Improvements in the Slubbing, Intermediate, and Roving Frames
Used in the Preparation of Fibrous Materials for Spinning.
I PETER SHAW of 93 Gigg Lane Bury in the County of Lancaster
Draughtsman do hereby declare the nature of this invention to be as follows:-
My invention relates particularly to the "swing" or mechanism used to convey
the motion from the driving wheel on the main shaft of the machine to the
bobbin shafts, which are moved upwards and downwards with the bobbin or
traverse rail.
In the arrangement generally adopted the driven wheel on the bobbin shaft is
caused to make part of a revolution more or less than its average speed, according
as the bobbin or traverse rail is rising or falling, thereby causing a constant
varying in speed of the bobbin shaft between the rise and fall of the traverse
rail.
My invention is so designed as to connect, by a train of wheels, and links, the
driving wheel and the bobbin shaft wheel, that the speed of the latter is constant
throughout the rise and fall of the traverse rail. To accomplish this I construct
the parts in the following manner.
I make the driving wheel and the bobbin shaft wheel of equal diameters and
number of teeth, and I convey the motion from the driving wheel to the bobbin
shaft wheel through three carrier wheels; of which the middle one is equal in
diameter and number of teeth to the driving wheel and bobbin shaft wheel, while
the other two carrier wheels are of any convenient size. These five wheels I hold
in gear with each other by means of two links. One link is pivoted on the driving
shaft, and carries two studs, on one of which rotates the first carrier wheel, which
is thus held in gear with the driving wheel, and on the other rotates the second or
middle carrier wheel, which is thus held in gear with the first carrier wheel. The
other link is pivoted at one end on the bobbin shaft, and at the other end on the
stud carried by the first link, on which rotates the second or middle carrier wheel;
and carries a stud on which rotates the third carrier wheel, which is thus held in
gear with the middle carrier wheel and the bobbin shaft wheel.
The action of this combination, if the driving wheel be held stationary, is to
allow the bobbin shaft wheel to rise and fall without any axial movement, and thus
the bobbin shaft will be driven at a constant speed throughout the rise and fall, of
the traverse rail.
It will be understood that although the links are mentioned singly they may be
in pairs, one on each side of the train of. wheels.

I PETER SHAW of 18 Ivy Road, Halliwell, near Bolton, formerly of 93 Gigg
Lane, Bury, in the County of Lancaster, Draughtsman 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 :-
My invention relates particularly to the "swing" or mechanism used to convey
the motion from the driving wheel on the main shaft of the machine to the
bobbin shafts which are moved upwards and downwards with the bobbin or
traverse rail.
In the arrangement generally adopted the driven wheel on the bobbin shaft is
caused to make part of a revolution more or less than its average speed according
as the bobbin or traverse rail is rising or falling, thereby causing a constant varying
in speed of the bobbin shafts between the rise and fall of the traverse rail, and to
overcome this defect is the object of my invention.
In order that my invention may be fully understood and readily carried into effect
I will describe the accompanying sheet of drawings reference being had to the
figures and letters marked thereon.
"
In the drawings, "a" designates the main shaft of the machine, "6" the driving
wheel, "c" and "c" the bobbin shafts, "d" driven wheel on bobbin shaft, "e,"
"f" and "g" carrier wheels, and "h," "," the links supporting the carrier
wheels.
I make the driving wheel "&" and the bobbin shaft wheel "d" of equal
diameters and number of teeth, and 1 convey the motion from the driving
wheel "6" to the bobbin shaft wheel "d" through the three carrier wheels "e,"
"f" and "g"; of which the middle one "" is equal in diameter and number of
teeth to the driving wheel "6" and the bobbin shaft wheel "d," while the other
two carrier wheels "
e "and" 9 are of any convenient size.

e, f g and "d" I hold in gear with each other
2.
"
These five wheels "b," ",
by means of links "" and "
The link "" is pivotted on the driving shaft "a" and carries two studs ""
and "" on one of which "h" rotates the first carrier wheel "e" which is thus
held in gear with the driving wheel "b," and on the other "11" rotates the second
or middle carrier wheel "7" which is thus held in gear with the first carrier
wheel "e."
The link "" is pivotted at one end on the bobbin shaft "c" and at the other
end on the stud """ carried by the link "h" on which rotates the second or
middle carrier wheel "f"; and carries a stud "" on which rotates the third
carrier wheel "g," which is thus held in gear with the middle carrier wheel "ƒ”
and the bobbin shaft wheel "d."
The action of this combination-if the driving wheel be held stationary-is to
allow the bobbin shaft wheel "d" to rise and fall without any axial movement,
and thus the bobbin shafts "c" and "c1" will be driven at a constant speed
throughout the rise and fall of the traverse rail.
It will be understood that although the links are mentioned singly they may be
in pairs one on each side of the train of wheels.
Although I have stated that the wheels "b," "f" and "d" are of equal
diameters and number of teeth, I do not confine myself to them, as I am
aware that a variation of a few teeth between them gives practically the same
result.
The links "h" and "i" may be of any convenient shape as shown in Figs. 1
and 2.

page_text: Having now particularly described and ascertained the nature of my said inven--
tion and in what manner the same is to be performed I declare that what I
claim is :-
In slubbing, intermediate, roving and similar frames, the train of wheels "b,"
"e," "f" "g" and "d" supported by links "h" and "," forming my arrangement.
of swing gearing substantially as and for the purposes herein set forth.
