Improvements relating to Bolster Bearings for the Spindles of Roving,
Slubbing, and like Frames for Preparing Fibrous Materials.
We, TAYLOR, LANG & Co. LIMITED, of Castle Iron Works, Stalybridge, in
the County of Chester, Machine Makers and Ironfounders, and WILLIAM THOMAS
WATTS, of the same place, Director of the said Company, do hereby declare the
nature of the said invention, to be as follows: :-
Our invention relates to a combination, arrangement and construction of
mechanism or devices for holding and securing the tube bolster bearing of
roving, slubbing and like machines in such manner that they can be held true,
and can be adjusted to the spindle to leave it perfectly free to rotate, and so
that the bearing will not (as in the ordinary mode of construction) bind upon
the spindle in any way for want of exact truth in the line of the tube bearing
in relation to the spindle.
According to our invention, the bolster rail is a straight bar planed on its
opposite sides to a uniform thickness, and holes are bored in it, one for each
spindle, across the rail and at a right angle to its lengthway. In each hole the
shank of what we will term a tubular "cradle" holder fits, the shoulder on the
cradle holder coming against one side of the rail while the shank extends nearly
through the hole in the rail.
The cradle holder has at its outer end a semi-circular cavity, to fit the exterior
diameter of the tubular bolster bearing for the spindle, the axis of this semi-
circular cavity being in a line at a right angle to the axis of the lengthway of
the cradle holder in a line with the axis of the spindle when in its position
in the tubular bearing.
The tubular bearing passes through the eye of a bolt, the eye being bored
out to an easy fit for the exterior of the tube bearing to pass through, the
collar upon it resting against the upper side of the cradle. The stem of the
eye bolt passes through the bore in the lengthway of the cradle, there being a
sufficient space or cavity in the cradle for the eye bolt head to be drawn into
without coming against it. A washer is put on the end of the stem of the eye
bolt which projects through the end of the shank of the cradle and it is screwed
up firmly by a screw nut and secured by a lock nut when the spindle is in
position in its bearing in the tube. This arrangement permits the cradle to be
turned to adjust the tube bearing held by it to the spindle.
By a modification of our invention the carrier of the tube bearing is arranged
to swivel in a hole in the rail as above described, and is secured thereto by a
bolt or by a set screw by preference.
This carrier is secured in the rail as described, and is bored out to receive
the exterior of the tube bearing and it is slit so that the slit portions can be
drawn together by a set screw so as to grip the exterior of the tube bearing and
hold it firmly. This permits of the tube bearing to be swivelled and adjusted
to suit the spindle in one direction.
Another modification is similar to that last described, but in this case the

page_text: carrier is made in two parts one to swivel in the hole in the rail and to be
secured thereto by a set screw as above described, and the other part which
is bored out to the exterior of the tube bearing and slit so that the slit parts
may be drawn together to grip the exterior of the tube bearing by a set screw,
is secured to the other part in the rail by a bolt or screw, the axis of which is
parallel to the length way of the rail, this arrangement thus allowing the
tube bearing to be adjusted to the spindle in two directions one at a right angle
to the other. Or by another modification the exterior of the tube bearing
may be formed partly spherical and to fit the holder so that when combined with
the eye bolt it may form a ball and socket to permit the tube bearing to be
adjusted to the spindle in any direction.

Improvements relating to Bolster Bearings for the Spindles of Roving,
Slubbing, and like Frames for Preparing Fibrous Materials.
We, TAYLOR, LANG & CO LIMITED, of Castle Iron Works, Stalybridge, in
the County of Chester, Machine Makers and Ironfounders, and WILLIAM THOMAS
WATTS, of the same place, Director of the said Company, 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:-
Our invention relates to a combination, arrangement and construction of
mechanism or devices for holding and securing the tube bolster bearing of
roving, slubbing and like machines in such manner that they can be held true,
and can be adjusted to the spindle to leave it perfectly free to rotate, and so
that the bearing will not (as in the ordinary mode of construction) bind upon
the spindle in any way for want of exact truth in the line of the tube bearing
in relation to the spindle
According to our invention, the bolster rail is a straight bar planed on its
opposite sides to a uniform thickness, and holes are bored in it, one for each
spindle, across the rail and at a right angle to its lengthway. In each hole the
shank of what we will term a tubular cradle holder fits, the shoulder on the
cradle holder coming against one side of the rail while the shank extends nearly
through the hole in the rail.
The cradle holder has at its outer end a semi-circular cavity, to fit the exterior
diameter of the tubular bolster bearing for the spindle, the axis of this semi-
circular cavity being in a line at a right angle to the axis of the lengthway of
the cradle holder in a line with the axis of the spindle when in its position
in the tubular bearing.
The tubular bearing passes through the eye of a bolt, the eye being bored
out to an easy fit for the exterior of the tube bearing to pass through, the

eye bolt passes through the bore in the lengthway of the cradle, there being a
sufficient space or cavity in the cradle for the eye bolt head to be drawn into
without coming against it. A washer is put on the end of the stem of the eye
bolt which projects through the end of the shank of the cradle and it is screwed
up firmly by a screw nut and secured by a lock nut when the spindle is in
position in its bearing in the tube. This arrangement permits the cradle to be
turned to adjust the tube bearing held by it to the spindle.

