We WALTER THOMPSON of Victoria Mill Blackburn, in the County of Lancaster
Cotton Manufacturer and FRANCIS WILLIAM JEPSON of 95 Infirmary Street
Blackburn, aforesaid Cotton Mill Manager, do hereby declare the nature of our
invention for IMPROVEMENTS IN SHEDDING MOTIONS OF LOOMS FOR WEAVING, to be
as follows:-
This invention consists of an improved construction arrangement and combination
of parts for operating the healds of looms for weaving.
According to this invention we employ a bell crank or L lever carried on a stud
and caused to rock or oscillate by means of a connecting rod attached to the lower
arm of the lever and to an excentric on the bottom shaft of the loom. The vertical
arm of the lever carries at its upper end a pair of rods, one being a pusher and the
other a puller or draw catch. The rods referred to are under the control of peg or
other pattern mechanism and as the ✓ lever moves to and fro" the pusher rod or
the draw rod will impart to a notched wheel on the shaft of the shedding engine
partial rotation in one or the other directions.
On the shedding shaft is a star wheel which receives a like partial rotation and
thereby raises or lowers a heald lever on the under side of which is a lug or tappet
piece, the lever referred to rocks on a stud and its other or shorter end is toothed and
gears with a like lever for operating the opposite end of the heald staves and for the
purpose of lifting the healds at both their ends. The pattern mechanism receives its
motion from a catch operated from the lever, the pegs in turn lifting or lowering
the push or the draw rods accordingly as the shedding shaft and wheels are to be
turned in one or the other direction by means of levers and cords connected with the
said push and pull levers and operated by lattice and pegs.

page_text: We, WALTER THOMPSON of Victoria Mill, Blackburn in the County of Lancaster,
Cotton Manufacturer and FRANCIS WILLIAM JEPSON of No. 95 Infirmary Street,
Blackburn aforesaid Cotton Mill Manager, 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 consists of an improved construction, arrangement and combination
of parts for operating the healds of looms for weaving.
According to this invention we employ a bell crank or T lever carried on a stud
and caused to rock or oscillato by means of a connecting rod attached to the arm of
the lever, and to an eccentric or crank on the bottom shaft of the Loom.
The arm of the T lever carries at its upper end a pair of rods forming pullers or
draw catches.
The rods referred to are under the control of peg or other pattern mechanism and as
the lever moves "to and fro" the rod will impart to a notched wheel on the shaft of
the shedding engine partial rotation. On the shedding shaft is a star or tappet wheel
which receives a like partial rotation, and thereby raises or lowers a heald lever on the
under side of which is a lug or tappet picce the lever referred to rocks on a stud and
its other or shorter end is toothed and gears with a like lever for operating the
opposite end of the heald staves and for the purpose of lifting the healds at both
their ends.
The pattern mechanism receives its motion from a catch operated from the T lever,
the pegs in turn lifting or lowering the rods accordingly; as the shedding shaft and
wheels are to be turned.
Such being the nature and object of our 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 our improved shedding motion, the several views on
sheet 2 are details of the star or tappet wheel.
According to this invention we employ a bell crank or T lever 1 carried on a
stud 2, and caused to rock or oscillate by means of a connecting rod 3 attached to the
arm 4 of the T lever 1, and to an eccentric or crank 5 on the bottom shaft 6 of the
loom.
The arm 7 of the T lever 1 carries a pair of rods 8, 8, having a hook or finger 8^
at their ends which form pull or draw catches. The rods 8, 8, referred to are under
the control of peg or other pattern mechanism 9, the pegs 10 of which lift the
levers 11 (one portion of which is composed of wire for the purpose of lightness as
shewn at 114) and thereby lift the rods 8, 8, by means of the side pieces 12, 12, and
as the lever moves to and fro" the rods 8, 8, will impart to the wheel 13 on the
shaft 14 of the shedding engine partial rotation.
On the shedding shaft 14 is a star or tappet wheel 15 composed of a series of
detachable tappets 16 (see Fig. 2) which may be arranged around the central plate

page_text: wheel 15 on the studs or blocks 18 the aperture 19 of the tappets 16 being of size and
form corresponding to the parts 18, so that when placed thereon they lock and hold
securely against the curved outer circumference of the plate wheel 15. The tappets
may in form and number be applied to give varying effect to the heald levers 17 and
consequently to the healds, the star or tappet wheels 15 are bolted to each other as
at 21, there being a number of these wheels corresponding to the number of heald
levers 17. The star or tappet wheel 15 receives a like partial rotation to the wheel 13,
and thereby raises or lowers a heald lever 17, on the under side of which is a lug or
tappet piece 184, the lever 17 referred to rocks on a stud 17A and its other or shorter
end is toothed and gears with a like lever 194 for operating the opposite end of the
heald staves, and for the purpose of lifting the healds at both their ends.
The pattern mechanism receives its motion from a catch 20 operated from the
T lever 1, the catch 20 being raised or lowered by means of the rod A and elastic B
on lever 11 the rods 11^ in turn lifting or lowering the rods 8, 8, accordingly as the
shedding shaft 14 and wheels 13. 15, are to be turned by means of levers 8, 8, and
catches 8 8 connected with the T lever 1.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is,
The lever 1 and parts 8 controlled by and in combination with the levers 11
together with the wheel 13, and star or tappet wheel 15 for purpose of operating the
heald levers such as 17, and the several parts as are herein described and illustrated
by annexed drawings.
