WASHING-MACHINE Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed August 12, 1908. Serial No. 448,210.

To all whom it may concern:

Be it known that I, ALBERT A. DAY, citizen of the United States, residing at borough of Brooklyn, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Washing- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in the novel features hereinafter described, reference being had to the accompanying drawings which illustrate one form in which I have contemplated embodying the invention and a slight modifica tion thereof and said invention is fully disclosed in the following description and claims.

Washing machines, such as are used in large steam laundries, are ordinarily provided with mechanism for reversing automatically the direction of rotation of the revoluble cylinder or inner casing after a few revolutions in either direction in order to prevent the balling of the clothes under treatment; and the sudden arresting of the cylinder and the sudden starting of it in the opposite direction, produces a considerable stram upon the mechanism, and further the construction of such mechanism as will render this action automatic, adds to the expense of the machine and the difliculty of keeping it in working order.

One of the objects of my invention is, therefore, to provide a washing machine in which the rotatable cylinder is rotated at all times in the same direction; and in order to provide for the proper agitation of the clothes and the application thereto of the water and cleansing materials, the interior of said rotating cylinder is provided, through the central portion, with a plurality of interiorly projecting blades or shelves; which while extending in a general direction around the interior are arranged in a zigzag manner, so that the clothing, as it is carried up on the rising side of the cylinder, will fall from one zig zag portion to another, and so on always toward the bottom of the cylinder. The end portions of the cylinder are provided internally with buckets so arranged as to carry up quantities of the water or liquid cleansing material, and said buckets have their bottom portions inclined toward the axis of the cylinder, so as to discharge the liquid with considerable force and in considerable quantity my present invention.

upon the clothes as they descend from one of the zigzag blades or shelves to another, thereby facilitating the elimination of dirt, etc.

In the accompanying drawings, Figure 1 represents a vertical sectional view taken longitudinally of a washing machine embodying Fig. 2 represents a vertical transverse section of the same on line 22 of Fig. 1. Fig. 3 represents a vertical transverse section of the machine on line 33 of Fig. 1, looking in the direction of the arrow. Fig. 1 is a vertical longitudinal sec tion of a slightly modified form of the machine, and Fig. 5 is a sectional detail of part of the construction shown in Fig. 4.

Referring to the drawings, 1 represents the exterior casing of the machine which is preferably cylindrical, although it may be made rectangular or of other polygonal form in cross section. This casing is supported upon suitable legs as indicated at 2, and is provided with a. suitable door, 3, by means of which access may be had to the interior. The casing 1 is also provided with both a discharge pipe 4 and an inlet pipe 4* having therein suitable cut off valves or cocks 5, 5 for drawing off and admitting the liquid contents when desired. An overflow pipe 49 is also provided as shown.

Within the casing 1 is the rotating cylinder 6, supported therein so as to be capable of rotation and here shown as provided at each end with a plate 7 having a trunnion 8 engaging a bearing 9 in the end wall of the outer casing 1. One of the trunnions 8 is extended beyond the bearing and provided with fast and loose pulleys 10, 11, as shown, or other suitable means for applying power to eifect the rotation of the cylinder 6.

The cylinder 6, in the form of my invention shown in Figs. 1, 2 and 3, has its centra portion provided interiorly with a series of inwardly projecting blades 12, each of which extends entirely around the interior of the cylinder, but in zigzag manner, thus providing a plurality of angularly disposed and opposed portions 13, 14 and as shown in Fig. 1. The angular portions 13 of all the blades are arranged parallel to each other and the angular portions 1 1 are arranged in a similar manner, although this is not essential. The end portions of the cylinder at each end are provided with a plurality of buckets, 15, extending from the head or end of the cylinder inwardly and having their bottom portions,

