The object of this invention is to provide an apparatus for tapping syrup and
other viscous liquids, constructed in such a manner as to allow an exact quantity
of the liquid to be swiftly brought into a vessel or the like, the vent of the apparatus
to be safely shut as soon as the required amount of liquid 'has been drawn off
and to prevent the part of the liquid remaining in the discharge pipe from being
lost by dropping on the floor.

of
syrup
The invention consists chiefly in combining with the receptacle for the
pump so arranged that when the syrup or the like is to be drawn into the pump the
pump-cylinder or working-barrel is moved in its longitudinal direction from the
outlet of the receptacle so that the cylinder end is open for the syrup to enter
and, when the syrup is to be pumped out, the cylinder will move back until it
is in communication with the discharge-pipe through which the syrup enters the
vessel into which is to be tapped. By this arrangement there will be no valve for
the syrup to enter through into the pump cylinder and hence no unnecessary
clogging. The invention further consists in the construction and arrangements
of parts herein after set forth.
The invention is illustrated in the accompanying drawing, in which Fig. 1
shows the apparatus partly in elevation and partly in vertical section, Fig. 2
shows a cross section of the same, and Fig. 3 shows the apparatus from below.
The apparatus consists in a receptacle a or the like for keeping the syrup, into
which receptacle a barrel or pump-cylinder is inserted in such a manner that
it can be moved in its longitudinal direction, said pump-cylinder being open below
and provided with a tightly fitting piston e secured to the lower. end of a graduated
rod d, whose upper end is provided with a suitable handle. The lower part of the
pump-cylinder, which is slightly conical on the outside, is loosely inserted into a
ring a at the bottom of the receptacle. In order to guide the pump-cylinder a plate
or disk a having a round hole for the barrel may be attached to the walls of the.
receptacle above the said.ring, and a socket a further attached to the cover of

the receptacle, said socket being provided with a collar a screwed into the upper
part of the socket. Thus an annular space is formed between the pump-cylinder
and the lower part of the socket 3. In this annular space a flange b', which is
attached to the pump-cylinder moves up and down according as the pump-cylinder
is raised or lowered. On account of the aforesaid it will seen that the downward
movement of the pump-cylinder is limited by the bottom of the receptacle and
the upward movement is limited by the annular flange b stopping against the
lower edge of the collar a. In order to prevent violent pushes, the upper surface
of the flange b¹ may be provided with a packing as illustrated in the drawing
At the top of the pump-cylinder 6 there is a cap 12 inserted into the cylinder and
provided with a hole through which the pump rod passes. The lid a serves to
close the receptacle after filling.
pro-
Under the bottom of the receptacle a mechanism for opening and shutting
the vent or outlet may be provided. This mechanism may consist of an arm f
one end of which may be turned about a bolt e, the other end of the arm being
widened and provided with a hole enclosing the discharge pipe h, which is fastened
in a moveable slide-valve g. The free end of the arm f moves in a horizontal
slot in the prolonged wall beneath the bottom of the receptacle. The slide-valve g
glides against a metal plate k provided with an opening i continued by an
opening in the bottom of the receptacle inside the ring a¹. The flanges
jecting from the plate k serve to guide the said slide-valve and hold it in position.
The slide-valve is pressed against the plate k by means of forked plate-springs 1,
so as to make a tight joint between the slide-valve and the plate, the former con-
tinually grinding against the latter. By moving the free end of the arm towards
one or the other of its extreme position a corresponding movement of the slide-
valve g and the pipe or tube h connected to the former is effected. When the
slide-valve has the position shown in Fig. 2 the opening i communicating with
the interior of the receptacle or the pump-cylinder is closed but when the slide g
is brought in its opposite extreme position the mouth of the pipe h arrives straight
below the said opening i, so that the syrup contained in the pump-cylinder may
be pressed out into the vessel into which it is to be tapped. The pipe may be
lengthened by means of a loose pipe m if necessary.
The arm may further be provided with a sliding-block n, adapted to carry
a cup by means of a curved wire or the like. When the apparatus is not in use,'
this cup may be put right below the discharge-pipe in order to receive the syrup
remaining in the said pipe, when the apparatus is to be used the cup is brought
to the side.
The apparatus may be provided with suitable fastening devices, so that it may
be attached to a wall or the like.
The described apparatus works in the following manner. The cup being brought
to the side, the vessel to be filled is put under the pipe h or its extensions m and
the slide-valve g is opened, so that the vessel communicates with the pump cylin-
der 6 or the receptacle a. The pumping is then performed in the usual manner
by moving the pump-rod up and down. In lifting the rod the pump-cylinder
follows on account of the friction between the piston and the cylinder, until the
flange stops against the lower edge of the collar a and the pump-cylinder
stops in the position shown in Fig. 2. The piston c now rises in relation to the
barrel, while the syrup is sucked up in the part of the barrel beneath the piston.
When the rod is pressed down the barrel follows until its lower edge arrives in
the bottom of the receptacle whereby the ring a¹ makes a tight contact with the
outer side of the barrel so that the communication between the barrel and the
receptacle is closed. By the continued downward movement of the pump-rod
the piston c presses the syrup contained in the cylinder through the pipe h to
the vessel placed under the said pipe. By continually raising and pressing down
the pump-rod the process described is repeated. The quantity of syrup pumped
into the vessel can be read off at the graduated pump-rod.
The different parts of the apparatus may be modified in several ways without
!

