To all whom t may concern:
Be it known that l, FRANK l?. Bnnrr- LINGER, a citizen of the United States, a resident of Decatur, in ythe county of Macon and State of lllinois, have' invented certain new and useful improvements in Washing- Machines, of which the following is a specication.
Myv invention relates to improvements in washing machines and particularly to the cylinder type of washing machine which is utilized in laundries and households for washing clothes and fabrics of various kinds.
rlhe principal object of this invention is the provision of such a machine wherein the articles will be thoroughly washed and cleaned without the liability of damage thereto.
A *further object is the provision of such a structure whereby the contents of the cylinder are subjected to streams or jets of water or air and water under pressure whereby the articles are ag'tated and thoroughly cleansed ot all foreign substance.
JAnother object is the provision of such a structure wherein the cylinder is formed with receptacles or recessed members which act as pumps or injectors, that is, they operate to force water, and air and water in streams or jets under pressure into the inside of the cylinder against vand through the contents thereof.
A further object is the provision of a cylinder having receptacles which form air and water circulators, said receptacles being so constructed that in the rotation oi the cylinder the water in the washing machine at a certain point will seal the entrance to the receptacle and provide pressure against the air and water therein, tinued rotation of the cylinder streams or jets of air, and water and air will be forced into the cylinder under pressure whereby a thorough washing of the contents is eitected.
'Further objects include improvements in details ci construction and arrangements whereby an eciently operating device is provided. 1
To the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consists in the construction, combination and arrangement of parts hereinafter described and then sought to be dened' in the appended claims, refermeral l in Fig. 2 of so that upon contures or openings ence being had to the accompanying drawing which shows for the purpose of illustrative disclosure a preferred embodiment of my invention, it being expressly understood however that various changes may be made in practice within the scope of the claims without digressing from my inventive idea.
ln the drawings Figure 1 represents a sectional perspective view of a part of a cylinder constructed according to my invention.
Fig. 2 is a sectional and elevational view showing such a cylinder mounted in a tub.
`Fig. 8 is a section of part of a cylinder,
enlarged to better illustrate certain features of my invention.
As stated hereinbcore my invention relates to cylinder washing machines. the nuthe drawings designating the tub and 2 the cylinder itself. This cylinder is rotatably mounted therein by trunnions or otherwise and adapted to be rotated or oscillated in any suitable manner, as well understood by those skilled in the art. These features form no part of this inventionwhich is directed to the construction of the cylinder only.
The cylinder 2 comprises the end plates or members 3 to which are attached or connected the longitudinal members 4 and 5 which complement each other to form the cylindrical surface, as shown. While the details of these members l and 5 are described and shown, it is to be -understood that this is merely one embodiment and that there are various ways of constructing the cylinder to provide the means Jfor the ingress and egress of the air and water as hereinafter described.
The members 4 are each in the 'form of a double walled and curved receptacle, one
end 6 of the member being extended beyond and spaced from the other end 7 thereof to provide an entrance 8 into the receptacle 9 formed between the spaced walls l0 andY il the member being provided with a series o apertures or openings 12 near the juncture ot said walls 10 and l1 at the end of the receptacle opposite the entrance, these aperot air, and air and water the streams or. jets as will into the interior of the cylinder, presently be described.
' The members l andA 5 are shown arranged alternately around the cylinder .and while l2 being adapted to direct` Millrv this is preferable other relative arrangements may be adopted. It is to be noted that the members 4 are also arranged alternately in opposite directions. This is for the purpose of permitting the successful operation of the machine in both directions, as will more fully appear.
Each member 5 has an exterior Wall 13 and the two interior pockets or receptacles 14 which are substantially triangular in shape, the side Walls 15 and 16 thereof being apertured as at 17 to permit the discharge of the Water therethrough. The wall 15 of each pocket 14 is shaped as shown to a proximate in curvature the end portion "6 of the wall 11, as shown and at the junction 18 with wall 13 it is turned slightly outwardly as shown. .The two walls 15 and 16 at their junction 19 are curved to meet the wall 11 of receptacle 4 and apertured as at 20. The space 21 between wall 11 of receptacle 4 and Wall 15 of pocket 14 provides a discharge passage while the space 9 is the inlet passage.
In-operation, the tub is filled with water to a suitable height as indicated as X, Fig. 2, and the cylinder rotated in either direction or'oscillated. It is obvious that some of the receptacles 9 are entirely under water and others entirely out. To facilitate understanding the theory and operation, let us follow the movement of the receptacle marked Y, Fig. 3, about the axis of the cylinder. As shown it"is near its uppermost position and is filled with air only. lt is assumed thatthe cylinder is rotating to the left. Now, when the receptacle Y reaches the level of the water, a small amount of water first passes thereinto from the inside through apertures 12. As the movement of the cylinder continues, t-he entrance 8 to the receptacle is immersed so that it is sealed against the admission or discharge of air and a quantity of air retained therein which is su jected to the increasing pressure of the water back thereof due to the continued rotation of the cylinder. This pressure eventually becomes greater than the internal water pressure and forces the aforesaid small quantity of water out through the apertures 12 in streams or jets, followed by streams or jets of air and water and possibly air alone unt-il the water from the outside passes therethrough, as is well understood. The receptacles 4 therefore in the form shown, act as injectors or pumps causing a forced circulation .through the cylinder. 0f course, it is readily understood that the water inside the cylinder is being discharged therefrom through the apertures 17 and 20 in the pockets on the other side of the cylinder. Therefore a substantially contlnuous .agitation of the contents of the c vlinder* by means of streams or jets of water is nbtained so that the contents are cleansed through and through. The walls of the receptacles and pockets also serve as stops or agitators to assist in this operation.
Attention is alsoJ called to the fact that when the rotation of the cylinder is reversed, a partial vacuum is formed in the receptacles 4 so that the water is siphoned out of the cylinder on one side while being admitted on the other side.
The end members 3 are provided with outwardly and inwardly turned flaps whereby the admission and discharge of t-he water is assisted.
In this machine the articles or clothes are thoroughly agitated so as not to ball or roll up together. This is caused by the action of the streams or jets of air and waover the inner end and at a slight angle to4 a tangent to the cylindrical surface, to provide an entrance whereby as the cylinder is rotated the air in each receptacle will be first sealed and then compressed as the entrance is first immersed and then submerged so as to force streams or jets'of air and air and Water into the cylinder.
2. A washing machine cylinder adapted to be rotatably mounted,`the surface of the cylinder being provided with a plurality of receptacles having apertures leading to. the
inside of the cylinder to admit water thereinto, each receptacle being formed of s aced walls, the free ends of the walls.' eing spaced apart and the outer end extending over the inner end and at a slight angle to a tangent to the cylindrical surface to provide. an entrance whereby as the cylinder is rotated the air in each receptacle will be first sealed and then compressed as the entrance is first immersed and then submerged so as to force streams or jets of air and Water into the cylinder, members located between said receptacles having discharge pockets, one Wall of each discharge pocket approximately paralleling the outer end wall of the receptacle to form discharge passages.
