rotary movement impinges against the con-
vex sides of said blades.
The follower 24 is screw threaded to re-
ceive the lower end 25 of the pipe so that
5 when the impeller, unit is in -position in a
line of pipe the parts are associated as shown
it Fig. 3. The impeller unit, however, con-
sists of the coupling, the spider, the pro-
peller and the shaft and pipe connected at
10 the bottom of the coupling. The shaft from
above is connected with the hub of the im-
pcl is in such manner as to insure rotation.
of the. inipller with the shaft but to per-
mit l'negitudinal sliding movement. As
15 shown at Fig. 3 the shaft 17 is provided with
a key 96 whereby the shaft is splined into
the hub. shown at Figs. 5 and 6 the hub
i> provided with a diametrical slot 27 and
the shaft 17 is provided with a collar 28
20 rigidly secured thereto having wings 29
-proportioned to fit into the slot 27 with the
extremity 17' serving as a guide to enter'
" first the central bore 30 of the hub.
Instead of em ployinmg a hub and clutch
25 such as shown att Figs. 5 and 6, however,
the ordinary dental clutch may. be employed
as shown at Figs. 7 adl 8, the collar 31 be-
ing provided with lugs 32 complementary to
the lugs 33 carried upon the impeller hub
30 18, the eaxtremity 17' of the shaft serving
as asuide as above described relatively to
Figs.' and 6.
Below the lower unit 10 . any sort of
strainer extremity, as indicated convention-
35 ally at 34 and pipe section 35 in Fig. 1, may
be employee and the top unit is provided
with a pipe section 36 which connects such
top unit with the head shown at detail in
Fig.2. Such head comprises a base '37 which
40 is rigidly and permanently secured to the
well or other covering indicated at 3S andi
is annular in form aring a flange 39 with
central opening through which the top)
section of the pipe 36 is inserted. The top
45 section of pipe is provided with a threaded
collar 40 having a flange 41 proportioned to
bear upon ,the -Annular' flaiige 39 'with a
gasket 42 introduced between the flange to
produce a water-tight Joint. bovethe base
50 37 a housinggX13 is erected having a discharge
connection 44 and a coer member 45. The
cover member 45 is provided with a bearing
46 through which the shaft 17 extends with
a stuffing box 47 provided to produce a water-
55 tight Joint. Upon the upper end of the shaft
17 a pulley 408 is employed by which power
is transimittel to the shaft 17 and the several
units connected therewith below the head.
To remove the connected units it will not be
60 necessary, therefore. to remove the entire
head but the cover member 45 is removed
by the removal of the bolt- 49 and the re-
r!mov l Ci such cover carries with it the top
i 1i oise rt soehour ienth of
0. pipe is n0w inserhed inro the liousing' andinserted into the threaded ring 40, such .
length of pipe extending. above the housing
in position to engage the grappling and
lifting appliances. The connected units are
lifted by such lifting device until th first 73
unit is above the housing whereupon it is un-
screwed and removed and the lifting process
continued until all of the units have been're-
moved from the housing.
To secure access to thestuffing box 47 a
cover 50 is secured upon the housing in the
usual well known manner.
About the bearing 46 a boss 51 is provided
producing a chamber 52 between such boss
and bearing-box, the walls of the boss being 33
higher than the top of the bearing box so that
oil contained within the chamber 52 is in po-
sition to lubricate the bearing. To supply
lubricant .to tpe chamber 52 the cover 45 is
provided with a passage 53 .which extends 85
from tlieperiphery of such cover to the bear-
ing 46 with a lateral>54 leading to the cham-
ber 52. Any convenient way of supplying oil
to the passage 53 may be. employed, here
shown conventionally as a pipe 55 and oil o
cup 56. It will be apparent that even when
the oil in the chamber 52 is lower than the
top of the bearing 46 oil will still feed
through the lateral 54 and the passage 53
into the bearing.'95
In operation the head will be located over
the pumping position, the cover 45 removed
and units coupled/ together and '-inserted
through such housing until the lower unit
has been inserted a sufficient and desired ioo
distance into the water when the cover will
be placed in position with, the top shaft sec-
tion engagiing the first unit and the power
applied whi ch will, as will be apparent, ro-
tate the impellers in all of'the several units 105
forcing water upwardly, as indicated bythe
several arrows, the spider. blades 13 and 24'
serving to prevent undue rotation of the
water within the pipe and presenting the
water to each impeller moving substantially 1ie
longitudinally of the pipe until discharged.
It will be apparent also thatthe members of
each unit will 'be carried and supported
wholly upon the coupling of that particular
unit so that the shaft section connected with 115
the pulley. 48 is not required to support the
entire line of shaft with its associated im-
pellers as is done in ordinary impeller pump
construction. 'It will be apparent also that
the several units are wholly interchange- '120
able ind that more or less units may be added
or taken away as circumstances may require
by the simpleprocess of removing a umit or
removing the top pipe section 36 and add-
ing a unit. . - 125
I claim:
1. In a pump, a unit comprising a coi-
pling, a spider within the coupling, an ime
seller mounted to rotate upon the spider.
a liner rigidly' connected with the walls of 10dM
