Improvements in Electrio Light Hangers or Supports.
I, HERBERT LUTHER HOLT, of No. 6 State Street, Ellaworth, in the County
of Hancock and State of Maine, U.S.A. Dentist, do hereby declare the nature of
this invention to be as follows:-
This invention relates to electric-light hangers; and has for its object to provide
an improved banger for carrying an ordinary electric lamp. The improved hanger
is so constructed that it not only entirely incloses and conceals the electric wires,
but also provides means whereby the electric lamp can be adjusted in a variety of
different positions, as for instance drawn down, pushed up out of the way, or moved
to the right or left-and will stay rigidly in such position until it is desired to move
the same into another position.
With these and other objects in view, which will readily appear as the nature of
the invention is botter understood, the same consists in the novol construction,
combination, and arrangement of parts heroinafter more fully described.
The invention comprises a circular supporting-plate that is designed to be
suitably secured to the ceiling of a room and is provided with a series of depending
supporting lugs, having inner supporting-shoulders which receive the upper annular
flange of an upper supporting-socket, one of the said lugs being removable, so as
to allow for the insertion of the flange within the same and its detachment
therefrom. The said supporting-socket is thus suspended from the depending lugs
of said ceiling-plate so that the same may freely turn therein and give to every
movement of the lower supporting devices, and said socket may be detached from
the ceiling-plate when the device is to be secured to a wall, if so desired.
Pivotally connected to opposite sides of the upper revoluble supporting-socket
are the opposite supporting-arms, fixedly connected to opposite sides of one of the
oscillating adjusting cup-disks, located off from or below the said upper supporting
socket. The said cup-disks are provided with inner overlapping flanges, the flange
of one disk working in the flange of the opposite disk, and vice versa. The said
disks are provided with the opposite openings, which receive the clamping and
binding-bolt, passing therethrough and clamping said disks sufficiently tight so as
to cause the same to remain in whatever position they may be placed. A suitable
elastic washer may be interposed between the head of said bolt and one of said
disks to take off the strain of said bolts upon said disks.
One of the cup-disks is provided with a top perforation, which receives the
electric cord or wire passing from the ceiling or wall through the upper supporting
Bocket, and the opposite of said disks is provided with a threaded perforation,
which receives the inner end of one of the telescoping tubes, which receive the
electric cord or wire, passing through said adjusting oup-disks. The said telescopio
tubes telescope one within the other and may be arranged in any number desired,
according to the length of the supporting-arm that may be necessary to be used.
The end of the telescopic tube or tubes sliding within the larger tube is split to
form a series of spring-tongues, which bite the larger tube, and therefore serve to
hold the telescopic tubes in any adjusted position, as will be evident; but it will of
course be understood that the tubes themselves may work sufficiently tight within
each other, no as to remain fixed in any adjusted position. To the lower, or at
least outermost of the telescopic tubes is secured a pair of adjusting-diska, similarly
constructed to the above mentioned cup-disks, but smaller than the latter inasmuch
as only the weight of the electric lamp is carried by said smaller disks.
The disk annosite to the one secured to the outer end of the tolescopic tubes is

page_text: provided with a threaded projecting tube, which receives the ordinary electric
socket, which carries the ordinary electric lamp. The electric cord or wire passes
through the adjusting cup-disks 'at each end of the telescopic tubes and through
said tubes, and is thus connected with and carried to the lamp-socket without being
exposed to view, while at the same time every possible adjustment of the lamp may
be had. Now it can be readily seen that-the revoluble supporting socket allows
the wholo supporting-arm to be turned in any direction that may be desired, while
by the use of the adjusting cup-disks the telescopic lamp arm may be set and turned
at any angle desired, and also the lamp itself, according to the needs of the user,
while at the same time the whole device may be lengthened or shortened at will.
When shortened, the electric cord or wire is forced back into the larger cup-disks
and is drawn out from the same when the light-arm is lengthened.
In order to prevent the entire withdrawal of the telescopic sections of tubes one
from the other, those receiving and accommodating other sections are provided
with flanged screw-caps at their lower ends, having bottom openings exactly
registering with the tube sliding therein and through which the spring tongues of
ench tube will not pass.

COMPLETE SPECIFICATION.
Improvements in Electric Light Hangers or Supports.
1, HERBERT LUTHER HOLT, of No. 6 State Strect, Ellsworth, in the County
of Hancock and State of Maine, United States of America, Dentist, do
hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
.
This invention relates to electric-light bangers; and has for its object to provide
an improved hanger for carrying an ordinary electric lamp.
The improved hangor is so constructed that it not only entirely incloses and conceals
the electric wires, but also provides means whereby the electric lamp can be adjusted
in a variety of different positions as for instance drawn down, pushed up out of the
way, or moved to tlie right or left and will stay rigidly in such position until it is
desired to move the same into another position.
With those and other objects in view, which will readily appear as the nature of
the invention is better understood, the same consists in the novel construction,
combination, and arrangement of parts hereinafter more fully described.
In the accompanying drawing
Figure 1 is a side elevation of my improved electric-light-arm hanger'suspended
from the ceiling of a room.
Figure 2 is a vertical soctional view of the same.
Figure 3 is a detail in perspective of the ceiling-clamping plate.
Figure 4 is a sectional view of a pair of the oscillating oup-discs in position for
assembling.
Figure 5 is a detail sectional view illustrating the sliding connection between
the adjusting-discs.
A represents a circular supporting-plato that is designed to be suitably secured
to the ceiling of a room and is provided with a series of depending supporting-
lugs B, having inner supporting-shoulders C, which receive the upper annular
flange D of the upper supporting-socket E, one of the said lugs B being
removable, as illustrated in Figure 3, so as to allow for the insertion of the
flange D within the same and its detachment therefrom. The said supporting-
socket E is thus suspended from the depending lugs of said ceiling-plate so that
•

