,My invention relates to laundry apparatus and has for an object to provide improved apparatus of this kind.

'A further object of my invention is to provide improved means for admitting a detergent .to the washing chamber of a laundry machine.

Itis a further object of the invention to provide improved ,soap admission provisions for a washer of 'thetype having a perforate basket ro.

tatable about 'a generally horizontal axis within a tub wherein the soapis deposited directly in v the basket and is prevented from passing to the drain of the tub in an undissolved condition.

A still further objector the invention is to provide improved non-corrosive means for admitting soap to a water-tight washing chamber and for providing venting of the chamber.

These and other objects are effected by my invention as will be apparent from the following descriptionand claims taken in accordance with the accompanying drawings, forming a part oi this application, in which: i

Fig. l is a vertical sectional view takenthroug'h one form 01' washer having my invention applied thereto", certain portions of the view being shown in elevation for the sake of clearness;

Fig. 2 is an enlarged front view of the door of the tub shown inFig. 1; and,

Figs. 3 and 4 are sectional views takenalong the'respective lines IIII1I and Iv -IV of Fig.2.

Reference will now be had to the drawings wherein I have shown my invention applied to a laundry machine of the general type disclosed and claimed inmy copending application, Serial No.

1 203,804, filed Apri1.23, 1938, and assigned to the assignee of the present application. The laundry machine includes a tub structure It, generally of frusto-conical configuration. and having its axis disposed at an acute angle to the vertical so that its end' wall 'II of major dimension is faced upwardly and forwardly. v

A basket structure I! of irus'to-conical formation is disposed subst'antially-in-coaxiai relation within the basket II and has an access opening I: iormed in its end wall .lliofrnaior dimen- I mean one which extends either directly horizontal or is inclined with respect to the horizontal up to 60 therefrom.

Rotation of the basket l2 within the tub vIll at relatively low speed during washing periods and at relatively high speed during fluid-extractirig periods is effected by a motor l6 suspended by means of a bracket structure II on the underside of the tub and belted, as shown at N, to a twospeed mechanism, generally indicated at l!, and carried by the tub structure Ill. The two-speed fmechanismlQ may be of a well-understood construction and is adjustable to provide the low speed for the basket l2 during washing periods and to drive the same at high speed during the centrifuging periods. A two-speed mechanism of the type shown at I! combined with a tub of generally frusto-conical configuration is disclosed and claimed in my, copending application, Serial No. 305,512, filed November 21, 1939, and assigned to the assignee of the present application.

From the foregoing it will-be apparent that the tub ID, the motor l8 and the two-speed mechanism I! define major elements of a I unitary structure which may be supported within an enclosing 2| in any well-understood manner. Preferably the support for the unitary structure is flexible so that it is free to vibrate in all modes within the casing II and without imparting ob- Jectionable vibrations'to the casing. The flexible support may include a plurality-of tension springs 22 which are suitably attached to the unitary structureand which are carried by the casing! I A flexible support of the general type shown herein having vibration damping provisions is disclosed and claimed in my copending application.

Serial No. 228,853, filed August 26, 1938, and also in the copending application of Frank Breckenridge et al., Serial No, 303,202, filed November '1, 1939, both of which applications are assigned to the assignee of the present application.

sion. The access opening it of the basket II registers with an access opening ll formed in the end wall n of the tub structure.

The laundry apparatus disclosed'isof-the inclined axistype but it willbe understood that this iormof washer is shown byway 0! example and-that other types of washing apparatus new ing an axis of rotation extending generally hori- Tzon'tal maybe ecnst'ructedin accordance with a horizontal axis.

(not shown) through a flexible conduit 23 which' terminates in a nozzle structure 24 carried by the tub II, the nomle It being so disposed that it directs water through the access opening ll of the basket. In this connection it will be understood that the basket is perforate. a number of being shown at II, so-that the water flows through the be m and into the tub.

being preferably driven by the motor 16. Flow of water from the drain 26 to the inlet of the of the water contained in the tub III is indicated by the broken line A" inFig. 1.

