WASHING- MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 674,661, dated May 21, 1901.

Application filed December 29, 1900. Serial No. 41,458. (No model.)

To all whom, it may conccrru Be it known that I, WILLIAM AGHESON, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in washing-machines, and has for its object the provision of novel means whereby the labor usually incident to washing is greatly reduced.

The herein-described invention consists of a receptacle having a washboard arranged at each end thereof, in combination with rolls mounted upon suitable bearings attached to the receptacle or washtub. One of said rolls is corrugated or fluted and mounted in a manner to obtain both a rotary and lateral movement, thereby rubbing and cleansing the clothes as they are passed through the rolls.

The invention further aims to construct a device that will be extremely simple in construction, strong, durable, and comparatively inexpensive to manufacture.

With the above and other objects in view the invention consists in the novel combination and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claim.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification,and wherein like numerals of reference indicate corresponding parts throughout the several views, in which Figure 1 is a front view of my improved tub, at each side thereof, is a housing 4, and in each of these housings is arranged a bearing-block 5, held on a shaft 5,which is threaded in the cross-bar 6 at the top of the housings. Aspring 7 is arranged on the shaft 5 bet-ween the bearing-block 5 and the crossbar 6. Journaled in the housings 4 at the upper edge of the side pieces of the washtub is a shaft 12, upon which is mounted a roller 13, having a smooth or plain exterior surface or periphery. On one end of the shaft 12 is mounted an operating wheel 15, having a handle 16, and on the opposite end said shaft carries a cog-wheel 14. A shaft Sis arranged in the housings 4 in vertical alinement With the shaft 12 and has mounted thereon a corrugated or fluted roller 6. This shaft 8 at the ends of the fluted roller 6 is engaged by the bearing-blocks 5, and it carries on its one end a cog 9 to mesh with the cog 14, whereby the two rollers may be rotated in unison. The fluted roller is cut at its ends, so as to form cams 1O 10, oppositely disposed to each other-that is, so placed that during the revolution of the roll one of these cams will be at the lower side of the roll and the other will be at the upper side thereof. Each bearing-block carries on its inner face a projection 11, and these projections engage alternately with the cams 10 10, sothat during the rotation of the fluted roller a movement longitudinal to its axis will also be imparted thereto, such movement, however, not being sufficient to disengage the cog 9 from its mesh with the cog 14. This longitudinal movement imparted to the roller 6 simultaneously with its rotation causes the ribs 7 of said roller to have a squeezing or scraping action upon the clothes as the latter are passed between the rollers 6 and 18. The housings 4 are suitably braced near their upper ends by cross-pieces 17, and braces 18 are arranged between these cross-pieces l7 and bed-plates 19,the latter being secured between the housings at apoint where the upper face of the same is on the same plane or about on the same plane as the top of the roller 13, so as to act as a support for the clothes as the latter are inserted into the pass between the two rollers. Suitable cleats 20 are attached to the sides of the washtub to receive and hold in position the lids or covers 21', so that the said tub may be closed at each side of the housings when desired.

In operation it will be observed that as the rollers are rotated the cam ends of the fluted roller 6 Will alternately engage the projections 11 of the bearing-blocks 5, so as to impart a reciprocating or to-and-fro movement to the fluted roller simultaneously with its rotation, giving in addition to the pressing action of this roller a scraping action upon the clothes, so as to more elfectually cleanse the same than would be possible by the pressing action alone. The braces 18 at the front and rear of the rollers serve to confine the clothes within a specified area and prevent their spreading beyond the ends of the rollers, where parts thereof would not be subjected to the action of the rollers. The cams 1O being oppositely disposed on the ends of the roller 6, the wheels 9 14 are retained in mesh to a greater or less extent at all times,as when the cam 10 is in full engagement with the projection which it engages the cam 10 will be at the lower part of the roller and the end of the roller proper will be against the projection engaged by the cam 10. As the roller continues to revolve, however, and as the cam 10 passes out of engagement the cam 10 enters into engagement with its respective proj ection,continually imparting a reciprocatory or to-and-fro movement to the roller 6, but

retaining at all times a sufficient mesh of the cogs 9 and 14: to accomplish the driving of the rollers.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a washing-machine, a tub or receptacle, housings on each side thereof, bearing-blocks movably mounted in said housings and having inclined integral projections thereon, adjusting-rods threaded on one end and engaging the said bearing-blocks and the housings, springs surrounding said rods between the housings and the bearingblocks, a shaft mounted in the said tub or receptacle, an operating-wheel on one end thereof, a cog-wheel 0n the other end, a smooth roller mounted on said shaft, in combination with a shaft mount ed in the said bearing-blocks, a fluted roller carried by the shaft, a cog-wheel on one end of said shaft, said cog-wheel adapted to intermesh with the said cog-wheel of the firstnamed shaft, and oppositely-disposed cams made integral With the fluted roller for alternate engagement with the said projections on the bearin g-blocks,substantially as described. In testimony whereof I aflix my signature in the presence of two witnesses.
