This invention relates to new and usefulim
provements in brackets.
» One object of the invention is to provide an
improved bracket which-is particularly adapted
5 for use in supporting the usual “Lumiline” lamp.
An important object of the invention is‘to pro
vide an improved bracket which is arranged to
be attached to the ordinary “Lumiline” lamp
without changing the structure of said lamp,
l O whereby the _lamp may be connected with the
ordinary electrical outlet terminal, the bracket
serving not only as a support but also' as an
electrical/connector, which eliminates the neces
sity of employing a separate specially constructed'
bracket for illuminating the lamp.
Another object of the invention is to provide
an improved bracket for a “Lumiline” lamp which
is so constructed that a plurality of "Lumiline”
lamps can be placed in longitudinal alignment
20 and electrically connected to a plurality of the
usual electric sign receptacles or outlet terminals,
the bracket being adjustable vso that the con
nection may be readily made, irrespective of' the
position or location of the receptacles.

A further object of the invention is to provide
an improved bracket for a “Lumiline” lamp,
which bracket is secured to the usual removable

showing a modified form of bracket, and
Figure 7 is a transverse, sectional view taken
through one of the caps arid showing ‘another4 f
way of securing the'bars to the caps.
` In the drawing,the numeral I0 designates an
ordinary “Lumiline” lamp such as is> manufac
tured and sold by the -Generall Electric Company.
'I'his'lamp is cylindrical, being tube-like, and is
made in standard Ylengths of 12 and 18__vinches. 10
Each end of the lamp has a metallic terminal Il
which is _formed with a central recess l2.
A ilanged insulating cap `I3 isadapted to lit
over each terminal and this cap is` provided with
an annular spring contact i4. . When the capis 15
placed over the terminal, the contact I4 fric
tionally engages Vthe wall of the recess |2S'With a " '
releasable snap-fastener eiîect/to hold the cap
on the end of the lamp, and also to make elec
trical contact with the terminal. A metallic‘ear 20
orlug VI5 of electrical conductivity'extends out
wardly from one side of each capand this lug
is preferably made integral Withthe contact I l.
All of thev above described parts are of standard
manufacture'and form no part ofthe present 25
invention.v ’I'hey have been described merelyfor
the sake of clarity.
It is the usual practice to provide with each
inserted between or removed from the caps with
“Lumiline” lamp, a specially cónstructed> base
(not shown). This base has spring clips which v30
have electrical lead wires >connected therewith,
A construction designed to carry out the. ln
vention will be hereinafter described, together
with other features of the invention.
The invention will be more readily understood
35 from a reading of the following specification and
-by reference to the accompanying drawing, in
which an example of the'invention is shown, and

not only expensive to manufacture a base vi'or 35

-In carrying out the invention, a Ybracket I6
which not only serves asa support for the lamp,
but also may be inserted in the usual electrical
attachment plug outlet, whereby the lamp may 45;-->
be connected with s'aid outlet, isk provided. 'I'he '
bracket includes a pair of ñat electrical conductor
bars l1. Each bar as shown has one end soldered, e
or otherwise suitably secured, to the inner side
of oneV of jthe metallic lugs >I5 provided on the 50'
respective caps i4. ’I'he bar extends parallel to
the lamp and has its opposite end‘bent outwardly
from the lamp` so as to form a prong I 8. As is
clearly shown in Figures 1 and 2, the bent meeting
ends of the pair of bars extend parallel to each 55
other, whereby the prongs formed thereby are
spaced from each other. The thickness of the
bars I8, as well as the spacing between the prongs
is such that said prongs may be inserted in the
usual pair of slots I9 of the female portion of
an electrical outlet attachment plug 20.
Since one end of each bar is connected with the
lug I5 of one of the caps ofthe lamp and the
opposite end is inserted in the electrical outlet
10 attachment plug 20, it is obvious that the elec
trical current is conducted to the terminals I I
of the lamp, whereby said lamp is illuminated
when the plug is placed in an electrical outlet
socket. The electrical conductor bars I1, which
15 form the bracket, are covered with a suitable
insulating material 2i such as rubber.
From the above, it will be seen that a cheap

In Figure 7, another method of securing the
bracket to the cap of each ¿lamp is shown._ In
this form, each bar I1 is hingedly secured by a
