In the drawing A is an iron standard forming the sole support for the machine
having a laterally spreading base as shown, through which suitable bolts may be
put to secure the machine in any desired place or position.
Said standard is provided with a head 12, which is perforated horizontally to
form a valve-chamber therein, a portion of which chamber is cylindrical as shown
and a portion of which 14, is of enlarged concave form, and the latter-named part
of said chamber receives the water or steam-supply through the induction
passage h2, which is formed within standard A, its lower end n, being suitably
screw-threaded to provide for connecting a supply pipe therewith, the latter being
brought up under the base of the standard and completely concealed from view
thereby.
The cylinder disk B, is secured to the front or face side of the head 12, by
suitable bolts passing through bolt-holes in the latter one of which, 5, is shown in
Figure 2 and like holes in said disk.
The rear end of head 12, has secured to it by screwing or other suitable means
as shown, the cap K, a suitable packing ring 15, and packing 16, being interposed
between said head and cap to make a tight joint. The cap K, has a hole through

page_text: its rear side to allow the shaft E, to pass through it and a stuffing-box-nut J, on
the latter is screwed against suitable packing in a stuffing-box in said cap thereby
preventing leakage around said shaft. The eduction passage from the cylinder e,
through valve y, is provided by the chamber 15, in the cap K, the under side of
the latter having a screw-threaded opening m, therein which communicates with
said chamber, and a suitable pipe screwed therein carries off the exhaust steam
or water.
The valve y, consists of a central cylindrical portion, or shell, having on its rear
end the yoke 18, from which projects rearwardly the shaft E, above referred to, on
which is fixed the pulley H, on which a belt is put to connect the motor with
machinery which it is to drive.
The front end of valve y, is made of the form shown in Figures 1 and 4, or of
an enlarged, flaring shape, and the end thereof, 13, is finished true with circular
spots 2,2, thereon to constitute a bearing-face for the valve, a diaphragm 20,
extending from one side of the latter to one side of the shaft D, and closing said
front end of the valve partially, as shown in Figure 4, the said shaft D, extending
from the front end of the valve in a line with shaft E, through the hole 10, in the
cylinder disk B, in which it has a suitable bearing, and when the latter is bolted
to the head of the standard as above described the end of valve, y, on which is the
aforesaid bearing-face, is brought to a bearing against the inner side of said
cylinder-disk (see Figure 3). The said valve, and the pulley H, on the rear shaft
thereof, has a rotary motion imparted to it by its crank connection with the ring, w
through the intermediary of the cross-bar h, said ring being actuated by the
successive reciprocating movements of the pistons c, with which it engages, and
said valve alternately covers and uncovers the ports 8, through which water is
admitted to, and discharged from the cylinders e, the water in the valve-chamber
being free to enter such of said ports as are uncovered by the valve, and the water
is discharged from the ports of such cylinders as are covered by the valve into the
latter, and escapes through it to the discharge passage in the stand.
The pistons, c, are of the ordinary construction and are provided each, with a
friction roll, on which the ring w, has a bearing and a lip projecting above said roll
on each piston, behind which said ring is engaged, provides means for holding the
latter in proper position on the pistons.
The crank-pin, o, is fixed in the side of a half disk, d and to the straight edge of
the latter is bolted the strap o¹, the end of shaft D, being so clamped between said
half-disk and strap as to firmly secure the crank-pin to the shaft.
The bar h, is bolted to the ring w, as shown and the crank-pin o, has a suitable
bearing therein,
By means of the improved construction of the motor above described many of
the intermediate devices heretofore employed between the ring u, and the pulley
through which the motor imparts movement to machinery, are dispensed with and
the valve y, having the shaft D, on one end and the shaft E, on the opposite one
furnishes a direct means of transmitting the motion of the ring to the driving
pulley, thus obviating all other outside connections.
Rotary motion is given to the valve to cause it to control the proper entrance
and discharge of water into and from the cylinders, e, by means of the connection
of the valve with the ring through the intermediary of the bar, h, and the crank-
pin o. The ring rides on the pistons and has only one other connection namely,
with the valve, and by extending the rear end of the latter in the form of a
shaft E, through the cap K, the valve becomes practically, the driving shaft of the
machine.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
1. In a motor, a series of fixed cylinders radiating from a common centre, a
standard to which said series of cylinders is fixed having therein a valve-chamber

page_text: with which said cylinders communicate, induction and eduction passages, substan-
tially as described, communicating with said chambers, a rotary valve located in
said valve chamber having thereon a shaft extending rearwardly to receive a
driving pulley and a second shaft in a line with the former extending forward
between the converging ends of said cylinders, a series of pistons in the latter, a
ring encircling the outer ends of said pistons with which the latter engage, a bar
secured to said ring and extending transversely across it, and a crank secured to the
latter and to the end of said shaft which extends between the converging ends of
the cylinders, combined and operating substantially as set forth.
2. In a motor, the standard A, having the head 12, in which is the valve
chamber, said standard having the induction passage, h2, therein communicating
with said chamber, the cap K, secured to said head and having a shaft-bearing
therethrough substantially as described, and the chamber 17, therein having an
eduction passage leading therefrom, combined with the valve y, having a shaft on
each end projecting through opposite sides of the machine, the series of pistons, c,
the ring u engaging with the latter, and the bar h having a crank-connection,
substantially as described, with one of said valve-shafts, all as set forth.
3. In a motor, a standard having a suitable head, substantially as described,
forming a support for the operating parts of the machine and having a valve
chamber and the induction passage n², therein communicating with said chamber,
the series of cylinders, e, and pistons c, secured to said standard-head, the hollow
cap K, secured to the latter opposite said cylinders and having an eduction passage
therefrom, the ring u, engaging with said pistons, the bar h, secured to said ring,
combined with the hollow valve y, provided with a shaft on its opposite ends, one
of which passes through the cylinder head, and has a crank-connection with said
bar and the other extends through said cap and serves as the driving shaft of the
machine, substantially as set forth.
