VICTOR E. ADLAND, OF CHICAGO, ILLINOIS.

WASTE-PREVENTING- CHUTE FOR, CENTRIFUGAL EXTRACTORS.

Application filled September 26, 1921.V Serial No. 503,344.

To all whom t mcy concern Y Be it known that I, VICTOR E. ADLAND, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Waste- Preventing KChute for Centrifugal Extractors; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification. v

This invention relates to improvements w for attachments for centrifugal driers or moisture extractors, especially those adapted for the drying of clothes in laundries or the like and has for one of its objects the provision of a removable chute to be attached to the top of such an extractor and to be used in the loading and unloading of same to prevent the loss of small articles which are being put into the extractor.

One of the principal objects of this invention is the provision of achute for a centrifugal extractor which shall be adapted to allow of the positioning of a container or tank for wet clothes adjacent the extractor and so guard the transfer of clothes from the container to the extractor that there will be no possibility of any small articles being dropped from the batch being transferred, into the space between the container and the extractor.

Another object of this invention is the provision of such a chute for centrifugal driers or extractors which can be readily attached to the extractor and as readily detached therefrom and which moreover can be positioned thereon at any convenient spot thereby allowing of the loading and the unloading of the same from any preferred angle or position. p

A further important object of this invention is the provision of a removable chute for loading and unloading centrifugal extractors which is adapted to catch any excess water or cleaning liquid from the clothes as they are being transferred and cause the water to drop back into the wet clothes container and thereby eliminate its dripplng into the space between the extractor and the clothes container which ordinarily results in a messy and sloppy condition of the floor around the extractor.

Another and further important object of this invention is the provision of such a chute for a centrifugal extractor which shall adapt the extractor to be used with a container for wet clothes whereby any container of any size or shape may be used ef iciently and which need not be positioned so close to the extractor as wouldordinarily be necessary in order to prevent the dripping of water into the space between the extractor and the container and alsothe frequent dropping of small articles of clothing into such spaces and onto the floor.

Other and further important objects of the invention will be apparent from the dis-` closures in the accompanying drawings and following specification.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings.

Figure 1 is a side elevation of a centrifugal extractor showing the improved chute of this invention applied thereto. l

Figure 2 is a top plan view of an extractor with the chute applied, the dotted lines showing some of the different positions into which the, chute may be placed.

Figure 3 is a detail sectional View taken on the line 3-3 of Figure 2.

As shown on the drawings:

The reference numeral 10 indicates an extractor or drier of the centrifugal type having a motor 12 positioned thereon for drivinv the rotatable container 14 therein and this extractor 10 is provided with the ordinary top or lid 16 having a handle or ring 18 thereon for proper manipulation thereo A water ring 2O is positioned around the top of the extractor 1() and is held in lace thereon by means of bolts or rivets 22. is water ring 20 is of almost the same type as is ordinarily supplied with these extractors', their usual purpose being to .form a hin plate and contact cover member for the lid l0@ 16, its inner ed es being beveled as shown in Figure 3.. owever, the water ring 2O of this invention is made slightly wider than the ordinary ring and is provided with an overhanging edge or lip 24 having a groove orl dot extending around the under side thereof. y

Adapted to fit under this projecting lip and into the groove 24, is the curved inner end of a chute or loading tray 26. The inner portion of this chute is so curved that it will correspond nicely with the groove in the under side of the water ring2() and .as this water ring extends substantially completely around thc top of the centrifugal extractor it is evident that the chute 26 may be positioned to extend in any desirable angle outwardly from the extractor, as shown in Figure 2. The chute 26 is provided with upstanding sides or edges 28 which are adapted to act as guards to prevent the running of water or liquid over the side edges thereof.

The operation is as follows:

In laundries lthe ordinary process of loading a centrifugal extractor of this type is to bring into position adjacent thereto a container having the wet washed clothes therein. 'llhe clothes are then transferred into the extractor by hand and it is found in practice that excess water is liable to drip from them and this excess water falls into the space between the extractor and the container, thecontainer being ordinarily of lrectangular form and having straight sides which therefore do not correspond very closely to the circular sides of the extractor thereby always leaving a space between the extractor and the container holding the wet clothes. rl`his results in the accumulation of a good deal of water on the floor around the base of the extractor resulting in a very sloppy and messy condition of the plant. Moreover, it oftens occurs that handkerchiefs and other small articles of clothing become detached from the batch of clothes which are being transferred from the container into the extractor and fall upon the Hoor, which being dirty and wet soils the article thus dropped which must necessarily be washed over again thereby resulting in a good deal of delay and ext-ra expense, es-` pecially when a single batch of clothes is being handled as a unit throughout the washing process.

llt will be seen that this removable chute g will act to prevent such dripping of water .while transferring the batch from the container to the extractor. rllhis is equally true when the clothes are removed from 131.19 @if Mieder tractor after having been dried, the liability to drop, being much greater as 4the moisture has almost all been removed therefrom leaving them in such a condition that small articles become more readily detached from the main mass.

The fact that this chute is detachable and movable, results in an appliance which is very convenient as it may be readily shifted from one position to another on the extractor thereby allowing of its loading and unloading from any desired position of the wet clothes container. No bolts or attaching devices of any sort are necessary. Moreover, it can be readily applied to any form of extractor now on the market, the only change necessary being that the Water ring which is ordinarily used in connection with these extractors be substituted by one which is slightly wider and provided with an overhanging lip and under cut groove as shown in Vthese drawings.

lf am aware that many changes may be made and various details of construction varied through a wide range without departing from the principles of this invention, and l therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
