We, WILLIAM ALBERT JORDAN (Blacksmith) and JEREMIAH ADAM BELTZ (Clergyman)
oth of Mulvane in the County of Sumner and State of Kansas, United States of America,
rading as Beltz and Jordan, a Firm doing business in Mulvane aforesaid; do hereby
leclare the nature of this Invention to be as follows:-
This Invention relates to improvements in steam engines and it consists principally
of a cylinder connected at its open ends with a steam chest, said cylinder being also
provided with ports leading from the steam chest to the interior of the cylinder at
points approximately one-third the length of the cylinder from the ends thereof and
pistons mounted to travel in said cylinder and connected with the main driving shaft
one of the pistons travelling between said ports and the open end of the cylinder.
The Invention also consists of certain parts and details and combinations of the
same as will be hereinafter fully described.
Upon a suitably constructed base or body is mounted a cylinder opening at its ends
into a jacket surrounding said cylinder and connected by ports with the interior of
the steam chest containing the usual slide valve reciprocated from the main driving
shaft in the usual manner. The slide valve operates over the live steam ports and the
exhaust ports and the inner ends of said live steain ports open into the cylinder at
points approximately one-third of the length of the cylinder from the ends thereof. In
the cylinder reciprocate three pistons of which the one piston moves in that
part of the cylinder located between the steam port and the left-hand end of the
cylinder while a second piston operates in the cylinder between the steam ports and
the third piston travels in that part of the cylinder located between the steam port
and the right-hand outer end of the cylinder. The left-hand piston is secured on a
piston rod extending through the outer head of the cylinder to connect with a
transversely-extending beam connected by longitudinally-extending rods with a cross-
head fitted to slide in suitable guideways on the base. The cross-head is connected
by connecting rods with crank arms or discs secured on the main driving shaft of
the engine. The middle piston is secured on a piston rod extending forwardly and
passing loosely through the right-hand piston and the hollow piston rod for said piston.
The outer end of the piston rod connects with a cross-head likewise fitted to slide in
suitable guideways on the base and in front of the cross-head previously mentioned.
The cross-head is connected with a crank arm secured on the main driving shaft of
the engine. The hollow rod of the right-hand piston is rigidly connected with the
cross-head previously mentioned so that the end pistons move simultaneously in the
same direction and in opposite directions to that of the middle piston it being
understood that the crank discs are arranged diametrically opposite each other for
that purpose.
The operation is as follows:-When the several parts are in the desired position the
one steam port is uncovered and takes live steam from the steam chest said live
steam passing through the port into the cylinder between the pistons close to the said
port but on opposite sides thereof. The other steam port is connected by the slide
valve with the exhaust so that any live steam in that part of the cylinder located
between the middle and right hand pistons will be exhausted on the movement of
said pistons towards cach other. The live steam passing between the left and middle
pistons drives the same apart in opposite directions and consequently movement is

page_text: given to the main driving shaft by-the cross-heads connecting rods and crank discs to
rotate said shaft. At the time the left hand piston nears the left end of the cylinder
and the middle piston nears the steain port the right hand piston has moved inwards
close to the port but on the opposite side on which the middle piston is located and
consequently the steam between the said pistons has been expelled or exhausted. By
this time the slide valve shifts to the left to connect the one steam port with the
exhaust port and to open the other steain port to the live steam in the chest. The
steam now passes into the cylinder through said port between the middle and right
hand pistons to force the same apart and to give another impulse to the main driving
shaft. As the right hand piston travels outward to the right the cross head causes
the left hand piston to travel iuward toward the middle piston until said pistons
again assume their adjacent position on opposite sides of the port. The above
described operation is then repeated.
It will be seen that by the arrangement described the steam acts at all times on
two pistons at the same time so that the steam is utilized expansively and to the
fullest advantage. It will further be seen that by having the opeu ends of the
cylinder connected with the interior of the steam chest there is no vacuum formed in
said open ends on the inward movement of the two outer pistons. The steam
jacket furnishes the live steam through ports from the steam chest around the
cylinder in which the pistons operate thereby maintaining the temperature of said
cylinder walls to prevent undue condensation of the steam which is being expanded
giving a higher average pressure. The movement of the end pistons to and fro
causes a forced circulation of the steam within the jacket from one end to the other.
The condensation within the stean jacket is carried off by an automatic water relief
cock placed under the rear end of the cylinder. By the arrangement described there
is no lateral strain between the cylinder and the pillow block boxing which strain
always exists in an old style engine. The engine is perfectly balanced by virtue
of having the connecting rods diametrically opposite on the crank shaft.

