I JAMES MCMURDO of New Street Miles Platting Manchester in the County of
Lancaster Machinist do hereby declare the nature of my invention for "IMPROVE-
MENTS IN THE CONSTRUCTION OF PUNCHING MACHINES FOR REPEATING JACQUARD
PATTERN CARDS "to be as follows:-
My invention relates to that class of machines for above purpose known as
Devoge's" repeating machine and consists principally in so mounting the punches
of such machines that they are carried in a sliding frame together with the keys
and the locking comb and this sliding frame moves up and down to the cards
which pass over a stationary punching plate, instead of forcing the cards to be
punched against stationary punches.
My improved repeating machine is constructed as follows:-
Beneath a stationary punch-plate secured steadily and firmly to the frame of the
machine I mount a shaft driven by any suitable means; and upon either side of
this shaft just outside the frame I mount an excentric connected by a rod to either
end of a sliding frame which carries the punches, the keys which steady them
in the frame, and the comb which locks them either up or down as hereafter
described.
These excentrics lower this frame when the punches are required to cut the card
and raise it again when this has been performed ready for the next card to be
brought on to the punch plate.
The jacquard machine is mounted immediately above the punches and each hook
thereof is connected to one of the said punches by a pair of wires each formed with
an eye at the end through which its corresponding wire slides and a spiral spring
being fitted round one of the wires between the eyes forms an elastic connection
between the Jacquard and the punch.
The locking comb itself is constructed as usual in that class of machine known
as Devoge's repeating machine but the rods upon which it slides are held in position
by spiral springs and are actuated by oscillating levers which are provided with
slots to admit of the up and down motion of the frame which carries the said comb
and the punches. These levers are bell cranked and are worked by cams on the

page_text: before mentioned shaft. The excentric or crank which actuates the "griffe" and
cylinder of the Jacquard machine is also mounted on this shaft.
The action of my apparatus is as follows:-
The Jacquard hooks which are lifted by the griffe of the machine (by blanks
being presented to the needles) raise their corresponding punches and these are
locked in this position and the other punches are locked in their position by the
comb as usual in machines of the above mentioned type. The excentrics on the
shaft above named then draw down the punches to the card which is upon
the fixed punch plate beneath. The raised punches make no impression on the
card, but the others punch holes therein, and as there are as many rows of punches
as there are rows of holes on the cards to be repeated a whole card is punched at
one revolution of the shaft.
The excentrics then raise the punches from the card, a fresh card is substituted
therefor and the oscillating levers move out the comb and unlock the punches
ready to be acted upon by the next lift of the "griffe" and the punching proceeds
as before described.

page_text: Improvements in the Construction of Punching Machines for
Repeating Jacquard Pattern Cards.
I JAMES MCMURDO of New Street, Miles Platting Manchester in the County of
Lancaster Machinist, do hereby declare the nature of my invention for IMPROVE-
MENTS IN THE CONSTRUCTION OF PUNCHING MACHINES FOR REPEATING JACQUARD
PATTERN-CARDS and in what manner the same is to be performed, to be particularly
described and ascertained in and by. the following statement:—
My invention relates to that class of machines for the above purpose known as
Devoge's repeating machine and consists principally in so mounting the punches of
such machines that they are carried in a sliding frame together with the keys and
the locking comb, and this sliding frame moves up and down to the cards which
pass over a stationary punching plate, instead of forcing the card to be punched
against stationary punches.
The nature and object of my said invention will be readily understood on
reference to the annexed two sheets of drawings marked with figures and letters
of reference corresponding with those in the following explanation thereof.
On Sheet 1. Fig. 1. is an elevation of my improved repeating machine with the
card cylinder removed. Fig. 2 is a section of the working parts of the same drawn
to a larger scale and Fig. 3. shows one of the punches and its connection to the
Jacquard needle as hereafter described. On Sheet 2 the figure shows a general
perspective view of the repeating machine and the Jacquard machine above it.
My improved repeating machine is constructed as follows:-
Beneath a stationary punch-plate a, a secured steadily and firmly to the frame b, b
of the machine mount a shaft driven by any suitable means: such as the
pulleys d, and spur gearing e, e and upon either side of this shaft c, c just outside
the frame b, b I mount an excentric f, fx connected by a rod g, g¹ to either end of
a sliding frame h, h which carries the punches a¹, a¹ the keys i, i which steady
them in the frame and the comb k, k which locks them either up or down as here-
after described.
These excentrics f, fx lower this frame h, h when the punches a¹, a' are required
to cut the card and raise it again when this has been performed ready for the next
card to be brought on to the punch plate.
The cards pass over the cylinders 1, one of which is actuated by suitable means
for changing the said cards. The drawing shews the cylinder actuated by the
book, lever, sliding spring bolt 14, and cam m on the shaft c, c.
The Jacquard machine is mounted immediately above the punches (sce sheet 2)
and each hook thereof is connected to one of the said punches a', a' by a pair of
wires a² and a³, each formed with an eye at the end through which its corre-
sponding wire slides and a spiral spring a being fitted round one of the wires
between the eyes, forms a spring connection between the Jacquard book and the
punch a which will not become slack (see Fig. 3. sheet 1)
The locking comb k, k itself is constructed as usual in that class of machine
known as Devoge's repeating machine but the rods k, k¹ upon which it slides are

page_text: held in position by spiral springs and are actuated by oscillating levers n, n which
are provided with slots to admit of the up and down motion of the frame h, h
which carries the said comb k, k and the punches a¹, a¹ these levers n n are bell-
cranked and are worked by cams m, m on the before mentioned shaft c, c The
excentric or crank o, o which actuates the "griffe" and cylinder of the Jacquard
machine by means of the rod p, p is also mounted on this shaft c, c.
The action of my apparatus is as follows:-
The Jacquard hooks which are lifted by the "griffe" of the machine (by blanks
being presented to the needles) raise their corresponding punches a¹, a¹ and these
are locked in this position and the other punches are locked in their position
by the comb k, as usual in machines of the above mentioned type. The
excentrics fx on the shaft c, c above named then draw down the punches a¹, a¹
to the card which is upon the fixed punch plate a, a. The raised punches make no
impression on the card but the others punch holes therein, and as there are as
many rows of punches as there are rows of holes on the cards to be repeated a whole
card is punched at one revolution of the shaft c, c.
The excentrics f, fx then raise the punches a' a' from the card, a fresh card is
substituted therefor and the oscillating levers n, n move out the comb k, k and
unlock the punches a¹, a¹ ready to be acted upon by the next lift of the "griffe "
and the punching proceeds as before described.
By using smaller cylinders 1, and tying up the outside rows of punches on
either side of the frame narrower cards may be cut, as shown at Fig. 2; thus if
two rows of 50 on either side of a "six hundred repeating machine," is tied up the
machine will repeat cards for a four hundred Jacquard machine.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
First. The improved repeating machine constructed and operating as herein-
before described and illustrated by the drawing annexed.
Secondly. The sliding frame carrying the comb, the keys and the punches, and
actuated substantially as and for the purposes hereinbefore described.
Thirdly. The combination of the sliding frame, the comb keys and punches with
a fixed stationary punch plate (over which the cards pass and upon which they are
perforated) substantially as hereinbefore described and illustrated by the drawing
annexed.
Fourthly. The improved spring connection between the Jacquard needles and
the punches, substantially as hereinbefore described and illustrated by the
drawings annexed.
