PROVISIONAL SPECIFICATION.
Improved Apparatus for Advertizing Purposes.
JOHN ORME Scientific Apparatus Manufacturer No. 65 Barbican London E.C., do
hereby declare the nature of this invention to be as follows:-
My Invention consists in "Improved Apparatus for Advertizing Purposes" and is
constructed as follows:-Letters, Monograms, or any other devices suitable for
advertizing are formed of glass tubing, or an equivalent transparent substance,
combined with metal or other suitable substance. A closed reservoir preferably of
glass is formed above and below the tubular device both being connected thereto and
also by a separate tube of larger diameter than that used in making the device to each
other. Provision is also made in the upper reservoir for partially filling the same
with a coloured or plain liquid but so that an air space is left in the upper part of
both reservoirs. A tube drawn out to a fine point mounted in the lower reservoir,
and is so placed with respect to the tubular device as that the liquid flowing through
the larger tube from the upper reservoir can only pass in drops separated by globules
of air, obtained from the upper part of the lower reservoir into the device above it.
Upon placing the apparatus thus constructed in the upright position the coloured
liquid circulates rapidly in a series of drops separated by air spaces throughout the
letters, figures or other device formed as described, producing a very attractive effect.
By simply reversing the apparatus the liquid flows into the upper revervoir again and
upon restoring it to the original position the circulation again commences.
When made of larger size I prefer to mount the reservoirs which may be made of
any suitable material at a distance from the device; in such case I pivot the tube
connecting these reservoirs thereto to a two way cock, which is coupled up in any
suitable manner with one; or more than one device as may be convenient. Several
devices may also be connected to separate reservoirs containing different coloured
liquids, or different parts of the same tubular device may be so connected.

COMPLETE SPECIFICATION.
Improved Apparatus for Advertizing Purposes,
JOHN ORME, Scientific Apparatus Manufacturer No. 65 Barbican London E.C., 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:
My Invention consists in "Improved Apparatus for Advertizing Purposes" and is
constructed as follows:-Letters, Monograms, or any other devices suitable for
advertizing are formed of glass tubing or an equivalent transparent substance
combined with metal or other suitable substance. A closed reservoir preferably of
glass is formed above and below the tubular device both being connected thereto and
also by a separate tube of larger diameter than that used in making the device to each
other provision is also made in the upper reservoir for partially filling the same with
a coloured or plain liquid but so that an air space is left in the upper part of both
reservoirs. A tube drawn out to a fine point is mounted in the lower reservoir and is
so placed with respect to the tubular device as that the liquid flowing through the
larger tube from the upper reservoir can only pass in drops separated by globules of
air obtained from the upper part of the lower reservoir into the device above it.
Upon placing the apparatus thus constructed in the upright position the coloured
D

