sHowcAsE REFLECTOR.
Application filed August 12, 1925. Serial No. 49,753.
My invention relates to show-case reflectors, and the general object thereofV is to 1mprove and simplify the construction of the same in the manner hereinafter set forth.
5 A special object of my invention is to provide a show-case reflector having a conduit for electrical conductors formed `@integral therewith, as for example, by reversely bending the lower end of the side member of said reflector to form such conduit.
Another object of my invention is to provide means whereby the reflector may con veniently be held in position in the show case by means of a spring clip, such clip having a flange formed on the lower end of its vertical side member for receiving and enclosing the aforesaid conduit, and a recess formed in its downwardly-inclined end portion for receiving a bead extending longitudinally throughout the length of the cor-- responding portion of the reflector.
A' further object of my invention is to provide a polyangular lamp socket arranged toV be received by and snugly fit within the reflector, such socket having a channel covoperating with the upper surface ofthe aforesaid conduit.
With the aforesaid objects in view my invention comprises a trouglrshaped showcase reflector having a substantially-vertical side member terminating in a conduit for electrical conductors formed by bending the lower end of said side member backward on itself, and a substantially horizontal top member terminating in a down\v:udlyin clined side member provided with a bead co'- extensive with the length of said reflector.
My invention comprises also a resilient clip having a substantially-vertical side member and a subst-antially-horizontal top member, the former terminating in a liange for receiving the conduit and the latter in a bead extending beyond and adapted to snap over the downwardly inclinedside member of the reflector and containing a recess for receiving said longitudinally-extending bead. l
My invention comprises also a polyangular lamp socket shaped to fit said reiiector and provided'with a longitudinal channel for receiving the upper surface of said conduit.
My invention contemplates the use of refiector members such as white opal glass, vitrified metal, glass mirrors and the like, '55 although the interior surface thereof may be plated with nickel or other suitable metal and highly polished.
When removable reflectors are employed my invention contemplates the use of retain-v ing clips suitably shaped-to hold said reflectors in position and having their en'ds disposed, respectively, in the depression formed by the aforesaid longitudinal bead in the surface of the downwardly-inclined side 6.5 member of said reflector, and in the space between the vertical side member and the reversely-bent lower end thereof.
An illustrative embodiment of my invention is shown in the drawings which accom- '70 pany and form a part of this specification in which y Figure 1 is an under plan view of a showcase reflector embodying my invention; and
Figs. 2 and 3 are transverse sections taken 75 respectively on the line 2-2 and 3,-3 of Figi l.
In the particular drawings selected for more fully disclosing my invention l() represents the substantiallywertical side mernber of my improvedshow-case. reflector, said side member having its lower end bent back on itself to form the vconduit ll for the electrical conductors l2, 1Q, said conduit vbeing shown in the present instance as substantially-oblong in section', although obviously it may have any other suitable shape. The sub- Stantiallyhorizontal top portion 13 of the reflector terminates inl a downwfardly-inclined side memberld having a bead l5 90 form-ed in the surface thereof and extending longitudinally throughout its length. In the present instance the side and top members of the reflector are joined by the pory tion 16 shown in the drawings as angularly 95 related thereto, although it will be under- Stood of courseth'at the connecting member` 16 may have any suitable shape. 1 j
The reflector consisting as aforesaid of the several portions or members l0, lf3, i4 and 100 16, preferably is bent into shape from a single metallic sheet, the inner surface of which may be plated and highly polished in the cheaper grade or" reflector; but l prefer to employ removable reflector members such as glass mirrors and the lik-e. rlhe .said reflectors are shown at 17 and are held in position by clips 18, one end ot each ot which is bent outwardly as indicated at 19 and disposed within the recess tormed in the under surface ot the downwardly-inclined m-ember 141 by striking out the longitudinallynextending bead 15, while the other end 20 is arranged in the space between the reverselybent lower end of the side member 10 and the vertical portieri of said member.
It will be understood of course that said clips are formed or resilient material and are snapped into position after the reflector strips have been placed within the show-case reflector.
In Figs. 2 and 3 l show a convenient means for removably securing the reflector to the show case with which it is intended to be used, said means consisting in the present instance ot' a resilient clip having' a sul stantially-vertical side member 21 terminating` in an upturned flange 22 which receives and encloses the conduit 11, and a substantially-vertical top portion 23 terminating in a downwardly-inclined end portion 24C which is provided in its under side with a recess 25 tor receiving the bead 15 and terminates in a bead 26 extending beyond and adapted to snap over the downwardly-inclined side member 14 of the reflector.
One or more lamp sockets 27 are employed, and in the present instance each socket is polyangular, being shaped to lit the reflector, and for the purpose of more firmly retaining the socket in the reflector, the lower lefthand corner thereof is provided with a longitudinal channel 28 for receiving the ripper surface of the conduit 11, a screw 29 or other suitable securing means being employed to fasten said socket to the reflector.
Preferably a .strip ot mica 30, or other suitable insulator is interposed between the recessed portion 31 oit' the socket which contains the lamp terminals 32 and the reflector, and the upper wall of the conduit 11 which is opposite the recessed portion b1 otl the socket is cut away as indicated at 33 for the passage ot the conductors 12, 12 from the lamp terminals to said conduit.
