LIGHTING FIXTURE
Otto G. Hildebrand, Cleveland, Ohio, assignor to
Railley Corporation, a corporation of Ohio
Application October 26, 1936, Serial No. 107,538
1 Claim.
This invention relates to an electric lamp which
is so constructed that it is adapted to be hung
upon a wall or to rest upon a ?at surface such as
a table Or desk.
One of the objects of the invention is to pro~
vide a lamp which is so constructed that it may
be supported either upon a wall or upon a ?at
surface and which is provided with means where
by the upper end of the lamp may be swung upon
10 an axis to permit the lamp to be used either
as a wall lamp or a table lamp.
Another object of the invention is to provide
a lamp of the character described which consists
essentially of a base member from which extends
15 an arm which is disposed at an angle to the
base member and made up of a pair of sections
connected together by a joint whereby the lamp
may be used as a wall lamp or a table lamp with
a minimum adjustment of parts.
20
Another object of the invention is to provide
a lamp of the character described which con
sists of comparatively few parts which are well
(Cl. 285-1)
provided with a lug or projection l8 which en
gages the projection I? and serves to limit the
movement of the arm 8 in either direction. A
suitable electric cable 20 extends through the
arms as shown and connects with the lamp socket. 5
The lamp is adapted to be supported upon a
wall by means of a suitable hook it or to be
supported upon a ?at surface as shown in Fig.
2. The spherical casing l I, in addition to enclos
ing the joint between the two arms serves as 10
a convenient means for gripping the lamp and
moving it from one position to another. The arm
8 ?ts tightly within the sleeve 5 so that it is
frictionally held in the adjusted position. It will
be seen that the outer end of the arm 3 is dis- 15
posed at an angle of 45 degrees with respect to
the base member and that the outer arm 8 is
movable through an angle of 180 degrees so that
the lamp may be positioned in a vertical plane
whether it be hung upon a wall or supported upon 20
a flat surface.
The arms 3 and 8 are each bent
at the same angle so that the lamp will be prop
adapted for production at comparatively low cost.
erly positioned and stand in a vertical plane
Further and more limited objects of the in
vention will appear as the description proceeds
whether it be supported on a wall or in a hori
zontal position.
and by reference to the accompanying drawing
It will now be clear that I have provided a
in which Fig. 1 is a view in side elevation of the
lamp supported on a wall; Fig. 2 is a similar
view of the lamp supported on a ?at surface;
Fig. 3 is an enlarged sectional view through the
30 joint; Fig. 4 is a detail View of the adjacent end
of the arms showing the lugs for limiting the
movement of the arms; and Fig. 5 is a sectional
View on the line 5—5 of Fig. 3.
Referring now to the drawing, the lamp con
35 sists essentially of a base member l which is pro
vided with a somewhat spherical portion 2, from
which extends a tubular member 3 which is se
cured in place by a suitable clamping nut 4. Se
cured over the opposite end of the member 3 is
40 an exteriorly threaded sleeve 5 which is held in
place by a clamping nut 6 which engages an en
larged portion 1 provided on the tubular member
3. Fitting into the sleeve 5 is a second tubular
lamp which will accomplish the objects of the
F arm 8 which is held in place by means of a clamp
invention as hereinbefore stated.
It is of course
to be understood that the embodiment of the in
vention herein disclosed is merely illustrative and
is not to be considered in a limiting sense as vari~
ous changes may be made in the details of con
0
struction without departing from the spirit of
my invention. The invention is therefore lim
ited only in accordance with the scope of the 35
appended claim.
Having thus described my invention, what I
claim is:
In a lamp consisting of a base member adapted
to be supported upon a wall or to rest upon a flat
surface and having an inner arm extending out 40
wardly therefrom and an outer arm rotatably se
cured to said inner arm and extending at an angle
thereto, a joint between said arms including a
sleeve surrounding the adjacent ends of said
arms, a casing enclosing said joint and compris 45
ing a pair of separable sections carried by said
sleeve, means carried by said sleeve and engag
which is made up of two parts 12 and I3 which - ing said detachable sections for securing the same
telescopically engage each other and are held in place, cooperating means on the adjacent ends
50 in place by the clamping nuts 6 and 9. Se

of said arms for limiting the rotary movement
cured to the opposite end of the arm 8 is a lamp thereof with respect to each other, said arms hav

light bulb therein and which is adapted to sup

port a lamp shade 16. The end of the tubular position.

and the adjacent end of the tubular arm 8 is

provided on the arm 8. Enclosing the joint be
tween the arms 3 and 8 is a spherical casing II
