Description
(54) MIXER FOR LIQUID CHARGES
(71) I, LESLIE HOLMES GARLINGHOUSE, a citizen of the United States of America, whose post office address is 2415 East
Washington, Los Angeles, California 90021, United States of America do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement: The present invention relates to a mixer and particularly to the application of the wobble principle as applied to a flexible mixing container.
Although the wobble principle has been made use of in mixing such ingredients as concrete, such mixers are not always capable of being effectively and economically produced in small sizes such, for example, as might be useful in mixing laboratory samples or in another field in the washing of clothes. For more sophisticated mixing of many of the more recent plastic materials, some loaded with fillers, and with various rapid set up times, aided by heat and catalysts, slow motion but rapidly effective mixing techniques need to be made use of. There is further, in sundry industrial processes, need for a washing machine capable of washing both hard and soft objects where the washing takes place in presence of liquid, liquid detergent, or other washing media, and for the washing of various materials, both hard objects and soft objects such as fabric.
It is also necessary in some types of laboratory conditioning operations to wash or agitate a liquid in the presence of a vacuum, in the presence of a pressure above atmospheric, and perhaps in other assorted special environments.
The present invention provides a method of using a mixer for a charge of predetermined volume of a liquid-like consistency, said mixer comprising a frame, a composite container means on the frame for said charge comprising a lower flexible section with a lower chamber and having an upper perimetrical edge, an upper rigid section with an upper chamber of fixed volume having a rigid cylindrical wall with a lower perimetrical edge, and an attachment joining said lower and upper sections together at said edges: a wobble plate mounted on the bottom of the flexible section; a wobble drive rotatably journaled in a lower portion of said frame and having a driving relationship with said wobble plate; a motor on said frame at a location below and exterior relative to said container means; said motor having a single direction driving connection with the wobble drive whereby to impart an oscillatory motion to the flexible section and the charge, a connection between the upper rigid section and the frame, the connection being at a location spaced from the lower perimetrical edge, comprising the steps of arranging the volume of the charge to be greater than the volume of the lower chamber, and the aggregate volumes of the chambers respectively in the lower and upper sections being arranged to provide a liquid level intermediate upper and lower ends of the upper rigid section, and permitting the charge to shift cyclically between said chambers during an operation in response to action of said wobble plate.
The features and objects of the present invention will be best understood from the following description of the accompanying drawings, in which:
FIGURE 1 is a longitudinal sectional view of one form of the device set up and ready for operation;
FIGURE 2 is a cross-sectional view on the line 2-2 of Figure 1;
FIGURE 3 is a longitudinal sectional view of another form of the device showing a liquid-like charge of material in the inner moving container preparatory to the conditioning operation;
FIGURE 4 is a longitudinal sectional view of a somewhat simpler version of the device shown in Figure 3; and
FIGURE 5 is a longitudinal sectional view of still another form of the invention.
In one of a variety of forms of the invention chosen for the purpose of illus tration, there is shown in Figure 1 a frame indicated generally by the reference character 10 consisting of a base 11 and upright legs 12 and 13 stiffened by braces 14 and 15 respectively. A yoke 16 consisting of a platform 17 and arms 18 and 19 is tiltably supported on the legs 12 and 13 by employment of a pivot connection 20 for the arm 18 and a pivot connection 21 for the arm 19. A handle 22 may be employed tcl tilt the yoke and its load, when desired.
Supported by the yoke on the platform 17 is a housing 25 having a bottom wall 26 and a side wall 27, the side wall partially defining a chamber 28.
At the upper end of the housing 25 is a section 27' joined to the housing 25 by a flexible band 29. The section 27' is attached to an annular band 30 on which are lugs 30' by which the section 27' is supported at the tops of the arms 18 and 19. Also supported by the annular band 30 is an agitating container indicated generally by the reference character 31.
It is of material significance that the container be a two-part construction, which consists of two sections, namely an upper rigid section 32 and a lower flexible section 33.
