EDWIN F. GUTH AND RAYMOND V. OWEN, OF ST. LOUIS, MISSOURI, ASSIGNORS 'TO LUMINOUS UNIT COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI.
LAMP HOLDER AND REFLECTOR.
Specification of Letters Patent.
Patented Feb. 22, 1916.
- To all whom it may concern:
Be it known that W6,,EDWIN F. GUTH and RAYMOND V. OWEN, citizens of the United States of America, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Lamp Holder and Reflector, ofwhich the following is such a full, clear, and exact description as will en; able anyone skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.
Our invention relates to a combined reflector and lamp supporting device, particularly suitable for street and factory service.
Its object is to secure a wellinsulated, ventilated and weather-proof construction comprising a minimum number of easily accessible parts.
In the accompanying drawings, which illustrate one embodiment of our invention, Figure 1 is a side view, partly in section and partly in elevation; Fig. 2 is a plan view of the upper end of the neck of the reflector; and Fig. 3 is a bottom plan view of the reflector supporting stirrup.
1 represents a shade or reflector of insuv latmg material, preferably VFW/GOES china.
The reflector is provided with a central ex tension or neck portion as shown, and, ex-
tending across the neck portion and integral therewith is a socket carrying bridge 2 upon which the metal socket 3 is supported. The external diameter of the socket is less than the interior diameter of the neck portion of the reflector and thus a ventilating passage is formed between the socket and reflector and through the openings 4 in the top thereof. L 1e exterior of the neck portion of the reflector is provided with an integral shoulder 5. The divided supporting stirrup Q, having the arms 7, is held in position around the neck of the reflector beneath the shoulder 5 by means of the screws 8. The stirrup 6 may, of course, be
otherwise supported than by the arms 7,
.these being shown merely as one suitable arrangement for this purpose. A cap 9 covers the top of the neck portion of the reflector and rests upon the stirrup 6. 1t
is held in position by lugs 10 on the arms 7, being capable of being sprung sufliciently to pass these lugs for application or removal. The diameter of the cap opening is greater by a bowl or shade-13, if desired. This shade is also supported from the reflector, as
shown.
The reflector and socket support being formed in one piece and of insulating material, the construction of the fixture is much simplified since a .single member serves as the necessary insulating portion of a lamp socket as well as a shade. This, in addition to the arrangement of the supporting 'stirrup cooperating with the integral shoulder of the reflector and itself carrying the protecting cap, forms-a complete fixture for the purposes described having very few parts.
We are aware of prior devices in which a lamp socket is positioned within thebell or neck portion of a reflector, but these con;
structions do not possess the advantageous" features of construction herein described. 4
Having fully described our invention,
what we clairnas new and CieSlIQ to secure by Letters-Patentof the United States is:
l. The combination of a reflector or shade of insulating material having a socket inclosing neck portion provided with a ventilating opening, and a metallic lamp socket within the neck portion and supported by the reflector, the cross-sectional area of said socket being less than that of the interior of the neck portion of the reflector..
2. The combination of a reflector having a hollow neck portion and an integral socket supporting bridge extending over the end thereof, and a metal lamp socket attached to said bridge, said socket having a smaller cross sectional area than the interior of the neck portion of the reflector.
3. The combination of a reflector or shade of insulating material having a neck portion provided with an integral socket supporting bridge extending over the end thereof and an integral exterior shoulder, a reflector gaging with said shoulder, and a cap covering the end of the neck portion and supported on the reflector supporting member.
5. The combination of a reflector or shade of insulating material having a neck portion provided With an integral exterior shoulder,
. a reflector supporting member engaging with said shoulder, and a cap covering the end of the neck portion and supported on the reflector supporting member, the opening of said cap being sufficiently larger than the neck portion of the reflector to provide an opening between said cap and neck por tioir.
6. The combination of a reflector or shade of insulating material having a neck portion provided with an integral exterior shonlder, a reflector supporting member engaging with said shoulder, a socket supporting bridge extending over the end of the neck portion but not inclosing the same, a metal lamp socket attached to said bridge and of smaller cross-sectional area than the interior of the neck portion, and a cap covering the end of the neck portion of the reflector.
In testimony whereof, We have. hereunto set our hands and afiixed our seals;
