Improvements in Change Box Mechanism of Looms for Weaving.
We, RICHARD LONGDEN HATTERSLEY, of North Brook Works, Keighley, in the
County of York, Machine Maker, and SIMEON JACKSON, of the same address,
Manager, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to make a greater reduction than hitherto in
the length of the pattern surfaces used in controlling the action of revolving shuttle
boxes. In our invention we make use of the motion as claimed in Specification
No. 18,267 of 1890, and have made an addition to same as hereafter explained.
--
The invention numbered 18,267 of 1890 consists of two cylinders with a sett
of levers and catch for each. Over each of these two cylinders passes a chain
of indicating cards which indicate upon their respective setts of levers. Each sett
of levers is composed of one lever for indicating to the third cylinder, hereafter
referred to, and two ordinary feelers which transmit the motion by means of
projecting pins to the ordinary intermediate levers of the box motion. The two
cylinders are operated in their forward direction by two catches, one for each,
and these, the latter, are under the control of the third cylinder, so that each
catch can be brought into or out of contact with its respective cylinder at any
predetermined moment and thus either of the two cylinders becomes operative or
at rest as indicated by the pattern surface of the third cylinder.
We will now describe the addition made by us to this motion :-
With regard to the two setts of levers both setts are of like construction so we
will describe our arrangement of one sett. To each of the two ordinary feelers we
attach a block in such a manner that it can be slided horizontally in a slide
formed in the said feeler. The projecting pin or pins are attached to this sliding
block and are arranged in such a manner that when the blocks are at their
forward position the pin attached to the sliding block of the first feeler indicates
upon the intermediate lever which governs the forward motion of the box, and
the pin attached to the sliding block of the second feeler indicates upon the
intermediate lever which governs the backward motion of the box and when
the blocks are at their back position the projecting pins act reversely namely the
pin for the first feeler indicates on the intermediate lever for the backward motion
of the box and the pin for the second feeler indicates on that for the forward
motion of the box. These two blocks are coupled together and their movement
controlled by the third cylinder.
The catches are of like construction for both cylinders. The following is a descrip-
tion for one cylinder:We adapt two catches to one cylinder they are mounted
loosely on studs and connected together in such a manner that when one catch is in
contact the other is thrown out of contact with the cylinder and when one catch is in
connection with the cylinder the latter is turned forward and when the other is
in connection it is turned backwards. The catches are controlled from the third
cylinder from which they receive three indications, namely:-one to put the catch

page_text: imparting forward motion into contact with the cylinder, one to put the catch
imparting backward motion into contact, and one to put both catches out of
contact with the cylinder.
'
Thus we impart three indications from the third cylinder to each of the two
cylinders and to each of the two setts of feelers, that is, one for the forward
motion of the cylinder with the projecting pins in their normal position, one
for the backward motion of the cylinder and reversing the projecting pins, and
one for throwing both catches out of gear, and thus not operating the cylinder
with the projecting pins at their central or non-operative position.
The blocks are designed so that when they are at their central position the
lever for indicating to the third cylinder is rendered inoperative and they are
arranged to work in unison with the catches for each respective cylinder.
From this it will be seen that two pattern surfaces can be utilised in the
manner shown in Specification numbered 18,267 of 1890, and also any part of
such pattern surfaces can be reversed at any predetermined moment, and thus a
great saving in the length of same is effected.

Improvements in Change Box Mechanism of Looms for Weaving.
We, RICHARD LONGDEN HATTERSLEY, of Nerth Brook Works, Keighley, in the
County of York, Machine Maker, and SIMEON JACKSON, of the same address,
Manager, 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 is to make a greater reduction than hitherto in
the length of the pattern surfaces used in controlling the action of revolving shuttle
boxes. In our invention we make use of the motion as claimed in Specification
No. 18,267 of 1890, and have made an addition to same as hereafter explained..
The invention numbered 18,267 of 1890 consists of two cylinders with a set
of levers and catch for each. Over each of these two cylinders passes a chain
of indicating cards which indicate upon their respective sets of levers. Each set
of levers composed of one lever for indicating to the third cylinder, hereafter
referred to, and two ordinary feelers which transmit the motion by means of
projecting pins to the ordinary intermediate levers of the box motion. The two
cylinders are operated in their forward direction by two catches, one for each,
and these, the latter, are under the control of the third cylinder, so that each
catch can be brought into or out of contact with its respective cylinder at any
predetermined moment and thus either of the two cylinders becomes operative and
at rest as indicated by the pattern surface of the third cylinder.
We will now describe the addition made by us to this motion:--With
regard to the two sets of levers both sets are of like construction, so
we will
describe our arrangement of one set. To each of the two ordinary feelers we
attach a block in such a manner that it can be slided horizontally in a slide
formed in the said feeler. The projecting pin or pins are attached to this sliding
block and are arranged in such a manner that when the blocks are at their
forward position the pin attached to the sliding block of the first feeler indicates
upon the intermediate lever which governs the forward motion of the box, and

