RICHARD LONGDEN HATTERSLEY of Keighley in the County of York, Machine
Maker, and JAMES HILL of the same place, Mechanic. IMPROVEMENTS IN LOOMS
FOR WEAVING AND IN APPARATUS EMPLOYED IN CONNECTION THEREWITH "
This Invention relates
Firstly, to an improved arrangement of mechanism for operating rising or
oscillating shuttle boxes.
For rising and falling boxes we employ the ordinary shuttle box connected by a
vertical rod to the shuttle box lever which is hinged to the lower portion of the
end frame of the loom. In the end of the box lever is a slot within which is
fitted a sliding block through which passes a crank pin fixed to the face of a
toothed pinion mounted on a stud and gearing with a toothed wheel of larger
diameter also mounted on a stud fixed in the end frame. Upon pins or studs
placed at opposite points upon the face of the larger wheel are mounted hooked
rods or catches which extend upwards and pass through a slotted lever mounted
on a fulcrum near the front of the loom and resting midway upon a cam or tappet
fixed on the low shaft which cam imparts a rising and falling motion. to the lever
and at each rising motion one or other of the catch rods is caused to engage with
the edge of the slot which is formed for the purpose and the plate wheel is caused
to oscillate and thereby impart a like oscillating motion to the pinion carrying the
crank piu which works in the slotted end of the box lever which is thus raised
and lowered the termination of each movement being either directly over or under
the centre of the pinion in which position there is no tendency of the lever to

page_text: move until further power is applied and thus the arrangement is self locking.
The catch rods may be actuated by any of the ordinary jacquard or pegging
apparatus in ordinary use.
Secondly. Our Invention relates to the use of mechanism similar to what bas
been already described for the purpose of operating the "picking" apparatus. For
this purpose the crank pin in the smaller toothed wheel is connected by a double
jointed rod to the ordinary lever which places the picking tappits in and out of
position.
Thirdly. Our Invention relates to improvements in the mechanism for indicating
the change of the shuttle boxes and picking of shuttles in looms wherein either
rising and falling boxes or oscillating boxes are employed.
According to our present improvements the shuttle boxes may be arranged to
work either together or independently of each other the operation being indicated
by peg lags or cards which pass over a cylinder placed upon the same shaft as the
peg cylinder which serves to control the heald mechanism. The two cylinders
revolve independently of one another the heald cylinder being fast on the shaft
and caused to revolve at each pick by the usual arrangement of bevil wheels whilst
the shuttle box cylinder is mounted on a loose boss on the same shaft and actuated
by peg wheel and peg plate. The pegs in the plate are removable and their
number is such that the two cylinders may be caused to revolve together, or the
box cylinder may be moved one notch or lag or more whilst the heald cylinder
makes a complete revolution or the box cylinder may be stopped at any time, thus
enabling us to effect a great variety of changes with very little extra mechanism.
Fourthly. Our Invention relates to apparatus for operating the ordinary square
barrel employed in jacquard apparatus for carrying chains of perforated cards.
At one end of the barrel we employ the ordinary catches and pegs for turning the
barrel a quarter of a revolution and at the other end of the barrel we employ double
sets of catches together with a wheel carrying two sets of pegs and other wheels so
regulated as to size that a quarter revolution of the peg wheel shall impart a half
revolution to the barrel. By this arrangement we are enabled to weave from
alternate cards, that is to say a chain of eight cards we can weave the whole series
in succession or from 1, 3, 5 and 7 for any length of time and then by a change of
catch we can weave from 2, 4, 6 and 8 thus producing three patterns from one
set of cards. Each catch has its own duplicate for lagging back and the tappits for
engaging and disengaging them are so arranged that it is impossible to substitute
one for another.

