SPECIFICATION forming part of Letters Patent No. 440,204, dated N ovembel 11, 1890.

Application led April 7, 1890. Seria1No. 346,853. (No model.)

To all whom it 77mg/ concern:

Be it known that- I, GEORGE L. SHOREY, a citizen of the United States, residing at Lynn, in the county-of Essex and Commonwealth of Massachusettshave invented certain new and useful Improvements in Washing-lvlaellines, of which the following is a full specification.

My invention relates to washing-machines of the class wherein an inner perforated cylinder containing the goods to be washed has a rotative movement within a stationary cylinder containing the water and suds; and it consists especially of improved locking devices applied to the inner cylinder, whereby when the floor of the said inner cylinder is open the inner cylinder is firmly looked to the outer, so that it is impossible to start the ma-v chine in this position. This fastening device, besides insuring the absolute safety of the operator, prevents all possibility of wrenching off the inside door by accidentally starting the machine while the door is open or before it is made fast, the construction being such that before the door can be opened at all the two cylinders must be locked together. Furthermore, the door is held iirmly fastened when shut in such a manner thatit cannot get loose while the machine is in operation.

Referring to the accompanying drawings, Figure l is a perspective view of a machine fitted with my improved devices, showing the door of the inner cylinder open. Fig. 2 is a sectional elevation of the same machine, showing the inner-cylinder door closed. Fig. 3 is an enlarged plan view of part of the inner-cylinder door and adjacent parts. 4 is an enlarged sectional View on line .r fr, Fig. 3, but with the door open.

The general form of machine to which my safety devices are applied is similar in construction to that shown and described in an application for Letters Patent of the United States, filed by me, for an improvement in washing-machines, the Serial nu mber of which application is 346,854.

The machine is preferably made of metal throughout.

A A are the legs or standards supporting the outer cylinder, being bolted or otherwise iirmly secured thereto. The outer cylinder,

which is preferably of cast-iron, is made as herein shown, in two similar sections, an npper and a lower. The upper section consists of the semi-cylindrical portion B and the semicircular ends D, and the lower section of the corresponding parts B D D', the two sections being bolted together'along suitable side and end flanges b d, as shown in Figs. l and 2, to from a water-tight receptacle.

The outer cylinder is provided with adoor 6o B2, furnished for convenience with knobs or handles b, and sliding along the top of the cylinder under guides B3 on each side thereof.

At the bottom of the outer cylinder is the water-pipe E, connecting with the interior, while an open-top water-gage G, also communicating with the interior through the holef,

is placed at theproper level upon the cylinder-head, showing the height of water in the cylinder and the condition of the suds with- 7o out opening the door B2.

The inner cylinder is suitably mounted on shafts F2 at each end, which are journaled in bearings in the ends of the outer cylinder. The material of the inner cylinder, which comes in direct contact with the goods in washing, is preferably brass, the walls of the cylinder being in the machine herewith shown composed of staves L, perforated with a large number of holes l, and bound by bands lover 8o the end pieces I of the cylinder and to the central partition C.

The inner cylinder is given a rolling motion around its axis back and forth within the outer stationary cylinder by means of suitable reversing mechanism supported by the bracket M on one end of the outer cylinder. Fixed on the outer end of one of the shafts F2 is the gear N,through which motion is given to the inner cylinder, rst in one direction 9o and then in the other. Any desired mechanism maybe employed to accomplish this; but I preferably use mechanism similar to that shown and-described in United States Letters Patent No. 246,916, granted to me September 13, 1881, for automatic reversing devices, to which reference is hereby made.

The door of the inner cylinder is made of staves L similar to thoseiforming the cylinder-walls, but shorter, being perforated with 10o der. The door, as here shown, is formed of two staves L and anadditional strip L2'along the front thereof, and is furnished with knobs or handles Z4 for convenience in opening and closing the saine. At each end of the door on the end pieces of the inner cylinder are bolted or otherwise secured blocks K', in which slide bolts k, bearing the locking-heads K. As here shown, two of these locking-bolts are arranged at each end of the door, one near the hinged side and one near the outer or fr ont side thereof. Each bolt lo is provided wlth a pin k2, sliding in a guiding-slot 7c inade in the block K Vhen the door in the inner cylinder is directly o'pposite the door 1n the outer, the bolts 7c are directly opposite recesses 7a3 (see Fig. 2) made either 4in the ends of the outer cylinder or in some piece or pieces connected therewith.

In the present machine the recesses k3 are made in a piece K3, secured to the ends of the outer cylinder and passing completely around the same. When the doors in the two cylinders are directly opposite each other, the bolts k may be pushed outward into the recesses 7c3, which thus locks the two cylinders together, making it impossible to start the machine. When all of the bolts are thus slipped back, the heads K thereof are clear of the door, which may then be opened, thebolt-heads K then being in the position occupied by the upper one. (Shown in Fig. 3.) The shape of the locking-heads K is such that when 'the door is closed, as in Figs. 2 and 3, and the bolts pushed inward, in the position occupied by the lower bolt in Fig. 3, the head bears upon the door, preventing it from being raised. Moreover, when all the bolts are pushed out into the recesses los, thus locking the two cylinders together, and the door raised, the shape ofthe locking-heads K is such that the bolt-head at each end nearest the hinged side of the door isprevented fromfbeing slid inward by bearing against the door itself, as shown in Fig. 4,'so that when the door is open it is absolutely impossible to start the machine, since, although the lower of the bolts k on either side may be slid in and out, the upper ones, or those nearest the hinged side of the door, are held back bythe door itself, in the manuer described. When once the door is closed and'all the bolts slid inward, thus locking it in its closed position, it will be equally iinpossible for the bolts to slip back while the machine is in motion, by reason of the fact that only when in one position-viz.,with the bolts la opposite the recesses 7c3-can the door be unlocked. In other words, locking the two cylinders together unlocks the door, and locking the door in a closed position releases the inner cylinder.

I claiml. A washing-machine having a stationary outer cylinder provided with a door and a perforated inner cylinder rotatively movable within said outer cylinder, the inner cylinder being provided with a hinged door andwith slidin g locking-bolts seated in blocks secured to said inner cylinder and engaging with recesses made in the ends of the outer cylinder or in pieces connected thereto, whereby locking the two cylinders together unlocks the door and locking the door releases the inner cylinder, substantially as described.

2. In awashing-n1achine,a stationary' outer cylinder providedwith a door, in combination with a perforated inner cylinder rotatively movable in said outer cylinder provided with `a hinged door and having locking devices engaging with the outer cylinder, larranged whereby locking the twov cylinders together unlocks the inner door, and. locking the inner door releases the inner cylinder, substantially as described.

3. In a washing-machine, a rotatively-movabley cylinder having a hinged door, in combination with bolts sliding in blocks secured to said cylinder, and having locking-heads y.arranged whereby when the door' is closed the bolts may be slid inward, but when it is open the said bolt-heads are arrested by the door itself, substantially as and for the purposes described.

In Witness whereof I have hereunto set my hand.

GEO. L. SHOREY.
