PROVISIONAL SPECIFICATION.
An Improvement in Machines for Scutching and Cleaning Fibrous
Stems and Leaves.
I, GEORGE MORGAN LANE of No. 147 Leadenhall Street in the County of
London, Civil Engineer do hereby declare the nature of this invention to be as
follows:-
In many machines for scutching and cleaning fibrous stems and leaves, a table is
moved to and fro advancing the stems or leaves laid on it to be acted on by
revolving beaters, and withdrawing them. The stems or leaves have to be held
firmly between the jaws of a clip near the end of the table, the upper jaw being
usually pressed down by weights or springs. My invention relates to means of
automatically opening this clip when the table reaches the end of its back stroke so
that the material that has been acted on can at once be withdrawn and fresh
material can be fixed on the table. For this purpose I fix the upper jaw of the
clip on radial arms pivotted to the table and I provide on these arms rollers, which
as the table is approaching the end of its back stroke run up inclined rails fixed to
the framing, the upper jaw being thereby lifted, to allow of the material being
withdrawn and of fresh material being put in its place, this being held by the
descent of the jaw as the table begins its forward stroke.
Dated this 2nd day of February 1892.

COMPLETE SPECIFICATION.
An Improvement in Machines for Scutching and Cleaning Fibrous
Stems and Leaves.
I, GEORGE MORGAN LANE of No. 147 Leadenhall Street in the County of
London, Civil Engineer, 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 :-
In many machines for scutching and cleaning fibrous stems and leaves, a table is
moved to and fro advancing the stems or leaves laid on it to be acted on by
revolving beaters and withdrawing them. The stems or leaves have to be held
firmly between the jaws of a clip near the end of the table, the upper jaw being
usually pressed down by weights or springs. My invention relates to means of
automatically opening this clip when the table reaches the end of its back stroke
so that the material that has been acted on can at once be withdrawn and fresh
material can be fixed on the table. For this purpose I arrange the clip as I shall
describe referring to the accompanying drawings.
Fig. 1 is a side view and Fig. 2 is a half plan.
I joint the upper jaw A of the clip to radial arms B jointed at C to the lower
jaw D and I provide on these arms rollers E which as the table is approaching the
end of its back stroke run up inclined rails F fixed to the framing, the upper jaw A
being thereby lifted, to allow of the material being withdrawn and of fresh material
being put in its place, this being held by the descent of the jaw as the table begins
its forward stroke.
As shewn in the drawings the table consists of the lower jaw D at each end of
which are fixed guides G between which the upper jaw A slides. To the lower

page_text: jaw are attached arms H connected by a cross bolt K by which the clip is
retracted.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In machines for scutching and cleaning fibrous stems and leaves, in combination
with a clip having its upper jaw attached to lever arms jointed to the lower jaw,
rollers on those arms and stationary inclines along which they run as the clip is
completing its back stroke, substantially as described.
Dated this 1st day of November 1892.