Firstly. To an improved arrangement of mechanism for operating rising or
oscillating shuttle boxes.
For rising and falling boxes we employ the ordinary shuttle box connected by a
vertical rod to the shuttle box lever which is hinged to the lower portion of the
end frame of the loom. In the end of the box lever is a slot within which is fitted
a sliding block through which passes a crank pin fixed to the face of a toothed
pinion mounted on a stud and gearing with a toothed wheel of larger diameter
also mounted on a stud fixed in the end frame. Upon pins or studs placed at
opposite points upon the face of the larger wheel are mounted hooked rods, or
catches which extend upwards and pass through a slotted lever mounted on a
fulcrum near the front of the loom and resting midway upon a cam or tappit fixed
on the low shaft, which cam imparts a rising and falling motion to the lever and
at each rising motion one or other of the catch rods is caused to engage with the
edge of the slot which is formed for the purpose, and the plate wheel is caused to
oscillate and thereby impart a like oscillating motion to the pinion carrying the
crank pin which works in the slotted end of the box lever which is thus raised and
lowered, the termination of each movement being either directly over or under the
centre of the pinion in which position there is no tendancy of the lever to move
until further power is applied and thus the arrangement is self locking. The catch
rods may be actuated by any of the ordinary jacquard or pegging apparatus in
ordinary use.
Secondly. Our Invention relates to the use of mechanism similar to what has
been already described for the purpose of controlling the operation of the picking
tappits apparatus. For this purpose the crank pin in the smaller toothed wheel is
connected by a double jointed rod to the ordinary lever which places the picking
tappits in and out of position.
Thirdly. Our Invention relates to improvements in the mechanism for indicating
the change of the shuttle boxes and picking of shuttles in looms wherein either
rising and falling boxes or oscillatory boxes are employed.
According to our present improvements the shuttle boxes may be arranged to
work either together or independantly of each other, the operation being indicated
by peg lags or cards which pass over a cylinder placed. upon the same shaft as the
peg cylinder which serves to control the heald mechanism. The two cylinders
revolve independantly of one another, the heald cylinder being fast on the shaft
and caused to revolve at each pick by the usual arrangement of bevil wheels, whilst
the shuttle box cylinder is mounted on a loose boss on the same shaft and actuated
by peg wheel and peg plate. The pegs in the plate are removable and their number
is such that the two cylinders may be caused to revolve together, or the boss
cylinder may be moved one notch, or lag, or more; whilst the heald cylinder makes
a complete revolution, or the boss cylinder may be stopped at any time, thus
enabling us to effect a great variety of changes with very little extra mechanism.
Fourthly. Our Invention relates to apparatus for operating the ordinary square
barrel employed in jacquard apparatus for carrying chains of perforated cards.

page_text: At one end of the barrel we employ the ordinary catches and pegs for turning the
barrel a quarter of a revolution, and at the other end of the barrel we employ
double sets of catches together with a wheel carrying two sets of pegs, and other
wheels so regulated as to size, that a quarter revolution of the peg wheel shall
impart a half revolution to the barrel. By this arrangement we are enabled to
weave from alternate cards, that is to say in a chain of eight cards we can weave
the whole series in succession or from 1, 3, 5, and 7 for any length of time, and then
by a change of catch we can weave from 2, 4, 6 and 8 thus producing three
patterns from one set of cards. Each catch has its own duplicate for lagging back
and the tappits for engaging and disengaging them are so arranged that it is
impossible to substitute one for another. By means of a slight modification in the
driving apparatus, this system of pegging from alternate lags can be carried out in
ordinary heald machines.
In order that our Invention may be more fully understood, we hereto annex
five Sheets of Drawings marked with. figures and letters of reference. Fig 1
represents that part of our Invention which relates to the improved arrangement
of mechanism for operating rising and oscillating shuttle boxes, a rising box loom
being chosen for the purpose of illustration. A are the shuttle boxes supported in
the frame B by means of the rod C which is connected to the end of the box
lever D in the usual manner. In the opposite end of the lever D a slot is formed
for the purpose of containing the sliding block E through which passes a crank
pin a formed on a plate secured to the face of the pinion F which is mounted
loosely on a stud fixed in the end frame of the loom. Upon a similar stud is
mounted a larger toothed wheel G gearing with the pinion F which carries two
crank pins c to which are attached the catch rods H, which pass through a slot d
in the lever J the said lever being mounted upon an adjustable spring fulcrum K
and caused to rise and fall by means of a cam L on the end of the low shaft of
the loom. The catch rods H can be operated upon by the levers M in accordance
with the indications of a chain of peg-lags on the cylinder M' whereby one or
other of the rods H is caused to engage with the "knife" or angular edge of the
lever J, the other one being preserved from contact therewith by the spiral spring N.
Then as the lever J rises it will carry the engaged rod with it and thereby turn
the wheel G partially round, a quarter revolution of such wheel being sufficient to
impart a half revolution to the pinion F. According to the drawings such a half
revolution would place the crank pin a directly over the upper dead centre of the
pinion F from which position it would have no tendancy to move either one way,
or the other and thus beyond the ordinary brake P all locking apparatus will be
dispensed with.
In Fig. 2 and 24 which are end, and portion of back elevation of a loom, we have
shewn the manner in which a form of apparatus similar to the one already
described may be employed for the purpose of controlling the operation of the
picking tappits, the parts marked with the same letters are identical in their
operation with those shewn in Fig 1. In this case the crank pin a on the
pinion F is connected by means of a double jointed link R with the lever S and
the motion imparted thereto by the rotation of the pinion F is conveyed by the
rods and levers T to the tappits U which are placed in, or out of position for
picking, according to the arrangement of the peg-lags on the cylinder M¹.
Figs. 3 and 4 are back elevation and plan of the heald machine together with
the additional apparatus devised by us for indicating the changes of the shuttle
boxes and picking tappits, such additions being equally applicable to looms having
either rising and falling or oscillatory shuttle boxes. In general construction the
machine is similar to that described and shewn in Figs. 1 and 7 of the Drawings
in Specification of Letters Patent granted to us, and bearing date the 5th of
April 1879 Number 1351.. In the Drawings hereto annexed A represents the

