These improvements relate to clothes washing machines of a kind having a clothes receptacle adapted to contain a cleaning liquid and which reciprocates up and. down while oscillating on the axis of reciprocation. The objects'include the provision, of an efficient clothes washer which is notably compact, and occupies but a small amountof space relative to the capacity of a given embodiment;,and one also which is peculiarly appropriate for small-size constructions adapted for use in small apartmentgkitchenettes, and like places where space considera- 15 tions are important. Other objects have to do with" simplicity and strength of the organized parts, convenience use, quietness in operation, and the avoidance of certain conventional features of washing machines 20 found disadvantageous. Other objects and advantages will be apparent from the specification, drawingsand. claims.

In the drawings Fig. 1 is a medial vertical section through a preferred embodiment of 5 the machine complete, with the'motor in full side view; Fig. 2 is a view showi a frag,- ment of the clothes receptacle in si e elevation and in section, as on the line 2-2 of Fig. 1 showing certain of the operating parts; 50 Fig. 3 is a fragmental horizontal section on the line 33 of Fig. 2; Fig. 4-is a small diagrammatic horizontal section through'a modified construction of the container'showing the construction and arrangement of the clothes-pushing members in a container to be considered of sheet metal; and Fig. 5' is aside, a pair of plate-like motor supports 7,

a pair of flat and wide ribs 8 for supporting the operating mechanism, these ribs rising from plates or bottom walls 8a, and an up} right vane, 9, all of these base elementsbe- 50 ing integral with one another and with the 1930. Serial 110,456,848.

outer rim. This open and skeleton form of the base effects a notable saving in weight and cost. The. base is preferably cast. of:

frame having a bottom wall 12, upstanding.

side walls 13 and 14, end walls 15 and 16 and a top wall 17. Laterally-extending, flanges 1.8 at the bottom providemeans for'securing this mechanism frame to thebase ribs 8' by bolts 19.. V I

The motor 20 is secured to the. supports 7 of the base. It has a pinion 21v on its armature. shaft meshing with a gear 22. fixed on a shaft 23 which extends through a bearing enlargement 16a of the end wall 16 of the frame.

I On shaft 23 there is a pinion 24'meshing with a gear 25 shown as integral with a stud shaft 26 extending into a removable bearing member 27 having an annular flange 27a and an annular ridge-like projection 27?), the latter interfitting in an opening 28 in the side wall 14. Bolts 30,. shown dotted in Fig. 1, hold this hearing member 27 in place.

Thedepending boss 33 is formed integrally with the top wall 17 while an upstanding boss. 34 is integrally formed on the bottom 12 and side wall 13 of the mechanism frame, as shown in Figs. 1 and 2. The bosses 33 and 34are bored on. an axial line to accommodate a reciprocable shaftv 35 and to provide a piston chamber 37 for a pump piston 36 respectively. The shaft 35 and piston'36 may be formed, as shown, from, a single piece of metal. The shaft 35 is formed hollow chiefly to save weight. I e

The lower part of vertical shaft 35 is bored diametrically to accommodate, preferably with a working fit, the driving element or pin 40 which has an enlargement or collarlike formation 41 bearing against the side of the shaft 35, and a ball 42 at its outer end.

In the inner face of the gear 25, is a circular recess off-center with respect tothe axis of shaft 26 and accommodating a tubular steel bushing d3 tightly driven into position, the bushing forming a recess 44. (See Fig. 1.) The head 42 of the pin 40 fits snugly in this recess i-i. The head can not move to the right as viewed in Fig. 1 because limited by the depth of recess 44, and the collar 41 bearing against the shaft maintains the head 1-2 against displacement to the left as viewed in Fig. 1. The arrangement described constitutes a universal oint connection.

The motor being in operation, the driving member or gear 25 is rotated at a speed much reduced from the motor speed, and the head 42 and without the pin is carried around in a circle. The shaft 35 must respond to themovements of head 42 and pin 40 because the pin or driving element 410 maintains a constant driving relation to shaft 35. This circular motion of head 42 becomes translated into upward a d downward reciproc tions of shaft 35 coupled with simultaneous oscillation on the axis of shaft 35.

If a cycle of these movements is initiated with the ball-and-socket universal joint 42, l3 at its lowermost position as shown in Fig. 1, the first quarter of the revolution of th gear 25 will raise shaft 35 upwardly the first half of its full stroke, and at the same time will rock shaft 35 one half of its oscillating movement in one direction. The next quarter of the revolution of gear 25 head 42' will carry shaft 35 upwardly the remaining half of its stroke and simultaneously turn shaft 35the first half of its rocking movement in reverse direction. The ball 42 has now moved from its lowermost to its uppermost position as shown in dotted lines in Fig. 1. Continuing through the third quarter of the revolution of the gear 25, shaft 35 is carried downwardly one half its stroke while being turned through the second half of the reverse rocking movement. On the last quarter the shaft 35 descends to intial position at the lower end-of its stroke while being turned through the first half of oscillating movement in said one direction. The rocking movements are reversed when shaft 35 is midway between the ends of its stroke. The beginning of a rocking movement lags ninety degrees in the rotation of gear 25 from the beginning of a reciprocating movement, and vice versa.

