WASHING MACHINE Filed March 23, 1951 3 Sheets-Sheet 3 Patented Oct. 24, 1933 ICE a oLFF washing compartments 69. The cages 89 are This invention aims to provide a device for washing clothes and other articles.

It is within the province of the disclosure to improve generally and to enhance the utility of 5 devices of that type to which the invention appertains; v

With the above and other objects in view, which will'appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood, that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed,

.15 without departing "from the spirit of the invention.

In the accompanying drawings:

Figure 1 is a longitudinal horizontal section of the washer, most parts appearing in top plan;

Figure 2 is a transverse section of the washer.

Figure 3 is a longitudinal sectional view of one of the valves which let the water out of the compartments of the washer.

The washer embodies a horizontal, cylindrical 1 5 tank 66, carried by supports 6'7. The tank 66 has ,a plurality of transverse partitions 68 dividing the tank into washing compartments 69. Into these washing compartments 69, pipes '70 discharge, the pipes opening through the upper portion of the tank 66. The pipes '70 extend upwardly and backwardly, and are provided at their upper ends with funnels '71, which receive liquid from a mixer, not shown.

The tank 66 has a plurality of outwardly opening doors '72, there being one of these doors for each of the washing compartments 69. Brackets '73 are secured to the doors '72 of the tank 66, and are secured to a shaft '74, extended lengthwise of the tank, and journaled for rotation in bearings '75 on the tank. Intermediate its ends, the shaft '74 carries an arm I6 the arm '76 projecting from the shaft '74 in a direction opposite to the the arms '73. A counterweight '77 is mounted for sliding adjustment on the arm '76, to offset the weight of the doors '72. This weight 77 may be of any desired size. It is held adjustably on the arm '76 by a set screw '78 threaded into the counterweight.

On the partitions 68, and on the ends of the tank 66, there are bearings '79 carrying glands 80. Axially aligned shafts 81 are journaled in the bearings '79 and in the glands 80. The inner ends of the shaft sections are secured at 82 to the ends of rotatable, cylindrical cages 83, there being one of the cages 83in each of the ings :on' the tank. 'The shaft 89 is supplie at one end with fast "and loose pulleys 91, or ,with any other :suitable means whereby itionzmay be imparted totheshaft.

rota- The tank 66 carries a plurality of depending outlet pipes 92, there being one of these outlet pipes for each of the washing compartments 69. To each of the outlet pipes 92 isv secured a coupling 93 provided at its lower end with an 1 outstanding flange 94 having a recess 95 in which is mounted a valve seat 96. The valve seat 96 is held in the recess 95 by the. oppositely projecting arms 9'7 of a downwardly extended U-shaped guidey98, the arms being held on the flange 94 by securing elements 99.

An upwardly closing conical valve 100 cooperates with the seat 96, and is provided with a downwardly extended stem 101, an upper abutment nut 104 being threaded on the stem 10!. A lower abutment nut 102 is threaded on the stem 101. A compression spring 103 surrounds the stem 101. The lower end of the spring 103 bears on the bottom of the guide 98, and the lower end of the valve stem 101 slides in the bottom of the guide. The upper end of the spring 103 engages the abutment nut 102. The nuts 102 and 104 have rounded ends 105 which project toward each other.

A shaft 106 extends lengthwise of the machine and is mounted for rocking movement in bearings 107 on the supports 67. At one end, the shaft 106 has a handle 108. Arms 109 are secured at 110 to the shaft 106. The arms 199 have forks 111, straddling the stem 101 or" the valve 100, between the rounded ends 105 of the compartments 69 are filled to the desired level,

the outlet valves 100 of Figure 3 being held closed by the spring 103. The shaft 89 is rotated by the pulleys 91, and rotation is imparted to the shaft 81 by way of the pinions 88 and the gear sired to drain the compartments 69, the shaft 106 wheels 87. Assuming that the garments or other articles which are to be washed are in the cages 83, the garments are whirled about, Within the cages, and in the water in the compartments 69, when the cages are rotated along with the shaft 81. When the washing has been carried on to the desired extent, the doors 84 of the cages 83 are opened, the doors 72 on the tank 66 being opened, the weight 7'7 of Figure 2 facilitating the opening of the doors 84. The garments then may be removed from the cages 83. When it is deis rocked by means of the handle 108. The arms 109 on the shaft 106 cooperate with the nuts 104 and 102 of Figure 3 to depress the valves-100,

against the action of the springs 103, thereby opening the seats 96, and permitting the dirty water to run out of the compartments 69 through the pipes 92. When the handle 108 is released, the springs 103 close the valves 100. It will be observed, referring to Figure 1, that separate packages of clothes may be washed in the respective compartments 69, since separate compartments and separate cages 83 are provided. The machine, therefore, can Wash fine white materials, and coarse dye-discharging materials at the same time, without danger that the finer materials will be contaminated by the soiled water from the coarse and more dirty materials.

Having thus described the invention, what is claimed is:

1. In a device of the class described, a washer comprising an elongated horizontal tank, compartments in the tank, the tank having a door- Way for each compartment, the door-ways being aligned longitudinally of the tank, a rotary cage in each compartment, means for connecting the cages for rotation as one piece, each cage having a door-way, doors for the door-ways of the cages and alined longitudinally of the tank, means for rotating the cages, in fixed relation to each other, to bring the doors of the cages into registration with the respective door-Ways of the tank at one time, so that the doors of all thecages may be opened, and for the further purpose of rotating the cages to carry on a washing operation, when the doors of the cages are closed, doors for the i door-ways of the tank, and mechanism for opening all the doors of the tankrat once, to permit doors of the tank, a counter weight offsetting the weight of the doors and slidahly adjustable on the rigid arm, and means for holding the weight in adjusted positions longitudinally of the rigid arm, the shaft being located adjacent to the uppermost part of the tank, and the rigid arm slanting upwardly, to render the weight readily adjustable at the hand of a person standing on the opposite side of the tank from the weight.
