Be it known that I, PHILIP H. WALLER, a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Washing Machines, of which the following is a speclfication.

rlhis invention relates to a washing machine which is more particularly designed for washing clothes, fabric or similar articles, and has for its objects the provision of a machine for this purpose which enables clothes and the like to be not only effectively washed, but also wrung or separated from the bulk of the washing liquid in the same machine and by means which are sim le and compact in construction, easily opera le and not liable to get out of order.

ln the accompanying drawings: Figure 1 is a vertical section of a washing machine embod ing my invention, the section being taken engthwiseof the main driving shaft. Figure2 is a fragmentary vertical section taken on line 2 2, Fig. 3. Figure 3 is a view similar to Fig. 1 but taken at right angles thereto and showing a pump whereby the washing liquid is removed from the tank. Figure 4 is a fragmentary horizontal section, taken on line 4-4, Fig. 3, looking upwardly. Figure 5 is a bottom plan view of the machine showing the bottom parts of the pump casing and the worm gear casing removed. Figure 6 is a fragmentary horizon tal section taken on line 6 6, Fig. y.1, looking upwardly. Figure 7 is a fragmentary lside elevation showlng the means for holding in position the lever which controls part of the gearing for operating the washing tub. Figure 8 is a vertical section taken on the correspondingly numbered line in Fig. 7.

Similar characters of reference refer to like parts throughout the several views.

Although the main frame. of this machine may be of any suitableconstruction, that shown in the drawings comprises a base 10 of skeleton form of a suitable shape to support the working parts of the machine and provided at its periphery with a plurality of downwardly projecting legs 11 which rest upon the iioor or round.

Supported on this frame is a tank which is adapted ,to enclose a washing tub and to receive the washing liquid from the latter after the washing of the articles in the vtub has been completed. This tank comprises a upper side of the base 10, an upright cylindrical wall 13, rising from this bottom and preferably provided with a depending skirt 14 which encloses the working parts of the machine which are mounted on the main frame below the tank, an annular flange 15 removably secured to the upper edge of the Uro;

tank wall so as to project inwardly therefrom and a cover 16 detachably secured to the upper end of the tank wall and forming a closure for the top of the tank. Byemploying the iiange 15 the water for washing the clothes which is discharged laterally from thev wash tub during the o eration of draining the clothes, is prevente from etting over the upper edge of the tank an is f compelled to go downwardly and accumulate in the lower part thereof.

The wash tub which is arranged within the tank preferably comprises a horizontal bottom 17, an annular side wall 18`of conical form which ,ares upwardly from the margin of the bottom 17 and is provided adjacent to its upper edge man annular row of drain openings 19, and an annular fian e 20 projecting inwardly from the wall o the tub above said drain openings. Meansare provided for imparting either a slow oscillating or rocking motion to the 'wash tub or a very rapid continuou'srotary motion in the same direction, said oscillating-motion being or other articles in t e tub, so as to cleanse `the same in the body of the Washing liquid in which the same are immersed. while the rapid continuously rotating motion is utilized for draining the water from the clothes after the same have been washed and discharging this washing liquid into the surrounding tank.

While the clothes are arranged in the tub, means are provided -fo'r holding the same in a compact mass in the lower part of the tub and also exerting a rubbing action on the same while an oscillating motion is imparted to the tub and the clothes. These means preferably comprise a hub 22 secured centrally tothe bottom of the tub and provided with an upwardly projecting post 2 3 which is preferably square in cross section, and a rubbing disk or board 24 having its hub provided with a square opening 25 which receives the post 23 and is provided on its bing disk plate is free to slide vertically on the post and adapt itself to the top of the batch of clothes in the tub, butisycompelle'd to turnl with the post and tub so that the ribs on the underside ofthe rubbing disk exert a rubbing action on the clothes. By constructing the ribs 26 in the form described they do not. only operate to rubthe clothes,` but also to shift the mass of clothes step by step circumferentially in the tub,

. inasmuch as the inclined sides of these ribs slide over the top of theclothes while the abrupt sidespof the same operate to push the clothes, thereby serving to turn the clothes over progressively and bring all parts of the same under the rubbing action rof the rubbing board and its ribs.

The tub is removably mounted upon an upright driven shaft 27 which ,has its central part journaled in a bearing 28 projecting from the base of the main frame upwardly into the lower part of the tankso that the lower end of the shaft is below the base and the upper end of the same is arranged within the. tank. The downward movement ofthis shaft on its bearings is limited by means of a collar 29 secured thereto by meansof a pin 30 and resting on the upper end of the bearingv 28.

