IMPROVEMENTS IN MACHINERY FOR SPINNING SILK AND OTHER FIBROUS MATERIAL
Year: 1884

page_text: I HENRY EDWARD NEWTON of the Office for Patents Breams Buildings
Chancery Lane in the County of Middlesex Civil Engineer do hereby declare the
nature of my Invention for "IMPROVEMENTS IN MACHINERY FOR SPINNING SILK
AND OTHER FIBROUS MATERIAL," and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
When the spindle-driving bands of spinning frames are too slack there is a
slackness in the twist of the yarn or thread and when the bands are too tight there
is unnecessary friction which requires more power to drive the spindles and
involves greater wear upon the spindles, spindle bearings and bands.
The object of one part of this Invention is to obtain an automatic regulation on
the tension of the bands whereby any stretching and any such variation in length
as may result from variations of weather may be compensated for, and such a.
degree of tension as will ensure the best results may be uniformly preserved.
The object of another part of my Invention which applies only to spindles which
give the twist to the yarn or thread as it passes off from them as is common in
spinning silk is to break the thread or yarn automatically in case of the breaking
of the band and to thus prevent à quantity of untwisted thread or yarn from being
taken off the spindle after its rotation censes.
The Invention consists in the combination with a spindle rail, a spindle and its
driving band and a spindle step and bolster, of a spindle base in which said step
and bolster are mounted and which is so supported from the rail that it is capable
of movement to carry the spindle towards and from the rail and means consisting
of a spring or a weight acting upon the spindle base to impel it and the spindle
away from the rail and serving to maintain a proper tension of the driving band.
The power of the spring or weight acts in the opposite direction to the tension of
the spindle driving band and the spring or weight is so proportioned that it will
preserve the proper tension on the band.

page_text: In order to support the spindle base so that it will be capable of automatic
movement as above described it may be hinged by a vertical pivot to the spindle
rail or to a bracket projecting therefrom and the spring may be coiled around said
pivot and have one end bearing on the base and the other on the bracket. This
construction also forms a part of this Invention.
To the end that the yarn or thread being spun off a spindle so supported may be
broken when the spindle band breaks this Invention consists in the combination
with the above described movable spindle base, spindle step and bolster, spindle
and spring or weight, of an abutment against which a bobbin placed on the spindle
will be carried when the spindle moves outward at the breaking of the band, and
between which and the bobbin the yarn or thread will catch as it is unwound.from
the bobbins and so to be broken off by the combined rotation of the spool upon
which it is being taken up from the spindle.
The Invention also consists in certain details of construction hereinafter described
and claimed.
In the accompanying Drawing Fig. 1 represents a transverse section of a spindle
rail and an elevation of a spindle supported according to this Invention, and an
abutment against which the bobbin may strike. Figure 2 represents a plan of
said parts; Figure 3 represents a horizontal section in the line x x Figure 1.
Figure 4 is an elevation of the spindle base detached from the other parts;
Figure 5 is a plan of the spindle base.
Similar letters of reference designate corresponding parts in all the Figures.
In carrying out, this Invention the spindle rail may be of ordinary or any
suitable form.
In the example represented it is composed of two parallel hollow rods or
tubes A. A.
B B¹ designate clamps, or clamping pieces which are applied to opposite sides of
the two rods or tubes A and secured thereon by a screw or bolt a passing between
the rods or tubes. The clamp or clamping piece B¹ has projecting from it a
bracket B2 the purpose of which will be presently explained.
C designates a spindle on' which is a bobbin D and the whirl C¹ which receives
the driving band. C².
The driving pulleys or drums for the bands are not shown as they form no part
of this Invention but they may be of any known or suitable kind.
E designates the piece which constitutes the spindle step and bolster and
F designates a spindle base in which the step and bolster piece F is mounted.
The spindle here shown is what is termed a gravitating spindle its step and bolster
piece E having a yielding or flexible connection with the spindle base provided by
the spring E between the nut E2 and the base. This construction however forms
no part of this Invention nor is it absolutely necessary to its success but the
Invention is applicable to a spindle having its step and bolster rigidly mounted in
the spindle base F.
To carry out the Invention the spindle base F must be so supported by the
rail A A that it shall be capable of movement to carry the spindle towards and
from the rail. In this example of the Invention this desired result is attained by 4
hinging the base by a vertical pivot c to the bracket B2. The base can then swing
horizontally from a position shown in full lines in Figure 2 and even further
towards the rail A to the position shown in dotted lines in said Figure.
G designates a spring which is coiled around the pivot c and the ends of which
bear; one on the bracket B and the other on the step and bolster piece E and 5
through the latter acting on the spindle base F and spindle. This spring G exerts
a constant tendency to move or swing the base F outwards and so move the
spindle C away from the rail A. A but the driving band C2 holds the spindle and
base against swinging outwards beyond its limit. The spring G keeps the band
constantly under a uniform tension which will counteract aby tendency to slackness 5

page_text: and by properly proportioning the force of the spring a proper tension on the
band C will always be maintained.
A properly proportioned weight might be applied to the base F in lieu of and as
an equivalent to the spring G.
It will be understood that in case of the breakage of the driving band C³, the
spring G, or its equivalent weight is relieved of any resistance and will at once
swing the base and spindle outwards. Under ordinary circumstances the yarn or
thread would continue to be unwound from the bobbin D in an untwisted state.
To prevent this I provide an abutment H against which the bobbin on any one of
the spindles in the machine will strike when the corresponding spindle is allowed.
to move outwards, and in unwinding, the yarns or thread d will surely be caught
between the bobbin and this abutment and at once be broken off.
The abutment shown consists of a rail H extending along the front of the
machine and supported by standards. H' from the rail A. The standards H¹ may
be fastened to the rods or tubes A by means of clamps similar to the clamps B B¹
or they may be fastened in any other suitable manner.
In lieu of employing the bracket B2 the spindle base F may be pivotted directly
to the spindle rail if the latter be of usual construction.
By this Invention provision is made for keeping a uniform and proper tension
upon the band C2 and no considerable quantity of yarn or thread can be taken
from the bobbins D in an untwisted condition while the bobbin is at rest.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is
1st The combination with a spindle rail, a spindle and its driving band and a
spindle step and bolster of a spindle base in which said step and bolster are
mounted and which is supported from the rail substantially as specified whereby it
is capable of movement to carry the spindle towards and from the rail and means
acting upon the spindle base to impel it and the spindle away from the rail and
serving to maintain a proper tension on the driving band substantially as herein
described.
2nd The combination with a spindle rail a spindle and its driving band and a
spindle step and bolster of a spindle base in which said step and bolster are
mounted which is supported from the rail and which is mounted on a vertical
pivot as described so as to swing horizontally towards and from said rail and
means for impelling said base automatically away from the rail and serving to
maintain a proper tension on the driving band, substantially as herein described.
3rd The combination with a spindle rail and a bracket projecting therefrom of
the base F and the vertical pivot c connecting said base with said bracket the
spring G coiled around said pivot and bearing with its ends against said bracket
and base the step and bolster E carried by said base and the spindle C in said step
and bolster, substantially as herein described.

abutment against which a bobbin on the spindle will be carried by the outward
movement of said spindle and between which and the bobbin the yarn or thread
will be caught in unwinding and so broken off substantially as and for the purpose
described.
