Speciflcation of Letters Patent.

Patented May 7, 1912.

To all whom it may concern:

Be it known that I, LINDSLEY SoHErMoEs, a citizen of the United States, residing in Hasbrouck Heights, county of Bergenfand State of New Jersey, have invented new and useful Improvements in Electric Fixtures, of which the following is a description.

My invention pertains to that class of electric fixtures, or lamps, adapted to contain an incandescent lamp or bulb and direct the light therefrom in a desired manner and direction, also to protect the lamp or bulb from any injury when situated in exposed places.

My invention has for its particular object to provide a fixture which maybe used in railway cars adapted to be secured to the panel alongside one of the seats and to throw its light upon a book or paper which may be held by the occupant of the seat so as to form a reading light.

A further object of my invention is to so direct the light that it will not shine on the occupant of the opposite seat where the occupants face each other as in sleeping cars.

A further object is to provide a lamp or fixture which will direct its light when mounted in a sleeping car as above mentioned in such manner that, when the berth is made down, the lightmay 'be used by the occupant of the berth for reading.

My invention is directed particularly to that class of fixtures in which it is desired to use high efiiciency bulbs such as the metallic filament bulbs; for example, tantalum or tungsten and on this account it is advantageous that the bulb shall always be held in a'vertical position and shall not be submitted to sudden shock or jarring such as is caused by the operation of turning 011' or on an ordinary key socket. Y

A further object of my invention is to provide means whereby standard and readily purchasable parts may be used and easily replaced when worn out.

Referring to the drawing Figure I repremy improved fixture. Fig. II shows a vertical section of the parts shown in elevation in Fig. I in a plane at right angles thereto and a section of the panel or wall to which the fixture may be fastened. Also the electric lamp or bulb and its socket in elevation. Fig. III shows a top plan of that portion of the fixture shown in Figs. I and II which suplobe and which may be removed 7 ports the from the xed portion which is attached to the panel or wall. Fig. IV shows a perspective view of that portion of the fixture which is secured to the wall or panel and the means whereby the lamp or bulb socket is carried therein and means whereby a portion of the lamps rays are directed.

In the drawing, particularly Figs. I and II, 1 represents the back plate which ma be fastened to the wall or panel as by the s ews 2. .This carries the front-plate 3 which may be retained in place as by the screw 4 and which is provided with a prismatic globe 5 adapted to direct the light in a desired direction as will hereinafter appear. 6 represents an electric switch carried upon the plate 1 and controlling the current to the lamp or bulb as will readily be seen in Fig. II m which 7 represents an incandescent lamp or bulb carried by the ordinary standard socket 8 and having the usual connection with the switch 6 and the lighting cir- I cuit as by means of the wires 9. The socket 8 is held in place by the spring-clip 10 which is held in place by the screws 11 engaging the yoke 12 forming part of the back-plate 1 as'is clearly shown in Fig. IV.. The yoke 12 is provided with an extension 13 carrying the reflector 14, a port-ion of which is cut away as indicated at 15. The globe 5 is held in place within the member 3 as by.

means of the flange 16 which engages the flange 17 on the globe, the two flanges being held together as by means of the.spun ring 18 which is inserted under two pins, one of which is shown at 19 and then caught under the head of the screw 20, engaging the boss 21 forming part of the member 3 in such manner that, when this screw is drawn up, the spun ring will force the globe 5 tightly into place and allow the same to be readily removed at any time by withdrawaf of the screw 20. The member 3 is provided, near the top, with two gibs 22 adapted when held in a certain position to engage the openings 23 in the plate 1 in such manner that, if they be insertedin the said openings and then the member 3 be slightly raised, the

.gibs 22 will engage the back of the plate 1 so as to firmly hold the member 3 at the top, then making up of the screw 4 into the back-plate as indicated at 24 will hold the member 3 firmly in place.

vThe way in which my lamp or fixture is assembled and made ready for use is as follows, starting with the back-plate and parts assembled as shown in Fig. IV: A socket, as indicated by 8 in Fig. II, is properly wired into the switch 6- and connected through said switch into the lighting circuit. The back-plate 1 may then be screwed in place upon the panel or wall as indicated in Fig. II. The bulb 7 may then be screwed into the socket 8 and the socket pressed into place between the jaws of the spring 10 where it will be firmly held in position. The globe 5 may then be placed 'in the opening through the flange 16 of the member 3 as shown in Fig. II. Then the spun ring 18 may be caught under the pins 19 and the screw 20 inserted in the boss 21' and drawn up on the ring l8-so as to hold the globe firmly in place. The member 3, with the globe so attached, may then have the members 22 inserted into the openings 23 and then, if the member 3 be raised sufficiently to bring the screw 4 in line wit-h'the threaded aperture 25, the gibs 22 will engage the back of the plate 1 above the slots 23 and if the screw 4 be then made up into the plate 1, the member 3 will be held firmly in place and the lamp will be completely assembled. Then manipulation of the switch as by means of the buttons 26 and 27 will govern the operation of the lamp in a wellknown manner. The reflector 14 will cause the rays emitted from the back of the fila ment to be returned through the lamp and pass outwardly together with the direct rays through the prismatic lobe 5, the prisms of which have their ang es so selected as to throw the light downwardly atan angle of, approximately, 45 degrees below the hori zontal and tend to parallelize the rays in such manner as to cause very slight divergence and in this way prevent the rays from striking the eyesof a person at any appreciable distance to the right or left of the center of the lamp as viewed in Fig. I.

It will be noted that when my lamp is assembled and fixed in its normal positioh upon a wall or panel a considerable portion thereof is contained in the recessport-ion 30- of the wall, making a lamp which is always in an operative position without projecting very far into the room or car which is a very valuable feature in lamps designed for lighting car berths. It will also be noticed that with the lamp in place as shown in Fig. II the same may be. readily ventilated by a current of air entering the aperture 28 and passing around the bulb 7 and other parts liable to become heated and leaving by aperture 29, thus the bulb 7 while entirely covered so as to be protected, is still so ventilated as to prevent any excess temperature.

I do not wish in any way to limit myself to the exact constructions shown in the drawing for it is obvious that considerable departure can be made in the construction of my improved fixture without departing from the spirit and scope of my invention which is as set forth in the following claims:
