IMPROVEMENTS IN SPINNING FRAMES
Year: 1877

page_text: LETTERS PATENT to William Ireland, of Buckhaven, in the County of Fife,
North Britain, Manufacturer, for the Invention of "IMPROVEMENTS IN SPINNING
FRAMES"
Sealed the 19th February 1878, and dated the 25th August 1877.
PROVISIONAL SPECIFICATION left by the said William Ireland at the Office
of the Commissioners of Patents on the 25th August 1877.
WILLIAM IRELAND, of Buckhaven, in the County of Fife, North Britain, Manu-
facturer. "IMPROVEMENTS IN SPINNING FRAMES."
This Invention, which relates to improvements in spinning frames, has for its
object to prevent the grooving of the wooden rollers commonly known as "pressing
rollers," or those by which the sliver or rove is forced against the drawing
rollers.
The Invention also has for its object to maintain the true cylindrical surface of
the pressing rollers, to economise the material at present wasted in narrowing down'
the exterior portion of their width, and to dispense as much as possible with the
cost and necessity of filing or turning out the grooves.
Also, to avoid the stopping of portions of the frame, which at present so frequently
occurs when the pressing rollers have to be removed.
The Invention consists in keeping the pressing rollers of greater width at their
circumference than at present, and in connecting the conductor, either to the spindle
whereon the drawing rollers are carried, or to any equivalently moving part of the
spinning frame, so that a horizontal reciprocating motion is imparted to the con-
ductors to an extent corresponding with the motion of the drawing rollers.
In cases where the drawing rollers are not reciprocated, the conductors are moved
horizontally from any convenient lever, camb, or other oscillating part of the
spinning frame. This independent reciprocating motion may also be used when
the drawing rollers are reciprocated, in which case the conductors move, at a,
different rate or direction, opposite to that in which the drawing rollers are
reciprocated.

page_text: Under this Invention, pressing rollers made of iron or other material, covered
with leather or a like substance, may be used.
The effect of the reciprocating motion of the conductors is to shift the sliver or
rove at all times to different points of contact with the pressing and drawing
rollers.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Ireland in the Great Seal Patent Office on the 23rd February
1878.
WILLIAM IRELAND, of Buckhaven, in the County of Fife, North Britain, Manu-
facturer. "IMPROVEMENTS IN SPINNING FRAMES."
My said Invention relates to improvements in spinning franes, and has for its
objects to prevent the grooving of those rollers (commonly known as the "pressing
rollers"), by which the sliver or rove is forced against the drawing rollers, and
thereby to maintain the true cylindrical surface of the "pressing rollers."
-
To economise the material at present wasted in narrowing down the exterior
portion of their width, and so to dispense as much as possible with the necessity
of filing or turning out the grooves.
Also, to avoid the stopping of the spindles, which at present so frequently occurs
when the "pressing rollers" have to be removed.
These objects I effect by making the pressing rollers of greater width at their cir
cumference, and imparting a horizontal reciprocating motion to the drawing rollers.
and conductors, the motion being derived from any convenient part of the spinning
frame. The effect of this reciprocating motion of the drawing rollers and con-
ductors is to constantly shift the sliver or rove- to different points of contact with
the cylindrical surface of the "pressing rollers," and thus prevent the grooving of
the "pressing rollers."
And in order that my said Invention may be properly understood, I now proceed
more particularly to describe a system, mode, or manner in or under which the same.
is or may be used or practically carried into effect, reference being had to the
annexed Sheet of Drawings, and to the letters and figures marked thereon, that is.
to say :-
Figure 1 represents a side elevation of a portion of a spinning frame with
mechanism attached, by which my Invention may be carried into effect; and
Figure 2 is a plan of the same.
Upon a fulcrum a projecting from a bracket B bolted to the frame of the spinning
frame, turns a lever A, carrying at the end of one of its arms A¹² a friction roller
or disc a¹, in contact at either side with two of the drawing rollers C, C, fixed upon
the drawing roller shaft c. The conductors E are suspended upon the conductor
rod F, and are each formed with two ears or projecting pieces e, e, which rest against
the sides of the drawing rollers C.
The "pressing rollers" D, D, (which are of wood) are formed broader at their
circumference than are the ordinary "pressing rollers," as seen clearly in Figure 2,
that is to say, they are not narrowed down at the edges as is the case with ordinary
pressing rollers.
"

page_text: A horizontal reciprocating motion is imparted to the drawing rollers, and to
the conductors resting against them, by the arrangement now to be described. In
bearings in the brackets B is carried a shaft or spindle G, having formed or keyed
thereon a worm or tangent screw g. Upon the said shaft is also keyed a ratchet
wheel g', and a lever H is free to turn upon the said shaft, the said lever carrying a
pawl I. A worm or tangent wheel J is mounted upon a centre or axis j carried by
the bracket B, the said worm wheel having formed upon its face a heart cam ¹.
Upon the arm A² of the lever A are carried two antifriction rollers a², a², which
bear upon the face of the cam 31 at opposite sides thereof. The lever H is connected
by the rod h with the "bobbin traverse motion" of the spinning frame by which
a slow reciprocating motion is imparted to the said lever H, and the pawl I thereon
is caused to engage during its upward movement with the teeth of the ratchet
wheel g', whereby the shaft G and worm or tangent screw g are slowly rotated,
the worm or tangent screw g imparting a slow rotatory motion to the worm wheel J
and cam j', which, rotating between the antifriction rollers a², a², on the arm A³ of
the lever A, gives to the said lever a very slow reciprocating motion, which causes
the antifriction roller or disc a¹ to alternately press against one and the other of
the drawing rollers C, between which it is situated, and thus the drawing roller,
spindle c, together with all the drawing rollers carried thereon, receive a horizontal
reciprocating motion. The drawing rollers having the ears e of the conductors E
resting on their sides as shewn, the conductors are also caused to partake of the
said horizontal reciprocating motion. This motion is only of such extent as that
the drawing rollers and conductors will never move beyond the sides of circum-
ferential surface of the "pressing rollers," so that the sliver or rove may always be
kept in the position required between the driving and "pressing rollers."
Having now described and particularly ascertained the nature of my said Inven-
tion, and the system, mode, or manner in or under which the same is or may be
used or practically carried into effect, I would observe in conclusion that I do not
limit myself to obtaining the horizontal reciprocating motion of the drawing rollers
and conductors from the "bobbin traverse motion," as it may be obtained from any
other convenient part of the mechanism of the spinning frame; I however find it
in practice that the obtainment of the reciprocating motion from the "bobbin
traverse motion" is an arrangement which works well; what I therefore consider
to be novel and original, and claim as the Invention secured to me by the herein-
before in part recited Letters Patent is, imparting to the drawing rollers and con-
ductors of spinning frames a horizontal reciprocating motion, so as to shift the
sliver or rove to different points of contact with the "pressing rollers" by mechanism
acting substantially as herein-before described, and for the purposes set forth.
In witness whereof, I, the said William Ireland, have hereunto set my hand
and seal, this Twenty-first day of February, in the year of our Lord
One thousand eight hundred and seventy-eight.
WILLIAM IRELAND. (L.S.)
