DOMESTIC LAUNDRY MACHINE Filed May 12, 1959 2 Sheets-Sheet 2 -.a0 in United States Patent ()fifice 3,010,617 DOMESTIC LAUNDRY MACHINE Frederick R. Sibbald, Norwood Green, Southall, England, assignor to The Hoover Company, North Canton, Ohio, a corporation of Ohio Filed May 12, 1959, Ser. No. 812,707 8 Claims. (Cl. 222383) The present invention relates to domestic laundry machines and more particularly to removing liquid from the machine.

An object of the invention is to provide a domestic laundry machine having an outer casing, a pump to deliver liquid from the machine through a conduit extending from the pump out through a guide sleeve adjacent the top of the machine, the conduit being at least partly of flexible material and of such a length as to permit it to be drawn through the sleeve to raise its end from a retracted position within the confines of the casing to a working position in which part of it extends above the casing.

Another object is to provide a domestic laundry machine having a pump to deliver liquid from the machine through a conduit which includes three portions, a substantially rigid middle portion extending vertically through a guide sleeve, an upper discharge portion extending generally horizontally from the upper end of the middle portion, and a lower flexible portion connecting the middle portion to the pump and of such length and flexibility as to allow the rigid middle portion to slide longitudinally in its guide sleeve to allow the upper discharge portion to be raised and lowered as well as allowing the middle and upper portions to be turned about a vertical axis in the guide sleeve. The upper discharge portion is moved between a retracted position within the confines of the machine and to a working position in which it extends above and projects laterally from the machine.

A further object is to provide a domestic laundry machine wherein the guide sleeve is mounted in a platform surrounding the top of a container for clothes and spaced below a cover, and the upper discharge portion of a conduit is movable down to a retracted position between the platform and the cover and lies in a trough in its retracted position, the platform forming the bottom of the trough.

Other objects and advantages of the invention will become apparent from the following description and drawings, wherein:

FIGURE 1 is a side elevation, partly in section, of a domestic spin drying machine for clothes and showing the liquid discharge conduit in retracted inoperative position,

FIGURE 2 is a top plan view, with the cover removed,

FIGURE 3 is a broken elevational view, partly in section, showing the liquid discharge conduit projecting laterally from the machine for conveying liquid to a tub or sink, and

FIGURE 4 is a section along the line 44 in FIG- URE 2.

The embodiment of the invention herein disclosed comprises a spin drier having a casing within which is mounted a container 11 and an inner rotating basket 12 driven by a vertical shaft 13 connected through a pulley 14 and belt 15 to a pulley 16 supported on a shaft 17 of an electric motor 18. The container 11 surrounds the spin basket 12 and is water-tight except for an outlet 19 at its lower end which is connected by a flexible pipe 29 to a scavenging pump 21 driven through a pulley 22 and belt 23 connected to a pulley 24 on the motor shaft 17.

3,010,617 Patented Nov. 28, 1961 Extending from the outlet 25 of the scavenging pump 21 is a flexible rubber hose generally indicated at 26 which is formed in three sections. These comprise a horizontal section 27 extending away from the pump towards the left-hand side 28 of the casing 10 and which doubles back at 29 into a second horizontal section 30 extending between the pump 21 and the outer casing 10. The section 30 gently curves at 31 to merge into a vertical section 32 which extends to roughly half way up the side of the casing 10 between the latter and the spin drier container 11. The upper end of the hose is connected by a clip 33 to the lower end of a rigid vertical pipe 34 which extends to the top of the casing 10 and through a sleeve or guide 35 secured between the top of the container 11 and the casing 10. The pipe section 34 is made of heat stabilized polystyrene.

Extending at right angles from the top of the rigid pipe 34 is a discharge tube 36. In the position shown in FIGURES l and 2 the discharge tube 36 is lying in a seat or trough 37 extending along a platform 38 disposed between the container 11 and the outer casing 10. The bottom of the trough 37 is formed in the platform 38 which is cast inte ral with the sleeve or guide 35. The discharge tube 36 comprises a molding of suitable plastic such as heat stabilized polystyrene having a portion 39 at one end for connection to the rigid vertical pipe 34. The remainder of the discharge tube 36 is of generally rectangular section with a downward extension at its free end to provide a downwardly directed outlet 40. The discharge tube 36 is conveniently molded, the two end portions and the rectangular portion being molded with an open top which is closed by a fiat plate 41 secured to the remainder of the tube by a suitable adhesive.

The discharge tube 36 lies within the trough 38 at the top of the machine in a storage position and is enclosed by a cover 42 for the machine. The tube '36 may be lifted from the trough 38 by inserting a finger underneath an overhanging extension 43 of the top plate of the tube.

The length of the flexible hose 26 connecting the pump 21 to the rigid vertical pipe 34 is such that the latter is drawn through the sleeve 35 until the discharge tube 36 is raised above the top of the machine. The discharge tube 36 is then rotated on the vertical axis of the guide sleeve 35 from within the confines of the machine to the laterally projecting operative position shown in FIGURE 3. When the discharge tube 36 is in its operative position the down turned outlet 40 is hooked over the edge 44 of a waste tub or sink 45 to direct the liquid removed by the pump 21 from the container 11 into the tub 45.

When the discharge tube 36 is returned to its inoperative position over or into the trough 38 the vertical rigid pipe 34 is rotated within its sleeve 35 and places a twist in the flexible hose as shown by the curved lines 46 in FIGURE 1. Thus when the discharge tube 36 is raised from the trough '38 the twist in the flexible hose biases the discharge tube 36 laterally "outwardly from the machine to its operative position so that the downturned end 40 can be hooked over the edge 44 of the sink 45. It will be appreciated that a suitable frictional engagement between the rigid vertical pipe 34 and the sleeve 35 is provided to hold the pipe at the desired raised position. This frictional engagement also prevents any liquid passing down through the sleeve 35.

While I have shown and described but one embodiment of my invention, it is to be understood that this embodiment is to be taken as illustrative only and not in a limiting sense. I do not wish to be limited to the particular structure shown and described but to include all equivalent variations except as limited by the scope of the claims.
