ILLUMI'NATING DEVICE.

Specification of Letters Patent.

Patented July so, 1912.

Application filed Oct0be1' 5, 1911. Serial No. 652,963.

To all whom it may concern Be it known that I,J0HN.A. GARLSTEDT, a citizen of the United States, residing at Brooklyn borough, in the county of Kings 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 of the invent-ion, such as will onable 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 of reference marked thereon, which form a partof this specification.

The present invent-ion relates, generally, to improvements in illuminating devices; and the'invention relates, to a novel construction of illuminating device adapted particularly for use in illuminating show-cases, show-windows, countercases and similar places.

The invention has for its principal object to provide an illuminating device, for the purposes above set forth, which is of a very simple and neat construction, and easily applied. One of the principal features of said illuminating device being the combination with the running wiring trough and a plu- 1 rality of illuminating units of detachable reflector members of exceedingly simple construction, and very easily manipulated to attach or detach the same in or from their operative relation with said wiring trough and said illuminating units. nating devices as have usually been employed to illuminate showcases, windows, counters and the like, are usually secured in a corner or angle, and the reflector-members have usually been permanently aflixed in such connection. Owing of the devices, and the fixed character of the reflector members, it has been found to be an awkward matter to get at said reflector members to clean the reflecting surfaces thereof. It is therefore to overcome such difficulties that the present invention is con-' structed. In the construction embodying the principles-0f the present invention the.

reflector members may be quickly and easily detached from the fixed parts of the illuminating device, cleaned, and replaced without disturbing any part of the wiring trough, or without disconnecting or removinghthe illuminating units connected therewit more particularly,

:novel illuminating device,

Such illumi to such a location tening means.

. provided at Other objects of this invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the'same. VV 1th the various objects of this invention 1n view, thesame consists,'primarily, inthe novel illuminating device hereinafter set forth; and the invention consists, furthermore, in the novel arrangements and combinations of the various devices and parts, as

well as in thedetails of the construction of the same, all of which will be more fully described in the following specification, and then finally embodied in the clauses of the claims which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in whlch Figure 11s a transverse sectional vlew of 'the corner of a show-case or the like ed with the novel construction of, illuminating device made according to the equipp principles of the present invention. Fig. 2 is a detail longitudinal section of the same taken on line 22 in said Fig. 1. Fig. 3 is i a detail transverse section taken on line 3 3-3 in said Fig. 2. Fig. t is a bottom viewof said novel construction of illuminating devlce with .the lllum nating unlts removed therefrom. Fig. "Sis a detail perspective view illustrating the wiring trough of the with the detachable reflector-members and their retaining parts removed from their assembled relation therewith.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts. a

Referring now to the several figures of the drawings, the reference-character 1 indicates the corner molding of a show-case, orthe like, having the usual glass sides2. The reference-character 3 indicates the base-portion of a-running. wiring trough adapted to extend longitudinallyalong said corner molding 1, and adapted to be secured thereto by means of screws 41, or. any other suitable fas- Connected with said baseportion 3 of said 'wiring trough are the out wardly flaring side walls 5, the same being their outer marginal edges with a retaining bead 6. Fitted within said wiring trough is an illuminating unit supporting member 7 which extends longitudinally through -.said wiring trough, and transversely across the opening thereof, slightly above I the position of said retaining beads 6. The side-walls 8 of said supporting unit extend upwardly within said wiring trough parallel to its sideewalls 5, but spaced slightly away from said side-walls 5, so as to provide an intervening receiving space 9. Said supporting member 7 is secured in the above described relation to said wiring trough by means of a plurality of suitably disposed retaining members 10 which are soldered, or otherwise secured, within said wiring trough, and the free ends 11 of which pass downwardly and are bent around said supporting member 7 so as to hold the same in its proper position withrelation to said wiring trough. Said supporting member 7 is provided at suitable intervals, with holes or openings 12 through which pass the retaining sleeves 13 of lamp-sockets 1 1, said'retaining sleeves being crushed over, as at 15, to form means for retaining said lamp-sockets in their connection with said supporting member. The usual electric wiring 16 extends through said wiring trough and said supporting member, the same being connected at vals With said lamp-sockets 14.

The reference character 17 indicates the electric light bulbs, which form-the preferabletype of illuminating unit.

The reference-character 18 indicates a de-.

tachable reflector-member, a pair of the same being connected with said wiring trough at a point where each illuminating unit is located. Each reflector member 18 is provided at its top longitudinal edge with a tongue portion 19, below which is located. a retaining bead 20 adapted to correspond to and be engaged by one of said retaining beads 6. The lower marginal edges of said reflector-member 18 terminate in a tubular bead 21 the interior spaces 22 of which, at each end of the same, provide receiving sockets for the stud-portions 23 of locking bars 2 1, which are arranged to engage and extend between the respective opposite ends of each pair of said reflector-members 18.

The said reflector-members 18 are attached and retained in their operative connection with said wiring trough and its illuminating units in' the following manner :-The tongue portion 19 of each reflector member 18 is inserted in the receiving space 9 lying between the side walls 5 of said wiring trough and the side walls 7 of said illuminating unit connected therewith. lVhensaid tongue portions 19 are pushed home the retaining bead 20 of said reflector-member 18 is brought. into'contact wi h said retaining bead 6 of said side-wall 5 of the wiring trough. It will of course be understood that a pair of said reflector-members are thus arranged on opposite sides of each illuminating unit. When thus arranged the lower longitudinal edges of said respectively opposuitable inter-' illuminating units,

site reflector-members are pressed outwardly to firmly press the

respective retaining beads

6 and 20 into engagement with each other.

This outward pressure is maintained by bers 18 in contact with' said beads 6 of said wiring trough, prevent said reflector members from becoming accidentally displaced from their above described attachment to said wiring trough. By removing said locking bars and moving said reflector members slightly toward each other the same may be easily and quickly detached, as will be clearly evident from an inspection of the drawings.

I am aware that changes may be made in the various arrangements and combinations of the devices and parts, as well as in the details of the construction of the same, without departing from the scope of the present invention as described in the foregoing specification, nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawmgs.
