This results in the curtains loading door opening 4 cencentric therewith. not unduly obstructing each other, and in an The door opening 4 is .usually provided with 9.. even distribution of the fluid throughout the' suitable door frame structure I! and the header length of the drum. The projecting or rinsing 6 seats, as at l3, on the door frame II. The door 55 and in the combinations and constructions hereoppostie end of the drum, the axle 3 being jouropening 4 is alined with a door opening, not
shown, in the wall of the outer casing and is spectively, these conduits thrusting at their ends at I 5, l6, against the headers. The header 5 is formed with outwardly extending peripheral arms 6 formed with nipples 6' extending into the ends of the conduits and also extending at 6 through openings in the head of the drum. The fluid enters the header 6 through the nipples and arms 6.
The drum or hydro-wheel is usually provided with inwardly extending hollow ribs l8, these ordinarily performing the function of tumbling the clothes during movement of the drum about its axis or of carrying the clothes during the rotation upwardly from the lower part of the drum to the upper part and letting them fall again to the lower part.
The conduits H are located within the hollow ribs, as shown. The peripheral walls or barrel of the drum, as well as the ribs I8, are perforated in the usual manner.
Each end wall or head of the drum is provided with jet openings communicating with the headers 5, 6, respectively, the jet openings being arranged in annular series concentric with the axis of the drum and the radius of one of the series being different fromsthat of the other series, so that the jets or cylindrical curtains formed by the jets do not unduly interfere with each other. As here shown, the annular series of jet openings 20 leading from the header 5 are of less radius than the annular series of jet openings 2| leading from the header 6. The headers 5, 6 are secured together or are held assembled to the drum by tie-bolts 22 extending through the headers and through the conduits l4. Owing to this construction, thetie-bolts clamp the headers against the heads of the drum and the ends of the conduits I4 and stiffen the entire drum structure, as wellas hold the headers and the conduits inassembled position.
In operation,-while the drum is moving about its axis to tumble the clothes, the rinsing fluid passes from the supply pipe 1 into the hollow axle 3, header 5, conduits l4, into the header 6, and is projected'through the jet openings 20 leading from the header 5 and also through the jet openings 2| leading from the header 6, there-- by forming two cylindrical curtains of different diameters, so that one passes or telescopes within .the other. This results in an even distribution of the rinsing fluid, particularly in relatively long drums.
-curtains,substantially concentricwith the axis of the drum, the projecting points at the ends of the drum being arranged in an annular series and the annular series at one end being of great-' er radius than that at the other end.
2. In a washing machine of the type having an outer casing and a perforated clothes container drum located in the casing to rotate about a horizontally extending axis, the drum having an axle at one end and a central loading door at the other end, thecombination of means for projecting a.
fluid into the drum in a directionlengthwiseni' the axis of the drum provided with the loading door, said means comprising an annular header surrounding the loading door opening and provided with an annular series of jet openings directed into the drum.
3. In a washing machine, the combination, of an outer casing and a perforated clothes container drum mounted in the casing to rotate about a horizontally extending axis, headers mounted on opposite ends of the drum and rotatable therewith and having jet-openings sp aced radially from the axis'of the drum and directed into the drum, imperforate conduits extending lengthwise of, and rotatable with, the drum and connecting the headers, one of the headers being connected to a fluid supply.
4. In a washing machine, the combination of an outer casing and a perforated clothes container drum mounted in the casing to rotate about a horizontally extending axis, the drum having an axle at one end, and a loading door opening at its other end, headers mounted on opposite ends of the drum, one header surrounding the loading door opening, the headers having an annular series of jet openings directed into the drum, conduits extending lengthwise of the drum and connecting the headers, one of the headers being connected tov a fluid supply.
5. A washing machine comprising an outer casing and a perforated clothes container drum mounted in the casing to rotate about a horizontally extending axis, the drum having hollow ribs extending inwardly from the peripheral wall thereof, headers mounted on the opposite end walls of the drum, each having an annular series of jet openings directed into the drum, one header being connected to a fluid supply, conduits located in the hollow ribs and extending between the headers, and tie-rods connecting the headers and extending through said conduits.
6. A washing machine comprising an outer casing and a perforated clothes container drum mounted in the casing to rotate about a horizontally extending axis, headers mounted on the outer sides of the end walls of the drum and having jet openings directed horizontally into the drum, conduits extending lengthwise of thedrum and spaced radially from the axis thereof, and
connecting the headers, one header communicating with a fluid supply, and tie-rods connecting the headers and extending through the conduits. 7. A washing machine comprising an outer casing and a perforated clothes container drum mounted in the casing to rotate about a hori-,
zontally extending axis, the drum having an axle at one end and an axial loading door opening at the other end, headers mounted on the outer sides of the end walls of the drum and having jet openings directed horizontally into the drum, one of the headers surrounding the loading door opening, conduits extending lengthwise of the drum and spaced radially from the axis thereof and connecting the headers, the header at the axle end of the drum communicating with a 'fluid supply, and tie-rods connecting the headers and extending through the conduits.
. 8. In a: washing machine of the type having an outercasing and 'a perforated clothes container drum located in the casing to rotate about a horizontally extending axis, the drum having an axle at one end and ,a. central loading door at the other end, the latter end being provided with an annular series. of jet openings in the end wall curtains. the projecting points at the ends of the drum being arranged in annular series and the projecting points at'one end of the drum being arranged out of alinement with those at the other end, whereby the cylindrical curtain projected from one end of the drum does not encounter the curtain projected from the other end of the drum.