The post 23 is hollow and receives the up-- per end of the driven shaft 27 and the downward movement of the tub may be limited by engagement of its hub 22 with the collar 29 and by engagement of the upper end of the hollow post 23J with the upper end of this shaft, as shown in Fig. 1.

Means are provided for permitting the tub to be moved longitudinally on the driven shaft for assembling Jand dismembering these parts but compelling the same to turn together when the parts are assembledand ready for washing a batch of clothes.

The preferred means for this purpose as shown in Figs. 1, 2 and 3, consist of a pair of coupling lugs 31 arranged on the upper side of the collar 29 on diametrically opposite sides thereof and engaging with recesses 32 in the underside of the hub 22 in the tub. By means of these co-operating surfaces, the collar 29 and the hub 22, the

- tub may be interlocked with the shaft so as to turn therewith when the tub is in its lowermost. position and the latter may be conveniently lifted ofi' from the shaft when required. Y

The means for imparting a rocking or oscillating motion to the tub for washing .al

batch of clothes are preferably constructed as' follows: l

33 represents a-driven vspur gear wheel i mom mounted on the driven shaft below the base 10 and 34 is a'horizontally'swingin rock lever plvoted atone end on the un erside vof( theF base l0 and provided with a'gearc` segment 35 which meshes with the spur gear J wheel 33 so that upon rocking this lever an oscillatlng motion will b'e imparted to the tub and the parts associated therewith/This oscillating motion may be obtained in any suitable way, but preferably by means of a rotary crank arm 36 provided with a wrist pin 37 whichJmoves in a longitudinal slot or guide way 38 formed in the outer 4or free end of the rock lever. The crank arm is secured to the upper end of an intermediate shaft 39 which is journaled in aV bearing 40A formed on the upper side of the worm gear casing 41, the lower end of said intermediate shaftbeing provided within this gear casing with a worm wheel 42. 43 represents a horizontal driving shaft which is journaled in suitable bearings on the main frame and provided at one end with aworm 44 which meshes with the worm wheel.42 while power is adapted to be applied to the opposite end of the shaft by yany suitable means, -for instance, by means of an electric motor 45 or other prime mover mounted on the underside of the base plate and connected with the driving shaft, as shown in Fig. 5. By means of thisgearing a comparatively slow oscillating' or rocking motionis imparted to the tub, which causes the clothes or other articles therein to be effectively rubbed o1' scoured and cleansed. The wash water, by reason of being. alternately moved in opposite directions at short intervals and at slow speed, will not rise to Vthe top of the tubl and escape through the drain openings 19 thereof.

After a batch of clothes or other articles have been subjected to therubbing or washing action of the tub and associated parts for a sufficient length of time, the slow speed mechanism whereby a slow rocking motion is transmitted from the main driving shaft to the upright driven shaft is rendered in operative and instead means are rendered operative which cause motion at a relatively high speed to be transmittedsfrom the main driving shaft to the tub shaft so as to rotate or whirl the tub rapidly and continuously in the same direction a sufficient `length of time to effect draining of the excess water from the clothes in the tub. The means whereby this is accomplished are preferably constructed as follows v 46 represents a driven beveled gear wheel which is mounted on the lower end of the driven shaft 27 and adapted to be either coupled with 0r uncoupled from said shaft and meshing constantly with a driving 'beveled gear ywheel 47 Vsecured to the driving shaft 43. The driven bevel gear wheel 46 at times turns loosely on' the lower end" of the tudinal movement on this shaft driven shaft 27 and is confined against longiy means of a downwardly facing shoulder 48 on this shaft engaging with the upper end of the hub of this beveled wheel and the washer 49- -to be coupled with the hub of the gear wheel 46 by means of a pair` of coupling lugs 53 arranged on the hub 51 and adapted to engage the' coupling recesses 54 in the upper P end on the hub of the gear wheel 46. In the position of the parts shown' in Figs. 1 and 3, the spur gear wheel 33 is in its uppermost position and engages with the gear segment 35, whereby an oscillating motion for washing purposes is transmitted from the driving shaft 43 to the tub. Upon moving the gear wheel 33 downwardly out of engagement from the gear segment 35 and into its lowermost position the coupling lugs 53 of the spur gear wheel 33 will engage the notches 54 of the driven bevel wheel 46 so that now a rapid motion will be transmitted from the main driving shaft 43 to the tub for turning the latter at high speed continu ously in the same direction. When this occurs the water in the clothes or other articles is drained by centrifugal force out of the same and caused to move upwardly along the inner side of the tub wall and finally escapes through the drain openings 19 into the water tank whichl surrounds the tub., this rapid rotary movement of the tub being continued a suiicient length of time to thoroughly remove from the clothes all of the excess water so that the clothes when removed from the-tub are ready to be completely dried in the usual manner by hanging the same out on a line, placing the same in a clothesdrier or otherwise.

