To all wkomit may co ncem Be it known that I, VVrLLLu'r H. Sr'nxcnn, a citizen of the United States. residing at New York. the county of New York and State of New York,-have invented certain new and useful Improvements in Illuminating Devices; and I do hereby declare the-following to be a full, clear, and exact description'pf the inventioh. such as will enable others'skilled .in the art to which it appertains to make and use the same. reference being had to the accompanying drawings. and to characters ofreference marked thereon. which form a part of this specification.

The present invention relates. generally, to improvements in illuminating devices; and, the invention refers. more particularly. to a novel construction of illuminatin c devices adapted to be used in connection with bank-screens or partitions. counters. cashiercages, and similar arrangements.

The present invention has for its principal object to provide an illuminating device comprising the combination of a cornice. light difiusing reflectors and lighting units, all being combined and arranged in such a manner. so that when placed in proper position upon a partition or screen, such for ex ample as are used in banks for separating the difi'erent departments, the light-rays will be properly directed and redirected so as to throw the maximum light-flux upon the area to be illuminated. such as the desks or counters usually forming a partof the partitions or screens used in banks. counting, houses, factory-oflices. and the like.

A further object of the present invention is to provide a. novel and simple construction of illuminating device which may be artistically or ornainentally combined with screens or partitions; and, which will give a proper distribution of, light in a desired area, but. which will shield or screen the direct light from the eye, and will cause." fur thermorc. a soft and evenly diffused-light u ontheivorking surface or surfaces, the direct-glare of the light being eliminated.

Other objects of the invention not at this time more particularly enumerated, will clearly Understoodirom the detailed description of the present-invention.

With the various objects of the present invention in view, the said invention con sists. primarily. in the novel construction of illuminating devices hereinafter set forth;

and furthermore, this invention consis'ts, in

'the'novel arrangements and combinations of the variousdevices and parts. as well as in The invention is clearly illustrated in the accompanying drawings. in which Figure 1 is a plan or birds-eye viewpf a portion of bank-partition or screen provided with the stall or cage-partitions and the counters or desks arranged therewith. the same being provided'with the novel illuminating devicesiconstructed according to and embodying the principles of the present in vention. Fig. 2 is a transverse vertical section of the devices and parts represented in said Fig. 1, said section being t-a'kenron line 22 in Figure 1, and the. said view being made on an enlarged scale. Fig. 3 ave tical cross-section taken on line in said Fig. 1, this View being also made-on. an anlarged scale. Fig. 4 is a transverse vertical section of the novel illuminating device connected with the main partition onscreen,

similar to that shown in Fig. 2,"but the said view being made upon a. much enlarged scale; and Fig. 5 is a large detail. vertical, cross-section of the novel illuminating de vice connected .-with the stall- :or cage-par titions, similar to that shOWn'inFi-gfil',

Similar characters, 01f reference are em-L ployed in all of the above described'viewsj'toindicate corre ponding parts.

Referring now to the said" drawings, the reference-character 1 indicates a mainpart'ition or screen, such ,forfexainple as is used in banks, co.unting. houses, factory-offices. stores and. the like and the reference-char acterQ' indicates the Stall-OK cage -partitions connectedfiherew-ith. extending transversely withrelation to the main partitions 'or screen =1,-'a.nd adapted'tom arate the various bank-departments, or ot ier. departments from each other, as will be clearly evident from an in action of said Fig. 1' of the drawings. onn'ected with said main partition orscreen 1, and said stall or cage-partitions, are the usual desks or counters 3, the

said main partitions or screen being further provided with the usual openings or windows 4 and the vwindow ledges 5.

The novel illuminating device connected with'the said main partition or screen 1 is of thegeneral configuration and construction hereinafter more fully set forth, and the with which such partitions'or screens are usually provided, and thus in itself providing a cornice for the said partition or screen. The said cornice-casing 6 as it may be termed, overhangs the inner side of the said main partition or screen 1, and the same is (provided on its under side with a longitu i nally extending opening, along one margin of which extends an inwardly projectingledge or flange 7. Arranged within the interior of said cornice-casing 6 is the shell of a reflector-shell, said shell extending in a longitudinal direction throughout the inner portion of the reflector.- Said reflector-shell comprises an upright wall or member 8 which is provided with an outwardly projecting trough-like member 9,

the said upright-wall or member 8 may be secured, in any suitable manner, to a suitable flange or rib 10 with which said cornice-casing may be provided.

