IMPROVEMENT IN WASHING-MACHINES.

The Schedule referred to these Letters Patent and making par; of -the same- Toall whom it may concern:

Be it known that I, CHARLES B. BRrsToL, of the city and county of New Haven, in the State of Connecticut, have nvented a new and useful- Improvement inWashing-lNIachines; and I do hereby declare that the following is a full, clear, and exact description of the construction, Cl1aracter,'ainl 4operation ot' the same, reference being had to the accompanying drawings, which make part of this specification, in which- Figure 1 is a perspective view of the whole apparatus, showing the two rollers, posts, bar, 85e.

Figure 2 is la section of the same, cut vertically through the centre in the longitudinal direction of the rollers. y

- My improvement consists in the use of two rollers, beaded or lluted transversely, so as to form transversely corrugated surfaces, so arranged that the most prominent portions or beads of one will work in the most depressed, portions or grooves of the other, so as to produce bot-h a pressing and a rubbingoperation, as the clothes are alternately drawn up from and lowered down into the water, on either side, hy revolving the crank, alternately, in the opposite directions, according to the length of thearticle to. be washed, while the journals of the rollers rest in slots, and the upper roller is pressed down by springs, so as to press the clothes suliiciently, and yet yield readily, to prevent damage to buttons, or any other enlargement or variation in thickness, and inthe use ofa bar, faced with a strip or plate Aof India rubber, with its upper edge -undnlated or serrated, to lit the surface of the lower roller, to prevent strings or Small strips of cloth from getting wound around it.

I make the frame of the working-apparatus of two posts, A and B, and a cross-bar, as indicated iu section at a and b, tig. 2, and I secure this bar to thef posts by pins, or any other suitable means, and on one of the vertical sides of this bar a b, I nail, or otherwise secure, a strip or plate of India rubber, as represented at C, figs. l and 2, with its upper edge unduf lated or serrated, as represented at c, tigs. l and 2, to suit thesurface of the lower roller, which I place so near to the roller D, as to prevent any string, strap, or narrow strip of cloth from passing round the roller D, so as to entangle or interrupt the work or operation of washing.

I make the posts A and B with a slot in each, as

represented at d and c, from the top to a point sutilciently low, or far enough down, to serve as bearings for the journals of the lower roller D, and I bore or make a round hole iu communication with each slot, to receive a suitable spiral spring, as represented at k and l, tig. 2, and on the tops of these posts I tit caps, as represented at f and g,and securethem by screws, as represented at h and t, figs. l and 2, so that the caps maybe swung round, to cover or uncover the slots, for the purpose otinserting or removing the journals and springs, whenever it is nccessaryiu using the machine.

I make the rollers D and E with transverse beads and grooves,`and so arrange them that the most prominent portions .or beads on one roller will work in the most depressed portions of the other, so that if the upper roller E is revolved, the frictionof the beads and grooves will cause the lower roller d to revolve in in the grooves d and e, where it comes nearly in contact with the serrated edge c, ot' the rubber 'plate C, on the bar a b, but so that it may be revolved freely.

I then drop the journals ofi the upper roller E into the same slots (l and c, and allow it to fall down till its transverse beads or prominent circles fall into the transverse grooves iu-the lower roller l).

Ithen drop in the circular pieces of leather, to support the lower ends ot' the springs lo and -l, as represented at nt and n., igll, drop in the springs k and l, press them down snliiciently, and turn the caps f and g over the slots d and e, when the Inachine will be ready for use.

To use this machine, I put a sutlicient quantity of water into the'tub F, and put in theclot-hes, applying soap, &c., at discretion, pass one end `or corner of anar-ticle to be washed between the roll- -ers yI) and E, and revolve the roller E, by means of the crank G, until the article has passed nearly through, and then turn the crank in the opposite direction, and so on, alternately, till the article is fully washed. l

The advantages of my improvement consist in,

4that it can be made at far less expense than any each other, will afford al1 of the advantages of both pressing and rubbing, with the least strain on the clothes or articles being Washed.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the two rollers D and E with the slotted posts A and B,`the springsk and l, and caps f and g, when constructed, arranged, and fitted for use, as herein described and set forth.

2. The combination of the lower roller D, with the har a b, while sustaining its India-rubber plate G, when they are constructed and arranged as herein described and set forth.
