WASHING MACHINE.

Application filed August 31, 1920. Serial 510. 407,289.

To all whom it may concern:

Be it known that I. AnoLr K. HANSON, a citizen of the United States, residing atChicago, in the county of (look and State of Illinois, have invented a new and useful Improvementin Vashing Machines, of which the following is a specification.

This invention relates particularly to washing-machines which are adapted for use in apartments, or where the conveniences of an ordinary laundry cannot be had,

The primary object is to provide a washing-machine which can be mounted in a bath-tub and conveniently operated therein.

A further object is to provide a machine of this character which may be compactly stored, when not in use.

The invention is illustrated, in its preferred embodiment, in the accompanying drawings, in which- Fig. 1 represents a plan view of the improved machine mounted in a bath-tub; Fig. 2, an end view of the washing-machine. the actuating mechanism being shown in section; Fig. 3, a vertical sectional view of the washing-machine, taken as indicated at line 3 of 'Fig. 2; Fig. 4, a vertical sectional view, taken as indicated at line 40f Fig. 3; and Fig. 5, a broken sectional view showing a detail of the perforate clothes-holder employed.

In the illustration, A represents a bathtub; and B the improved washing-machine combined therewith. V

The washing-machine comprises a casing B e uipped with adjustable supporting arms a perforate rotary cylinder B? mounted in the casing; and actuating mechanism B for the cylinder B The casing B may be .of any suitable form. It is shown as provided with a removable top 1. The arms B project laterally from the upper portion of the casing B. The casing is provided with end flanges 2 between which and studs 3 the supporting arms B at one side of the casing are slid ably adjustable. The slidably adjustable arms B are provided with longitudinal slots 4 through which extend threaded studs 5 which project from the ends of the casing and are equipped with thumb-nuts 5'. By

this means, the arms B may be adjusted, so that the hooked extremities 7 thereof may engage the upper edges of the lateral walls of the bath-tub. Two of the arms B are pivotally secured by similar studs and nuts nipple 16 fitted with a stop-cock 16.

' 5 and 5. When the washing machine is cylinder is equipped at one end with a trunnion 9 which is received in an interior bearirig 10 which is open at its upper side to adm1t the trunnion. At its other end, the cylinder isequipped with an angular-stud 11 which fits into a, socket 12 provided at the inner end of a trunnion 12, which extends through a bearing 13 formed integrally with a gear-casing 13 which is supported by brackets 13 secured to the end of the casing. The trunnion 12 has secured to its outer end a worm-wheel 14.- which is housed in the gear-casing 13 and with which meshes a worm 14: which extends parallel with the end of the main casing. The worm 14 is provided with a socket-end 14 which receives the angular end of the shaft 15 of an electric motor 15 which is suitably .supported on the end of the main casing B.

At one end of the casing B is provided a.

nipple is detachably connected with the faucet of the bath-tub by means of a hose 17. The casing B is further provided with a drain-passage 18, which is suitably stoppered when the machine is in use. machine is provided somewhat above the bottom of the casing with a discharge-spout 19 controlled by a stop-cock 19. The perforations 8 in the rotary cylinder B preferably are formed in the manner illustratedin Fig. 5, that is, the metal wall of the cylinder is struck inwardly, as indi- *the cylinder as the cylinder rotates The This Also, the

cated at 20, and is perforated; and the metal surrounding the perforation is curled outwardly, or beaded, as indicated at 20 The beaded portion is received in the recess or depression 20 which is formed by striking the metal inwardly. In this manner, the bead is flush with the outer surface of the cylinder .and only smooth metal is presented at the inner-surface of the cylinder. If desired, the cylinder may be equipped with the usual internal radial projections 21 which serve to engagethe clothes.

the cylinder is rotated by means of the electric motor until the clothes have been washed the required amount. The suds may then be drained from the casing or tub of the washing-machine into the bath-tub through the outlet 18. This outlet may then be closed and rinsing water may be allowed to run throu h the hose 17 into the casing B, the over ow 19 being open at this time, if desired. The cylinder maybe operated until the necessary rinsing has been effected, after" which the water may be drained from the casin B through the port 1 8.

The cy inder B is shown provided with a closure 22 which is hinged at 22 and fastened in the closed position by means of a knob 22". The closure may be applied in any desired manner, however. In the illustration given, the casing B is shown provided at its ends with handles 23; and the top 1 of the casing is shown provided with a handle 24.

It is to be noted that the washing-machine body is suspended in the bath-tub in such manner that practically the whole Weight of the washing-machine is below the level of the arms B Thus, the Washing-machine is very stably and staunchly supported in a very simple manner. Moreover, the source so of water-supply for the bath-tub is likewise available for use in small apartments, in

rooms for light housekeeping, etc., where usual laundry facilities are impossible or are not readily available. As may be readily surmised, there is a large field of usefulness for the improved machine, and hitherto there has been no machine adapted to the field.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claim should be construed as broadly as permissible in view of the prior art.

What I regard as new, and desire to secure by Letters Patent, is-

In means of the character set forth, the combination of a casing, two pairs of foldably mounted arm's connected with-the top of said casing and adapted to support the casing in a bathtub, one of said pairs being laterally adjustable, a rotary member mounted in the casing, and actuating mechanism for said member mounted on one end of said casin g ADOLF K.
