Improvements relating to Spindles for Spinning and Twisting
Machines.
I, THOMAS ALEXANDER BOYD, of the Firm of J. & T. Boyd, Shettleston Iron
Works, in the County of Lanark, North Britain, Engineer do hereby declare the
nature of this Invention to be follows:-
My Invention relates to improvements in what are generally known as self-
contained ring spindles (most of which are made on the self-balancing principle) of
that kind in which each spindle is carried by two sockets, ie, an internal step tube
socket and an external oil cup pedestal socket in which when the spindle is running
the oil circulates through openings in the interual socket so as freely to lubricate its
spindle bearings. The external pedestal socket is formel with a collar to rest upon
the spindle rail and is secured to the latter by a nut screwed upon a part of the
socket projecting downwards through a hole in the rail by which it can be adjusted
so that the perpendicular axis of the spindle may be set as nearly as possible in the
exact centre of its ring during the whole traverse of the ring, which is very
important. The hole in the rail is made for this purpose a little larger than the part
of the external pedestal socket which passes through it so as to have the required
amount of adjustinent. When spindles of the kind above described require cleaning,
the usual custom is to remove the spindle and the loose internal socket and pump
the dirty oil out of the external pedestal socket. This, however, is not satisfactory
as it occupies too much time and it does not always thoroughly remove the dirty oil.
So, in many cases, in order thoroughly to cleanse the external pedestal socket it is
unscrewed and removed from the rail and emptied and washed out, but this also is
obviously objectionable as it necessitates its being carefully re-adjusted and tightened
up in the centre of its ring.
The chief object of my Invention is to overcome the above objections so as to
make the oiling and cleansing of the external oil cup socket inore convenient and
more satisfactory.
In carrying out my Invention the internal step tube socket is combined with its
external oil cup in the ordinary way and for the purpose above described and I make
the pedestal part of the socket also as described, with this exception, that instead of
making the oil cup and pedestal all in one piece as usual I make them in two separate
parts .e. a pedestal socket part which can be adjustably fixed in the usual manner to
the spindle rail by a nut, and a separate external oil cup socket part which
passes through the pedestal part and by means of a shoulder or collar on
which it rests is carried by the pedestal part; or the two parts may be made
tapered to fit one another, so that the oil cup socket part can be easily
removed therefrom for oiling. The external cup socket when made in this
improved manner, besides being more satisfactory and convenient, requires no
re-adjustment when for the purpose of cleansing or any other purpose it is taken
out and put back in its place, as it fills nicely the hole formed to receive it
in the centre of the pedestal; and owing to the length of its bearing in the latter
the spindle is held correctly in its working position without the aid or necessity of

page_text: nuts or screws of any kind. A leather washer or a pin may be used to prevent the
external cup socket turning in its pedestal socket by the action of the revolving
spindle should it be found necessary; and for this purpose a pin which may be put
in the collar of the external cup socket, is let into one of the slots on the top face of
the pedestal socket, and by putting the pin sometimes into one slot and sometimes
into the other the external cup socket is partly turned round so that a more uniform
wear and longer duration of its internal step tube socket is obtained than when the
latter is so made that it always occupies the same position in relation to its external
cup socket.
Instead of the external cup socket being made to be put into its pedestal socket
from above and with a collar to rest on the top of the latter, it may be made without
the collar so that it may be taken out and put back into its place through the bottom
end of the pedestal socket. in which case a bayonet joint, or some other device may
be used to sustain it in its working position.
My improved pedestal socket combined with its external and internal socket,
though specially designed to be used for ring spinning and twisting, can also be used
to advantage in some cases for flyer spinning and twisting machines.
In the case of flyer spindles and other spindles which for various reasons may not
require any careful central adjustment when being fixed in their working position on
their spindle rails, it is not necessary to have the holes in the spindle rails any larger
than the part of the pedestal which passes through it and in cases of this kind if the
spindle rails be made with holes deep enough, or in the case of box rails, if the top
and under holes be made far enough apart, and if these be carefully spaced to the
pitch of machine and correctly bored to fit the diameter of my improved external oil
cup socket, the latter may be used to advantage alone in combination with its
internal step tube socket as described, without the pedestal socket. The external
and internal sockets in combination may also be used with many other forms of rail
brackets. My improved pedestal socket may also be made in one piece with bracket.
like castings required for stopping spindles with or without automatic motion, similar
to what is shewn and described in the Specification of Letters Patent No. 19036
of 1889.