During washing periods, the basket I! is rortated at relatively low speed, or approximately 52 R. P. M., by means of the two-speed mechanism l9, and the fabrics are agitated in the The method of agitating the fabrics forms no part of the present invention so that it will notbe described other than to say that a plurality of inwardly-extending and circumferentially-spaced vanes 32 are provided within the basket l2 which elevate and drop the fabrics during the washing operation. The specific vane and basket structure which I have shown is disclosed and claimed in the copending application of Stuart R. Baird, Serial No. 268,103, filed April 15, 1939, and assigned to the assignee of the present application. p

As set forth heretofore, the unitary washing and spinning structure is enclosed by a casing 2| which includes a front wall 33, the upper portion of which is inclined as shown at 34, the inclined portion 34 of the front wall being disposed in a plane normal to the axis of the tub and basket. An opening 35 is provided in the front wall portion 34, said opening being closed by a movable cover 36. As shown, the cover 36 is pivoted at 31 to the casing 2| and may be swung to a substantially horizontal position for providing a work shelf at the front of the washer during its operating periods, as disclosed and claimed in the copending application of William J. Russell, Serial No. 314,577, filed January 19, 1940, and assigned to the assignee of the present application. During inactive periods, the door 36 is swung to its closed position for completely enclosing the working mechanism.

During operatingperiods of the washer, the access opening I of the tub structure It! is closed by a door, generally shown at 36, that is gasketed and latched shut so that a substantially water-tight connection is defined by the perimeter of the 'door 33 and the tub As best shown in Figs. 2 to 4, inclusive, the door structure 38 includes a. generally annular rim 39, one side of which is formed to define a bearing 4| for a movable latch member 42, the latter being swung to itslatched and unlatched positions by means of a handle 43. The movable latch 42 cooperates with the stationary catch 44 suitably secured to the end wall ll of the tub. The opposite side of the annular rim 39 is formed to define a hinge 45, the stationary portions of which are secured to the front wall I I of the tub. As the specific form of latch and hinge structures form no part of'the present invention, a further description of the same is deemed unnecessary. It will be understood that the overall length of the door structure 33 is less than the width of the opening 35 formed in the casing so that the door may be swung upwardlythrough the opening 35 when access to the basket is desired.

The rim 3! is embossed to form a substantially annular wall 46 extending axially :and which terminates at its inner'end in'an inwardly-extending flange 41. The central portion of the door is defined by a glass partition 46 which is substantially flat except as hereinafter described.

The glass partition 48 is positioned by the inwardly-extending flange 41 and by means of an arcuate spring member 49 which is sprung within a seat 5| formed in the axially-extending wall portion 46 of the rim. A suitable gasket 52, annular in configuration, is arranged on the exterior of the wall member 46 and is engageable with-the perimeter of the tub opening l5 so that a water-tight seal isdefined at this point.

In accordance with my invention, a non-corrosive chute or passage is disposed in registry with theacces's opening l3 of the gasket for the admission of a detergent directly to the basket. The soap passageor chute is shown at 53 and is enclosed within an offset portion formed in the glass partition 48. The chute 53 is defined by laterally-spacing walls 54, generally triangular in shape, and a sloping wall 55 which connects the outer margins of the triangular walls 54 and which is disposed at an angle to the plane of the glass partition 48, as best shown in Fig. 4. Both the triangular-shaped walls 54 and the sloping walls 55 are preferably integral with theglass partition 48.

A portion of the rim 39 is embossed to define laterally-spaced side walls 56 and a. front wall 5'! connecting the same, the front'wall 51 being disposed above an intermediate portion of the chute '53, as best shown in Fig. 4, and the spaced side walls 56 extending upwardly in the planes of the spaced walls 54 of the chute 53. An elongated opening or seat 58 is formed in the front wall 51 for receiving a lid or cover 59 for the chute 53. The lid 59 engages the outer ends of the triangular walls 54 and the sloping wall 55 and defines a closure for the chute 53. Th inner margin of the lid 69 is enlarged to provide a bead .6I that is generally cylindrical in cross-section and which is seated within the seat or opening 58. A hinge is therefore defined by the seat 58 and bead 6| about which the lid 59 is movable. The lid 59 is biased toward its closed position by torsional springs 62, one end of each being hooked within openings in the lid, as shown at 63, and the other ends of which engage a portion of the wall 51, as shown at The springs 62 not only function to continually bias the lid 59 closed but, because'of their hooked connections, as shown at 63 and 64, to the lid 59 and the wall 51, the springs 62 maintain the cylindrical portion 6| of the lid seated within the opening 58. A suitable han-' di 65 projects from the lid 59 for'facilitating the opening movement thereof.

