PROVISIONAL SPECIFICATION.
An Improvement in Mechanism connected with Driving Gearing
of Carding Engine Flats.
RICHARD TYACK, 10, College Street, Accrington, Foreman Mechanic, and
HOWARD & BULLOUGH LIMITED, Globe Works, Accrington, Machinists, do hereby
declare the nature of this invention to be as follows:-
This invention relates to the driving gearing which is commonly made use of
for driving Carding Engine Flats. The latter are linked together by a couple of
endless chains, which travel at a very slow speed on the upper part of the Carding
Engine Bends, the gearing usually consisting of a double pair of wheels and worm
gearing.
It is sometimes requisite to take one of these gears out of position by lowering
the worm wheel stud of one of the worms, necessitating the same to be re-adjusted
and placed in proper gear, which not only takes considerable time but is also
liable to be incorrectly geared with the worm wheel.
The object of our invention is to provide the stud of such driving worm with an
eccentric bored bush, the full part of such bush to face towards the toothed worm
wheel when such worm is set in proper gear for working, so that when the same
is required to be un-geared one half turn of such eccentric bush brings about the
desired effect. A securing pin is also provided to sustain and hold the eccentric
bush in either position so each setting is thereby correctly maintained.

page_text: declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:―
This invention relates to the driving gearing which is commonly made use of
for driving Carding Engine Flats. The latter are linked together by a couple of
endless chains, which travel at a very slow speed on the upper part of the Carding
Engine bends, the gearing usually consisting of a double pair of wheels and worm
gearing.
It is sometimes requisite to take one of these gears out of position by lowering
the worm wheel stud of one of the worms, necessitating the same to be re-adjusted
and placed in proper gear, which not only takes considerable time but is also
liable to be incorrectly geared with the worm wheel.
The object of our invention is to provide the stud of such driving worm with an
eccentric bored bush, the full part of such bush to face towards the toothed worm
wheel when such worm is set in proper gear for working, so that when the same
is required to be ungeared one half turn of such eccentric bush brings about the
desired effect. A securing pin is also provided to sustain and hold the eccentric
bush in either position so each setting is thereby correctly maintained.
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
in which
Sheet 1, Fig. 1 is a side elevation of a few Carding Engine flats A as linked
together by a portion of endless chain B.
C is one of the worms, H is the stud on which the first driving worm E usually
revolves, and D is the eccentric bush on which revolves the first driving worm E
gearing with worm wheel F, the eccentric bush D being fixed by the securing
pin G.
The eccentric bush D is fixed by securing pin G with the full part of the
eccentric in position towards the worm wheel F for sustaining or keeping the
worm E in gear. When it is desired that the worm E should be held out of gear
one half turn by hand is given to the eccentric bush D and the securing pin G
placed through the opposite or reverse side.
Fig. 2 (marked with corresponding letters to Fig. 1) an enlargement is shewn
of eccentric bush with worm out of gear.
Fig. 3 (marked with corresponding letters to Figs. 1 and 2) an enlargement
is shewn of eccentric bush with worm in gear.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. The combination of an eccentric bush D, mounted on a stud H, with locking
appliance G for the purpose of retaining the worm E in or out of gear in pre-
determined positions.
2. The general construction and combination of parts as for purpose herein
described and substantially illustrated by sheet 1 of accompanying drawings.