Connected with the upper portion of said upright wall or member 8 is a series of reflector-supporting facets or faces 11, the

same extending across the upper interior part of said cornice casing 6, and being arranged atproper angles to support a suitable number of reflecting elements in a mannor to properly direct and reflect the light of one or more light units in desired directions. Connected with said reflector-supporting facets or faces 11 is anotherupright wall or member 12, the same being secured,

inany suitable manner, to some convenient gart of the walls of said cornice-casing 6. roperly disposed and connected with said reflector-supportin facets or faces 11 are suitably formed 0 annel-bars 13, the same serving to sup rt and retain upon said reflector-supporting facets or faces 11, suitable reflector-members or elements 14, 14, 14

and 14 the latter being preferably made of silvered glass of any! desirable form. Said I trough-like member 9, which provides a wiring conduit or trough, is adapted to receive-the walls '15 of a light or lamp-supporting member 16, to retain the latter in. its

proper position and to support lightin units in proper relation to said wiring-conduit or trough, and said reflector members. Said engaging the inner side of said lamp-sup porting member 16. The wires 21-of the lamps 19 extend throughthe said sockets or brackets 18 and penetrate within said wiring-trough, where the same are pro erly and electrically connected in circuit Wit the vmain line or feed-wires 22. The upright walls or members 8 and 12 are also provided with a pluralit of holes or openings 23 for the purposes 0 ventilation and for carrying away, from the interior of the said reflectorshell, the heat generated by the said lamps. In like manner, the said cornice-casing is also rovided with a plurality of holes or openings 24 in its upper-Wall, which provide an outlet 'for the heatwithin said reflectorshell and the cornice-casing wh'ic-h col lects from said lamps, thus keeping the interior of the various devices and parts cool, and consequently prolonging the life of "the lamps. Disposed along the lower marginal edge of said upright wall or member 8 is a suitably formedhinge element 25 to which is pivotally connected, by means of corresponding hinge-elements 26 and a pintle 27, a frame 28 designed to sup rt acrom the openin in the bottom of said cornice-casing 6 a light-diffusing and softening screen 29, the latter being preferably made of ground glass, or some similar and suitable material. he outer marginal edge 30 of the said frame 28 is provided with suitable latchmembers 31, said members 31 .being formed with manipulating knobs 32, and the said latch members being adapted to engage the inwardly projecting ledge or flange 7 of the cornice-casing 6 toretain said frame 28 and screen 29 in their operative positions.- Said frame 28 may be divided into suitable sections, of any desired lengths, so that the same maybe conveniently openedto give access to any part of the interior of said'cornice-casing 6, as will be clearly evident.

Referring to Figure-4 of the drawing, reflector element 14 receives rays from the light source 19 and reflects them over the entire area of th light diffusing screen 29,

with none of the rays wasted, as can be noted by an inspection of Figure 4 of the drawing Where has been illustrated the direction of the redirection of rays a and b drawn to impinge on the extreme portions of the said reflector element. The reflector element 14 distributes its light, received from the source 19, substantially over the entire area of the drawn in a similar manner. 'flector elements, 14" and 149, each distributes screen 29, as disclosed by the re s c and d The two reits rays over the major portion of the screen 29, toward the counter, as illustrated by the rays e, f, g and h.'.

As illustrated in Fig. 4, the reflector members are mounted eooentrically with relation to the light source.

As thus constructed and arranged, with relation to the said partition or screen 1, the novel illuminating device herein-above described not only provides an ornamental completion of said partition or screen 1, but also so disposes of the lighting units and reflecting members, that the best light-efficiency and light diffus on 'is produced,

' and the reflector-members 14 are disposed at such suitable angles so that a maximum lightflux is directed over the entire working surface of the desk or counter 3; and, furthermore, the high reflecting and concentrating power of the said reflector-members 14. 14, 14 and 14 permits the use of lamps of approximately low candle-power. Said lampseing spaced at proper and suitable intervals throughout the length of said cornicecasing 6, and their light being directed from the various reflector-points or sources, causes such a distribution of light as to enable the clerk to work in any position when writing either left-hand or right-hand, without producing annoying shadows. Furthermore, the use of said softening and diffusing screen 29 screens the direct light from the eyes of the clerk or clerks, and causes an even and soft diffusion 'of the light, without glare, upon the working surface of said desk or counter.

