This invention relates to a washing machine of improved construction and it consists
in the various features of improvement more fully pointed out in the claims.
In the accompanying drawing:
Fig. 1 is a side elevation of my improved washing machine.
Fig. 2 a cross section on line x, x, fig. 1.
Fig. 3 is a longitudinal section of the machine without the power driving mechanism.
Fig. 4 an enlarged section through one corner of the suds box.
Fig. 5 a section on line y, y, fig. 4.
Fig. 6 a section on line z, z, fig. 4 and
Fig. 7 a detail view of the coupling on band e.
The letter a, represents a suds box made of cylindrical form and supported upon
legs b. At the top, a central piece is cut out of the upper staves a¹, of the suds box,
to form the proper opening which may be closed by a cover or covers c. d, d, are the
two heads of the suds box, received by grooves d', as shown. The suds box is
encircled by the metal bands e, which may be readily adjusted in case the suds box
expands or contracts. To this effect, the ends e¹ of bands e, are turned outward and
are perforated for the reception of a screw bolt e². By tightening up a nut e³, upon
this bolt, the ends of the band may be drawn together to any desired extent.
To the heads d, are secured the journal bearings f, that project into the suds box
and receive the journals 9', of an oscillating frame g, to which is pivoted the dasher
roller g. The frame may be oscillated by hand or by steam according to the size of
the machine. If driven by hand, motion is imparted to a suitable hand bar 9. lf
driven by steam, I prefer to employ the mechanism more fully shown in figs. 1 & 2.
Here the power pulley h, is provided with pitman ', that rocks a lever ², pivoted
to head d. The upper end of lever h, is forked as at ³, and embraces a bar g*,
projecting laterally from frame g. It is evident, that the revolution of pulley h will,
through pitman and lever ³, oscillate the frame g, and thus cause the roller g³, to
travel back and forth over the inner surface of the suds box.
The motion of the roller g³, has a tendency to create a corresponding motion of the
water up and down the surface of the suds box. To break the alternate streams of
water, I secure to the suds box two ledges i, i, extending from head to head. These
ledges are located a short distance beneath the top opening and are of the form shown
in fig. 2. That is to say, they gradually increase in thickness from the bottom
upwards and at the top they have a downwardly depending nose . By this form,
the water which would otherwise follow the contour of the suds box, is broken, to fall
upon the wash, in a whirling motion. Thus the effectiveness of the machine is
increased and splashing is prevented.
The water is admitted and drawn from the machine by a pipe j, having an inlet cock j¹
and an outlet cock. The pipe enters a crescent-shaped space formed at the bottom of
the suds box by an upper false bottom k. In this space, the water spreads laterally and
enters through perforations m¹, into channels m, formed within the heads d. The
channels m extend in parallel direction, up about one third the height of the heads and
open into the suds box, by means of narrow slits m². The water is admitted and with-
drawn through these slits and will be thus spread over a large surface in a well divided
body. Of course, the channels and slits are formed in each of the two heads, so that the
water acts uniformly at both ends of the machine. The advantage of this construction

that no suction will be created, which would have a tendency to draw the wash to the
mouth of the pipe and thus clog the same.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination of cylindrical suds box a, having heads d, and bearings f, with
an oscillating frame g, journalled therein and with roller g³, pivoted to said frame,
substantially as specified.
2. The combination of cylindrical suds box a, having the upper staves a¹, of reduced
length, with bands e, surrounding the suds box and with heads d, bearings f, oscillating
frame g, and a roller g³, pivoted to said frame, substantially as specified.
3. The combination of cylindrical suds box a, having upper staves a¹, of reduced
length with bands e, having outwardly projecting ends e¹, bolts e³, and nuts e³, and
with the heads d, bearings f, and the roller-carrying frame g, journalled in said
bearings, substantially as specified.
4. The combination of cylindrical suds box a, with ledges i, extending through the
suds box, said ledges increasing in thickness from the bottom up and having down-
wardly depending noses, and with heads d, bearings f, and the roller-carrying
frame g, journalled in said bearings, substantially as specified.
5. The combination of suds box a, having heads d, bearings f, and roller-carrying
frame g, having bar g, and journalled in said bearings, with pulley h, pitman 7, and
lever, having forked end ³, that engages bar 9*, substantially as specified.
6. The combination of suds box a, with false bottom k, and heads d, having
channels m, that open into the suds box above and below the false bottom k,
substantially as specified.
7. The combination of suds box a, with false bottom k, heads d, having channels m,
perforations m¹, and slits m², and with pipe j, entering beneath the false bottom,
substantially as specified.
