WASHING MACHINE;

A lication med December 21, 1925. Serial 80, 78,918.

My invention relates to improvements in washing machines, and it consists in the combinations, constructions, and arrangements herein described and claimed An object of my invention 1s to prov1de a washing machine in which novel means 1s provided for forcin the water into the clothes, thus permitting the washing cyl1n-' der to be rotated continuously in one direction, instead of being reversed in its movement after being rotated a few turns, as is now the practice.

' A' further object of my"- invention s to provide a washing machine of the typedescribed in which the cylinder is divided 1nto a number of clothes-receiving compartments, these compartments being arranged in such a manner as to lift diflerent portions of the clothes in the cylinder at different times, whereby the weight of lifting the clothes is uniformly distributed throughout one complete rotation of the cylinder. In this way, the cylinder is freed from lifting anundue weight at any one point of its revolution.

A further object of my invention 1s to provide a washin machine of the type describedwhich ma es use of a gearless drive connection between the source of power and the washing cylinder.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated 1n the accompanying drawings, forming part of th1s application, in which Figure 1 is a side elevation of the device,

showing the outer casing partially broken away, I v

Figure 2 is a section along the line 2-2 of Figure 1,

Figure 3 is an end elevation of the device, Figures 4- and 5 are enlarged detail sections of the device, and

F'gure 6 is a diagrammatic view showing the arrangement of the partitions in the cylinder.

I In carrying out my invention, I provide anouter casing land support this casing on uprights 2. In Figure 2, I show how the.

'sition indicated by the .ing the cylinder 5 with casing 1 has an opening 3 therein. Thisopenin is normall' closed by a door 4 of the sli 'ng type. 11 Figure ,2, I also show how the door 4 may be swung into open podotted lines, thus permltting the'operator to gain access to the interior of the casin In the casing 1, dispose a cylinder 5. Trunnions 6- rotatably support the cylinder 5 and'are journalled in the casing 1.- The trunnions carry friction ulleys 7.

I will now described t e means for operatin the washin clear y shown in igure 3 and comprises a driving shaft 8 on which friction pulleys 9 are mounted. An idler frictionr is carried by a lever 11. The lever 11 in turn is rigidly secured to a shaft 12, the shaft in turn being rotatably mounted in uprights 13. There are two levers ,11 provided and two idler pulleys 10. The idler pulleys 10 may be swung into engagement with the pulleys 9 and. 7, thereby connectthe drive shaft 8 and causing the cylinder to rotate in the direction of the arrow shown in Figure 2.

en either one of the levers 11 is raised, the cylinder 5 is disconnected from the drive shaft 8. This is a very simple drive mechanlsm. for connecting the cylinder with a source of power and for causing the cylinder t rotate in one direction.

I wil now describe the-novel arrangement for cau mg the water to be forced through the 010 es. Figure 2 shows how the cylinder us perforated, the portions cut out for the perforations being bent to form lips 14. In Figure 5, I show a fragmentary portion of the cylinder fi andv show how the open machine. This means is As heretofore stated,-

pulley 10 i It should be noted in this case that the 109 outwardly bent lips 14 also perform another function. If the openings 15 were not provided with the lips 14, buttons or other projections carried by the clothes would be received in the openings, and would then carry the clothes around with the cylinder during the further rotation of the cylinder.

' With the present construction, however, the

' 18 are projection when slipping into the opening 15 would be cammed out of the opening and back into the cylinder due to the cam surface 17 of the lips 14. In this way, I prevent the clothes from becoming caught on the .wall of the cylinder 5.

At this point, it is well to mention the special constructions of each of the four compartments shown in the cylinder 5. It is obvious that one or more compartments may be provided in the cylinder without departing'from the spirit and scope of my invention. I have shown four of t ese compartments in Figure 1. The compartments formed by transversely extending partitions 19. Each of these compartments 18 is divided into two equal parts 18 and 18", see Figure 2, by a diametrically disposed partition 20. There is a partition 20 disposed in each. compartment 18, and these partitions .are inclined at difl'erent angles.

with respect to each other for a purpose now to be described. In Figure 6, I show a diagrammatic view of the casing 5 and of the .four partitions 20, 20, 20 and 20. These partitions are disposed 45 apart. I further show in Figure 2 how each of the partitions 20 is composed of two sections, the section 20' being rigidly mounted in the cylinder, while the section 20" is pivotally mounted at 21. The section 20" may be swung into the dotted line position :2: or y. The section 20! acts as a door for the compartment 18 or 18 and the frictional contact between the ends of the section 20" and the partitions 19.is suflicient to hold the section 20 in the central position while the door 24 is moved into closed position, ositioning the lugs 25 one upon each side 0 the section 20". The clothes are disposed in either one of these compartments. The same is true with all of the other compartments 18 in the cylinder) Again referring to Figure 6, it will be noted that the clothes in the cylinder 5 will be divided into four bundles. During the rotation of the cylinder 5, each one of these bundles will be lifted from, the water 16 in consecutiveorder instead of all being lifted at the same time. This uniformly distributesthe load on the machine through one complete revolution,

instead of having the load all applied at one time as would be the case if the artitions 20 were all disposed in the same p ane.

In Figure 2, I also show the partition 20 as being perforated. The openings 22 have lips 23 extending in opposite directions,

door 4 is opened The lips 23 act in the same manner as the lips 14 and prevent the clothes from catching on the walls of the openings.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The and so also is the door 24 of the left hand compartment 18 in Figure 2. The section 20 ma now be swung into either of the two dotte line positions a; and

y to permit the clothes to be disposed in either the compartment 18 or the compartment 18 When this has been done, the section 20 is swung back into the full line position and the door 24 is closed causing the lugs 25 to receive the free end of the section 20", thus locking the section in place. The next compartment 18 is filled 1n the same manner, and this is repeated until all of the compartments are filled with clothes. If desired, both parts 18 and 18 of each compartment 18 may be filled with clothes, but I have found that a better washing is accomplished by filling only one of the compartments 18 or 18". The doors 24 when closed are locked in closed position by any means, such as by a sprin catch 26. The door 4 is now closed an water is admittedto the casing 5 through the inlet pipe 27. Soap may be added if desired and then the cylinder 5 is connected to the drive shaft 8 by means of the idler pulleys 10, as heretofore described. The washing operation is continued as long as desired to efiectively clean the clothes. After a sufficient time has elapsed, the cylinder is brought to a stop and the clothes are removal. 1

If desired, the rinsing and the bluing operations may be carried on without the necessity of removing the clothes. Outlet open-- ings 28 controlled by the valves 29 and ahand or foot lever 30 permit the water to escape from the casing 1. Additional water may be added to the casing and the clothes may be rinsed in this clean water. The device is extremely simple in construction, and is durable and eificient for the purpose intended.
