Office of the Commissioners of Patents on the 9th May 1883.
ROBERT WOLFE SUTLEFFE of Bouverie Street in the city of London, Engineer
"IMPROVEMENTS IN SELF ACTING READERS FOR THE JACQUARD
"
:
My invention relates to improvements in self acting readers for the jacquard,
the object of the improvements being to simplify the construction and manipulation
of the reader and to render its construction less costly.
In carrying out my invention I employ a suitable frame on each side of which
a bracket is provided. On one of the brackets is a slotted frame fastened to it at
right angles; in the slotted frame is placed a screw having a fine thread. This
screw is provided with a handle in front, and a washer, and nut at the back end,
and passes through a tapped nut the end of which forms an adjustable fulcrum for
a slotted lever through which it passes'; the lever carries a stud at one end; this
stud takes into the helical groove of a helical cam wheel of special construction
hereinafter described, fixed at the right hand end of a main cross shaft; the other
end of the lever has a slot to receive a rod which depends from a horizontal bar
carrying the pointers hereinafter described. The helical cam wheel is provided
with a sliding piece, which when the punching of one card has been completed
allows of the return of the pointers and slotted lever to the position which they
occupy when commencing to punch a card and prevents any possibility of the pin
binding at this point in its course as has hitherto been the case when a solid cam
has been employed; pins are provided on either side of the helical cam wheel for
shifting the sliding piece at the required moments as the cam wheel rotates. In
the other bracket and on the left hand end of the main shaft, I mount a grooved
wheel provided with a projection capable of adjustment radially by means of a
nut and screw; this projection actuates a short bent lever on a rocking shaft ät
73

page_text: each revolution of the main shaft and thereby operates pawls by means of con-
necting rods and thus moves certain toothed wheels and the front rollers forward
to the required extent, which extent is regulated by adjusting the projection by
means of the hereinbefore described nut and screw. By this arrangement, I
dispense with the slotted lever and cam wheel hitherto employed for this purpose
in self acting readers and thus considerably simplify the construction of the machine
at this part and diminish the cost of its manufacture.
At a suitable point on the main shaft is keyed a ratchet wheel; on the boss of
this wheel is a triangular shaped plate, to which is fixed a pin or stud and on
which is pivotted a weighted pawl; this pawl takes into the teeth of a ratchet
wheel; at the back of the ratchet wheel and working on a pin screwed into a
projection cast on the frame is a spring catch formed with a tooth or projection
which also takes into the teeth of the ratchet wheel, this catch is of a semi-
circular form following part of the circumference of the ratchet wheel. A pin serves
to raise the tooth or projection free of the teeth of the ratchet wheel when the
ratchet wheel is to be moved forward by the pawl. To the lower angle of the
plate is jointed a connecting rod, the lower end of this connecting rod is jointed
to an oscillating lever which has its bearing or fulcrum on a small shaft fixed to
the two side frames and just behind and below the card frame. The other end of
the oscillating lever is jointed to a rod the lower end of which is jointed to a treadle
which works on a shaft. The back end of the treadle is continued beyond
the shaft and to the end at each side are jointed connecting rods which
are jointed at their upper ends to two levers pivotting on brackets and provided
at their free ends with a bar the ends of which work in guide plates
and receive the lower ends of rods or bolts which operate the punches. The
connecting rods have each a strong spiral spring fastened to them and serving to
raise the treadle when it is released from the pressure of the foot; the lower ends
of these springs are fastened to each side of the treadle a short distance from the
front of the machine. Below the main shaft is a bar fixed to each side of the
frame and near the centre of this bar is bolted a slotted bracket in which works a
vertical screw having a fine thread this screw carries a pin at its upper end which
pin forms the fulcrum of a slotted vertical lever the said fulcrum being capable of
adjustment vertically by turning a vertical screw either to the right or to the left
as required; this arrangement allows of the fulcrum of the lever being adjusted to
regulate the extent of travel of the card frame; through the top end of the lever
is fixed a pin one end of which works in a slotted plate having its lower end