In the form of the invention of Figure
1 as in the other forms of the invention
the object is to mix, wash or otherwise condition a specific charge of material in batch lots. Although the volume of the charge may vary to some extent, there is a relationship to the volume of the container which should be observed. Obviously
the aggregate volume of the upper rigid section and the lower flexible section must
exceed the volume of the charge. Of greater importance is that the volume of
the charge be in excess of the volume of the lower flexible section. This means that
the volume of the upper rigid section be
at least comparable to that of the lower
flexible section though preferably greater
by a measurable amount.
Where the upper rigid section has a
cylindrical form and the lower flexible section is connected directly to it and has at that point substantially the same cylindrical
form, the depth of the upper rigid section will be materially greater than the depth
of the lower flexible section.
With the relationship as described, the charge will occupy both sections, and experience a different mixing effect in each,
portions of the charge passing cyclically
out of one section and into the other and then returning. By having a substantial
portion of the charge in the upper rigid
section at all times, the lower flexible
section will be required to move only a
smaller fraction of the charge during its cyclical wobble operation while portions of the charge merely change places in the container as a whole. The result is a more thorough, more rapid mixing or washing operation, as the case may be, without, however, requiring any more appreciable speed up in the oscillatory wobble motion.
In the embodiment of Figure 1 the liquid level of the charge will normally be somewhere near the mid portion of the upper rigid section. If a fold-in type of mixing is to be done, as where solid ingredients are to be mixed with a liqiud mass, the level may be below the free end of such agtator post 46 as may be employed. For washing operations the upper rigid section may be almost full.
In the exemplary embdiment of the invention of Figure 1, the upper edge of the lower flexible section is anchored to the lower edge of the upper rigid section by a band 34. A cover 35 provided with a handle 36 is shown and there may be provided a seal 37 which makes a sealing connection with an upper rim 38 of the rigid section 32.
Fastened to the bottom of the lower flexible section is a wobble assembly indicated generally by the reference character 39. The wobble assembly consists of an inner plate 40 and an outer plate 41, outer perimeters of which secure between them an annular edge 42 of the lower flexible section by means of bolts 43. To give the charge an adequate lift when the wobble plate 40 is oscillated, it is advisable to have the diameter of the wobble plate relatively large as compared to the diameter of the lower flexible section measured, for example, at the upper perimetrical edge.
An electric motor 50 is hung on the under side of the platform 17 and connected thereto by a casing 51 housing a gear reducer. A drive shaft 52 from the gear reducer extends upwardly through a hole 53 into the chamber 28. A liquid-tight packing 54 forms a seal, being held down by a flange 55 secured by screws 56.
On the upper end of the drive shaft 52 is a fitting 57 providing an offset head 58.
A tilted shaft 59 extending obliquely upwardly from the offset head is rotatably contained in a disc 45 which is anchored to the inner plate 40.
An agitator post 46 secured to the inner plate 40 by a bolt 47 extends into the interior of the container 31 and moves with the wobble assembly 39. A relatively short post is shown. Occasions may, however, be such as to require a much longer post extending well into the upper rigid section.
By rotation of the fitting 57 and offset head 58 at a relatively slow speed achieved by employment of the gear reducer, an oscillating movement or wobble motion is imparted to the disc 45 and, accordingly, to the bottom of the lower flexible section 33 and its contents. Oscillation as described provides the agitation for the conditioning, cleaning or mixing of a charge in the container 31.
Where some special condition is desired as, for example, conditioning in the presence of a vacuum, there may be provided a vacuum line 60 in communication with the chamber 28 in the housing 25. A vent 61 protected by a baffle 62 is in communication with the interior of the container 31 to equalize pressure between the exterior and the interior of the flexible section 33 thereby permitting it to operate freely as long as the containers are being subjected to a vacuum condition. Conversely, a pressure condition could be maintained through the same line 60.