Improvements in Steam Engines.
We WILLIAM ALBERT JORDAN, Blacksmith, and JEREMIAH ADAM BELTZ, Clergyínan,
both of Mulvane, County of Sumner, and State of Kansas, U.S.A., do hereby declare 35
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 :-
In the steam engine of this invention a cylinder is connected at its open ends with
a steam chest, said cylinder being also provided with ports leading from the steam
chest to the interior of the cylinder at points approximately one third the length of 40
the cylinder from the ends thercof, and pistons are mounted to travel in said cylinder
and are connected with the main driving shaft, one of the pistons travelling between
said ports and the open end of the cylinder. In the accompanying drawings Fig. 1
is a sectional side elevation of an engine with the improvements of this invention,
Fig. 2 is a transverse section of the same on line 2-2 of Fig. 1 and Fig. 3 is a 45
sectional plan view of the same.
The improved steam engine is provided with a suitably constructed base or body A,
on which is mounted a cylinder B, opening at its ends into a jacket C, surrounding
said cylinder and connected by ports with the interior of the steam chest 1), containing
the usual slide valve E, reciprocated from the main driving shaft F, in the usual 50

page_text: thanner. The slide valve E operates over the live steam ports a and b and the
exhaust porta e, and the inner ends of said livo steam ports a and b open into the
oylinder Bat, points approximately one third of the length of the cylinder from
the ends thereof, as plainly shewn in Fig. 1.
In the cylinder B reciprocate the pistons G, G, G, of which the piston G moves
in that part of the cylinder located between the port a and the left hand end of the
cylinder, while the piston G' operates in the cylinder between the ports a and b, and
the other piston G travels in that part of the cylinder located between the port band
the right hand outer end of the cylinder.
The piston G is secured on a piston rod H extending through the outer head of the
cylinder to connect with a transversely extending beam H' connected by longitudinally
extending rods H' with a cross head I fitted to slide in suitable guideways arranged on
the base A. The cross head I is connected by pitmen J with crank arms or discs K
secured on the main driving shaft F of the engine, as will be readily understood by
reference to Figs. 1 and 3.
The middle piston G¹ is secured on a piston rod L extending forwardly and passing
loosely through the piston G and the hollow piston rod N for said piston G. The
outer end of this piston rod L connects with a cross head likewise fitted to slide in
suitable guideways on the base A and in front of the cross head- I as plainly illustrated
in the drawing.
The cross head I is connected by a pitman J¹ with a crank arm or disc K¹ secured
on the main driving shaft F of the engine. The hollow rod N of the piston Gle
rigidly connected with the cross head I previously mentioned, so that the pistons G,
G, move simultaneously in the same direction, and in opposite directions' to that of
the piston G, it being understood that the crank disca K, K, are arranged diametrically
opposite each other for that purpose, as indicated in the drawing.
The operation is as follows:-Whon the several parts are in the position in Fig. 1,
then the port is uncovered and takes live steam from the steam chest D, said live
steam passing through the port a into the cylinder, between the pistons G, G³, close
to the said port a, but on opposite sides thereof, as plainly indicated in said figures.
The other port b is connected by the slide valve E with the exhaust, so that any live
steam in that part of the cylinder located between the pistons G, G, will be exhausted
on the movement of said pistons toward each other. The live steam passing between
the pistons G, G, drives the same apart in opposite directions and consequently,
movement is given to the main driving shaft. F by the cross heads I, I', pitmen J, J
and crank discs K, K', to rotate said shaft F. At the time the piston G nears the
left hand end of the cylinder A and the piston G' nears the port b then the other
piston G has moved inward olose to the port b but on the opposite side on which the
piston G is located, and consequently the steam between the said pistons G, G, has
been expelled or exhausted. By this time the slide valve E shifts to the left, to
connect the port a with the exhaust port c and to open the port b to the live steam
in the chest D. The stent now passes into the eylinder through said port b between
the pistons G, G, to force the same apart and to give another impulse to the main
driving shaft. As the piston G travels outward to the right, then the cross head
I causes the piston G to travel inward toward the piston G until said pistons G, G¹
again assume their adjacent position on opposite sides of the port a, as indicated in
Fig. 1. The above described openstion is then repeated..
It will be seen that by the arrangement described the steam acts at all times on
two pistons at the anme time, so that the steam is utilized expansively and to the
fullest advantage. It will further be seen that by having the open ends of the
cylinder connected with the interior of the steam chest there is no vacuum formed in
said open ends on the inward movement of the pistons G, G.
The steam jacket C is to furnish the live steain through ports from the steam chest
D around the cylinder B, in which the pistons operate, thereby holding up the
temperaturo of said cylinder walls to prevent undue condensation of the steam which
is being expanded, giving a higher average pressure. The movement of the end
pistons to and fro causes a forced circulation of the steain within the jacket from one

page_text: end to the other. The condensation within the steam jacket is carried off by an
automatic water relief cock placed under the rear end of the cylinder. (Not shewn).
It will be seen that by the arrangement described there is no lateral strain between
the cylinder and the pillow block boxing, which strain always exists in an old style
engine.
The engine is perfectly balanced, by virtue of having the pitmen diametrically
opposite on the crank shaft.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is :-
1. A steam engine, comprising a cylinder connected at its open ends with a steam
chest, said cylinder being also provided with ports leading from the steam chest to
the interior of the cylinder at points approximately one third of the length of the
cylinder from the ends thereof, and pistons mounted to travel in said cylinder and
connected with the main driving shaft, one of the pistons travelling between the
ports and the other between the ports and the open ends of the cylinder, substantially
as shewn and described.
2. A steam engine, comprising a cylinder connected. at its open ends with a steam
chest, said cylinder being also provided with ports leading from the steam chest to
the interior of the cylinder at points approximately one third of the length of the
cylinder from the ends thereof, pistons mounted to travel in said cylinder and
connected with. the main driving shaft one of the pistons travelling between the
ports, and the other between the ports and the open ends of the cylinder, and a
slide valve controlling said ports in the steam chests, substantially as shewn and
described.
