ELECTRIC-LIGHT FIXTURE.

Application filed September 18, 1914.

To ZZ whom t may concern:

Be it known that LW'iLLiAM J. BOHAN, a

citizen of the United States, and resident of St. Paul, county of Ramsey, and State of ldinnesota, have invented certain new and useful Improvements in Electric-Light Fixtures, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to electric light fixtures, its object being to provide a fixture which can be employed in exposed situations without danger of loss of any of the parts by pilfering. It is well known that electric 'mentioned and also securing a rigid fixture especially adapted for use in situations where it is subjected to serious vibration.

ln the accompanying drawings-Figure 1 shows a side elevation, some of the parts being broken away, of a table lamp embodying the invention; Fig. 2 is a side elevation, partly in section, of a pendent lamp; andv Fig. 3 is a side elevation, partly in section, of a wall lamp.

There is shown in Fig. 1 a base or standard 10, adapted to rest upon a table, and having' a suitable nipple 11 for the insertion of electric wires 12. 'The upper end or stem of the standard 10 is socketed, and the walls of the socket are provided with an upwardly facing seat, here shown as formed of a plurality of shoulders 13, 14, this seat being adapted toreceive and support the base .l5 of anelectric bulb 16 and as a point of attachment therefor, such attachment being conveniently secured by the use of screws 17. Arms, as 1S, 19, as many in number as may be desired, extend outwardly and preferably upwardly from the upper end of the stem of the standard, and at their outer ends carry a dome-shaped re- 'flector 20. The standard, the shoulders 13,

14, the arms 18, 19, and the reflector 2O are all formed integral.

The constructions illustrated in Figs. 2 and 3 differ from that of Fig. 1 only in that they are provided with bases 21, 22, adapted for attachment to a-ceiling or wall, and the reflectors 23, 24, are reversed from the position shown inv Fig. 1 and are formed by extending and flaring outwardly the walls of the socketed end of the stems 25, 26, of the standards or bases.

The fixture may be made of any suitable material, either metal, plastic or vitreous.

ln order to secure the highest eliiciency of a reiiector it' is important that the bulb be located approximately at its focal point Various styles of bulbs are made which vary in length, and the lixture forming the subject of this application readily adapts itself to the use of any of these bulbs, as the shoulders 13, 14, may be made of sufficient height to accommodate the shortest forms and may be readily cut away to suitably locate the longer forms of bulbs. In Fig. 3 the' shoulders 13, 1&1, are shown as reduced in height for this purpose.

l.' claim as my invention-- 1. An electric fixture comprising a base, a reflector, and a socketed stem uniting the base andreiiector, such parts being formed integrally, the socket walls being provided with integral lshoulders constituting seats and points of attachment for an electric bulb. i

2. In an electric fixture comprising a shade having a tubular stem provided with an outwardly facing shoulder forming a` seat and point of attachinent for an electric bulb, such parts being integral.

3. An electric lamp fixture comprising, in combination, a stem having a seat for a lamp socket, a reflector for a lamp carried by such socket, and arms projecting frointhe stem and carrying the reflector, the stenti arms and reflector bein integral.
