Improvements in Gill Boxes for Preparing Wool and other Fibre.

This invention relates to gill boxes employed in preparing wool and other fibres.
It is well known that the greatest wear and tear in this class of machine occurs
with the fallers and parts connected therewith.
Our improvements consist in the employment of a new form of mechanism for
lessening the wear and tear of the fallers whilst our new apparatus permits the
machine to be run at a greatly accelerated speed.
In carrying out our invention, we place under the fallers, one or more spring
feet which receive each faller as they are pushed down by the cams, the weight
of a faller causing such spring feet to descend and convey each succeeding faller.
softly on to the bed upon which it rests. These spring feet are preferably con-
nected to the upper end of a pair of bars, placed diagonally, and centred in the
middle after the manner of shears or scissors, but the bottom end of the said
diagonal bars are bent in the form of springs so that when the feet above have been
depressed, the springs will force the feet up again (when it has parted with its
faller) so as to permit the feet to receive the next faller whereby the said fallers
are received in quick succession and conveyed softly on to the bed.
When ordinary forms of gill boxes have been in operation for some time, without
our improvements, that portion of the bed where the fallers drop, becomes worn
and hollowed out, on the other hand the ends of the fallers become worn which is
a hindrance to the proper working of the machines, as great strain is placed upon
the screws to force the fallers from the worn bed. To prevent the strain upon the
screws just mentioned, we cause the spring feet to carry the faller backward into
the machine some short distance, and this is effected automatically by means of
a lever, one end of which is in connection with the diagonal spring feet, whilst
the opposite end is operated by a cam or tappet. By this arrangement the fallers
have a straight drop and then are drawn bodily forward into the machine and
placed in a proper position to be received by the screws.
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
getting locked which is a frequent occurrence in the present machines, whilst

spring feet carry the fallers gently down on to their bed, the loud noise occasioned
by their dropping from the top screw to the bottom screw is considerably lessened.

page_text: Improvements in Gill Boxes for Preparing Wool and other Fibre.
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:-
This invention relates to gill boxes employed in preparing wool and other fibres.
It is well known that the greatest wear and tear in this class of machine occurs
with the fallers and parts connected therewith.
Our improvements consist in the employment of a new form of mechanism for
lessening the wear and tear of the fallers whilst our new apparatus permits the
machine to be run at a greatly accelerated speed, especially is this the case with
heavy gill boxes.
In carrying out our invention, we place under the fallers, one or more spring
feet which receive each faller as it is pushed down by the cams, the weight of a
faller partially causing such spring feet to descend, being assisted by well known
cams which convey each succeeding faller softly on to the bed upon which it rests.
These spring feet are preferably connected to the upper end of a pair of bars,
placed diagonally, and centred in the middle after the manner of shears or scissors,
but the outer end of the said diagonal bars are bent in the form of springs so that
when the feet above have been depressed, the springs will force the feet up again
(when it has parted with its faller) so as to permit the feet to receive the next faller
whereby the said fallers are received in quick succession and conveyed softly on
to the bed.
In order that our invention may be clearly understood, we will make reference
to the accompanying sheets of drawings which illustrate sufficient parts of a gill
box as to show our improvements.
Fig. 1 is a front elevation and Fig. 2 cross section of a gill box taken on line x, x
in Fig. 1. Fig. 3 is an enlarged view of Fig. 1. Fig. 4 is a cross section
through y, y, in Fig. 3.
A is the framework of the machine, B the upper screw for working the fallers
forward, the lower screw employed to bring the fallers I) 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 con-
struction and form no part of our invention.
In order to prevent the fallers dropping from the upper saddle to the lower
saddle as is customary, we, according to our invention, employ a pair of diagonal
spring bars G each outer end of which is provided with a foot or projection H
the opposite end of these diagonal bars are made with a spring I of any suitable
shape secured under the framework A by nut a.
These
Fig. 5 is an end view of one of the diagonal spring bars or levers G.
diagonal spring bars are supported or connected about the middle thereof, in a box
or casing J, see Fig. 6 the bottom of which may be attached to a lever K controlled
by cam or tappet L at the back of the machine or otherwise. This cam is so
timed that as each upper faller D arrives at the outward end of the upper saddle E
that the diagonal arms G with the feet H are just in a position to receive the faller
as it leaves the saddle, see Fig. 4 the weight of which also partly overcomes the
elasticity of the spring I whereby each faller is lowered or carried from the top
saddle to the lower saddle and not allowed to drop as is customary, whereby the

page_text: wear and tear of the extreme ends of the fallers, together with the saddles upon
which they have dropped, is now entirely avoided and the noise occasioned by
their dropping from the top saddle to the bottom saddle is considerably lessened.
Instead of the diagonal spring bars G passing through a box J at the part
where they cross each other as shewn in Figs. 1 and 3, the said spring bars G may
be connected as shewn in Figs. 7 and 8, the latter being a section through line s, s,
of Fig. 7, where it will be seen that one spring bar G is connected by link M
which has its lower part connected to hinged joint N by stud 0 to operating
lever K, whilst the other spring bar is connected by link P to a pin R projecting
from the upper part of hinged joint N.
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
getting locked which is a frequent occurence in the present machines, whilst these
several advantages permit the machine to be run at an increased speed, thus the
said machine will do more work than those at present in use.
As the spring feet carry the faller gently down on to their bed, the loud noise
occasioned by their dropping from the top screw to the bottomu screw is consider-
ably lessened.
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:-
Firstly. In gill boxes, the employment of diagonal spring bars G for receiving
the fallers and carrying them from the upper saddle to the lower saddle, in the
manner substantially as herein shewn and described.
Secondly. In gill boxes the employment of diagonal spring bars G. provided
with feet H for receiving the fallers, such said diagonal spring bars being operated
and regulated in their motion by a cam or tappet L connected with lever K all
arranged and operated substantially as shewn and described.
