IN PUMPING APPARATUS FOR BEER AND OTHER LIQUIDS, ACTUATED BY STEAM,
WATER, OR AIR PRESSURE, APPLICABLE ALSO AS A WATER METER.”
A com-
munication from abroad by Schläpfer and Sonderegger, of Lausanne, Switzerland.
The Invention relates to improvements in such pumping apparatus in which
small power and portability are required, and is applicable to be used as feed pump
for boilers, suction pump, vacuum pump, beer pump, water meter, and other
analogous purposes. To this end and when adapting the Invention for use as a
water pressure pump two cylinders of any suitable size are connected apart by
strong metal frames. Each cylinder is provided with a piston connected each with
the other by means of a piston rod, which rod is carried between the said frames.
The lower cylinder is provided with a valve casing, in which a valve is caused to
open and close inlet and outlet ports formed therein at suitable times by means of
the valve motion hereinafter mentioned. When the inlet port is opened the water
enters above the piston in the cylinder and forces down the same, whereby the
connected piston in the upper cylinder makes a corresponding stroke and will draw
into such cylinder water or air as the case may be, that is to say, if the connection
made with such cylinder be either with water or air. The herein before mentioned
valve motion is derived from the movements of the piston rod. On the said rod is cast
or formed thereon a projection, which comes in contact at every stroke of the rod
with one arm of a curved lever carried by a stud, which stud is carried by an arm

page_text: cast or formed with the frame. The said curved lever rocks with the stud at each
movement of the piston, through which action movement is transmitted to a cam
lever on the said stud, the said cam lever having projections on a part of its
periphery and corresponding recesses. A strong steel spring is connected to the
side of one frame adjacent to the stud or notch formed in the middle of the spring
bears against the projections or recesses of the said cam lever at suitable times
& effects the reversal or opening and closing each port alternately. When the
said projection on the piston rod comes in contact with one arm of the said curved
lever it rocks it on its fulcrum on the said stud and thereby moves the cam lover
with it until the projection thereon has pressed backwards the spring, after which
the pin of the spring enters a recess on the cam lever at the completion of each
stroke. When the lower port is opened by the recess on the lower part of the
slide rod gearing with a projection on the slide the water entering below the piston
and through the lower port forces the piston upwards, and the water that may be
above the piston at the time is forced by such action out by an exit port. This
action of the pump will continue so long as the water pressure admitted to the
lower cylinder remains constant. To the upper cylinder is connected inlet and
outlet valves, the inlet valves of which communicates with liquid at any
convenient part, from which it is to be drawn into the cylinder and delivered at
any other place by the outlet valve at the next stroke of the piston. When
constructing the pump for the special purpose of measuring liquids the top cylinder
with its valves is dispensed with and replaced by an index, which indicates every
stroke of the piston by means of connected levers; any ordinary and suitable
construction of index may be employed for this purpose. When constructing the
pump for the special purpose of raising beer from a lower level the bottom cylinder
is made according to the pressure required to work the pump, which is made to
exceed the pressure in the upper cylinder. The Invention can be applied with
advantage to other analogous purposes, as, for example, to the drawing and forcing
air and liquids, and may be worked by water or steam. When steam is employed
metallic pistons are used and the cylinder preferably jacketted.

"IMPROVEMENTS
IN PUMPING APPARATUS FOR BEER AND OTHER LIQUIDS, ACTUATED BY WATER
OR STEAM PRESSURE, APPLICABLE ALSO AS A WATER METER." A com-
munication from abroad by Messrs. Schläpfer and Sonderegger, of Lausanne,
Switzerland, Mechanicians.
The Invention relates to improvements in such pumping apparatus in which
small power and portability are required, and is designed for use as a feed pump
for boilers, suction pump, vacuum pump, or pump for raising or forcing beer, water
meter, and to other analogous purposes. To this end and when adapting the
Invention specially for use as a water pressure pump for raising or forcing beer,
two comparatively small cylinders are carried a suitable distance apart by a metal
framing. Each cylinder is fitted with a piston which pistons are connected with
a piston rod which passes through the ends of each cylinder cover. The cylinder
into which water or steam is admitted to force up the piston is provided with a
valve chest in which a valve is controlled by the hereinafter inentioned mechanism,
to open and close the inlet and outlet ports formed therein at suitable times. The
required opening and closing of the ports in the said cylinder is obtained from the
movements of the valve derived from the motion of the piston rod. On the said
piston rod is fixed or formed a stud or projection, which stud comes in contact at
every stroke of the piston with the arm of a curved lever. The said curved lever
rocks on a stud, to which stud is fixed a cam formed with three projections or
inclines and recesses, a strong steel spring being mounted on the side of the
frame on which a projection is fixed to bear against a projection or recess of the
said cam as the case may be. When the projection on the piston rod bears on
one arm of the said curved lever, it causes the said lever to rock on its fulcrum,
and the cam lever is moved until a projection thereon has passed the said springs
outwards and the projection on the spring enters a recess on the cam lever at the
end of each stroke and so in alternation. This action of the pump will continue
without any variation so long as the water pressure is slightly in excess of the air
pressure to be overcome. The second cylinder is provided with air inlet and
outlet valves. The inlet valve communicates with the outer atmosphere and the
outlet valve with the barrel or chamber into which air is to be forced. In a
modification of the above arrangement a pin or stud is formed on or connected to
the piston rod midway of its length which acts upon a cam formed with four arms
which cam is mounted on and carried by a short shaft. The lower arms of the
said cam are acted upon by the said stud on the piston rod, and the upper arms
move a tumbling weight to the right or left of the central axis thereof. The end
of the slide rod is slotted, in which slot a pin carried by the said cam works and
is shifted to the right or left according as the tumbling weight is moved over to
the right or left, and the valve opens or closes the ports. When adapting the
apparatus for indicating or measuring liquids the second cylinder or air chamber
is removed and a suitable index mounted in position to indicate the strokes of the
piston. When employing steam in lieu of water to work the piston, metallic
pistons are used and the cylinder jacketted.
And in order that the Invention may be better understood I have caused to be
appended hereunto a Sheet of Drawings marked with letters of reference, to which
I will now refer.
Fig. 1 represents a longitudinal section of a beer pumping or forcing apparatus

