STATES NiTE WILLIAM GEORGE GIBBINS, OF LEYTONSTONE, ENGLAND.

WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 718,754, dated January 20, 1903.

Application filed October 28,1901. Serial No. 80,314. (No model.)

To 60% whom it may concern:

Be it known that I, WILLIAM GEORGE GIB- BINS a subject of the King of Great Britain and Ireland, residing at Leytonstone, in the county of Essex, England, have invented 1mprovements in Washing-Machines, of which the following is a specification.

In the specification of former Letters Patent granted to me, No. 638,180, dated November 28, 1899, is described a washing-machine comprising an oscillating vessel having mounted within it a squeezer, between which and the sides of the vessel the goods are squeezed, and the arrangement illustrated in said specification is such that While the goods on one side of the squeezer are being squeezed those on the other become immersed in the cleansingliquid, the movement of which turns them over.

.The present invention has reference to washing-machines of this kind, and according thereto the squeezer is arranged to conform more or less closely to one side of the vessel and the goods are placed between it and the other side of the vessel, by which arrangement the goods are allowed greater freedom while being turned by the oscillation of the vessel and the consequent movement of the cleansing liquid.

In some cases it is desirable to squeeze the goods only once during two or other given greater number of complete oscillations of the Vessel. To provide for this, the squeezer is actuated by suitable means in such wise that it oscillates with the vessel during one oscillation or two or more consecutive oscillations thereof and is given a tendency to maintain an attitude approximately corresponding to the upright position of the vessel or to oscillate reversely to the vessel, so as to squeeze the goods during the next oscillation of the vessel, and so on.

Referring to the accompanying illustrative drawings, Figure 1 shows a power-machine according to the present invention in front elevation, and Figs. 2 and 3 are elevations of the ends thereof. Figs. 4 and 5 are cross-sections on the lines A A, Fig. 1, the machine being shown in a different attitude in each. Fig.

6 is a detail sectional view on the line 6 6 of Fig. 5.

1 is the oscillating vessel, which is provided with trunnions 2, resting in bearings 3 on the frame 4 of the machine.

The vessel 1 is formed with an opening 5, through which the goods and cleansing liquid are charged and discharged. The opening is closed by a lid 6, secured in place by catches or buttons 7.

The main shaft 8 extends lengthwise of the machine and carries at one end fast and loose pulleys 9 and 10 and at the other end a crank-arm 11, that is connected by a rod 12 to a toothed segment 13, pivoted at 14 to the frame 4 and gearing with another toothed segment 15, fixed to one of the trunnions 2.

The squeezer 16, which is fixed to a shaft 17, extending throughout the length of the Vessel 1 and through a suitable gland 18 in one end thereof,is in the form of a perforated brass plate 16, which conforms more or less closely to the one side wall of the vessel 1. The goods' are placed between the squeezer and the other side wall of the vessel 1. Both the side walls are curved as described in the specification of my before-mentioned Letters Patent, so that the liquid in rushing from one side of the vessel to the other will tend to turn over the goods While they are not being squeezed, so that different surfaces of the goods are presented to the partition and wall when next squeezed.

The brass squeezerplate 16 is fixed to curved arms 19, projecting from the shaft 17, and is faced with longitudinal rubbers or slats 20, that are secured in place at the required distance apart by a binding-strip 21 at each end, which strip is beveled or slopes outwardly, as shown in Fig. 6, toward the adjacent end of the vessel 1 in such wise as to tend to push the goods away from the end of the vessel. Opposite the squeezer the side wall of the vessel 1, which is lined with brass or copper 1*, is provided internally with rubbers or slats 22.

On the shaft 17 is an external arm 24, that is provided with a roller 25, which travels over the face of a curved bar 26, that forms a path which is concentric with the center of oscillation of the vessel 1 for a portion of its length and maintains the squeezer 16 close to the one side of the vessel. Beyond this concentric portion a curved bar 27 is pivoted at 28 to an angular projection on the bar 26, so that it can be moved into such an attitude that the roller 25 during the oscillation of the vessel will travel along the back or outer part of the bar 27, which then serves as a cam-path to force outwardly the roller 25, and thus swing the squeezer 16 toward the middle of the vessel 1, relatively speaking, so as to squeeze the goods. To prevent shock between the roller 25 and the concentric portion of the bar 26 during the return movement of the vessel, this bar is continued around and parallel with the back of the cam-path 27 when the latter is in its operative attitude, Fig. 5.

In some cases the cam-path 27 may be pivoted upon the continuation of the concentric part of the bar 26, which bar is pivoted at 29 to the machine-framing and is normally held in position by a spring or springs 30, but is capable of moving in opposition thereto. The free end of the bar 27 is provided with a stop or link piece 27, which serves to limit its movement relatively to the bar 26. This means enables the squeeze to be applied to the goods with the required pressure, but allows the squeezer 16 to yield if the pressure becomes excessive.

For the purpose of moving the bar 27 at the times required to cause the goods to be squeezed only once during two or other given greater number of oscillations of the vessel 1 any suitable means may be employed. In the arrangement illustrated the shaft 8 carries a pinion 32, that gears with a wheel 33, provided with a projecting pin or arm 34, adapted to push out of its path the one end of a bent lever 35, pivoted at 35 to a lug 35 The other end of the lever 35 extends beneath a pin 35 Fig. 3, projecting from the bar 27. The movement of the lever 35 by the pin 34 is thus adapted to raise the nose of the bar 27 to allow the roller 25 to pass beneath it; but the pin 34 clears the lever 35, and thus releases the bar'27 in time to allow it to again fall into its inoperative attitude as soon as the roller 25 clears the bar 27 during the backward oscillation of the vessel 1.

Other means than those described may be employed for causing the squeezer to oscillate with the vessel during one oscillation or two or more consecutive oscillations thereof and to maintain an attitude approximately corresponding to the upright position of the vessel or to oscillate reversely to the vessel during the next oscillation thereof, and so on.

37 is a dirty-liquid-discharge valve, which can be operated by a hand-lever 38. The vessel 1 can be charged with hot or cold water through the

pipes

39 and 40, respectively, which are connected to one of the trunnions 2, which is hollow and connected to the well 1 of the vessel 1 by external pipes 41 and 42. 43 is a steam-supply pipe, also connected to the hollow trunnion and is fitted with a pressure-gage 44.

The vessel 1 is fitted at 45 with a safetyvalve and at 46 with a cock to allow escape or admission of air as required.

Washing-machines according to this invention may be variously modified and some of my improvements may be employed without others.
