Improvements in Wringing Machines.
I, JOHN WILLIAM FINEGAN, of Lowell, in the County of Middlesex, and State
of Massachusetts, United States of America, Gentleman, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to wringing machines, and among the objects in view is to
effect certain improvements in the manner of mounting and actuating the movable
roller.
The invention consists in the construction, arrangement and combination of parts
as hereinafter more fully described and claimed and as illustrated in the accompany-
ing drawings, wherein :"
Fig. 1 is a front elevation of this improved wringer.
Figs. 2 and 3, are respectively right and left end elevations.
Fig. 4 is a detail in plan showing the spring, the two bars and the screw.
Fig. 5 is an edge elevation of the operating gears adapted to be applied to the
device and portions of their support and shafts, the idlers being omitted.
Fig. 6 is a central vertical section of the gears shown in Fig. 5, gear Q being
omitted.
Fig. 7 is a front elevation showing a slight modification in the construction of the
machine.
Fig. 8 is a left end elevation of the same.
Fig. 9 is an underside view of the cross bar C.
Fig. 10 is a plan view of the plate P.
Referring to the said drawings, and more particularly to Figs. 1 to 6 inclusive,
the letter B designates the base from whose ends rise standards S, in bearings of
which is journaled the shaft L₁ of the lower roller L. A are L-shaped arms
pivoted at a to the standards S and carrying in their elbows bearings for the
shaft U of the upper roller U. T is a thumb-screw passing horizontally through
a cross-bar C (preferably of iron) having ears e, on one face, said bar connecting
the upper ends of the standards and bearing at its tip against a plate P, and E is
an elliptical or other shaped spring located between these ears of the plate and a
bar W which connects the upper ends of the arms A. The said bar W is formed
with sockets at its ends in which the ends of the said spring E are freely located as
fully shown in Fig. 4.
By these means the tension of the spring can be regulated as desired and such
spring turns the arms A around their pivots a, and forces the upper roller down
upon the lower with a yielding pressure.
The tip of the screw T bears against a plate P bearing against the centre of the
spring E while the ends of said spring have free movement in the sockets of the
bar Was heretofore described, so that no matter how the arms A. may rock,
the spring always bears properly against the bar.
His a crank handle keyed upon the shaft of the lower roller and this shaft
carries the main gear M which intermeshes with an idle gear 1 journaled on a
stub shaft i, on the right support S. The idle gear I intermeshes with another idle
gear G preferably somewhat larger than the first and which is journaled on one of
the pivots a, and this large gear intermeshes with the driven gear Q keyed on the
shaft of the upper roller U. The roller gears M and Q are of such size that they
will not strike each other when the rollers are pressed tightly together yet it will be
seen that the two idle gears cause the rollers to turn in opposite directions and at
the same rate of speed.
In Figs. 5 and 6 I have shown a system of power gears which may be employed

page_text: when it is desired to exert greater power in turning the rollers. In this case, the
handle H is connected to a small gear 1 which is loose on the shaft of the lower
roller, this gear meshes with a large gear 20 loose on the stub shaft i, this gear has
a small gear 3 fast on its hub which meshes with a large gear 40 that is secured to
the main gear M, and said main gear is connected by the idle gears (not shown
here) with the. driven gear Q on the upper roller in the same manner as above
described.
Thus it will be seen that the small gear 1 turns the large gear 20 more slowly
and the hub 3 of this gear turns the large gear 40 still more slowly, thus twice
decreasing the speed and hence increasing the power or purchase.
In the present case, I have shown the base B as having an inclined bottom b, and
as having raised edges R across its ends and across the lower edge of the bottom b,
the edge R across the lower side of the bottom being provided with an exit open-
ing X for the passage of water which may run off the rollers. The device is further
shown as secured to a table top t, by means of screw clamps e of the pattern shown
in Figs. 2 and 3, or that shown in Figs. 7 and 8.
The exit opening X stands beyond the edge of the table so that the water
running off the bottom may fall into a tub beneath.
In Fig. 7 I have shown the standards S constructed substantially in the shape
shown at a', whereby to form guides for guiding the cloth between the rollers.
N indicates a board secured to the frame in an inclined position transversely of
the machine and adapted to receive the cloth as it emerges from between the rollers
and thus pervent it from falling beneath the machine.
As shown in Fig. 10 the plate P is provided on one face with a projection p,
which presses against the spring 1 and said plate has projecting ends as shown
which loosely embrace the ears e, of bar C and thus is kept in place during its slid-
ing movements.
I do not limit myself to the precise details of construction herein described as
considerable change may be made therein without departing from the spirit of my
invention, and the shape, size and proportion of parts, together with their materials
and their ornamentation are matters of no importance with respect to the principle
of the invention.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is
1. In a wringer, the combination of a base, standards rising therefrom, a roller
journaled in said standards, a crank handle on the shaft of said roller, L-shaped
arms pivoted at one end to said standards and their other ends connected by a bar
extending transversely across the machine, an upper roller journaled in the elbows
of said arms, a cross bar connecting the top of the standards, a set screw extending
horizontally through said cross bar, a leaf spring having its ends freely engaging
the said bar extending transversely across the machine and arranged in a sub-
stantially-horizontal position to thereby normally force the roller carried by the
said L-shaped arms downward against the roller journaled in the standards, a plate
bearing against the central portion of said spring and having the tip of the screw
bearing against its face, and means for causing the upper roller to rotate simul-
taneously with and opposite to the direction of rotation of the lower roller,
substantially as described.
2. In a wringer, the combination of a base, standards rising therefrom and
provided with the guide portions a¹, as described, a roller journaled in said
standards, a crank handle on the shaft of said roller, L-shaped arms pivoted at one
end to said standards and their other ends connected by a bar extending transversely
across the machine, an upper roller journaled in the elbows of said arms, a cross-
bar connecting the top of the standards, a set screw extending horizontally through
said cross bar, a leaf spring having its ends freely engaging the said bar extending
transversely across the machine and arranged in a substantially horizontal position
to thereby normally force the roller carried by the said L-shaped arms downward
J

page_text: against the roller journaled in the standards, a plate bearing against the central
portion of said spring and having the tip of the screw bearing against its face, and
means for causing the upper roller to rotate simultaneously with and opposite to the
direction of rotation of the lower roller, substantially as described.
3. In a wringer, the combination of a base standards rising therefrom, a roller
journaled is said standards, a crank handle on the shaft of said roller, L-shaped
arms pivoted at one end to said standards and their other ends connected by a bar
extending transversely across the machine an upper roller journaled in the elbows
of said arms, a cross bar connecting the top of the standards, a set screw extending
horizontally through said cross bar, a leaf spring having its ends freely engaging
the said bar extending transversely across the machine and arranged in a sub-
stantially horizontal position to thereby normally force the roller carried by the
said L-shaped arms downward against the roller journaled in the standards, à plate
