page_text: LETTERS PATENT to Arthur Edward Walker, Woollen Manufacturer, Wright
Haigh, Loom Tuner, and Joseph Brook, Blacksmith, all of Lindley, near
Huddersfield, in the County of York, for the Invention of "IMPROVEMENTS
IN LOOMS FOR WEAVING."
Sealed the 3rd February 1880, and dated the 9th August 1879.
PROVISIONAL SPECIFICATION left by the said Arthur Edward Walker,
Wright Haigh, and Joseph Brook at the Office of the Commissioners of
Patents on the 9th August 1879
ARTHUR EDWARD WALKER, Woollen Manufacturer, WRIGHT HAIGH, Loom
Tuner, and JOSEPH BROOK, Blacksmith, all of Lindley, near Huddersfield, in the
County of York. "IMPROVEMENTS IN LOOMS FOR WEAVING."
Heretofore in the weaving of looped fabrics from which by cutting the loops
plush and such like pile fabrics are produced ordinary power looms were not
generally available, the hand loom or a loom having a wiring motion, such as the
carpet loom, being used.
Now the object of this our Invention is by the application to an ordinary power
loom of mechanism, hereinafter described, to render such power loom applicable to
and available in the weaving of fabrics aforesaid.
In connection and combination with an ordinary power loom we employ a
tappet by preference on the first driving shaft, the tappet being free to slide along its
shaft, and such tappet is by levers under the control of link tappets, lag and pegs,
or such like appliance, so that when the desired number of picks have been made
the tappet will operate a lever and rods connected with the stop handle or other
stop motion of the loom, another lever and links and connecting rods put in
operation a brake, so that the motion of the loom is arrested automatically at the
time and when the shed is prepared for the introduction of the wire by hand, and
Prins 1077

be employed in connection with levers for acting on the stopping mechanism of
the loom at predetermined intervals for introduction of the wires for purpose
aforesaid.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Arthur Edward Walker, Wright Haigh, and Joseph Brooke in the
Great Seal Patent Office on the 9th February 1880.

Tuner, and JOSEPH BROOK, Blacksmith, all of Lindley, near Huddersfield, in the
County of York. "IMPROVEMENTS IN LOOMS FOR WEAVING."
"
Heretofore in weaving of looped fabrics from which by cutting the loops "plush
and such like pile fabrics are produced ordinary power looms were not generally
available, the "hand" loom or a loom having a "wiring" motion, such as the carpet
loom, being used.
Now the object of this our Invention is by the application to an ordinary power
loom of mechanism, hereinafter described, to render such power loom applicable to
and available in the weaving of fabrics aforesaid.
In connection and combination with an ordinary power loom we employ a tappet,
by preference on the first driving shaft, the tappet being free to slide along its
shaft, and such tappet is by levers under the control of link tappets, lag and pegs,
or such like appliance, so that when the desired number of picks have been made
the tappet will operate a lever and rods connected with the stop handle or other
stop motion of loom; another lever and links and connecting rods put in operation
a brake, so that the motion of the loom is arrested automatically at the time and
when the "shed" is prepared for the introduction of the "wire" by hand, and this
is repeated for the introduction of each succeeding wire.
"
Or the " "jack may be employed in connection with levers for acting on the
stopping mechanism and the brake of the loom at predetermined intervals for the
introduction of the wires for the purpose aforesaid.
Such being the nature and object of this our said Invention, in order that the
same may be fully understood, we will now proceed to describe by the aid of
the bereunto annexed five Sheets of Drawings our improvements as applied to a
change shuttle box loom, and we have marked the parts of the several views or
figures with numbers of reference, a like number indicating the like part in the
several views.

