IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1875

page_text: LETTERS PATENT to Enoch Openshaw Taylor, of Marsden, in the
County of York, Engineer, for the Invention of "IMPROVEMENTS IN
LOOMS FOR WEAVING."
Sealed the 13th August 1875, and dated the 8th March 1875.
PROVISIONAL SPECIFICATION left by the said Enoch Openshaw
Taylor at the Office of the Commissioners of Patents, with his
Petition, on the 8th March 1875.
I, ENOCH OPENSHAW TAYLOR, of Marsden, in the County of York,
Engineer, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
The improvements relate to means for giving increased facility in the
use of rising and falling shuttle boxes, arranged in series for effecting
changes of the shuttles in looms, and the object of the Invention is to
give ease and steadiness by controlling the movement of such series of
boxes in their falling motion to their respective stops for the selection
desired.

page_text: The movements of the series of boxes for the desired selection are
effected by ordinary means, by in carrying out my Invention I apply
another lever capable of sustaining and controlling the descent of the
series of boxes, and which lever is capable of movement sideways on an
axis of motion carried by or working with the lever or such like arrange-
ment used in actuating the boxes, whilst towards its other end it carries
a truck or bowl in position to be operated upon by any one of a series of
rises on another tappet fixed on the tappet shaft. This additional lever is
borne on by a spring or other suitable pressure, so as to have a tendency
for its truck or bowl to be brought under the highest portion of the tappet
acting with it, and this tappet is formed with an inclined side surface, so
that when the series of boxes at the selection being made are to be in
any other than the highest position this side inclined surface will act on
one side of the truck or bowl of this extra lever and move that lever, so
that such truck or bowl will come under a corresponding rise of the
extra tappet, and the action of such portion of the tappet will by its
form be gradually to let the box down to the stop then in position for it,
and this will be the effect of the action of each of the rises on this extra
tappet on the truck or bowl of this extra lever from the highest to a
lower position.
SPECIFICATION in pursuance of the conditions of the Letters ratent,
filed by the said Enoch Openshaw Taylor in the Great Seal Patent
Office on the 7th September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ENOCH
OPENSHAW TAYLOR, of Marsden, in the County of York, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of March, in the year of our Lord
One thousand eight hundred and seventy-five, in the thirty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Enoch Openshaw Taylor, Her special license that I,
the said Enoch Openshaw Taylor, my executors, administrators, and
assigns, or such others as I, the said Enoch Openshaw Taylor, my exe.
cutors, administrators, and assigns, should at any time agree with, and

page_text: 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," upon the condition (amongst others) that I, the
said Enoch Openshaw Taylor, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Scal Patent Office
within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Enoch Openshaw Taylor, 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 improvements relate to means for giving increased facility in the
use of rising and falling shuttle boxes, arranged in series for effecting
changes of the shuttles in looms, and the object of the Invention is to
give case and steadiness by controlling the movement of such series
of boxes in their falling motion to their respective stops for the selection
desired.
The movements of the series of boxes for the desired selection are
effected by ordinary means, but in carrying out my Invention for
controlling the descent of the series of boxes, a movcable truck or
bowl carried by or working with the lever or such like arrangement
used in actuating the boxes is applied in position to be operated upon
by any one of a series of rises on another tappet fixed on the tappet
shaft. This truck or bowl is borne on by spring or other suitable
pressure so as to have a tendency to be brought under the highest
portion of the tappet acting with it, and this tappet is formed with
an inclined side surface, so that when the series of boxes at the
selection being made are to be in any other than the highest position,
this side incline surface will act on one side of the truck or bowl and
move that truck or bowl, so that such truck or bowl will come under a
Corresponding rise of the extra tappet, and the action of such portion of
the tappet will by its form be gradually to let the box down to the stop