After conditioning of the charge within the container 31 by the wobble motion described, the charge can be discharged after first removing the cover 35 by manipulating the handle 22 in order to tilt the yoke and consequently the container 31 to a partially inverted position whereby the contents can be discharged. In this tilting operation the entire apparatus, namely the yoke, the container 31, and motor 50 is tilted about the axis of rotation of the pivot connections, 20 and 21.
By so balancing the assembly that the greater load is on the side occupied by the electric motor 50, when the container 31 is loaded with a charge, the yoke will always tend to assume the position of
Figure 1 which may be designated as upright position with the cover 35 at the top.
In a second embodiment of the invention shown in Figure 3, the frame consists of a cylindrical base 65 in which a chamber 66 houses an electric motor 67 with its gear reducer 68 arranged to drive a
drive shaft 69. A conical clutch 70 when in engagement transfers the drive to a
driven shaft 71 which extends through the bottom 72 of a housing indicated generally by the reference character 73 embodied in part in a cylindrical wall 74. A thrust ring
75 attached, via a seal 76', to the bottom
72 above an opening 76 therein accom
odates the driven shaft permitting it to
rotate freely. At the upper end of the
driven shaft is a fitting 77 having an off
set head 78 on which is a tilted shaft 79
forming part of the wobble action. The
tilted shaft 79 is rotatably secured in a
disc 80 which is part of an inner plate 81.
The inner plate 81 and an outer plate 82
hold between them an annular edge 83 5 of a flexible section 84, the flexible sectic
being part of a container indicated gener
ally by the reference character 85, of which
a rigid section 86 forms the other part.
The upper edge of the flexible section is
anchored to the lower edge of the rigid
section by means of a band 87.
For mounting the container in the hous
ing 73 there is provided a partition 88 on
which is an annular flange 89, the rigid
section 86 being secured to the annular
flange 89 by welding or other appropriate
attachment.
In addition to providing a support for
the container 85, the partition 88 divides
the interior of the housing 73 into an
upper chamber 90 and a lower chamber
91. The container 85 is in communication
with the upper chamber 90 not only by
reason of the rigid section having an open
top, but also by use of the multiplicity of
perforations 92 which extend through the
wall of the rigid section. If desired the
flexible section 84 may be provided with
perforations 184 to communicate with the
lower chamber 91. A solenoid actuated
drain valve 93 is adapted to be opened and
closed by remote control when the liquid
contents of the container are to be dis
charged. After the liquid contents pass
through the open drain valve into the
lower chamber 91, they can be discharged
therefrom by a discharge valve 94.
As pictured by way of example, the
machine is set up for washing a charge
consisting of bundles 98 of fabric in a
detergent liquid 97. It will be appreciated,
however, that this is by way of example
only inasmuch as the charge be solid ob
jects or virtually any type or description
of article which might need conditioning,
as for example, washing, dyeing, impreg
nating, bleaching, softening, etc. Here the
volume of the charge is about twice the
volume of the lower flexible section, and
the liquid level is near the top of the
upper rigid section.
A lid 99 is shown closing the top of the
housing 73 where an occasion might re
quire conditioning under special desig
nated pressure as, for example, either a
vacuum or negative pressure on the one
hand, or a positive pressure on the other
hand. On other occasions the chamber
90 may be filled with a selected gas of
some predetermined mixture.
After the charge has been conditioned,
as suggested in the foregoing description,
and it should become desirable to rid the
bundles 98 of surplus moisture, there is
an arrangement built into the housing 73
making it possible to spin dry the contents.
To accomplish this an annular bearing com
prising upper and lower races 103 and 104
serves to mount the housing 73 on the ncylindrical base 65. A gear train consisting of a large gear 105 on the drive shaft 69 meshing with a small gear 106 on a driven shaft 107 is made use of to rotate the driven shaft 107 at a relatively higher speed. The driven shaft is journaled on a bracket 108.
