IMPROVE- MENTS IN SPINNING AND IN APPARATUS CONNECTED THEREWITH."
Year: 1876

page_text: LETTERS PATENT to Benjamin Berry, Machine Maker, Sidney Emsley, Agent,
both of Bradford, in the County of York, and Samuel Smith, of Low Bridge
Works, Keighley, in the aforesaid County, for the Invention of "IMPROVE-
MENTS IN SPINNING AND IN APPARATUS CONNECTED THEREWITH."
PROVISIONAL SPECIFICATION left by the said Benjamin Berry, Sidney
Emsley, and Samuel Smith at the Office of the Commissioners of Patents on
the 28th January 1876.

the County of York, and SAMUEL SMITH, of Low Bridge Works, Keighley, in the
aforesaid County.
"IMPROVEMENTS IN SPINNING AND IN APPARATUS CONNECTED
THEREWITH."
Our improvements relate to preventing untwisted draughted roving from being
blown or attracted to the adjoining draughted rovings being_twisted into yarn as
they leave the drawing, draughting, or delivery rollers. For this purpose we fix
under the spinning frame or on the side a fan or blower having a main pipe con-
nected to a pipe or tube running the length of the frame; on this pipe or tube are
fixed flat conical curved air conductors which are fitted behind and under each
draughting roller producing a sufficient gust of wind to lift and convey the draughted
roving to the front top pressing, draughting, delivery rollers, there to be unrolled
and formed into roller laps during the time the operator is occupied elsewhere; or
we fix a fan or blower in a room, or in any suitable place, having a main pipe
feeding the air conductors of the spinning machines in a room or rooms. By these
means we prevent the waste of material heretofore made, for in the machines in
ordinary use when the draughted roving ceases its continuity in being spun the
untwisted material or fibres are subject to being blown or attached to the adjoining
spinning threads by the current of air produced by the rapid rotatry motion of
the spindles and flyers above and below the guide board, causing entangled yarn
made from two or more rollers which has to be pulled back from the bobbins, pro-
ducing waste of less value than roller laps.

the said Benjamin Berry, Sidney Emsley, and Samuel Smith in the Great Seal
Patent Office on the 24th July 1876.
BENJAMIN BERRY, Machine Maker, SIDNEY EMSLEY, Agent, both of Bradford, in
the County of York, and SAMUEL SMITH, of Low Bridge Works, Keighley, in the
County aforesaid. "IMPROVEMENTS IN SPINNING AND IN APPARATUS CONNECTED
THEREWITH."
The said Invention relates to preventing untwisted draughted roving from being
blown or attracted to the adjoining draughted rovings being twisted into yarn as
they leave the drawing, draughting, or delivery rollers. For this purpose we fix
under the spinning frame or on the side a fan or blower, having a main pipe con-
nected to an air conductor, pipe, or tube running the length of the frame; in the
top of the air conductor, pipe, or tube, are formed openings under each draughting
roller, producing a sufficient gust of wind to lift and convey the draughted roving
to the front top pressing, draughting, delivery rollers, there to be rolled and formed
into roller laps during the time the operator is occupied elsewhere; or we fix a fan
or blower in a room, or in any suitable place, having a main pipe feeding the air
conductors of the spinning machines in a room or rooms. By these means we pre-
vent the waste of material heretofore made, for in the machines in ordinary use
when the draughted roving ceases its continuity in being spun the untwisted
material or fibres are subject to being blown or attached to the adjoining spinning
threads by the current of air produced by the rapid rotatory motion of the spindles
and flyers above and below the guide board, causing entangled yarn to be made
from two or more rollers, and which has to be pulled back from the bobbins, pro-
ducing waste of less value than roller laps.
But in order to enable our improvements to be better understood we will proceed
to describe the same by reference to the accompanying Drawing, in which Figure 1
represents a side view of the. blowing apparatus, and Figure 2 front elevation of
the same.
Similar letters of reference are used to represent similar parts.
Under the spinning frame A, or on the side we fix a fan B (or a blower), having
a main pipe C, connected to an air chamber D, running the length of the frame;
in the top of the chamber and under each of the draughting rollers E and F
are formed openings G, and between each of these openings are fitted plates H for
the purpose of guiding the currents of air in upward directions, producing a suf-
ficient gust of wind to lift and convey the draughted roving I to the front top
pressing, draughting, delivery roller F, there to be rolled and formed into roller laps
during the time the operative is occupied elsewhere. The drawing only shews the
apparatus fitted to one side of a spinning frame, but a similarly constructed air
chamber is fitted on the other side of the spinning frame, and a branch pipe is fixed
to the main pipe C, the fan is actuated by a pulley J and belt K, the pulley is fitted
on the shaft of the driving drum L; the guide board M is fitted on hinges fixed to
the top of the air conductor or chamber D, or we fix a fan or blower in a room, or
in any suitable place, having a main pipe feeding the air conductor D of the spinning
machines in a room or rooms. By these means we prevent the waste of material
heretofore made, for in the machines in ordinary use when the draughted roving
ecases its continuity in being spun, the untwisted material or fibres are subject to
being blown or attached to the adjoining spinning threads by the current of air
produced by the rapid rotatory motion of the spindles N and flyers O above and
below the guide board M, causing entangled yarn to be made from two or more
rollers F, and which has to be pulled back from the bobbins, producing waste of
less value than roller laps.
Having thus described our improvements, and the best means we are acquainted
with for carrying the same into effect, we would have it understood that we do not
confine ourselves to the precise details shewn and described as these may be varied
without departing from the peculiar character of the Invention, but what we do

page_text: claim is, the method of and construction and employment of apparatus for produc-
ing a blast of wind, lifting and conveying the draughted rovings to the front top
pressing, draughting, delivery rollers, there to be rolled and formed into roller laps;
preventing untwisted draughted rovings from being blown or attached to the
adjoining draughted rovings, which are being twisted into yarn as they leave the
drawing, draughting, or delivery rollers, substantially as herein-before described and
represented in the accompanying Drawing.
In witness whereof I, the said Sidney Emsley, for and on behalf of myself and
the said Benjamin Berry and Samuel Smith, have hereto set my hand and
seal, this Twenty-second day of July, in the year of our Lord One thousand
eight hundred and seventy-six.
Witness,
