LAUNDRY-CONFINING DEVICE FOR SPINNERS F LAUNDRY MACHINES.

Application filed September 1, 1925. Serial No. 53,811.

The invention relates to a laundry machine of the type having a receptacle which will hold liquid during the washing period and which will allow the liquid to be discharged therefrom during the drying period when the receptacle is rotated at sufficient speed.

In receptacles of the imperforate type part of the receptacle must be imperforate so that it will hold liquid during the washing period. A guard ring may project inwardly't'rom the top of the outer wall of the receptacle to prevent the clothes or other articles being washed from being forced out of the receptacle during washing. Since the guard ring will act as a trap for the liquid when the receptacle is rotated during drying, some sort of dis charge portion must be providedwhich will allow the liquid to be thrown from the receptacle when it is rotated during drying but will allow the liquid to remain in the receptacle during washlng.

In the type of receptacle in which all of.

the liquid must pass through a discharge portion comprising comparatively few discharge holes during drying as in the imperforate type in which the discharge holes are located near the top, the articles being dried may under certain conditions creep up over the receptacle discharge holes and act as a strainer for the liquid being discharged; If the liquid be dirty, due to the tremendous quantity of liquid passing through the comparatively few discharge holes the articles may become spotty and thereby defeat the primary purpose of the laundry machine. The feature of comparatively few discharge openings and the large volume of liquid passing therethrough is usual in the imperforate type receptacle.

According to the invention confining means are provided which prevent the articles from covering the discharge holes. Theseconfining means may take the form of bosses on the flaring outer wall of the receptacle to keep the articles being dried from creeping up the wall to the discharge holes. Or, the outer wall of the receptacle may be made cylindrical thereby discouraging the tendency for the articles to creep up the walls during drying. Another form may be to provide a perforated liner or screen for retaining the articles thereby p'reventin them from covering the discharge holes urin drying.

Another way 0 practicing the invention may be to provide a receptacle with an imperforate outer wall without discharge holes at the top, the liquid being forced over the top or the said wall during drying, the said top constituting a discharge portion in this modi- 'fication. In order to prevent the articles being dried from bein discharged over the top of the outer wall 0 the receptacle during drying, a perforated inner wall or liner may .be provided to confine the articles, the guard ring being attached to the liner in this modification.

An article confining means such as used according to the invention must not onl prevent the articles from reaching the disc arge portion during drying but it must not trap liquid during drying; it must not be of such shape as to get the articles caught or tangled therein; and it must be easy to clean. Various other objects and advanta es of the invention will be obvious from the ollowing particular description of forms of mechanism thereofembodying the invention, in which Fig. 1 is a side elevation partly in section showing an approved type of laundry machine equipped with an arrangement according to the invention; and

Figs. 2, 3, 4 and 5 represent modifications, each .figure showing partially in section an elevation of a half of a receptacle.

In the following description and in the claims parts will be identified by specific names for convenience, but they are intended to be as generic in their application to similar parts as the art will permit.

Referring to the drawing and particularl to Fig. 1, the laundry machine shown, whic is taken merely for the purpose of illustration,

comprises a tank 1 with a receptacle 2 mountcomprising preferably a body 5 having an upwardly extending and slightly flaring annular wall 7 whose lower end may run into a bottom 8 extending inwardly and slightly upwardly from the lower end of the wall to the hub 3. In order to reinforce the mounting of the body on the hub a strengthening plate 6 may be provided which may be secured to the hub 3 and to the bottom 8 near its outer edge in any desired manner. The upper edge of the bod may he provided with an inwardly and slig itly upwardly extending guard ring 10 preferably secured to the wall 7 by means of a lap joint 12. The receptacle is imperforate and is provided with a plurality of discharge openings 13 located near the top thereof and preferably extending through the lap omt 12.

When the receptacle is rotated for drying, the liquid will be thrown to the outer wall 7 whence it will creep up the outer wall and out throu h the discharge openings 13 by centrifugal orce. In order to prevent the articles to be dried from also creeping up the said wall which may occur under certain conditions with the above mentioned undesirable results, a plurality of bosses 14 may be provided on the inner surface of the annular wall 7 spaced from each other and a short distance below the discharge openings 13. These bosses may be made in any desirable way but for purposes of illustration they are shown as having been pressed inwardly from the wall 7 of the receptacle. free to creep up the side wall 7 to the discharge openings 13 between the bosses 14 and that there is no possibility of any of the liquid being trapped. The bosses will effectively prevent the clothes from reaching the discharge Openings and there is no possibility of the clothes becoming tangled or caught in the bosses.

Referring now to Fig. 2 a modification is shown which Will also accomplish the desired purpose. In this construction the wall 20 of the body is cylindrical instead of flaring, a guard ring 10 preferably being secured to the upper edge of the wall in the same manner as in Fig. 1. Due'to the cylindrical shape of the side wall there will be practically no tendency for the articles to creep up the side wall during drying, the liquid having no difiiculty in creeping up the side wall and through the discharge openings 13 on account of its nature.

In Fig. 3- the receptacle may comprise a body 5 and a guard ring 10. The guard ring 10 in this figure may be detachable from the body 5 to allow the removal of a perforated liner 30 extending up above the discharge openings 13. It will be seen that this perforated liner accomplishes the same results as the bosses in Fig. 1, namely, that of preventing the articles from covering the discharge openings13 and acting as a strainer for the liquid.

In Fig. 4 the receptacle may comprise a It will be seen that the liquid is,

body 40 whose wall 41 is perforated, the body having a guard ring 42 secured to the top thereof. Since there are many discharge openings 43 in the wall of the body there is no danger of the clothes becoming spotty due to large vodumes of liquid passing thru a small number of openings. In order to provide a receptacle with imperforate properties which will hold liquid during washing, an annular imperforate wall 44 may be secured to the receptacle body preferably at the turn of the perforated wall 41 into the bottom 45, said wall 44 flaring upwardly and slightly outwardly up a sufficient distance to provide a re ceptacle which will hold the desired amount of liquid during washing.

In Fig. 5 a receptacle is shown comprising a body 50 having an impcrforate wall 51, and a perforated liner 52, the perforate liner having a guard ring 53 secured preferably to the up per edge thereof, the perforated liner and guard ring together being removable from the The above constructions are simple, cheap and efiicient in operation, the parts are few and each may be made rugged so that there is practically no chance of breakage in operation. The provision of clothes confining means for preventingthe clothes from reaching the discharge portion is very important in the laundry machine art, since in the constructions having the discharge holes the clothes will become spotty if allowed to cover these holes during drying and in the constructions Where the liquid is discharged over the top of the outer wall of the receptacle the clothes will be thrown out of the receptacle While I have shown and described andhave pointed out in the annexed claims certain novel features of my invention, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of my invention.

.Having described my invention, I claim: 1. In a clothes washing machine, a receptacle for holding clothes and adapted to be rotated to drive liquid from said clothes, means including a discharge portion whereby said receptacle holds liquid unless it is rotated at suflicient speed to discharge same, and confining means for preventing the clothes from reaching said discharge portion when said receptacle is rotated.
