ELECTRIC ARC LAMP PROTECTOR.
No. 849,999. Patented Sept. 28, 1886 NITED rArEs GEORGE JEFFERY, OF DETROIT, MICHIGAN, ASSIGNOR TO '1. P. TUITE, OF SAME PLACE.
ELECTRlC-ARC-LAMP PROTECTOR.
SPECIFICATION forming part of Letters Patent No. 3l9,999, dated September 28, 1886.
Application filed October 29, 1885.
To all whom it may concern.-
Be it known that I, GEORGE JEFFERY, of Detroit,in the county of \Vayne and State of Michigan, have invented new and useful Im- 5 provements in Electric-Arc-Lamp Protectors; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.
Thisinvention relates to certain new and useful improvements in the construction of lamps, especially designed to be employed as a protection to the electric-arc lights, and the mechanism by means of which the feed of the carbons is controlled or actuated.
It has heretofore been the practice to inclose the carbons by means of a glass globe, whereby considerable trouble was caused in charging said carbons and in keeping the lamp in order, as the upper side of the globe is open, thereby admitting snow, rain, and dirt. This trouble and labor was and is the cause of the breaking of many globes, which are costly; and it is the object of this invention to provide a lamp the employment of which will facilitate the necessary work of keeping the electric lamp in order and exclude all foreign substances.
Figure l is a perspective view of my lampincloser. Fig.2 is a cross-section on the line a: x in Fig. 1. Fig. 3 is a section on the line y y in Fig. 1.
In the accompanying drawings, which form a part of this specification, A represents a socket designed to fit upon or rest upon the support of the lower carbon in an are electric lamp. From the top of this socket there rises a frame, B, made of sheet metal, polygonal in form, flaring outwardly as it rises from its base, and of the usual construction to hold glass panes O, as is found in the construction of ordinary street-lamps, except that near the top of this part of the frame there is secured, either by being cut integral in sheet metal with the other parts of the frame or by being riveted or soldered thereto, the stops a, for the purposes hereinafter described.
Secured to the top of the frame Bis another sheet-metal frame, D, to hold the panes of 5c glass E which form two or more sides of the top of the lamp protection. Each pane of glass Serial No. 181,244. (No model.)
E has upon one side of it that portion of the frame I) which is constructed like the frame B, but upon the opposite edge of the pane the overlapping flangeb, which would hold the pane in place like the lower portion of the frame, requiring the glass to be slipped in from the bottom into the two channels. One
on either edge of the same, formed by the frame, is left off, or rather supplemented, by soldering to the frame a flange or flanges, b,
of soft metal, like lead or copper, which may easily be bent. Now, these flanges, which may extend the whole length-of this portion of the frame or be small and interrupted, as shown in Fig. l, are bent outwardly, so that one edge of the glass may be-inserted in the channel of the opposite leg of the frame and the loose edge dropped to place, as shown in Fig. 2, when the flanges b are bent by the operator over on to the outer face of the pane of glass to hold it in place. Now, to prevent this pane of glass from sliding downward, its lower edge rests upon the flanges or stops a overlapping the upper end of the pane of glass 0 below it, 7 thereby avoiding the necessity of a portion of the frame extending around the lamp at this point of juncture to hold the ends of the panes in place.
G is a door-frame hinged to one of the legs of the frame D, and is provided with any suitable lock, F, by means of which it is secured, when closed, against accidental opening. Upon the top of this frame D there is secured an overhanging dish-shaped metal cover, H, as a roof, with a central aperture, 0, said cover being surmounted by a metallic casing, I, surrounding such aperture, and having a door,
J, opening on the same side or in the same direction that the door G opens below it. This 0 chamber is open at top, and the. doorway opening into such chamber has no cross-bar at top. When in place and in operation, the hood usually found over the electric-arc lights is immediately over the top of this chamber.
By the use of this lamp the danger of breaking the globes is avoided, facilities for changing the carbons and regulating the lamp are offered by means of the doors, and, when the doors are closed and the lamp in operation, 100 wind, sand, snow, rain, and dirt are excluded. Should by accident a pane of glass be broken,
it can be very readily replaced with but little expense. I
Practical experience has demonstrated that, while this lamp is fully as economical in first cost as that of the globe, its liability to accidental breakage is far less.
The chamber I upon the top of the lampframe and its roof is designed to inclose the feed mechanism of the lamp; and it will read ily be seen that this can be reached and adjustedwithout difficulty through the open door.
I am aware of the Patents Nos. 288,151 and 306,998, and make no claim to the constructions shown therein. Nor do I claim, broadly, a light'protector, for I am aware that such is old.
I deem it important that the frame be provided with a socket, A, to fit on the support of the lower carbon, whereby the protector is readily and easily placed in position and no fastening means are required; hence it is re movableaby simply disengaging the socket and lower carbon-support. I
I also attach importance to my overhanging metal roof with its chamber I, as said roof prevents the rain, snow, &c., trickling down over the glass, and the chamber forms aprotection for the feeding mechanism, the top ofsaid chamber being covered by the hood-usually found over the electric-arc light, thus fur nishing a close, durable protector at a minimum of cost.
- adapted to inclose the'feed mechanism of the lamp, substantially as set forth.
3. An electric-arc-lamp protector consisting of a metallic frame holding panels ofglass, v
in an upper and lower section, a door leading into the upper of said sections, an overhanging disk-shaped metallic roof surmounted by an open-top chamber having a door leading thereinto, and a socket-snpport below the bottom proper, theparts being constructed and operating substantially as and for the purposes described.
GEORGE JEFFERY.
