ABRAM P. QUAOKENBUSH, OF BROOKLYN, NEW YORK.

IMPROVED WASHING-MACHINE.

Specification forming part of Letters Patent No. 33,449, dated October 8, 1861.

To all whom it may concern.-

Be it known that I, ABRAM P. QUACKEN- BUSH, of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Washing-Machines; and I do hereby declare that the followingis a full and exact description of the same, reference being had to the accompanying drawing, and to the lettersdenoted thereomforming a part of this specification.

The drawing is avertical section through the machine. k

My invention consists in the construction and use of a revolving rubber in the periphery of which fixed cylinders and freely-revolving rollers are distributed, as shown below in combination with a concave composed of freely-revolving rollers.

Toen-able others skilled inthe art to make and use ,my invention, I will proceed to describe its construction and operation by the aid of the drawing.

The tub or fixed portion of the machine is composed of two plane heads A, a semi-cylin drical concave base with nearly perpendicular sides a, and suitable supporting-legs.

B is a shaft mounted in the heads A, and provided with a crank on one of its overhanging ends for turning it. This shaft is mounted in slots in A, as shown by the dotted lines, and is carried in slides (not represented) sothat it is free to rise and sink without allowing the escape of much water. Just within a are mounted freelyrevolving` rollers D, each roller extending the whole distance from one of the heads A to the`other.

On the shaft B is fixed a pair of wheels C, just within each head A. These wheels are of equal size and of a diameter proportioned to d and to the series of rollers D, as represented. Iiour cylinders c c c c, proportioned and located as indicated, are firmly fixed one end to one of the wheels C and the other end to the similar wheel Con the-otherside ofthe machine. These cylinders thus extend across the interior of the entire machine and revolve with B, but do not revolve on their own axes, being xed rigidly to C. It Will be observed that their extreme outer sides protrude beyond the periphery of C, as represented.

E E, dac., are rollers mounted in C, each equal in diameter to c, and protruding to an equal extent therewith, but free to revolve each on its own axis. There are two of these freely-revolving rollers E for eacliiixed roller c.

In operating my machine the clothes and water are placed in the machine and the shaft- B turned by hand to tumble and wash them. The clothes are simply compressed by each passage of a loose rollerE, butare compressed and also turned or changed in position by each passage of a similar cylinder c.

My machine attains a high degree of perfection in the result and great rapidity in its operation and involves but a small cost, bulk,

and weight of machine.

I am aware that revolving wheels and roll-- ers have been used before in many varieties of washing-machines, and that many patented arrangements have produced some of the effects produced by mine; but the necessary cost ot' some has limited their usefulness while the bul-k and weight of others have been objectionable, and I am not aware that any have been equal to mine in fulfilling the many conditions required in these important machines.

Having now fully described my invention,

what I claim as new therein, and desire to secure by Letters Patent, is-

The construction and use in washing-machines of a rubber or wheel having fixed cylinders c, equal in size and in distance from the center tothe rollers E, and alternating with the latter or with pairs or triplets thereof, as shown, in combination with" rollers D, so mounted as to form a concave, for the' purpose hereinabove set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
