ELECTRICAL ILLUMINATING DEVICE FOR SHOW-WlNDOWS.

SPECIFICATION formingpart of Letters Patent No. 753,134, dated February 23, 1904. Application filed May 6, 1903. Serial No. 155,905. (No inodel.)

To all whom it may concern:

Be itknown that I, JOHN H. Gonns'r, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Electrical Illuminating Devices for Show-Windows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in electrical illuminating devices for illuminat ing show-windows and like places; and the invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a fragmentary vertical section view of a show-window, showing the manner of applying my improved illuminating device to the window. Fig. 2 is a bottom plan view of the device. Fig. 3 is a side elevation of the lamp-support with the sockets of the lamps and wiring attached therecasing and extends from one end thereof to the other. Said support is attached at its side margins to brackets 72, Fig. 1, which are riveted to the side walls of the casing and are provided with inwardly-extending arms, to which said lamp-support is attached by means of screws 5 L Said lamp-support is perforated to receive lamp 'sockets O, which extend through the openings in the support and are clamped on said support. Said sockets are preferably of the type shown in my copending application for United States Letters Patent, filed on the 12th day of May, 1902, Serial No. 107,013. The socket illustrated consists of a tubular body, which is provided on one end with an enlargement c, constituting an inwardly-facing shoulder, and inside said shoul der with screw-threads adapted to receive a clamping-ring 0, between which and the inwardly-facing shoulder the lamp-support is confined,whereby the sockets are held securely in place. Preferably a yielding packing-ring c is interposed between the inwardly-facing shoulder and the lamp-support. are provided with the usual metallic conductto, the parts being removed from the casing.

Fig. 4: is atransverse section taken on line 1 1 ing bars or strips 0 0 to which the conductof Fig. 2. Fig. 5 is an axial section of an aping-wires O are attached by means of bindingproved form of socket used in said device. screws 0 in a familiar manner. One end wall As shown in said drawings, A designates the upper front corner of a show-window, and B designates as a whole my improved illuminating device in position therein. Said illuminating device consists, in general terms,'of an'elongated casing which is open at one side and provided with a remoi able lamp-support, which carries the electric-lamp sockets and wiring in such manner that the sockets, the lamps, and wiring are assembled on thesupport, and the assembled parts are capable of be ing removed and inserted into the casing as a unitary structure. The casing is preferably made of sheet metal and comprises two side walls B B a top wall B and end walls B Said top and side walls are preferably strength sued by means of straps b, overlying the same and attached thereto by rivets in the manner shown in Figs. 1 and i.

B designatesa lamp-support detachably secured within the casing and consisting of a of the casing is provided with apertures, as shown in Fig. 1, through which the conducting-wires are led into the casing. Preferably reflector lamps having enlarged flattened bulbs and provided with upper interior mirrored surfaces are employed, though any preferred form of lamp may be used.

One of the side walls of the casing is provided on its inner face below the lamp-support with a longitudinal mirror D, which extends from said lamp support to the outer or lower margin of said side wall. Said mirror or reflector is embraced at its margins by grooved metal strips d, which are attached to theinner faces of said wall B by soldering or other suitable means. When the illuminating device is used for a show-window in the The sockets manner shown in Fig. 1- that is to say, is 10- 5 sheet-metal plate, which transversely fills the open sides thereof directed obliquely 'down I wardly. In this use of the device but one of the side walls, the outer side wall, is provided with a reflector, and the other side wall and the top, as well as the end walls, are usually blackened or otherwise made non-reflecting. If the reflector be employed, for instance. at the top of the show-window, near the middle thereof, both sides, as well-as the ends, of the casing may be provided with reflecting-surfaces. One or both of the side walls will desirably be provided with apertures If to afford ventilation about the lamps. A convenient manner of supporting the reflector in place in the window is to provide the top of the reflector with upwardly-extending lugs E, constructed to be clamped, by means of set-screws e, to depending brackets F, attached to the ceiling of the show-window and extending downwardly therefrom. In this manner the reflector-casing as a whole may be made to assume various inclinations with respect to the vertical, whereby the reflected light may be thrown where desired.

It will be observed that the attachment of the lamp-support across the casing in the manner described constitutes, together with said support, the upper parts of the side walls of the casing and the top wall thereof, an inclo' sure for the upper ends of the lamp-sockets,

and the conducting-wires which are attached thereto, whereby the current-conducting parts are reliably isolated from surrounding objects, so that a short circuit occurring within the inclosure will not be disastrous or endanger surrounding inflammable articles. It will be also observed that the lamp-support sockets, the lamps, and the conducting-wires carried thereby may be removed from the casing or inserted thereinto as a unitary or assembled structure and without disturbing the position of the casing in the window or its attachment thereto. When such removal of the support and the parts carried thereby is desired, the conducting-wires C may be cutoutside the casing and the screws removed, after which the support and the parts carried thereby and supported thereon may be readily removed from the casing. The parts may likewise in their assembled position be inserted into and secured within the casing, and after they have been inserted thereinto the wires C, which have been previously passed out through the openings in the end wall of the casing, are attached to the leading-wires outside of the casing. This is an important advantage, for the reason that it saves the trouble of handling the casing, which when made of great length is of considerable weight, and also renders it unnecessary to disturb the adjustment of the reflector after such adjustment has once been fixed. When the casing is made of considerable length, the lamp-supports may be made in sections of less length than the casing and joined at their ends in a manner to constitute when assembled a continuous support.

The shape of the casing may be varied to suit the different locations in which it may be used and may be attached to the show-window by a variety of devices differingin detail from that herein shown. I do not, therefore, wish to be limited to the precise construction shown except as hereinafter made the subject of specific claims. K

It is to be understood that the terms top, side, and bottom are merely used herein for convenience of describing the structure as illustrated, but are not to be regarded as limiting or essential terms, so far as the general application of the device is concerned.