16, inclined from the ends of the cylinder 6, toward the longitudinal axis of the cylinder, so as to discharge their contents in a direction toward the central portion of the cylinder. The inner ends of these buckets are preferably entirely open, as shown in 1 and 3, so as to allow the water to be discharged therefrom with considerable force and in large volume; but they may be par tially closed. The cylindrical wall of the cylinder 6 throughout the central portion which is provided with the zigzag portions of the blades, is also provided with perforations 17, to permit of the free access of the water or cleansing liquid from the outer receptacle 1 into the interior of the cylinder 6. The cylinder 6 is also provided with. a suit able door 18 which can be opened when brought into alinement with the exterior door 3, to give access to the interior and the doors 18 and 3 are provided with any suitable securing means as desired.

In the operation of the machine, the receptacle 1 and cylinder 6 are filled to a desired level with water or other cleansing liquid, in the usual manner, the liquid level being prelerably below the plane of the axis of rotation of the cylinder 6. The clothes or other articles to be cleansed are charged into the cylinder 6 through the doors 3 and 18, which are then closed and secured in any desired way, and the cylinder 6 is rotated continuously in one direction. As the cylinder 6 rotates the angular blades 13, 14, on the rising side will tend'to carry portions of the articles upward and these articles will slide by gravity down said inclines from one to another, being arrested continually and having their direction of descent altered as they slide and 1111- pact from one zigzag portion to another. Simultaneously the buckets 15 at each end of the drum which will fill with liquid while submerged therein, will rise with the rotation of the cylinder and as soon as they pass above the liquid level will begin to discharge their contents with considerable force and volume upon the articles, thus facilitating their zigzag descent along the blades 13 and 14. The impacting or bumping action. which the articles of clothing receive from the zigzag blades and the coincident sensing of the cleansing liquid upon them from the buckets 15, causes the dirt, etc, to be-rapidly removed, and greatly facilitates the cleansing of the articles.

In Fig. 4 I have shown a slight modification of my invention in which 1 represents the exterior casing and 6 the rotatable cylinder mounted therein, as before described. In this case the central portion of the cylinder is provided with two or more circular series of inwardly extending blades 13 and 14, the blades of one series alternating with and being oppositely inclined to the blades of adjacent series. The end portions of the cylinder are provided with buckets 15 simi lar to the buckets 15, previously described, having inclined bottom portions inclining toward the axis of the cylinder, but having at their discharge ends a retaining wall 19 provided with one or more discharge apertures 20 of less aggregate area than the end of the bucket, so as to retain the liquid longer as the buckets rise and discharge it therefrom more slowly than where the entire inner end of each bucket is open.

The operation of the apparatus shown in 7 Figs. 1 and 5 is practically the same as that previously described. In all cases the inner wall of the bucket which extends into the interior of the cylinder has its inner end or corner beveled and inclined as indicated at 21, Fig. 1, so as to permit any articles of clothing which might otherwise catch thereon, to slide off into the center of the cylinder.

What I claim and desire to secure by Letters Patent is 1. A washing machine provided with a retating cylinder having portions between its ends provided with inwardly projecting blades disposed angularly with respect to each other and its end portions provided with buckets adapted to discharge in a direction towards the said blades, substantially as described.

2. A washing machine having a rotatable cylinder provided interiorly with a plurality of blades projecting inwardly h'om the cylinder wall and disposed angularly with respect to each other and an annular series of buckets at each end of the cylinder having bottom portions inclined toward the axis of rotation of the cylinder, said buckets having'discharge apertures at their inner ends, substantailly as described.

3. A washing machine having a rotatable cylinder provided interiorly between its end portions with inwardly projecting blades ex tending in zigzag form around the interior, the zigzag portions of said blades being substantially parallel to corresponding portions of adjacent blades, said cylinder having an annular series of buckets at each end having their bottom portions inclined toward the axis of rotation of the cylinder and being provided with discharge apertures at their inner ends, substantially as described.

In testimony whereof I arfix my signature, in the presence of two witnesses.

ALBERT A. DAY.
