IMPROVEMENTS IN MACHINERY FOR SPINNING OR TWISTING COARSE YARNS."
Year: 1881

page_text: LETTERS PATENT to Abram Combe, Machinist, of Belfast, in the County of
Antrim, Ireland, for an Invention of "IMPROVEMENTS IN MACHINERY FOR
SPINNING OR TWISTING COARSE YARNS."
PROVISIONAL SPECIFICATION left by the said Abram Combe at the Office
of the Commissioners of Patents on the 9th March 1881.

"IMPROVEMENTS IN MACHINERY FOR SPINNING OR TWISTING COARSE YARNS."
These improvements relate especially to borizontal spindled spinning or twisting
frames, such as are used for spinning or twisting coarse yarns.
The improvements consist in a novel method of traversing the yarn upon the
bobbins which are concentric with the flyers; the guiding pullies or eyes which
conduct the yarn on to the bobbins are made to move backwards and forwards
along the legs of the flyers by means of right and left handed screws with
continuous threads, to which motion is communicated from a sun and planet
motion on the flyers.
The guiding pullies or eyes being made to travel backwards and forwards along
the legs of the flyers, instead of the bobbins moving in the direction of their axes
inside the flyers as at present, permits the legs of the flyers and the portions of
the spindles inside the flyers (for supporting the bobbins) to have only about one
half their present length, and they are consequently much stiffer, besides which the
traversing motions outside the flyers for moving the bobbins are dispensed with,
and so the machines are considerably shortened in length, and at the same time
strengthened.

IMPROVEMENTS IN MACHINERY FOR SPINNING OR TWISTING COARSE YARNS."
These improvements relate specially to horizontal spindled spinning or twisting
frames, such as are used for spinning or twisting coarse yarns.
The improvements consist in a novel method of traversing the yarn upon the
bobbins which are concentric with the flyers. The method of doing this will be
understood from the following description, reference being had to the accompanying
Drawing, wherein the same Figures and letters of reference always apply to the
same or like parts.
The Drawings illustrate two arrangements of flyers, one (Figures 1 and 2)
having hauling pullies inside the flyer for pulling the yarn into the flyer, whilst
in the other, as shewn in Figures 3 and 4, the yarn is supplied by rollers or pullies
situate outside the flyer and separate therefrom.
Figure 1 is a side elevation partly in section of a horizontal spindle and flyer
fitted according to my Invention with right and left handed screws for traversing
yarn guide pullies or eyes from end to end of a stationary bobbin; and Fig. 2 is a
cross section shewing the head of the flyer and the gearing in connection therewith
by which the screws are driven.
Fig. 3 is a sectional elevation of a bobbin and flyer with special gearing provided
for driving the screw spindles, and Fig. 4 is a cross section shewing this gearing in
side view.
In both these arrangements a is the flyer driven in the usual manner by means
of a belt pulley a², and b is the stationary bobbin, which is "dragged" or retarded
in order to give the requisite "take up" of the yarn by means of a belt pulley h²
attached to the spindle h which carries the bobbin; b, c, is the yarn which enters
through the hollow trunnion d at the head of the flyer; and d², Fig. 1, is a short
hollow spindle having its bearing in the short hollow trunnion, and serving to
carry the central or sun wheel e.
By reference to the Drawings it will be seen that in both arrangements the
peculiar feature of this Invention is embodied, namely, the guiding pullies or eyes f
which conduct the yarn c on to the bobbins b are caused to move backwards and
forwards along the legs a¹ of the flyers a. This is done by means of the right and
left handed screws g with continuous threads on the same barrel or spindle, to
which rotary motion is communicated through gearing e¹ from a sun and planet
motion on the flyer a; the central pinion e of the sun and planet motion being
driven at a different speed from the flyer a, and the planet wheels c¹ being on the
flyer.
The right and left handed screw 9 carries the yarn guide f backwards and
forwards along the leg a¹ of the flyer a, and thereby traverses the yarn c on the
bobbin b.
A sun and planet motion in the flyer a is the usual method of actuating the
hauling pulleys shewn at e² for drawing the yarn c into the flyer a, and this same
motion I use in the arrangement shewn in Figures 1 and 2 for driving the right
and left handed screws g, which traverse the guiding pullies f.
A separate sun and planet motion may however be used. for driving the screws g,
as shewn in Figures 3 and 4, the central pinion e of this motion being attached to
the spindle that carries the bobbin b, the planet wheels e¹ being on the flyer a
as before. In this case the difference between the speeds of the bobbin 6 and

page_text: flyer a, the former of which changes its speed at the completion' of each layer of
yarn, imparts a rotary motion to the right and left handed screw g, which
necessarily changes at each layer of yarn wound upon the bobbin b; and so causes
the distance between each coil of yarn to remain always the same during the
filling of the bobbin b.
For the purpose of putting on or taking off the bobbin b, the spindle.h-which
carries it is hinged at the carrier plate h¹.
By reason of the guiding pullies or eyes f being made to travel backward and
forwards along the legs a¹ of the flyers a, instead of the bobbins b moving in the
direction of their axes inside the flyers a as at present, the legs a¹ of the flyers a
and the spindles h for supporting the bobbins b inside the flyers a require to be
made only about one half their present length, and they are consequently much
stiffer; besides this the traversing motions outside the flyers a for moving the
bobbin b are dispensed with, and so the machines are considerably simplified,
strengthened, and at the same time shortened in length.
Having now described the nature of my Invention of "Improvements in
Machinery for Spinning or Twisting Coarse Yarns," and explained the manner
of carrying the same into effect, I wish it to be understood that under the above
in part recited Letters Patent I claim traversing the yarn upon the bobbins by
means of right and left handed screws mounted in or carried by the flyer legs, such
screws being driven from a central wheel, as above described.

seal, the Fifteenth day of August, in the year of our Lord One thousand
eight hundred and eighty one.