Another part of my present Invention relates to an improved self-acting spindle
catch of the kind described in the Specification of Letters Patent No. 18920 of 1888,
the object of which is to prevent the spindle being lifted out of its place when
doffing. My improved catch is by preference loosely jointed behind the spindle to
an upwardly projecting part of the pedestal socket and my improvement consists in
making, and arranging the catch and its details so that the operator instead of, as
formerly, requiring to use both hands, one to release the catch, and the other to lift
the spindle, can with the thumb and the finger of one hand simultaneously and
conveniently release the catch and lift the spindle out of its socket. For this purpose
and also for the purpose of giving more rooin to the building rail when down at its
lowest point, ny improved spindle catch is centred lower down than formerly, but as
in the former case it is made with a bevel by acting on which the spindle pushes it
aside when being put into its socket while a tail formed at the back of the catch acts
as a weight to return it into its catching position, as soon as the spindle is down far
enough, so as to prevent the spindle from being lifted out of its socket till the catch
is released by the hand of the operator. Instead, however, of engaging with the
upper surface of the top flange of the spindle pulley, for this purpose, my improved
catch engages with part of the top surface of the under flange of the pulley of the
spindle. The other object of my present Invention referred to is very simply
obtained by making the spindle catch with a part projecting a short distance
above the horn, or upwardly projecting part, on which it is pivoted. On this
projecting part of the catch the thumb and fore-finger of the operator can act so
as simultaneously and conveniently to release the catch and lift the spindle.

Improvements relating to Spindles for Spinning and Twisting
Machines.
I, THOMAS ALEXANDER BOYD, of the Firm of J. & T. Boyd, Shettleston Iron
Works, in the County of Lanark, Engineer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
My Invention relates to improvements in what are generally known as self-
contained ring spindles (most of which are made on the self-balancing principle) of
that kind in which each spindle is carried by two sockets, i.e. an internal step tube
socket and an external oil cup pedestal socket in which when the spindle is running
the oil circulates through openings in the internal socket so as freely to lubricate its
spindle bearings. The external pedestal socket is formed with a collar to rest upon
the spindle rail and is secured to the latter by a nut screwed upon a part of the
socket projecting downwards through a hole in the rail by which it can be adjusted
so that the perpendicular axis of the spindle may be set as nearly as possible in the
exact centre of its ring during the whole traverse of the ring, which is very
important. The hole in the rail is made for this purpose a little larger than the part
of the external pedestal socket which passes through it so as to provide for the
required amount of aljustment. When spindles of the kind above described require
cleaning, the usual custom is to remove the spindle and the loose internal socket and
pump the dirty oil out of the external pedestal socket. This, however, is not
satisfactory as it occupies too much time and it does not always thoroughly remove
the dirty oil. So, in many cases, in order thoroughly to cleanse the external pedestal
socket it is unscrewed and removed from the rail and emptied and washed out, but
this also is obviously objectionable as it necessitates its being carefully re-adjusted
and tightened up in the centre of its ring.
The chief object of my Invention is to overcome the above objections so as to
make the oiling and cleansing of the external oil cup socket more convenient
and more satisfactory. My present improvements are shown in an accompanying
sheet of drawings and are herein-after described with reference to said drawings.
Figure 1 is a side elevation of the improved spindle shewing in section the part of
a spindle rail in which the spindle is adjustably fixed.
Figure 2 is a sectional view of same.
Figure 3 is a plan view of the spindle pedestal.
Figures 4, 5 and 6 are a front view, side view and plan.
Figures 7, 8 and 9 are front, side and plan views of other applications of my
present improvements referred to.
Similar numbers of reference designate corresponding parts throughout.