bolted or cast on a bracket and the other end having a loose bearing on the main
cross shaft. The other end of the pin works in a groove of a cam wheel keyed on
the main shaft. The lower end of the lever is jointed to a rod which is jointed to a
rod working in a bearing bolted to the horizontal cross bar. This rod is provided
with a spiral spring one end of which bears on the bearing and the other end on
a collar formed on the rod; this spring is for assisting to carry the card frame back
to its starting point as each card is punched, the front end of the rod being fastened
to the card frame. The perforated die plate is bolted to the front of the frame;
immediately above is what is called the stock plate with corresponding perforations
and holding the row of punches; above the stock plate is the punching plate below
which is a row of sliding levers having parts of their surfaces cut away on their
underside, these levers corresponding in number with the punches. Cords or chains
are fastened to the levers and pass round pulleys at the rear end of the same and
connect with the indices or pointers; the said cords or chains pass over pulleys in the
pointers and are attached to a spring rod sliding within the pointer; the cords or
chains serve to draw backwards the punching levers for the purpose hereinafter
described, the spring carrying the rod back so as to slacken the cords or chains when
it is released; springs cause the punching plate and punches to return to their
normal position after each motion of the treadle; bolts are fixed to the punching plate
and pass through the die plate the lower ends being jointed to the rod or bar on
the levers as hereinbefore described. On the shaft works an oscillating double
४

page_text: crank, the top crank fits accurately along the whole line of punching levers and
serves to return them to their normal position after each punching operation in the
following manner :-the lower crank is forced backwards at the return of the treadle
by a triangular shaped frame bolted at its base to each side of the treadle, which
frame presses against a spring tongue fitted on the crank and forces another crank
against the punching levers the spring tongue works on a joint which allows the.
tongue to give way and the frame to pass it when the treadle is depressed, but to
remain rigid when the frame meets it on the upward movement of the treadle.
I can effect the regulation and adjustment of the pointers laterally in the
following manner.
I form each of the pointers hollow and with a slot on each side throughout
nearly its entire length; the centre pointer is fixed to the index frame; within
the other pointers slide two short rods to each of which is jointed a rod the other
end of of the rods being jointed to the end of the next pointer; the centre pointer
receives the ends of the rods of the pointers on both sides the sliding rods are each
provided with a hole through which holes are passed rods capable of being moved
towards or away from each other by any suitable means such as by right and left
handed screws at their ends.
The operation of the improved self acting reader is as follows:-
The pattern or design to be read off having been placed on the rollers in the
usual manner the projection on the grooved wheel is adjusted by means of the nut
and screw so as to regulate the travel, of the pattern on the rollers according to
the scale of the divisions of the pattern paper; the pointers are then adjusted
laterally to the scale of the divisions of the pattern by means of the right and left
handed screws at the ends of the rods which will be caused to approach or move
away from each other according to the direction in which the screws are turned;
the rods sliding in the pointers will thus by means of the other rods draw the
pointers towards or away from each other, and the pointers when thus set will
remain rigidly in position and equi-distant from each other. The card to be
punched is then placed as usual on the card plate, the cords attached to the pointers
(which indicate the particular colour being read in) are slightly pulled by the
operator and will thereby draw back their corresponding levers into position for
punching the holes in the card and the treadle being now depressed the bar will
be lowered by means of the levers and will draw down the rods or bolts, and with
them the punching plate which pressing on the levers will cause such of the said
levers as have been drawn backwards by the cords as hereinbefore described to
force their respective punches through the card, the remaining punches will enter
cut away parts of the levers and will therefore not be subjected to the pressure of
the levers; the cut away parts limit the movement of the levers.
By the herein before described arrangement of cords and pulleys connecting the
pointers with the punching levers I avoid the necessity of the operator having to
turn his eyes from the pointers to the corresponding keys which has hitherto been
the cause of frequent mistakes and consequent waste of the cards thus spoiled and
loss of time. The treadle in being depressed will by means of the rods and lever
have raised the plate and with it the weighted pawl which will thereby have been
raised out of the teeth of the ratchet wheel; the plate in rising will raise the tooth
or projection also out of the teeth of the ratchet wheel by the pin which passes
under and raises the spring catch carrying the tooth; the treadle being now released
from the pressure of the foot will draw down the pawl and thus rotate the ratchet
wheel to the extent of one tooth; the main shaft being thus rotated to a corre-
sponding extent will partially rotate the helical cam wheel the groove of which will
operate the slotted lever and the horizontal bar carrying the pointers, so as to move
the pointers one single square of the pattern from right to left as hitherto. The
main shaft in rotating also carries with it the cam wheel which by means of the
pin working in the groove of the same and in the slot in the plate operates the lever
so as to cause its tail end, by means of rods, to draw the card frame backwards to
the required extent after the row of perforations has been punched in the card.

page_text: When the treadle is released the punching plate and punches are raised to their
normal position by springs and the treadle in rising carries the frame against the
spring tongue on the double crank and presses the levers back to their original
position.
The cords attached to the pointers corresponding with the particular colour to be
next read in are then pulled and the treadle is again depressed and so on as herein-
before described until the perforation of the card is completed. When the
perforation of one card has been completed and one line of the pattern read off the
pointers are brought back to their starting position by the sliding piece in the
helical cam wheel (into one end of the groove of which sliding piece the pin will
have entered) coming in contact with the other. pin as the helical cam wheel
revolves whereby the sliding piece is pushed into a position such that the other
end of the groove therein shall meet the helical groove in the wheel into which as
the operation of the machine continues the pin will then pass carrying with it the
slotted lever; the pin as the wheel continues to rotate then pushes back the sliding
piece into its former position. The card frame having now been drawn back to its
full extent during one revolution of the main shaft it is returned to its starting
point by the pin on the lever travelling through the straight portion of the groove
in.the.cam.wheel the backward motion of the lever being assisted by means of the
spring on the rod. The pattern is moved forward on the rollers to the extent of
one line of squares by the projection on the grooved wheel coming against and
moving the lever outwards from the wheel; this motion operates the pawls, by
means of rods, and the toothed wheels and rollers are rotated to the required extent.
The perforated card is now withdrawn from the card frame and a fresh card fixed
therein and the herein before described operation is repeated and so on until the
whole of the pattern has been read off.

ROBERT WOLFE SUTLEFFE of Bouverie Street in the city of London, Engineer
IMPROVEMENTS IN SELF-ACTING READERS FOR THE JACQUARD "
My invention relates to improvements in self-acting readers for the jacquard, the
object of the improvements being to simplify the construction and manipulation of
the reader and to render its construction less costly.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawings in which figure 1, sheet 1,
represents a plan of a self acting reader for the jacquard constructed according to
my improvements the pointers or indices being removed for the sake of clearness;
figure 2, sheet 1, is an end view of the same and figures 3 and 4 sheet 1, are
sections on the lines A, B, and C D, respectively of figure 1; figure 5, sheet 1, is a
detached sectional view of the arrangement I employ for setting the punching
levers; figure 6, sheet 1, sectional elevation shewing an arrangement of pointers
or indices which I can employ with my improved reader. figure 7, sheet 2,
represents a portion or section of a pattern or design which is given as an illus-
tration to shew how a design may be read in; figure 8, sheet 2, represents the
said portion of a pattern fixed on one of the rollers of the machine ready to
commence the operation of reading in the same; figure 9, sheet 2, is a view of a
card perforated by the machine and corresponding with the first row of the said
pattern when the said row has been read in; figure 10 sheet 2, is a sectional
detail shewing the position of the punches and parts operating the same when the
parts of the machine are in their position of rest and before the punches have been
depressed; figure 11, sheet 2, is a similar view showing the position occupied by
the said parts when the punches have been depressed; figures 1, to 5 are drawn
to a scale of about one fourth full size and figures 6 to 11, are drawn full size.
