I, JOHN HENRY ROUSE, machinist of Malden, County of Middlesex, Massachusetts,
United States 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 stands or supports for lamps or other articles, and has for
its object to provide an adjustable supporting stem or standard by which the lamp or
other stand may be raised and lowered to adjust it to any desired height.
-
My invention consists essentially in an adjustable stand, of a guide rod, a
surrounding tube, a braided wire tube connected thereto and surrounding the
guide-rod, and a head or receptacle connected to the said tube, combined with a
compressing device for the said braided wire tube, whereby the latter may be
compressed and expanded whenever it is desired to slide the braided wire tube upon
the guide-rod, to permit the head or receptacle to be adjusted relatively to the
guide-rod.
Also in an adjustable stand, a guide-rod, a surrounding tube, a braided wire tube
connected thereto and surrounding the guide rod and a head or receptacle connected
to said tube, combined with a compressing device for the said braided wire tube, and
with a spring to normally keep the compressing device out of engagement with the
said braided wire tube, all substantially as will be described.
Fig. in sectional elevation shows a lamp or other stand made adjustable in
accordance with my invention, the lamp fount being removed.
Fig. 2 a section on line xx, fig. 1.
Fig. 3 a section on line ¹¹ fig. 1, the supporting base being ouitted, and
Fig. 4 a detail on an enlarged scale, showing the guide rod and braided wire tube
nd part of the tube or sleeve to support the lamp or other article, the latter tube
eing broken off.

page_text: The base or end A, composed of metal or other suitable material, and of any desired
or fanciful design, supports a guide-rod a herein shown as screwed into a threaded
socket in the said base or end.
The head or receptacle c, to receive or sustain the lamp or other thing to be
supported, is joined to a collar 2 preferably by a threaded projection on the head or
receptacle entering a threaded hole in the said collar.
The collar 2 is secured to the upper end of a head-carrying sliding tube b which
surrounds the guide-rod a, the lower end of said tube having a cap bored centrally
the said cap having connected to it one end of a clutch composed of a braided wire
.ube 63 the internal diameter of which in its normal condition is substantially the
same as, or a trifle smaller than the external diameter of the guide-rod a.
The upper end of the braided wire tube has a small collar which fits the guide-rod
loosely.
The tube and the paris sustained by it are of such weight as to normally stretch
the braided wire tube, which contracts it in diameter and causes the tube to firmly
grasp the guide rod and operate as a clutch to prevent the descent of the tube b and
the parts supported by it.
Compression of the braided tube in the direction of its length will however cause it
to expand and release the guide-rod, in which condition the tube b may be moved
freely upon the guide rod up or down.
The cap supports a spring which is a little longer than the braided wire
tube 3 the said spring being of sufficient strength to support the braided wire tube
compression device, herein shown as a sleeve a² surrounding the guide rod a and
having a foot a* the opposite end of the sleeve a' being connected with a cross-
head a² see figs. 1 and 2, bearing a collar a³ the said cross-head passing through slots
in the tube b, the said slots being of such length as to permit the sleeve a¹ (the
operator grasping the collar a³ in his hand) to be moved toward the cap far enough
to cause the foot a* to act upon the free end of and compress the braided wire tube in
the direction of its length, as stated to cause it to expand and release its hold upon
the said guide-rod.
The sleeve b is extended through a guide d' supported by a standard d of larger
diameter than the sleeve b.
The standard d which may be of any desired or ornamental design, is of larger
diameter than the sleeve b, and to steady the sleeve and prevent its swaying or
vibrating the cap b' is made to fit somewhat snugly the interior of the standard d,
the latter aiding to guide the tube in a right line without one part binding or
cramping in the other.
I have herein described my improved adjustable stand as applied in the main to a
lamp but I wish it to be understood that I do not limit my invention to only such
application, as it is evident that my invention can be employed to good advantage,
whenever an adjustable support or stand for other purposes is desired such for
instance as vases to contain flowers, music-stands, and other articles the position of
which it is desired to adjust or change.
By the term head or receptacle I intend to cover a device to receive some thing
upon or within it, which thing is to be supported by or upon the stand, as for instance
the head or receptacle might be a shelf.
Having now particulary described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is.
First. In an adjustable stand a guide-rod a surrounding tube a braided wire tube
connected thereto and surrounding the guide-rod and a head or receptacle connected
to the said tube combined with a compressing device for the said braided wire tube
whereby the latter may be compressed and expanded whenever it is desired to slide
the braided wire tube upon the guide rod to permit the head or receptacle to he
adjusted relatively to the guide rod, substantially as described.
Second. In an adjustable stand, a guide rod a surrounding tube a braided wire
tube connected thereto and surrounding the guide rod and a head or receptacle

page_text: connected to the said tube, a guide for said tube and a standard to support said guide
combined with a compressing device for the said braided wire tube whereby the
latter may be compressed and expanded whenever it is desired to slide the braided
wire tube upon the guide-rod to permit the head or receptacle to be adjusted relatively
to the guide rod substantially as described.
Third. In an adjustable stand, a guide rod, a surrounding tube, a braided wire tube
connected thereto and surrounding the guide rod and a head or receptacle connected
to said tube combined with a compressing device for the said braided wire and with a
spring to normally keep the compressing device out of engagement with the said
braided wire tube, as and for the purpose set forth.
