'12 Claims. (01. 100-50) This invention relates to a new and improved i extractor for washing machines.
The usual method of extracting liquid from clothes after they have been washed is either by the use of a wringer in which the clothes are passed between pressure rolls, or by theuse of a revolving basket or centrifugal extractor. 'l
The disadvantage of a wringer consists in the fact that it frequently injures theclothes and 10 tears oii. buttons, hooks and eyes.
There is also the objection that it requires power to operate and further, there is the liability that the operator's hand ;may become caught between the rolls.
Although a centrifugal extractor is a highl eiiective drier, the basket requires high speed rotation and mechanism must be provided for the operation.
purpose whichis independent from the washing machine driving mechanism, although certain interconnection may exist.
Further, where separate washing and drying compartments are provided side by side, the resultant machine is necessarily expensive to manufacture and requires considerable space.
The main object of our invention is to provide a liquid extractor to be used in. conjunction-with a washing machine which, is safe to use, and which can, under no possibility injure the clothes.
Another object is to provide a device of this character which can be suspended on a washing machine vat wholly within the circumference thereof, thus conserving space.
Another object is to provide an apparatus which requires no driving mechanism and no expenditure of power other than that derived from tap water.
Another object is to provide an apparatus which is silent in operation and free from. all vibratory or other undesirable movement during A further object is to provide simple and ei- .ficacious means ror-supplying-pressure to the extractor vat ior extracting the liquid from the clothes contained therein and to relieve this pressure after the clothes have been dried to the desired degree.
Other objects and advantages relate to the details of form and arrangement of parts-all as will more fully appear from the following description taken i i-conjunction with the accompanying drawin s, in which:- K Figure -1 is a top plan view of our device in position onawashing machine vat.

Figures 12, 13 and 14 are diagratic views illustrating respective fluid control systems whereby fluid as water, may be supplied'to the ex-' driven in any conventional way. The means for.
oscillating the dolly not being a part of this invention, such means has only been indicated gen- Our extractor comprises an annular trought having an aperture 6 in its bottom. Trough b has secured thereto a plurality, in this instance shown as three, of circumierentially spaced lws l secured to trough 5 as by bolts 8..
The legs 1 extend outwardly and downwardly from. the trough '5 and are adapted to rest on the shoulder 2 on vat i to hold the trough b suspended over vat II and coaxial therewith.
A short distance beneath trough 5 is positioned an annular strap 9 which is secured as by bolts ill to legs i to stabilize such legs, and also to act as a stabilizer. for the extractor vat about to be described.
The extractor vat H, '(see Figure 3) has its upper edge rolled outwardly and downwardly, and
is inserted through trough B and strap a and moved downwardly until the rolled upper edge thereof engages the inner wall of the-trough 5.
A flexible water impervious bag or clothes conpreferably made of rubber, but it may, if desired,
be made of other appropriate material which is impervious to water.
An annular channeled ring I3 of inverted U- shape in cross section is fitted snugly over the upper edges of clothes container I2 and vat II to retain the same in position on the Wall of trough and form a base for fluid passageways to be later described.
A circular frame or hood I4 is positioned on the outer wall of trough 5 and is secured thereto as by bolts I6. Frame I4 (see Figure 2) is provided with a plurality of circumferentially spaced ribs l5 which contact with the upper face of ring I3 when the frame I4 is in position on the outer wall of trough 5 to maintain the parts tightly in position, the spaces between the ribs forming fluid discharge passageways leading from squeezer |2 to trough 5.
Frame I4 is secured to trough 5 partially by bolts I6 and partially by the bolts, 8 at different points in the periphery thereof.
Frame l4 being bolted to trough 5 with ribs I5 in contact with ring I3, the clothes container I2 and the extractor vat II are rigidly secured to trough 5, the entire structure being removable as a unit.
The inner edge of ring I4 is castellated to form? plurality of spaced inwardly extending ugs A bracket I8 has one end hinged to ring I4 and extends inwardly. On the inner end of bracket I8 is rotatablymounted on a headed post I9, coaxial with vat I I, a circular cover 20. (See Figure 3.)