page_text: departing from the spirit of the invention. For instance a barrel lying on the
side could be used, said barrel being alternately pressed against and removed
from a ring or the like attached to the wall of the receptacle at the same time as
the pump-rod sucks in or presses out the syrup. The chief thing is that the
pump-cylinder is put into a reciprocating motion in such a manner that the part
of the barrel outside the piston communicates with the receptacle when the piston
is withdrawn and with the discharge-pipe when the piston is pushed in.

COMELNIE SPECIFICATION.
Improvements in Apparatus for Drawing Off and Measuring Syrup
and the like.
I, ERIC HERMAN ERICSON, of Oscarshamn, Sweden, Mechanic, 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:-
The object of this invention is to provide an apparatus for tapping syrup and
other viscous liquids, constructed in such a manner as to allow an exact quantity
of the liquid to be swiftly brought into a vessel or the like, the vent of the apparatus
to be safely shut as soon as the required amount of liquid has been drawn off
and to prevent the part of the liquid remaining in the discharge pipe from being
lost by dropping on the floor.
The invention consists in the construction and combination of parts hereinafter
described and claimed.
Referring to the drawings filed with the provisional specification Fig. 1 shows
the apparatus partly in side elevation and partly in vertical section, Fig. 2
shows a cross section of the same, and Fig. 3 shows the apparatus from below.
The apparatus consists in a receptacle a or the like for keeping the syrup, into
which receptacle a barrel or pump-cylinder 6 is inserted in such a manner that
it can be moved in its longitudinal direction, said pump-cylinder being open below
and provided with a tightly fitting piston c secured to the lower end of a rod d, whose
upper end is provided with a suitable handle. The lower part of the pump-
cylinder, which is slightly conical on the outside, is loosely inserted into a ring a¹
at the bottom of the receptacle. In order to guide the pump-cylinder a plane or
disk a having a round hole for the barrel may be attached to the walls of the
receptacle above the said ring, and a socket a further attached to the cover of
the receptacle, said socket being provided with a collar a screwed into the upper
part of the socket. Thus an annular space is formed between the pump-cylinder
and the lower part of the socket a³. In this annular space a flange b', which is
attached to the pump-cylinder, moves up and down according as the pump-cylinder
is raised or lowered. On account of the aforesaid it will seen that the downward
movement of the pump-cylinder is limited by the bottom of the receptacle and
the upward movement is limited by the annular flange b stopping against the
lower edge of the collar a. In order to prevent violent pushes, the upper surface
of the flange b may be provided with a packing as illustrated in the drawing.
At the top of the pump-cylinder b there is a cap & inserted into the cylinder and
:

