JAMES H. JONES, F CLEVELAND, QHIO.

WASHING MACHINE.

Application filed Apri12, 1924, Serial No. 703,708. Rehewed December 1, 1928.

The objects of the invention are to provide a simple, eflicient and practical method of construction for the cylinder of a washing machine in which a metal construction is preferably employed. This cylinder is enclosed in an outer casing and its cover is preferably composed of woven wire material in order to permit the cleansing solvent to obtain freer access to the fabrics enclosed therein, and to enable it to act more effectually upon the same.

The invention comprises, the fabric washing cylinder and trunnion bearing extremi ties or heads therefor, and means for securing the edges of the cylinder wall to the circumferential edges of said heads without the use of rivets in the construction, since rivets often become loose and the fabrics may catch upon them and become torn and ruined thereby.

To overcome this difliculty the cylinder is composed of a perforated wall and disc shaped heads, the circumferential edges of which are grooved to provide seats or interlocking means for the edges of the cylinder wall, and a frame is provided by connecting the trunnion discs together by means of longitudinal spaced bars, which not only serve as connecting or binding means for the discs, but are provided with retaining means for the perforated material of which the cylinder wall is composed, and also serve as a bracing and strengthening means for the cylinder and serve as raising and distributing means for the fabrics enclosed in the cylinder. Also disc shaped partitions separate the cylinder into compartments and are secured tothe*covering material.

l he retaining means for the perforated material of the wall maycomprise longitudinal grooves in the longitudinal outer edges of said bars and circumferential grooves in the edges of the said trunnion discs, and partitions, .which are formed to receive molten metal in which the edges of the perforated materialor attaching i devices are locked, thus providing a solid integrally constructed device with no loose or projecting parts that can tear the cloths.

The outer edges of the perforated cover material are turned inwardly and are embedded in the molten'metal in the circumferentialedges 'of the trunnion discs, and

ing down its edges and embedding them in molten metal poured into the grooves there- 1n.

Also sliding doors are provided for door openings which are formed between the partitions and are so constructed that they will have no projecting parts upon which the fabrics may catch, and no openings in which the fabrics may catch or through which they may work: out of the cylinder, will occur at their edges. i

This feature is essential, particularly in the use of large machines where theweight of the fabrics in falling impart a considerable amount of pressure thereto.

Also a locking device for the doors is provided which is designed not only to lock the doors securely when the machine is in operation but is also constructed and arranged to lock the cylinder to the outer casing of the machine when the doors are open, and thus to prevent movement of the cylinder in the outer casing.

This feature is of great importance since with its use it will be impossible for any one to start the machine, when the door is open.

In operation, When the door lock is withdrawn it will automatically engage in a recess in the outer wall of the machine and the door cannot be opened until the bolt is so engaged. I

The invention further includes the combination and arrangement of parts and construction of details hereinafter described and illustrated in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings Fig. 1 is a perspective of the washing machine. I Fig. 2 is a circumferential section showing the door in its frame. Fig. 3 is a plan thereof and Fig. 4 a transverse section thereof. Fig. 5 is a transverse section of the entire cylinder on a reduced scale. Fig. 6 is a longitudinal section of one end thereof. Fig.

dering the door opening. Fig. 9 is a plan of a portion thereof. Fig. 10 is a longitudinal section of one end of the cylinder and one door.

In these views A, is the stationary enclosure or casing in which the cylinder B,

is rotatably mounted. The complete cylinder comprises a frame composed of the trunnion discs D, D, mounted on trunnions D, D, and spaced longitudinal bars H, provided with spaced perforations H, II,

rigidly connecting the said discs, and spaced partitions I, I, connecting the bars at intervals, thus separating the interior of the cylinder into compartments. This frame is preferably covered by means of sheets of perforated material E, openings being left at J, J, for the movements of the doors as shown in Figs. 1,2, 8, and 5.

All the ribs are longitudinally grooved at K, K, and the circumferential edges of the partitions are also grooved at L, L, and the edges of the trunnion discs are grooved at M.

To rigidly attach the circumferential edges of the perforated material to the trunnion discs, they are turned inwardly and inserted in the grooves M and sealed therein by molten metal poured therein at M. To rigidly lock the material upon the longitudinal ribs, these ribs are similarly grooved at K, K, and the edges of the material are turned downwardtherein and re- 7 tained in place by means of molten metal P,

poured therein.

If desired, further security may be provided by means of T-shaped bars Q, Q, embedded in the molten metal and turned over edges R, of the grooves as shown in Figs. 7

and 8. In Fig. 8 a longitudinal rib that is marginal to the front edge of one of the door openings is shown. This rib is rovided with an integral flange T into w ich t the edges of the door T, may enter.

Preferably. the edge of the flange is grooved at T to engage the edge of the door T, to preventthe contents of the cylinder from coming out of the opening. Also the circumferential edges of the partitions are grooved at L, L, and the perforatedmaterial passing thereover'is locked thereto by means of molten metal at X, X, (Fig. 6) in the grooves. Locking means such as staplesY, Y, which are engaged in sections extending from one longitudinal rib to another and having its ends secured in the emanner described in the longitudinal grooves, as shown in Figs. 7 and 8.

The doors are slidingly movable in the door openings and their rear edges when the doors 'T, T, are closed, are interlocked as shown in F igs.'2 and 3 with the turned over edges T, T, of the flange T Tfiupon the edge of the adjacent covering-material.

This'construction prevents the contents of casing A, and prevents the cylinder from revolving until the door is securely closed at which time the bolt is drawn from the outer casing and the lug T thereon engages the plate T in the door and preventsthe door from opening. In this manner the bolt has the dual purpose of locking the door and also alternately therewith locking the cylinder from moving so that the cylinder cannot move or the machine start until the bolt has been withdrawn from the casing and the door closed.

In Fig. 10 the doors T are shown to be provided with inwardly turned circumferential edges, forming grooves thereinand complementary engaging grooved edges T T, are attached, preferably b welding, to the edges of the grooves in tie trunnion disc, and partitions. These grooved edges form guides upon which the doors slide.
