Year: 1877

page_text: LETTERS PATENT to James Press, of Dunmurry, in the County of Antrim, in
Ireland, Mechanic, and William Young, of same Place, Mill Manager, for the
Invention of "IMPROVEMENTS IN SPINNING MACHINERY."
PROVISIONAL SPECIFICATION left by the said James Press and William
Young at the Office of the Commissioners of Patents on the 5th November
1877.

and WILLIAM YOUNG, of same Place, Mill Manager. "IMPROVEMENTS IN SPINNING
MACHINERY."
The object of our Invention is to provide a better means for regulating the drag
or velocity of bobbins, pirns, or spools, while being filled with yarns or threads. For
this purpose we dispense with the builder rail now usually employed in spinning
and twisting frames, and we raise and lower the spindles directly in the same
manner as the builder rail is ordinarily actuated; and the bobbin, pirn, or spool
rests upon a collar attached to the end of a portion of. the spindle, which passes
through it, and is of about the same length as itself.
We dispense also with the spindle now usually employed, and we couple the
portion of a spindle, above mentioned, at the collar with a tube, which passes
through the neck or socket in the neck rail, and is connected at the lower end with
the builder shaft.
A brake to operate on the bobbin, pirn, or spool, is attached to the collar or
coupling, and a chain, wire or rod passing down through the tube connects the brake
with a lever, wheel, or weight, which is to be adjusted by the attendant.

page_text: The neck or socket in the neck rail is prolonged above the rail, and carries an
inverted flyer, which is furnished with a pulley, driven by the ordinary means, and
revolves round the bobbin, pirn, or spool, and spindle.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said James Press and William Young in the Great Seal Patent
Office on the 3rd May 1878.
JAMES PRESS, of Dunmurry, in the County of Antrim, in Ireland, Mechanic, and
WILLIAM YOUNG, of the same Place, Mill Manager. "IMPROVEMENTS IN SPINNING
MACHINERY."
This Invention relates to that class of spinning machinery in which, in place of
pendent flyers, up-turned flyers are used, the object being to provide a better
means than was hitherto available for regulating the drag or velocity of the bobbins,
pirns, or spools, while being filled with yarns or threads. To this end we mount
the bobbin or spool in a hollow support, which is fitted with a rock lever that acts
as a drag upon the bobbin, it being caused to bear upon the foot thereof by being
connected through a rod, chain, or wire (which hangs in the hollow support) with a
weighted lever, which rises and falls with the bobbin, and thus serves to maintain
the drag thereon.
In the accompanying Drawing, Fig. 1 shews, in elevation, a bobbin fitted with a
drag constructed according to our Invention; and Fig. 2 is a vertical section of the
same.
In the Figures A is the bobbin mounted on a vertical pin B made fast by solder or
otherwise to a hollow cap piece C, which forms the top of a tube D constituting the
hollow support for the bobbin. This tube D is made fast to a lifting rail E, from
which it receives a vertical motion to give the required traverse motion to the bobbin,
pirn, or spool. The cap piece C is slotted vertically through one side to receive a
rock lever F, the outer end of which is up-turned to form a brake or drag, its action
being to press against the foot of the bobbin or spool. To the inner end of this rock
lever is attached a rod G, which extends down below the tube, and is connected
at its lower end to a lever H, having its fulcrum in a bracket of the lifting rail
E, and fitted with an adjustable weight H'.
The tube D carrying the bobbin works through a collar I secured to the fixed
collar rail K, and mounted on the foot of the collar is a tubular socket L, which
carries the up-turned flyer M. The flyer receives rotary motion from a band
wheel N on its socket, and admits of being driven at a high velocity, its tendency to
vibrate while spinning the yarn, and laying it upon the bobbin, being neutralized by
the extended bearing surface provided for its socket by the collar I. The lubrication
of this surface is facilitated by forming the socket L cap-shaped at its upper end, and
turning helical grooves on the outer periphery of the collar. These grooves will lead
down the oil from the cup, and spread it over the bearing surfaces, when it will
flow down to the foot of the collar I, which forms the support for the socket L. The

page_text: vertical motion of the bobbin, derived from the tubular support D, is obtained from
the ordinary rack and pinion motion indicated in the Drawing.
In order to regulate the degree of drag on the bobbin as it increases in diameter,
the weight H is shifted on its lever by the attendant. To facilitate this adjust-
ment, the weight is carried by a swinging hooked wire set transversely of the lever,
and the lever is notched transversely to receive the suspending wire.
In order to release the bobbin from the pressure of the drag when the bobbin is
required to be doffed, the weight is shifted from one side of the fulcrum of the lever
H to the other side. This will cause the rod G to rise and rock the lever F clear of
the bobbin.
Having now set forth the nature of our Invention of "Improvements in Spinning
Machinery," and explained the manner of carrying the same into effect, we wish it
to be understood that under the above in part recited Letters Patent we claim, in
combination with an up-turned flyer, a hollow support for the bobbin, pirn, or spool,
such support being fitted with a laterally pressing brake or drag, as described, con-
nected by rod, wire, or chain with a weighted lever or its equivalent, which follows
the vertical movements of the bobbin.
In witness whereof, we, the said James Press and William Young, have here-
unto set our hands and seals, the Second day of May, in the year of our
Lord One thousand eight hundred and seventy-eight.
