Improved Distributing-motion for Double and Multiple Water-
pressure Engines.
I, EMIL KASELOWSKY, of 17/18, Chaussee Strasse, Berlin, Kingdom of Prussia,
German Empire, Royal Counsellor of Commerce, 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 an improved distributing-motion or valve-motion for
the use in double and multiple water-pressure engines, and the object of this
invention is to avoid in such engines the employment of complicated mechanisms
for effecting the distribution of the pressure-water in the two or more cylinders.
The improved valve-motion is characterized by its peculiar mode of operation,
which, briefly stated beforehand, consists in displacing the water-valves to their
position of rest, i.e. to their middle position by the movement of the piston of that
cylinder to which said valves belong, and in then displacing the latter further in
the same direction by means of the movement of the other piston, so that the
direction of movement of the former piston is reversed thereby. The advantage
gained by this manner of working, besides the simplicity of construction requisite
therefor, is, that always at least one cylinder is open to receive the pressure-water
during the time in which the other cylinder or cylinders is or are closed or in its
or their position of rest, so that shocks which would occur by checking the motion
of the water, and which could cause a break-down or destruction of the engine,
are effectively prevented.
In crder to make my invention more clear, I refer to the accompanying drawing,
in which similar letters denote similar parts throughout the different views, and in
which:
Figs. 1show plans of a double water-pressure engine provided with my
improved valve-motion, the cylinder as well as the valve-boxes being shown in
section. The construction is as follows:-
The piston-rod (Fig. 1) of the piston of cylinder 6 has fixed to it the cross-
bar c c', the arm e¹ of which embraces with its end the valve-rod d, and is adapted
to push alternately on two tappets secured to said rod d. Arm e of
cross-bar ce¹ is connected by means of a link e with a lever f fulcrumed at gi
said lever carries a sleeve hembracing the valve-rod i belonging to cylinder k, the
sleeve being adapted to push alternately against two tappets fixed to said rod i.
The piston-rod of piston k¹ of cylinder khas secured to it a cross-bar m m³, arm m¹
of this bar being adapted to push alternately on two tappets also fixed to
valve-rod i, the other arm m being hinged by a link n to a double-armed lever o
fulcrumed at tp;
lever o carries at the end of its shorter arm a sleever embracing
the valve-rod d, this sleeve being adapted to act on the tappets ³d also fixed to
said rod d. This construction, now, works in the following manner:
Supposed, piston 31 has reached its lefthand end-position, Fig. 1, the arm c¹ of
cross-bar ce has pushed shortly before on tappet d', and has, thus, caused a
displacement of valve-rod d, so that the slide-valves s s belonging to cylinder b
have got their middle-position and have, thus, closed the water-ways t t'; piston b,
consequently, is now in its position of rest.
Simultaneously, however, with valve-rod d, the other valve-rod i has been
displaced in the same direction by the impact of sleeve on tappet i¹, sleeve h
having been moved from arm c of cross-bar e c¹ by link e and lever f. The slide-
valves of cylinder k, which had kept the channels 23 closed, i.e. which had
bcen in their middle-position, have been moved then lefthand by rod i, so that said

page_text: chaunels t² t³ are opened, and piston k¹ is moved from left to right, as indicated by
arrow 5 in Fig. 1.
As soon, now, as piston k has reached the righthand end of its path, Fig. 2,
the valves are displaced anew by the impact of arm m² of cross-bar m m on
the tappet, the extent of displacement being such, that the channels t³ ³ are
closed, and piston k¹, thus, comes again to rest. Valve-rod d has been displaced at
the same time by the influence of sleeve on tappet ³, the sleeve having been
moved from arm m of cross-bar m m by link n and lever o, and the valves s are,
thus, brought to their left-hand end-position, so that piston & is set into motion in
the direction of arrow 6, Fig. 2.