page_text: At 1 is a fly cage, having link tappets 2 (lag and pegs or other like appliances),
the link tappets being so arranged as that whilst the desired number of picks or
shots are being made the tappet 2 will raise the end arm of the bell crank lever 4
on its fulcrum 5, and its other arm 4 moves the connecting rod 7, and lever 8
move the latter on its fulcrum 9, and by the clip 10 hold the tappet 11 clear of the
end of lever 12 (see Fig. 2), the latter by rod 13 and connection 14 acting on the
stop handle 15 of the loom. So soon however as a blank 3 in the chain of tappets
is brought under the lever 4 the latter descends to position shewn by dotted lines
and the connections 7, 8, are moved by gravitation of lever 4 and by the action of
the spring 16, so as to bring the tappet 11 (by sliding it along its shaft 6) in line
with the lever 12; the swell 17 is then acted upon by the tappet 11, and by means
of the connecting rod 13 and intervening part 14 the stop handle is forced out of
its retaining notch, so "knocking off" and stopping the loom by the transfer of the
strap from the fast to the loose pulley as is well understood.
Meanwhile, a corresponding chain of tappets to those referred to and a like
lever 4 and parts 7, 8, 9, 10, to the left hand will in precisely the same manner act,
holding the tappet 12º (see Fig. 3) on its sliding boss or shaft 6 clear of the
bowl 20 of the lever 21, until a blank 3 in the chain of tappets comes round,
whereon the lever 4 falls and the connections 7, 8, 9, 10 admit of the spring 16
and gravitation of the lever 4 sliding the tappet 12ª into position, the tappet 12ª
acting on the bowl 20, and depressing the lever 21 (see Fig. 4) on its fulcrum 22,
the lowered end 23 of the lever 21 by connecting rod 24, lever 25, and rods 26 (see
Fig. 5), raising the end of the lever 27 on its fulcrum 28, and by depressing the
end 29 applying the strap brake 30 to the periphery of the brake wheel 31, such
application of brake following immediately on the "knocking off" the stop handle
as above described. So soon as the attendant inserts a wire (as in the hand wire
pile loop weaving) and the loom is again started, and a lifting tappet 2 again acts
on the arm 4 of the bell crank lever, the connections 7, 8, 9 overcome the power
of the spring 16, and the eccentrics 11 and 12ª are by the connections 7, 8, 9, 10,
caused to slide along their axis or boss 6, clear of the levers 12 and 21, until the
required number of picks have again been made, whereon another blank 3 in the
tappet chain occurs, which is followed by the lowering of arm 4 of bell crank lever,
and springs 16 operating the levers and connections so as to bring the tappets 11
and 12ª in position for acting on the levers 12, 21, and 27, so as to stop the loom
and apply the brake as before.

It is evident that the mechanism, which we have herein before described as
applied to a change shuttle box loom having link tappets, may be readily applied
to looms in which "jacks are used, and in these cases the crank levers 4 and 4ª
may be dispensed with and the lever 8 may be acted upon by the jacks and rods 7,
the other parts of the loom being arranged and operated upon in the manner
herein before described as illustrated by Figures 6, 7, 8, Sheet 5, in which 2 is an
ordinary jack lever operating through its usual motions the rocking lever 3 on its
fulcrum 4. To the other end 5 of the lever 3 is attached an adjustable sliding
plate 6, having an oblique or cam slot therein and through which slot and through
the ends of the rods 7, 7, a stud is passed that as the plate 6 is by the action of the
levers 2 and 3 raised or lowered in its guide, the ends of the rods 7, 7, will be
operated so as to push and pull the connections 8, 9, 10, for purpose described.
Having thus fully described the nature and particulars of this our said Inven-
tion, together with the manner in which the same is to be or may be performed,
we would have it understood that we do not claim any of the parts hereinbefore
described separately or apart from the combination thereof in our improved loom ;
but what we do claim as the Invention secured to us by the hereinbefore in part
recited Letters Patent is,-
First. The improvements in power looms, herein before described and illustrated
in the Drawing hereunto annexed, or any mere modification thereof, whereby we
are enabled to weave looped or terry fabrics in such power looms.
Secondly. The application to or use of in power looms of the parts or apparatus

page_text: marked respectively 12, 13, and 14 in the Drawings hereunto annexed, or any mere
modification thereof, for operating the stop handle of such looms, as and for the
purposes herein before described or mentioned; and
Thirdly. The application to or use of in power looms of the parts or apparatus
marked respectively 26 and 27 in the Drawings hereunto annexed or any mere
modification thereof, for applying the brake marked 30 or any similar brake in
such looms, as and for the purposes hereinbefore described or mentioned.
In witness whereof, I, the said Arthur Edward Walker, for and on behalf
of myself and the said Wright Haigh and Joseph Brook, have hereunto set
my hand and seal, this Sixth day of February, in the year of our Lord One
thousand eight hundred and eighty.
