I GEORGE HELBERT HODGSON of Laycocks Mill, Thornton Road Bradford in the
County of York Machine Maker do hereby declare the nature of this invention to be
as follows:-
66
This invention relates to mechanism for operating the healds as also the rising and
falling or Drop boxes" of looms for weaving, and consists of an improved combina-
tion and arrangement of parts whereby the use of much smaller operating looped racks
are available and the locking or steadying of either healds or boxes is ensured during
any required number of beats or of picks.
Apparatus for purpose aforesaid according to this my said invention comprises a
bevel wheel on the upright shaft engaging with a like wheel on a vertical shaft, at
the upper end of which is another bevel wheel gearing with a like wheel on a horizontal
stud, the latter bevel wheel drives a spaced tooth wheel at each revolution engage with
the teeth or a spaced pinion, the latter being on the axis of a long or broad pinion which
is within the loop of a series of internal geared loop levers.
The loop has an extended arm or rack which gears with a sector wheel on a
disc, in the latter is a stud carrying a lever, connected at its other end with
Llever for operating the connections with the healds, or for operating the shuttle
box moving lever.
There is sufficient space in the two opposite upper and lower loops of the rack,
in which their operating pinion can revolve, clear of or out of gear with the rack,
so that any desired number of beats of the slay or of picks of the shuttle, may be
made, without movement of the racks, and the lever connecting the sector wheel
and disc being then on the dead centre the whole is securely locke and held.
The connections for operating the healds comprise the ordinary levers and cords
or links. For operating the shuttle box the lever carries a vertical rod, the lower

page_text: part of which forms a rack gearing with a pinion, the latter operates one or more
eccentrics (according to the number of cells in the shuttle box) whereby the shuttle
box lever and shuttle box rod are moved according to the cell shuttle to be brought
linable with the shuttles race.
The looped rack levers are put into gear or dropped out of gear therewith through
the agency of pattern peg and blanks or other like devices used for controlling pattern
or shuttle box motions.

I, GEORGE HERBERT HODGSON of Laycocks Mill, 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 mechanism for operating the healds as also the rising and
falling or "drop boxes." of looms for weaving and consists of an improved combination
and arrangement of parts whereby the use of much smaller operating looped racks are
available, and the locking or steadying of either healds or boxes is ensured during any
required number of beats or of picks.
Apparatus for purpose aforesaid according to this my said invention comprises a
bevel wheel on the crank shaft engaging with a like wheel on a vertical shaft, at
the upper end of which is another bevel wheel gearing with a like wheel on a
horizontal stud, the latter bevel wheel drives a spaced tooth wheel which at each
revolution, engages with the teeth of a spaced pinion, the latter being on the axis
of a long or broad pinion which is within the loop of a series of internal geared
loop levers.
The loop has an extended arm or rack which gears with a sector wheel on a
disc, in the latter is a stud carrying a lever connected at its other end with
Llever for operating the connections with the healds, or for operating the shuttle
box moving lever.
1.
There is sufficient space in the two opposite upper and lower loops of the rack in
which their operating pinion can revolve clear of or out of gear with the rack, so
that any desired number of beats of the slay or of picks of the shuttle may be made
without movement of the racks, and the lever connecting the sector wheel and disc
being then on the dead centre, the whole is securely linked and held.
The connections for operating the healds comprise the ordinary L levers and cords
or links.
For operating the shuttle box the L lever carries a vertical rod, the
lower part of which forms a rack gearing with a pinion, the latter operates one or
more eccentrics (according to the number of cells in the shuttle box) whereby the
shuttle box lever and shuttle box rod are moved according to the cell and shuttle
to be brought linable with the shuttle rack.
The looped rack levers are put into gear or out of gear through the agency of the
pattern bowls, cards, or pegs, and blanks or other like devices used for controlling
pattern or shuttle box motions.
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.

page_text: DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side view of improved mechanism for purpose aforesaid.
Fig. 2 is an end view of same.
Fig. 3 is improved mechanism for operating rising and falling shuttle boxes.
Apparatus for purpose aforesaid according to this my said invention comprises a
bevel wheel 1 on the crank shaft 2 engaging with a like wheel 3 on a vertical shaft 4,
at the upper end of which is another bevel wheel 5 gearing with a like wheel 6, on a
horizontal stud 7, the latter bevel wheel 6 drives a spaced tooth wheel 8 which at each
revolution engages with the teeth of a spaced pinion 9, the latter being on the axis 10
of a long or broad pinion 11 which is within the loop 12 of a series of internal geared
loop levers 13.
The loop 13 has an extended arm or rack 14 which gears with a sector wheel 15 on
a disc 16, in the latter is a stud 17, carrying a lever 18 connected at its other end
with the lever 19 for operating the connections with the healds 20, or for operating
the shuttle box moving lever.
There is sufficient space in the two opposite upper and lower loops 13 of the rack,
in which their operating pinion 11 can revolve clear of or out of gear with the rack so
that any desired number of beats of the slay, or of picks of the shuttle may be made
without movement of the racks 14 and the lever connecting the sector wheel 15
and disc 16 being then on the dead centre the whole is securely locked, and held.
The connections for operating the healds 20 comprise the ordinary L lever 19 and
cords or links 21.
For operating the shuttle box the L levers 19, 19 carry vertical rods 22, 22, the
lower ends of which form racks 23, 23, gearing with the sector wheels 24, 24*.
The sector wheel 24 operating the small eccentric 25 and the sector wheel 24
operating the larger eccentric 25 through the agency of the rods 22, 22, and
racks 23, 23. When the sector wheel 24 and consequently the small eccentric 25 is
operated by the rack 23 the link 28 and end 26 of the box lever. 27 is depressed
on its.fulcrum 29 and the shuttle box raised one box, the large eccentric 25* raising
two boxes, and when both eccentrics are moved simultaneously a third box is raised
and brought lineable with the shuttle race.
The sector wheel 24 is cast to the eccentric 25 and the sector wheel 24* is cast
to a plate 30 on the opposite side of which is a recess or guide piece 31 in which
the lump 32 cast on the large eccentric works, and allows the same to rise or fall,
when the small eccentric is operated.
The looped rack levers are put into gear or dropped out of gear through the
agency of pattern bowls, or cords or other like devices used for controlling pattern or
shuttle box motions.
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 ;
The spaced wheels 8-9-together with the looped rack 13-14-sector wheel 15,
dise 16, having the curved lever 18, centred thereto as shewn, and all in combina-
tion for securing and locking the cranked lever 19 for operating the healds or drop
boxes of looms.
