- To all whom it may concern.

Be itknown that I, LoUIs M. Ema ls, a citizen of the United States, and a resident.

of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Wall- Illuminating Structures, of which the fol lowing is a specification.

The invention relates to structures for illuminating walls generally, whether they be exterior or interior walls, .or sign-boards, etc., but particularly for illuminating exterior walls of buildings which are providedwith overhanging cornices.

The object is to provide a wall-illuminating structure for supporting electric lamp sockets and reflectors, constructed and arranged to facilitate installation and repair, and to prevent injury to persons by reason of breakage of glass reflectors.

The invention is illustrated in the accompanying drawings of which Fig. 1 is a face view of the structure, the plane of view being indicated by the line I-I, Fig. 2; Fig. 2 a transverse sectional view taken on the line II-II, Fig. 1, the structure being shown in the preferred position which it occupies for illuminating an exterior wall of the building; Fig. 3 a sectional view taken on the line IIIIII, Fig. 2; and Fig. 4 a detailed sectional view taken on the line IV-IV,

Fi 1. j

The illuminating structure provided according to this invention comprises a trough,

preferably formed of sheet metal, having its 0 en side lying in a plane inclined, prefera 1y downwardly, from the vertical and closed by a removable plate which is preferably formed of a plurality of separate segments each independently removable from the trough. To the back of the trough there is attached an electric conductor conduit, in which, or adjacent to which, there are a plurality of lamp sockets mounted on brackets removably attached to the trough. On the removable front plate of the trough there are mounted reflectors which project inward ly from the plate so that in case a reflector is broken the pieces of it will fall into the ltwer portion of the trough rather than out o it.

Having reference to the illustrative embodiment of the invention, the trough includes a back 1 and sides 2 and 3 which are preferably arranged with the back to form a front plate 5.' *This plate is preferably ErsuEn reentrant trough chamber. The outer edges of the sides may be bent first towards back 1 and then towards the center of the trough to form shelves 4 to receive the edges of a formed'ofa plurality of segments having overlapping ends, one end being turned outwardly and the other being provided with a stiflening corrugation 6, as shown in Fi 4:. Each of these plates may be attache to shelves 4 by means of a pair of screws 7. Each segmentof the plate forming the removable front of the trough is provided with an opening adjacent to which there are suitable clips which may take the form of bendable lugs 8 for holding a reflector 9, the outer edge of which bears upon the plate adjacent to its opening.

On the back 1 of the trough there is an electric conductor conduit 10 which may take the form shown in Fi 2. It, too, may be formed of sheet metal avin edges 11 bent outwardly and soldered, or 0t erwise secured to back 1 of the trough. Lamp sockets 12 are preferably arranged in conduit 10 and mounted on suitable brackets 13 removably attached to the back of the trough by means ofscrews 14. The lamp sockets are arranged to register with openings in the back of reflectors 9 so that incandescent electric lamps 15 may be placed in the sockets from the outside of the structure.

While the structure may be variously shaped for illuminating different walls, it is preferably shaped as shown in the drawin for illumlnating an exterior wall of a building. When so shaped it may be arranged in an overhanging cornice 17 of a buildin with the open side of the trough inclined %own wardly from the vertical 1n a position to illuminate an exterior wall 16, the cornice and wall being indicatedin dotted lines in Fig. 2.

In case a reflector 9 is broken, it being understood that these reflectors are usually formed of mirrored glass, the broken pieces of the reflector will fall in the lower portion of the reentrant trough chamber rather than on a pavement below where inju to pcdestrians might result In case 0 trouble with a socket or reflector, access to each may be readily had without disturbin the entire structure. If a reflector breaks a that it is necessary to do is to remove segment 5 on which it is mounted and substitute a new refi ctor. In case of trouble with a socket, all m that it is necessary to do is to. remove the front segment 5 and the'bra cket 13 to which.

the socket is attached. 1

It is a further characteristic of the invention that the reflectors are supported in such a manner that they are readily accessible for cleaning.

According to the provisions of the patent statute, I have described the principle and invention, together with the operation of in ii I consider to represent the structure whic 7 best embodiment of it. However, I desire to have it understood that, within the scope of: the appended claims, the invention maybe practiced by other forms of construction than that particularly illustrated and described. v 1 '7 I claim. as my invention:

,1. A wall-illuminating structure comprising atrou h having its open side lying in a plane inclined from the vertical and closed by a removable plate, an electric conductor v and closed by a removable plate, an electric conductor conduit attached to the back of the trough,and brackets removably attached to the back of'thetrough adjacent to said conduit, lamp sockets attached to said brackets, and reflectors supported by said front plate. 7

In testimony whereof, I sign my name.

LOUIS M. RIDDLE.
