Improvements in "Drop Box" and "Pick and Pick" Looms
for Weaving.
I, MILES SOWDEN of the firm of D. Sowden and Sons, Machine Makers Shipley
near Bradford in the County of York do hereby declare the nature of this invention
to be as follows:-
This invention relates to drop box looms, and to pick and pick looms, and consists
of improved construction, combination, and arrangement of parts for effecting the
desired change of shuttle and locking the boxes in the position to which they have
been moved or set, and to improved mechanism for moving and controlling the picking
tappets when weaving by pick and pick.
According to the number of cells and shuttles in the drop box employed are a liko
number of levers free to work on a stud passed through the angle or elbow of the
levers, these are indicating levers, one end of each being operated by the card or
pattern mechanism, the end of the other arms acts on, upright catch rods, the lower
end of which is attached by a joint pin to horizontal levers having a fulcrum about
midway their length and on the other end of which levers are catch or notched push
and pull rods which as indicated by the pattern mechanism engage one or other side
of a disc having studs and as the disc is pulled and turned to the right or to the left
it gives motion to a gear or pinion wheel turning such wheel in one or the other
direction, and the latter being geared with a rack and slide carrying the shuttle boxes,
the latter will thus be lifted or dropt accordingley.
On the other or opposite face of the disc to that in which are the studs are wide
spaced angular teeth or lugs between two of which a corresponding angled top of a
cross head is received. The latter is for locking the disc wheels and boxes in position
until the shuttle has been picked and a change is required, and is kept up to the disc
and studs by means of a spiral or other spring.
When after stopping the loom on a misspick or for other reason it is necessary
to raise or depress the boxes by hand a treadle removes the cross head clear of
the disc.

page_text: The catch rods for operating the levers and other parts referred to receive their
motion from a rocking lever operated by tappet on the main shaft, a like rocking
lever and tappet and indicating mechanism and horizontal lever are connected with
the cross head locking device, so as to take off the latter whenever a change of box is
to be made.
For changing position of the tappets I employ at back of the loom a cross shaft,
on opposite ends are two circular tappets the inner rims facing each other and being
of form somewhat similar to a waved or corrugated line, the upper part of the curve
forces aside a projecting finger on which is a runner on a slide rod, the other end of
which is connected by cross finger with one slot of a Y shaped lever and pushes the
latter over on its fulcrum stud, a like arrangement of parts on the other side of
the Y lever operates a like slide rod and these are connected by fork clip with the
two tappets on opposite sides of the loom, so that as the circular tappets revolve,
their prominent and concave parts effect the requisite in and out movement of the
tappets from line of the picking cones.
When it is desirable after mispicks or from other cause to run or turn the loom
without the shuttle being picked a treadle lifts the Y lever on its stud and by a slot
formed in the lower limb of the Y both tappets are contracted and kept out of contact
with the picking cones.

Improvements in Drop Box and Pick and Pick Looms
for Weaving.
I MILES SOWDEN of the firm of D. Sowden & Sons, Machine Makers Shipley, near
Bradford in the County of York, 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:-
This Invention relates to drop box looms, and to pick and pick looms and consists
of improved construction, combination and arrangement of parts for effecting the
desired change of shuttle and locking the boxes in the position to which they have
been moved or set, and to improved mechanism for moving and controlling the picking
tappets when weaving by pick and pick.
Such being the nature and object of my said invention the following is a complete
description of same reference being had to the accompanying drawings forming a part
of this Specification in which :-
Fig. 1. is a side elevation of my improved appliances for operating the "drop box"
and apparatus for locking the same.
Fig. 2. is a front elevation of same.
Fig. 3. is a side elevation of apparatus for moving and controlling the picking
tappets when weaving with pick and pick looms.
Fig. 4. is a front elevation of Fig. 3.
According to the number of cells and shuttles in the drop box 1. employed are a
like number of L levers 2. 2. for raising the box and a like number for lowering the
same free to work on a stud 3 passed through the angle or elbow of the levers, 2. 2.
these are indicating levers one end 4. of each being operated by the Card or pattern
mechanism 5. the other end 6. of the arms or levers 2. 2. act on upright catch
rods 7. 7. the lower ends of which are attached by a joint pin to horizontal levers 8. S.
having a fulcrum 9 about midway their length, and on the other end of which levers
are catch or notched push and pull rods 10. 10. which as indicated by the pattern
inechanism 5. engage one or other side of a disc 11. having studs 12 and as the
disc 11 is pulled and turned to the right or to the left, it gives motion to a gear or
pinion wheel 13. turning such wheel in one or the other direction, and the latter being
geared with a rack 14. and slide carrying the shuttle boxes 1. the latter will then be
lifted or drop accordingly. On the same shaft as the disc 11. is a segment of a wheel
on which are wide spaced angular teeth 15. or lugs between two of which a
corresponding angled top of a cross head 16 is received.
The latter is for locking the disc 11. wheels 13. 16 and boxes 11 in position until
the shuttle has been picked and a change is required, and the crosshead 16 is kept
up to the disc 11. by means of a spiral or other spring 17. When after stopping the
loom on a mispick or for other reason, it is necessary to raise or depress the boxes 11.
by hand a treadle 18 removes the cross head 16 clear of the disc 11.

page_text: The catch rod 7. 7. for operating the levers and other parts referred to receive their
motion from a rocking lever 19. operated by tappet 20. on the main shaft, 21. a like
rocking lever 19 and tappet 20 and indicating mechanism and horizontal lever are
connected with the crosshead locking device 16. so as to take off the latter whenever
a change of box is to be made.
In pick and pick for changing position of the tappets 1. 2. (see Figs. 3 and 4) I
employ at back of the loom a cross shaft 3, on opposite ends are two circular
tappets 4. one at each end of the loom the inner rims 4 facing each other and
being of form somewhat similar to a waved or corrugated line, the higher parts 5
of the curve forces aside a projecting finger 5ª, on a cross rod 6 the other end of
which is connected by cross finger 7. with one slot 8 of a Y shaped lever 9. and
pushes the latter over on its fulcrum stud 10, a like arrangement of parts on the
other side of the Y lever 9 operates a like slide rod 6. and these are connected
by fork clip 11, with the two tappets 12. on opposite sides of the loom, so that
as the circular tappets 4. revolve their prominent and concave parts effect the
requisite in and out movement of the tappets 1. 2. from line of the picking cones.
When it is desirable after mispicks or from other cause to run or turn the loom
without the shutile being picked a treadle 13, lifts the Y lever 9 on its stud 10
and by a slot 14 formed in the lower limb of the Y both tappets are contracted
and kept out of contact with the picking cones. The cross shaft 3. receives its
motion from a disc 16. on which are studs 17. engaging with a pendant hooked
rod 18 operated by rocking lever 19 and tappet 20.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is
1. The levers 2 and 7, 8. and 10. operated by tappet 20 and lever 19 all in
combination for purpose herein described and as illustrated by annexed drawings.
2. The levers 2. 7. S. 10 operated by tappet 20 and lever 19 in combination with the
locking device 15. 16 operated as described and substantially as illustrated by annexed
drawings.
3. The tappets 4. 4. Fingers 5. 5. rods 6. 6. Y lever 9 all in combination, operated
and operating in manner and for purpose herein fully described and as illustrated by
drawings annexed.
