Description

ALVIN B. CLARK AND GHARLESDAVIS, oFnIoHMoND, INDIANA.Y
.Letters Patent No. 74,502, dated February 18, 1S68.
IMPROVED WASHING-MAGHINE.

To ALI. WHoM IT MAY ooNeEnN:
Be Ait known that we', ALVIN B. CLARK and CHARLES DAVIS, of the city of Richmond, and Sta-te of Indiana, have invented a new and useful Improvement-in Washing-Machines; and we do hereby declare that theffollowing is a. full, clearfnnd exact description'of the same, reference being had to the accompanying drawings,A making a. part of this specification, in Which-e- Figure 1 is aperspectit'e View, y
Figure 2 isa. horizontal section, and
Figure 3 a. longitudinal section.
Thesame letters, in the diiferent figures, relate to corresponding partsif the invention.
Our invention relates to e. washing-machine, withvwhich the operation of washing is performed by machinery, in a. manner closely imitating the same operation as performed by hand. The rubbing, as when 'done by hand, may be applied to any particular portion of the clothing requiring extra. labor. i
Tp enable others skilled inthe art to make and use our invention, we will proceed to describe its construction and operation. j
A represents a rectangular box or tank, which, for convenience, is snpported'on legs. B and B represent beams, attached rigidly togsaid tank, for the purpose of supporting the extending-mechanism. An ordinair/yr wash-board, or other corrugated device, is secured, temporarily or permanently, on the stationary platform y, which latter is fixed .to the sides vof the tank.V a represents a. roller, having itsjournal-benrings, S and S, in the hangers L and Zz. d and d are reciprocating rods, 4having their bearings at t and t and u and u. '.A transverse rdd or section of the same rods, connects them at end ce. To the front ends of said rods.are attached thehangers ZI and 6'.' D represents a crank-shaft, linked with pitman n to rod x. e and e'are` ratchets attached to the ends of roller a. I and I represent pawls tha't engage with said ratchets, the `pawls being hinged to rod x. g rep-V resents stay-rods connecting pawls I and I. V and Y are spiral springs acting on the journals of roller a, by
which the pressure of the latter is modied.
The power is applied by means of crank r, thus imparting a reciprocating motion to rods d and d, by which roller a 'is made to traverse wash-board C. In its forward motion, roller a is prevented from rotating by the action of ratchets e and e', but is'allow'ed to rotate at the return stroke. Thus the clothing, after being placed by the operator on the wash-board, and Within reach of roller a, is gradually Acarried ,through by the friction 'of said roller, as it slides over the surface of the board at each alternate stroke, and thus rubbing 'the clothing in a manner very similar to that of hand-washing. By a slight pressure of the hand on the garment, it may he stopped from feeding, and thus the rubbing is applied as long as necessary to any particular spot requiring extra labor. The lposition of the wash-board or corrugatedL surface C' is inclined, with its rear end below the horizontal, ,thus fa'lvoring the feeding-operation of roller a. A frictionrpller,'m, is attached to the front end o the wash-board, or to the sides ot' tank A,'in a. suitable position, over which the clothing is lifted, from the bottom of said tank, thus'also favoring the feeding-operation. The position of the bottom of tank Ais inclining, the front end being the lowest, thus sliding the clothing back to the front of syaid tank, as-it falls from the Wash-board. The inclination oi' the bottom also serves to run all the water tothe front of said tank, thus requiring lesswater than would otherwise be necessary for the opera-tion. y
Having thus fully described our-said invention, what we claim, and desire to secure' by Letters Patent, is
1. We claim, in combination with wash-board G, (or other suitable surface,) the roller a, rotating and sliding at cach alternate stroke, substantially as described and for the purpose set forth.
2. We claim the combination of' the reciprocating rods d and d, hangers I1 and b', springs Y and V, ratchets e, and pawls I, with roller a and board C, all operating substantially as described and for the purpose set forth.