page_text: then in position for it, and this will be the effect of the action of each of
the rises on this extra tappet on the moveable truck or bowl from the
highest to a lower position.
But that the Invention may be fully understood I will by the aid of
the accompanying Drawings proceed to describe means pursued by me 5
in carrying the same into effect.
view of a loom with adaptations thereto, according to my Invention.
Figures 3 and 4 show details separately and to a larger scale.
The class of loom to which my improvements are shown applied is
that known as Hirst and Hollingworth's. In each of the Figures the
same letters indicate corresponding parts.
a is the main framing, and ₺ the main or crank shaft. On this shaft
bis applied the bush c, and this bush is held in position by a feather
applied between it and the shaft b, in order that whilst this bush is
controlled to revolve with the shaft b, it may be capable of endway
motion on that shaft. On this bush c is applied the rim or flange c¹ by
action on which the sliding of the bush is effected, and on this bush c is
also applied the boss and series of cams or cam surfaces d³, ďª³, d³, d³, d³.
The flange cis acted upon for its endway motion on the shaft 6 for tho
shifting of the cams d by means of the lever o, which is supported to
turn on the pivot o¹, and one end of of which is forked to embrace the
flange c', whilst the other end o³ is by suitable connecting rod or other
means and jacquard or other suitable pattern surface, such as is well
known capable of being actuated to slide the bush c on the shaft b, and
by that means as desired bring any one of the cam surfaces d', d', or d',
over the bowl, which with its shaft i is capable of revolving freely in
bearings carried by the lever j. This lever ; is supported at one of its
ends to rock on the stud j', whilst at its other end it is by pin joint
connected to the lower end of the rod 7, the upper end of which is at m²,
connected to the one end of the rocking lever m, which lever mis
supported to rock on the fixed stud m², and at its front end by means of
the connecting rod supports the series of shuttle boxes at that end of
the loom; q is the stop rod or lever which is supported to turn or rock
on the fixed stud q', and at its upper end q is notched to act on one or
P

page_text: other of the adjustable studs or projections n³, n², n³, or n', in order to
to sustain that end of the lever correctly for the desired shuttle box
of the series, being in a line with the race of the lay, whilst the lower
end q is capable of being acted upon by one or other of the cam
surfaces d, d, or d³, and the object of my Invention is to obtain an
easy descent without vibration or shock from one to others of these stops
n³, n³, n³, n', as from n¹ to n¹³, or other intermediate stop. For this
purpose there is keyed or otherwise fixed on the shaft 6 the boss c, to
which is applied with capability of adjustment the series of cams f, and
on the shaft is applied the pulley wheel 7 which is not only capable of
revolving on that shaft i, but also of sliding endwise thereon, so that it
may be brought under any one of the surfaces f¹, f, or f³, of the series
of cams f. Each of these cam surfaces f¹, f, and f³, has the leading
part of it f* formed full so as quickly to come into operation, and then
from its highest point it gradually recedes to the end of its course. The
inner side surfaces of the first operating ends of these cams f¹, ƒ”,ƒ³, arc
also inclined, as shown at f³. The bowl g is constantly borne upon
with a tendency to bear it from the end framing of the loom by the
outer end of the lever, which is supported to turn on the fixed stud k¹
carried by a bracket from the lever j, and is acted upon by the spring /
with a tendency to bear it and the pulley g forwards as stated.
In order however that the operation of the parts may more readily
appear I will suppose by way of illustration that the cam surface & in
the revolution of those cams acts upon the lower end q³ of the lever q,
so as to remove the notch q³ at the upper end thereof from the stop m²,
and bring it in a position to receive the stop n² or that which will bring
the top box but one of the series in a line with the race.
Then as soon
as the cam & has disengaged the lever q, the cam f¹ will act on the bowl g
to resist the too sudden tendency of the boxes to fall with a shock, and
will thereby lower them gradually the whole distance, until the cam
ď having ceased to act on the lever q it arrests or receives the stop n².
I
The bowl in the next rotation of the cams will in consequence of
the altered position of the shuttle boxes be nearer the shaft b, and
though still by the action thereon of the spring lever Z be in a line with
the cam f', but as these cams begin to act on that bowl their inclined or
taper sides at f³ will cause the bowl g to slide along the shaft i until
that bowl is clear of the cam f³, when the taper part of the cam will
place the bowl yg in position to run into the groove of which ever of the

page_text: cams f¹, fa, may next be required for the position of the boxes as left by
the last operation.
The edges of the respective cam surfaces are grooved or recessed to
ensure their acting correctly with the corresponding surfaces of the bowls
or surfaces acted upon, or the grooves or recesses may be in the surfaces
of the pulleys or surfaces acted upon, and the corresponding V or pro-
jection on each of the cam surfaces. Although I have shown the parts
adapted to working with changes for four shuttles, the same will readily
be varied to working with other number of shuttle chambers.
Having thus described my Invention and means which I adopt in
carrying the same into effect, I would have it understood that I do not
confine myself to the precise details as shown and described, as these
may be varied without departing from the peculiar character of the
Invention; but what I do claim is the arranging or combining parts,
whereby the letting down of the series of shuttle boxes in arrangements
of looms of the character referred to may be gradually and surely
effected, substantially as described.
In witness whereof, I, the said Enoch Openshaw Taylor, have here-
unto set my hand and seal, this Sixth day of September, in the
year of our Lord One thousand eight hundred and seventy-
fivc.
ENOCH OPENSHAW TAYLOR. (L.S.)
