HORACE G. JOHNSTON, OF CORSICANA, TEXAS.
IMPELLER-PUMP.Specification of Letters Patent. Patented Mar. 10, 1914.
Application filed November 19, 1912. Serial No. 732,350.To ati Who fl it may Conecirin
Be it known that I, HoRAcE G. Jon- sTION,
a citizen of the United States, residing at
Corsicana, in the county of Navarro and
G State of Texas, have invented certain new
and useful Improvements in Impeller-
Pumps; and I do hereby declare the follow-
ing to be a full, clear, and exact description
of the invention, such as will enable others
10 skilled in the art to which it appertains to
make and use the same.
This invention relates to impeller pumps
and has for an object to provide a plrnp
embodying a new aid improved form of im-
15 peller.
A further object of the invention is to
provide a pump embodying a self-contained
section having a propeller and coper ting
parts, each section being independent from
20 other sections except in the matter of
driving.
A further object of the invention is to
provide self-contained impeller units being
similar excepting the extreme unit., such
25 units being capable of being connected up
in any desired number.
A further object of the invention is to
provide an improved supporting Iead for
the impeller pump with improved means fcr
30 withdrawing the line of pipe without remiiov-
ing the head.
A further object of the invention is to
provide improved means for connectingir the
several units.
85 A further object of the invention i; to
provide an impoved liner for the units with
improved mea us for retaining such liner
in operalt-i'v s)(-iio.
WiXth these and other objects in view the
40 invention c)mprises certain novel construe-
tions, (omb inations and arrangement of
narts as ill be hereinafter.more fully de-
scribed claimed.

section. fig. 2 is an enlarged diametrical
sectional view of the head. Fig. 3 is a dia-
mct i. C sectional view of one of the units.

impel lets. Fig. G is a view in perspective
of a clutch for operating the igpeller shown

showvllg a slightly different means for at-
tachingthe shafting. Fig. S is a view in
pei-s])ective of a section of shafting and
clutch to cooperate with the clutch member 60
shown at Fig. 7. Fig. 9 is a top plan view
of the follower showing deflecting blades.
Like (haracters of reference designate
correpomdinlg parts throughout the several

The improved impeller pump which
forms the subject matter of this application
comprises a plurality of units shown as a
.whole at 10. The units comprise each a
coupling 11 ;shown in enlaged detail at 7C
Fig. 3 screw threaded at the lower end to
receive the pipe section 12 and provided
above such pipe section with blades 13 form-
11g- a siir having a bearing box 14 cn-
trtlly tireof. The lower end of the bearing 75
b)O\x is provided with a follower 15 which
toge tier with the packing 16 forms a stuff-
iug box for engaging the shaft 17 to prevent
the passage of water and contained matter
about th shaft into the beariii 80
Above the spider an impeller is mounted
comprising a hub 18, one or more fins 19
and a) emuiiracilng and surrounding cylin-
drical band 20. Within the bearing box 14
a wood filler 21 is inserted, the bearing box 85
and wood filler being so proportioned that
the hub 18 of the impeller abuts upon such
wood filter as a thrust-bearing. In practice
it is f1(1nud desirable to employ some exceed-
ingly hard and comparatively non-porous 90
wood such for instance as lignum vitro al-
though the present invention is riot restrict-
ed to the use of such wood.
About the circumferential band 20 of the
impeller a liner 22 is employed such liner- 5
being composed of some flexible or elastic
material such as leather, rubber or the like.
In operation, the cylindrical band 20 woulK
run in comparatively close relation to such
liner 22, a space being shown in the draw- 100
ings simply to indicate that there is oppor-
tunity for movement between the parts.
The liner 22 rests upon an annular shoulder
23 ilk. the coupling 11 with a follower 24
screwed into the end of the coupling 11 to 105
hold such liner in position. Thm' follower 24
is provided with blades 24' radially extend-
ing fronm the periphery but stopping shot
of the hub 18 with their lower ends curved
as indicated at 24' so that the water in it ; 101,090,066.
