IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 157,922, dated December 22, 1874 application filed October 31, 1874.

To all whom it may concern:

Be it known that I, THOMAS E. MCDON- ALD, of New Brunswick, in the county of Middlesex, in the State of New Jersey, have made certain Improvements in Machines for Washing Clothes, of which the following is a upon which the supporting-rollers of the washing-machine travel. B is a removable lower frame, containing a series of revolving rollers. b b are two transverse rollers on the-under side of and attached to the lower frame B, and travel upon ways a. b b b are transverse fluted revolving rollers in frame B. I)

b b are another series of transverse flutedrevolving rollers journaled in the same frame, and alternate with rollers b, but are out of line with them on their upper sides, as seen in Fig. 3. b is a bail at the forward end of frame B, to remove it from the water-box when necessary. The frame B is reeiprocated longitudinally on the ways a. O is the upper reciprocating removable frame, and has also a series of transverse rollers, c c, c c, and c". c c are the outside or end rollers, and are plain or smooth on their surfaces. 0 c are fluted intermediate rollers, and drop lower down than the end rollers c. c is the center roller in frame 0, on the same line with rollers c, and has a spiral groove cut around it from end to end. D is a lever, pivoted at d to a rod that passes transversely across the box A, and its bottom end freely entering into'and taking hold of staple d, that is fast in the end of frame B, as seen in Fig. 3, and by which means the said frame B, with its rollers, is reciprocated longitudinally. c is a removable rod, connected with the frame 0 at its forward end, at e,

and with the hand-lever D by one of a series of holes, 0, so that more or less throw may be given to frame G. F F are spring-arms, pivoted to the inside of the box A, at f, and carry roller f at their forward ends. f are springs secured longitudinally to the top of frame 0, and upon which the roller f bears as the frame 0 reeiprocates. g is a transverse rod connecting and holding the two spring arms F in position upon the journals f. h h are two pins that pass through holes h in the sides of the water-box, and bear upon the top of arms F, and by which the pressure on the frame 0 is regulated by adjusting pins h in different holes lb. The two frames B and O, with their rollers, are removable by disconnecting rod 0 from frame 0 and lever D, and turning up arms F with roller j.

When frame B is in position, and water in the box, the clothes or articles to be washed are placed upon the rollers of frame B. Then frame 0 is placed upon the clothes or article; the arm F, with its roller j", turned down, so that the rollers bear upon the springs f, and the pins h over the arms F, to give the necessary pressure, and rod 6 in place, by vibrating the upper end of hand-lever 1) longitudinally, will reciprocate the two framesone frame,B, in one direction, and frame 0 in the opposite direction-and at the same time the rollers in each frame, being out of line, will give to frame 0, in addition to a horizontal reciprocating motion, a rising-and-falling motion as it passes over the rollers of frame B. This rising-and-talling motion is due to the relative position of the rollers in frames B and G being out of line, or a part upon one line, and the others upon another line, which may be called zigzag in position, and its effects upon the articles being washed are much greater than if all the rollers in the two frames were in line with each other, as the rollers of the upper frame, in passing over the rollers, and the articles being washed on the lower frame, come in contact with much more of the surface of such articles than if the rollers in each frame were in line or on the same plane.

Having thus described my invention, what I claim is Q teases 1. In a washing-machine, the combination 3. In a Washing-machine, a reciprocating of the two frames B and (J, reciprocating in frame having two sets of rollers, 0 and 0, the opposite directions, with rollers, the axes of axes of which are in ditferent planes, substanwhich are in different planes, substantially as tially as and for the purpose described. and for the purposes described.

2. The combination of the lever D rod 6, THOMAS MCDONALD pressure-arms F, and resser-roller f, and Witnesses: springs f" with the frames 13 and O, substan- REUBEN Gr. VAN PELT, tially as and for the purpose described. EDWARD W. STRONG.
