Improvements in the Construction of Gearing Brackets employed in
Spinning, Twisting, Doubling, Preparing, and similar Frames.
WILLIAM FLECK REYNOLDS of Linfield Foundry, Belfast, County Antrim,
Engineer, do hereby declare the nature of this invention to be as follows:-
In spinning, twisting, doubling, preparing & similar frames, gearing brackets are
used: these are ordinarily mounted on studs or the ends of rollers & carry wheels or.
pinions which are required to gear with other wheels the distance between the
centres of which is variable. This is usually accomplished by causing the gearing
bracket to move around the centre of one of the wheels so that the wheel or pinion
mounted on bracket approaches to or recedes from the other wheel. The gearing
bracket is provided with a slot, for securing bolt, struck from the centre around
which bracket moves so that play is thereby given for its motion through the
required distance.
With the existing arrangement the accurate setting in gear of the various sizes
of wheels or pinions mounted on gearing bracket is difficult & the object of the
present invention is to obviate this difficulty: this I accomplish in the following
way.
Í furnish the gearing brackets with circular racks, cast on or fitted to them in
suitable positions, & cause to gear in these tangent screws or ordinary pinions
bringing the axles of either screws or pinions to a convenient position for hand of
operator who is making the required change in the positions of centres of wheels.

COMPLETE SPECIFICATION.
Improvements in the Construction of Gearing Brackets employed in
Spinning, Twisting, Doubling, Preparing, and similar Frames.
WILLIAM FLECK REYNOLDS of Linfield Foundry Belfast, County Antrim,
Ireland Engineer, 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 :—
In spinning, twisting, doubling, preparing & similar frames, gearing brackets are
used, these are ordinarily mounted on studs or the ends of rollers & carry wheels
or pinions which are required to gear with other wheels, the distance between the
centres of which is variable.
This is usually accomplished by causing the gearing bracket to move around the
centre of one of the wheels so that the wheel or pinion mounted on bracket
approaches to or recedes from the other wheel.
The gearing bracket is provided with a slot for securing bolt struck from the
centre around which bracket moves so that play is thereby given for its motion
through the required distance.
With the existing arrangement the accurate setting in gear of the various sizes
of wheels or pinions mounted on gearing bracket is difficult & the object of the
present invention is to obviate this difficulty. This I accomplish in the following
manner.
I furnish the gearing brackets with circular racks cast on, cut in, or fitted to
them in suitable positions & cause to gear in these tangent screws or ordinary
pinions, spur or bevel, bringing the axles of either screws or pinions to a convenient

page_text: position on machine for hand of operator who is making the required change in the
positions of centres of wheels.
The accompanying drawing is that of a gearing bracket employed on wet
spinning frames & will serve to illustrate, for all of the above mentioned classes of
machinery, wherein my invention consists.
In the drawing, K, is the gearing bracket, A, the centre around which it moves,
B, a slot in which a stud is fixed; this stud carries at different times pinions of
various diameters; all of which must gear with wheel or piuion mounted on
centre, M. Moreover the distance between centres A & M is also variable: for
the easy & accurate setting of these pinions I cut cast or fit a set of teeth, T,
around part of the circumference of gearing bracket & cause to gear with these the
tangent screw, E. Mounted on bracket, F, actuated by hand wheel, H, the
bolt, D, secures gearing bracket, after setting, to framing of machine. C, is a slot
provided in gearing bracket to permit it to traverse around bolt D.
The operation of setting is as follows. After slackening bolt D, the required
wheel or pinion is mounted on stud in slot, B, & the hand wheel H is revolved
until the pinion on stud assumes the required position with relation to centre, M,
bolt, D, is then fastened.
It is found, in practice, that the tightening of this bolt causes considerable wear
on bearing of roller, A, to counteract this I provide a bored out or fitted
bearing, J, to worm, E, which takes the strain imparted by spanner in tightening
bolt, D.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is
1st. The use of gearing brackets in spinning, twisting, doubling preparing &
similar frames provided with teeth to take tangent screws, bevel, spur, or helical
wheels, whether these teeth are cast on, cut in, or fitted to the brackets.
2nd. The combination of worm teeth tangent screw & bracket provided with
bearing for latter, cast on or fitted to supporting bracket, as drawn & described.
