PROVISIONAL SPECIFICATION.
A Machine for Filling into Receptacles Measured Quantities of
Liquids or Semi-liquids.
We HENRY COOPER and JAMES ROBERTSON both of No. 7 Dacre Road
Plaistow in the County of Essex Engineers do hereby declare the nature of this
invention to be as follows:-
The object of our invention is to provide a machine whereby an operator can
measure, and fill into receptacles, liquids and semi-liquids.
A reservoir or tank made any convenient size or shape is provided with a number
of measures. The measures being adapted to hold a predetermined quantity of
liquid or semi-liquid, and each one having an opening through the bottom. At the
bottoms of the measures a valve is fitted, acting alternately as receiving and
delivery valve. The part of the machine on which the valve rests is provided with
openings or nozzles corresponding in number to the measures, and placed in position
so that the contents of the measures is allowed to flow out through the valve into
the receptacles. When the valve is closed over the openings or nozzles, the liquid
or semi-liquid is allowed to flow from the reservoir or tank, into the measures,
when the measures are filled with a desired quantity, the valve cuts off supply from
reservoir or tank, and allows the contents of the measures to flow through the
openings in the bottoms of the measures, and through the valve and openings or
nozzles under the valve into the receptacles below. The valve being manipulated
by levers, an indicator recording the quantity of liquid or semi-liquid contained in
the measures being placed in a convenient position. The machine to be made of
any suitable material or metal.
In operation, the reservoir or tank is filled with liquid or semi-liquid, the
receptacles being placed under the openings or nozzles on the underside of
the valve. The valve is then opened by the manipulation of a lever, perinitting the
measures to be filled with a desired quantity of liquid or semi-liquid from
the reservoir or tank, when the desired quantity in the measures is registered, a
lever is then manipulated which opens the valve thus permitting the contents of
the measures to flow into the receptacles.

We, HENRY COOPER, and JAMES ROBERTSON late of 7, Dacre Road, but
now of 11 Selwyn Road Plaistow, in the County of Essex, Engineers, 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 a machine or apparatus for filling receptacles with
predetermined quantities of liquids and semi-liquids and especially adapted for
filling pots with syrup, jam or the like.
In carrying out our invention we employ a reservoir or tank of any convenient
size or shape provided with a number of measuring vessels adapted to hold a
predetermined quantity of liquid and each having an opening through the bottom
for the ingress and egress of the liquid or semi-liquid. At the bottoms of the said
vessels a valve is fitted adapted to act alternately as a receiving and delivery valve.
The part of the machine on which the valve rests is provided with openings or
nozzles corresponding in number to the measuring vessels and in such a position
that the contents of the vessels can pass out through the valve into the receptacles.
When the valve is closed over the openings or nozzles, the liquid or semi-liquid is
allowed to pass from the reservoir or tauk into the measuring vessels and when the
latter are filled with the desired quantity, the valve cuts off the supply from the
reservoir or tank, and allows the contents of the measuring vessels to pass through
the openings in the bottoms of the vessels and through the valve and openings or
nozzles under the valve into receptacles below. The valve is advantageously
manipulated by a lever, a pointer indicating the position of the movable end of
each vessel corresponding with the quantity of liquid or semi-liquid contained in
each measuring vessel.
To enable our invention to be fully understood we will describe how it can be
carried into practice by reference to the accompanying drawings, in which :-
Figure 1 is a side elevation of a machine or apparatus constructed according to
our invention for filling receptacles with predetermined quantities of liquids and
semi-liquids :
Figures 2 and 3 are respectively a vertical transverse section and a longitudinal
transverse section of the same; and,
Figure 4 is a horizontal section on the line 4-4, Figure 3:
Figures 5 and 6 are plans illustrating different positions of the operating lever:
Figure 7 is a section on the line 7-7, Figure 1 drawn to an enlarged scale; and,
Figure 8 is a section on the line 8-8, Figure 7.
a is the reservoir or tank for holding the liquid or semi-liquid to be filled into
the receptacles such as jam jars, and b, b, b are the vessels for measuring the liquid
or semi-liquid. We have indicated three of such vessels, but any other number
may be employed.
c, c c are the openings at the bottoms of the vessels b for the ingress and egress
of the liquid or semi-liquid, and d, d, d are the nozzles for the discharge of the
same into receptacles e, e, e, the said nozzles being in alignment with the
openings c, c. f is the valve for opening communication between the vessels b, b
and the interior of the tank a and the discharge nozzles d, d alternately. The
said valve is advantageously arranged to slide and is constructed with transverse
openings g, g in communication with the interior of the tank a and with vertical
openings h, h alternating with the openings g, y, the latter also having openings i, i
at the top so that when coincident with the openings c, c, as shewn in Figures 2

page_text: The
and 3, the contents of the tank a can pass into the vessels b, b. When, however,
the valve is moved so that the openings h, h coincide with the openings c, c and
nozzles d, d the contents of the vessels b can pass into the receptacles e, e.
wear upon the faces of the valve f and surfaces in contact therewith we advau-
tageously take up by drawing down the vessels !>, by means of screws f¹,
screwed through bosses in the bottom of the tank a and connected to lugs on the
said vessels as shewn clearly in Figure 2.

