FRANK REAUGH, OF OAK CLIFF, TEXAS.
PUMP OR MOTOR.Specification of Letters Patent.
Patented Apr. 27,1915.
Application filed Narch 2, 1905. Serial No. 248,054.
To all whom it may concern:
Be. it known that I, FRANK REAUGH, a citi-
zen of the United States, and a resident of
Oak Cliff, in the county of Dallas and State
5 of Texas, have invented a new and Improved
Pump or Motor, of which the following is a
full, clear, and exact description.
The invention is designed particularly as
a pump or compressor, although by a mere
10 reversal of its operation it may serve as a
motor, as will be fully understood by persons
skilled in the art.
The apparatus to which my invention re-
lates is of the rotary type, comprising an
15 enclosing shell or casing with inlet and out-
let openings or ports in its walls, preferably
at the sides near the periphery, in which
casing is arranged. a piston blade or blades,,
the casing and blade having relatively cir-
20 cular movement, and the blade in addition
having a turning movement around an axis
radial of the casing. In the type of the in-
vention here illustrated, the casing is sta-
tionary, the blade or blades having both cir-
25 cular and turning movements. Interiorly
the casing has a definite form, and the pis-
ton blade is associated with positive gearing
for causing it to turn around said radial
axis at a fixed rate corresponding exactly to
30 the interior form of the casing, so that not-
withstanding the turning of the piston blade
it maintains true contact with the inner walls
of the casing, thus preventing leakage, the
compression or other action of the appa-
35 ratus depending upon the aforesaid form
and movements of the parts.
Reference is to be had to the accompany-
ing drawings which illustrate as examples
several types and applications of my inven-
40 tion, in which drawings like characters of
reference indicate like parts in the several
views, and in which-
Figure 1 is a sectional elevation on sub-
stantially the line 1-1 of Fig. 2. Fig. 2 is
45 a cross section on the line 2-2 of Fig. 1;
Fig. 3 is a horizontal section on the line
3--3 of Fig. 1; Fig. 4 is -a detail perspec-
tive showing one of the piston blades which
are employed in the form of the invention
so illustrated in Figs. 1, 2 and 3; ,Fig. 5 is a
fragmentary section taken along the arc-shaped line 5-5 of Fig. 1, and illustrating
the top portion of the side walls of the cas-
ing near its periphery, and also the rotating
web and one of the piston blades; Fig. 6 is 55
a fragmentary section taken along the arc-
shaped line 6'--6 of Fig. 1, and showing por-
tions of the side walls of the casing near the
bottom thereof, and illustrating the inlet
and exhaust ports and also.the rotating web 60
and one of the piston blades; Fig. 7 is a sec-
tion similar to Fig. 6 illustrating a modifica-
tion of the apparatus; Fig. 8 is a section
showing a modification in the means for
bringing about the turning movement of the 65
piston blades; Fig. 9 is a section on the line
11-11 of Fig. 10 illustrating a further
modification of the invention; Fig. 10 is a
horizontal section of same on the line 12-12
of Fig. 9; and Fig. 11 is a detail section of 70
the rotating element of the form shown in
Figs. 9 and 10.
Reference will first be had to Figs. 1 to
6. The casing is formed with two side
walls, each comprising tubular portions or 75
sleeves 15 connected to rounding hub-like
portions 16, outward from which are the
side walls proper 17, as shown best in Fig. 2.
18 indicates a base which may be formed
integral with or attached to the sleeves 15 80
and serve to sustain the apparatus. This base
is provided at each side with openings 19
for the inlet and outlet of the air currents,
and these openings are provided with damper
valves 20 arranged to swing on pins 21, 85
which are provided with a suitable means 22
to facilitate the operation of the valves.
Turning freely in the sleeves 15 is a driv-
ing shaft 23 which may be sustained wholly
in said sleeves or in additional supports, if 91
desired. As here shown this shaft is sec-
tional to facilitate assembling the parts. As
shown best in Fig. 3 the shaft 23 has a
rounding part 24 fitting in corresponding
parts 16 of the casing, and encircling -the 95
rounding part 24 of the shaft 23 is a circular
web 25 which may be formed integral with
or attached to said part 24, as desired, and
which is provided with sector-shaped open-
ings 26, one for each of the piston blades. loo
In the form illustrated there are two of
such openings 26. The web 25 is also pro-1,136,976.
