CHECK VALVE AND APPARATUS

REGULATING THE FLOW OF LIQUIDS."
" IMPROVED

FOR
My Invention relates to a novel construction and arrangement of check valve
and apparatus in connection therewith for regulating the flow of liquids, such as
oil to the wicks of lamps, whether hanging, bracket, table, ship, railway, or any
other kind of lamp having one or more burners for burning mineral or vegetable
oils, also applicable to boilers or stoves where a regular and continuous flow of oil
is required for heating the same, and for regulating the supply of water to cisterns
in lieu of the ball cccks or other existing appliances for that purpose, and generally
to any arrangement of apparatus for providing a regular and continuous flow of
water, beer, or other liquids.
My Invention consists as applied to oil lamps of a specially constructed check
valve placed between the pipe leading from the oil reservoir and the outer portion
of the wick reservoir. This valve is formed with a hollow stem open at its lower

end, and perforated on its circumference near the valve seat.
slides in a tube or socket closed at its lower end, and perforated thereat on its
circumference.
To the upper side of the valve is fixed a cylindrical (or other) shaped cup or
float, made of metal, glass, or other suitable material, which partially occupies the
outer portion of the wick reservoir and into which dips a tube or pipe fixed to the
lamp and containing the wick or wicks of the burner. This tube or pipe is formed
at the bottom with a strainer.
The oil from the oil reservoir passes through the perforated tube or socket, and
entering the hollow valve stem at its lower end passes through it and through the
DG11

page_text: perforation therein into the outer portion of the wick reservoir in which it rises
and floats or lifts the cylindrical cup or float to its utmost limit, when the oil, still
continuing to rise, passes over the upper edge of the cup or float into the latter
until at a certain level therein, when the weight of the contained oil overcoming
the specific gravity due to the displacement of the cup or float in the surrounding
oil will cause the cup or float to fall in the outer portion of the wick reservoir, and
with it the hollow valve stem falls in the tube or socket and closes the perforation
in each, thereby stopping the flow of oil from the oil reservoir to the wicks.
As the oil is burnt at the latter the upward pressure caused by the displacement
of the cup or float becomes greater than the weight of the latter with its contained
oil, and the cup or float consequently rises and admits more oil through the valve
stem to the outer portion of the wick reservoir. By this means the oil in the cup
or float is maintained at a constant level, and the light preserves its maximum and
normal intensity in lieu of diminishing as the oil is consumed according to the
present system.
When used for bracket lamps this check valve and apparatus is combined with
a cock or tap which is fixed in the supply pipe at the bottom or other convenient
part of the oil reservoir, its plug being connected by a fixed stem or handle to the
fixed bracket above the reservoir in such a manner that on turning the lamp and
bracket against the wall, the shell or casing of the cock or tap turns on the fixed
plug, thereby closing the cock and preventing further passage of oil from the
reservoir to the clieck valve and regulator at the lamp. A similar arranged
may be applied-to-hanging-lamps-or-chandeliers, -the-stem-or-handle-of-the-cock
being attached to any convenient fixture. If desired, in lieu of the improved
arrangement of check and regulator above described, I may use the check valve
and float described and illustrated in my previous Letters Patent, dated 22nd April
1880, No. 1659, for any of the purposes herein specified.
In table lamps I substitute for the check valve above described a tap or cock fixed in
the supply pipe from the oil reservoir and its plug furnished with a lever or handle
the end of which carries the cup or float before described. A spiral spring is placed
between the latter and any fixed portion of the lamp below, its elasticity being
exactly determined to support at a given compression the weight of the cup or
float with a certain quantity of contained oil. As the oil is burnt at the wick or
wicks of the burners the spring raises the lightened cup or float and with it the
lever or handle of the cock, which is thereby opened and allows the oil to pass
from the oil reservoir through a pipe from the cock into the cup or float, a constant
level and continuous flow of oil being thus maintained in the latter.
For railway lamps I may use the check valve and float described in my said
former Letters Patent, a syphon pipe being placed between the wick reservoir and
the wick holders for further checking any excessive flow of oil to the wicks.
When applying my improved check valve and regulating apparatus to water
supply cisterns the cylindrical cup or fluat is open to the cistern and rises against
a cover or stop on the outer portion of its reservoir, the water being drawn off
for use by a bent pipe, one leg of which dips into the water contained in the cup
or float, and the other leg or service pipe furnished with cocks or taps in the usual 4
manger
Or if desired the arrangement described in my said former Letters Patent may
be used to water cisterns.

AUTOMATIC СПЕСК VALVE AND APPARATUS CONNECTED THEREWITH FOR
REGULATING THE FLOW OF LIQUIDS."
My Invention relates to a novel construction and arrangement of chock valve
and apparatus in connection therewith for regulating the flow of liquids, such as
oil, to the wicks of lamps, whether hanging, bracket, table, ship, railway, or any
other kind of lamp having one or more burners for burning mineral or vegetable
oils; also applicable to boilers or stoves where a regular and continuous flow of oil
is required for heating the same, and for regulating the supply of water to cisterns
in lieu of the ball cocks or other existing appliances for that purpose, and generally
to any arrangement of apparatus for providing a regular and continuous flow of
water, beer, or other liquids.
On the accompanying Sheet of Drawings, Figuro 1 represents a detached
sectional view of my improved check valve and regulating apparatus, and
Figures 2 to 4 various applications of the same, like letters of reference indicating
corresponding parts in the respective Figures.
My Invention consists as applied to oil lamps of a specially constructed check
valve A (Fig. 1) placed between the pipe B leading from the oil reservoir, and
the outer portion C of the wick reservoir D. This valve A is formed with a hollow
stem a, open at its lower end and perforated on its circumference near the valve
seat. The hollow stem a slides in a tube or socket E closed at its lower end, and
perforated therent on its circumference. To the upper side of the valve A is fixed
a cylindrical (or other) shaped cup or float F made of metal, glass, or other suitable
material, which partially occupies the outer portion C of the wick reservoir D, and
into which dips the wick reservoir D containing the wick or wicks of the burner,
and formed at the bottom with a strainer, as shewn. The oil from the oil reservoir
passes through the perforated tube or socket E and entering the hollow valve
stem a at its lower end passes through it and through the perforation therein into
the outer portion C of the wick reservoir D, in which it rises and floats or lifts the
cylindrical cup or float F to its utmost limit, when the oil, still continuing to rise,
passes over the upper edge of the cup or float F into the latter, until at a certain
level therein, when the weight of the contained oil overcoming the specific gravity
due to the displacement of the cup or float F in the surrounding oil will cause the
cup or float F to fall in the outer portion C of the wick reservoir D, and with it
the hollow valve stem a falls in the tube or socket E and closes the perforation in
each, thereby stopping the flow of oil from the oil reservoir to the wicks. As the
oil is burnt at the latter the upward pressure caused by the displacement of the cup
or float F becomes greater than the weight of the latter with its contained oil, and
the cup or float F consequently rises and admits more oil through the valve stem a
to the outer portion C of the wick reservoir D. By this means the oil in the cup
or float F is maintained at a constant level, and the light preserves its maximum
and normal intensity in lieu of diminishing as the oil is consumed according to the
present system.
In Figure 2, which shews the application of my Invention to bracket lamps, this
check valve and apparatus C is combined with a cock or tap G which is fixed in
the supply pipe B₁ at the bottom or other convenient part of the oil reservoir H,
its plug being connected by a fixed stem or handle I to the fixed wall bracket K
above the reservoir in such a manner that on turning the lamp and swinging
