IMPROVEMENTS IN APPARATUS FOR OPERATING RISING AND FALLING BOXES OF LOOMS FOR WEAVING
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I ENOCH OPENSHAW TAYLOR of Marsden Iron Works, Marsden, in the County
of York Machine Maker and Ironfounder do hereby declare the nature of my said
invention for "IMPROVEMENTS IN APPARATUS FOR OPERATING RISING AND FALLING
BOXES OF LOOMS FOR WEAVING" to be as follows:-
This invention consists of an improved combination of mechanism for raising:
and lowering the multiple shuttle boxes so as to bring any shuttle and cell in line
with the shuttle race according to pattern being woven and change of shuttle
required.
For purpose aforesaid I employ a pinion, on the crank shaft, which gears with,
and drives another like wheel, on a stud, the latter carries a bevel wheel,.gearing
with a similar wheel, on a vertical shaft-this by means of intervening wheels, and
shaft, drives the cross shaft of the box motion, on the latter, are a series of pinion'
wheels, having teeth and blanks, or spaces, these wheels are within an elongated
loop, or eye, of a lever-the extended arm of which is provided with teeth, and
forms a rack, the said looped lever, is not unlike the figure 9 placed horizontally-
The top and bottom inner edges of the loop, have teeth thereon, so as to gear with
the pinions within the loop-The looped levers, are lifted, by pegs, or other pattern
mechanism, so that when the looped end is lifted, its teeth engage with the internal
pinion, whereon the said lever is moved forwards, and as the rack, on its extended
arm, is in gear with a pinion on a cross shaft, the latter receives partial rotation,
and thereby operates an eccentric on the said shaft, and as the eccentric is by
"strap" and connecting rod, attached to a rocking lever, the latter is moved and
by chain or other connection lifts the shuttle box rod, and the boxes are raised-
When there is no peg, under the looped end of the rack lever, the latter drops, and
the teeth on the under edge of its upper part, will engage with the teeth of the
internal spaced pinion, whereon the looped lever, and its rack or toothed arm, will
be drawn backwards, the motion of the pinion strap eccentric and rocking lever,
will be reversed, and the box rod will be drawn down and the shuttle boxes
lowered and so on as indicated by the pattern mechanism.
Dated this 22nd day of August 1884.

I ENOCH OPENSHAW TAYLOR, of Marsden Iron Works, Marsden, in the County
of York, Machine Maker and Ironfounder do hereby declare the nature of my
said invention for "IMPROVEMENTS IN APPARATUS FOR OPERATING RISING AND
FALLING BOXES OF LOOMS FOR WEAVING "and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention-consists of an improved combination-of-mechanism for raising
and lowering the multiple shuttle boxes-so-as to bring any shuttle-and cell in line
with the shuttle race according to pattern being woven and change of shuttle
required.
Such being the nature and object of my said invention, the following is a com-
plete description of same, reference being had to the accompanying drawings forming
a part of this specification.in. which :-

wheel 3, and driving the wheel 4, the latter being fast on the shaft 5, on which is
the barrel wheel 6, keyed on the shaft 5, and having teeth round a part of its cir-
cumference only, as shown at Fig. 4-At 7 are looped racks, the lower arm 8 of
which also forms a rack, and gear with a wheel 9, on the shaft of which are single.
and double eccentrica At 11 are the pattern link pulleys, 12 is a spring lever,
having friction bowl 13, 14 is a double eccentric. The single eccentric 10 being
cast to the spur wheel 10 gearing with rack 8 the double eccentric works loose on
the single eccentric and is worked by a rack 8 and spur wheel 9 having a slot
hole 15 and working on the peg 16 cast on the double eccentric, the strap and
link 18 are connected to the lever 19 working on the fulcrum 20, the lever 19 by
chain 21 and guide pulleys 22, 23, 24, operate the socket piece 25, which is fast on
the box spindle or spear rod 26, 27 shews the shuttle box and its several shuttle
cells.
The action is as follows
The motion of the wheel 6 is continuous and accordingly as the bowls on the
picking chain force the loop (see Fig. 4) to the right, the teeth 28 will gear with
the wheel 6, and the rack be drawn downwards, its rack arm 8 would thus operate
the wheel 9, and by the eccentrics and strap 18, the lever 19 will be operated, and
the change of box effected-When there is no pattern pulley 11, in position for
acting on the rack 28 that is to say, when a blank occurs the bowl 13 of the spring

page_text: lever 12 will cause the teeth 29 of the looped rack 7 to engage with the teeth of
the wheel 6 and whereon the teeth 8 of the rack will operate the wheel, eccentrics,
strap 18 and lever 19 in the opposite direction and the movement of the box will
be reversed The racks 8 are guided and steadied by the pulleys 30 and have
recesses 31 formed therein, which serve to lock and steady the racks in their lower
or raised position and it will be understood that either the single or the double
eccentric will be operated by means described, accordingly as the change is to be
from one or more cells of the box that is to say box after box or skip box, and
that the looped racks 7 and rack arms 8 thereof are on both sides of the wheels
9. 10 (see Fig. 1).
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 I lay
no claim to the use of either single or double eccentrics for purpose aforesaid as
I am aware such are not new, what I do claim is
The looped and arm racks 7, 8, controlled by pattern mechanism and lever such
as 12, so as to engage with and be operated by the wheel 6 the racks 8 operating
in turn the wheels eccentrics, and levers 19 as and for the purpose described, and
as illustrated by annexed drawings,
