F. W. WITTING, OF YORKTOWN, TEXAS.
IMPROVEMENT IN COTTON-PRESSES.
Specification forming part of Letters Patent No. 19,399, dated February 16, 185S.To all whom it many concern:
Be it known that I, F. W. WITTING, of
Twelve-Mile Coletto Gin, (Yorktown P. O.,)
in the county of De Witt, and State of Texas,
have invented a new and useful Improvement
in Cotton-Presses; and I do hereby declare
that the following is a full, clear, and exact
description of the same, reference being had
to the annexed" drawings, making a part of
this specification, in which-
Figures 1 and 2 are vertical central sections
of my improvement, the two planes crossing
each other at right angles.
Similar letters of reference indicate corre-
sponding parts in the two figures.
This invention consists in a peculiar ar-
rangement of means for compressing the cot-
ton, both vertically and laterally, by one and
the same application of power. This end is
attained by having one side of the press-box
made movable, or so arranged that it may
slide, and having toggles connected with it,
the toggles being attached to the rods and so
arranged with a follower connected with a
power-screw that as the follower descends it
will automatically engage with the mechan-
ism alluded to and move the side of the box
inward, compressing the cotton laterally, the
side being after a certain time automatically
disengaged from the follower,which then acts
upon the cotton, compressing it vertically.
To enable those skilled in the art to fully
understand and construct myinvention, I will
proceed to describe it.
A represents a suitable framing, in which a
press-box, B, is secured; and C is a screw
which passes vertically through cross-ties a b
in the upper part of the framing.
D is a nut which is fitted on the screw C
between the cross-ties a b. This nut has two
bevel-wheels attached to it-one, c, at its up-
per and the other, d, at its lower cud-the wheel
c being considerably larger than the wheel d.
The nut D has within it two rings, e e, pro-
vided with friction-rollers f, one ring being
fitted against the upper cross-tie, a, and the
other resting on the lower cross-tie b. (See Fig.
1, in which the ring and rollers are shown.)
This arrangement is to diminish friction, and
is a well-known mechanical device.
To the lower end of the screw C a follower,
E, is attached, and F is a horizontal shaft
placed in the upper part of the flaming, andhaving a driving-pulley, g, on its outer end.
The inner part of said shaft has its bearing
in a lever, h, by which it may be raised and
lowered, and by means of two pinions, ij, upon
it thrown in gear with either the upper or
lower wheel of the nut D.
The side k of the press-box B is made mov-
able or allowed to slide laterally in either di-
rection, (indicatedby the arrows 1 and 2,) said
side having horizontal bars 1 1 attached to it-
one at its upper and the other at its lower end.
To each end of the bars 1 l there is attached
a metal bar, mn, and consequentlythere are two
bars m at each end of the press-box. These
bars rest on guides or cross-pieces in the fram-
ing, and to the front part of each bar m one
lever, n, of a toggle is pivoted, the other levers,
o, of the toggles being pivoted to the framing,
as shown at p. It will be understood, there-
fore, that there are two toggles at each end of
the press-box, and the toggles at each are con-
nected by a vertical bar, G.
To the bars G, and near their lower ends,
rods I I are attached-one to each bar. These
are somewhat curved, and each is provided
at its upper end with two horizontal projec-
tions, q r. The upper projections, q, are con-
siderably longer than the lower ones, r, and
the space between the two is about equal to
the thickness of the follower E. (See Fig. 2.)
The operation is as follows: Suppose the fol-
lower E to be in an elevated state, as shown in
black, Fig. 2. The cotton is placed in the
box B and motion is given the nut Dby throw-
ing the pinion i in gear with the wheel c. The
projections r on the upper ends of the rods I,
when said rods are elevated, project under-
neath the ends of the follower E. The nut D
is now rotated in the direction of arrow 3,
and the screw C and follower E are forced
downward, the follower E depressing or forc-
ing down the bars G,which actuate the toggles
and cause the side k of the press-box to be
moved inward, as indicated by arrow 2. As
the bars I I descend, they are gradually forced
outward in consequence of springs ax,which
are attached to their inner sides, bearing
against the ends of the press-box, and by the
time the toggles are fully extended and the
side k pressed or forced inward the required
distance the bars I I are forced outward to
such a distance that the projections r are be-
yond the ends or edges of the follower. The
