WASHING MACHINE.

Application filed July 2,

To all whom it may concern:

Be it known that I, MAUDE B. LATSHAW, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Vashing Machine, of which the following is a specification.

My invention consists of a washing machine embodying a beater mechanism for raising, lowering and rotating the latter, and

the provision of chambers in said heater where the clothes or articles to be washed are subjected to the pressure of air in said chambers, as well as the members of the beater itself, provision being further made for relieving said chambers of the excess of air in said chambers and forming vacuums in thelatter so as to permit the heater to descend in the water to the extent of its motion so as to be eased in said motions.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the scope of the claims.

Figure 1 represents a vertical section of a washing machine embodying my invention. Figure 2 is a perspective view of the lower mechanism of the device on an en larged scale.

Figure 3 represents a partial side elevationand partial vertical section on line 3-3 Figure 2.

Figure 4 represents a vertical section of the beater and appurtenances on an enlarged scale.

Figure 5 represents a horizontal section on line 55 Figure 4.

Figure 6 represents a perspective view of the beater on a reduced scale.

Figure 7 represents a transverse section of a portion on line 77 Figure 5.

Figure 8 represents a vertical section of a portion detached from the right hand side of Figure 1.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings,

1 designates a tub of suitable construction, and 2 designates a beater therein, said beater being connected with the rotatable and vertically movable shaft 3 which depends from the heater and is passed through an opening 4 in the bottom 5 of the tub and 1923. Serial No. 648,862.

extends below said bottom where it has secured to it the ratchet 6 whose teeth are adapted to be engaged by the pawl 7 which is mounted on the yoke 8, the inner end of the latter being secured to the collar 9 which freely encircles the shaft 3. Connected with said collar is the arm 10 on whose terminal is mounted the toggle-like lever 11 which depends from said terminal and with whose limbs are Pivotally connected one of the swinging arms 12. Another swinging arm 12 is pivotally connected with the link 13 which latter and the lower limb of the toggle like lever 11 have their axes 14: on the bracket 15 which is secured to and depends from the table 16 on which the tub 1 is supported.

Pivotally connected with the lower limb of the toggle like lever 11 and with the lower end of the link 13 are the elbows 17 which rise from the cross head 18, the latter having centrally in it an opening through which passes freely the reduced neck 19 on the lower end of the shaft 3, said neck founing at the top the shoulder 20 against which bears freely the central portion of the cross head 18 whereby when the latter is raised it bears upwardly against the shoulder 20 and so elevates the shaft 3. Then as the pawl 7 and ratchet 6 are operated rotary motion is imparted to said shaft, the heater 2 following the motions of said shaft, as will be hereinafter more fully described.

Motion may be imparted to the arms 12 by means of an electric motor 21 whose shaft with the arms 12, and thus said arms will receive rising and lowering motions which are assisted. by the spring 12 which is connected with said arms and the adjacent support 21 for the motor 21.

The beater 1 is a concave body, the central portion of which has therein the vertical walls 24 and 25, which are connected at the top by the wall 26, said walls being separated forming the circular air and water receiving chamber 27. The Wall 21 is connected with the central horizontal wall 28 in which is an opening 29 for the reception of the adjacent portion of the shaft 3, around which opening rises the collar 30 which is bolted or screwed to said wall 28 and is socured to said shaft 3 by the pin 31 which is passed through said shaft and collar.

In the upper end of the wall 25 are ports 32 for the exit of excess air and water in the chamber 27., The walls 24 and 28 form. the central chamber 33 for the reception of air and water, it being noticed that the lower end of the chambers 27 v and 3a are open at their lower ends so as to be in communication with the interior of the tub 1.

Connected with the wall 28 is the tubular nipple 3a which opens into the chamber 33 and is connected with the chamber 35 containing the springpressed valve 36, and a seat therefor, said valve chamber having ports for the escape or the excess of air and water entering the chamber 33.

Extending laterally trom'the wall 28 of the chamber 27 are the wings 37 which are.

hollow torming the chambers 38 therein.

Connected with the upper walls of said wings by suitable nipples are the chambers 39, the same containing the spring pressed valves 39, seats therefor, and ports 4=O for the escape of the excess of air and water from said chambers 39.

it will be noticed that the valve, etc., for

the chambers 33 shown in Figure 4 are substantially the same as the construction shown in Figure 8 for the wings 37 on an enlarged scale.

The operation is as follows, the tub having been properly supplied with water and soap,as in Figure 1 The arms 12 recelve up and down movements from the motor 21, and so causes the toggle like levers 11 to open and close usual QThe beater, thus rotating then enters the ing noticed that the air in the several chambers of the beater also press against the water and rotates and agitates it and'the suds therein. The clothes or other articles in the tub are carried around in the water and suds and highly subjected to the pressure or pounding action of the beater, it be water-in the tub and the articles that are being washed therein and so assist in-pressing and pounding said articles.

Now it is important to relieve the excess of pressure of the air and water in the chambers when the closing action of the valves is overcome and the latter are opened, and so the said excess escapes from the valve chambers and causes vacuums in said chambers, thus allowing the beater to descend more readily to a requisite extent in the nesaesa water and suds. Then thebeater rises and descends when it turns and engages the articles at diflerent places and further rotates the latter in the water and thusefiectively washes the articles.

Having thus described my invention what I claim asnew and desire'to secure by Letters Patent, is

1.. In a washing machine, a beater, a rotatable and vertically movable shatt carrying said beater, a tub in which said heater is operative, said heater being formed of a body provided with a central chamber, a second chamber surrounding the central chamber, an auxiliary chamber surrounding said second mentioned chamber, and wings extending from said auxiliary chamber, said wings having chambers therein, the several chambers being open below in communication with the interior of the tub, and means for relieving said chambers of vacuum.

2.
