SPECIPICATION forming part of Letters Patent No. 327,059, dated September 29, 1885. H

Application filed April 3, 1884. (No model.)

To all whom it'may concern/.-

Be it known that I, HENRY O. BARNARD, a citizen of the United States, residing at Charles ton, inthe county of Goles and State of Il-linois, have invented certain new and useful Y Improvementsin Washing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of washjug-machines in which an agitator is alternately reciprocated in a rotary direction by means of gear mechanism acting upon the shaft of the agitator.

In the drawings, Figure l is a side elevation of a washing-machine embodying myimprovements. Fig. 2 is a top view of the same. Fig. 3 is a vertical transverse sectional view thereof. Fig. 4 is an inverted plan view showing the under side of the top or cover with the agitator in position. Fig. 5 is a top or plan view of the agitator. Fig. 6 is a detail perspective View of the nut which secures the agitator to its shaft. Fig. 7 is a detail sectional view.

Corresponding parts in the figures are denoted by the same letters of reference.

Referring to the drawings, A designates the box or body of myirnproved washing-machine, which may be of any suitable construction, but is preferably rectangular, and is provided with a flange or shoulder, a, formed around its top opening and adapted to support the cover or top piece, B. The cover is hinged to the top of the box at one side, as shown at O G, and is adapted to be retained down in position at the other side by means of plates or buttons D D, pivoted to the top of the box A.

A suitable re-enforcing board or plate, E, is secured to the under face of the cover B, which serves to strengthen the said cover and form a shoulder, e, which corresponds to the flange a, and forms a neat joint therewith.

Fis a perforation, which is centrally provided through the cover, and is formed with a circumferential shoulder, f, at its top. This perforation receives a corresponding tubular bearing-piece, G, which extends to the under side of the cover, and is provided with an annular top flange, g, which is received by the shoulderf, and serves to secure the bearingpiece in position.

H designates the agitator-shaft, which pro- 'jects through the bearing-piece G, and has Its bearing therein. At the top end of this shaft is fixed a horizontal pinion, I, that is preferably keyed upon the said shaft by means of a transverse pin, J, passing through the hub of the pinion under its teeth and through a groove, h, in the face of the shaft. The tee'ah of the pinion are preferably extended down over its hub portion, as shown at i, at the side through which the'pin Jpasses, to strengthen the pinion and prevent accidental breaking of the same by the jar of its operatinggear.

Two upright standards, K K, are secured upon the cover on the same transverse plane and at opposite sides of the pinion I, in which are provided bearings for a transverse horizontal rotary shaft, L, having an operatlng crank or handle, M, at its end.

On the shaft L are secured two disks, N N, by means of set-screws n at, these disks being arranged to be on opposite sides of the pinion I, and each having a segmental series of teeth, if, on their inner faces. The disks N N are adjusted upon their shaft in such a manner that the smooth portion of the face of one disk will be opposite the toothed portion of the face of the other disk, whereby when one of these vertical disks is in engagement with the horizontal pinion the other will be out of engage ment. By this arrangement of gears it will be obvious that as the shaft L is rotated and carries the vertical semi-toothed disks the teeth upon the said disks will alternately engage with the pinion and will reciprocate the same in a rotary direction as the shaft and vertical disks move upon their continuous rotary movement.

Preferably about one-half of the inner faces of the disks N N are provided with teeth, and by means of the set-screws a n the said disks can, when desired, be adjusted to and from the pinion; or they may be adjusted in a rotary direction to regulate the relative positions of the teeth upon the two disks.

Upon the screw-threaded portionh of the shaft H a nut, O, is adjusted up against the lower end of the bearing-piece to assist in retaining the shaft from vertical displacement.

Below this nut the shaft is provided with a shoulder, as shown in Fig. 7, and rectangular l3O1131O11]1/ ,Wl1l(3h receives the correspondingly- 'ectangular opening in the head 1) of a plate,

P, which carries the agitator-arms. The arms Q are secured to the under face of the said plate by means of screws q or other suitable fastening devices, and they extend radially, and are provided at their outer ends with the fingers g. The inner ends of the arms Q do not extend entirely to the shaft, so that an .open space, R, is formed to acoon'nnoda'te a nut, S, which is adjusted upon the projecting screw-threaded end If of the shaft to retain the agitator upon the latter. This nut is provided with a transverse groove, 8, so that it may be to effect its adl. As an improvement in washing-machines, the combination, with the cover having the bear ng-piece set therein, of the agitatorshaft pass ng through said bearingpiece and com-' prlsingthescrew-threaded portionh,thesh0ulder and rectangular portion h, and the proarm disposed to form the central space, R, and

the grooved nut, substantially as set forth.

2. As an improvement in Washing-machines, the combination of the bearing-piece, the agitator-shaft passing through the same and comprising the screw -threaded portion h, the shoulder and rectangular portion h, and the projecting screw-threaded end h the operating'pinion, the retainingnut set upon the portion h, the agitator comprising the head-plate having the head 19 set upon the portion h and having the radial arms disposed to form the central space, R, between their adjoining ends. and the grooved nut set within this space upon the end h substantially as and for thepurpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
