Specification of Letters Patent.

Serial No. 503,612.

To all whom it may concern:

Be it known that I, J osnrrr SZAVA, a subject of the King of Hungary, residing at Mo- Keesport, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to washing machines, and the invention has for its primary object to provide in a manner as hereinafter set forth a sanitary machine that can be used for household and laundry purposes, and which is particularly adapted for cleaning, sterilizing and purifying fabrics.

WVith the above and other objects in View, which will more readily appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be hereinafter described and then claimed.

Referring to the drawings: Figure 1 is a side elevation of the detached lid of the washing machine, Fig. 2 is a side elevation of the machine with the lid detached, Fig. 3 is an end view of the machine with the lid attached thereto, Fig. 4 is a longitudinal sectional view of the machine with the lid detached, Fig. 5 is an end View of the revoluble cylinder of the machine, and Fig. 6 is a plan of the same.

The machine comprises an oblong receptacle having a base plate or bottom 1, inclined end walls 2 and inclined side walls 3. The base plate 1 is provided with depending cylindrical cups 4: adapted to fit in the stove lid openings of a stove, whereby the contents of theoblong receptacle can be heated to a boiling point. The sides of the base plate 1 resting upon a stove or similar heating medium, the receptacle is supported by angularly disposed legs 5, secured to the inclined side walls 3 of the receptacle. The upper edges of the inclined walls of the receptacle are provided with a vertical flange 6, and adapted to fit over said flange is a lid or cover 7, corresponding in cross sectional area to the receptacle of the machine. This lid or cover is provided with a handle 8 and the longitudinal sides thereof are provided with supporting rods 9 for hookshaped fasteners 10. These fasteners are adapted to engage hook-shaped brackets 11 carried by the longitudinal sides of the receptacle, said fasteners being slidable upon the rods 9, whereby they can be easily moved into engagement with the brackets 11 to retain the lid or cover upon the receptacle.

The inner sides of theinclined end wall 2 are provided with vertical bearings 12 for trunnions 13 and 14 which project from the heads of a hollow cylinder 15, the latter con stituting a vessel for the reception of the articles to be cleaned or sterilized. The cylinder 15 is provided throughout with longitudinally-extending rows of perforations, each of the rows of perforations being indicated by the reference character 16 and the said cylinder 15 is furthermore provided with a rectangular opening 20 in order that the articles which are to be cleaned or sterilized can be placed into the cylinder. At each side of the opening 20 a longitudinallyextending guide 22 is arranged. The guides 22 not only constitute means for guiding the lid 21 which is used to close the opening 20, but also to maintain said lid in position. The lid 21 is formed with a longitudinallyextending row of openings which form a continuation of a row 16 of the cylinder 15. Each row of perforations 16 is disposed between a pair of corrugated ribs 17, said ribs 17 extend longitudinally and from end to end of the cylinder 15 and are secured to the inner face of said cylinder 15 and constitute agitators for the contentsv of the cylinder. Arranged within the cylinder 15 and extending longitudinally with respect thereto are conducting pipes 18 perforated as at 19, the conducting pipes 18 are so disposed that each will be arranged between a pair of rods 17. The pipes 18 are secured in the heads of the cylinder 15 and each end of each pipe is open and said pipes communicate with the interior of the receptacle 1 whereby the contents of the receptacle can pass into said pipes and then discharge into the interior of the cylinder 15.

The trunnion 13 is provided with a collar 23 to prevent the cylinder 15 from shifting longitudinally in the bearings 12, and to rotate said cylinder in the receptacle of the washing machine, the trunnion is provided with a rectangular end or shank 2a to receive a hand wheel 25 having a crank 26, said hand wheel being retained in engagement with the trunnion 13 by a nut 27 screwed upon the reduced threaded end 28 of the trunnion.

The clothes to be washed or sterilized are placed in the cylinder 15 and the opening 20 of said cylinder closed by the lid 21. lVith the receptacle of the washing machine full of water and set upon a stove or similar heating medium, the machine is now in position to be operated to cleanse and sterilize the clothes within the cylinder 15. Since a portion of the cylinder 15 is immersed in the receptacle, the water within the receptacle ill enter the cylinder and as the cylinder is revolved through the medium of the hand wheel 25, the clothes within said cylinder will contact with the corrugations or ribs 17 and will be shifted about within the cylinder, whereby the hot water and steam. contained within the receptacle of the washing machine will be thoroughly disseminated in the clothes, and loosen and remove such matter or impurities that may adhere to the clothes.

With those parts of the washing machine made of non-corrosive material, it is im. possible for the clothes or fabrics contained within the cylinder 15 to become injured or marked by rust, and in view of the fact that the lid or cover 7 is clamped upon the washing machine, steam accumulating in said cover can pass through the perforations of the cylinder 15 and sterilize that portion of the contents of the cylinder 15 not immersed in the boiling water of the receptacle.

lVhile I have herein shown a hand wheel operating the machine by manual power, it is obvious that the machine when constructed upon a large scale can be operated by a motor or similar source of mechanical power.

While in the drawings there is illustrated the preferred embodiment of the invention, it is to be understood that the structural elements thereof can be varied or changed without departing from the spirit and scope of the invention.

Having now described my invention what I claim as new, is

1. A washing machine comprising a receptacle, a rotatable cylinder mounted therein and of the same diameter throughout, said cylinder closed at each end and having its body provided with longitudinally extending rows of perforations, longitudinally extending perforated pipes arranged within said cylinder, supported in the ends of the cylinder and opening at each end into said receptacle during the rotation of the cylinder, means whereby access can be had to said cylinder, longitudinally extending corrugated ribs secured to the inner face of said cylinder and extending from one end to the other thereof, said pipes alternately disposed with respect to said rows of openings and each of said rows of openings arranged between a pair of ribs and each of said perforated pipes arranged between a pair of ribs.

2. A washing machine comprising a receptacle, a rotatable cylinder mounted therein and of the same diameter throughout, said cylinder closed at each end and having its body provided with longitudinally openings and each of said rows of openings arranged between a pair of ribs and each of said perforated pipes arranged between a pair of ribs, supports within said receptacle, trunnions carried by the cylinder and journaled in said supports, and means arranged exteriorly of the receptacle and connected in one of said trunnions for rotating the cylinder.

3. A washing machine comprising a receptacle, a rotatable cylinder mounted therein and of the same diameter throughout, said cylinder closed at each end and having its body provided with longitudinally extending rows of perforations, longitudinally extending perforated pipes arranged within said cylinder, supported in the ends of the cylinder and opening at each end into said receptacle during the rotation of the cylinder, longitudinally extending corrugated ribs secured to the inner face of said cylinder and extending from one end to the other thereof, said pipes alternately disposed with respect to said rows of openings and each of said rows of openings arranged between a pair of ribs and each of said perforated pipes arranged between a pair of ribs, supports within said receptacle, trunnions carried by the cylinder and journaled in said supports, means arranged exteriorly of the receptacle and connected in one of said trunnions for rotating the cylinder, and a removable cover mounted upon said receptacle for inclosing said cylinder and supports.

In testimony whereof I aflixmy signature in the presence of two witnesses.