When' the washer is to be operated, the lid 36 is swung to its lowered or horizontal position and the door 38 swung upwardly through the opening 35. The fabrics to be treated are then deposited in the basket l2 and the door 38 latched in its closed position. Water is admitted to the tub and basket through they nozzle 24 until the level rises to the line indicated at A in Fig. 1. If it is desired to prewash or soak the clothes, slow speed operation of the basket is initiated during which time the clothes are tumbled in the fresh water for loosening the soils therein.

The washing operation is initiated by admitting soap to the wash water which is effected by pouring the soap through the chute 53 after Opposite the access opening 13 of the basket and above but adJacent to the level of the waterin the. basket. tive the basket The ,chute is so disposed relathat the soap poured therein solution.

' water.

clear water is splashed over the soap chute walls contained in the basket. Substantially none of the soap. admitted .at this time can enter the intervening space between the basket and the tub without first passing through the body of water contained within the basket. Accordingly,

the passage of soap particles in an undissolved form directly to the drain 2' is precluded. Any soap which may cling to the walls ofthe chute will be washed therefrom by the splashing water within the basket so that the walls of the chute. are maintained clear of soap at all times.

The soap is thoroughly dissolved in the agitated body of water within the basket so that a very efllcient washing solution is obtained. I consider this an important feature of my invention as, in prior structures of which I am aware, the soap is directed by the soap admission chute in such manner that a substantial quantity thereof is first deposited in the intervening passage between the basket and the tub for dis- In these prior art structures, however, a substantial quantity of the soap in undissolved form may find its way to the drain passage and in time collects therein so that clogging of the drain may occur. Furthermore, there is less agitation of the water in the intervening passage referred to heretofore so that the dissolving of the soap is slower and the Process of quickly producing suds within the basket is retarded. In this connection, it will be also noted that particles of wet soap may be retained ina chute which communicates with the space intervening between the basket and the tub and therefore corrosion of the chute walls is effected.

Afterthe washing operation is completed, the

soapy vltiated water is discharged from the tub through theopening 26 by means of the motordriven pump 28. The fabrics may then be rinsed by admitting clear rinse water to the tub through the nozzle 24 and tumbling the fabrics in the During the rinsing operation, the clean so that they are thoroughly flushed clean of any soap collections. The rinse water is then discharged and the basket I! is rotated at a relatively high speed of, for example, 550 R. P. M.

for centrifuging the water from the fabrics.

Subsequent to the centrifuging operation, the

door 38 .may be opened and the damp-dried fabrics removed from the basket.

A further feature of my; invention resides in forming the soap chute 53 of a vitreous material so that any collection of soap particles or soap film therein will not corrode the walls of thechute. Furthermore, by arranging the soap chute 53 within the door structure, the cost of producing laundry apparatus having the soap admission features is substantially reduced as the glazed portion of the door usually employed and the .rim for supporting the same may be readily modified to define the soap admission opening as described heretofore. v

It will be apparent from the description of the specific embodiment shown that the soap chute I3 is elevated above a portion of the access opening ll of the basket so that the material admitted therethrough drops directly by gravity into the basket. When applied to washers of the horizontal axis type-or having an axis substantially horizontalgthe sloped wall member 55 of the chute is effective to direct the soap inwardly through the access opening of the basket and without permitting any material quantity thereof to pass to the intervening space between therefrom. I. while permitting venting prevents water from being splashed from the tub during normal operation. Venting of the tub in a washer of the type shown having a water-tight access door is also desirable in order to prevent excessive pressures from building up in the tub in the event that sufliclent water is admitted to the tub to fill the same and thereby subject the tub structure' to the full pressure of the water supply. Obviously, the relatively light spring associated with the lid 59 would permit opening of the lid if the latter is subjected to a slight pressure within the tub-in excess of atmospheric pressure,

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and 'I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims. What I claimis:
