Improve Jacquard Card
I FRANK WILKINSON of Beeston Hall, Beeston, Nottinghamshire Lace
Manufacturer do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 show a left end view and a back view of the jacquard card
punching apparatus drawn one eighth the full size.
Figure 3 a half plan of portion of the upper parts drawn one quarter the
full size.
Figure 4 a vertical sectional view of the same parts one half the full size.
Figure 5 shows a side view of the bevel toothed gearing employed, and certain
cams, levers, and connecting links, drawn one quarter the full size.
The punching apparatus consists of two outer standards 1 (shown at Figures 1
and 2) supporting a shaft 1 provided with a fast and loose pulley and two
fly wheels 1. The shaft 1 carries a clutch boss 1 thrown into or out of connection
with a wheel 1° (partly shown in side view at Figure 5) by a rocking lever 1
traversed by a right angled lever 1', hinged to a rod 15 rocked by a handle
conveniently placed.
The shaft 1 is also supported by bearings at the front of a pair of standards 2
placed between the standards The standards 2 form bearings for a shaft 2
having a wheel 2° fast on it driven by the wheel 14. Each end of shaft 2" has an
eccentric 2° fitted on it, the rods 2ª of the eccentrics sustain a reciprocating bed 3
and move it up and down. The bed 3 carries a pair of vertically perforated punch
plates 3 3 (shown at Figure 4) between which the card 3d to be punched lies.
Above the bed 3 is a fixed bed 4 supported at each end by the standards 2, this
bed is formed of two end pieces 4, a bottom horizontal piece 4* an upper vertical
piece 4° and an intermediate piece 4" "the whole forming one casting" the piece 4°
is set at an angle and provided with two clamping screws 4 one of which is shown
in plan at Figure 3, and in section at Figure 4.
The ends of the fixed bed are slightly recessed on the inner side to receive the
ends of a sley box 5, from each recess a block 4° projects and enters a slot cut in
the ends of the sley box, "the block is shown by dotted lines only.'
"
To the underside of the vertical piece 4 of the fixed bed four brackets 4' are
secured, their lower ends carry the back edge of a vertically perforated plate 48, the
front edge of the plate is secured to the underside of the horizontal piece 4**.
Above the plate 48 an angular plate 4 is secured to the ends of the fixed bed, this
plate is perforated vertically, the perforations in it and the three plates 4º 3º and 3ª
being in line.
The four plates support the required number of rows of punches 3°, two of which
a short one and a long one are shown the full size at Figure 6.
The punches are prevented from falling through the plates by being made
somewhat thicker above the plate 48. The sley box forms an angular sley plate 5ª
at its back end, and a vertical sley plate 5° in front of it, the front end of the box
carries a vertical sley plate 5°, the three plates are perforated horizontally. In
the perforations horizontal selecting needles 5ª slide, the front end of each needle
forms a spring hook upon which the back looped end of a string 4ª of a suitable
selecting machine may be hooked.
In front of the sley 5 each needle is provided with a collar, between the collar

page_text: each needle has a spring
"
not shown in the drawings" coiled round
""
and the sley
it in the usual way.
The springs pressing upon the collars and the back of the sley 5 hold the
needles in the position shown at Figure 4 with the back end of each needle
protruding through the sley 5° and lying over the tops of the punches 3 beneath
them prevent them from rising. The lower ends of the punches cutting through the
card 3 as the bed 3 and punch plates 3ª 3b rise, except when the back end of any
selecting needle is drawn away from the top of its punch by the string 4 the punch
then rises with the card instead of cutting through it.
From each side of the sley box 5 near the front end two arms project which slide
upon a rod 4' secured to the front of the bed 4. The front ends of the rods carry a
vertical sley plate 5' held by a set screw at each end, through this sley the
strings 4* pass.
Before hooking the strings on the needles, the sley 5' is released, moved
backwards, and passed over the spring hooks of the needles, then when all the
strings have been hooked on them, the sley is moved towards the front and secured
in the position shown at Figure 3.
Beneath the front of the sley box a plate is secured, provided at its centre with
a screw threaded nut carrying a screw 58 grooved at its back end, and turning in a
slotted bearing plate 5 secured to the front of the fixed bed. When the clamping
screws 4ª are unscrewed the sley box with its selecting needles and springs may be
moved away from the punches by the screw 58 when a punch is broken to insert a new
one, or when a fresh selection of strings have to be hooked on the selecting needles.
After the sley box with its needles have been returned to the position shown
at Figures 3 and 4 upon the clamping screws being turned down they will be held
fast while the cards are being punched.
The blank cards 3d are placed between a pair of grooved bottomless arms 6
(shown at Figures 1 and 2) capable of adjustment to or from each other "according
to the length of card to be punched on a plate 6 supported by four brackets
23
carried by the back of the moveable bed 3.
The card to be punched is placed between the punch plates 3* 3b by the following
means (shown at Figures 1 and and in side view at Figure 5). From the back
of the moveable bed two rods project on which the ends of a bar 6" slide, on the
top of the bar two or more thin plates 6 are capable of adjustment to or from each
other. The front ends of the plates lie on the back edge of the plate 6ª, the bar 65
and the plates 6° are moved backwards and forwards by the upper slotted ends of
two levers 6d engaging with studs carried by the bar 6b, the lower ends of the levers
are secured on a shaft 6° rocking in bearings secured to the back of the moveable
bed. The shaft carries a lever connected by a link to the upper end of a lever 7,
the lower end rocking upon an axle fixed to a cross bar 7*, secured to the
standards 2.
The lever 7 carries a truck operated by a cam 8 on the shaft 2, the bar 6b has
two chains each passed over a pulley 8d and attached to the upper end of a coiled
spring, the lower end of each spring being hooked to a tie rod at the back of the
standards 2.
The springs hold the truck lever 7 up to the cam 8 causing the plates 6° to push
the bottom card from beneath the grooved arms 6 into its right position between
the punch plates 3 3b to be punched, the cam then forces the lever 7 towards the
front, to move the plates 6° backward ready to push forward the next card to be
punched. The punched cards fall into a box 8 secured to the front of the movable
bed. The shaft 2ª also carries two cams 9 operating two truck bearing levers 7b
for connecting the punching machine with a suitable selecting machine.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that 'what"
I claim is :-