Similar letters in all the figures represent similar parts.
In carrying out my invention I employ a suitable frame a, on each side of which
a bracket is provided such brackets being marked b, and c, respectively. On the
bracket b, is a slotted frame d, fastened to it at right angles; in the slotted frame d,
is placed a screw e, having a fine thread. This screw e, is provided with a
handle f, in front, and a washer and nut at the back end, and passes through a
tapped nut g, the end of which forms an adjustable fulcrum for a slotted lever h,
through which it passes; the lever h, carries a stud i, at one end; this stud takes
into the helical groove of a cam wheel j, of special construction herein-after
described, fixed at the right hand end of a main cross shaft k; the other end
of the lever h, has a slot B, to receive the rod 1, which depends from the horizontal
bar m, carrying the pointers n, hereinafter described. The helical cam wheel j, is
provided with a sliding piece o, which when the punching of one card has been
completed allows of the return of the pointers n, and slotted lever h, to the position
which they occupy when commencing to punch a card and prevents any possibility
of the pin i, binding at this point in its course as has hitherto been the case
when a solid cam has been employed; p, and p¹, are pins on either side of the
helical cam wheel j, for shifting the sliding piece o, at the required moments as
the cam wheel rotates. In the bracket c, and on the left hand end of the main
shaft k, I mount a grooved wheel r, provided with a projection ¹, capable of
adjustment radially by means of a nut 8, and screw t; this projection r¹, actuates
a short bent lever u, on a rocking shaft v, at each revolution of the main

page_text: Y,
and
shaft k, and thereby operates the pawls w, by means of the connecting rods x,
and thus moves the toothed wheels z, z', 22, and front rollers A, A', forward to the
required extent, which extent is regulated by adjusting the projection r', by means
of the hereinbefore described nut 8, and screw t. By this arrangement I dispense
with the slotted lever and cam wheel hitherto employed for this purpose in self
acting readers and thus considerably simplify the construction of the machine at
this part and diminish the cost of its manufacture.
At a suitable point on the main shaft k, is keyed a ratchet wheel a¹; on the boss
of this wheel is a triangular shaped plate b', to which is fixed a pin or stud c', and
on which is pivotted a weighted pawl d'; this pawl takes into the teeth of the
ratchet wheel a¹; at the back of the ratchet wheel a³, and working on a pin e¹,
screwed into a projection cast on the frame a, is a spring catch f¹, formed with a
tooth or projection g', which also takes into the teeth of the ratchet wheel a', this
catch is of a semi-circular form following part of the circumference of the
ratchet wheel a¹. The pin c¹, serves to raise the tooth or projection gl, free of the
teeth of the ratchet wheel a¹, when the ratchet wheel is to be moved forward by
the pawl d. To the lower angle of the plate 6', is jointed a connecting rod h¹;
the lower end of this connecting rod is jointed to an oscillating lever , which has
its bearing or fulcrum on a small shaft j', fixed to the two side frames a, and just
behind and below the card frame k¹. The other end of the oscillating lever i, is
jointed to a rod 1, the lower end of which is jointed to the treadle m', which works
on the shaft n. The back end of the treadle is continued beyond the shaft n³, and
to the end at each side are jointed connecting rods o¹, and p2, which are jointed at
their upper ends to two levers q', pivotting at 2, on the brackets s¹, and provided
at their free ends with a bar t, the ends of which work in the guide plates u¹, and
receive the lower ends of rods of bolts 2, t2, which operate the punches.
The connecting rods o¹, and p², have each a strong spiral spring v, vl, fastened to
them and serving to raise the treadle when it is released from the pressure of the
foot, the lower ends of these springs are fastened to each side of the treadle m³,
a short distance from the front of the machine. Below the main shaft k, is a
bar w¹, fixed to each side of the frame a, and near the centre of this bar is bolted a
slotted bracket x, in which works a vertical screw y', having a fine thread this
screw carries a pin a², at its upper end which pin forms the fulcrum of a slotted
vertical lever 62, the said fulcrum being capable of adjustment vertically by turning
the vertical screw y¹, either to the right or to the left as required; this arrangement
allows of the fulcrum of the lever b², being adjusted to regulate the extent of travel
of the card frame ¹; through the top end of the lever b², is fixed a pin c², one end
of which works in a slotted plate d³, having its lower end bolted or cast on the
bracket a¹, and the other end having a loose bearing on the main cross shaft k.
The other end of the pin c², works in the groove e2, of a cam wheel ƒ³, keyed on
the main shaft k. The lower end of the lever 62, is jointed to a rod g², which is
jointed to a rod h2, working in a bearing 2, bolted to the horizontal cross bar w',.
This rod is provided with a spiral spring 2, one end of which bears on the
bearing 2, and the other end on a collar C formed on the rod h2; this spring is
for assisting to carry the card frame k', back to its starting point as each card
is punched, the front end of the rod being fastened to the card frame k¹; k³, is.
the perforated die plate bolted to the front of the frame a; immediately above
is what is called the stock plate 12, with corresponding perforations and holding
the row of punches o²; above the stock plate 12, is the punching plate m², below
which is a row of sliding levers nº, having parts of their surfaces cut away on
their underside at E and E', these levers corresponding in number with the
punches o2; 92, are cords or chains fastened to the levers n², and passing round
pulleys, at the rear end of the same and connected with the indices or pointers n;
the said cords or chains as shewn in figure 5, pass over the pulleys f³, in the
pointers n, and are attached to a spring rod g³, sliding within the pointers n; the
cords or chains 92, serve to draw backwards the punching levers n², for the purpose
"hereinafter described, the spring carrying the rod g³, back so as to slacken the

page_text: cords or chains q², when it is released; 83, are springs which cause the punching
plate m³, and punches o³, to return to their norinal position after each motion of
the treadle; the bolts 2, t2, are fixed to the punching plate m², and pass through
the die plate k², the lower ends being jointed to the rod or bar t¹, on the levers q¹,
as herein before described. On the shaft j', works an oscillating double crank u², v²;
the top crank u, fits accurately along the whole line of punching levers n³, and
serves to return them to their normal position after each punching operation in the
following manner:-the lower crank, is forced backwards at the return of the
treadle by a triangular shaped frame x³, bolted at its base to each side of the
treadle, which frame presses against a spring tongue w², fitted on the crank v³,
and forces the crank us, against the punching levers n²; the spring tongue w³,
works on a joint at F, which allows the tongue to give way and the frame x³, to
pass it when the treadle is depressed but to remain rigid when the frame x², meets
it on the upward movement of the treadle.
I can effect the regulation and adjustment of the pointers n, laterally in the
following manner reference being had to figure 6, sheet 1.
>
I form each of the pointers hollow and with a slot y³, on each side throughout
nearly its entire length; the centre pointer is fixed to the index frame; within the
other pointers slide two short rods a³, to each of which is jointed a rod b³, the
other ends of the rods 63, being jointed at to the end of the next pointer; the
centre pointer receives the ends of the rods 63, of the pointers on both sides as
shewn, the sliding rods a³, are each provided with a hole d³, through which holes
are passed rods e³, capable of being moved towards or away from each other by
any suitable means such as by right and left handed screws at their ends
The operation of the improved self acting reader is as follows:-
Supposing it be required to read in a pattern or design of which figure 7,
sheet 2, represents a portion or section, the said pattern or design is stretched on
the rollers A, A1, A2, in the usual manner with the first row X, of the pattern in à
line with the points of the pointers n, as shewn at figure 8, sheet 2; the
projection, on the grooved wheel r, is adjusted by means of the nut 8, and
screw t, so as to regulate the travel of the pattern on the rollers according to the
scale of the divisions of the pattern paper; the pointers n, are then adjusted
laterally to the scale of the divisions of the pattern so as to point to the first small
square of each division of the pattern as shewn in figure 8, sheet 2, so that the
first pointer points to the first small square and the second pointer points to the
thirteenth small square and so on for the whole width of the pattern; this lateral
adjustment of the pointers is effected by means of the right and left handed screws
at the ends of the rods es, which will be caused to approach or move away from
each other according to the direction in which the screws are turned; the rods a³,
sliding in the pointers n, will thus by means of the rods 68, draw the pointers
towards or away from each other, and the pointers when thus set will remain
rigidly in position and equidistant from each other. The card to be punched
is then placed as usual on the card plate k'. Assuming that all the squares on the
first row X of the pattern are of the particular colour to be read in, the cords q',
connected with the pointers 2 and 3 figure 8, are slightly pulled by the operator
and this operation is of course repeated in respect of the pointers of the corre-
sponding squares throughout the whole width of the pattern; on the cords q².
being pulled the corresponding levers or slides n², will be drawn by the cords q².
from the position shewn in full line figure 10, sheet 2, to that shewn in dotted
lines and the cut away parts E¹, of the levers or slides n³, will be moved from
over the punches into position for forcing their punches through the card; the
treadle m', being now depressed, the bar t¹, will be lowered by means of the
levers o', p³, and q', and will draw down the rods or bolts t2, and with them the
punching plate m³, which pressing on all of the levers n², will cause such of the
said levers as have been drawn backwards by the cords q³, as hereinbefore described
into the position shewn in full lines figure 11, sheet 2, to force their respective
punches through the card, the remaining levers or slides n³, in descending will

page_text: bring their cut away parts E', down over their respective punches as shewn in
dotted lines figure 11, sheet 2, and these punches will therefore not be subjected
to the pressure of the levers n²; the cut away parts E, limit the sliding movement
of the levers n³.
By the hereinbefore described arrangement of cords and pulleys connecting the
pointers with the punching levers I avoid the necessity of the operator having to
turn his eyes from the pointers to the corresponding keys which has hitherto been
the cause of frequent mistakes and consequent waste of the cards thus spoiled and
loss of time. The treadle in being depressed will by means of the rods ', and h³,
and lever i', have raised the plate 6', and with it the weighted pawl d', which will
thereby have been raised out of the teeth of the ratchet wheel a¹; the plate 6'; in
rising will raise the tooth or projection g', also out of the teeth of the ratchet
wheel a', by the pin c¹, which passes under and raises the spring catch f¹, carrying
the tooth gl; the treadle being now released from the pressure of the foot, the
punching plate m², slides n², and punches o³, will by means of the springs s²,
resume their former position, and the first small squares of the colour to be read in
will be found to be indicated by the first line of perforations in the card figure 9,
sheet 2, the perforations being repeated as shewn for each portion or section of the
pattern; in the drawing the corresponding squares and perforations on the pattern
and card respectively are indicated by corresponding figures; the treadle in rising
will draw down the pawl d', and thus rotate the ratchet wheel a¹, to the extent of
one tooth; the main shaft k, being thus rotated to a corresponding extent will
partially rotate the helical cam wheel j, the groove of which will operate the
slotted lever h, and the horizontal bar m, carrying the pointers n, so as to move
