ROTARY LAUNDRY MACHINE.

Application filed. March 3, 1927. Serial No. 172,383.

This invention relates to rotary cylindrical laundry machines and has for an object the provision, in such a machine, of adjustable partitions for dividing the cylinder into compartments of any desired relative sizes whereby a plurality of washings of any variety of sizes may be handled in said machine coincidently, while keeping the lots separated and maintaining the balance of the cy inder to prevent wabbling during revolution thereof.

Herein l have illustrated the invention in its preferred form as incorporated in a laun dry machine having a vertical cylinder with perforated sides through which perforations the water from the contained laundered ar-,

ticles is thrown out by centrifugal force when the cylinder is rotated on its center bearing, for drying the contained articles.

Other objects will appear from the following specification and claims and the accompanying drawing in which like reference characters indicate corresponding parts throughout and in'which Figure l is a view of a rotary cylindrical laundry machine with the invention installed therein, the lower portions being shown in elevation and the upper portion in section on line A-A in Figure 11.

Figure ll shows a section on line B-B hi re 1.

igure Hill is a detail view of one of the partitions.

The machine illustrated in the drawing is of common type, having a casing or tank 1 with a screen, removable top 1 supported by and commonly formed integral with standards 2 rising from base 3 and provided with a drain l. Within the casing or tank 1 is a cylinder 5 having perforations 6, a central opening 7 in the top, the cylinder being mounted upon the upper end of shaft 8 to revolve therewith, the shaft being revolubly mounted in a seat 9 and having a revoluble water tight mounting through the bottom of the casing as shown generally at 10 and carrying a pulley 11 for belt 12 connected with an suitable source of power, not shown. I

haft 8 is provided with a central bolt 13 projecting up through and above the bottom of cylinder 5 and threaded for reception of nut 14 for holding the cylinder tightly on shaft 8. A washer 15 may be provided. Thus far the description is of the common machine in which wet clothes placed in the cylinder are dried by having the water forced therefrom throughperforations 6 by centrifugal force'u on the rapid revolution of the cylinder by belt 12 revolving shaft 8.

In laundry work it is frequently necessary to handle small lots of clothes keeping each lot separated from other lots during the washing and drying. The machines are, and for general utility should be, large enough to accommodate within the cylinder at large lot of clothes. To use such a large machine for a sin le small lot is uneconomical but to place a p urality of small lots in the cylinder in-. volves danger of mixing-the lots, destroying their separate identity. It is, therefore, desirable to provide means whereby a plurality of small lots of clothes may be handledin and by the machine coincidently while keep ing the lots separated. llt is also necessary that the arrangement be such that the contents of thepylinder shall be always well balanced in order not to cause wabbling during rapid revolution and for economy and eficiency the arrangement should be adjustable according to the various sizes of the respective lots of clothes.

To meet these requirements I provide a plurality of partitions 16, carried by and up standing from plates 17, preferably of substantially triangular shape and having means as holes 18 for revolubly mounting the same on bolt 13. The plates 17 lie at and substantially parallel with the bottom of cylinder 5 and the partitions preferably stand substantially perpendicular thereto.

Preferably a collar 19 with a flange 20 is positioned on the bolt 13 under the nut. and washer 14 and 15 and the holes 18 are made large enough to fit over the-collar. The plates'17 and partitions 16 are mounted with suficient looseness to permit of their easy manual movement around the central mounting so that they may all be nested together in case of the use of the machine for a single large lot of clothes or be separated so as to form a plurality of compartments of the various desired sizes within the cylinder (as clearly illustrated at Figure II) for the accommodation, while preserving the separateness of, a plurality of small lots of clothes of various sizes.

The plates 17 are important. The clothes placed in a compartment along the bottom of which a plate extends, lie upon such plate and theweight of the clothes holds the plate 17, and thereby its artition 16, in position as placed. Genera y the clothes will lie partly upon the plate and partly upon the bottom of the cylinder which tends still more to hold the plate and its partition from dis-'- placement. Partitions carried by underlying plates may be notched as at 21 to accommodate overlying plates.

It will be apparent that with partitions constructed and mounted substantially as described, a cylinder may be used as a single compartment or may be divided into any desired number of compartments not exceeding the number of partitions and that compartments may be varied in size from one small enough for the smallest single piece of cloth to be handled, up to the full capacity of the-cylinder and that by adjustment of the sizes of compartments according to the sizes of lots of clothes to be handled, a balance of the cylinder may be easily maintained and wabbling thereby prevented. I Variation of detalls of construction, within' the spirit of the invention and scope of the claims will occur to those skilled in the art. I

I claim- 1. In a cylindrical centrifugal drier, artitions mounted within the cylinder an independently revoluble around its axis for dividing the cylinder into longitudinal com-- partments.

2. In a cylindncal centr fugal drier,

plates mounted within the cylinder for revolution around its axis in a plane near and substantially parallel to the bottom of the cylinder and partitions carried by the plates 1 revoluble around its axis for dividing the cylinder into longitudinal compartments, and plates connected with said partitions and adapted to lie adjacent to and in a plane substantially parallel with one of the walls of the cylinder.

5. 'In a cylindrical centrifugal drier, partitions mounted within the cylinder and independently revoluble' around its axis for dividing the cylinder into longitudinal compartments adjustable as to size.

In testimony whereof, I aifix my signature.
