WASHENG MCHENE.

Application filed February 7, 1923. Serial No. 617,502.

To @ZZ fic/7mm 'it may concern:

Be it lrnown that l, HOWARD VnnBURToN, acitizen ofthe United States, residing at Hamilton, in the Province of Ontario, Dominion of Canada, have invented certain new and useful improvements in lashing llachines, of which the following isa speciiication.

The present invention relates to washing machines having a revolving cylinder mounted in a tub or casing.

Tie main object of the invention is to furnish a cylinder of this character, which has its interior constructed in a peculiar manner in order to produce better work than inordinary machines of this class in a shorter time. For this purpose the cylinder has corrugated inner 'surface and radial partitions in tle form of pockets. The function of the cylinder is now to force the clothes to be washed through the water by means of these pockets at the same time rubbing them against the corrugations furnished around the circumference of the cylinder as well as on these radial partitions. The clothing is alternately forced into 'the water and lifted out of the same in this manner imitating the operation of washing clothes by hand but without tearing or iujuring the same.

ln the accompanying drawings one embodiment of the invention is illustrated; and

Figure 1 is a vertical axial section of the washing machine;

Figure 2 is a transverse section along line 2--2 of Figure 1; and

Figure 8 is a transverse section of the cover for the revolving cylinder.

The washing machine consists of the tub or casing 10 of cylindrical or semi-cylindrical shape deposited with its anis in horizontal direction in the usual manner and being Vclosed at each end by flat boards or side Vplates 11. The open top of the casing is closed by means of a lid 12 preferably hinged alone one edge of the casing as at 9. This opening at the top of the casing is naturally large enough to permit the insertion or removal of the revolving drum 13. The casing is supported in the usual manner on a stand 1d forming a rigid construction therewith, The end plates 11 of the casing each have a centrally located bearing 15 for the shaft 16 revolvably mounted therein and one end of the shaft is flattened or of square cross section adapted to receive a crank or handle 16, if hand power is used to revolve the drum, or a pulley or gear wheel 36in case motive power is used, an electric motor for instance.

The cylinderor drum 13 consists of two flat end plates or boards 19 which are rigidly connectedwith the shaft 16 so as to par* take of its rotation. These end plates 19 are circular with the exception of a segment cut off 'at one side, and the cover 2i) has similar side plates 21 with the exact size and shape Vof the cut away segments of the side plates 19 so that the latter and the end plates of the cover together form complete circular disks when assembled.

r The two end plates 19 of the drum are connected by means of a plurality of rods or ribs 22, which are spaced from each other to `form longitudinal openings at intervals along the cylindrical side of the drum. These rods 22 are preferably made of cylindrical bars split in two along their axes and placed with their thus attened sides even with the outer periphery of the disks or end plates 19. The rounded portion of the rods 22 are all facing inwards in the cylinder, so that in this manner a corrugated inner surface is formed in the cylinder with alternating or interrupting spaces 2B, as best seen in Figure V2.

rl`he cover is similarly provided with rods or ribs 24 fastened along the outer periphery of the end plates 21, as seen in figure 3.

To the inside of each of the disks or end plates 19 of the drum and symmetrically on the center line running perpendicularly .io the straight segmental edge 25 thereof, is rigidly secured a wedge 26, see Figures 1 and 2. The blunt edge of the wedge coincides with the outer periphery of the corresponding disk 19, while its apex extends beyond the longitudinal axis of the shaft 16 in the drum 13. Against the straight sides of the wedges 26 and connecting the two disks 19 are secured ribs or rods 27 of the same character as the ribs or rods 22 and 24 and these ribs 27 are spaced apart substantially the same distance as the previously described ribs.

The cover 2O is also provided with a pair of wedges 28 rigidly secured centrally on the end plates 21, as seen in Figures 2 and 3, and adapted to engage, by means of notches 29 furnished at the apices of the wedges 28,

the sharp apices 30 of the opposing wedges 26. These notches 29 are preferably formed in metal shoes 32 secured at the apex of each wedge 28. The sides of these wedges 28 are also furnished with ribs 31 of the same cross section as the already described ribs 2 2, 24 and 27, and spaced substantially the same distance apart as the former ribs. The cover 20 is held in position on the drum 13 by means of swiveled clamps 32.

It will now be evident that, when the cover 20 is secured to the drum 13 by means of the clamps 32, there are formed two compartments A and B, one on each side of the opposing wedges 26 and 28 and their ribs 27 and 31. As, however, these ribs as well as the peripheral ribs 22 and 24C are spaced apart, the water in the casing lO has free access to both compartments. During the operation of the washing machine the clothes to be washed are deposited in these two compartments A and B and the lid attached. It will now be evident that during the revolution of the shaft 16, together with the drum 13, the clothes will be alternately dipped into the water and carried up out of same by means of the central ribs attached to wedges 26 and 28, and gently rubbed against the corrugated surface formed by these ribs as well as the peripheral ones. ln this manner a thorough rubbing and cleaning of the clothes is performed, imitating the rubbing of clothes on a corrugated wash board and the dipping of them in water and subsequent wringing of them.

At the lowermost part of the casing 10 is formed a pocket 33 intended to collect the sediment from the water, and a drain cock 34 is provided in this pocket for emptying the water contained therein after each washmfr.

t:t is evident that the cross section of the ribs does not necessarily need to be semi-circular but may be semi-elliptical or even flat sided as long as a corrugated surface is provided in the drum.

Having thus described the invention what is claimed as new is:

l. A washing machine comprising a casing, a revolvable shaft mounted in said casing, a drum rigidly secured on said shaft and having a plurality of longitudinal ribs extending from end to end thereof, said ribs being spaced apart and having their inward turned sides of convex formation providing a corrugated peripheral surface in the drum, and other longitudinal ribs of similar formation in said drum arranged along substantially diametrical planes therein and having their convex surfaces facing the convex surfaces of said first ribs, said diametrical planes intersecting each other and said drum being divided into two mating segmental'parts, the smaller of which forms a cover for the drum, and opposing wedge shaped supporting members or said other ribs secured respectively in said mating segmental parts of the drum.

2. A washing machine comprising a casing, a revolvable shaft mounted in said casing, a drum rigidly secured on said shaft and having a plurality of longitudinal ribs extending` from end to end thereof, said ribs being spaced apart and having their inward turned sides of convex formation providing a corrugated peripheral surface in the drum, and other longitudinal ribs of similar formation in said drum arranged along substantially diametrical planes therein and having their convex surfaces facing the convex surfaces of said first ribs, said diametrical planes intersecting each other, and Said drum being divided into twoV mating segmental parts, the smaller of which forms a cover for the drum, and wedge shaped supporting members for said other ribs, two of said supporting members being secured in the drum portion and the other members being secured in said cover portion.

3. A washing machine comprising a casing, a revolvable shaft mounted in said casing, a drum rigidly secured on said shaft and having a plurality of longitudinal ribs extending from end to end thereof, said ribs being spaced apart and having their inward turned sides of convex formation providing a corrugated peripheral surface in the drum, and other longitudinal ribs of similar formation in said drum arranged along substantially diametrical planes therein and having their convex surfaces facing the convex surfaces of said first ribs, said diametrical planes intersecting each other, and said drum being divided into two mating segmental parts, the smaller of which forms a coverfor the drum, and wedge shaped supporting members for said other ribs, two of said supporting members being secured in the drum portion, the otherrmembers being secured in said cover portion, and interengaging elements at the adjacent points of said members.

In testimony whereof I aHix my signature. HOWARD l/VARBURTON. [n s]
