WASHING-MACHINE.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed May 27. 1905. Serial No. 262.666-

To all whom it may concern; Be it known-that I, SAMUEL MCGRANAHAN, a citizen of the UnitedStates, residing at Davenport, in the county of Scott and State of Iowa, have invented new and useful Improvements in Washin-Machines, of which the following is a speci cation.

' This invention relates to improvements in washing-machines of the class constructed and designed to impart a reciprocal rotary" I movement to the dasher.

The object of the invention is to provide a durable and simple and easily-operated device of the class described.

With this object in view the invention consists in certain details of construction and combinations of parts, which will be described in connection with the following specification,

with reference to the accompanying drawings, in which I Figure 1 is a view in side elevation of my improved washing-machine. Fi .2 is a section on the line 2 2 of Fig. 1. an Fig. 3 is a partial section on the line 3 3 of Fi 2.

Referrin to the drawings, w erei-n like numerals reference indicate corresponding parts throughout the several views, my improved washing-maching comprises the usual tub 1,' which may be of any material or see- .t ional dimensions desired, preferably supported on legs 2 and closed at its u er end ya removable cover 3, all of whic parts may be constructed and arranged as desired, as the particular construction of the same forms no material part of the present invention.

ings 14, fixed on the cover and 4 represents a bracket secured to the cover 3,, atone side of the center thereof, and ineluding spaced vertical arms 5, formed at the upper ends with bearings 6.- A power-shaft 7 is mounted for revolution on the bearings 6, bein provided at the outer end with a crankhandle 8 and at the inner end with a-gear 9, av

clearly illustrated in Fig. 1.

and centrally of the housing, sleeve below the teeth fitting intermesh wi h the ear, said pinion bein preferably protected y a shield 16, extendinglaterally from meet the arms of the bracket 4.

17 re resents what I term a gear-housing secured centrally of the cover 3 and formed with a depending boss '18 to engage the wall of a circumferential opening 19, centrally formed in said cover. The housing is referably-of elongated oval shape and wiolly closed, except on the side next the gear 9, be

ing there provided with an elongated longitudinally-arranged opening 20, practically coextensive with the vertical wall of the housing. The upper and lower walls of the opening 20 are formed with ribs 21, arranged in vertical alinement and designed to engage with recesses 22, formed in the upper and lower surfaces of a rack-bar 23, whereby said rack-bar is guided in longitudinal movement by the ribs. The lower wall of the housing. is extended beyond the rib 21 at 24 to rovide anextended bearing for said rackar, as The rack-bar extends within the housing and is provided witha longitudinally-arran ed row of teeth 25, arranged to mesh wit the teeth 26, formed on a sleeve 27, arranged vertically the body of'the revolubly within the boss 18, the body of the sleeve above the teeth projecting through an opening 28, formed in the upper wall of the housing, said upper wall being preferably thickened at the bearing-point to properly support the sleeve. The rack-bar is provided at one end with a verticallyextending arm 29, connected, through the medium of a link 30, with the gear 9, being preferably connected adjacent the periphery of said gear, whereby revolution thereof will impart areciprocating movement to the rack-bar.

31 represents the dasher,-arranged within the tub l and of any preferred construction. A dasher-shaft 32, square in cross-section, projects vertically from the dasher 31 and slidably enga es a square socket 33, formed centrally and vertically of the sleeve 27, whereby said dasher is freely movable in a vertical direction to accommodate itself to thp) quantity of clothes contained within the u Assuming the parts to be constructed and arranged as described,v the operation of the crank 8 will, through the medium of the gear 9, rapidly reciprocate the rack-bar 24. The reciprocation of the rack-bar rapidly revolves the sleeve 27, with the eilect to impart the necessary rotation to the dasher.

ously resulting from the high momentum of the fly or balancewheel.

It will be noted that the dashe-r-rod 32 is freely movable vertically within the sleeve 27, whereby the dasher may accommodate itself automatically to the quantity of clothes within the tub, and will readily yield in an upward or downward direction under the influence of the operating mechanism to avoid breakage in. the event of a comparatively large accumulation of clothes immediately beneath the dasher at any time in the operation of themachine.

Having thus described the invention, what is claimed as new is- 1n :1 washing-machine, the combination with a tub and a cover therefor, of a housing mounted upon said cover and provided with a bushing upon its lower side and a boss upon its upper side, a sleeve journaled in said bushing and hoss, said sleeve being provided with a rectangular opening extending longitudinally therethrough, a rectangular agitatorshait mounted in said opening, an agitator mounted uponsaid shaft, said housing being further provided with a horizontal slot, ribs upon the housing extending into said slot, a

rack-bar movahle within said slot and provided with recesses engaging said ribs, gearteeth upon said sleeve engaging the rack-bar, an upright upon the outer side of said rackhar, a crank-wheel mounted upon thecover. a link connecting. said crank-wheel with said upright and means to rotate said crankwheel.

ln testimony whereof I allix'my signature in presence of two witnesses.
