the screw threads on the end of such shaft
casing. By means of this nut, the shaft
casing may be adjusted longitudinally, and
the weight of such shaft casing 8 carried
5 from the socket member 14, thus materially
assisting in giving the shaft casing a true
v i a alinement. The packing 26 inter-
po d between the nut 25 and the inwardly
projecting flange 27 on the lower end of the
10 socket portion 14 provides a means for se-
curely packing the joints between the parts
and preventing the access of any moisture to
the interior of the shaft casing. It will be
seen from the foregoing that provision is
15 made for the cooling of the bearing block 9
and the effective oiling of all the bearing
parts both thrust lateral, and that access of
moisture to the shaft and bearing parts is
prevented, and provision at the same time
20 made for the alinement of the shaft casing 8.
Provision is made for oiling the various
bearings .by means of the oil cup 27, and
pipe 28 leading to the top of the bearing
11, which bearing 11 is provided at its
25 upper end with an annular recess 29 for
receiving the oil. Theoil is received in the
recess 29 and gradually finds its way down-
ward along the shaft 1 into the casing
formed by the cap 10 and the socket 14,
30 wherein a bath of oil is provided for the
thrust bearing, and the excess carried
through the pipe 6 to the other bearings
lying along the lengths of the shaft 1. The
pulley 3 constitutes a cap for the oil recess
85 29, and because of its overhang, the support
of the bearing 11 is afforded in substan-
tially the line of stress of the belt acting
over the pulley 3. The pulley is clamped to
the shaft by means of the movable member
40 30, which constitutes half of the hub, and is
fastened to the other half by means of the
transverse bolts 31.
The shafting is guided and supported in-
termediate the bearing block 9 and the bear-
45 ing 32 immediately above the pump by
means of one or more guide members 12.
This guide member is provided intermediate
its ends with a projecting annulus 33 (Fig-
ures 2 and 3), which annulus is threaded
50 and adapted to be engaged by the coupling
member 34. The coupling member 34 thus
performs the function of joining the two
casing sections and holding securely in lon-
gitudinal position the guide member 12.
55 This form of guide member is of cheap con-
struction, and when in position, constitutes
a very rigid and effective guide and support
for the rotating shaft 1, thereby keeping
such shaft properly positioned in the shaft
60 casing. The interior of the guide member
may be lined, if desired, with the Babbitt
metal 35, or any similar composition if de-
sired. The shaft casing 8 is also supported
at proper intervals throughout its lengthby means of spiders 13, which engage such 65
shaft casing and the discharge casing 4.
This spider is shown in detail in Figure 6,
and comprises two hinge members 36 and 37,
the first of which is provided with a pair
of radial arms 38 for engaging the interior 70
of the discharge casing 4, while the other
hinge section 37 is provided with a set screw
38 adapted to engage the discharge casing
4. To position the spider, the hinge mnem-
bers are slipped over the casing 8 and down 75
into the discharge casing 4, after which the
set screw 38 is screwed outwardly until its
head contacts with the inner surface of the
discharge casing and inner surface of the
hinged members 36 and 37 engage and se- 80
curely hold the shaft casing 8, the operation
of the single member 38 accomplishing these
two results.
Having thus described my invention and
illustrated its use, what I claim as new and 85
desire to-secure by Letters Patent is the fol-
lowing:-
1. In combination with a centrifugal
pump having inner and outer casing mem-
bers, a discharge casing secured to and sup- 90
porting the outer casing member, a laterally
opening outlet casing thereon provided with
a supporting socket, a shaft casing coupled
to the socket portion and to the inner casing
member, a drive shaft having a thrust bear- 95
ing in the socket and extending through the
shaft casing to the pump, and means for
supporting the outlet casing.
2. In combination with a centrifugal
pump having inner and outer casing mem- 100
bers, a discharge casing secured to and sup-
porting the outer casing member, a laterally
opening outlet casing thereon provided with
a supporting socket, a shaft casing coupled
to the inner casing member and having an 105
adjustable connection with the socket, a
drive shaft having a thrust bearing in the
socket and extending through the shaft cas-
ing to the pump, and means for supporting
the outlet casing. 110
3. In combination with a centrifugal
pump having inner and outer casing mem-
bers, a laterally opening outlet casing pro-
vided with a supporting socket, a discharge
casing secured to the outlet casing and to the 115
outer casing member, a shaft casing coupled
to the supporting socket and to the inner
casing member, a drive shaft having a thrust
bearing in the socket and extending through
the shaft casing to the pump, and means 120
for supporting the outlet casing.
4. In combination, a discharge casing, a
laterally opening outlet casing thereon pro-
vided with a downwardly extending socket
portion provided with an inwardly extend- 125
ing flange at its lower end, a shaft casing
extending through the flange and threaded
at its upper end, a nut engaging the thread2