the pointers one single square of the pattern from right to left as hitherto. The
main shaft k, in rotating also carries with it the cam wheel f2, which by means of
the pin c², working in the groove of the same and in the slot in the plate d²,
operates the lever 6³, so as to cause its tail end, by means of the rods g², and h²,
to draw the card frame k', backwards to the required extent after the row of
perforations has been punched in the card. The treadle in rising carries the
frame 2, against the spring tongue w³, on the double crank u², v², and presses the
levers n³, back to their original position. The cords q2, attached to the pointers 2,
throughout the width of the pattern are then pulled and the treadle being again
depressed the second row of perforations marked 7, in figure 9, sheet 2, and
corresponding with the second small squares marked 7 on the pattern, figures 7
and 8 sheet 2, will be made in the card figure 9, and so on until the rest of the
row of the pattern has been read in when the card will have been perforated as
shewn in figure 9. When the perforation of one card has been completed and the
whole of the squares of the same colour in the first row read in, the pointers n, are
brought back to their starting position by the sliding piece o, in the helical cam
wheel j, (into one end of the groove of which sliding piece the pin i, will have
entered as shewn by dotted lines in figure 1, of the drawing) coming in contact
with the pin p', as the helical cam wheel j, revolves, whereby the sliding piece o,
is pushed into a position such that the other end of the groove therein shall meet
the helical groove in the wheel j, into which, as the operation of the machine
continues the pin i, will then pass carrying with it the slotted lever h; the pin p,
as the wheel j, continues to rotate then pushes back the sliding piece o, into its
forner position. The card frame having now been drawn back to its full extent
during one revolution of the main shaft k, it is returned to its starting point by
the pin c, on the lever 62, travelling through the straight portion of the groove e²,
in the cam wheel f2, the backward motion of the lever b³, being assisted by means of
the spring on the rod h². The pattern is moved forward on the rollers A, and A¹, to the
extent of one line of squares by the projection r¹, on the grooved wheel r, coming
against and moving the lever u, outwards from the wheel r,; this motion operates the
pawls w, by means of the rods x, and y, and the toothed wheels z, z¹, z², and rollers
A and A¹, are rotated to the required extent. The perforated card is now with-
drawn from the card frame, and a fresh card fixed therein, The squares in the

page_text: second row of a like colour to that of the squares of the first row which have just
been read in are next read in and so on until all the rows have been read in one
card representing one row of squares of one colour of the pattern; when all the
rows of the pattern of the one colour have been read in, another colour in the
pattern is read in in a similar manner to that hereinbefore described and so on
until the whole of the pattern has been read in; 11 and 12, figure 9 indicate the
lace holes in the card and 13 and 14 represent the stud holes.
Having thus described my invention and the manner of performing the same
what I claim is :-
Firstly. The combination of parts forming the improved self acting reader for
the Jacquard arranged and operating substantially as and for the purposes
herein before described and represented in the accompanying Drawings.
Secondly. In a self acting reader for the Jacquard the method of connecting the
pointers and punching levers by the employment of cords and pullies or their
equivalents substantially as and for the purposes herein before described and
represented in figures 2, 3, 4 and 5, sheet 1, and figures 10 and 11 sheet 2, of the
accompanying drawings.
Thirdly. The method of effecting the adjustment of the pointers by the
employment of the combination of hollow rods and levers and bars as and for
the purposes herein before described and represented in figure 6 sheet 1 of the
accompanying drawings.
Fourthly. The method of adjusting the motion of the toothed wheels carrying
the rollers by the employment of a grooved wheel provided with an adjustable
projection as and for the purposes herein before described and represented in sheet 1
of the accompanying drawings.
Fifthly. The combination with the helical cam j, of the sliding piece o, and pins
P, P, arranged and operating substantially as and for the purpose hereinbefore
described and represented in sheet 1 of the accompanying drawings.
Sixthly. The method of drawing out the card frame and returning it to its
starting position by the employment of a grooved cam wheel in combination with
a slotted lever having a fulcrum capable of adjustment and a spiral spring
substantially as hereinbefore described and represented in sheet 1 of the
accompanying drawings.
In witness whereof I the said Robert Wolfe Sutleffe have hereto set my hand
and seal this seventh day of November in the year of our Lord one thousand
eight hundred and eighty three.
