PROVISIONAL SPECIFICATION.
An Improved Construction of the Winding Arm and Quadrant of
Self-acting Mules and Twiners.
We, ASA LEES AND COMPANY, LIMITED, of Soho Iron Works, Oldham, in the
County of Lancaster, Machine Makers, and JOHN CLEGG, of the same address,
Manager of the Mule Department, do hereby declare the nature of this invention
to be as follows:-
1
Our invention relates to an improved construction of the winding arm and
quadrant of self acting mules and twiners, and the object of our invention is
to improve the gearing between the teeth on the quadrant and the pinion, and
to prevent breakage of the teeth.
We are aware that the winding arm and quadrant has previously been made
in two parts but in such cases the central boss has been cast with the winding
arm and it was difficult to connect the parts and finish the teeth on the quadrant
satisfactorily.
According to our invention we cast the central boss on the quadrant portion
and we also cast a lug or two or more lugs on the quadrant and cast corresponding
lugs on the winding arm. The quadrant when cast is put in a lathe and bored
and turned on its periphery and elsewhere as required and in place of casting
the teeth as usual we propose to machine cut all the teeth.
The winding arm is then fitted to the quadrant and the lugs on each part
bored to receive turned bolts by which the quadrant and arm are secured together.
In this manner of manufacture the teeth on the quadrant can be made as wide as
desired and both quadrant and winding arm can be made in the same vertical
plane.

An Improved Construction of the Winding Arm and Quadrant or
Self-acting Mules and Twiners.
We, ASA LEES AND COMPANY, LIMITED, of Soho Iron Works, Oldham, in the
County of Lancaster, Machine Makers, and JOIN CLEGG, of the same address,
Manager of the Mule Department, 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:
Our invention relates to an improved construction of the winding arm and

page_text: quadrant of self acting mules and twiners, and the object of our invention is
to improve the gearing between the teeth on the quadrant and the pinion, and
to prevent breakage of the teeth.
We are aware that the winding arm and quadrant has previously been made
in two parts but in such cases the central boss has been cast with the winding
arm and it was difficult to connect the parts and finish the teeth on the quadrant
satisfactorily.
According to our invention we cast the central boss on the quadrant portion
and we also cast a lug or two or more lugs on the quadrant and cast corresponding
lugs on the winding arm. The quadrant when cast is put in a lathe and bored
and turned on its periphery and elsewhere as required and in place of casting
the teeth as usual we propose to machine cut all the teeth.
The winding arm is then fitted to the quadrant and the lugs on each part
bored to receive turned bolts by which the quadrant and arm are secured together.
In the accompanying sheet of drawings
Fig. 1 is a side elevation, Fig. 2 a plan and Fig. 3 a detail view of the winding
arın and quadrant of a self acting mule or twiner made according to our invention.
In these views, a designates the winding arm to which are cast two lugs aa³,
the quadrant provided with two corresponding lugs to receive bolts c;
the quadrant is provided with a long boss which is mounted upon a short shaft d
carried by the headstock and the arm through which the shaft does not pass
carries a screw e and a nut f, as usual.
In constructing our improved winding arm and quadrant we cast the two
parts separately and then bore out the hole in the boss of the quadrant b to fit the
shaft d also when the teeth on the quadrant are to be machine cut we turn and face
the periphery ready for cutting the teeth, and face the lugs a¹a. After the teeth
have been cut and when, the winding arm has been machined where required
and faced on the lugs, the arm and quadrant are laid together and drilled
through the lugs to receive the bolts c, by which the combined parts are then
secured. together.
In this manner of manufacture the teeth on the quadrant can be made as wide as
desired and both quadrant and winding arm can be made in the same vertical
plane, and further the winding arm can be removed and replaced without dis-
turbing the short shaft or centre stud d.
Although we prefer to cut the teeth on the quadrant, we do not make this an
essential feature of our invention.
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:-
A winding arm and quadrant formed in separate parts and having the boss
which fits upon the short shaft or centre stud cast with the wheel (or quadrant)
portion only, by which arrangement the winding arm can be removed without
disturbing the short shaft or centre stud substantially as and for the purposes
herein set forth.
