14 Claims. (01. 230-253)
This invention relates to a fan unit and more
particularly to a portable multiple fan unit in
which ?uid motor fans of the propeller type are
mounted in a novel manner upon a supporting
base.
In the drilling of oil wells in insect infested
areas it is desirable, if not necessary, to provide
portable fans that will serve the dual function of
cooling the operators and blowing insects from
by means of upright'members l3, i4, and 15.
The respective members of the frame I are se- 10
cured into a composite unit by any suitable means
Fluid under pressure is
connected to the common source of energy and
15 separately adjustable to direct air streams to any
desired point or points on the derrick platform.
It is therefore an object of the invention to
provide a fan unit in which ?uid actuated fans
may be independently directed as desired about
the derrick platform without in any way affect
ing their efficiency of operation.
A further object is to provide a multiple fan
unit adapted to deliver a stream of air toward
30
40
shaft and within the fan shield 4 may be directed I
to send an air stream upon any desired object.
A frame 1 comprises base members or skids 10
which are secured to support members II and I2
the zones of operations.
available at the drilling rig and it is highly desir
able that the fans used be provided with ?uid
actuated motors and that a plurality of fans be

in Figs. 1 and 2 as comprising a frame or base I,
upon which is mounted fan units 2 and 3, each
of which is swivelly mounted upon the base I
so that the impeller mounted upon the motor
any particular object or objects.
A still further object is to provide a multiple
fan unit embodying a frame upon which ?uid
actuated fans are independently mounted in a
novel manner so that the air stream from the
respective fans may be directed upon any desired
object.
‘
Another object is to provide a fluid actuated
fan which is swivelly mounted upon a support
with the intake and exhaust lines to the ?uid
motor coaxial with the axis of rotation of the
motor upon its support.
Still another object is the provision of a ?uid
actuated fan, which is pivotally mounted upon its
support, the intake and exhaust ports of the ?uid
motor being coaxial with the pivoting axis.
Other objects, together with the foregoing, will
be apparent from the following description taken
in connection with the drawings, in which:
Fig. 1 is an elevational view of a fan unit em
bodying the invention.
Fig. 2 is a plan view of the unit shown in Fig. 1
showing the fans adjusted to direct air streams
in divergent directions.
as by welding or bolts.
‘
‘
Each of the fans 2 and 3 comprises a ?uid
motor 16 rotatably supported upon the frame
work formed by members H and I2 about a ver- 15
tical axis in a manner that will be later described.
The casing of each of the ?uid motors 2 and 3
serves as a support for protective shield 4 within
which rotates the propeller driven by the motor.
Inlet and exhaust pipes 20 and 2! for each of ‘210
the fluid motors extend outwardly from the casing
and are in line with the axis of rotation of the
motor upon its support. Inlet pipes 20 are con
nected to an inlet manifold 22 through unions 23
while outlet or exhaust pipes 2| are similarly c‘on- 25
nected through unions 24 to an exhaust mani
fold I9.
(
‘
From this brief description of the fan unit of
the invention it may be seen that the invention
provides a portable fan unit having a plurality 30
of fans that may be directed upon single objects,
or the fans may be each directed upon a sepa
rate object, and that the construction is such that
no material alterations of the ?uid pressure lines
need be made in order to direct the respective fans
as desired. The speci?c construction whereby the
desired objectives are obtained will now be de
scribed.

As best illustrated in Fig.’ 4, the supporting
framework is provided at opposite ends with a 40
downwardly extending bearing member 25, which
may be integral with the supporting structure.
Flanges 25 on the bearing member 25 are adapted
to engage portions of the supporting framework
so that the bearing member may be secured there- 45 _
to in any suitable manner. At the same time
Fig. 3 1s a sectional view through one of the
?uid motors of the invention.
Fig. 4 is a sectional View through the ?uid
?anges 25 are provided with an upwardly facing
surface 21', adapted to cooperate with a comple
mental face 28 on the motor casing 29.
Bearing member 25 is provided with a central 50
motor taken at right angles to that shown in
Fig. 3.
secured to the face 28 on the motor casing 29.

