page_text: We JAMES CRABTREE Manager and JIM BREARLEY Mechanic both of Croft Mills
Heckmondwike in the County of York do hereby declare the nature of the said
invention for "IMPROVEMENTS IN WORKING DROP BOXES OF LOOMS" to be as
follows:-
This invention relates to improved apparatus for indicating and securing the pick
of any particular shuttle in rising and falling box looms whether the order be pick.
and pick or skip shuttle according to the pattern being woven.
According to this invention secured to the end frame of the loom are brackets
carrying a cross shaft on which are stepped tappets or tappets of various sizes and
corresponding in number to the number of shuttles-Above and resting upon the
several tappets are vertical knives working through guides and having each a
projecting catch piece or shoulder-each knife is clipped by a "needle" acted upon
by card or pattern mechanism operated by crank motion from the cross shaft
referred to.
The action is as follows:-
As the tappets revolve they raise the knives whereon the card or other pattern
mechanism will act upon the ends of the needles and push back such of the knives
as are not required to act for change of box and shuttle-but when there is a hole.
in the card opposite the end of a needle the latter not being forced back and on its
being raised by its tappet the notch referred to engages with and lifts one of a pair
of levers one end of which hinges upon a stud the other ends being connected by
rods and cranks with the swivel or other motion of the notched or stepped shuttle:
box levers at opposite ends of the loom.

Mills, Heckmondwike, in the County of York do hereby declare the nature of
the said invention for "IMPROVEMENTS IN WORKING DROP BOXES OF LOOMS and
in what manner the same is to be performed; to be particularly described and
ascertained in and by the following statement aided by the annexed drawings:-
This invention relates, to improved apparatus for indicating, and securing the
pick, of any particular shuttle, in rising and falling box looms, whether the order.
be, pick and pick, or skip shuttle, according to the pattern being woven.
Such being the nature, and object of the said invention, the following is a
complete description of same, reference being had, to the accompanying drawings, 1
forming a part of this specification, in which :-
Fig. 1 is a side elevation of improved apparatus.
Fig. 2 is an end elevation of Fig. 1.
Fig. 3 is a vertical section through A. B. Fig. 2.
At 1 is the end frame of the loom. 2. 2 are brackets, carrying the cross shaft 8. 1
on which are the stepped tappets 4. 4, varying in size, and corresponding in
number, to the number of shuttle cells and shuttles-At 5. 5, are vertical knives,
working through the guides 6. 6. each knife 5. has a notch or catch pièce 7. formed
therein At 8 is a needle, through the eye 9. of which the knife 5. passes, and
works, as raised and lowered, by the tappet 4-At 10 is the card cylinder, operated
by bell crank 11, and the strap eccentric 12, from the cross shaft 3, the latter
receives its motion from the ordinary crank shaft of the loom through the gear
wheels 13-14-15 and 16.
The Action is as follows:-
'As the tappets 4 revolve, they raise the knives 5. the card or other pattern
mechanism 10, will act upon the ends of the needles 8, and push back such of the
knives 5, as are not required to act, for change of box and shuttle-but when there
is a hole in the card, opposite the end of a needle, the latter not being forced back,
and on its being raised, by its tappet 4. the notch 7 engages with, and lifts one of
a pair of levers 17, one end of which hinges upon a stud 18, the other ends being
connected by rods 19. and cranks 20. with the swivel, or other motion, of the
notched or stepped shuttle box levers, at opposite ends of the loom, as ordinary and
well understood.
Having now particularly described, and ascertained the nature of the said
invention, and in what manner the same is to be performed, We declare that what :
we claim is:-
The stepped tappets 4, notched knives 5, needles 8, and levers 17, in combination,
and for purpose herein described.