page_text: provided with a hole through which the pump rod passes. The lid of serves to
close the receptacle after filling.
Under the bottom of the receptacle mechanism for opening and shutting
the vent or outlet is provided. This mechanism consists of an arm f,
one end of which may be turned about a bolt e, the other end of the arm being
widened and provided with a hole enclosing the discharge pipe h, which is fastened
in a moveable slide-valve g. The free end of the armm f moves in a horizontal
slot in the prolonged wall beneath the bottom of the receptacle. The slide-valve g
glides against a metal plate k, provided with an opening i continued by an
opening in the bottom of the receptacle inside the ring a¹. The flanges pro-
jecting from the' plate serve to guide the said slide-valve and hold it in position.
The slide-valve g is pressed against the plate k by means of forked plate-springs 1,
so as to make a tight joint between the slide-valve and the plate, the former con-
tinually grinding against the latter. By moving the free end of the arm towards
one or the other of its extreme positions a corresponding movement of the slide-
valve and the pipe or tube connected to the former is effected. When the
slide-valve has the position shown in Fig. 2 the opening i communicating with
the interior of the receptacle or the pump-cylinder, is closed, but when the slide
is brought in its opposite extreme position the mouth of the pipe h arrives straight
below the said opening. i, so that the syrup contained in the pump cylinder may
be pressed out into the vessel into which it is to be tapped. The pipe h may be
lengthened by means of a loose pipe m if necessary.
The arm may be provided with a sliding-block n, adapted to carry
a cup by means of a curved wire or the like. When the apparatus is not in use,
this cup may be put right below the discharge-pipe in order to receive the syrup
remaining in the said pipe, when the apparatus is to be used the cup is brought
to the side.
The apparatus may be provided with suitable fastening devices, so that it may
be attached to a wall or the like.
The described apparatus works in the following manner.
The pumping is performed in the usual manner. In lifting the rod the pump-
cylinder follows on account of the friction between the piston and the cylinder,
until the flange 61 stops against the lower edge of the collar a and the pump-
cylinder stops in the position shown in Fig. 2. The piston e now rises in relation
to the barrel, while the syrup is sucked up in the part of the barrel beneath the
piston. The vessel to be filled is now put under the pipe or its extension and
the slide-valve is opened. When the rod is pressed down the barrel follows until
its lower edge arrives in the bottom of the receptacle whereby the ring a¹ makes
a tight contact with the outer side of the barrel, so that the communication between
the barrel and the receptacle is closed. By the continued downward movement
of the pump-rod the piston c presses the syrup contained in the cylinder through
the pipe h to the vessel placed under the said pipe. The said process may there-
upon be repeated. The quantity of syrup pumped into the vessel can be read
off at the pump rod, which for that purpose may be marked or graduated..
:
The different parts of the apparatus may be modified in several ways without
departing from the spirit of the invention. For instance a barrel lying on the
side could be used, said barrel being alternately pressed against and removed
from a ring or the like attached to the well of the receptacle at the same time as
the pump-rod sucks in or presses out the syrup.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what
I claim is;
1. In an apparatus for measuring and tapping syrup or other viscous liquids
the combination of, a receptacle, a pump; the working barrel of which is moveable
longitudinally to a certain extent, a slide-valve moveable in cuidos autoih

page_text: discharge opening in the receptacle and pressed against the same by springs,
substantially as and for the purpose set forth.
2. In an apparatus for measuring syrup or other viscous liquids the combination
of, a receptacle adapted to contain the material to be tapped, a pump working
barrel of which is open below and moveable longitudinally to a small extent and
guided in the cover and near the bottom, a ring around the discharge opening
in the bottom adapted to fit snugly around the lower end of said working-barrel
when it is in its lowest position, a slide-valve moveable in guides outside the dis-
charge opening and pressed against the receptacle by means of springs, substan-
tially as and for the purpose described.
3. In an apparatus for tapping syrup or other viscous liquids the combination
with the receiver for the liquid to be tapped, of a pump tightly moveable in the
cover of said receiver to a certain extent and by its lower end fitting snugly in a
ring around the discharge opening when said working barrel is in its lowest
position only, a slide-valve moveable in guides outside the said discharge opening
and pressed against the receptacle fastened by springs, and an arm fastened by
one end to the receptacle and by the other end engaging the said discharge valve or
a discharge pipe fastened to the same, substantially as described.
4. In an apparatus for tapping syrup or other viscous liquids the combination
with the receiver for the liquid to be tapped of, a pump the working-barrel of
which is open below and moveable longitudinally to a certain extent and guided
in the cover an near the bottom, a ring around the discharge opening in the bottom
of the receptacle adapted to fit snugly around the lower end of said working barrel
when it is in its lowermost position, a slide-valve moveable in guides outside the
said discharge opening and pressed against the receptacle by means of springs
