page_text: I, ALA BEÖTHY, of Jasz Apathi, Kingdom of Hungary, 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 construction of locomotive engine, more particularly,
for use with express trains, by means of which greater speed can be obtained than'
was heretofore possible, without reducing the stability.
I will proceed to describe the said invention with reference to the accompanying
drawings in which Fig. 1 shows a side view of the locomotive engine with the,
two truck frames, shewing the side frames of the engine. Fig. 2 is the same view
with the framework. broken away for shewing the position of the cranks and,
cylinders; Fig. 3 shews a longitudinal section of the boiler; Fig. 4. is a cross section
of the same on line XX, and Fig. 5 is a cross section taken, on the right hand side
on the line Z Z, and at the left hand side on the line W. W.
The framing A of the engine rests on the two driving axles B. B¹ and, with parts:
extending beyond the body of the engine on two trucks CC of which the former
is situated beyond the front end and the latter beyond the back end of the body;
of the engine.
The truck C serves at the same time as tender. The connection of the engine
framing with the truck frames will be described below.
The, boiler consists. of two cylindrical shells D D of which the one is situated
above and the other below the driving axles, and these shells are connected by a
branch E situated behind the rear driving axle. The firebox F is common to both
boiler shells, and the smoke boxes G G of both are connected by a vertical
branch pipe H in front of the front driving axle. This connecting branch is fixed
by screw bolts and can be removed, so as to enable the boiler to be removed from
the framing when required, and also to facilitate the removal of the axles. For
the same purpose the rear bracing of the framing is made removeable.
The steam cylinders I I¹ (four in number) are arranged two on each side of the
engine, each end of each one of the two coupled driving axles being driven by one of

page_text: the cylinders by means of cranks that are arranged at right angles to each other at the
two ends of each axle, while the two cranks on the two axles at one and the same
side of the engine are placed at an angle of 180° to each other. This arrangement
obviates to a great extent the disturbing action of the masses that are in motion
relatively to each other, and enables the balance weights to be reduced to slight addi-
tions to the rims of the wheels. The slide valves of the cylinders situated on the
same side of the engine are worked by one and the same Stephenson Link motion';
for this purpose it.is sufficient to introduce between the link and the connecting rods
of the slides two elbow levers connected by rods.
The connection of the framing A of the engine with the rear truck frame is effected
in a manner similar to that of the "Vassen construction of engine," but with the
essential difference that the inclined planes are replaced by steel balls which, contrary
to the inclined planes, are intended to permit of a free lateral displacement of the
rear truck frame. $
The connection of the engine frame with the front truck frame is effected in
precisely the same manner as in the "Vassen" construction of engine.
The details of the connection of the engine framing with the rear truck frame are
shewn at Figs. 6, 7 and 8.
Fig. 6 shews a sectional side view to an enlarged scale. Fig. 7 a sectional plan,
and Fig. 8 a sectional back view; a is the pivot of the rear truck frame, b, the pivot
on the engine framing, ce is the connecting link, d d is the bearing surface,
forged in one piece with the connecting link, e e are the balls, and ff the ball
bearings.
The entire engine together with the front truck frame is enclosed by a casing of
thin sheet metal which is formed wedge-shape in front in order to reduce the resistance
in passing through the air.
The axles of the truck frames have each four bearings, two inner ones, and two
outer ones, in order to reduce the load on the unit of bearing surface. →
Having now particularly described and, ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim'is':―
1. An improved construction of locomotive engine in which the boiler consists of
two cylindrical shells D D¹ one of which is situated above and the other below the
driving axles, and which have a firebox F common to both and are connected together
by a branch E situated behind the rear driving axle B₁ while the two smoke boxes G G¹.
are connected by a branch H in front of the front driving axle, substantially ás
herein described with reference to the drawings.
2. The arrangement of a truck beyond the front end and another beyond the rear
end of the body of the locomotive engine, which trucks carry extensions of the
framing A of the engine, substantially as herein described.
3. Connecting the rear truck frame C₁ with the engine framing A in such manner
that the rear end of 'the engine frame is laterally shiftable on balls on the truck frame,
substantially as herein described.
Dated 'this 19th day of February 1889.
