PROVISIONAL SPECIFICATION.
Improvements in Gill Boxes for Preparing Wool, Flax, Jute, Hemp,
Silk, and other Fibres.
We, JOSEPH SMITH, of Kensington Works, Halifax, in the County of York,
Machine Wool Comber, and WILLIAM HOLDSWORTH, of Mount Street, Halifax,
aforesaid, Machine Comb Maker, do hereby declare the nature of this invention
to be as follows:-
The object of our invention in the above named machine is to provide means
to guide the fallers in their descent from the upper saddle to the lower saddle
and to prevent them re-bounding and becoming locked and also to force each
faller as it drops upon the lower saddle into a positive position to be taken hold
of by the lower screws, and this we propose to do by dispensing with the guide
spring at present in use and using instead thereof a new form of vertical bar, the
upper end of which is made with an inverted spring leg. Each end of the faller
has a groove formed in it opposite to the spring leg as is usual, and as each faller
arrives at the end of the top screw and saddle, it is guided accurately down to
the bottom saddle and whilst the faller is being driven by the cam it compresses
the spring leg, but as soon as the said faller has got below the upper saddle, the
spring leg is released and it immediately springs forward and forces the faller
forward on to the lower bed into a position under the upper saddle whereby it
cannot re-bound as is common with this class of machine nor can it become locked.
Dated this 2nd day of December 1897.

Improvements in Gill Boxes for Preparing Wool, Flax, Jute, Hemp,
Silk, and other Fibres.
We, JOSEPH SMITH, of Kensington Works, Halifax, in the County of York,
Machine Wool Comber, and WILLIAM HOLDSWORTH, of Mount Street, Halifax,
aforesaid, Machine Comb Maker, 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: -
The object of our invention in the above named machine is to provide means
for guiding the fallers in their descent or ascent from one saddle to the other
saddle and to prevent them rebounding or becoming locked, and also to force
cach faller whether upon the lower or upper saddle into a positive position to be
taken hold of by either top or bottom screws and out of the way of the cams, and
this we propose to do by dispensing with the guide spring at present in use,
and using instead thereof a new form of vertical bar, one end of which is bent and

in it, opposite to the spring leg as is usual, and as each faller arrives at the end
of say the top screw and saddle, it is guided accurately down to the bottom saddle
and whilst the faller is being driven down by the cam it compresses the spring
leg, but as soon as the said faller has got below the upper saddle or above the
upper saddle, the spring leg is released and it immediately springs forward and
forces the faller forward on to the lower saddle or on to the upper saddle into such
a position that the faller cannot rebound as is common with this class of
machine, nor can it become locked.
In the accompanying drawings illustrating our invention, Fig. 1 is front
elevation of part of a gill box, shewing our improvement applied thereto and
Fig. 2 is detail shewing the relative position our improved guide spring occupies
with respect to the upper and lower saddles.
Referring to the drawings A is the framework of the machine, B the upper
screw for working the fallers 1) forward, and the lower screw employed to
bring the fallers backward, E is the upper saddle or bed upon which the upper
fallers travel, and F is the lower saddle or bed upon which the lower fallers travel,
all of which parts are of ordinary construction and form no part of our invention.
The object of this our invention is to provide means to guide the fallers in their
descent from the upper saddle E, see Fig. 2, to the lower saddle F, and to prevent
said fallers from rebounding and becoming locked and also to force each faller
as it drops upon the lower saddle, into a positive position to be taken hold of by
the lower screws C, and this we accomplish by dispensing with the guide spring
at present in use and using instead thereof a new form of vertical bar H, the
upper end of which is made with an inverted spring leg L. Each end of the
faller 1 has a groove cut or formed therein opposite to the spring leg, as is usual,
and as each faller I arrives at the end of the top saddle E, it is forced down by the
usual cam G and compresses the spring leg L and it is guided accurately down
thereby to the bottom saddle, but as soon as the top of the said faller has got to
the underside of the upper saddle E the spring leg L is released and it immediately
springs forward, forcing the faller on to the lower saddle into a position which
prevents rebounding as is common with this class of machine nor can it become
locked, but is at once received into the bottom screws.
With regard to the right hand side of drawing Fig. 2, the vertical bar H having
a spring leg L is employed for the purpose of guiding the lower fallers I) to the
upper saddle E, the spring leg L forcing the fallers D into a proper position to
be taken hold of by the upper screw B.
By means of our invention the wear and tear of the fallers, and bed and screws
is considerably lessened, in addition to which there is less liability of the fallers
rebounding or becoming locked, which is a frequent occurrence in the present
machines, whilst these several advantages permit the machine to be run at an
increased speed, thus the said machines will do more work in a given time than
those at present in uso.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is: —
In gill boxes for preparing fibrous materials, the use therein of a vertical bar
such as II provided at one end with an inverted spring leg such as L employed
substantially in the manner shewn, and for the purposes described.