page_text: actuated by water pressure, and in which the required movements of the slide
valve are obtained from a cam formed with projections actuated by means of
a projection on the piston rod and spring; Fig. 2 represents a front view of an
apparatus designed to be employed as a feed pump for boilers, or suction pump,
vacuum pump, or beer raising or forcing pump; Fig. 3 represents a cross section
of Fig. 2 taken on the line **; Fig. 4 represents an ordinary form of indicating
apparatus which may be employed in combination with the apparatus when
intended for use for indicating or measuring the quantity of water passed through
the cylinder. In Fig. 1 the cylinder a, into which air is admitted and expelled,
is fitted or formed with inlet and outlet ports b, c, d, e, and with suction and
delivery openings f, g. The cylinder h formed with inlet and outlet ports i, j, for
water or steam, and with a discharge orifice k is fitted with a valve chest or
casing in which the slide m works. The said cylinders a and h are secured at a
suitable distance apart by means of a foundation framing n, which may be cast
or formed with brackets o in order to, bolt or secure it to a foundation wall if
required. Within each cylinder a, h, the pistons p and q are mounted, being
connected to reciprocate in unison by means of the connected piston rod r, which
passes through the stuffing boxes in each respective end cover of the cylinders.
A catch or projection 8 is formed on the piston rod to engage with at each
respective stroke of the piston with one or the other of the arms 1, 2, of the curved
levert to effect the reversal of the slide m at each stroke of the pistons p and q.
The said lever t is mounted on a stud u carried by the bracket v, on which stud
the cam w is jointed to the rod x, which rod is jointed to the slide m in the valve
box. The said cam w is formed with three inclined projections 1, 2, 3. The
projection 2 bears against a catch y formed on the spring by the movement of
the catch & acting on the arms of the lever t. The action of the apparatus is as
follows-The water entering at i forces the piston g in the direction of the arrow
until the piston has completed its stroke, during which time the piston p will
make a corresponding stroke and draw into the cylinder a atmospheric air through
the port b. When the piston rod r has reached the end of its stroke the catch s
will have lifted the arm of the lever t thereby the projection 2 of the cam w
into its highest position, and the projection v on the spring will have passed over
the incline 2 and entered the recess. A reverse action taking place of the slide
through the rod whereby the water enters through the port, and the pistons p
and q make a corresponding return stroke. The water above the piston q being.
forced through the discharge opening k, and visa versa. At each stroke of the
piston pair is drawn into the cylinder a through the port 6 from the suction pipe f
the air within the cylinder keeping down the valve c and forcing or expelling the
air through the valve e; when the piston is making its return stroke the air will
press down the valve b and be expelled through the valve a, and so on alternately.
A constant pressure of air is forced through the outlet g into a chamber or vessel
containing liquid, and which it may be required to raise, as, for example, beer from
casks or vessels. Fig. 2 represents an alternative arrangement wherein the
reversing of the slide is obtained from a catch s on the piston rod [r acting
upon the arm of a cam w, which cam acts upon a tumbling weight A. In this case
the cylinders a and h are formed and fitted with inlet and outlet ports and with
a valve box or casing. When the piston is making a downward stroke, as indicated
by the arrow, the catch a bears against the arm 1 of the cam w mounted on the
rod u until the arm 2 lifts the weight A¹ into a vertical position, when the weight
falls over to the opposite side as indicated by the dotted lines A¹, A². Buffers B
are mounted to the framing of the apparatus on to which the weight A falls when
it is lifted over the central axis as described. This movement of the tumbling
over of the weight A rocks the cam w on the stud u and moves it into the position
represented by the dotted lines. The slide rod x is formed with a longitudinal
recess on its outer end. The arm b² is mounted with the cam won the shaft u
and partakes of the rocking motion of the cam. On the outer end of the arm 6ª
a stud or anti friction bowl gears into the said slot and causes the slide rod x to

page_text: reciprocate to the right or left and to open and close the ports i and j alternately.
The apparatus continues its action uniformly untill the pressure arrived at is in
excess of the water or steam pressure within the cylinder h when the apparatus
will stop working until a less pressure is arrived at when its action commences
again self-actingly, which is an important advantage. In Fig. 4 a form of index
is represented for combination with the apparatus when intended to be employed
as a water meter. In this case the cylinder a is removed and the index x
mounted in place thereof. At every reciprocation or stroke of the piston rod r the
arm d' engages with a lever e¹ which transmits motion to the indicator < which
registers the number of times the cylinder h has been filled and emptied of its
contents. The Invention has been indicated and described when worked by water
pressure and applied to the pumping of beer from a lower to a higher level, but it
is equally applicable, with slight modifications, to be worked by steam or air
pressure and applied for other analogous purposes, as, for example, drawing and
forcing air, water, feeding boilers, forming a vacuum, and drawing or forcing oil
or other fluids.
