To all whom it may camera:

Fig. 2;

trough Be it known that I REUBEN B. BENJAMIN, a citizen of the Un ted States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Show-Case-lLight1ng Devices, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, form ing a part of this specification.

My invention relates to show case llghtlng devices.

One of the objects of my invention is to provide an improved device of this character which is made in sections and which can be quickly attached and detached to make a fixture of anylength desired. 7

In the drawings, in which I have shown one embodiment of my invention- Figure 1 is a section throu h a show case showing my improved lightlng device located therein;

Fig. 2 is a section of Fig. 1;

on the line 2-2 line 3 3 line 44 line 55 line 6-6 line 7-7 Fig. 3 is a section on the Fig. 2;

Fig. 4 is a section Fig. 3;

Fig. 5 is a section Fig. 2;

Fig. 6 is a section on the on the on the Fig. 7 is a section on the Fig. 1; and I Fig. 8 is a section on the line 8--8 Fi 1.

Fteferring now to the drawings in detail, the device as shown comprises a plurality of similar sections 10 electrically and mechanically connected together end to end and located in any suitable position within the show case. Each section 10 comprises a 11 within which the lamps are 10- cate reflector members 12 located within the trough 11, two receptacles 13 one at each end of the trough 11, electrical connectlons 14 for supplying current to the receptacles 13, two lamp sockets 15 one supported by and engaging each of the receptacles 13, and tubular lamps 16 and 17 lying in the trough 11 and inserted in the sockets 15.

The trough 11 comprises an elongated ceptacles 13 are secured. These caps are secured to the channel members 18 in any suitable manner as by rivets 21. For holding the electrical connections 14 in, their properof the channel members 18 to which the rechannel member 22 by means of an eyelet 24.

The receptacle 13 comprises base 25 secured to the cap 20 by means of eyelets 26, spring contacts 27 for engagement with corresponding contacts on the lamp socket 15, said contacts being located an insulating 1n recesses 28 in the insulating base, terminal plates 29 to which the electrical connections 14 are soldered, screws 30 for electrically and mechanically connecting the plates 29 with the binding plates 31, and lolIldlIlg" screws 32 for engagement with the 'leadingin wires. Only one of the insulating bases 25 of the entire fixture is provided with the binding screws 32. In the other bases the binding plates 31 serve as part of the mechanical and electrical connections between the sections 10 and forthis purpose connecting and conducting screws 33 are provided (Fig. 6) having a threaded end 33 and a reduced shank portion 33 which is provided so that it will not be necessary to thread the screw through the plate 31 through which it is first inserted for its entire length before it can engage the second plate 31.

The base 25 is provided with suitable channels 34 for the leadingin wires 35 and is suitably recessed at 36 to accommodate the connections- 14. The connections 14 comprise a pair of insulating conductors 37 the ends of which are secured to the lates 29 in any suitable manner as by solderlng at 38. The lamp socket 15 comprises an insulating base 39, shell and center contacts 40 and 41 supported by the base 39, eyelets 42 for securing the shell contact in place, contact blades 43 for contacts 27 of the receptacle, and screws 44 for connecting the shell and center contacts with the contact blades 43. The spring contacts 27 and associated parts are so constructed that they will receive the contact blades of the cap of a separable attachment lug if desired.- The fixture may be secured in the corner of a show case 45 by means of suitable clips 46. Itwill be seen that by the use of these sections 10, a lighting device of any desired length may be built up and that these sections may be very easily mechanically and electrically connected by simply inserting the screws 33, two for each section after which the sockets may be slipped in place in the receptacles 13.

The connections 14 are made permanently at the factory before shipping and the receptacles 13 are also permanently secured to the caps 20. When the fixture is completely set up and connected the circuit is from one of the leading in 35 to the binding wires plate 31 through the screw 30 to the plate 29, through one of the conductors 37 to the 37 from one of the plates 29 through the spring contact 27 engaging the plate 29, through the contact blade 43, screw 424: center, contact l1, 1am circuit, shell contact 40, screw 44, contact b ade 413, spring contact 27 to the other plate 29 and the other conductor 37. The spring contact plates 27 are so located with respect to the trough 11 that the lamp with its socket 15 may be swung ,outwardly from the trough 11 when it '1s de sired to remove the lamp and insert another. Having thus described my invention what I claim as new and desire to secure by Letbase, a conductor plate base adjacent ters Patent is 1.
