PROVISIONAL SPECIFICATION.
Improvements in Means for Securing Coupling Wheels on Shafts for
Roving and other like Frames.
EDWARD HOTHERSALL, Globe Works, Accrington, Foreman Mechanic, and
HOWARD & BULLOUGHI LIMITED, Globe Works, Accrington, Machinists, do hereby
declare the nature of this invention to be as follows:-
This invention relates to the keying and coupling of bobbin and spindle shaft
wheels in roving and other like cotton preparing frames, and consists of key
shaped in the manner of what is known as the Woodruff patent key, with the
exception that two of the same are formed out of one piece of metal, with a coup-
ling part for joining the two keys together, forming a double key, so that when
made use of, two shaft ends may be joined together, and held securely. One end
of the so called double key is let into the end of one shaft; the
other end of the key is let into the other shaft end, so that when a coupling
is placed over the abutting part of the shafts, the wheel boss covers the ends of
the two shafts, and also holds the double key in position. At the same time it
gives liberty for the wheels as made use of for this purpose being adjusted to the
wheel it gears with. Another advantage obtained by the use of this improvement
is that so long as the keys are held in keyways of the shaft ends, the latter cannot
separate endways from each other.

EDWARD HOTHERSALL, Globe Works, Accrington, Foreman Mechanic, and

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:

of the so called double key is let into the end of one shaft; the
other end of the key is let into the other shaft end, so that when a coupling

is that so long as the keys are held in keyways of the shaft ends, the latter cannot
separate endways from each other..
Such being the nature and object of our invention, the following is a complete
description of same, reference being made to the accompanying sheet of drawings.
Fig. 1 is an end view of a shaft coupling wheel having the usual split coupling
boss secured to same by set screws, and to which our invention is added at B of
the sunk keyway A, being an end view of our so called double key, which is shown
separately at Fig. 3 and 4. Fig. 2 shows same in position. Shaft A is illustrated
with a portion taken away, also a part of the coupling boss for better showing
double key as holding the two shafts from getting apart.
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:
The construction and use of a key having their two ends so formed and made
use of for purposes as described and illustrated by the sheet of drawings annexed,
which form a part of this specification.
