and Punching Patterns in Jacquard Garus.
We WILLIAM MARTIN and WILLIAM TRUSWELL MARTIN of Russell Street in the
Town of Nottingham Machinists do hereby declare the nature of our said invention
to be as follows:-
This invention consists of a perforated block and slays filled horizontally with
selecting keys and vertically with punches. Below these punches we have a bed with
a pair of perforated punch plates, working up and down in perpendicular fashion
these punch plates being grooved so as to allow cards to pass between them are fed
from a bottomless box containing blank cards by means of endless bands studded the
exact width of the cards required to be punched, and travelling under the bottomless
Box and between the punch plates and drawing the bottom card out of the box with
each motion of the machine by means of an arrangement of Racking apparatus.
When the card is between the punch plates the bed containing the plates rises with
the bands and forces the card against the bottom of the punches which perforates the
card, except where the selecting keys are drawn back as in the ordinary way of
selecting by what is known in the trade as a changing roller which allows the punches
to rise with instead of cutting through the card. After the card is punched the bed
and plates and bands descend and the same motion which takes the blank card into
the plates brings the punched card out of the plates and propels it down a slope into
another box fixed for the purpose.
This invention applies more particularly to the punching of cards for the manu-
facture of lace curtains but may be employed for any other machines where a Jacquard
is used.

We WILLIAM MARTIN and WILLIAM TRUSWELL MARTIN of Russell Street in the
Town of Nottingham Machinists, do hereby declare the nature of our said invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
In carrying out our Invention, we use a bed with a pair of perforated punch plates,
which work up and down by means of eccentrics and connections from a shaft, geared
with the main driving shaft of the Machine. The punch plates are grooved, so as to
allow the cards to pass between them; and the cards are fed from a bottomless hox
containing blank cards, by means of endless bands. These bands are studded the
exact width of the cards required to be punched, and they travel by means of an
arrangement of rocking apparatus, under the bottomless box, and between the punch
plates, drawing the bottom card out of the box and carrying it between the punch
plates upon each motion of the Machine. Above the bed we have a Block, per-
forated horizontally for the selecting keys, and vertically for the punches; and
fitted with perforated slays, which, together with the Block, carry the Selecting
Keys and punches. On each Key is a spring, which returns the key into its proper
position, after being drawn back by the string in the ordinary way, for the purposes
of selecting. When the bed containing the punch plates is at its lowest point, the
bands travel the width of one card, but do not travel while the bed and plates ascend,
thus lifting the card to the punches, which, being held in their proper position by the
Selecting Keys, perforate the card, except where the keys are drawn back, as in
the ordinary method of selecting the pattern, by what is known in the trade as a
changing-roller, which allows the punches to rise with, instead of cutting through the
card. When the card is punched, the bed with the plates and bands, descend, and
the same motion which takes the blank card into the plates, brings the punched card
out of the plates, and propels it down a slope, into a box fixed for the purpose.―The
arrangement of rocking apparatus, before mentioned, consists of a ratchet wheel and
clawker, with a connection lever and spring worked from a cam on the eccentric shaft
of the Machine. In the ordinary method of selecting and punching patterns in
Jacquard Cards, two Machines are used, one for selecting the punches, according to
the pattern, after being read on the ordinary reading machine; and the other for
pressing the punches, after being taken from the Selecting Machine, through the
Card. Two persons are required to work the two Machines, but with the use of
the improvements in our Invention, only one person is required to select the keys,
which operate on the punches in the manner described.
And in order that our said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.

A pinion u, on the shaft d, drives the wheel v, which is fast on the shaft c. At each
end of the shaft can eccentric b is fitted. The rods 61 61 of the eccentrics sustain the
reciprocating bed i, and work the same up and down. The bed i carries a pair of
perforated punch plates a a, which travel with the bed. The punch plates à a are
grooved, so as to allow the bands 9 9 carrying cards to pass between them. The
blank cards p are fed from the bottomless box f, from whence they successively fall
upon the endless bands 9 g, carried by wheels g¹ g³. The bands g g are studded to the
exact width of the cards. A is a lever, pivotted at h¹, and fitted with an anti friction
roller y, which is kept in contact with the camt by the spring z. The lever h is
pivotted to a link h³, and this link is pivotted to a short link oscillating on the shaft
of the wheel g. The clawker or pawl h³ actuates the ratchet wheel q, fast on its
shaft, intermittently. This rocking apparatus, h h³ h³ h*, causes the bands g to carry
the bottom card e from the box f between the punch plates a a. Above the bed i is
placed a block j, perforated horizontally for the selecting keys k, and vertically for the
punches 1. m m are perforated slays which, together with the block j, carry the
selecting keys k and punches 1. On each of the keys ka spiral spring u is fitted
which returns the keys to their normal position, after being drawn back by the strings o,
in the ordinary way for the purpose of selecting. When the bed i, carrying the
punch plates a a, is at its lowest position, the bands g g travel the width of one card
but cease travelling while the bed i and plates a a ascend, thus lifting the card e to the
punches 1, which punches are held in their proper position by the selecting keys k, and
perforate the card, except such punches the keys of which are drawn back by the
strings o, as in the ordinary method of selecting the pattern by what is known in the
trade as a changing roller; our arrangement allowing the punches to rise with,
instead of cutting through the card e. When the card e is punched, the bed i with
the plates a a and bands g g descend, and the same motion which carries the blank
cards between the plates a a carries the punched cards away into the box & by means
of the guide r.

Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The improved method of fitting the Selecting Keys k and thereby causing the
same to operate upon the punches / substantially as hereinbefore described, and shewn
on the drawings.
2. The improved method of lifting the cards p to the punches instead of lowering
the punches to the cards; the block j which carries the punches being a fixture;
substantially as hereinbefore described and shewn on the drawings.
3. The improved method of, and automatic apparatus for, feeding the punch plates a a
with blank cards, and delivering them from the plates a a when punched, substantially
as hereinbefore described and shewn on the drawings.
4. The general arrangement, construction and combination of apparatus, constituting
our invention of a Machine for the combined and more speedy process of selecting
and punching patterns substantially as hereinbefore described and shown on the
drawings.
