Improvements in Shuttle Box Mechanism of Looms for Weaving.
I, GEORGE HERBERT HODGSON, of Thornton Road, Bradford, in the County
of York, Machine Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the method of and means employed for
controlling the rising and falling, and circular shuttle boxes of looms for weaving,
being designed for bringing one or other of the cells lineable with the race
according to the pattern required and as indicated by the pattern cards. By the
arrangement and combination of parts hereinafter described I am enablel to
control the boxes by means of a rotating pattern barrel with one row of plain pegs,
such pattern barrel being on the same shaft as the pattern barrel which controls the
shedding mechanism. The pattern barrels for controlling the shedding mechanism
and the boxes, being on the same shaft, the loom can be "turned back" without
danger of crossing the patterns, and fewer cards are required to produce any given
pattern. The card cylinder for the box can be turned at any time with the dobby
and without interfering with the correct motion of the box lever.
According to this invention I employ a pattern barrel as ordinary for operating
the shedding mechanism, but this barrel has in each lattice a double row of pegs. On
the same shaft as the above mentioned barrel is a second pattern barrel, each lattice
of which has a single row or part row of pegs. These pegs operate on tumbler
levers to which are attached rods connecting the levers with cranked levers mounted
on a fulcrum stud. The lower ends of the cranked levers form fingers which rest
against the back catches of the bottom levers of the box pulling rods. The back
catches are mounted on studs, and provided with springs which pull them clear of
the lifting lever unless operated upon by one of the fingers. When a peg lifts one
of the tumbler lever, the latter by its connecting rod, causes the cranked lever to
move the finger away from the back catch, which then falls clear of the lifting
lever. If no peg comes under the lever, the weight of the latter causes the cranked
lever to press the back catch so that it engages with the lifting lever and is operated
thereby.

Improvements in Shuttle Box Mechanism of Looms for Weaving.
I, GEORGE HERBERT HODGSON, of Thornton Road, 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, to be particularly described and
ascertained in and by the following statement :-
This invention relates to improvements in the method of and means employed for

page_text: bringing one or other of the cells lineable with the race according to the pattern
required, and as indicated by the pattern cards.
By the arrangement and combination of parts hereinafter described, I am enabled
to control the boxes by means of a rotating pattern barrel with one row of plain
pegs, such pattern barrel being on the same shaft as the pattern barrel which
controls the shedding mechanism. The pattern barrels for controlling the shedding
mechanism and the boxes being on the same shaft, the loom can be "turned back
without danger of crossing the patterns, and fewer cards are required to produce
any given pattern. The card cylinder for the box can be turned at any time
with the dobby, and without interfering with the correct motion of the box
lever.
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,
in which :-
Fig. 1 is an end elevation of the improved shuttle box mechanism.
Fig. 2 is a front elevation of part of Fig. 1.
According to this invention, I employ a pattern barrel 1 as ordinary for operating
the shedding mechanism, and this barrel 1 has in each lattice a double row of pegs
as ordinarily used on circular box looms. On the same shaft 2 as the above
mentioned barrel 1, is a second pattern barrel 3, each lattice of which has a single
row, or part row of pegs. These pegs operate on two tumbler levers 4, to which
are attached rods 5 connecting the levers 4 with two cranked levers 6, mounted on
a fulcrum stud 7. The lower ends of the cranked levers 6 form fingers 8 which
rest against the back catches 9 of the bottom levers 10 of the box pulling rods 11.
The back catches 9 are mounted on stude 12, and are provided with springs 13
which pull them clear of the lifting lever 14, unless operated upon by one of the
fingers. When a peg lifts one of the tumbler levers 4, the latter, by its connecting
rod 5, causes the cranked lever 6 to move its finger 8 away from the back catch 9,
which then falls clear of, or by the spring 13 is pulled clear of, the lifting lever 14.
If no peg comes under the lever 4, the weight of the latter causes the cranked
lever 6 to press the back catch 9, so that it engages with the lifting lever 14, and is
operated thereby in the usual manner, and so the circular boxes are operated.
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 I
claim is :-
(1) The general construction, arrangement, and combination of parts constituting
the improved circular shuttle box mechanism, as and for the purpose herein
described, and substantially as illustrated by Fig. 1 of the annexed drawings..
(2) The pattern barrel i, shaft 2, pattern barrel 3, levers 4. 4, rods 5. 5, cranked
levers 6. 6, and catches 9. 9, all in combination, as and for the purpose herein
described, and substantially as illustrated by Fig. 1 of the annexed drawings.
