page_text: pivots D, D, have a bearing; G is a large corrugated roller arranged
underneath the rollers A, A, and having a bearing in the standards F, F.
This roller G is left plain or uncorrugated at each end for the distance
of about one inch in order to prevent the rollers A going into the
grooves when the machine is running empty; H is a..crank by which
the roller G is rotated; K, K, are two parallel boards set vertically in
the standards F, F, the ends P being left long enough to admit of being
cut to fit a tub; L, L, are pieces attached to the inner side of the
tub so that the machine may be arranged in the latter by setting
the ends of the boards K, K, over the said pieces, as shown in
Figure 1.
In order to prevent the machine from sinking too low the bottom
of the pieces L, L, are provided with lateral projections I, I; M is
a bent wire rod, the ends of which are hooked into the pieces B, B',
respectively, as shown in Figure 2; N is a coiled spring hooked on
the central part of the rod M, and extending downward between the
boards K, K, and fastened by the pin O; Q, Q, are holes in the boards
K, K, into either of which the pin O may be inserted so as to regulate
the tension of the springs N, N, as may be required.
Having described the nature of the said Invention, and in what
manner the same is to be performed, I declare that what I claim as
new and desire to secure by Letters Patent is,—
1st. In combination the vertically slotted standards F, F, yielding
segmental pieces B, B¹, hinged together at O, and the piece B' provided
with the rib or pivot D, the small rollers A, A, and large corrugated
roller G, all constructed and arranged together substantially as and for
the purposes specified.
2ndly. In combination, two or more segmental pieces B hinged
together by means of one or more overlapping plates at C (the single
or central plate R being provided with the rib or pivot D), rollers A, A,
large corrugated roller G, and vertically slotted standards F, F, all
constructed and arranged together substantially as and for the purpose
specified.