For the purpose of limiting the downward movement of cover 20 in ring I4, we provide on the edge of cover 20 an outwardly extending lug 22 which is adapted to contact with the upper face of ring I4 when the .cover is moved to the closed position. On the edge of cover 2|), we provide an upwardly extending knob 23 'by which (waiver 20 may be conveniently rotated on its pivot When the cover 20 has been brought to the closed position and it is desired to operate the device, such cover 20 is partially rotated by means of the knob 23, and this partial rotation of the cover 20 will bring the lugs 2| on the cover 20 beneath the lugs IT on the ring I4 so that the cover 20 will be locked in the closed position.
For the purpose of limlting'such movement of the cover 20 so that it will be conveniently brought to rest in either the locked or unlocked position, we provide on bracket I8 opposed boss es 25 and 26 with which the finger 24 contacts to limit the rotary movement of the cover 20.
Referring to Figures 4 and 5, we provide on the under face of trough 5 a spout 21 swingingly mounted on a headed bolt 28 which is secured to the under face of trough 5.
. Spout 21 has an outwardly extending lip 25 by which it is mounted on bolt 28.
We provide adjacent the upper end of bolt 28,
a washer 30, and adjacent the lower end thereof and against the head of such bolt, 9. second washer 3|.
A spiral spring 32 encircles bolt 28, and is seated against the opposing washers 30 and 3| to urge trough 21 upwardly into frictional contact with a washer 33 interposed between it and the under surface of trough 5 so that the spout 21 will be frictionally held in an adjusted position.
When the spout 21 is in this position, it extends outwardly beyond the vat I so that any liquid discharged therefrom will be discharged extraneously of such vat I.
If it is desired to return the washing fluid extracted from the clothes to the washing vat, the trough 2'! is swung about its pivot28 to bring the inner end of such spout outwardly and out of registration with the aperture 6. This will permit any liquid escaping from the trough 5 to therefrom, it will tend to passdirectly through the body 35 rather than into the laterallyextending arm 81.
On the lower end of body 35, we provide a discharge spout 38 secured in position as by a bolt 39 and having adjacent its lower end a cross strap 40.
The lower end of body 35 functions as a seat for a valve 4| which is carried on the end of a rod 42 which is threaded in cross strap 45.
On the lower end of rod 42, we provide a handle 43 so that rod 42 may be conveniently rotated to move valve 4| towards and from its seat.
On the upper end of nozzle 35, we provide a rotatable internally threaded collar 44 by means of which the device may be secured in position on a faucet 45.
The arm 31 is connected as by a conduit 45 to a spout 41 secured to the under surface of extractor vat II and in communication with the interior thereof. When it is desired to extract liquid from clothes, they are placed in the container I2 and the cover 20 is locked in the closed position. The valve 4| is then seated on the end of body 35 and the faucet 45 is opened. The tap water cannot escape past valve 4| and it therefore flows through conduit 46 and into the extractor vat II. The water will force the squeezer or flexible bag I2 upwardly to carry depending upon clothes, the valve 4| is opened and the water 36 past the arm 31 will cause the'water in the extractor vat II to be drawn outwardly'through the conduit 46 and discharged past the valve 4|,
and the extractor vat II will thus be emptied in preparation for thereception of another batch of clothes.
In Figure 2, we have shown conduit 46 connected to a spout 41 eccentrically positioned in the bottom of extractor vat ll. As a modification of our invention, we have shown in Figure 8 extractor vat ll secured to the upper end of vertical conduit 49 which extends through a hollow shaft 50 on which the dolly and a portion of its operating mechanism is mounted. In this construction, the conduit 46 is connected to the lower end of the conduit 49, In this embodiment, the'extractor vat ll is provided with an internally' threaded boss 5| adapted to engage the threaded upper end of the conduit 49 so that extractor vat ll may be conveniently placed in position on conduit, 49 or removed therefrom.
