IMPROVEMENTS IN MULES FOR SPINNING FIBRES
Year: 1885

page_text: We WILLIAM HOUGHTON and EDWIN KNOWLES both: of California Foundry,
Gomersal, in the County of York, Machine Makers, do hereby declare the nature of
our said invention for "IMPROVEMENTS IN MULES FOR SPINNING FIBRES " to be
as follows:-
This invention relates, to improved "quadrant" lever, combined friction motions,
and gear, for "taking out" and "running in," and mechanism for operating the
"check motion" whereby the rotation of the spindles is arrested.
Quadrant levers according to this our invention consist, of a lever, the quadrant
or segmental portion of which forms a guard, and cover for the quadrant pinion,
the teeth of the quadrant being cast or attached to the inside of the said guard, so
as to entirely avoid danger to the "Minders" and by reason of Being outside the
pinion increased loverage power is given to the quadrant lever.
In combination with the gear for "taking out" and, " taking in" motions of the
carriage, we employ friction rims, cast on, or attached to the gear, and by friction
disc, actuated by catches and levers, so as to secure the requisite motion or traverse,
with gradual starting, and the avoidance of breakage and damage, occasioned by
the use of clutch boxes, as heretofore employed, there being, employed in com-
bination with above, adjusting and regulating screws, whereby the degree of friction
can be determined, and regulated as desired.
"
We arrange the check motion near the scroll and employ a counterbalanced
plate gear wheel, having teeth, and spaces or blanks so as to provide the requisite
intermittent motion-A tappet on the plate wheel acts on a runner" carried by a
stud, attached to the cam lever, and soon as the requisite dwell has taken place,
and the cam lever has operated the counterbalancing weight, attached to the plate
wheel as above referred to, will cause the said wheel to move, or swing into gear,
with the check pinion, and the motion is repeated..

We WILLIAM HOUGHTON and EDWIN KNOWLES, both of California Foundry,
Gomersal, in the County of York, Machine Makers, do hereby declare the nature
of our said invention for IMPROVEMENTS IN MULES FOR SPINNING FIBRES 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 improved "quadrant" lever, and mechanism constituting
and for operating the check motion whereby the rotation of the spindles is
arrested.
Quadrant levers according to this our invention consist of a lever the quadrant
or segmental portion being an internal wheel which forms a guard, and cover for.
the quadrant pinion, the teeth of the quadrant being cast or attached to, the inside
of the said guard, so as to entirely, avoid danger to the "Minders."
We arrange the check motion (near the scroll) and employ in the construction
of the said check motion a counterbalanced plate gear wheel, having teeth and
space or blanks, so as to provide the requisite intermittent motion, a tappet on the
plate wheel acts on a runner carried by a stud attached to the cam lever, and soon
as the requisite dwell has taken place, and the cam lever has operated, the
counterbalancing weight attached to the plate wheel as above referred to, will
cause the said wheel to move or swing into gear with the check pinion and the
motion is repeated.
Such being the nature and object of our 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. sheet 1. is end elevation of Mule shewing Quadrant lever.
Fig. 2. front elevation.
Fig. 3 is detail of quadrant with pinion in section.
Fig. 4. sheet 2 is a back elevation of part of Mule head shewing check motion
applied thereto.
Fig. 5 is an end elevation.
Quadrant levers according to this our invention consist of a lever 1 the quadrant
or segmental portion 2 being an internal wheel 3, which forms a guard 4, and
cover for the quadrant pinion 5, the teeth of the quadrant 2 being cast or attached
to the inside of the said guard 4, so as to entirely avoid danger to the "Minders."
We arrange the check motion' for arresting the motion of the spindles near the
scroll 6 and employ in construction of the said motion a counterbalanced plate
gear wheel 7, having teeth 8, and space or blanks 9, so as to provide the requisite
intermittent motion-A tappet 10 on the plate wheel 7, acts on a runner 11
carried by a stud 12 attached to the cam lever 13, and soon as the requisite dwell
has taken place, and the cam lever 13, has operated, the counterbalancing
weight 14 attached to the plate wheel 7 as above referred to, will cause the said
wheel 7 to move or swing into gear with the check pinion 15 (latter by preference
driven from the cain driving shaft) and the motion is repeated.

page_text: 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-
"
1. The quadrant lever composed of parts 1. 2. 3 and 4 herein described and
substantially as illustrated and for purpose herein set forth.
2. The improved check motion mechanism comprising the combination of parts
6. 7. 10. 13. 14 and 15 for purpose set forth and fully illustrated in and by the
drawings hereunto annexed.
