PROVISIONAL SPECIFICATION.
Improvements in "Jacks" or Apparatus for Ensuring Differential
Motion on Slubbing, Intermediate, and Roving Frames.
WALTER CHATWOOD BURTON 53 Spotland Road, Rochdale in the County of
Lancaster Engineers Draughtsman do hereby declare the nature of this invention to
be as follows:-
This invention consists of an improved construction and arrangement of apparatus
for the purpose aforesaid. The centrifugal action being obviated or reduced to a
minium.
According to this my invention I attach or fix so as to revolve with; the driving
shaft; a projecting bearing or balanced arm and cross piece for carrying a parallel
shaft.
This shaft is free to revolve in the cross arm bearing and on each end there is
secured a spur wheel. A similar spur, gearing into one of these shaft-end wheels, is
free to revolve upon the main shaft and receives motion from the cones. The other
wheel gears with a similar spur that rides loose upon the Jack or main shaft and which
drives the bobbin driver wheel.
The variable driving motion is derived from the cones, and thence transmitted
through the "Jack" or differential gearing to the bobbin driver, by the differential
action of the four wheels. This peculiar action is produced by one of the wheels in
either pair being constructed with slightly different number of teeth.
Thus the ratio of the gearing, will be equal to the proportion, which the difference
in the number of teeth between the driver & driven bears, to the whole number of
teeth in either, according to whether, the motion be accelerated or retarded.
In some cases I may prefer to use a pair of spur pinions and internal wheels, to
give the said results as before mentioned, or a loose cross-piece in combination with
the spur wheels, as modifications to suit existing motions.
The action is as follows,-On driving shaft commencing to rotate, it carries round
with it the cross piece and the whole mechanism, until the wheel (driven from the
cones) begins to vary its speed from that of the shaft. Immediately any such varia-
tion occurs the speed of the bobbin wheel is altered; for every revolution of difference
between the speeds of the shaft and wheel; in exact proportion to the aforesaid ratio
of gearing.

Improvements in Jacks or Apparatus for Ensuring Differential
Motion on Slubbing, Intermediate, and Roving Frames.
WALTER CHATWOOD BURTON of Ambleside, Flixton, near Manchester, in the
County of Lancaster, and formerly of 53 Spotland Road, Rochdale, Engineers
Draughtsman do hereby declare the nature of this invention and in what manner
the same is to be perforined, to be particularly described and ascertained in and by the
following statement :-
This said Invention consists of an improved construction, and arrangement of
apparatus, for ensuring differential motion, on slubbing, Intermediate & Roving Frames.
The centrifugal action being reduced to a minimum. According to this my invention
I attach or fix to revolve with the driving shaft, a projecting bearing and balance arm,
or cross piece, for carrying a parallel shaft, upon each end of which is secured a spur
wheel. A similar wheel gearing into one of these spurs, rides loose upon the main
רני ...b

page_text: shaft, and is driven from the cone drums. The other spur wheel gears with a similar
spur, that rides loose upon the Jack shaft and which drives the bobbin driver wheel.
A carrier whee being used when required, to render the motion positive in its driving
action. The variable driving motion is derived from the cones, and thence transmitted
through the Jack, or differential gearing, to the bobbin driver. by the differential
action of the four wheels. This peculiar action is produced by one of the wheels in
either pair being constructed with slightly different number of teeth. Thus the ratio
of the gearing will be equal to the proportion, which the difference in the number of
teeth between the driver and the driven, bears to the whole number of teeth in either,
according to whether the motion of the box or balance arm be accelerated or retarded.
In some cases I may prefer to use a loose cross piece, in combination with the four
slightly unequally sized spur wheels, in order to suit the mechanism to existing cone
driving arrangements.
In order that my said invention may be fully understood I have caused to be
annexed hereto drawings with reference to the combination, application and system of
mechanismi.