Mounted on the upper end of shaft 35 is a support shown as circular in plan view and provided with a hub or shaft extension 51 which is off-center with respect to the circular periphery of the support 50 as shown in Figs. 1 and at. Shaft extension 51 fits on shaft 35, and held securely by a bolt .52 threaded into the lower part of shaft 35. Interlocking means shown as serrations 53 (Fig. 2) insures a positive driving connection between shaft 35 and the hub 51 and its supported parts.

The support or carrier 50 may be ccnsupport from time to time.

sidered to be in the form of a wheel or spider having spoke-like arms 50a 1) connecting the hub 51 to the annular rim, the latter having an upstanding flange 50?).

The kettle, container or rece tacle 55 is shown as a casting which is preferably of aluminum. Such a receptacle may be of sheet metal, and the one marked 155a of Fig. i may be considered such. The kettle 55 has a bottom 56, cylindrical. sine wall 57 and a top wall 58 terminating in an upstanding flange 59. The removable cover 61 has a flange fitting over flange 59. Oppositcly-arrang-ed handle brackets 63 are integral with the top wall 58 and between the brackets of each pair is a wood or composition l i handles enable the container to be i bodily and carried about, while knob 61': enables the cover to be applied and removed.

The container 55 fits loosely within the flan e 50?) of the support and may readily ed away from and reapplied to the This is a feature of importance nukes for greater convenience in the washing operations in general, and this container, with water, soap and the clothes to be cleaned therein may be placed on a stove and the water heated even to boil-- ing if desired, or the water may be heated before the clothes are inserted. No heating device is therefore necessary in connection with. the machine.

Several small upwardly-tapering projections orstuds 67, Fig. 1, carried near the margin of support 50 interfit with simi irly shaped recesses formed in integral enlargements 68 in the corner between the bottom "all 56 and side wall 57 of the lgettle, and

thus the kettle is moved positively by the carrier or support 50 when the latter is oscillated.

The kettle or container 55 moves with the same vertical reciprocation-4 and the same oscillating movements as those given to vertical shaft 35. Fig. 1 shows in dotte' I and somewhat exaggerated, tl 'm of the container when it has reachec maximum throw to the right under oscillatory movement and as the coniainer nears the upper end of the stroke of the p ston. The throw of the container to the ri nt and leftis due to the eccentric arrangement of the container support 50 with respect to the axis of the shaft 35.

lied to the .e container In this machine motion is si kettle contents by moving t bodily. This, for one th g dispenses with the use the conventional reciprocating plun within the body of the container and which occupy a very c ide able amount of space and call for a contai er of mate: rally great 'JlVG for a en capacity, and, further more, the action of such heaters 7 pressers upon the clot es is not entirely sat factory. The present container, being free of such deamps;

vices, will hold for effective washing an unusually large amount of material for a given size of machine.

I provide means for moving the material within the container in the form of a plu rality ofwvedge shaped projections marked 69 in Fig. l and 169 in Fig. 4;. In Fig. 4:

- projections 169 are formed of sheet metal and tainerwhen the containeris rocking in the direction of the arrow in Fig. 4 soas to push the clothing around in the same direction,

while on the reverse movement the more slanting sides 69?) will permit those sides to slide against and away from theclothing rather than to force it back, and thus the material is being moved forward step by step much in the nature of a ratcheting operation. This movement is facilitated by the reciprocations of the container which keep the,

mass of material loosely compacted and in condition for easy movement. A further object of these vaneelike extensions 69, 169

is to agitatethe water and to force it around in the given direction whereby the clothing is carried in a floating manner by the water body. The vertical reciprocations causethe mass of material to rise and fall and spread apart and cause water to pass over and through the same, all as is readily to be appreciated when it is considered that the clothing is being partly floated and-has inertia and momentum and is operated upon by pressures from the various walls of the container. In

" addition to the actions thus described there due to the eccentric motion of the kettle, a bodily throwing of the around in the direction of intended move I *ment. This eccentric movement produces a centrifugal action on the kettle contents which cooperates inthe movement of the wathe base,

ter and solidmaterials relatively to each other and to the kettle.

Returning to the power plant mounted on the chamber 37 communicates by a duct with an oil well 71. When the piston 36 rises oil flows into the bottom of the cylinder chamber, and on the return stroke the piston acts as a'valve to close the duct 70 and then oil below the piston is forced upwardly through an axial bore 72 in the piston 36 into an annular space 73 aroundthe pin 40 for lubricating it. The pin 4.0 has one or more kettle contents 7 holes 7 4 leading to a longitudinallyextending duct 75 which extends through the ball :Oil is thus forced around the pin 41 and into the ball and socket recess M. This recess 44 opens into the bearing surface for the stud shaft 26 and oil may therefore enter that'bearing', and also at the bearing surface between the gear 25 and the bearing member 27. Oil emerging from the severaloutlets coversthe inner face of gear 25 and flows through duct 7 7 into contact with reciprocating shaft 35. ficient for'actual oiling, and the excess flows back intowell 71. Through this oiling system the'parts which would be more difficult to reach are automatically kept well. lubricated.

The eccentric movement of the kettle should not be excessiveowing to the tendency thereby of the device as awhole to creep.

- To gain access to the power plant it is necessary only to lift away the kettle, remove bolt 52 and then'lift'away the housing mexn ber ll- It will be observed that the manufacturing operations call for only what is ordinary and well known, and that the various parts i are "easy of construction and are easily assembled. 7
