kWASHING.-

MACHINE.

SPECIFICATION forming part of Letters Patent No. 593,856, dated November 16, 1897. Application filed January 13, 1897. VSerial No. 619,087. (No model.)

ducing my'present invention is to improve upon the machines shown and described in said Letters Patent.

My present improvement relates mainly to the -formation of the working surface of the master-roller and to the matter of covering or inclosin g the outer ends of the smaller eX- treme rollers. e

The object of my present invention is to cause the master-roller to aetless harshly and p 2 2 in Fig. l.

scribed, and. more more softly upon the fabric of the clothes being washed and to keep the clothes more evenly distributed throughout the length of the rollers; and a further object of the invention is to provide cup-plates for receiving within cavities therein the outer ends of the smaller rollers to prevent the clothes from running between them and adjacent parts of the machine, and thus prevent the clothes while being run through the machine being caught and held by said rollers.

The invention is hereinafter fully departicularly pointed out in the claim. y

Referring to the drawings, Figure 1 is a side elevation of my improved washing-machine. Fig. 2 is a plan of the same, the tub being horizontally sectioned as on the dotted line Fig. 3 is an end elevation of the device seen as indicated by arrow 3 in Fig. 1, the lower bar being vertically sectioned on the dotted line at the point of the arrow. Fig. 4 is an elevation ofthe inner surface of a standard of the frame viewed as indicated by arrow 4 in Fig. l, the upper and lower horizontal bars being vertically sectioned as on the dotted line at the point of the arrow. Fig. 5 is an edge view of the cupplate for covering the ends of the rollers seen as indicated by arrow 5 in Fig. 4. Fig. 6 shows the manner of covering the ends of the rollers, the plate being vertically sectioned through the axis of the roller. Fig. 7 is an end View of the lmaster-roller, showing the distribution of the studs thereon.

Figs. 6 and 7 are drawn full size, Figs. 4 and 5 are drawn to a scale one-half size, and the remaining figures to a scale one-fourth size.

'Referring to the parts shown, A is the frame of the machine, it consisting of upper and lower bars a and ZJ and standards c c. This frame is adapted to rest within the tub B, reaching diametrically across the tub and held to place by fasteners CZ d, all substantially as shown and described in said Letters Patent No. 349,747. The frame is provided with a series of relatively small oor or bed rollers c, Figs.'1 and 6, preferably arranged in three parallel rows just above the bar b, as shown in Fig. 4'. These rollers turn on horizontal rods f,having their ends held in the standards of thevframe, said rollers being fully described and shown in the Letters Patent No. 200,220. A pair of horizontal rods, one of which is shown at g, Fig. l, reaches between the standards c c, being secured ine the latter, which rods hold a serie's of supports or yokes h for the shafts of the bed-rollers, all of which are fully shown and described in said Letters Ratent.

Above the bed-rollers and between the standards rests a master-roller C, Figs. l, 2,

and 7, to coact with said bed-rollers, held upon a shaft i, extending through vertical slots k,'Figs. 3 and 4, in the standards c c. The shaft 'i is substantially without rigid bearings, but is adapted to move upward or downward in the slots in the standards as the clothes passing through between the rollers are greater orless in bulk. The masterterroller is turned by a crank D in the usual manner, secured to the shaft c'.

' The mastenroller C in my present inventionis preferably a plain cylindrical piece of wood,

provided with a series of studs o, having large button-heads and pins p, Fig. 7, tobeA driven into the roller. These heads are preferably of rubber, and hemispherical in form, and the studs are placed in twelve (more or less) longitudinal rows along the convex surface of the roller. The studs arev separate and independent of each other, and are removable, so as to be replaced by new ones when the old ones are worn out. The yielding nature of the rubber heads causes the master-roller to act softly upon the fabric of the clothes being washed, and there is little or no tendency in its action to pull buttons O of the clothes. In using the wooden grooved or uted roller bu-ttons are liable to be caught in the grooves, and so be detached from the cloth.

The standards c c of the frame are provided with plates E, Figs. 1,4,5,and 6, resting against theirinnersurfaces. These plates are formed with shallow circular cups o for the vpurpose of receiving within them and covering the outer ends of the extreme bed-rollers, as clearly shown in Fig. 6. The cups, covering the'en ds of the rollers, eifectually prevent the clothes while passing through the machine from run-ning over the ends of these rollers and becoming caught between them and the standards. This is very important, as by means of these plates the clothes pass freely through between the rollers without being caught or otherwise held. The plates are also formed with parts or rests s, Figs. 3 and 5, to project into the slots 7.: 7.; at the bottoms thereof to form bearings for the shaft z' when at its lowest position.

These rests serve to hold the master-roller so the heads of the studs shall just clear or only touch the bed-rollers when there are no clothes in the machine. This prevents the heads ofthe studs becoming worn by rubbing against the bed-rollers on account of the turning of the master-roller when there is'no fabric between it and the bedfrollers to keep the parts separated. The bands Z Z act to continually pull the master-roller downward, and if no stops were provided to con trol it the studs would be brought irmly against the bed-rollers in the absence of anything to separate them, on account of which the studs l might become injured.

Vhat I claim as my invention is- A washing-machine having a slotted frame and a series of bed-rollers in the frame, and a master-roller over said bed-rollers to coact with the latter, and means for turning the master-roller, in combination. with plates having cups or cavities upon one surface at one end in which to receive and to cover the eX- treme ends of the bed-rollers, and a rest upon the opposite surface of the other end, said rest projecting into the slot of the frame and so related to the cavities that the surfaces of the respective rollers j ournaled therein cannot touch each other substantially as and for the purpose specified.

Inwitness whereof I have hereunto set my hand, this 7th day of January, 1807, in the presence of two subscribing witnesses.

JOHN V. RICKER.
