Application led necemberl, 1909.

To all whom it may concern Be it known that 1, LINDSLEY Sonnen/tons, a citizen of the United States, residing 1n Hasbrouck Heights, county of Bergen, and State of New Jersey, have invented new and useful Improvements in Electric llfixtures, of which the following is a 'descriptlon My invention pertains to that class of electric fixtures or lighting apparatus adapted to contain an electric lamp or bulb and direct the light therefrom ina desired manner and direction' and protect the lamp or bulb from injury when .it is desired to use the same in exposed places. I

My invention has for its particular object to provide a fixture which may be used in railway cars adapted to be secured to the window panel alongside one of the seats "or in case of' sleeping cars in the corner formed by the window panel and the usual berth partition.

A further object of my invention 1s to provide a fixture which will direct the light of alamp in such manner that it will not shine upon the occupant of the opposite seat where the seats are placed facing each other as in sleeping cars.

A further object is to provide a lamp of such form and construction that it may be fastened in place without necessitating cutting of thewoodwork-that is, of such construction that the entire parts of the lamp or xture shall be self-contained and adapt` ed to be fastened Hush against the usual woodwork.

y invention is directed particularly to that class of fixtures in which it is desired to use high enciency bulbs such as metallic lament bulbs and on this acount it is ad` vantageous that the bulb should always be held with the filaments in a vertical position and that the switch or key used for turning the lamp on and ed' should not subject the lamp to sudden shocks or vibrations which would tend to break the filaments.

ln the drawing Figure 1 represents an elevation of my improved fixture as designed-for use in a corner as, for example, a corner formed by the window panel and the berth partition of an ordinary sleeping car to which the same is shown applied. Fig. 2 is a vertical in a plane midway between the two walls forming the corner shown in Fig. 1. i

follows: lly first fasten section of my improved fixture Patented dan. 5, 1915. Serial No. 532,305.

In the drawing 1 represents the walls or partitions to which my Ifixture is applied.

2 represents a back casting or frame secured to the walls as by the screws 3. casting or back plate is provided /with an extension 4 adapted to receive and hold in place the switch 5 and has fitted thereto the front or removable portion 6 which carries the prismatic globe or bowl 'i'. The removable portion 6 is extension 8 having two small gibs or hooks 9 adapted to pass through the opening 10 in the member 2 and engage the member as plainly shown in Fig. 2 in such manner that the screw 11 when made up into the top of' the member 2 will hold the member 6 firml rlhe bowl 7 is passed through the opening in the flanged portion 12 of the member 6 and is provided with a flange enga mg the same as indicated. The bowl 7 is rmly held in place by a metallic ring 13 which is passed under a couple of pins, one of which is indicated at 14C and then caught at another point by the screw 15 carried by the lug or boss 16.

17 is a web member carried by the mem ber 2 and having attached thereto a spring clip 18 so shaped as to rmly grip the soclret 19 and attached to the member 17 as by screws 20. rlhe socket 19 thus firmly held between the jaws of the spring clamp 18 is adapted `to hold the bulb 21 in its proper position within the fixture.

22 v'represents a reflector adapted to direct the back rays of the lamp so that they will pass ina desired direction through the prismatic bowl 7. rlFhe reflector 22lis carried by the member 17 and attached thereto as by screws 23. v

24 represents a wire cleat carried by the member 17 and adapted to hold the wires 25 in place, the said wires being connected with any suitable source of current and with the lamp 21 through the switch 5.

26 represents apertures in the member 2 for the purpose of' properly Ventilating the xture.

'lo place my fixture in use l proceed as the back plate 2 in place upon the walls 1 as by 'means of the screws 3, the proper. wires havin been led to the roper location in the pane s. ll then connect 1the wires witli the switch` 5 and the soclretI and then press the socket in provided with'- a flange orplace between the jaws nof the spring clip 1S. I then insert the bulb 21 in the ordinary manner and thenV place the bowl 7 in the front piece 6 as shown in Fig. 2, then place the ring 13. under the pins 14 and put in the screw l5 and tighten the same so as to bring the roper pressure upon the flange of the bowl I then insert the hooks 9 into the opening 10 until they en gage the back of the member 2. vI then swing the' upper part of the piece 6 into nearly a vertical position and lift the same slightly toallow the screw 11 to clear the` member 2 until the said screw engages its threaded aperture in the member 2.` I then make up the screw 11 which presses the `member 6 into the position shown in Fig. 2 and holds the same firmly in place. If the wires 25 are connected to thei proper source of current manipulation of the switch 5 will then turn the light on or olf and a snap movement may be used in the switch without subjecting the filaments of the lamp 21 to any severe vibration owing largely to the flexible manner in which the lamp is held. If desired to remove the bulbl the screw 11 may be backed out and the front piece 6' swung away from the member 2 and lifted so that the members 9 will disengage the back member 2 and then the piece 6 removed. Then the bulb may readily be removed. or the socket taken from its spring clip 18 if desired to permit of any examination of wiring, etc.

In practice I prefer to make the bowl 7 of such prismatic character that the refraction of the same will tend to concentrate the light given by the bulb 21 into a conical shaped beam directed approximately 45 degrees below thejhorizontal and 45 degrees in the lateral direction from each of the corner walls 1. When so directed the light in use in one corner of a section of a sleeper will b useful to the occupant of the adjacent at and not annoying to the occupant of the seat opposite which is a great practical advantage.

From the foregoing it will be plain that I have produced a fixture which may be applied to the corner formedby the window panel and the berth plar'tition in the ordi# nary sleeping car wit out cutting away of the panel or artition to make clearance for portions o the fixture. Further. that I have produced a compact form of fixture' which will cause the rays of the bulb or lamp contained therein to be directed in such manner as to be practically more useful than the ordinary exposed lamp used for this purpose. Also that I have provided a fixture which may be readily opened and f may be readily re cleaned and in which the parts needing renewal or repair are easily accessible and laced and that my fixture has Aself-contain?. therein' a switch in such position and so mounted that it will not be heated to any appreciable extent by the heat given out by the lamp and will not in its operation subject the filaments of the bulb to severe vibration.

I do not wish in any way to limit myself to the exact details of construction shown in the accompanying drawing as it will be obvious that considerable changes may be made in the design of my fixture without departing from the scope of the invention which is as set forth in the following claims:

l. Anv electric fixture having, in combination, an angular back-plate of a form adapting it to be secured in a corner or angle, and formed at its lower end into a receptacle for a switch mechanism, and above said receptacle into a support for a lamp; a bowl-carrier partially closing the front of said plate; Aand means for supporting the bowl-carrier at the top of said back-plate, substantially as described.

2.
