SIGN FOR ELECTRIC LAMPS.

SPECIFICATION forming part of Letters'Patent No. 486,324, dated November 15, 1892. Application filed ilune 21, 1892. Serial No. 437,466. (No model.) i

To all whom it may concern.-

Be it known that I, EDWIN W. CLAY, of Louisville, in the county of Jefferson and State of'Kentucky, have invented a new and Improved Sign for Electric Lamps, of which the following is a full, clear, and exact description.

My invention relates to improvements in signs such as are adapted to be secured to lamps of various kinds and have the names upon them illuminated by the lamps; and the object of my invention is to producea simple and convenient sign which may be easily attached to an ordinary arc lamp, which may be adjusted and securely attached to the lampframe, which is held in such a way that the Words upon the sign may be distinctly seen either in the day-time or at night, and which is especially adapted for use upon streets, as it may be made to display to advantage the names of intersecting or crossing streets.

To this end my invention consists in certain featuresof construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of an arc lamp provided with my improved attachments. Fig. 2 is a sectional plan on the line 2 in Fig. 1. Fig. 3 .isa vertical section of the signframe and its supports on the l1ne3 3m Fig. 2. Fig. 4 is a perspective view of the frame as applied to the lamp-frame. Fig. is a broken enlarged sectional view showing in detail the supports of thesign-frame. Fig. 6 is a detail section on the line 6 6 in Fig, 5, showing the manner of making connection between the lamp-frame and the sign-supporting ring. Fig. 7 is a broken sectional view similar to that shown in Fig. 5, but illustrating a modified means of supporting the sign. Fig. 8 is a broken sectional plan of the supporting-ring and one of the clamps wh ch connect it with the sign-frame bolts. Fig. 9 is a detail view of an eyebolt used in the modified form shown in Fig. 7; and Fig. 10 is a detail view of a clamping-bolt, also used in the modified construction.

The arc lamp 10 is of the usual kind and in Figs. 2 and 5.

flanges at their edges which embrace the braces.

usual frame with curved side pieces. 11, and to this frame is secured a ring 12, which encircles the frame and is held above the globe of the lamp. The ring 12 has on diametrimay be of any kind, the lamp having the; v I

cally-opposite sides U -shaped clamping-pieces 13, which are secured to the ring, and bolts.

ring is preferably split, as shown in Fig. 6, to J facilitate its easy application to the lamp. The inner endsof the bolts 14 project through braces 16 and into clamping-plates 17, which latter are firmly held to the side pieces 11 of the lamp-frame by clamps 18, as best shown The clamping-plates have braceslfi, and thus strengthen the clamps and The braces 16 extend across the ring 12 on opposite sides and serve to stiffen the ring. Extending outward and downward from four sides of the ring are rods 19, the

inner ends of which are bent upward and made to lie flatwise against the ring 12, as shown at 20, these ends being attached to the rings by means of clamping-straps 21, which embrace the rods and are firmly secured to the ring. The upper ends of the rods are also provided with nuts 22, which prevent them from dropping. The outer ends of the rods are firmly bolted to the sign-frame 23, which is preferably of rectangular shape, having open side panels 24, in which the letters of the sign are displayed, as shown in Fig. 1, and these panels may be covered with glass of any desired color and theletters of the sign are produced upon the glass. It will be understood that the shape of the frame may be changed, if desired, and a greater or less number of supporting-rods may be secured to it.

To facilitate the sliding of the frame 23 up and down on lamps which cannot be easily reached to be trimmed, the construction shown in Figs. 7, 9, and 10 is employed. Here the bolts When the sign is used at street-corners, it

is arranged so that two of its sides will be as nearly parallel as possiblewith'the intersecting streets, and the name of one street is produced on one side of the sign and the na me-ot other street on the second side of the sign.

It will be understood that a sign upon= the frame 23 will show' up prominently in the day-time even, and when the lamp is lighted at nightthe letterswill stand out very plainly",

and consequently the device serves-n-icel y as i an advertising medium.

Having thus described my invention, I claim as new and desireto secure by Letters Patentit 1. A sign for electric lamps, comprising a ring adapted to embrace the upper portion of a 1amp-frame,transversebraces arranged within and on opposite sides of the ring, clam-psto secure the braces to the lamp-frame, and a sign frame supported by rodsattached to the ring; the frame having paneled sides in which the letters-of the sign maybe arranged, substantially as described.

2. A sign for electric lamps, comprising a ring arranged to embrace the upper portion of the lamp-frame, an open-paneled frame suspended from the ring, clamping mechanism for attaching the ring to the lamp-frame,

and means for adjusting the ring vertically on the clamping mechanism, substantially as described.

The combination, with the lamp-frame, of upwardly extending bolts or supports clamped to the frame and arranged on opposite sides thereof, a ring adapted to embrace the lampframe and the supports, bolts clamped to the ring and having split heads to slide on the supports, fastening-screws to clamp the bolt-heads to thew supports, and a A sign-frame suspended from the ring, all substantially as described.

4:. The combination with the'Jamp-frame, of clamping-pieces fastened to the sidesofi the frame, outwardly extending eyebolts :se cured to the clamping-pieces, upwardly-extending bolts or supports secured in the eyebolts, outwardly-extending bolts having split heads which areheld torslide on thesupp'orts, fasteningrscrews for secu'ring'thesplit heads to the supports, a ring clamped to the outwardly-extending sliding bolts, and a signframe suspended from the ring,substantially as described.
