Year: 1873

page_text: ETTERS PATENT to Joseph Naylor, of the Firm of Watson and
Naylor, of Kidderminster, in the County of Worcester, Carpet
Manufacturers, and Joseph Jagger, of the said Kidderminster, and
in the employment of the said Firm, Overlooker, for the Invention
of "IMPROVEMENTS IN LOOMS FOR WEAVING KIDDERMINSTER OR INGRAIN
CARPETS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE IN THE WEAVING OF
OTHER FABRICS.”
Sealed the 1st May 1874, and dated the 19th December 1873.
PROVISIONAL SPECIFICATION left by the said Joseph Naylor and
Joseph Jagger at the Office of the Commissioners of Patents, with
their Petition, on the 19th December 1873.
We, JOSEPH NAYLOR, of the Firm of Watson and Naylor, of
Kidderminster, in the County of Worcester, Carpet Manufacturers, and
JOSEPH JAGGER, of the said Kidderminster, and in the employment of
the said Firm, Overlooker, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING KIDDERMINSTER OR

page_text: NURAIN CARPETS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE IN THE WEAVING OF
OTHER FABRICS," to be as follows:-
The object of the Invention is to facilitate the effecting changes in the
selection of the shuttles for changes of weft.
In carrying out our improvements the series of shuttle chambers at
each side of the loom are supported to slide in guides, or are otherwise
carried by and move with the batten; but this arrangement separately
considered forms no part of our Invention.
Each series of shuttle chambers is connected to so as to be operated
by a rocking lever with balance weight, and the movement thereto is
obtained by a cam or tappet the course of which is varied to correspond
with the traverse of the chambers. This cam or tappt acts on a truck
or bowl carried by a lever and connecting means.
To the cam or tappet or the axis thereof is applied a star wheel, the
radial notches in which are capable of being taken into by studs from
one or other of a pair of wheels which are caused to revolve so that
when one of them is geared with the star wheel that wheel and the cam
or tappet wheel connected thereto will be caused to move in onc
direction, or when the other stud wheel is geared with the star wheel
the star wheel and the cam or tappet will be caused to move in the
opposite direction. The sliding of these stud wheels, so that one or the
other of them may be in gear with the star wheel, or so that both stud
wheels may be free of the star wheel, is effected by a rocking lever
forked at both ends to embrace necks in the bosses of these stud
wheels.
The forked lever is actuated by another lever having a recess and
inclines applied to it, acted upon by a spring bowl with a tendency to
keep the forked lever in a central position, whilst its movement in either
direction, so as to bring one or the other of the stud wheels into
operation, is effected by the movements of the jacquard acting on one
or the other end of a T lever with spring knuckle joints capable of
acting rigidly for working purposes or of yielding in the event of
extra strain through the derangement of any of the parts.
The forked lever is held in position after selection by the V end of a
sliding stud acting in one or the other of three V grooves, and this stud

page_text: is released from them by tappet and lever. The star wheel and cam or
tappet attached thereto are held after each change by spring, bowl, or
such like means acting in one or other of a series of corresponding
recesses. Corresponding movements are applied at each side of the
Joom
Variations may be made in the details indicated, and the series of
shuttle chambers in place of being applied to the batten may be
separate therefrom.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Naylor and Joseph Jagger in the Great
Seal Patent Office on the 18th June 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
NAYLOR, of the Firm of Watson and Naylor, of Kidderminster, in the
County of Worcester, Carpet Manufacturers, and JOSEPH JAGGER, of
the said Kidderminster, and in the employment of the said Firm,
Overlooker, send greeting.

and assigns, should at any time agree with and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN LOOMS FOR
WEAVING KIDDERMINSTER OR INGRAIN CARPETS, WHICH IMPROVEMENTS ARE
ALSO APPLICABLE IN THE WEAVING OF OTHER FABRICS," upon the condition