page_text: By a modification of our invention the carrier of the tube bearing is arranged
to swivel in a hole in the rail as above described, and is secured thereto by a
bolt or by a set screw by preference.
This carrier is secured in the rail as described, and is bored out to receive
the exterior of the tube bearing and it is slit so that the slit portions can be
drawn together by a set screw so as to grip the exterior of the tube bearing and
hold it firmly. This permits of the tube bearing to be swivelled and adjusted
to suit the spindle in one direction.
Another modification is similar to that last described but in this case the
carrier is made in two parts one to swivel in the hole in the rail and to be
secured thereto by a set screw as above described, and the other part which
is bored out to the exterior of the tube bearing and slit so that the slit parts
may be drawn together to grip the exterior of the tube bearing by
a set screw,
is secured to the other part in the rail by a bolt or screw, the axis of which is
parallel to the lengthway of the rail, this arrangement thus allowing the
tube bearing to be adjusted to the spindle in two directions one at a right angle
to the other. Or by another modification the exterior of the tube bearing
may be formed partly spherical and to fit the holder so that when combined with
the eye bolt it may form a ball and socket to permit the tube bearing to be
adjusted to the spindle in any direction.
Fig. 1, 3, 5, 7, 9 and 11 are plan views looking downwards on the upper
edge of the bolster rail, which is shown in each case in section except Fig. 11
where the rail is shown in plan.
Figs. 2, 4, 6, 8, 10 and 12 are elevations in which part of the bolster rail
is in each case shown in section.
In each of the modifications a, is the bolster rail; a¹, holes in it for the
carrier b, which has a shoulder b', to come against the rail a, and in each case
there is a washer e', for the screw nuts e², to act against.
In the modification illustrated by Figs. I and 2, the holder b, forms a cradle
to receive the bolster bearing tube d, which passes through the eye in a bolt e,
the shank of which bolt passes through a hole in the holder and is secured by
the washer e and screw nuts c².
There is space enough in the holder to allow the eye part of the bolt to enter
to allow it to draw the bolster against the cradle formed on the holder.
In the modification illustrated by Figs. 3 and 4.
The holder b, is bored out
to receive the bolster bearing d, and it is slit so as to be held tight within the
holder by the set screw 3. The holder in this case is secured to the rail a, by
a bolt e, which passes through the hole in the axis of the holder until its head
comes into a cavity in the holder.
In the modification illustrated by Figs. 5 and 6, the arrangement is the
same as that shown by Figs. 4 and 5 except that the holder where it receives
the bolster bearing d, is slit in a line with the axis of the holder, so as to grip
the bolster bearing d, and a screw e, is cast or screwed firmly into a hole in
the axis of the holder b, for the screw washer e¹, and screw nuts e².
In the modifications illustrated by Figs. 7 and S and Figs. 9 and 10, the
holder is made in two parts and *, one jointed to the other by a bolt 64, as
in Figs. 7 and 8, or a set screw 64, as in Figs. 9 and 10, the axes of which
bolt or set screw are horizontal. That part of the holder b, is or may be secured
to the rail a, in each case by a set screw e, screwing into a screw tapped hole
in the holder b.
This arrangement allows the holder b, to be swivelled in the hole in the
raila, and the other part 6, of the holder to be swivelled on the axis of the bolt
or screw 6, vertically, and secured when adjusted.
In the modification illustrated by Figs. 11 and 12, there is a holder b, having
a cradle in its end for the bolster bearing d. The exterior &, of the bolster
bearing opposite the cradle is formed partly spherical to fit a spherical cavity
in the cradle or holder and it passes through the eye of a bolt e, arranged and

page_text: secured as in the modification illustrated by Figs. 1 and 2. Thus the position
of the bolster bearing d, can be adjusted to the spindle.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
The combination of the bolster rail of roving, slubbing and like frames with
a holder and bolster bearing for the spindle substantially as and for the pur-
pose hereinbefore described and illustrated by Figs. 1 and 2; Figs. 3 and 4;
Figs. 5 and 6; Figs. 7 and 8; Figs. 9 and 10 and Figs. 11 and 12 of the
drawings.