The fan unit comprising the invention is shown
55
bore 35, enlarged at 3! to receive ?anged boss 32,
The enlarged portion 3| of the bore 36 provides
an annular space for receiving the ?ange 33 of
boss 32 and the heads of cap screws 3A, which 55

The lower
or exhaust manifold 22 or l9, and the ?ow con
portion of bearing member 25 is provided with
_ne~ction between parts is completed by tightening
outwardly extending ear 35, which is slotted ra
dially of the bearing member and a bolt 36 passes
transversely through the slotted ear. The adja

cent bore of the bearing member 25 is of such
diameter that boss 32 may be locked therein by
through manifold 22 to the nozzle 15, which di
,rects ?ow upon the buckets of runner 50 where
tightening bolt 36. On the other hand, by loosen
ing this bolt this boss 32 and the motor casing
10 connected thereto may be freely rotated about
the axis of the bore 30.
Fluid motor I6 of the present invention has a
circular casing 29 comprising complemental sec
tions 4!] and 4|, which, as shown in Fig. 5, have
15 annular insert shoulders 42 so that when in as
sembled relation the complemental parts are in
accurate mating relation. Sections 40 and 4|
are held securely in this mating relation to form
a composite casing 29 by means of transverse
20 bolts 43.
Each of the sections 40 and 4| ?ares outwardly
from a medial line through the casing and has
a ?ange 44 at its outer end. An inwardly con
verging wall 45 on each of the casing sections
provides in the composite casing a chamber in
2,5 which
the motor runner is adapted to rotate.
Intermediate wall 45 and ?ange 44 is a trans
verse wall 46 provided with central openings 41
to receive anti-friction bearings 48 in which the
.30 shaft 49 is adapted to rotate. Runner 5!) is
?xed upon shaft 49 and comprises a hub 5! and
a radial ?ange 52 which supports buckets 53
thereon.
.
A suitable fluid seal 54 is provided between
35 hub 55 and the inner ?anged ends 55 of Walls
45. This seal serves to prevent leakage of the
operating ?uid from within the runner chamber
to the chamber formed by walls 45 and trans
verse Walls 46.
C‘ap plates 55 and GI are secured to ?anges 44
by means of cap screws 62, the latter of these
plates having a central opening 63 to pass an
extension 54 on shaft 49 for mounting of the
fan propeller within the fan shield 4.
An opening 15 at the top of the motor casing
29 is provided with a closure member 1i se
cured thereto by cap screws 12. This closure
member ‘H has a threaded opening 13 coaxial
With the bore in boss 32 and leading into- a pas
50 sageway 74 in nozzle 15, which is made integral
with the closure member TI. The runner 50 is
driven by an actuating ?uid such as steam, or
other ?uid under pressure, by being directed
through the nozzle 15 whence it impinges up
55 on the buckets 53 on runner 50. A portion of
the energy of the ?uid is thus converted into
mechanical
energy.
In order to
abstract a
greater portion of the energy from the actuating
?uid, a ?uid guiding unit 11 is attached to the
60 side wall of the casing 29 and is adapted to re
direct the ?uid through buckets 53 before the
?uid is exhausted into the annular space 78 about
the runner. The cylindrical bore 3'! in boss 32
provides a passageway from the annular space
65 18 within the motor casing 29 and hence serves
as an exhaust port for the actuating ?uid from
which energy has been abstracted during pas
sage through the runner 50.
Inlet and outlet pipes 2!] and 2!, respectively,
70 are coaxial and are threadably secured in clo
sure member ii and in boss 32 respectively.
One end 82 of the nut unions 23 and 24 is thread
ably secured to the outwardly extending ends
of the pipes 20 and 2|. The other end of each
75 of these unions is attached to an end of the inlet
In the operation of the ‘device just described
steam or other actuating ?uid is introduced
byv rotation is imparted thereto. After passing
through the buckets 53 the actuating ?uid is de
?ected in the guiding unit TI and thence passes 10
outwardly through buckets 53 and into the an
nular space 18. The exhaust ?uid passes from
the annular space 18 within the casing 19
through the exhaust manifold l9. The respec
tive motors are thus actuated to drive the im 15
pellers within their respective shields 4 whereby
the desired‘ functioning of the device accrues.
Valves iii are provided in the ?uid passageways
whereby either of the fans of the unit may be op~
erated independently or the fans may be op 20
erated simultaneously and at different speeds.
Attention is also directed to the fact that with
the described construction the exhausted ?uid
leaves the motor casing 29 at the lower end
thereof whereby any condensate from the ac 25
tuating ?uid is immediately removed from with
in the motor casing.
If it is desired to alter the position of either
of the fans of the unit the nuts upon unions 23
and 24 are loosened, together with bolt 36 in 30
bearing member 25, whereupon the motor and its
associated fan may be rotated about an axis that
is common to the bearing member 25, pipes 20
and 2| and unions 23 and 24. When the desired
position of the ?uid motor is obtained it is then 35
only necessary to tighten the unions and bolt 36
to again place the fan in operation.
From the foregoing description of the con
struction and mode of operation of the device of
the invention it is believed apparent that the 40
indicated objects of the invention are realized.
While the speci?c embodiment has been dis
closed, it is to be understood that various changes
may be resorted to without departing from the
spirit of the invention and it is desired that the 45
disclosure be construed as illustrative only, the
invention being limited only in scope by the ap
pended claims as viewed in the light of the