In carrying out my Invention the internal step tube socket 11, Figures 1 and 2, is
combined with its external oil cup 12 in the ordinary way and for the purpose above
described and I make the pedestal part of the socket 13 also as described, with this
exception, that instead of making the oil cup and pedestal all in one piece as usual
I make them in two separate parts i.e. a pedestal socket part 13 which can he
adjustably fixed in the usual manner to the spindle rail 14, by a nut 15, and a
separate external oil cup socket part 12 which passes through the pedestal part and
by means of a shoulder or collar 16 on which it rests is carried by the pedestal
part 13; or the two parts may be made tapered to fit one another, so that the oil
cup socket part can be easily removed therefrom for oiling. The external cup
socket 12 when made in this improved manner, besides being more satisfactory and
convenient, requires no re-adjustment when for the purpose of cleansing or any other

page_text: purpose it is taken out and put back in its place, as it fills nicely the hole formed to
receive it in the centre of the pedestal 13; and owing to the length of its bearing
in the latter the spindle 17 is held correctly in its working position without the aid
or necessity of nuts or screws. A leather washer or a pin may be used to prevent the
external cup socket 12 turning in its pedestal socket 13 by the action of the revolving
spindle 17 should it be found necessary; and for this purpose, a pin 18 which may
be put in the projecting part 24, of the pedestal socket 13, is let into the slot 19
Figure 1 on the external cup socket 12.
My improved pedestal socket combined with its external and internal socket,
though specially designed to be used for ring spinning and twisting, can also be used
to advantage in some cases for flyer spinning and twisting machines.
In the case of flyer spindles and other spindles which for various reasons may not
require any careful central adjustinent when being fixed in their working position on
their spindle rails, it is not necessary to have the holes in the spindle rails any larger
than the part of the pedestal which passes through it and in cases of this kind if
the spindle rails 21, Figures 4, 5 and 6 be made with holes deep enough, or in the
case of box rails 22, Figures 7, 8 and 9, if the top and under holes be made far
enough apart, and if these be carefully spaced to the pitch of machine and correctly
bored to fit the diameter of iny improved external oil cup socket 12, the latter may
be used to advantage alone in combination with its internal step tube socket 11, as
described, without the pedestal socket 13. The external and internal sockets 11
and 12 in combination may also be used with many other forms of rail brackets. My
improved pedestal socket inay also be made in one piece with bracket like castings
required for stopping spindles with or without automatic motion, similar to what is
shewn and described in the Specification of Letters Patent No. 19036 of 1889.
Another part of my present Invention relates to an improved self-acting spindle
catch 23 of the kind described in the Specification of Letters Patent No. 18920
of 1888, the object of which is to prevent the spindle 17 being lifted out of its place
when doffing. My improved catch is by preference loosely jointed behind the spindle
to an upwardly projecting part 24 of the pedestal socket 13 and my improvement
consists in making, and arranging the catch 23 and its details so that the operator
instead of, as formerly, requiring to use both hands, one to release the catch, and the
other to lift the spindle, can with the thunb and the finger of one hand
simultaneously and conveniently release the catch 23 and lift the spindle 17 out of
its socket. For this purpose and also for the purpose of giving more room to the
building rail when down at its lowest point, my improved spindle catch 23 is centred
lower down than formerly, but as in the former case it is made with a bevel 25 by
acting on which the spindle 17 pushes it aside when being put into its socket 11;
while a tail 26 formed at the back of the catch acts as a weight to return it into its
catching position, as shewn in the drawings, as soon as the spindle is down far
enough, so as to prevent the spindle from being lifted out of its socket till the catch
is released by the hand of the operator. Instead, however, of engaging with the
upper surface of the top flange 27 of the spindle pulley, for this purpose, my
improved catch engages with part of the top surface 28 of the under flange of the
pulley of the spindle.
The other object of my present Invention referred to is very simply obtained by
making the spindle catch 23 with the part 29 projecting a short distance above the
horn, or upwardly projecting part 24, on which it is pivoted. On this projecting
part 29 of the catch the thumb and fore-finger of the operator can act so as
simultaneously and conveniently to release the catch 23 and lift the spindle 17.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is
1. The combination of an internal step tube socket 11 and an external removable
oil cup socket 12 arranged substantially as and for the purposes herein before described
with reference to Figures 1 to 9 of accompanying drawings.

page_text: 2. The combination of an internal step tube socket 11, an external removable oil
cup socket 12, and a pedestal socket 13 which latter can be adjusted and fixed
permanently to a spindle rail substantially as and for the purposes hereinbefore
described with reference to Figures 1 to 3 of accompanying drawings.
3. The improved beveled self-acting spindle catch 23 constructed and arranged to
operate substantially as and for the purposes herein before described with reference
to Figures 1 to 3 of accompanying drawings.
