Improvements in and connected with Apparatus for Measuring
Liquids.
I, ELI JAGGER, of Green Street, Werneth, in the County of Lancaster, Tin-
plate Worker, do hereby declare the nature of this invention to be as follows:
This invention relates to improvements in and connected with apparatus: for
measuring liquids and has for its object to provide means which will permit of
drawing off or extracting, in accurate and predetermined quantities, from, vessels of
any form, liquid requiring measuring for instance such as water, beer, wine, spirits,
milk, oil, and the like..
To this end my invention consists in the particular construction and application
to the said vessels of a piston pump the stroke of which may be either a fixed one
or altered at will in accordance with the quantity of liquid to be drawn off, or
extracted. The said pump consists of a barrel and an outlet pipe the two being
connected by means of an elbow piece fixed to the pump bottom. The said
elbow piece is formed with two ports one serving for the admittance of the
liquid into the pump barrel and the other for the transfer to the said outlet pipe.
In connection with the said ports are employed two valves of suitable type which
prevent the back flow of the liquid. The said piston has a rod guided in the barrel
end formed at its free end with a button, knob, or handle, or being hinged to a
lever suitably fulcrumed, by which the piston is actuated, a spring or weight may
be suitably employed to raise the piston to its normal position, after having been
depressed.
In order to regulate the stroke of the piston in accordance with the quantity of
liquid to be drawn or extracted I form on the barrel end a fixed stop or I employ
a sleeve or stop having externally a screw thread engaging in a thread formed in
the upper end of the pump barrel. The said sleeve or stop may be screwed up or
down so as to cause a suitable projection on the piston rod to abut against it and
thus limit the stroke of the piston as may be desired, a nut being employed upon
the said sleeve or stop to lock it in position.
In lieu of the stops described when using a lever to actuate the said piston its
descent may be regulated by means of a fixed or an adjustable stud or stop
employed in connection with the said lever.
The -pump described may be permanently fixed to the vessel or suitable fixings
may be provided to render the pump readily removable, or the pump may be used
in the vessel independent of any fixings whatever.

Improvements in and connected with Apparatus for Measuring.
Liquids.
I, ELI JAGGER, of Green Street, Werneth, in the County of Lancaster, Tin-
plate 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
y the following statement:
This invention relates to improvements in and connected with apparatus for
measuring liquids and has for its object to provide means which will permit of
drawing off or extracting in accurate and predetermined quantities from vessels of
any form, liquid requiring measuring for instance such as beer, water, wine, spirits,
milk, oil, and the like.
To this end my invention consists in the particular construction and application
to the said vessels of a piston pump the stroke of which may be either a fixed one
or altered at will in accordance with the quantity of liquid to be drawn off or
extracted.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a longitudinal section and partly an elevation of a pump constructed in
accordance with one form of my invention and shown applied to a vessel, Fig. 2 is
a plan thereof.
Fig. 3 a longitudinal section of a pump constructed in accordance with another
form of my invention shown detached from the vessel.
Fig. 4 is a longitudinal section and partly an elevation of the' pump showing a
inethod of altering the stroke of the piston.
Fig. 5 is a side view showing a modification of the upper portion of the pump
barrel..
In carrying out my invention and referring to the Figure 1, the said pump
consists of a barrel a having a flange a', a piston b and an outlet pipe c, a & b being
connected together by means of an elbow piece d soldered or otherwise, fixed to the
bottom of the pump barrel a. The elbow piece d is formed with two ports e & f,
as shown in section Fig. 3, e serving for the admittance of the liquid into the pump
barrel a and for the transfer to the outlet pipe c. In connection with the ports è
& fare employed two valves e¹ & f' of suitable type which prevent the back-flow
of the liquid, i.e. on the outstroke of the piston & the inlet valve e' is drawn off its
seat to admit the liquid into the pump barrel a and the outlet valve f' is drawn
against its seat so as to prevent the back-flow of the liquid in the outlet pipe c
whilst on the return of the piston 6 the valve e' is pressed onto its seat so as to cut
off communication with the liquid vessel and the valve f1 is lifted off its seat to
allow of the measured liquid entering the outlet pipe c. The piston 6 has a rod g
guided in the barrel end or cap h and formed at its free end with a button or knob i
by which the piston d is depressed. Upon the rod g is fixed near its upper end a
collar o and upon the extension a loosely a disc o'. Between the said collar and
disc is employed around the piston rod ga spring in compression which serves to
raise the piston to its normal position after having been depressed, the collar o
abuting against the cover h.
The lower end of the pump barrel a may be formed with a contracted
extension a having holes a' in its side surrounded by a well m formed in the bottom
of the vessel n which holes cause the barrel extension below the face of the piston b
to be filled with liquid quicker than would be the case if drawn in through the valve
passage e only.
In order to regulate the stroke of the piston 6 in accordance with the quantity of

page_text: liquid to be drawn or extracted, I render the piston b adjustable on its rod g by
furnishing the latter with a thread and lock nut p by means of which the piston is
timed to abut against the bottom of the barrel, so as to limit its stroke.
In lieu of altering the stroke of the piston as described I may form on the barrel
end or cap h, see Fig. 3, a sleeve or stop o³ having externally a screw thread and
rendered adjustable in a thread formed in the cap of the pump barrel, against
which sleeve or stop of a collar g' fixed on the piston rod g is timed to abut and
thus limit the stroke of the piston as may be desired, a nut p being employed upon
the sleeve or stop o' to lock it in position.
In lieu of rigidly securing the collar gl on the rod g it may be rendered adjust-
able thereon by means of a set screw and timed to abut against the cap h direct as
shown in Fig. 4, and the upper end of the piston rod g formed with a ring i¹.
which is
Means for varying the stroke of the piston 6 may be also arranged outside of the
pump barrel a, as shown in Fig. 5, in lieu of inside, by hinging to a leg formed on
the barrel flange a', a hand lover k and the latter to the piston rod
raised by a spring placed between the cover and a shoulder on the piston rod
and the lever k when depressed being arranged to abut against a stud p preferably
rendered adjustable in a boss formed on the barrel flange a' and locked in position
by means of a nut p.
In lieu of the spring 1, shown in Fig. 5, the lever k may be formed with a
weight as shown in dotted lines.
By means of the flange a¹ the pump described may be permanently fixed to or
temporarily suspended from the top of any kind of vessel containing liquid to be
extracted in certain quantities.
The spring is only employed inside the pump barrel when formed with a
contracted extension and the holes in the latter only when the piston is rendered
adjustable on its rod.
The form of pump shown in Figs. 1 & 2 is generally applicable for extracting
small quantities of liquid and the handle shown in Fig. 3 for long strokes, whilst
the lever shown in Fig. 5 is for short strokes of pistons.
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-
"In and connected with apparatus for measuring liquids."
1st. The general construction and combination of parts constituting my improve-
ments operating and applicable substantially as set forth.
