WASHING MACHINE.

Application filed March 16, 1926. Serial No. 95,027;

sudsor cleansing solution is caused to cir- I culate through the interior of the cylinder in an effective manner as the cylinder is W rotated.

Further objects of the invention are to provide a washing machine cylinder which V is comparatively simple and inexpensive in its construction, which has rigid side walls and will not easily warp or lose its shape,

and which can be handled in the same manner as the conventional cylinders which are in common use;

While one particular embodiment of the invention is shown and described -in detail it will be understood thatmany modifications and changes can be made in the details of construction without departing from the spirit of the invention.

i For a full understanding of the invention reference is tobe had to the following de scription and accompanying drawings in which,

view through a washing machine tub and cylinder which are constructed in accordance with the invention.

Figure 2 is a topplan view of the cylinder which has been lifted out of the tub.

Figure 3 is an enlarged sectional view through a portion of the peripheral walls of the tub.

Corresponding and like parts are referred to in the following description and indicated on all of the views of the drawing by like reference characters.

Referring to the drawings, which illustrate one of many possible embodiments of tub, which may be of any conventional construction, being shown as formed with a rounded bottom 1 and as supported by the legs 2. Rotatably mounted within the tub which is adapted to receive and interlock Figure 1 is a transverse vertical sectional the invention, the numeral '1 designates a.

with a correspondingly shaped drive shaft projecting through the end wall of' the tub. Any conventional power means can be used for turning the drive shaft to rotate the cylinder and it is customary in .vashing machines of this type to provide gearing for automatically reversing the direction of rotation of the cylinder after it has been turned in either. direction a predetermined number of revolutions. i

The cylindrical side wall of the cylinder is provided at suitable intervals with longitudinally extending slots 7. Arrangedin each of the slots is a baffle member 8. The battle members are radially disposed and project through the slots 7, being provided at their outer ends with lateral flanges 9 ,which project therefrom in opposite directions and overhang the respective sides of the slots. The flanges are in a spaced relation tothe exterior'of the cylinder and the baffle members 8 are shown as extending the full length of the cylinder. and having their opposite ends secured to the end walls 3 of the cylinder. The cylinder can be conveniently formed fromsheet metal andchannel shaped strips of sheet metal can be used for forming the baffle members 8. The baflle members have a hollow formation and the edge portions of the side walls of the channel members can be bent laterally to provide the flanges 9. The innerends of the baffle members may be formed in this manner so that there are no sharp corners or projections to catch upon and tear the clothes when the washing machine is in operation. I i

In order to provide for placing the clothes in the cylinder and removing them there from, an opening is formed in one side of the cylinder, said opening being normally closed by a door'lO. The door may be secured in position in any suitable manner, although as shown on the drawings, it isprovided at one edge thereof with lugs 11 which extend under the corresponding edge of the opening, the opposite edge of the door being provided with a latch 12 which is rotatable into and out of engagement with the opposite edge 'of the opening. VVhenthe cylinder is formed of sheet metal the edges of the longitudinal slots 7 therein may be returned, as

shown at'13, around stiffening wires 14.

Likewise, the edges of the fianges 9 of the battle members 8 may -be-returned, asiindicated at 15, around stiffening wires 16. The

free edges of the sheet metal parts are thus stiffened and at the same time any sharp edges which might have a tendency to injure the clothes being washed or fingers of the operator are eliminated.

lVhen the cylinder A is mounted in position within the tub 1, as shown by Figure l, the bottom of the cylinder is in a spaced relation to the correspondingly curved bottom of the tub. The tub is partially filled with some suitable cleansing solution such as suds and water, and as the cylinder is rotated in either direction the projecting ends of the baflie members 8 and flanges 9 thereof serve to catch portions of the cleansing fluid and force it to circulate upwardly through the slots 9 into the interior'of the cylinder. The oppositely projecting lateral flanges 9' of the battle members become alternately operative as the cylinder is rotated in opposite directions, and'as the cleansing fluid or solution is forced into the interior or the cylinde r on one side of the bafifle membersS itcan leave the cylinder through the portions of the slots 7 on the opposite sides of the battle members 8. An effective circulation of the cleansing fluid or solution is thus maintained through the interior of the cylin'der when tlie devi ce is in operation and the portions of the side wall 4 or the cylinder between the slots can be imperforate, thereby enabling it to have a rigid construction, As the cylinder is rotated in either dir-ectionthe flanges 9 of the bafiie members 8 tend to catch the cleansing fluid or solution between the bottom of the tub and cylinder and force it into the cylinder through the portions of the slots 7 on one side of the battle members 8. At the same time portions of the cleansing fluid already within the cylinder may leave the same through the portions of the slots 7 on the opposite side of the baflie members 8. In this manner a constant and efiective circulation of the cleansing fluid is kept up through the interior of the cylinder, with the result that the clothes or fabric within the cylinder is quickly and efiectively cleansed.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is, i

A washing machine cylinder having longitudinalslots in the curved sidewalls thereof, hollow channel shaped baffles extending longitudinally of the cylinder on the interior thereon and arranged with the sides thereof disposed in a substantially radial position and projecting outwardly throughthe slots in a spaced relation to the edges of the slots, and comparatively short oppositely project ing flanges at the outer ends of the sides of the ob annel shaped b a'li'les said flanges being in a spaced and substantially parallel rela tion tothe exterior of the cylinder and cooperating 'with the outwardly projecting ends of the bafides to forcibly direct the cleansing fluid into the interior of the'cylinder when the cylinder is rotated in either direction. I

Intestimony whereof I'affiX my signature. i
