STREET LAMP. No. 391,950. Patented Oct. 30, 1888" ATTORNEYS EDXVARD A. DUBEY, OF BROOKLYN, NEW YORK, ASSIGNOR OF ONEHALF TO THOMAS E. tUTAN, OF SAME PLACE.

STREET LAh/l P.

EPECIFICATION forming part of Letters Patent No. 391,950, dated October 30, 1888.

Application tilt-d June 21, 1887.

To aZZ whom it may concern:

Be it known that I, EDWARD A. Donny, of Brooklyn, Kings county, New York, have invented a new and useful Improvement in StreetLamps, of which the following is a full,

clear, and exact description.

The objeet of my invention is to provide new and useful improvements in street-lamps.

The invention consists in the details of im- IO provement and combinations of parts, that will be morefnlly hereinafter set forth.

Reference is to be had to the accompanying drawings, forming part of this speciiieatiomin which-- Figure 1 is a side view of a street-lamp of my improved construction, part being broken away. Fig. 2 is a vertical section on the line 0 c, Fig. 1; and Fig. 8 is a horizontal section on line k 70, Fig. 2.

A in the drawings represents the lower,and B the upper,portion of a street-lamp embodying my invention. Each of those portions is constructed as follows: a a are upright wires arranged at the corners of each frame. At

2 their lower ends these wires are connected to a horizontal wire frame, 71,, and at their upper ends to a horizontal wire frame, g. Around the upright wires a a are wrapped sheet-metal standards 1), extending the length of the wires a, between the wires 9 and h, said standards having flanges or glass-rests d d, against which the pane of glass 6 e of the lantern may rest, as best seen in Fig. 3. By constructing the lampframe upon the wire foundation a g h, I obtain 5 great strength,and am furthermore enabled to use parts of the wire foundation as a hingesnpport for protecting'screens.

The horizontal wires 9 and h are carried at a little distance outward from the uprights a 0 a to allow the protecting-screens D to be hinged and held fast. Each screen Dis made of wire netting and adapted to cover one pane of glass of the lamp. The screen preferably conforms Serial No. 241,962. (No model.)

to the shape of that side of the lamp which it covers, Fig. 1. The netting of the screen 5 D is secured in a circumferential wire frame, i, which gives additional strength to the screen. The screen D is hinged to the lower wire, it, by means of links j, and is held in place against the side of thelamp by means of hooks Z,which 5o engage the upper wire, 5 of the lamp-body.

This construction makes the screen D easily adjustable, and said screen may be swung down to admit access to the glass or burner when desired. Instead of hinging the screen D to the lower wire frame, h, it may be hinged to the upper Wire frame, 9, or to the upright wires a; but I prefer the manner shown.

I prefer to make the netting of the screen D of galvanized wire, for the reason that in that case its many surfaces act as reflectors for the rays of light from the burner, thereby materially increasing the illuminating power of the lamp.

The screens D D protect the glass of the 6 lamp from injury, increase the illuminating power of the lamp, and can easily be moved out of the way for cleaning the glass and other purposes. The wire frame a9 h materially strengthens the body of the lamp and facili- 7o tates the use of hinged screens.

Having now described my invention, What I claim is l. The lamp body constructed of uprights a a and horizontal wires 9 and h, in combination with the separate screens D, hinged to the lamp-body, as specified.

2. The lamp-body and wire frame a g h, in combination with the separate screen D, hinges j, connecting the screen with the wires h, and So hooks Z, carried by the screen and engaging the wires 9, as set forth.
