LIGHT-REFLECTOR.

Specification of Letters Patent.

Patented Sept. 23,1913.

Application filed April 1, 1913. Serial No. 758,279.

To all whom it may concern:

Be it known that we, Omvnn STTXRAS and Fawn X. Gnassarxo, citizens of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Light-Re lleetors, of which the following is a full. clear, and exact description, such as will enable others skilled in the art to which it a.p1 ertain.s to make and use the same, reference being bad to the accompanying drawings, forming part of this specification, in which I Figure 1 is a side elevational View, partly broken away, of our improved reflector. Fig. 2 is an enlarged vertical cross sectional view.

This invention relates to a new and useful im ,.\rovement in reflectors for concealed electric lamps and is designed particularly for use in lighting banks, libraries, railway stations, public buildings, etc., where it is desired to have the light rays directed in a particular direction.

Our improved reflector may be secured to the molding near the ceiling of the room to be lighted and constitute part of the finish of the room, in which event, the comparh mentcontaining the concealed lamps could be continuous around the room or on the beams or partitions, or, shorter sections coinplete in themselves and containing our invention could be employed as a table or desk lamp the compartment containing the lamps being supported on a suitable standard.

In reflectors of this character, it has been diflicult heretofore to clean the reflecting surfaces within the compartments without removing the electric lamps and it is the object of our present invention to construct containing walls in such manner that they may be separated to be cleaned and at the same time enable the glass in the bottom of the cmnpartmentto be removed also for cleaning purposes.

in the drawing- 1 indicates a back wall which is designed to be secured to the molding of the room, or said back "all may be provided with a lug 2 to which is secur-d a supporting post or standard 3 shown in dotted lines in Fig. 2. v

l indicates a trough in which the wires 5 for supplying current to the lamps (3 arranged. These lamps are arranged in suit able sockets and if desired the lamps 6 may be operated by a pull-cord 7 which passes down through an opening in the glass bottom wall. The upper edge of the wall 1 is preferably folded forwardly and downwardly to form, as at S, a groove to receive an interlocking flange of the removable cover. Under this groove is arranged a sniporting angle 9 soldered or riveted to the back wall 1.

10 indicates a removable coveizhaving an;

upwardly extending flange 11 at its-rear edge which is designed to fit in the groove formed by the folded over flange 8. This cover may be of any shape desired dependng upon the number and angular arrangement of the reflecting surfaces 12 secured therein.

if desired, the cover may also have a finishing molding 13 as indicated in dotted linesin Fig.2. The cover in the accom panying drawing is shown as being curved with an inwardly extending llange lt on its lower edge which flange is designed to fit under the, angle strip 15 on whose horizontal flange the glass bottom wall 16 rests. This glass bottom wall may be provided with reflecting ribs or corrugations, or it may be frosted or clear, as desired. The other edge or this glass bottom wall rests upon an inturncd flange 1 extending from the back wall 1.

ll'here the reflector is to be: used in long lengths the lamp compartments are divided at intervals, say oi" twenty-tour inches, by partition walls 17 which s rve to support the angle 15 and also the ends ol the glass bottom wall 1 3. Where these partition walls are emploved, they are cut away for the passage of the wire trough -l. The (over 10 is also made in short lengths, where long sections are employed, each cover preferably terminating coincident with the partition walls.

in practice. it it is desired to c ean the reflecting surfaces inside of the lamp rompartments, the flange let is pulled out from under the angle 15, the cover 10 being sullieicntly flexible to permit this and where a molding is employed as a finish to the crver this can readilv be done bv grasping the molding. or it the reflector is ns'd as a de k on the cover for disengaging the flange 1-1. .l'hrn th flange H is dseng'agcd the cover can be raised until the flange 11 is withdrawn from its groove, whereupon the cover becomes detached and .may be cleaned-at any place desired. When the cover is removed, the glass bottom walls 16 may also be removed by lifting them out of their re spective compartments, the hole' sfor the passage of the pull-cords 7 being sufficiently large to permit the buttons on the ends of said pull-cords to pass therethrough.

If it is desired to clean the back walls, vthis can be done by removing the lamps.

In re-assembling the reflector, the glass bottom walls are first put in position, the pull-cords arranged in their openings and the covers placed in position, first by inserting the flange 11 in its groove, then swinging the cover downwardly and springing the flange 14 under the angle 15.

WVhat we claim is:

1. A' light reflector comprising a lamp compartment, one wallof which has a separable hinged connection to another wall of said compartment, said detachable hinged wall having reflecting surfaces on its inner face and being provided with a locking flange at its free edge which is designed to be sprung into position to lock the detachable wall in place.

2. A light reflector comprising a lamp containing a compartment, the back wall of Whichis provided with a groove along its upper edge, a detachable wall having a fiange'fittlng into said groove and forming a separable hinged connection, the opposite edge of said detachable wall being provided with a flange designed to be sprung into position to lock the detachable wall into 7 place.

3. A light reflector comprising a back 'wall having a wire trough secured thereto,

said back wall having an inwardly extending flange at its lower edge and a folded over portion at its upper edge, walls extending perpendicularly to said back wall for supporting an angle piece, a glass bottom plate resting upon the bottom flange of the back wall and on said. angle piece, and a cover having an edge flanged to engage under the folded over portion at the upper edge of the back wall, said cover having an inwardly extending flange at its opposite edge designed to be sprung under said glass support angle.

In testimony whereof we hereunto afflx our signatures in the presence of two wit nesses, this 29th dayof March, 1913.