page_text: liquid circulates rapidly in a series of drops separated by air spaces throughout the
letters, figures or other device formed as described producing a very attractive effect.
By simply reversing the apparatus the liquid flows into the upper reservoir again and
upon restoring it to the original position the circulation again commences.
When made of larger size I prefer to mount the reservoirs which may be made of
any suitable material at a distance from the device, in such case I pivot the tube
connecting these reservoirs thereto to a two way cock which is coupled up in any
suitable manner with one or more than one device as may be convenient. Several
devices may also be connected to separate reservoirs containing different coloured
liquids, or different parts of the same tubular device may be so connected.
To enable my invention to be clearly understood reference is made to the annexed
drawings in which :-
Fig. 1, is a front elevation of the self contained apparatus.
Fig. 2, is a side elevation shewing advertizing device connected to the reservoirs by
a two way cock.
Fig. 3, is a front view of a transparent device constructed partly of metal.
Fig. 4, is a side view of the same.
Similar letters indicate similar parts in all the views:-
1, Figs. 1 and 2, is the upper closed reservoir and z, the lower, both of which are of
glass. 3, is the transparent advertizing device which I have shewn as forming letters,
these or any equivalent monogram or figure are made in glass tubing and joined to
the upper and lower reservoir. 4, is the connecting tube between the two reservoirs
and 5, is a glass tube of small size sealed into the base of the tube 4, within the lower
bulb 2, and drawn out at its upper part into a fino capillary tube at 6. The tube 5, is
so placed as that the point 6 shall impinge against the narrow neck of the tubular
device 3, sealed into the top of the lower reservoir 2, so that the liquid from the
connecting tube 4, passes in elongated drops interspersed by air bubbles into the
device 3, above it, the air being displaced froin the bulb 2, by the overflow of part of
the liquid from tube 5.
The operation of this part of my invention is as follows:-
The apparatus is first reversed, and the bulb 1, and connecting tube 4, filled with
plain water or spirit or a colour such as an aniline dye in solution through the corked
opening 7. The apparatus is then set upright as shewn in fig. 1, and the plain or
coloured liquid descending the connecting tube 4, ascends the capillary tube 5.
Owing to the inclined position of this tube with reference to the device above it a part
only of the liquid enters the device in drops more or less elongated and interspersed
with air bubbles obtained from the lower reservoir by the displacement caused by the
overflow;
the drops and air bubbles travelling rapidly upward to the upper reservoir 1.
The pressure of the column of liquid in tube 4, with the compression set up by the
overflow in the reservoir 2, and the bouyancy induced by the interspersed air bubbles
being sufficient to force a part of the liquid upward through the device to above its
original level in the reservoir 1. When the air in the lower reservoir 2, is displaced
by the overflowing liquid the apparatus is reversed and the reservoir 1, refilled. Upon
restoring the apparatus to the upright position circulation again commences.
When the construction of the transparent advertizing device will permit it may be
enclosed in a glazed case as shewn in fig. 2.
When the advertizing devices are of large size or when a series are connected
together I prefer to circulate the liquid through a two way cock; in such case the
reservoirs may be placed at any distance from the device or devices.
In the drawing the two way cock is shewn as mounted upon the back of the case;
it may however be mounted independently with the reservoirs, suitable flexible or
other connections being made with the device or devices. In fig. 2, 1 and 2 are the
reservoirs; 4, the connecting tube; 5, the tube having capillary point 6; 8, is the two
way cock; 9, the plug; the ports 10, 101, which are connected by tubing with the
reservoirs 1 and 2; 3, is the advertizing device formed of glass tubing and mounted
in a case 11. When the reservoirs and two way cock can be mounted behind the case
as shewn the device may be sealed to the cock but when the reservoirs and two way

page_text: cock are mounted at a distance it is convenient to join the glass or other tubing
connecting the device or devices with the cock by rubber tube connections 13, similar
means being employed for connecting together a series of devices. The operation of
this part of my invention is as follows.
The position of the reservoirs 1 and 2, is reversed by turning them round, the
plug 9, cf cock 8, acting as a pivot. Plain or coloured liquid is now poured into
reservoir 1, and tube 4, through the corked opening 7, and the reservoirs turned back
to the position shewn. The liquid now circulates in the upward direction shewn by
the arrows through the device or devices as the case may be.
In some cases it is more convenient to construct the reservoirs, connecting tube and
two way cock of metal care being taken that the fluid employed shall have no corrosive
effect thereon.
Figs. 3 and 4, shew the construction of transparent advertizing devices when formed
partly of metal and partly of glass or equivalent material.
I prefer in constructing such devices to cast stamp or punch the letters, monograms,
or equivalent in thin metal such as copper. In the drawing 14, is the metal device
ports 15, are cored from letter to letter, or from part to part as the case may be ; or
these ports may be drilled or channeled in any convenient manner so that the liquid
may flow freely through the device, the edges of the metallic device are flanged up as
shewn at 16, and a glass plate 17, cemented on as shewn; pipe connections 18, enable
devices constructed as now described to be connected to the reservoirs. The glass may
be replaced by mica, celluloid or equivalent transparent medium if desired. Several
devices constructed as described may be mounted up side by side and supplied by
distinct reservoirs containing liquids of different colours, or different parts of the same
devices may be so connected.
The letters or equivalent may also be formed of glass tubing mounted in a case or
otherwise and connected together by rubber tubing at the back-or any other suitable
form of tubing may replace the rubber.
I am aware that toys have been constructed in transparent tubing through which a
liquid interspersed by air bubbles is circulated; to such I lay no claim; my object
being to circulate a plain or coloured liquid through transparent devices specially
constructed for advertizing by the means and in the manner described..
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
°
1st. The application and use for advertizing purposes of letters, monograms, or
similar devices formed of glass tubing or glass or equivalent transparent substance
combined with metal through which a plain or coloured liquid interspersed with air
bubbles is circulated in an upward direction by means of hydrostatic and pneumatic
pressure the air being displaced from a reservoir beneath substantially as shewn and
described.
2nd. The combination in or with advertizing devices formed wholly or in part of
transparent tubes or equivalent through which plain or coloured liquid interspersed
with air bubbles is circulated in the manner described, of the two way cock for
formning a pivot for the closed reservoirs and otherwise circulating the plain or
coloured liquid through the device or devices substantially as set forth."
3rd. The particular construction and arrangement of devices for advertizing
described under figs. 3 and 4.
