- 4 Claims.
My invention relates to engines and an object
of my improvements‘is an improved apparatus for
communicating a rotary motion to a shaft.
In the accompanying drawings, I have shown
an engine in which it is assumed that steam is to
be used, though compressed air would be equally
appropriate.
-
Fig. 1 is an elevation of an engine embodying
10
my invention;
Fig. 2 is a sectional elevation;
Fig. 3 is a detail section, on the line 3--3, Fig. 4;
Fig. 4 is a detail section of the valve mechanism
to an enlarged scale, the parts being in position
for the admission of steam to the cylinder;
15 ‘ Fig. 5 is a view similar to Fig. 4, the parts being
in a position for exhausting the steam from a
cylinder;
Fig. dis a section on the line 6-6, Fig. 2, toan
enlarged scale, the central casting being broken
20 away;
Fig. 7 is a detail elevation looking from the line'
1—'|, Fig. 2; and
Fig. 8 is a section on the line 8—8, Fig. '7.
I is an enclosing casing which may be mounted
25 upon a pedestal la. 2 is an‘ annular casting
within the casing I at the center thereof and in a
plan-e at right angles to the axis of said casing,
its periphery engaging the inner surface of said
casing. 3 indicates cylinders, four of which are
30 shown though any number may be used. Said
cylinders are‘ placed around the annulus 2, at
equal angular distances apart and extend upon
both sides of said casting, with their» axis at right
angles to the same. 2a is an annular chamber
35 extending throughout the casting 2. The cyl
inders 3 pass through said annular chamber as
shown in Fig. 3.
4 is a shaft extending axially through the
casing I and bearing in said casing. 5 is a cam
40 on the shaft 4, centrally of the casting 2. 6 in
dicates tubes passing radially through the annu
lar walls of the chamber 2a and through the cyl

of the plungers 1 adapted to register with the
port I0 at the outer end of the stroke of the
plungers ‘I and with the ports I I at the inner ends
of said stroke. I4, I4 are pistons in the cylinders
3 traveling in opposite directions from positions 5
at the center of said cylinder. I5, I5 are piston
rods pivoted to and extending from, the pistons
I4--l4.
I6 and I‘! (Figs. '7 and 8) are discs secured
eccentrically to the shaft 4 at 180 degrees from 10
each other. I60, and I'Ia are rings surrounding
the discs I6 and I‘! respectively and connected to
said discs through ball bearings as shown in
Fig. 8.
_ I8 is a cylinder between the rings Mia and lid 15
having arbors I8a and I8!) extending from its
opposite faces 180 degrees apart engaging re
spectively in bearings in said rings.
I9 are bars with spherical ends located between
the rings I6a and Ila and bearing at their ends
in suitable cavities 20 and 2I in the adjacent faces
of the rings I60. and I ‘la.
'22 are bars integral with, and extending from
the centers of, the bars I9 and at their other
ends they are connected by universal or ball and
socket joints to the ends of the piston rods I5.
The operation of the above described apparatus
is as follows:
Steam under pressure is admitted to the annu
lar chamber 2a through a pressure inlet 21).
The parts being in the positions shown in Fig. 3,
the pistons I4 are at the center of the cylinder 3.
The plunger 1 then has been forced by the cam
5 into the position shown in Fig. 4, the ports II]
and I3 registering. admit steam through the 35
plunger 1, tube 6 and port I2 to the cylinder 3
between the pistons I4, forcing said pistons out
ward, oscillating the connecting rods I9 and 22,
pressing inward on one of the rings I6a and Na
and outward on the other of said rings. Said
rings act through the ball bearings upon the
eccentrics I6 and H to rotate the shaft 4. The

3. In an engine, the combination of a shaft,
understood that numerous details of the con
struction may be altered or omitted without de
parting from the spirit and scope of the inven
tion as disclosed and. claimed, and that I do
not desire to limit the invention to the exact con
struction herein set forth.
I claim:
1. In an engine, the combination of a shaft,
two eccentrics on said shaft angularly spaced
10 from each other, a ring surrounding each of said
eccentrics and revoluble with reference thereto, a
bar pivoted to said rings at its ends and means for
oscillating said bar so that its ends shall move
said rings in a path adapted to rotate said ec
15
centrics.
,
2. In an engine, the combination of a shaft,
two eccentrics on said shaft, a ring surrounding
each of said eccentrics and revoluble with refer
ence thereto, adjacent faces of said rings being
20 provided with cavities, a bar extending between
said rings, its ends engaging in said cavities, and
means for oscillating said bar so that its ends
shall move said rings in a path adapted to rotate
said eccentrics.
two eccentrics on said shaft angularly spaced
from each other, a ring surrounding each of said
eccentrics, a bar pivoted to said rings at its
ends, a lever extending from said bar at an inter
mediate point thereof and means for oscillat
ing said lever so that the ends of the bar shall
move said rings in a path adapted to rotate said
eccentrics.

4. In an engine, the combination of a shaft, 10
two eccentrics on said shaft angularly spaced from
each other, a ring surrounding each of said ec
centrics, a plurality of bars angularly spaced from
each other extending between said rings, the
opposite ends of each of said bars pivotally en 15
gaging said rings, a lever extending laterally out
ward from an intermediate point of said bar, a
plurality of cylinders lying parallel to said shaft
and pistons in said cylinder connected to said
levers to actuate'the same.
