Improvements in the Shedding and Drop Box Motions of Looms.
I, ARTHUR SOWDEN of Sowdens Loom Works, Shipley in the County of
York, Loom Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved construction, arrangement and combination
of parts for operating and controlling the healds of looms for weaving and to
appliances for turning or lagging back when necessary.
According to this invention on the tappet shaft of the loom is loosely mounted a
toothed wheel having a long collar or boss, and on said collar or boss is fixed a
barrel or series of lags carried at each of their ends in notched plates and on these
lags are mounted sectional tappet noses. In a frame below the tappet noses, are
mounted the ordinary treadle levers the rummers of which are acted upon by the
tappet noses. The treadle levers are connected by rods with the shaft levers or
the shedding shafts which carry the half moons for raising or lowering the
healds.
The toothed wheel is operated by a carrier wheel operated by spur wheel and on
the axis of the latter is a bevel wheel gearing with a bevel wheel on a cross shaft
the latter bevel wheel being provided with a clutch controlled by fork, bell crank
levers, connecting rods, and handle at the front of the loom.
The cross shaft is driven from any convenient going part and when the clutch
is in gear the bevels drive the spur, carrier and toothed wheels and sectional tappet
noses.
A second bevel wheel on the same shaft as the spur wheel gears with a bevel
wheel on a vertical shaft the upper end of which is provided with a bevel wheel
gearing with a like wheel on a cross shaft on which is a toothed wheel driving a
carrier on the axis of which is a plate or peg wheel driving the star wheel on the
axis of the pattern barrel which controls the shuttle box mechanism, and on this
cross shaft at the front of the loom is a hand wheel.
When the above mentioned clutch is thrown out of gear the several parts and
the box pattern barrel, and the sectional tappet noses can be turned back by hand
by the hand wheel.
In lieu of placing the treadles and tappet noses near the bottom of the loom as
above described the treadles may be mounted vertically in a frame on the top rail
of the loom as described in Specification of Letters Patent Number 15702 dated
the 16th day of September 1891, and granted to the present applicant, and the said
treadles are operated by the sectional tappet noses hereinbefore described such
tappet noses being driven from any convenient going part.
One barrel or circle of lags and sectional tappet noses may be employed or a
series of lags carried over two or more notched plates if required.

Improvements in the Shedding and Drop Box Motions of Looms.
I, ARTHUR SOWDEN of Sowdens Loom Works, Shipley in the County of York,
Loom 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 an improved construction arrangement and combination
of parts constituting an improved shedding motion for operating and controlling
the healds of looms for weaving and to appliances for turning or lagging back
when necessary without affecting other parts of the loom.
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 part of a loom shewing the improved shedding
motion.
Fig. 2 is a back view of part of a loom shewing the improved shedding motion
operated by one circle or barrel of lags mounted on the top rail of the loom.
According to this invention on the tappet shaft 1 of the loom is loosely
mounted a toothed wheel 2 having a long collar or boss 3 and on said collar or
boss 3 is fixed a barrel 4 and series of lags 5 carried at each of their ends in
notched plates 6 and on these lags are mounted sectional tappet noses 7. 7. A
second barrel 4* carried on a stud 8 fixed to the frame of the loom serves to
support one end of the chain of lags 5. In a frame 9 below the tappet noses 7. 7
are mounted on a shaft 10 the ordinary treadle levers 11. 11 the runners 12 of which
are acted upon by the tappet noses 7.7. The treadle levers 11. 11 are connected
by rods 13. 13 with the shaft levers 14. 14 of the shedding shafts 15. 15 which
carry the ordinary half moons for raising or lowering the healds in the well known
manner.
The toothed wheel 2 is operated by a carrier wheel 16 operated by spur wheel 17
and on the axis of the latter is a bevel wheel 18 gearing with a bevel wheel 19
on a cross shaft 20 the latter bevel wheel 19 being provided with a clutch 21 con-
trolled by fork 22 bell crank lever 23 connecting rod 24 bell crank lever 25
connecting rod 26 and handle 27 at the front of the loom.
The cross shaft 20 is driven from any convenient going part and when the
clutch 21 is in gear the bevel 18. 19 drive the spur 17, carrier 16 and toothed
wheels 2 and long collar or boss 3 and the sectional tappet noses 7.7.
A second bevel wheel 27 on the same shaft as the spur wheel 17 gears with a
bevel wheel 28 on a vertical shaft 29 the upper end of which is provided with
a bevel wheel 30 gearing with a like wheel 31 on a cross shaft 32 on which is a
toothed wheel 33 driving a carrier 34 on the axis 35 of which is a plate or peg
wheel 36 driving the star wheel 37 on the axis of the pattern barrel 38 which
controls the shuttle box mechanism and on this cross shaft 32 and at the front of
the loom is a hand wheel 39.
When the above mentioned clutch 21 is thrown out of gear the several parts and
the box pattern barrel, and the sectional tappet noses 7.7 can be turned back by
hand by the hand wheel 39 for "lagging back " or finding a pick or for other
purpose.
In lieu of placing the treadles 11. 11 and tappet noses 7. 7 near the bottom of the
loom as above described and as illustrated by Fig. 1 the treadles 11. 11 may be
mounted vertically (see Fig. 2) in a frame on the top rail of the loom as described
in Specification of Letters Patent Number 15702 dated the 16th day of September
1891, and granted to the present applicant and the said treadles 11. 11 are operated

page_text: by the sectional tappet nose berein before described such tappet noses 7.7 being in
this case preferably mounted on one barrel 4 driven from any convenient going part.
A convenient method of driving the barrel 4 is by means of the wheel 40 on the
axis of the barrel 4, said wheel 40 being driven by a train of wheels from the bevel
wheel 41 on the vertical shaft 42 on the lower end of which is a second bevel
wheel 43 driven by bevel wheel 44, wheel 45 from the crank shaft 45 or other going
part of the loom.
A clutch 46 is controlled by fork 47 bell crank levers connections and handle at
the front of the loom which enables the operative to throw the clutch 46 out of
gear for "lagging back" which is done by means of the handle or wheel 47ª at
the front of the loom and on the-shaft 48.
One barrel 4 or circle of lags and sectional tappet noses 7. 7 may be employed
(see Fig. 2) or a series of lags carried over two or more notched plates 4. 4* (see
Fig. 1) if required or barrels with notched plates at their ends.
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 shedding motion as and for the purpose herein described and substan-
tially as illustrated by Fig. 1 of the accompanying drawings.
2. The sectional tappet noses 7.7 mounted on lags 5. 5, or on a barrel 4 and
operated and operating in the manner herein described and substantially as
illustrated by Fig. 1 of the accompanying drawings.
3. The sectional tappet noses 7.7 mounted on lags 5. 5 on a barrel 4 operated
and operating in the manner herein described and substantially as illustrated by
Fig. 2 of the accompanying drawings.
