COMPLETE SPECIFICATION.
Improved Pump or Apparatus for Forcing or Projecting Water.
I, JOSEF PILECKA, of Wsetin, Moravia, in the Empire of Austria, Watch Maker,
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 improved force pump or water
ejector two forms of which are shown in the accompanying drawings.
On Sheet I one pattern is shown.
Fig. 1, side elevation.
Fig. 2, front elevation with the front casing a removed.
Fig. 3, section on the line a of Fig. 2.
This apparatus is enclosed and works by means of a piston A which rotates in a
cylindrical vessel B, whereby the dimensions of the chambers formed at the sides of
the piston A. in the vessel B are alternately enlarged and reduced and the water is
thereby drawn into the vessel B and forced into the chamber or reservoir C. The
apparatus is actuated by means of a fly wheel S the shaft w of which is connected
to this piston (see also Sheet II, Fig. 5).
In order to allow of the working of the apparatus being more clearly understood
the position of the piston A shown in Fig. 3, may be regarded as the starting
point.
By rotating the piston in the direction of the arrow a partial vacuum is formed
in the suction chamber or part a, see Fig. 34, by reason of a sliding plate & which
constantly fits or presses tightly against the rotating piston and shuts off the
suction chamber a from the pressure chamber ẞ. In consequence of this, the
atmospheric air forces the water through the (two) suction orifices c into
the chamber (1,
for this purpose hose or suction pipes are of course attached to
these openings c in the usual manner the ends of which pipes open under the surface
of the water in a reservoir or the like. When the piston has completed a revolution
it raises or forces upwards the water contained in the vessel B, which is thereby forced
or raised in the direction of the arrow into the chamber C. At the same time a
vacuum is thereby created in the suction chamber a and the water is again drawn
in, and ultimately again ejected.
As shown in Fig. 1, the vessel C is provided with nozzles d and d¹ for the
attachment of tubes or hose pipes in which cocks e and fare inserted. The cock f
has the form of a three way cock, and two nozzles h h are screwed into the cock-
As the mode of
case g to which the hose-pipes are attached in the usual manner.
construction of the cocks, suction pipes, hose pipes and similar apparatus for fire
engines is well known no further reference will be made to the same either in the
Specification or the drawing.
The device for regularly operating the sliding plate bis constructed in the
following manner. The disc with its guide projectionsj is first placed loosely on
the shaft w (see also Fig. 6, Sheet 11). A disc k having a contact-pink is then
keyed on the shaft w, and then the slide or pusher with its slide-cheeks is
inserted in the guide projections of the plate i and covered with a plate m (which
has a contact pin m³) keyed on the shaft w.
The pusher is at or near its centre cut out in a circular form, and has at its
inner periphery a projection (small cam) n and a recess o situated diametrically
opposite thereto.
This pusher has further at its right end, a turned-up lug P, between which and
the slide cheeks l' of the pusher, the piu y of a crank r, projects.

page_text: This crank is keyed on a small spindle s carried in the frame, which (spindle) is
firmly connected with a case or sleeve t placed inside the apparatus.
This case or sleeve las lugs which project into slots 't, of the slide plate b,
and are movably connected with the plate b by means of a rod or wire t³.