page_text: the pin attached to the sliding block of the second feeler indicates upon the
intermediate lever which governs the backward motion of the box and when
the blocks are at their back position the projecting pins act reversely namely the
pin for the first feeler indicates on the intermediate lever for the backward motion
of the box and the pin for the second feeler indicates on that for the forward
motion of the box. These two blocks are coupled together and their movement
controlled by the third cylinder.
The catches are of like construction for both cylinders. The following is a descrip-
tion for one cylinder:We adapt two catches to one cylinder, they are mounted
loosely on studs and connected together in such a manner that when one catch is in
contact the other is thrown out of contact with the cylinder and when one catch is in
connection with the cylinder the latter is turned forward and when the other is
in connection it is turned backwards. The catches are controlled from the third
cylinder from which they receive three indications, namely, one to put the catch
imparting forward motion into contact with the cylinder, one to put the catch
imparting backward motion into contact, and one to put both catches out of
contact with the cylinder.
Thus we impart three indications from the third cylinder to each of the two
cylinders and to each of the two sets of feelers, that is, one for the forward
motion of the cylinder with the projecting pins in their normal position, one
for the backward motion of the cylinder and reversing the projecting pins, and
one for throwing both catches out of gear, and thus not operating the cylinder
with the projecting pins at their central or non-operative position.
The blocks are designed so that when they are at their central position the
lever for indicating to the third cylinder is rendered inoperative and they are
arranged to work in unison with the catches for each respective cylinder.
From this it will be seen that two pattern surfaces can be utilised in the
manner shown in Specification numbered 18,267 of 1890, and also any part of
such pattern surfaces can be reversed at any predetermined moment, and thus a
great saving in the length of same is effected.
In order to make clear our invention we append hereto a sheet of drawings
marked with figures of reference in which like figures denote like parts.
Fig. I is an elevation of our motion. Figs. II & III are plan views of same
and Fig. IV a part elevation.
In this our improvement we make use of the ordinary box lever 1, catches 2 & 3,
tappit 4, eccentric 5, rods 6 & 6 for transmitting the movement to the revolving
box from our improved arrangement of indicating levers. We also make use of
the two cylinders 7 & 8 over which pass two chains of indicating cards 9 & 10,
the third cylinder 11, levers 12 & 13 and catches 14 & 15 for operating this
third cylinder all as shown and claimed in Specification numbered 18267 of 1890.
Our improvement consists of two sets of indicating levers 16, 17, 18, 19 mounted
loosely on the stud 20 in each of which there is a slot 21, 22, 23, 24 prepared to
receive a sliding block 25, 26, 27, 28. The set of blocks 25 & 26 is connected by
rod 29 to lever 30 and the latter is rigidly mounted on the sleeve 31 of the
lever 32, hereafter referred to. The set of blocks 27 & 28 is connected by
rod 33 to lever 34. The two levers 30 & 34 are connected by rods 35 & 36 to the
two levers 37 & 8 and the latter are operated upon by the pattern surface 39
passing over the before mentioned cylinder 11.
The catches 40 & 41 which operate the cylinder 7 are mounted loosely on the
studs 42 & 43 and their arms 44 & 45 are connected together as shown in Fig. IV
by fod 46, spring 47. A spring 48 and stand 49 are applied to hold the catches
in the position indicated by the pattern surface 39 of the third cylinder 11 being
brought into connection with same by rod 50 which is connected to the before
mentioned lever 32. The two catches 51 & 52 which operate the cylinder 8 are
likewise loosely mounted on the studs 42 & 43 and connected together same as the
catches 40 & 41 and they are brought into connection with the before mentioned
lever 34 by rod 53.

page_text: As shown in Figs. I & III the pattern surface 39 consists of a set of steel
cards carrying two rows of pegs one for lever 37 and the other for lever 38;
three movements are imparted from same by means of a peg, a half peg, and a
blank or no peg.
The third cylinder is operated when desired from either of the two cylinders 7 & 8
as explained in Specification numbered 18267 of 1890, and thus if on the operation
of this cylinder a peg is presented to the lever 37 the cylinder 7 is turned back-
wards and the blocks 25 & 26 are at their back or reversed position, if a half
peg is presented the cylinder 7 is not turned, the catches 40 & 41 being held
clear of same and the blocks are at their midway position and when in this
position the pins attached to same are clear of the levers 54 & 55 and thus no
indication is imparted, if no peg is presented then the cylinder 7 is turned
forward and the blocks are at their forward position.
Exactly the same effects on the cylinder 8 and blocks 27 & 28 are obtained from
the indication imparted by the pattern surface 39 to the lever 38.
To the block 26 we attach a piece 56 so adjusted that when the blocks 25 & 26
are at their midway position the nose 57 on lever 13 rests on same and by this
Also to the
means the latter receives no indication from the pattern surface 9.
block 27 a piece 58 is attached which meets the nose 59 on lever 12 with a
like result.
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:-
-
The application of two sets of sliding blocks and two sets of cylinder catches
to the mechanism claimed in Specification of Letters Patent number 18267 of
1890 for the purpose of reversing the pattern when required.
