LESLIE X. SHERIDAN, OF EL PASO, TEXAS.
ROTARY ENGINE.1,302,233.
Specification of Letters Patent. Patented Apr. 29, 119.
Application filed Kay 31, 1917. Seria 1No. 171,950.To all whom it may concern:
Be it known that I, LESLIE M. SHERIDAN,
a citizen of the United States, residing at
El Paso, in the county of El Paso and State
5 of Texas, have invented a new and useful
Rotary Engine, of which the following is
a specification.
The device forming the subject matter of
this application is adapted to be employed
10 as a rotary engine, as a pump for liquids,
as an air compressor, as a vacuum pump and
for other purposes, but for convenience in
description, it will be presupposed that the
structure is employed as a rotary engine.
15 The invention aims to provide novel
means whereby rotary movement is im-
parted to the shaft, and to improve gener-
ally and to enhance the utility of devices of
that type to which the present invention ap-
20 pertains.,
With the above and other objects in view
which will appear as the description pro-
ceeds, the invention resides in the combina-
tion and arrangement of parts and in the
25 details of construction hereinafter described
and claimed, it being understood. that
changes in the precise embodiment of the
invention herein disclosed can be made with-
in the scope of what is claimed, without de-
30 parting from the spirit of the invention.
In the accompanying drawings:-
Figure 1 shows in vertical section, a de-
vice constructed in accordance with the
present invention, parts appearing in sec-
35 tion;
Fig. 2 is a vertical section in which the
cutting plane is disposed at right angles to
the cutting plane of Fig. 1;
Fig. 3 is a vertical section showing a mod-
40 ified form of the invention;
Fig. 4 is a vertical section of the struc-
ture shown in Fig. 3;
Fig. 5 is a horizontal section of the de-
vice delineated in Fig. 3, the line 3-3 of
45 Fig. 5 denoting the cutting plane in which
Fig. 3 is taken; and
Fig. 6 is a sectional detail illustrating the
means whereby rotation is imparted im-
mediately to the shaft.
50 In that form of the invention which is
shown in Figs. 1 and 2, there is provided a
pair of side plates 3, having sleeves 2. A
ring 5 is disposed between the side plates 3
and is attached thereto by securing elements
55 6. The side plates 3 and the ring 5 form
the stator of the engine. A casing 7 is as-sembled with>the-stator and includes an edge
portion 8 cooperating with the ring 5 of
the stator to form a water jacket, the en-
trance and the exit for which are repre- 60
sented by suitable connections 9 carried by
the part 8 of the. casing. Disks 10 cooperate
with the side plates 3 to form side water
jackets.
The sleeves 2 of the stator carry bushings 65
11 in which is journaled for rotation a shaft
12 carrying a fly wheel 14, the shaft 12 be-
ing eccentrically mounted in the stator. The
shaft 12 is provided with projecting arms 15.
Disposed within the stator is a pair of pis- 70
tons, each including a hub 16 and a body 17,
the body 17 of one piston overhanging the
hub 16 of the other piston, as clearly shown
in Fig. 1. The outer edges 18 of the bodies
17 of the pistons are curved to conform to. 75
the inner curve of the ring 5 of the stator. -
The inner edges of the hubs 16 of the pis-
tons are recessed to receive packing rings
19. The outer surfaces of the pistons carry
packings 20, pressed outwardly by springs 80
21 to cooperate with the side plates 3. In
the ends of the body portions 17 of the pis-
tons are formed recesses 22 which at times
cooperate to form an expansion chamber 23,
as shown in Fig. 2. The charge in the ex- 85
pansion chamber 23 may be ignited by a
plug 24 carried by one of the side plates 3,
or in any other suitable manner. One of
the side plates 3 is provided with an inlet
port 25 and with an exhaust port 26 as indi- 90
cated in Fig. 2. In the peripheries of the
hubs 16 of the pistons, slots 27 are formed.
Blocks 28 are adapted to work in the slots
26 and are pivoted at 29 to the pistons. The
blocks 29 are provided with guide passages 95
30, receiving the arms 15 of the shaft 12
slidably.
The side plates 3 of the stator are pro-
vided with oil ports 31, communicating with
pipes 32, the pipes being adapted to supply 100
a lubricant for lubricating and cooling the
working parts of the engine.
Let it be supposed that the parts are ar-
ranged as shown in Fig. 2, and that a charge
has been compressed in the chamber 23. 105
When the charge in the chamber 23 is ig-
nited, the pistons tend to separate, the
blocks 28 pivoting on their mountings 29
and sliding on the arms 15 of the shaft 12,
rotation being imparted to the shaft in this 110
way. The charge in the chamber 23 tends
to expand through an are of 180 degrees,
