Improvements in Looms for Weaving Carpets and other Fabrics.
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:-
This invention consists of an arrangement of the driving, that is, the trans-
mission of power to the different motory parts, of this loom, which is adapted to
weave Chenille or Axminster Carpets and Rugs.
Also the manner of giving motion to the carrier, which travels across the loom,
and lays the chenille on the face of the cloth.
In order to make clear our invention, we will briefly explain the ordinary
manner of working for this class of loom. The ground of the carpet may be of
any pattern suitable, and across the face of the piece is laid, at intervals, a length
of the chenille weft, which is bound into the cloth by a binding warp. It will
be seen that the treading, picking, and beat-up, for the ground, must be at rest,
whilst the motion for laying and binding the chenille is in motion. In the
present arrangement, we have allowed 4 parts of the round for the ground to 8
parts for the rest, but any other proportion may be adopted.
Our method of driving the loom is as follows:-The motion is imparted, in any
ordinary manner, to the tappet-shaft of the loom, and on this shaft is mounted a
wheel, which gears intermittently with a stud-wheel, the diameter of which is
one-third of that of its driver. To this stud-wheel is attached another wheel,
mounted on the same stud, which gives motion to a wheel mounted on the crank-
shaft, the latter wheel having one-quarter the number of teeth of the former.
For the picking motion, we mount the two tappets on an extra shaft, which
derives its motion from the same wheel as the crank-shaft, and is geared so that it
makes half the number of revolutions of the said crank-shaft.
The treading motion for the healds, belonging to the ground, is worked by
tappets mounted on the before-mentioned tappet-shaft. These are designed twelve
to the round, and are so arranged that when the tappets have made the four
movements necessary, the healds remain in a midway position for the remaining
eight parts of the revolution.
As the wheel mounted on the tappet-shaft has only teeth on one-third of its
periphery, that is, the same number of teeth as the wheel with which it gears, it
will be seen, that whilst the tappet-shaft is making one-third of a revolution, the
crank-shaft makes four revolutions, and the picking-shaft two revolutions, also
that during the remaining two-thirds of its revolution, the beat-up and picking
motions are at rest. From the description of the treading tappets, it is clear that
the healds are held stationary, in a midway position, during the said two-thirds
of a revolution.
By these means, time is allowed for the chenille motion to lay the chenille in:
the position required.
Our method of giving motion to the chenille camion is so fall

Improvements in Looms for Weaving Carpets and other Fabrics.
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 and in what manner the
. same is to be performed, to be particularly described and ascertained in and by.
the following statement:-
This invention consists in an arrangement of the driving, that is, the trans-
mission of power to the different motory parts of this loom, which is adapted to
weave Chenille or Axminster carpets and rugs.
Also the manner of giving motion to the carrier, which travels across the loom,
and lays the chenille on the face of the cloth.
In order to make clear our invention, we will briefly explain, the ordinary
manner of working this class of loom. The ground of the carpet may be of
any pattern suitable, and across the face of the piece is laid, at intervals, a length
of the chenille weft, which is bound into the cloth by a binding warp. It will
be seen that the treading, picking, and beat-up, for the ground, must be at rest,
whilst the motion for laying and binding the chenille is in motion. In the
present arrangement we have allowed four parts of the round for the ground to
eight parts for the rest, but any other proportion may be adopted.
Our method of driving the loom is as follows:-The motion is imparted, in any
ordinary manner, to the tappet shaft of the loom, and on this shaft is mounted a
wheel, which gears intermittently with a stud-wheel, the diameter of which is
one-third of that of its driver. To this stud wheel is attached another wheel,
mounted on the same stud, which gives motion to a wheel mounted on the crank-
shaft, the latter wheel having one-quarter the number of teeth of the former.
For the picking motion, we mount the two tappets on an extra shaft, which
derives its motion from the same wheel as the crank shaft, and is geared so that it
makes half the number of revolutions of the said crank-shaft.
The treading motion for the healds, belonging to the ground, is worked by
tappets mounted on the before-mentioned tappet-shaft. These are designed twelve
to the round, and are so arranged that when the tappets have made the four
movements necessary, the healds remain in a midway position for the remaining
eight parts of the revolution.
As the wheel mounted on the tappet shaft has only teeth on one-third of its
periphery, that is, the same number of teeth as the wheel with which it gears, it
will be seen that whilst the tappet-shaft is making one-third of a revolution, the
crank-shaft makes four revolutions, and the picking shaft two revolutions, also
that during the remaining two-thirds of its revolution, the beat-up and picking
motions are at rest, From the description of the treading tappets, it is clear that

page_text: the healds are held stationary, in a midway position, during the said two-thirds
of a revolution.
By these means, time is allowed for the chenille motion to lay the chenille in
the position required.
Our method of giving motion to the chenille-carrier is as follows:-
The carrier is connected by a cord to a pulley to which is attached a pinion or
wheel, and the latter is operated by a segment wheel, working on a fixed centre.
The segment wheel is connected by rod and excentric to a stud, on which is
mounted a toothed wheel, and the latter is revolved intermittently by a wheel
working with the tappet-shaft. Thus the chenille is laid at the time and in the
position required.
In order to explain more clearly our invention, we append hereto two sheets of
drawings marked with letters and figures of reference, in which like letters and
figures denote like parts.
Fig. I shows an end elevation of the driving motion of the loom; Fig. II and
Fig. III end and plan views of the Chenille Motion.
In Fig. I. is shown our arrangement for the drving of the loom. The motion is
transferred from the shaft A, which may receive its motion in any well-known
manner, to the shaft A', by means of the wheels A2, A3, A4, A5. It will be seen
that, as the diameter of the wheel A3 is one-third of that of the wheel A³, and the
wheel A5 one-quarter of that of the wheel A'; the shaft A makes four revolutions
whilst the shaft A makes one-third of a revolution. Also that as the wheel A has
teeth only on one-third of its periphery, the shaft A¹ is at rest for the remaining
two-thirds of the revolution of the shaft A.
As shown in Fig. 1, the wheel A is in connection with the wheel A, and the
latter is mounted rigidly on the same shaft A7 as the picking tappets A8. The
diameter of the wheel A6 is one-half of that of the wheel A and thus the shaft A
will make two revolutions, whilst the shaft A is making one-third of a revolution,
and will be at rest for the remaining two-thirds of its revolution.
It will be clear from the foregoing description, that whilst the shaft A is making
one revolution, the shaft A¹ makes four, and is at rest equal to eight revolutions,
also that the tappet shaft A7 is revolved on the same ratio.
In the foregoing description, we show four parts of the revolution of the shaft A
for imparting motion and eight parts for rest; but we can arrange, if required,
any other proportion in like manner.
We mount on the

is in gear with a wheel B', which is connected by crank B and
segment wheel B4, the latter working on the fixed centre 135.
wheel B imparts motion to a grooved pulley B6, by means of the wheel B, and
we connect the carrier 18 to the before-mentioned pulley by cord B³. The method
of connecting the carrier, which traverses freely across the loom on shafts 110 & B¹¹,
is shown in Figs. 2 & 3, the cord being guided by the three pulleys B1, B3, B4
and bowls B15 & B16.
It will be seen from Figs. 2 & 3 that the carrier B travels across the loom on
each revolution of the shaft A, and thus lays the chenille weft B, which passes
freely through the said carrier 18, on the face of the piece 118 The manner of
connecting the chenille weft by a binding warp to the piece is well understood and
not included in our present invention. The operations of the carrier 138 may be
varied as required.
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:-

class of loom, as shown and described.
