass ring closing the open end of each of said channel members, a ring of insulating materiai mounted on the end wall of each of said members, and means for supplying current to said lamps.
In testimony whereof I have aflixed my signature.