page_text: the same may freely turn therein and give to every movement of the lower
supporting devices, and said socket may be detached from the ceiling-plate when
the device is to be secured to a wall, if so desired.
Pivotally connected to opposite sides of the upper revoluble supporting-socket E
are the opposite supporting-arms F, fixedly connected to opposite sides of one of
the oscillating adjusting cup-discs G, located off from or below the said upper
supporting socket E. The said cup-discs G are provided with inner overlapping
flanges H, the flange of one disc working in the flange of the opposite disc, and
vice versa. The said discs are provided with the opposite openinga I, which
receive the clamping and binding-bolt [', passing therethrough and clamping
said discs sufficiently tight so as to cause the same to remain in whatever
position they may be placed. A suitablo elastic washer J may be interposed
between the head of said bolt and one of said discs to take off the strain of said
bolts upon said discs.
One of the cup-discs G is provided with a top perforation 9, which receives
the electric cord or wire passing from the ceiling or wall through the
upper supporting socket E, and the opposite of said discs is provided with a
threaded perforation g', which receives the inner end of one of the telescoping
tubes H', which in turn receives the electric cord or wire 1", passing through said
adjusting cup-discs. The said telescopic tubes H' telescope one within the other
and may be arranged in any number desired, according to the length of the
supporting-arm that may be necessary to be used.
The end of the telescopio tube or tubes sliding within the larger tube is split
at M Figure 5 to form a series of spring-tongues, which bite the larger tube, and
thereforo serve to hold the telescopic Lubes in any adjusted position, as will be
evident; but it will of course be understood that the tubes themselves may work
sufficiently tight within each other, so as to remain fixed in any adjusted position.
To the lower, or at least outermost of the teloscopic tubes His secured a pair of
adjusting-discs G, similarly constructed to the above mentioned cup-discs, but
smaller than the latter innemuch as only the weight of the electric lamp is carried
by the said smaller discs.
The disc G' opposite to the one secured to the outer end of the telescopic tubes
is provided with a threaded projecting tube I, which receives the ordinary
electric socket J', which carries the electric lamp K. The electric cord or wire In
passes through the adjusting cup-discs at each end of the telescopic tubes and
through said tubes, and is thus connected with and carried to the lamp-socket
without being exposed to view, while at the same time every possible adjustment of
the lamp may be had.
Now it can be readily seen that the revoluble supporting socket E allows the
whole supporting-arm to be turned in any direction that may be desired, while by
the use of the adjusting cup-discs the telescopic lamp-arm may be set and turned at
any angle desired, and also the lamp itself, according to the needs of the user,
while at the same time the whole device may be lengthened or shortened at will.
When shortened, tho electric cord or wire is forced back into the larger cup-
discs G and is drawn out from the same when the light-arm is lengthened.
In order to prevent the entire withdrawal of the telescopic sectious of tubes one
from the other, those receiving and accommodating other sections are provided with
flanged screw-caps I at their lower ends, having bottom openings exactly
registering with the tube sliding theroin and through which the spring tongues of
Buch tube will not pass.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In an electric-light hanger, the combination of a revoluble socket, adjusting-
discs, one of which is divotally suspended from said socket, and telescopic tubes

page_text: Buclose the electric cords passing through said socket and adjusting-diso,
substantially as set forth.
2. In an electric-light hanger, the combination of a supporting-socket, adjusting-
discs, one of which is pivotally suspended from said socket and receiving and
accommodating the electric cord therefrom, and telescopic lamp-supporting tubes
connected with the other of said discs and receiving and inclosing the electric cords
passing therethrough, substantially as set forth.
3. In an electric-light hanger, the combination with a supporting-plate having a
series of depending shouldered lugs, of a revoluble flanged Bucket resting nud
working upon said shouldered lugs, adjusting-discs, one of which is pivotally
Buspended from said socket and receiving the electric cord, and telescopic lamp-
carrying tubes connected with the other of said discs and inclosing the electrio
cords passing therethrough, substantially as set forth.
4. In an electric-light hanger, the combination of a revolublo supporting-socket,
hollow adjusting-discs, one of which is pivotally suspended from said sooket and
receiving the electric cord therefrom, telescopic supporting-tubes one of which is
connected at one end to one of said hollow adjusting-discs and enclosing and
currying the electric cord, and similar hollow lamp-adjusting discs, one of which is
connected to the outer end of another of the telescopio tubes and supporting the
electric lamp, substantially as set forth.
5. In an electric-light hanger, the combination of a supporting-socket, hollow
cup-shaped discs having overlapping flanges, a clamping-bolt clamping said disca
adjustably together, supporting-links pivotally connected with said sooket and
fixedly to one of said discs, telescopic supporting-tubes connected with the other of
said adjustable discs socured to the outermost of said telescopic tubes and
adjustably carrying the lamp, the electric cord passing through said socket, the
opposite adjusting-discs, and intermediate telescopic tubes to the lamp, substantially
as set forth.
6. In an electric-light hanger, the combination of a supporting-socket, hollow
cup-shaped discs working adjacent to said socket and provided with overlapping
flanges, a clamping-bolt adjustably olamping said discs together, elastic washers
interposed between the head of said bolt and said discs, supporting-arms pivotally
connected with said socket and fixedly to one of said discs, telescopic supporting-
tubes, one of which is connected at one end to the other of said discs, and similar
hollow cup-shaped discs, one of which receives one end of one of said telescopio
tubes and adjustably carrying the lamp, the electric cord passing through said
Bocket and entirely inclosed by the opposite adjusting-discs and the intermediate
adjusting tubes, substantially as set forth.