It is thus evident that on the pusher moving backwards or forwards, the pin
or bolt of the crank makes an oscillating movement, which is transferred to the
slide plate by means of the spindles and the lugs t' on the sleeve t, and con-
sequently the slide plate b moves horizontally backwards and forwards. The
movement, or stroke of the crank pin 7 is calculated in such a way, that the slide
plate presses tightly against the piston A in every position of the latter, and thus
shuts off the suction chamber a from the pressure chamber ẞ Fig. 3^.
b
In order to obtain a horizontally backward and forward motion of the pusher 1,
the above nained contact pins m¹ of the discs km are employed. The pin k
of the inner disc, by striking and pressing against the projection n of the pusher,
moves this latter into the extreme left position (see Fig. 1, where the pin is just
leaving the projection) whilst the pin m' (shown in dotted lines) of the outer disc-m,
comes into action when it engages in the recesso of the pusher. This pin also
moves forward by the rotation of the disc, and carries the pusher with it and only
disengages from the recesso after it has impelled or carried the pusher into its
extreme right position (in the drawing the tracks of the two pins k¹ m' are shown in
dotted-line circles with arrows.. The upper disc m with the pin m³ is in the drawing
supposed to be removed in order to expose the mechanism). The recess in the
pusher is to allow for the passage of the pin when returning.
The modification shown on Sheet II differs from the preceding one merely
through another mode of construction of the division plate or piece for the suction
and pressure chambers with a corresponding modification of the operating mechanism
belonging thereto (see Fig. 4 side view, Fig. 5 section on y y of Fig. 6, Fig. 6 section
on of Fig. 5 or on of Fig. 7).
In this case the shutting off piece is curved in form, and (see also Fig. 7, plan
view of the shutting off mechanismn) is provided with round lugs 62, which are
inserted in suitable slots in the bar 3, and are movably connected with this latter
by means of a round rod inserted therein.
The shutting off piece is suspended by means of a round bar or pin bb and
connecting rod 8, which is movably attached to a crank e' keyed to the spindle 67
(Figs. 4 and 5).
This spindle is placed in a support L, and has at its end a square or rectangular
piece on which the crank is fitted, whilst the pin 6 of the latter projects into the
slot of the connecting piece 610, attached to the pusher 1.
:
The crank 8 is caused to oscillate by means of the up and down movement of
pusher, which is transferred through the spindle 6, and crank c', to the connecting".
rod 6, and from this latter to the division 'plate or shut off piece b¹, which operates
in a similar manner to the slide plate 6 described in the first arrangement:"
The shutting off piece & fits constantly tight against the piston A, and divides.
the chest into two chambers, viz. the suction chamber a and pressure chamber ß.
'
In order to render the suction chamber more perfectly tight; a washer plate '6",
is arranged inside the apparatus, which (washer) presses against the shutting off
piece b, and a tight joint is insured by means of inserted packing strips having a
spring action by means of a spring placed in the recess b

As before mentioned the pin & performs a rising and falling movement whilst in
the former apparatus, it made a horizontal backward and forward movement. 11
For this reason the motion of the pusher 1, in this modified apparatus, must be in
a different direction, that is to say upwards and downwards.
This is brought about by the disc with its guide lugs j being in this case 'placed
vertically on the axle w (about 90° opposed to the position shown in the former
case) which position the pusher also correspondingly assumes. The arrangement
of the discs k and m, with their "pins m'; as well as their mode of working,
remains the same as previously described. The pin of the inner disc k forces the

page_text: pusher downwards (by coming in contact with the projection n), whilst the pin m²
of the outer plate m carries the pusher with it that is to say lifts it by striking on
the edge of the recess O.
In Fig. 4 of the accompanying drawing the position is shown where the pin k¹ is
just leaving the projection n, after it has brought the pusher into the lowest
position. The next moment the pin m' comes into play.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is -
1. A pump or apparatus for forcing or projecting water constructed with a
piston A rotating in a cylindrical chest B, against which (piston) a horizontal slide
plate constantly tightly presses, dividing the interior of the chest B into a suction
chamber fly and a pressure chamber ẞ, whilst both the suction through the opening C,
and also the raising of the water takes place by means of the piston A, the area of
chambers a and ẞ of the chest B being alternately enlarged and reduced.
2. In this apparatus, a device for constantly pressing the slide plate b tightly
against the rotating piston A, consisting of a pusher arranged in horizontal
guides j, which is moved to left or right, by means of the pins ¹m inserted in the
plate km keyed on the motor shaft and which thereby sets in oscillation a crank
pin which imparts a backward and forward motion to the slide plate b, by means
of the crank r, spindle s, and lugs t, which are connected with this slide plate by
means of a pin ta inserted therein.
3. A modification of the above described apparatus, consisting of the arrangement
of a curved division plate or shut-off piece 6 rotating on pivots 6, which (piece)
also constantly presses ou the rotating piston A, and the raising and lowering of
which, is effected by means of the pusher 1, arranged vertically, and operated by
means of the pins m¹ through the intermediary of a crank 68, the oscillating
motion of which is conveyed to the spindle, crank e', and connecting rod to, which
latter raises and lowers the shutting off piece in accordance with the movements
of the piston, whilst a washer plate 6" fitting tightly on the piece b¹, shuts off the
suction chamber a.
