PROVISIONAL SPECIFICATION.
Certain Improvements applicable to Screw Gill Machinery.
We, WILLIAM HORSFALL GREENWOOD, Commission Wool Comber, and
FREDERICK FARRAR, Manager, both of Spring Mill Street, Bradford, in the
County of York, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in that class of screw gill machinery in
which a cross bar is employed to keep the fibres in position as they are fed into the
gills or fallers and prevent them being lifted instead of penetrated by the fallers as
the latter are successively brought into operation upon the fibres. This cross bar
has been a cause of frequent and in some cases fatal injury to the attendants of this
class of machinery owing to the liability of the attendant's hand being drawn
underneath it and the pins of one or more of the fallers consequently driven through.
or into the hand, and the object of this invention is to obviate this danger.
For this purpose instead of rigidly fixing said cross bar we make it of sufficient
weight to answer the purpose for which it is employed but otherwise leave it
perfectly free to be lifted in case of emergency. And we provide suitable seats,..
shoulders, stops or guides adapted to prevent the cross bar being moved horizontally
to a detrimental extent.
Dated this 22nd day of January 1894.

Certain Improvements applicable to Screw Gill Machinery.
We, WILLIAM HORSFALL GREENWOOD, Commission Wool Comber, and
FREDERICK FARRAR, Manager, both of Spring Mill Street, Bradford, in the
County of York, 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 improvements in that class of screw gill machinery in
which a cross bar is employed to keep the fibres in position as they are fed into the
gills or fallers and prevent them being lifted instead of penetrated by the fallers as
the latter are successively brought into operation upon the fibres. This cross bar
has been a cause of frequent and in some cases fatal injury to the attendants of this.
class of machinery owing to the liability of the attendant's hand being drawn
underneath it and the pins of one or more of the fallers consequently driven through
or into the hand, and the object of this invention is to obviate this danger.
For this purpose instead of rigidly fixing said cross bar we make it of sufficient
weight to answer the purpose for which it is employed but otherwise leave it
perfectly free to be lifted in case of emergency.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification in which similar letters of reference indicate similar parts in each
of the figures.
Figure 1, represents a plan view of such parts of a screw-gill box as are-
necessary to illustrate the application of our improvements thereto.

page_text: Figure 2, represents a cross section on the broken line a, b Figure 1. Figure 3,
represents a side view of the same.
The portions of the side frames A, A shown as well as the travelling screws B the
saddles C, and the fallers D are of ordinary construction. A small bracket E is
secured to each side frame by the screw e and the cross bar F is loosely supported
by these brackets. The lips on the front of the brackets and the pieces O
forming the back of the brackets keep the cross bar in position laterally and
prevent it moving with the fibres G in the direction of the arrow Figure 1
and the shoulders; on the bar keep it from moving longitudinally. At the same
time it will be readily seen that the bar is perfectly free to be lifted in case
of emergency. The cross bar is preferably made fairly broad to still further
reduce the liability of the attendant's fingers being accidentally passed sufficiently
far underneath to be injured by the fallers. The ends F2, F3 of the cross bar are
preferably cranked upwards sufficiently to clear the screws B.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :
1. A cross bar for a screw-gill machine constructed and arranged to be free to be
lifted in case of emergency, substantially as herein shown and described and
illustrated in the accompanying drawings.
2. The combination of the cross bar F having shoulders j, j, of the brackets or
their equivalent E, E loosely supporting the cross bar, and provided with lips i
substantially as herein shown and described.