mounted fast on the shaft a and is driven by the bevil wheels b, c. For indicating
the shuttle box and picking changes we employ a second cylinder B and a crown

page_text: wheel both of which are mounted on a loose boss on the shaft a. To the bevil
wheel b is fixed a peg plate D in which are a number of holes corresponding to the
number of teeth or notches in the wheel C. If a peg be placed in each of these
holes the bevil wheels b, c, and the plate D and crown wheel C will revolve
simultaneously, but if one or more pegs be omitted from the plate D the crown
wheel C will remain stationary until the plate has revolved sufficiently to bring
the next peg of the series into gear, and by removing all the pegs but one the
motion of the crown. wheel will be reduced to the extent of one notch for each
revolution of the bevil wheels b, c and the movements of the cylinders A and B
will be correspondingly varied. It will thus be seen that by these means, we can
not only control the shuttle boxes, and picking tappits by a comparatively short
chain of lags but by the use of the variable peg-plate we can produce a greater
variety of changes than could otherwise be effected by the same number of lags
and the whole of the advantages are obtained with the use of very little extra
mechanism.
In Fig. 5 and 6 which are end elevation and detail in plan of a jacquard machine
we have shewn our improved arrangement of mechanism for operating the barrel,
the object of this part of our Invention being to work from the alternate cards of a
series as well as from the whole series in succession. In the Drawings the ordinary
catches for turning the barrel round a quarter of a revolution are not shewn; being
placed at the other end of the machine, but to work from alternate cards, it is
necessary to turn the barrel half a revolution, and to effect this we mount on the
axis of the barrel a toothed pinion a which gears with a pinion b of the same size
and a similar pinion c on the same axis gears with a toothed wheel d of twice its
diameter. In the wheel & are eight pegs e four on each side placed alternately.
Each set of pegs has the usual pair of catches f,f¹, g, g¹ for "lagging" the cylinder
forward and backward as required. The operation is the same as usual only by
reason of the multiplying train of wheels a, b, c, d, the cylinder is caused to revolve
half a revolution instead of a quarter. The cams h and j are jointed together at
right angles to each other and can be turned by strings K so as to bring either pair
of catches into operation. In lagging back it is impossible for the Weaver to
bring the wrong catch into operation as each pair are connected together by cords n
which are continued downwards, and joined together round a pulley block m to
which a single cord is attached. By this arrangement the operator is compelled to
pull the upper catch out of gear at the same time as he puts the lower one into
gear, and the vertical cam h or j will always keep one pair inoperative. When it
is desired to weave from the whole of the cards in succession, the catches f; f¹, g, g¹
are kept out of gear by tyeing the short ends of the levers together, but for alternate
pegging the single pair are rendered inactive in a similar manner, and one of the
pairs ffg, g' brought into operation. We are thus enabled to weave from the
whole series 1, 2, 3, 4 or from the series 1, 3, 5, 7 or 2, 4, 6, 8, and so on until the
chain is exhausted thus producing three distinct patterns from one set or chain of
cards. This system of alternate pegging is also applicable to heald machines of the
kind described and illustrated in Figs. 3, 4, and 4ª. The cylinders A and B are
octagonal and if the eight notched crown wheel E be removed, and one with four
notches substituted the cylinder A will revolve a quarter of a revolution at each
movement, and thus present the alternate lags to the "feelers "F. In changing
however from one pattern or series of lags to another the first movement of the
cylinder will be only to the extent of one lag and this movement will require to be
performed by the Weaver. For this purpose we fix a star wheel G on the end of
the shaft a (see Fig 5). The shaft serves as the fulcrum for a slotted lever H in
which is a pin which enters a fixed cam groove J. The lever H is connected by
rod R to the quadrant lever Land it will be seen that as the lever L is moved from
side to side the pawl or catch e on the end of the lever H is caused to enter one of
the notches in the star wheel, turn the same round one eighth of a revolution and
then disengage on the opposite side; the cylinder A revolving to a similar extent.
At the next change of pattern this operation will have to be repeated, the cylinder

page_text: of course moving in the opposite direction. As it is very desirable to move the
cylinder A without disturbing the cylinder B and the driving gear, the wheel c
instead of being keyed fast on the shaft a is secured by a spring clutch M so that
when the shaft is turned round by the Weaver, the clutch slips out of gear and
revolves to the extent of one tooth whilst the wheel c remains stationary.
In witness whereof I the said Richard Longden Hattersley. for and on behalf
of myself and the said James Hill have hereunto set my hand and seal
this Fifteenth day of January in the Year of our Lord, One thousand
eight hundred and eighty three.
