PROVISIONAL SPECIFICATION.
Improved Mechanism applicable to the Card or Pattern Cylinder
of Circular Box Looms.
PAUL HEY HARTLEY Bridge Street Colne, Lancashire Weaving Overlooker
do hereby declare the nature of this invention to be as follows:-
To apply mechanism to drive the card or pattern cylinder of circular box looms,
at a variable number of picks per card. This is accomplished, by using two
catches and two kinds of cards on the same cylinder, one of the two kinds of cards,
which I call lump cards have a projection on, and the other, which I call plain
cards are without projection, the latter represent two picks each card, while the
former represent any even number of picks required. When the plain cards are
in action, one of the catches, which I call A moves the cylinder every two picks,
while the other catch A¹ (which is attached to a lever resting on a card of a second
cylinder) is held too high to engage with the peg wheel. This continues until the
Jump cards come in contact with a piece resting on the cylinder which they lift up.
This action prevents the catch A from engaging with the cylinder, at the same
time it releases a catch I call B which moves the second cylinder (this second
cylinder only moves when the lump cards are in contact with the piece mentioned
above) and on which a number of cards are placed this number varies as it suits
the pattern, but it is fixed when once the cards are put on, one or more of these
cards have a hole in and when this hole arrives on the top of the cylinder, the
lever carrying the catch A' falls a little lower so that the catch A¹ engages
with the cylinder carrying the two kinds of cards and moves it one card. This is
repeated as many times as there are lump cards succeeding each other, when again
the plain cards come in contact with the cylinder, the catch A is released
and the catches B and A¹ are again out of action. By these means a large saving
of cards is obtained without the aid of a third cylinder.

PAUL HEY HARTLEY Bridge Street, Colne in the County of Lancaster
Overlooker 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 :-―
To apply mechanism to drive the card or pattern cylinder of circular box-looms
at a variable number of picks per card..
This is accomplished by using two catches and two kinds of cards on the same
cylinder, one of the two kinds of cards which I call lump cards, have a projection
on, and the other which I call plain (or those commonly used) are without projection.
The latter when in action represent two picks each card, while the former
represent any even number of picks required.

page_text: In the accompanying drawings Figures 1, 2, 3, 4, 5, 6, 7, and 8 are detached
views of the principle parts of my apparatus, for driving the card cylinder of
circular box looms, at a variable number of picks for each card.
..
Figs. 1, 2 and 3 shows plan, end and front elevation of the lever rest C having
its centre at C¹ and also a slot at C, it is kept in the position shown by means of a
spring C3 and the bracket F.
Figs. 4, 5 and 6 shows plan, end and front elevation of the cranked lever D and
cylinder A this cylinder has a ratchet or peg wheel at each end.
The lever D has its centre D', the vertical end D2 is made to pass. through the
slot C2 of the rest C mentioned above, while the horizontal end D³ lies on the top
of the cylinder A, in this position the cylinder A is moved in the ordinary manner
and each card represents two picks.
Figs. 7 and 8 shows plan and end elevation of the lever which carries the catch A*
this lever rests on a card on the cylinder B, seen in Figs. 9, 10-and-12, the catch-A²
is used to move the cylinder A when lump cards are present, and it can only do so
when a card with a bole in the middle. allows the lever to fall a little lower so that
the catch A engages with the peg-wheel of cylinder A.
Figs. 9, 10, 11 (Fig. 11 is a sectional elevation on the line y of Fig. 9) and 12
shows the apparatus applied to the parts of circular box mechanism most concerned,
the motion and use of which, being well understood is not further described.
The rest C is placed under the Lor checking levers, two of which namely those
carrying the catches A¹, B' have a pin E or like projection.
The pin E on the lever B is upon the rest C and the catch B' is held too high
to engage with the peg wheel of the cylinder B (seen in Fig. 9).
The pin E on the lever A³ (Fig. 11) passes clear of the rest C thus allowing
the catch A' to move the cylinder A in the ordinary mauner mentioned above,
untill a lump card arrives on the top of cylinder A lifting the end D³ of the
lever D while the end D2 moves the rest Ċ under the pin E of the lever 'A*
and away from the pin E of the lever B2, the catch A¹ is now held too high to
engage with its peg wheel, while the pin E of the lever B2 passes clear of the
rest C and allows the catch B¹ to move the cylinder B at the rate of two picks
each card, when a card with a hole in the middle (seen Fig. 12) arrives at the
top, thus allowing the lever carrying the catch A to fall a little lower, so that
the catch A engages with its peg wheel and moves the cylinder A one card the
number of picks the cylinder B has moved is represented by one lump card, if
the cylinder B continues to move there must be another lump card on the top
of cylinder A that is two lump cards together each representing the number of
picks between the cards having a hole in the middle, the number of cards between
those with a hole in can be varied at will, therefore the lump card represents a
variable number of picks, when again a plain card is present on the top of
cylinder A the rest C moves to its original position and cylinder B is stopped.
Having now particularly described and ascertained the nature of my said inven-
tioned; and in what manner the same is to be performed, I declare that what
claim is
1st. The employment of two kinds of cards in the same pattern chain. the
number of picks represented by one kind being variable, substantially as
described.
2nd. The application of mechanism to drive the card cylinder at a variable
number of picks each card substantially as described and illustrated.
