LILLIAN HALE SPIVEY, OF ARNIM, TEXAS.
ADJUSTABLE LIGHT SHADE AND REFLECTOR.Specification of Letters Patent.
Patented Mar. 7, 1.911.
Application filed June 6, 1910. Serial No. 565,316.
To all whom it may concern:
Be it known that I, LILLIA IIALE SrIvEY,
a citizen of the United States, residing at
Arnim, in the county of Wharton and State
5 of Texas, have invented certain new and
useful Improvements in Adjustable Light
Shades and Reflectors, of which the follow-
ing is a specification.
My invention relates to new and useful
10 improvements in adjustable light shade and
reflector.
The object of the invention resides in the
provision of a shade and a support there-
for so provided with joints that the shade
15 may be given any desired angle of reflec-
tion, relative to the light, and its relative
distance from the light may be regulated.
Another object resides in the provision of
a clamp member where by the shade may
20 be securely attached to and readily removed
from its support.
With the above and other objects in view
my invention has particular relation to cer-
tain novel features of construction and op-
25 ration an example of which is given in this
specification and illustrated in the accom-
panying drawings, wherein
Figure 1, is a side elevation of the com-
plete device. Fig. 2, is a side elevation of
30 the clamp member and the universal joint
carried thereby. Fig. 3, is a plan view of
the socket nemnber of the joint and the
clamp member carrying the same. Fig. 4,
is a plan view of the washer designed to
35 line the joint socket. Fig. 5, represents the
ball member of the joint.
Referring now more particularly to the
drawings, wherein like numerals of refer-
ence designate similar parts in each of the
40 figures, the numeral 1, refers to a light
shade which is supported by rods 2, and 3,
hingedly secured together by an elbow joint
4. The supporting rod 3, is secured to its
support in the manner presently to be de-
45 scribed. This rod is designed to extend
through the opening 5, in the ball 6, as
shown in Fig. 1. This ball is provided with
a projecting rod 7, which extends through
an elongated slot 8, in the socket member 9,
50 and is outwardly threaded to receive the
thumb screw 10, by means of which the ball
is secured in its socket.
The numeral 11, refers to a washer con-
caved so as to conform to the socket 9, and
55 designed to be interposed between said
socket and ball 6. This washer is providedwith an elongated slot 12, designed to reg-
ister with slot 8, and receive the rod 7, and
its rim projects beyond the socket member
9, as shown in Fig. 2, and rests against the 60
rod 3, and holds said socket member from
contact with said rod.
The numeral 13, designates a laterally ex-
tending arcuate clamp member which is in-
tegral with the socket member 9, and to 65
which the member 14, similarly shaped is
hingedly secured as shown in Fig. 2. The
free end of member 14, carries a rod 15,
hingedly secured thereto, which is designed
to extend between the bifurcated extensions 70
16, of member 13, and is outwardly threaded
to receive a thumib screw 17, which may be
screwed down against the extensions 16, and
the members 13, and 14, thus secured around
the supporting arm of the support. The 75
concaved sides of these members are lined
with a suitable packing material 18, which
insures a firm grip of the clamp members
around their supporting arm and prevents
the wear of said arm. When it is desired 80
to elevate or lower the shade on the support-
ing arm the thumb screw 17, may be loos-
ened and the desired movement effected and
when it is desired to entirely remove the
shade the screw 17, may be loosened suffi- 85
ciently to permit rod 17, to pass entirely
from between the extensions 16, and the at-
tachment be removed.
It is obvious that the peculiar construc-
tion of the universal joint formed by the 90
union of a ball 6, and socket 9, will pro-
vide a joint freely movable, as the socket is
held from contact and friction with rod 3,
by reason of washer 11 and as the ball is al-
lowed a limited rocking movement in its 95
socket by reason of the elongated slots 8,
and 12, in which the rod 7, is permitted to
move.
A shade and reflector constructed in ac-
cordance with the foregoing specification 100
and the drawings accompanying the same
will be found to be capable of a ready ad-
justment, and will be easily attached to or
removed from the support on which it is to
be secured. 105
What I claim is:-
1. A device of the character described in-
cluding a shade support and a device for
securing the same to a stationary body, said
securing means being composed of a socket 110
member and a laterally extending clamp
member carried thereby, a spherical body985,852.
