UNITED sT Es FREDERICK OWEN,
PATENT, OFFICE.
or DETROIT, MICHIGAN.
WASHING-MACHINE.
- Specification of Letters Patent.
Patented Sept. 2'7, 1921.
Application filed February 28, 1921. Serial No. 448,297.
To alzwhom) it may concern:
Be'it known that I, FREDERICK OWEN, a citizen -.of the United States, residing at Detroit, in the county of Wayne and tate 5 of Michigan, have invented certain new and useful Improvements in \Vashing-Machines, of which the following is a specification.
This invention relates .to washing machines and has for its object an improve washing machine drum that may be driven continuously in one direction as distinguished from the well known oscillatory machine. The object is to provide a drum which is provided with means for working the clothes first to one end and then to the opposite end in such a manner as not to t ngle the same.
In the drawings}- Figure 1 is a side with the lid removed.
Fig. 2 is a cross section on the line 2--2 of Fig. 1.
Fig. 3 is a detail of one of the blades.
- Most machines of the drum type utilize an oscillatory drum which turns first in one direction and then reverses. This requires considerable power to overcome the inertia of the parts in stopping the rotating movement and accelerating the movement in the opposite direction. Furthermore, it requires a complicatedreversing gear and resultsm undue wearing of the parts due tothe stra ns due to stopping the drum and accelerating the drum-in the reverse movement. t 18 the object of the present which can be run continuously in one direction and at the same time get the oscillato movement I for the clothes by causing t em to travel from end to end 0 the cylinder. This is accomplished without tangling them.
In the drawing, a designates a drum which is rovided with an opening I; which may be closed by any suitable lid.
The idea is'simply or elevation of the drum I blades or paddles,
ber of blades for that matter, any
appropriate num v or paddles could be employed. These blades or paddles extend from end to end and are'concave on one side and convex on the other. onl in their broad senses that concave an convex are ap licable to the blade construction shown or the reason hat, blades are not strictly speaking, these to be shown in the rounded but happen axis.
invention to proto employ a pair of drawings as angularly bent in at their centers along the lines 0. However, a technically concave or -convex blade will do the same work, hence I use the words convex and concave in their broader sense, hollow on one side and having a converse constructionon the opposite side. The blades are large at one end and gradually taper so as to be much narrower at the opposite end. The blades, furthermore, are attached along their ma or length to the inside of the drum on right and left helix segments, for instance, the blade d describes a part of a left hand helix from the point e to the point f, wh le the blade it describes a right hand helix segment from the point g to the point z, where it is attached to the drum. Furthermore, each blade is twisted bout its major The operation is simple: The drum is ro tated continuously in-one direction by any suitable source of power. The mass 0 clothes is caught by the hollow surfaces of one of the blades, for instance, the lower blade in Fig. 2. This carries the clothes up the side of the drum, and by reason of the helical pitch of the blade forces the mass ofclothes toward the small end of the blade, which is the end removed from the observer in Fig. 2. At the same time the twisting dispositiomo-f the blade serves to turn the clothes and thereby agitate them in the water during the end movement. When the clothes reach the remote end of the cylinder and when the blade that carries them is about to pass the highest point reached in the. rotation of the'drum, the clothes drop off from the small-end of the blade into the large end of the other blade, which is substantially at the low point of the drum at this time. a
The same process is repeated when the clothes are forced to the near end of the drum by the blade that now carries them, which is of the oppositepitch. Obviously the clothes are first worked from one end of the cylinder and then dropped from the top of the cylinder to the bottom and then worked to the opposite end of the cylinder and then dropped from top to bottom, in the meantime being turned by the twist in the blades. This operation being continuously=repeated-, it very successfully agitates the clothes inthe water and at the same time the clothes are not tangled for as fast as one smaller at blade twists them in one direction the oppos' e blade reverses the twisting so as to untan le them.
Vlhat I claim is: 1. In a washing machine,
11 a washing machine, a drum arranged clothes and for a cleansing provided with blades therethan the other. a drum arranged clothes and f rum and larger at one end In a washing machine,
having blades secured to e. inside arranged on oppositely-directed helixes on the interior of the drum and holow on one side and convex on the other and one end than at the other.
In a washing machine, a drum arran for containing clothes and f Or a cleansing liquid, said han at one blade being the small end of 5 liquid, said interior of the 3' than at the 0th drum having blades secured to concave on the other and smaller at 7 opposite endof the drum and conversely.
with the large end of the blades.
In a washin machine, a drum arran ed for containing. c othes and for a cleansing drumhaving blades secured to t e interior of the drum on oppositely-directed helixes and the said blades twisting about eir major axes.
In a washin machine, a drum arranged for containing clothes and fora cleans liquid, said drum having blades secured to t e interior of the drum on oppositely-directed helixes, the said blades each twistin from one end to the other, the two blades twisting in opposite directions. 1 In a washing machine, and in a drum thereof, a blade or paddle secured to the drum on a around the drum.
