Improvements in Apparatus for the Automatic and Uniform Supply
of Liquids.
I, ISAAC WILLIAMSON Owler Lane, Sheffield, County of York Steel Worker, 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 has for its object to construct an apparatus, vessel, or reservoir that
will supply its contents whether of oil, water, spirits or other liquid, automatically and
in quantity exactly corresponding with the amount of liquid withdrawn for use... It
is capable of supplying a continuous and equal demand, such for example as drops at
regular intervals for lubricating purposes; a continuous supply to a fountain, or to
one or more connected lamps, or the irregular demand of one or a series of water taps
in a lavatory or the like, the force or pressure remaining the same from the com-
mencement to the emptying of the reservoir.
And in order that my invention may be clearly understood I have annexed a sheet
of drawings illustrating the apparatus.
of
Fig. 1, is a sectional elevation of a simple form of apparatus, suitable for a variety
purposes.
Fig. 2, an elevation of an apparatus designed for lubricating machine tools and
the like.
In carrying out my invention as shown in Fig. 1 I construct a closed vessel or
reservoir A, of any suitable form and size to hold the liquid, having a supply
chamber B, underneath, to which is attached the conveying pipe C, which leads
to the lamp, tap, fountain, or other appliance for which the liquid is required.
An inlet pipe D for the admission of air to the chamber B, communicates with the
atmosphere at any convenient point, and also with the upper part of the said chamber,
and the outer end is prepared for and provided with a cork D¹, or other like means
for closing the opening when required.
A second air-pipe E, communicates with the upper portion of the reservoir A, and
terminates with the end projecting for some distance into the supply chamber B; the
end of the pipe controls the height of the liquid in the said chamber.
A small supply pipe F, opens from the bottom or thereabouts of the reservoir into
the chamber B, and is preferably but not necessarily curved upwards as shown.
The liquid is supplied to the reservoir, through an opening closed by the screw
cap G, and a tap H is fixed on the pipe C to adjust or regulate the quantity of
liquid, and to close the pipe when required, such as when filling the reservoir.
When filling the reservoir with liquid, the tap H is closed, and the air pipe D, is
also closed by its stopper, the confined air will thus prevent the chamber B, becoming
filled with the liquid; the inlet G is then closed, and the stopper removed from the
pipe D.
The tap H is now opened and the flow of the liquid regulated to the desired
amount whether it is to drop slowly, or run in a stream; when the liquid in the
chamber B has lowered so as to unseal the lower end of the pipe E, air will at once
pass into the space above the liquid in the reservoir A, and a corresponding quantity
of the liquid will pass through the pipe F, into the chamber B, thus raising the
liquid and again sealing the end of the pipe E, until the next withdrawal causes the
same action to be repeated.
The liquid in the chamber B, will thus be constantly renewed and its normal level
retained, also a constant pressure will be maintained in the pipe C, and at the outlet,
which is a great desideratum, in the case of lamps especially.
The above description illustrates the principle of my invention, but I wish it to
Prine fd

page_text: be understood that I do not bind myself to the precise details, or to the exact
arrangement of the pipes, as these may evidently be varied, without departing from
the spirit of the invention.
In Fig. 2, I have shown an arrangement of the apparatus for supplying a lubri-
cating liquid to the cutting tools of machinery, and for other like purposes; the
letters of reference before used will also designate similar parts in this figure. The
chamber B, is here shown to screw onto the underside of the reservoir so that it can
be readily removed for cleaning it out, and also for adjusting the position of the tap
and its nozzle.
It is usual to support these lubricators upon a bar or rod K, attached to the machine,
by passing it into a tube I, secured to the side of the reservoir, and to fix it by means
of a thumb screw J.
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 :-
1-An apparatus for automatically renewing and regulating the supply of liquids,
having a reservoir A, a supply chamber B, air tubes D, and E, supply tube F, and
exit tube C, arranged and acting together in combination for the purpose specified,;
and substantially as hereinbefore described and as illustrated in Fig. 1 of the drawings.
2-An apparatus for automatically and instantly renewing from a closed reservoir,
any quantity of liquid withdrawn from a supply chamber connected therewith, by the
automatic unsealing of an air tube, and the admission of air into the said reservoir,,
thus permitting a corresponding quantity of liquid to pass into the supply chamber,
substantially as herein before described and as illustrated.
3-A lubricating vessel constructed on the principle hereinbefore described, and as
claimed in claim 2, the chamber B being detachable, and the arrangement of parts:
as shown in Fig. 2 of the drawings.