In'Figu'res 9 and 10, we have shown a'struc-- ture which is identical in all material respects with the structure shown'in Figures 1 to 7 inclusive with the exception that instead of having three similar legs as I, by which the extractor basket i l is suspended co-axially with the washer vat i, we have provided a pair of comparatively long legs 52 together with a comparatively short vertically extending leg 53 so that the extractor basketl l is suspended eccentrically of the washer vat l and adjacent the edge thereof.
In Figure 11, the extractor basket ll issuspended in the same way as shown in Figure 9, but in this embodiment we provide a conduit 54 similar to the conduit 49 shown in Figure 8 .which extends vertically through the dolly supporting means, and which is connected to the bottom of the extractor basket It as by aninternally threaded rotatable collar 55.,
The structurehere disclosed is one which is very compact and space-saving in that the extractor is supported onthe washer vat wholly within the circumference thereof so that the space required is merely the space required by the washer vat. n
It is also an arrangement .which is convenient tense in that the extractor may be very easily removed from the'washer vat when it is desired to clean the same or if theoperator prefers to have the extractor in a different place. In the structure disclosed in Figures 1 to .7, and in Figures 9 and 10, the operator merely has to lift the extractor off from thewasher vat.
In the structure disclosed in Figures 8 and 11, the extractor basket may beeasily disconnected from the feed conduit and then lifted bodily from the tub.
In Figures 12, 13 and 14, we have illustrated v various water control systems adapted to increase the pressure of the water in the extractor vat in case the pressure of the water from the source is' insuflicient to extract the liquid from the clothes contained in the extractor vat to the desired extent.-
'I'hissystem consists of suitable by-passes connected with the supply conduit for the extractor vat composed of pipes or tubing having suitable pumps and control valves 'connectedtherewith which are adapted to increase or boost the pressure ofthe water to the desirecldegree for extracting the liquid from the clothes contained in the container I2 in the manner hereinbefore described.
The supply conduit 60,. in this instance, is
. provided with a check valve 6! intermediate its ends and which is adapted to permit the water to flow therethrough in one direction only; that' is, from the ejector to the extractor vat. A
supply by-pass conduit 62 is connected with the supply conduit 60 at opposite sides of the check valve. This by-pass conduit 62 is provided with a suitable pressure pump 63 which, in this instance, is represented as a gear pump adapted to draw the water from the ejector and to force the same into the extractor vat II and maybe operated from any suitable source of power such, for instance, as the mechanism for operating the dolly 3 in the washer vat I and which is not necessary to herein illustrate or describe as it does not constitute any part of this invention.
In order that the pressure in the vat II will not becomeexcessive when the .pump is operated, a relief conduit 64 is connected with the supply by-pass conduit 62 at opposite sides of the pressure pump 63 andthis relief conduit has secured therein a suitable relief valve 65 adapted to open at a pre-determined pressure to permit water to be -re-circulated'through the pump. A second conduit 66 having a control valve 61 operably.
manipulation of the handle 43 in the mannerpreviously'described, and with the control valve ii'l in the closed position, the faucet 45 may be opened after which the water will pass from the ejector 34 into thesupply conduit 80 and through the check valve 6! into the extractor vat H.
The water will force the squeezer or flexible bag 12 upwardly to carry the clothes against the upper surface of the cover 20, and if the pressure is insufficient to extract the desired amount of liquid from the clothes, this pressure may be increased by setting the pressure pump 93 into operation which supply conduit 99 at the inlet side of the check valve 6! and return it to the supply conduit 60 at the outlet side of said check valve thereby closing the check valve which will cause the water to be forced into the vet i i under gradually increaspressure in the vat has ing pressure until the been increased sufiiciently to extract the liquid from the clothes to the desired extent after which will draw the water from the the operation 'of the pressure. pump 69 may be will cause the water in the extractor vat l I to be drawn outwardly through the conduit 50, return ejector in'the manner-previously, described, which conduit 60 and the return conduit 66 at which point a suitable straight valve 69 is positioned,
, as illustrated.
