COMPLETE SPECIFICATION.
Improvements in Motors worked by Gas, Steam, Compressed Air,
Water, or the like.
I. PAUL BRUDER, of 9, Hasenhaide, Berlin, Germany, Engineer, 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 new system of motor which is operated by gas,
water compressed air etc., without "piston distribution," and it consists of two
cylinders, and of a motor shaft and is provided with spiral or helical passages for
the motive fluid and with the necessary devices for admission and exhaust.
The accompanying drawings illustrate by way of example, one form of con-
struction of this invention, and in these drawings, Figure 1 is a horizontal section
and Figure 2 is a vertical section of the new arrangement. Figures 3 and 4 are
detailed views.
The arrangement of the several parts of the motor is the following:-The two
cylinders A and B are fitted one in the other in such a manner that the outer
cylinder A completely surrounds the inner cylinder B and renders it absolutely
fluid tight towards the outside. Between the cylinders there is provided an empty
space C. In the evlinder B and around the motor shaft there is arranged a
continuous helix E having a slight inclination which is formed with oblique
sides that are arranged at short intervals and that form lateral branches in such
a manner as to produce angular divisions on the helix. This latter makes a
tight joint with the walls of the cylinder B. The said cylinder is closed on its
sides by the cover g in which there is formed at a short distance from the
shaft an annular groove which as shown in Figure 3 is provided with two
rows of elongated holes that are arranged in such a manner that the holes of
the inner series are situated in the intervals between the holes of the outer
series, whilst the ends of the holes extend beyond one another. This groove may
also be arranged as shown in Figure 4 around the cylinder which in this case
must be provided with the said elongated holes. In the groove there is intro-
duced and ground in to fit, a valve ring k, which is vertical to said groove and
closes the elongated holes i. This ring is immovable and is fixed to the outer
cylinder A. In the valve ring & there is formed a transverse hole of a length
corresponding to the height of the two series of holes of the groove,
in such a manner that when the cylinder and the groove rotate, the
steam or the like will be able to pass into the cylinder alternately through a
hole of the outer series or of the inner series. The valve ring is connected
to the admission passage m that forms a spring, and thus has a powerful
tendency to draw the ring into the groove. On the two sides of the cock o of
this admission passage m there is connected a slide valve box n through which
passes the admission pipe and which is provided also with lateral discharge
apertures p. The arrangement of the parts is such that when the cock is
turned, the slide closes the first aperture and opens at the same time the second
one, and inversely the two apertures of admission and discharge can thus be

page_text: closed simultaneously. This produces the stoppage of the engine. The apparatus
operates as follows:-The motive agent (steam, gas etc.) enters through the
admission passage m through the opening of the valve ring and the elongated
holes of the groove into the cylinder B: it acts by pressure, as in a turbine,
upon the angular helicoidal divisions which it meets, and it forces them to move
downwards. Then the fluid passes into the following divisions and so on until
it exhausts. This takes place with a continuous admission of steam etc. without
interruption, in such a manner that the cylinder B is caused to rotate with the
motor shaft. By the action of this spiral conduit, the motive force is much
more completely utilised than in the case of piston distributing apparatus. The
steam, etc. escapes from the other end of the helix through the elongated holes i
which are arranged as above described, and it then passes through the valve
ring into the passage m and passes to the outside through the open discharge
aperture of the slide ». As the cylinder is provided on both sides with similar
admission and discharge apertures, the helix can always be caused to rotate at will
in one or the other direction by merely turning the cock 0. When the cock is
turned to the right the slide opens the admission, and closes the right hand
exhaust. By turning the cock to the left the admission is closed and the exhaust
is open and vice versa.
The motive apparatus is particularly suitable for use
in vehicles, motor cars, boats or the like.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is―
(1) The improvements in motors worked by steam, gas, water, compressed
air or the like which consists in two cylinders which are enclosed fluid-tight the
one in the other, as set forth.
(2) The improvements in motors worked by steam, gas, water, compressed air
or the like which consists in a helix which is fitted in the inner cylinder around
the motor shaft and is provided with projecting ribs so as to form branches, said
helix being caused to rotate by the passage of a motive agent, as set forth.
(3) The improvements in motors worked by steam, gas, water, compressed air
or the like which consists in an admission device characterised by a valve ring
which is fitted in a circular groove provided round the shaft in the cover of a
cylinder and which is formed with two rows of elongated holes, or which may be
arranged around the wall of the cylinder. as set forth.
(4) The improvements in motors worked by steam, gas, water, compressed air
or the like which consists in a slide which opens on one hand and closes on the
other hand simultaneously the admission and exhaust apertures, in such a manner
as to allow of obtaining forward or backward running of the motor by the use
of a helix, the whole with the object of realising a more complete utilisation and
consequently a much greater economy of the motive force than in the motors
known at present, and at the same time a considerable reduction in space and
cost, and of producing an engine which is particularly advantageous for motor
cars. boats or the like, as set forth.
(5) An improved motor worked hy steam, gas, water, compressed air or the
like, substantially as above described and shown in the accompanying drawings.