page_text: our executors or administrators, by an instrument in writing under
our or their hands and seals, or under the hands and seals of one of us
or them, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed,. and
cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said Joseph Naylor and Joseph Jagger,
do hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say:
The object of the Invention is to facilitate the effecting changes in the
selection of the shuttles for changes of weft.
In carrying out our improvements the series of shuttle chambers at
each side of the loom are supported to slide in guides, or are otherwise
carried by and move with the batten; but this arrangement separately
considered forms no part of our Invention.
Each series of shuttle chambers is connected to so as to be operated
by a rocking lever with balance weight, and the movement thereto is
obtained by a cam or tappet, the course of which is varied to correspond
with the traverse of the chambers. This cam or tappet acts on a truck
or bowl carried by a lever and connecting means.
To the cam or tappet or the axis thereof is applied a star wheel, the
radial notches in which are capable of being taken into by studs from
one or other of a pair of wheels which are caused to revolve so that
when one of them is geared with the star wheel that wheel and the cam
or tappet wheel connected thereto will be caused to move in one
direction, or when the other stud wheel is geared with the star wheel
the star wheel and the cam or tappet will be caused to move in the
opposite direction. The sliding of these stud wheels, so that one or the
other of them may be in gear with the star wheel, or so that both stud
wheels may be free of the star wheel, is effected by a rocking lever
forked at both ends to embrace necks in the bosses of these stud
wheels.

slide in guides, or is otherwise carried by and so as to move with the
batten, so that any of these series of shuttle chambers c may when
desired be capable of being brought into a line with the race of the
batten for the passage of shuttle through an open shed in the warp.
To facilitate these movements the frame c¹ is connected by pin joint d¹
to one end of a connecting rod d which is capable of adjustment as to
length at d², and at its other end d³ is connected to one end of the
rocking balance lever e which is supported to rock on the fixed stud e¹,
and at its other end is provided with a balance weight e capable of
adjustment. This rocking balance lever e is operated to bring either of
the shuttle chambers c into a line with the race of the batten by means
of the cam course f¹ applied so as to project from one surface of the
wheel by that surface f¹ acting upon a truck or bowl g¹ carried by the
'lever g, which at one end is supported to rock on a fixed stud 9² and at
the other end is by pin joint g³ connected to one end of the connecting
rod 9, the other end of which is by pin joint g³ connected to the lever e.
The cam course f¹ is formed so that in its action on the bowl g¹ and
parts connected therewith it may bring any one of the chambers c in a
line with the race of the batten. For this purpose the wheelf is capable
of partial rotation in either direction according to the selection for the
time desired; and to effect these [motions in the required order the
wheelf with its cam course f¹ is affixed to a short shaft f² which is
supported with capability of freely revolving in suitable bearings.

Upon the crank shaft 6 is affixed a toothed wheel h, the teeth of
which take into the teeth of another tooth wheel i, and this wheel i is
applied to a shaft which is supported freely to revolve in suitable
bearings; and has applied to it the tooth wheel j, the teeth of which are
at the same time taken into by the teeth of the toothed wheel k and by
the teeth of the stud wheel 1, the teeth of which are also taken into by
'the teeth of the wheel m. The tooth wheel is affixed on the short
shaft which is supported to turn freely in suitable bearings; and
on the shaft m¹, and is
the tooth wheel m is in like manner affixed
supported to revolve in suitable bearings. Upon the shafts k¹ and m¹
are applied wheels or disks k² and m³, each of which is capable of sliding
endwise on its shaft, whilst it is keyed to revolve with it. These wheels
² and m² are each provided with studs ³, m³, projecting from their
respective surfaces; and the object of them is, that when either wheel k²

page_text: formed double; one part p or which is also formed with the double
inclines p³, p³, which are acted upon by elastic force applied to the
bowl p with a tendency to keep the lever p in a position for holding the
lever o in that position which will keep the wheels k² and m² free of the
wheel f.
The elastic force to the bowl p is obtained by that bowl being
carried by the forked end of the rod p" which is supported to have free
endway motion in the stationary guides a², whilst it is acted upon for
the desired elastic pressure by the spiral spring p' with capability of
adjustment. The other end p³ of the lever p is by the connecting rod q
connected to the T lever r, the arms of which are formed with spring
knuckle joints 7³, as shown, and are connected by links 8, 8, to
levers & operated by the Jacquard or pattern surface for the selection
desired.
The lever o is held in position, after each selection by the pattern
surface, by the pointed end of the pin u entering one or the other
of the V grooves formed in the boss m² of the wheel m². This pin u is
affixed by pin joint to one end of the lever which is supported
to turn on the fixed stud v¹, whilst at its other end it carries a
truck or bowl v² which rests on the under side of the cam v3 which is
affixed on the shaft ¹ to rotate with it and thereby release the pin u
from the grooves m* at the time of rocking of the lever o. The upper end
of the pin u is guided by moving in a hole formed for it in a bracket
piece a³; and that end of the lever vis borne upon by the spring w to
keep the bowl at the other end of it bearing against the surface of the
cam or tappet.