This valve 69 is adapted to permit the water coming from the source to fiow straight through the conduit 60, as illustrated in the drawings, or maybe turned at right angles to the position shown for connecting the return conduit 66 with the conduit 62. Furthermore, the supply by-pass conduit 62 is connected at the outlet side of the pump 63 with an outlet'conduit III which may, as shown, be provided with a suitable nozzle or spout 'II for directing the discharge water, as desired, as will presently be more fully explained.
At the junction of the outlet conduit 'III' and the supply by-pass 62 is positioned a two-way valve I2 adapted to direct the water through the conduit 62 or from the conduit 62 into the outlet conduit I0.
In this instance, the source of water supply may come from the faucet or from a suitable storage tank as I3. If the water is to be taken from the tap, the inlet end of the conduit to may be connected with the faucet 46, as illustrated by full lines, and if the water is to be taken 7 from the storage tank I3, the inlet end of the conduit 60 may be extended into said tank, as illustrated by dotted lines. In either instance, when supplying the vat II with water, the valve 69 may be positioned, as illustrated in the drawings, directly connecting the conduit 62 with the inlet of the conduit 60 whereupon the pump 63 will draw the water from the source and force it through the two-way valve I2 which.is positioned, as illustrated, to permit the flow of water through the conduit 62 and thence throughthe outlet end of the conduit 60 and conduit 46 into the vat II in the manner previously described for the construction shown in Figure 12. I i
When it is desired to empty the vat II, the valve 69 may be turned at right angles to the po sition illustrated in the drawings, connecting the return by-pass 66 with the conduit 62 and the valve I2 may be turned to connect the conduit 62 with the outlet conduit III, whereupon the pump 63 will then draw the water from the vat I I through the conduit 49, the adjacent end of the conduit 60' and thence through the by-pass' conduit 66, valve 69 and conduit 62' to the conduit 62, thence through the pump 63, conduit 62 and through the valve I2 to the conduit III and thence out through the spout II.
This discharge water may be returned to the storage tank I3 if desired, as indicated by dotted lines, or may be discharged as otherwise desired, such as into the washer vat I or into the sewer.
In Figure 14 is illustrated a still further modifled form of control system in which the supply conduit 60 may be connected with the faucet 45 or storage tank 13 in the manner illustrated and described for thedevice shown in Figure 13. In this instance, however, the outlet conduit as I0 is provided with a volume pump I6 which is adapted to discharge the water at a much greater speed than when the pressure pump 63 is utilized and for this reason, the valve I2 is adapted to connect the vat II with the outlet conduit 10' without the necessity of the water passing through the pressure pump 63, and in order that the washer vat I may also be emptied by this same pump, we have shown a discharge conduit as I6 connected with the valve I2 at right angles to the outlet conduit III and which is connected with the vat I by means of a spout 11.
When it is desired to extract the liquid from the clothes contained in the extractor bag I2, the valve 12 may be positioned as illustrated in Figure 14 for permitting the water to pass through the conduit 62 after which the water may be drawn by the pump 63 from the faucet 45 or'storage tank 13 in the manner described for the device shown in Figure 13 and forced upwardly into the vat II, and when it is desired to draw the water from the vat I I after extract- H ing the liquid from the clothes, the valve I2 may be turned to connect the conduit 62 with the out- *let conduit I0 at which time the pressure pump 63 may be discontinued and the volume pump I5 set into-operation to draw the water from the vat II and discharge as desired, in the manner described for the device shown in Figure 13.
In the device shown in Figure 14, the pressure pump 63 may also be utilized to supply the washer vat I with water, in which case the valve I2 may be turned to connect the conduit 62 with the conduit I6 connected with the vat I at which time, it is obvious, the operation of the pump 63 will draw the water from the source of supply and force it through the valve 12 and conduit I6 into the vat I.
Likewise, the water contained in the vat I may be drained therefrom by the volume pump I5 by turning the valve I2 to connect the conduit I6 with the outlet conduit III.