In order that predetermined quantities of liquid or semi-liquid shall be
measured, we arrange for varying the capacity of the measuring vessels b, b.
For this purpose we advantageously form the said vessels with movable ends j, j
working piston-wise within the vessels which are cylindrical and, in order that
the liquid or semi-liquid shall meet with no resistance in its passage into the
vessels b, b due to any confined air, we arrange the ends j, j to be moved so
as always to be in contact with the liquid or semi-liquid. With semi-liquids
such as jam this arrangement also facilitates the passage of the jam into and
out of the vessels b, b.
k, kare counterweighted levers for operating the movable ends j, j through
the medium of rods k², k², a cross-head ³ (working in guides k₁, k*) and
rodsk, k, the said levers being connected to a shaft k. is the lever for
operating the valve f, the said lever being in the form of a hand-lever and
fulcrummed at to the lever k in such a manner that its plane of movement is
at right angles to that of the said lever k whereby it also serves to operate the
latter and consequently the movable ends j,j. The operation of the said movable
ends is obtained by a vertical movement of the lever whilst the valve fis operated
by a lateral movement of the same, the free end of the lever acting in one direction
upon a bracket m adapted to slide upon the shaft k and connected to the valve j
by a rod m' working in a guide m², the bracket and valve being operated in the
reverse direction by a spring n. The movable ends j, j of the vessels b, b are
limited in their movement in one direction by the bottoms of the said vessels and
in the other direction by an adjustable stop (shewn clearly in Figures 7 and 8)
against which the lever k strikes in its upward movement. This stop is formed
with a projection of fitting in the slot p of a quadrant and having a stud p²
whereby it can be clamped in any position in the slot p by means of a nut p³ so as
to limit the upward movement of the lever k and movable ends j, j to vary the
capacity of the vessels and consequently the quantity of liquid or semi-liquid
delivered at each reciprocation. q is a pointer on the lever k working over a
scale g and serving to indicate, when the lever k is in its highest position, the
quantity of liquid or semi-liquid which will be measured or

To ensure that the lever at the termination of each up and down movement
shall not be again moved until the valve f is operated, we advantageously provide
means for automatically locking the said lever in such positions, the unlocking
being effected by the movement of the lever when moving the valve f. For this
purpose we employ two spring catches r, s, the catch being pivotted in an
extension upon the stop o so as to engage the bottom edge of the lever k when in
its highest position, while the catch s is pivotted upon a bracket t arranged in such
a position that the said catch can engage with the end of the lever k when in its
lowest position. To disengage the catches r, s from the lever we provide
projections u, v on the lever 1, the projection u serving when the said fever is
moved towards the lever k to push back the catch while the projection vis
arranged in such a position that its edge w forces back the catch s when the lever l
is moved away from the lever k.
The operation of the apparatus is as follows. Assume the tank a to be
charged with the liquid or semi-liquid to be filled into the receptacles, the
receptacles in position beneath the nozzles d, d, the movable ends j, j and con-
sequently the levers k and in their lowest positions and the valve fin the position
shewn in Figure 1, the lever being in a position corresponding with that of the

page_text: valve, that is to say, with the handle farthest from the lever k. If now the levers k
and are raised, the ends j, j will also be raised and the liquid or semi-liquid will
pass through the openings g, i in the valve finto the vessels b, b. The lever k
then coming into contact with the stop o will be locked thereto by the catch r, as
indicated in Figure 7. To disengage the lever k from the said catch, the handle
portion of the lever I must be moved towards the lever k whereby the projection u
will press back the catch as herein before described and the valve f be moved and
bring the openings, in line with the openings c c and nozzles d, d. By moving
down the levers k,l the contents of the vessels b, will pass into the receptacles e, e,
the lever k when at its lowest point being locked by the catch s as indicated by
the dotted lines in Figure 1 and in plan at Figure 5. To disengage the said
lever from the said catch, the lever must be moved back to its former position
relatively with the lever k, as indicated in plan at Figure 6, whereby the pro-
jection will force back the catch as hereinbefore described, and the valve be
moved so as to bring the openings, again beneath the openings, c. By
removing the filled receptacles e, e and substituting empty ones the operation can
be repeated.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A. machine or apparatus for filling receptacles with predetermined quantities
of liquid or semi-liquid comprising a tank or reservoir having one or more

or vessels and allowing the said contents to be discharged and levers for moving
the movable ends of the measuring vessel or vessels and the valve, the said levers
being so arranged that one of them is locked at the ends of its movement, but is
adapted to be unlocked by the movement of the other lever, substantially as
described.
3. The manufacture and use of the machine or apparatus for filling receptacles
with predetermined quantities of liquid or semi-liquid herein before described and