Usually in the construction of bankartitions or screens, what are termed stal or cage-partitions are provided for the purpose of se arating the various pubhc windows departments from each other. In such construction, the said stall or cageartitions 2 are also provided with the sai cornicecasings 6 which are arranged to join or abut the said cornice-casing 6 of the main .par-

titions or screen 1. substantially as illus'-' trated in Fig. 1 of the drawings. Said cornice-casing 6 in such case, however, is

so arranged as to overhang each side of the and its slightly modified interiorconstrum t'ion upon a stall or cageartition is clearly 5 of the accom-' illustrated in Figs. 3 an panyin drawings. In this construction, the re ector-shell is supported within the upper interior part of said cornice-casing 6, the said reflector-shell comprising a troughing. Extending from each side of said trough-like member 33 is a set of reflectorsupporting facets or faces 34, the free marginal edges' of which may be suitably'secured to the respective walls of the said cornice-casing 6. Properly disposed and connected with said reflector-supporting facets 0r faces 34 are channel-like bars 35, which serve to support and retain upon said reflector-supporting facetsor faces 34 suitable reflector-members or elements 36, the latter being preferably made of silvered glass of any desirable form, or other similar and suitable material. Said troughlike member 33 is adapted to receive the walls 37 of a light'or lamp-supporting member 38, to retain the latter in its proper position so as to support lighting-units in proper relation to said wiring-trough or conduit and the said reflector members. Said lamp-supporting member 38 is provided, at suitable intervals, preferably twelve inches apart, with holes or openings 39 adapted to receive the sockets or. brackets 40 of lamps 41, each socket or bracket 40 being provided with a marginal flange 42 for engaging the inner side of said lampsupporting member 38. The wires 43 of each lamp, 41 extend through said sockets or brackets 40 and penetrate within the said wiring-trough or conduit, where they are properly and electrically connected in cir cuit with the main line or feed wires 22, arranged within said wiring-trough or conduita Said reflector-shell is provided, adjacent to its marginal edges, with suitable openings 44 providing means for ventilating and carrying off the heat generated by said lamps, said heat finally escaping through the holes or openings 24 with which said. cornice-casing 6 is provided, substantially in the manner here-inabove described. Said cornice-casing 6 is also provided with a ivotally'connected frame 28. and a light-diffusing and softening screen 29, hereinbefore described, the same being connected, however, by means of a hinge element 45 with which one wall of the said cornice-casing .6 is provided. The said frame 28 is also provided with the latchmembers 31 and manipulating knobs 32, the former of which engages said ledge or flange 7 of said cornice-casing 6, in the manner herein-above set forth. I I

The stall or cage-partition 2 is provided with open or cut-away spaces 46 lying directly beneath the illuminating devices, so that the light may be directed and diffused upon the surface of the desk or counter, upon either side of the said stall or cage partition. The reflector-members 36 are arranged in such a manner, so that the maximum flux of light from the lamps 41 is ditition, whereby this arrangement of the de- 'vices and parts has all the efliciency and at tributes 'hereinabove mentioned.

It will 'thus be understood, that by means of the resent invention, I have produced a hover-construction of illuminating de vice peculiarly adapted for use with that class of partitions used in banks, countinghouses, factory-offices, stores and for all similar work and purposes, the same presenting a sightly concealment of the lighting unit or units, and at the same time locating theisame and controlling the light generated thereby, in such a manner, so as to gain a maximum efliciency of light-tone, diffusion, and distribution;

I am aware that changes may be made in the general arrangements and combinations of the various devices and parts, as

well as in the details of the construction of the same, as described in the accompanying specifications, and without departing from the scope of my present invention as defined in the claims appended hereto. Hence, I do not limit my present invention to the exact arranigements and combinations of the devices an parts, asset forth in .the foregoing specifications, nor doI confine myself to the exact details of the construction of the said parts, as illustrated in the accompanying drawings.