When the spur gear wheel 33 occupies an intermediate position between the gear segment 35 and driven bevel gear 46, then the driving mechanism is neutral and no motion is transmitted from the driving shaft to the tub, at which time, clothes may be either introduced into the tub or removed therefrom as well as any other functions which require the tub to remain at rest.

For the purpose of conveniently shifting the spur gear pinion either into its neutral central or into its upper or lower positions, for either rocking the tub slowly or rotating the same at high speed, means are provided which are preferably constructed as follows:

-55 is a vertically swinging rock lever 10 and provided on its inner. arm with a vfork 56 which engages with an annular groove 57 on the hub 51 of the spur gear wheel, while the outerarm of this lever r0- jects through a vertical slot 58 in the s irt 14, as shown in Figs.y 1, 5 and 7. j

59 represents an upright shipper rod arranged outside of the skirt and wall of the tank and connected at its lower end with the outer end of the shifting lever 55.y The upper partr of this shipper rod passes through thel upright guide'loop -60 of a bracket, which is secured to the outer rside of the tank wall 13 and provided with an upright slot 61 which receives an adjusting or retaining shank 62 connecting the upper art of the shipper rod 59 to the handle 63. This slot 61 is constructed to form a vertical series of shoulders 64, and 66, which are arranged progressively atf different heights and adapted to receive .the adjusting shank 62 for the purpose of holding the spur gear wheel 33 in different positions. Three of such shoulders are employed, as shown in Fig.17, the lowest one 64 corresponding to the position of the spur geary wheel wheny in its uppermost position and engaging with the segmental gear 35, the intermediate shoulder 65 corresponding to the position of this spur gear wheel'when the same is neutral and out of engagement from the driven beveled gear wheel 46 and the segmental gear 35, and the highest shoulder 66 correspond ing to the position of the spur gear wheel 33 while the same is in its lowest position and engaging withthe driven bevel gear wheel 46. By this means the driving mechanism of the tubican be regulated and conveniently operated so as to either stop the rotation of the tuby or cause the same to be oscillated slowly for washing a batch of clothes o-r to be rotated rapidly in one direction for draining the water from the clothes.

After the water has been discharged from the tub to the tank, the water may be removed from the latter and conducted to a waste if the same is not clean or no longer required, or this water, when sufliciently clean, may be again returned to the tub for use in washing another batch of clothes. The mechanism for accomplishing this purpose is constructed as follows: A

67 represents the casing of a rotary pump which has an inlet 68 in its upper side which communicates with an outlet 69 in the bottom of the tank. Onl one part of its periphery this pump casing is provided with an outlet 70 to which one end of a flexible tube 71 is connected, the opposite end of this tube beingprovided with a nozzle 72 and a valve 73 whereby the discharge of water from this tube may be controlled. When this tube is not in use the same may be su ported at its free end on a clip 74 secure to the i which is pivoted on the underside of the base tub on said shaft and to be ,impeller shaft 76 journaled in a bearin on Within the pump casing is a rotary impeller 75 which is secured to the upper end Aof an ythe lower side of the pump casing. his

- shaft is turned by means of a belt 77 passing around a driving pulley 78 formed on the hub of the driven bevel ar wheel 46 and also around a driven p ley "79 secured to the lower end of the impeller shaft, as best shown in Fi 3. By means of this driving mechanism. or the pump, the impeller will not only be o rated, whenever, the driving shaft isturne at which time the water may be removed from the tank by means of the pump to any suitable placeI upon openmg the"'valve 73 of the delivery tube 71. If desired, the water may be dlscharged from the tank while the clot es are being drained, or the valve 73 may retained in its closed position, at which time the impeller 75 of the pump will simply rotate idly with1n its casing without accomplishing any purpose or doing any harm.

If it 1s desired to return the water from the tank to the tub for using the same over i a again on another batch of clothes, the water may be delivered by the hose. 71 tothe tub while the driven spur gear 33 is in its central position and the'tub is not turning at this time.

As a whole, this washing machine is very simple and compact in construction considering the various functions which it performs,

it has no delicate parts which are liable to get out of order and the various parts may be readily adjusted for performing the vari-y ous necessary operations to complete the washing and draining of a batch of clothes.