A second drive shaft 109 in axial alignment with the driven shaft 107 has a magnetic clutch 110 associated therewith the second drive shaft being rotatably mounted in a bracket 111. On the second drive shaft 109 is a pulley 112 over which passes a belt 113, the belt passing over a pulley 114 on the drive shaft 71. The pulley 114 is made fast to the bottom 72 of the housing 73 so that when the pulley 114 is rotated, the housing 73 will be rotated. When the housing 73 is being rotated at the higher speed made possible by the gear ratios of the gears 105 and 106, the clutch 70 is disengaged by manipulation of the plunger
115 and rocker arm 116 in a substantially conventional fashion.
Holes 88' through the partition 88 allow liquid to entirely surround both upper and lower portions of the container 85. A seal 76' effectively seals the opening 76 through which the drive shaft 71 passes. In the form of invention of Figure 4 which resembles Figure 3 as to its general aspects, a partition 188 which carries the upper rigid section 86 of a container 85' of a container 85' on the cylindrical wall 74 is imperforate. Holes 184 through the lower flexible section 84' permit liquid to pass frelly between the interior of container 85' and the lower chamber 91. A housing
118 contains a fixed outer bearing ring
119 and an inner bearinng ring 119' attached to the upper rigid section 86 so that if need be the container 85' is free to rotate. Adischarge valve 94' drains the upper chamber 90.
In the form of invention of Figure 5, spin dry is accomplished in a different fashion. To make this possible an annular bearing 120 is made use of. One bearing ring 121 is mounted on a partition 122, and a second bearing ring 123 is secured to a bushing 124 anchored in a platform 125. The partition 122 is at the top of a base 126 on a supporting surface 127.
More particularly the partition is the bottom of a housing 128, the housing forming a chamber 129 for a reservoir of liquid 130.
Within the chamber 129 is an agitating container indicated generally by the reference charcter 131. In this form of the invention the agitating container 131 has a rigid upper section 132 and a flexible lower section 133 secured to the upper section by a band 134. A rotating yoke 135, of which the platform 125 is part, has arms 136 and 137, the tops of which have plates 138 and 139 to which the upper section 132 is anchored. Perforations 140 allow the liquid 130 to pass into the container 131 and a lid 141 keeps the liquid from splashing out.
At the bottom of the lower section a solenoid actuated discharge valve 143 can be opened to comple tely drain the container when needed. To empty the chamber 129 a drain valve 146 is provided.
For agitating the contents 147 of the container 131 while the yoke 135 remains stationary, use is made of a wobble assembly 150. As in other forms of the invention, the wobble assembly consists of an inner plate 151 and an outer plate 152 which clamp between them an annular edge 153 of the lower section.
Power for the operation is provided by a motor 155 in the base 126 acting through a speed reducer 156 to rotate a motor shaft 157. A fitting 158 on the shaft 157 has an offset head 159 on which is a freely rotating shaft 160 journaled in a disc 161, the disc being part of the inner plate 151.
A bearing unit 162 secured by a flange 163 to the underside of the partition 122 contains a bearing 164 which rotatably supports the shaft 157, the shaft extending through an opening 165 in which is a seal 166.
Where a spin dry action is desired, there is employed a clutch 170 of substantially conventional construction mounted in the bushing 124, and, when desired, operated by electronic means (not shown) from an exterior station. Action of the clutch is to interconnect the shaft 157 and the yoke
135 so that the yoke and all that is mounted on it rotates.
In this form of the device perforations 168 may be provided in the flexible lower section 133.
The motor 155 may, for example, be a two-speed motor controlled by an appropriate motor switch 171 whereby when the device is being used for conditioning such, for example, as washing, the low speed rate is employed. When the spin dry operation is to take place, the motor can be shifted to high speed operation.
Consequently, the rotation of the yoke 135 at the relatively higher speed spins the container 131 thereby to rid the bundles of presence of liquid by operation of centrifugal force. Such liquid as may be thus spun from the bundles can again be drained off through the drain valve 146.
