said turbine extending at least through the
compartment having the liquid inlet therein
and means associated therewith for directing
the cleaning liquid from the first-mentioned
compartment to the area within the casing
occupied by the turbine;
c. means for releasably receiving the cas
ing hub in the other compartment; and
d. an outlet opening for discharging the
cleaning liquid from said other
compartment.
According to another aspect of the invention there is provided a method of cleaning automotive torque converters in which the torque converter is provided with a leak-proof liquidholding casing element having a single opening therein and an outwardly extending hollow hub surrounding said opening and attached to the outer surface of the casing for supporting said casing, and an independently operatable turbine element positioned within said casing, the method comprising directing a cleaning liquid into the casing in the vicinity of the turbine, mechanically and positively rotating said turbine to swish the cleaning liquid about the turbine and the inner surface of the casing, and exhausting the cleaning liquid from the casing through the previously mentioned opening in the casing and the hollow casing hub.
Referring to the drawings which illustrate one embodiment of the invention, and in which like reference characters denote like and similar parts throughout the several views:
Figure 1 is a view in perspective of the apparatus illustrating the manner in which the apparatus is used.
Figure 2 is a diagrammatical view partly in section and partly in elevation, showing the various elements of the apparatus in working relationship.
Figure 3 is a perspective view in elevation of the liquid directing unit.
Figure 4 is a vertical sectional view of the liquid directing unit shown in Figure 1.
Figure 5 is a top plan view of the liquid directing unit.
Figure 6 is a bottom view of the same.
Figure 7 is an enlarged sectional view taken along a plane bisecting the longitudinal axis of the turbine hub.
Referring to the drawings there is provided a table 1 having supporting legs 1' on which the apparatus is supported.
The table is provided with an opening in which a reservoir, or tank, 2 is supported.
Within the reservoir or tank 2 is placed a predetermined amount of cleaning fluid, or solvent 4. However, the reservoir, or tank may be supported independently by any suitable means. Extending upwardly from the upper surface of the table 1 is a post 6 having a horizontal arm 8. Supported upon the post 6 is a suitable electrically operated motor 10 having a rotatable shaft 12 extending outwardly from each end of the motor. On one end of the shaft 12 is a pulley 14. The pulley is adapted to operate a shaft 16 through a suitable drive means, such as a belt 18 and pulley 22, fixed to the upper end of the shaft 16. The shaft 16 is rotatably supported by a bearing (not shown) carried by the arm 8. Affixed to the opposite end of the shaft 16 is one end of a coupling unit 24 which is vertically slideable on the shaft 16.In order to fix the location of the slideable coupling unit 24 relative to the shaft
16 there is provided a rotatable thumb screw 27 threadably attached to the shaft 16 which
operates within a slot 24' in the coupling unit.
The opposite end of the coupling member 24 is provided with a slot 24" for detachably receiving a pin 25 fixed to the upper outer end of a rotating spindle 28. The spindle 28 is a part of a liquid directing unit A and is of such length and form as to extend into a torque converter unit B and engage the central bore
31' of the turbine 31 of the unit B. In use, the torque converter is placed on the table 1 below
the liquid directing unit A as shown in Figures
1 and 2. The casing 29 of the torque converter
is shown supported on suitable members 26 to hold it against rotation.
On the opposite end of the motor 10 there is mounted a housing 10' adapted to support a liquid pressure pump 7 having a conduit 17 leading from a filter 11 to the intake opening
of the pump 7 and a conduit 19 leading from
the pump outlet to the liquid directing unit
A. The filter 11 is supplied with the cleaning
liquid, or solvent, by the conduit 21.
The liquid directing unit A is divided into
upper and lower compartments 36 and 38
respectively having fluid-tight bearings 32 and
34 in which the turbine driving spindle 28 is
rotated. The spindle 28 is adjustable to a
limited degree axially of the unit A for adjust
ing the spindle 28 to different sizes and types
of torque converters. The compartment 36 is
provided with an opening 40 adapted to, receive
a fixture 42 for receiving one end of the clean
ing liquid supply conduit 19. The spindle 28
is provided with a central opening 28', as
shown in Figure 4. At the upper end of the
central opening 28' is an aperture 44 to admit the cleaning liquid to the opening 28' in the
spindle ta be fed to the central opening 31' of
the turbine 31.The vertical adjustment of the
spindle 28 is never greater than the distance
between the bearings 32 and 34 in order to
keep the aperture 44 always positioned within the upper compartment 36.
The lower end 30' of the liquid directing
unit A forming the second compartment 38 is
in the form of an inverted cup and is ef such
diameter as to receive the hollow hub 29' of
the casmg 29. Secured to the inner surface of
the cup-shaped portion 30' is an apertured
flexible collar 46 surrounding the spindle 28
and which is stretchable to engage the outer
surface of the hollow hub 29' to prevent leak
age of the liquid being forced out of the second
compartment 38.
The second compartment 38 is also provided
with an opening 50 for receiving a fitting 52
adapted to receive one end of a hose 51 leading
back to the reservoir 2 for discharging the
liquid cleaning fluid after it has passed through
the torque converter.
Referring in particular to the turbine 31
which rotates within the casing 29, the central
opening 31' of the turbine Is provided with a
bore having grooves 60 about its inner surface
to receive a splined drive shaft. These bores
come in slightly different sizes to accommcdate different size drive shafts; therefore, the lower
end of the spindle 28 is provided with a
tapered end portion 28" adapted to engage
various size turbine bores. The smaller end
28"' of the taper extending outwardly from
the spindle is of such size that it will fit
practically all size bores carried by different
turbines.Extending outwardly along the sur
face of the tapered portion 28", and affixed
thereto, is a single rib or spline 39 which is in
a plane with the axis of the spindle member
28 in order to engage one of the grooves formed
on the inner surface of the bore in the turbine
for rotating the same.
In the cleaning operation of the present
apparatus the casing is held in a stationary
position while the turbine is rotated relative
thereto
The cleaning liquid, or solvent 4 is intro
duced into the upper section of the torque con
verter B through the aperture 44 by way of the
hollow spindle 28 leading to the turbine 31, for
removing undesirable substances and particles
that are in the converter, after which the cleaning liquid is forced out of the torque converter by way of the hollow hub 29' of the casing 29 through the second compartment 38
to the opening 50 and the conduit 51 to the reservoir 2. At the same time, the cleaning liquid from the reservoir 2 is being picked up by the pump 7 by means of the conduit 21 and after passing through a filter 11 may be recycled through the conduits 17 and 19 to the torque converter. By using this method of directing the cleaning fluid, cr solvent, through the torque converter it is not necessary to puncture the converter casing to allow the cleaning fluid, or solvent, to be drained from the converter casing.
However, the method depicted is not necessarily limited to the present apparatus; for example, the method could involve introducing a cleaning liquid within the casing and rotating either the turbine element while the casing element is held in a stationary position, or both elements may be rotated in opposite directions or in the same direction at the same or different speeds to obtain a swishing action within the casing and draining the cleaning liquid from the casing through the hollow hub of the casing.
