page_text: I, FRANK LEEMING of the firm of John Leeming and Son, North Vale Works,
Bradford, in the County of York, Machine Maker, do hereby declare the nature of my
invention for "IMPROVEMENTS IN APPARATUS FOR OPERATING THE RISING AND FALLING
SHUTTLE BOXES, AND CONTROLLING THE PICKING MOTION OF LOOMS FOR WEAVING to
be as follows:-
"
This invention relates to an improved construction, combination, and arrangement of
parts for operating rising and falling boxes for the shuttles of looms and being an
improvement upon inventions for which Letters Patent No. 15484 and No. 1597984
were granted to me.
For purpose aforesaid I mount the shuttle boxes and rod upon the outer end of the
main or shuttle box lever, there being a small or duplicate lever connected with the
main lever, and both are connected by vertical rods with crank pins secured in the face
or plate of two star wheels, the latter being carried upon studs fixed in the framing of
the loom one on each side of, and linable with the centre of the crank shaft.
These two star wheels lock upon a centre barrel on the crank shaft, and which said barrel
carries two movable segment wheels controlled by forks mounted above the centre of the
barrel, the barrel has also teeth on a portion of its circumference which engage with
the teeth of another star wheel mounted upon the same stud as one of the box star
wheels referred to, and which locks upon the same centre barrel, the third star wheel
drives by means of bevel wheel and upright shaft the chain barrel and indicating or
pattern chain the indicating levers resting upon the pattern chain are connected by

page_text: rods and arms on horizontal shaft with the clutch forks which together with the
segment wheels they operate according to the arrangement of the pattern chain and
pattern required. The clutch forks are connected or linked by a spiral spring.
In connection with the motion for controlling the picking a third indicating lever is
connected by rod with a clutch fork controlling the segment wheel which moves the
star wheel connected with the picking motion thereby to ensure direct action and
control from the pattern chain, and to dispense with intermediate appliances heretofore
employed.

Improvements in Apparatus for Operating the Rising and Falling
Shuttle Boxes and Controlling the Picking Motion of Looms for
Weaving.
I, FRANK LEEMING of the firm of John Leeming & Son North Vale Works,
Bradford in the County of York, Machine Maker, do hereby declare the nature of
this invention and in what manner the same is to be performed, tó be particularly
described and ascertained in and by the following statement:-
This invention relates to an improved construction, combination and arrangement of
parts for operating the rising and falling boxes for the shuttles of looms and being an
improvement upon inventions for which Letters Patent No. 1548484 and No. 1597984
were granted to me.
For purpose aforesaid I mount the shuttle boxes and rod upon the outer end of the
main or shuttle lever, connected by vertical rods with crank pins secured in the face
or plate of two star wheels the latter being carried upon studs fixed in the framing of
the loom one on each side of and linable with the centre of the crank shaft.
These two star wheels lock upon a centre barrel on the crank shaft, and which said
barrel carries two moveable segment wheels controlled by forks mounted above the
centre of the barrel the barrel has also teeth on a portion of its circumference which
engage with the teeth of another star wheel mounted upon the same stud of the box
star wheels referred to, and which locks upon the centre barrel, the third star wheel
drives by means of bevel wheel and upright shaft, the chain barrel and indicating or
pattern chain-the indicating levers resting upon the pattern chain are connected by
rods and arms on horizontal shafts with the clutch forks which together with the
segment wheels the operate according to the arrangement of the pattern chain and
pattern required.
The clutch forks are connected or linked by a spiral spring.
In connection with the motion for controlling the picking a third indicating lever is
connected by rod with a clutch fork controlling the segment wheel which moves the
star wheel connected with the picking motion therefore to ensure direct action and
control from the pattern chain and to dispense with intermediate appliances heretofore
employed.
Such being the nature and object of this my invention, the following is a complete
description of same reference being had to the accompanying drawings:-
Fig. 1 is a side elevation of my improved apparatus.
Fig. 2 is an end view of Fig. 1.
Fig. 3 is a side elevation of the apparatus when in lieu of links and pins I employ
sheet cards.
The remaining figures on sheets 2 & 3 are details.
For purpose aforesaid I mount the shuttle boxes and rod 1 upon the outer end of the
main or shuttle box lever 2 connected by vertical rods 3-4 with crank pins secured

page_text: in the face or plate of two star wheels 5-6 the latter being carried upon studs 7-8
fixed in the framing 9 of the loom one on each side of and linable with the centre of
the crank shaft 10.
These two star wheels 5-6 lock upon a centre barrel 11 on the crank shaft 10,
and which said barrel carries two moveable segment wheels 12-13 (see detail)
controlled by forks 14, 15 mounted above the centre of the barrel 11, the said barrel
has also teeth 16 on a portion of its circumference which engage with the teeth of
another star wheel 17 mounted upon the stud 7 of the box star wheel 6 referred to,
and which locks upon the centre barrel 11, the third star wheel 17 drives by means of
bevel wheel 18 and shaft 19 the chain barrel and indicating or pattern chain 20-the
indicating levers 21, 22 resting upon the pattern chain are connected by rods 24, 25
and arms 24, 25^ on horizontal shafts 26, 27, with the clutch forks 14, 15 which they
operate according to the arrangement of the pattern chain 20 and pattern required.
The clutch forks 14-15 are connected or linked by a spiral spring 29.
In connection with the motion for controlling the picking a third indicating lever 23
is connected by rod 31 with a clutch fork 32 controlling the segment wheel 33, which
moves the star wheel 34 connected with the picking motion thereby to ensure direct
action and control from the pattern chain, and to dispense with intermediate appliances
heretofore employed.
The construction of the centre barrel and its parts is clearly shown by the enlarged
detail drawings in sheet 3 and it will he understood that the centre barrel is keyed fast
on the crank shaft and segments 12-13 are under control of the forks 14-15 so that
if the teeth of a segment be opposite the star 5 it will give half revolution to the star
wheel 5 and its rod 3 will thereby be raised or lowered but if the blank portion of the
segment be opposite the star, thereon there will be no motion to the wheel or rods-so
exacting is the action of the segment 13 and its parts and rod 4.
In lieu of the pattern chain composed of links and pins, I may employ sheet cards
such as 1 (see sheet 2) in which case the indicating levers 21, 22, 23; rest upon a
cam 2 keyed on to the plate peg wheel 324 which at each revolution turns by means
of peg 35 star wheel 33 on axis of which is secured the flat card cylinder 34*.
The indicating levers 21, 22, are connected by rods 24-25 previously described.
The cam plate 32 is driven by shaft 19 by bevel wheel 18 direct from the crank
shaft 10.
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 what
I claim is :-
The centre barrel 11 having the moveable segments 12-13, controlled from the
pattern mechanism in combination with and for operating the star wheels 5-6 for
purpose described and illustrated by annexed drawings.