If, now, this piston arrives at the end of this stroke, as shown in Fig. 3, the
cross-bar ce¹ is moved by piston-rod a in such a way, that arm pushes against
tappet of valve-rod d, and that at the same time sleeve h of lever pushes
against tappet of valve-rod i; both valve-rods are displaced thereby in the
same direction, and the valves are brought from the position shown in Fig. 2 into
that shown in Fig. 3, so that piston is set at rest, and piston ¹ is set into motion,
the latter piston moving then in the direction of arrow 7.
Piston having reached the end of its path, Fig. 4, causes the valve-rod i to be
displaced by the impact of arm m¹ on tappet ³, and causes also the valve-rod d to
be displaced by the impact of sleeve on tappet d', so that the valves are moved
now in such a way, that the pressure-water is hindered from entering cylinder k,
aud is led into cylinder b. Piston of this cylinder then moves in the direction
of the arrow S.
This piston after having finished its stroke is again in the position represented
in Fig. 1, and all the various movements and reversions of directions are repeated
now in exactly the same order as above described, from which results, that no
other or more complicated mechanisms are necessary for affording a secure and
reliable working of the engine.
By altering the distance between the two tappets working together with one
cross-bar, I may alter the lengths of the strokes, so that the engine may be adjusted
to the power at command, or to the amount of work required; and by altering
the position of the tappets with regard to the valve-rods, I may cause one piston
to begin its movement, or to have moved already a certain distance, before the
other piston comes to rest, so that the pressure-water is actually in constant motion,
and no dead end-play with its noxious results can happen.
I wish it to be understood that I do not confine myself to the employment of
my improved distributing-motion in engines with but two cylinders, as shown in
the drawing the same may be used with just the same advantage also in
multiple engines, and the configuration and arrangement of the valves and of the
organs for effecting the proper movement of the latter may vary according to the
type of engine.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. In a double or multiple water-pressure engine, a distributing-motion, in which
the water-valves of each cylinder are moved first by the piston of the cylinder
belonging to them, and then in the same direction by the piston of the other or. of
another cylinder, the channels of each cylinder being closed by the first movement,
and opened by the second movement of said valves in such alternation, that at
least one cylinder of the double or multiple engine is adapted to receive the
pressure-water, for the purpose as described.
2. In a double or multiple water-pressure engine, a distributing-motion, in which
the piston of each water-cylinder at or near the end of its stroke causes the closing
of the channels of its own cylinder, and the opening of the channels of the other
or of another cylinder, the water-valves of each cylinder being moved first by the
pision of the other or of another cylinder in such alternation, that at least one

for the purpose as described.
3. In a double or multiple water-pressure engine, a distributing-motion, in which

piston of the cylinder belonging to them, and then in the same direction by
the piston of the other or of another cylinder, the channels of each cylinder being
closed by the first movement, and opened by the second movement of said valves,
the valves acting on the channels in such a manner, that at least one cylinder of
the double or multiple engine is adapted to receive the pressure-water, for the
purpose as described.

of another cylinder, the piston of each cylinder causing by said impacts first a
displacement of the valves of the other or of another cylinder, and then a displace-
ment of the valves belonging to its own cylinder, the valves acting on the
channels of the cylinders in such a manner, that at least one cylinder of the
double or multiple-engine is adapted to receive the pressure-water, for the purpose
as described.

respectively) of the cylinder (bor k respectively) belonging to them, and by a
lever (o or respectively) connected by a link (n or e respectively) with a cross-
bar (m m or c e respectively) fixed to the piston-rod (or a respectively) of the
other or of another cylinder (k or b respectively) the piston (1 or k¹ respectively)
of each cylinder (b or k respectively) causing by said impacts first a displacement
of the valves (83 or s s' respectively) of the other or of another cylinder (k or b
respectively) and then a displacement of the valves (s s¹ or respectively)
belonging to its own cylinder (b or k respectively) the channels (t' t³ or t¹ respec-
tively) of each cylinder (k or b respectively) being closed by the first movement,
and opened by the second movement of said valves (s² 3 ors s' respectively), the
valves acting on the chanuels in such a manner, that at least one cylinder of the
double or multiple engine is adapted to receive the pressure-water, substantially
as described.
