I WILLIAM TATHAM of Vulcan Works, Rochdale, in the County of Lancaster,
Machine Maker, do hereby declare the nature of the said invention for
"IMPROVEMENTS IN OR APPLICABLE TO MACHINES FOR SLUBBING AND ROVING
FIBROUS MATERIALS," to be as follows:-
•
My invention relates to the collar bearings of slubbing and roving frames, and
to the mode of constructing and fixing the same in the beams or rails or parts
from the beams or rails for carrying the same.
The parts in the beams or rails are accurately bored out to a definate size and
that part of each collar which is to enter the hole bored out in the rail or part
from the rail, is turned a little too large to enter the hole and then one or more
slits are made lengthway or in an helical direction for a portion of the length of
the collar to allow such part of it to be compressed to such extent as to enter
the hole bored out in the rail or part from the rail.
The elasticity of the metal of the collar when inserted in the hole thus holds it
with sufficient firmness without a screw or other mode of securing.
A modification of my invention consists in preparing the collars and holes for
them in the rails or parts from the rails as above described except that the
collar is left solid and is not slit, and one or more slits is made instead in the part
from the rail (such part being shaped and made of the desired strength) to give it
elasticity so that when the solid collar is forced into the hole in the rail the slit
or slits and form of the part permit it to give way and the elasticity of the metal
acts to grip the exterior of the collar and hold it with sufficient firmness.
The end of the collar is or may be slightly tapered or the entrance to the hole
slightly coned, and each collar is or may be gradually forced into the hole for it,
by a screw tool which may pass through the collar and screw into a nut or part
taking hold below the part in the rail for carrying the collar.

I WILLIAM TATHAM of Vulcan Works Rochdale, in the County of Lancaster,
Machine Makér, 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 the collar bearings of slubbing and roving frames, and
to the mode of constructing and fixing the same in the beams or rails or parts
from the beams or rails for carrying the same.
The parts in the beams or rails are accurately bored out to a definate size and
that part of each collar which is to enter the hole bored out in the rail or part
from the rail, is turned a little too large to enter the hole and then one or more
slits are made lengthway or in an helical direction for a portion of the length of
the collar to allow such part of it to be compressed to such extent as to enter the
hole bored out in the rail or part from the rail.
1.
The elasticity of the metal of the collar when inserted in the hole thus holds it
with sufficient firmness without a 'screw' or other mode of securing...
7.
A modification of my invention consists in preparing the collars and holes for
them in the rails or parts from the rails as above described, except that the collar
is left solid and is not slit and one or more slits is made instead in the part from
the rail (such part being shaped and made of the desired strength) to give it
elasticity so that when 'the solid collar is forced into the hole in the rail the slit or
slits and form of the part permit it to give way and the elasticity of the metal
acts to grip the exterior of the collar and hold it with sufficient firmness.
1
The end of the collar is or may be slightly tapered or the entrance to the hole
slightly coned, and each collar is or may be gradually forced into the hole for it
by a screw tool which may pass through the collar and screw into a nut or part
taking hold below 'the part in the 'rail for carrying the collar.

Fig. 1 is an 'end view of a rail showing a projecting arm on each side, each arm
being the holder for a collar such as are used in slubbing and roving frames.
Fig. 2 is cross section on the line A-B fig. 1 and fig. 3 is a cross section on the
line C-D fig. 1.
On the left of fig. 1, the holder (a¹) from the rail a is shown in section, and the
tube or collar b is made of the form shown or of any other suitable form, and with
one or more slits b¹ formed in it, as shown.

1.
"'
The collar or tube b is first bored out and turned with that part which is to
enter the holder al left too large for the hole in it, then the tube or collar b has
the slit or slits b₁ cut in it, and then a collar or other tool having one or more
set screws is placed on the exterior of the tube or collar bas near to the part
which is to enter and be held by the holder a' as convenient and that part of the
tube is thus compressed by the screw or screws in the loose collar or tool and the

page_text: tube is then turned to a size to accurately fit and enter the hole in the holder a¹
so that when the loose collar or tool is removed the elastic action of the metal.
will bring the sides of the tube or collar 6 firmly in contact with the sides of the
hole in the holder a¹.
The edges of the slit or slits b¹ in the tubes b are rounded off as shown in fig. 2
at 6' so as to prevent as far as possible the lubricant which has to be applied to
the bobbin wheel c, shown in section on the left of fig. 1, being scraped by the
edges of the slit from the bore of the bobbin wheel as it rotates.
".
When the tubes or collars b are made with a slit or slits 6' as shown on the
right of fig. 1 they are constructed as herein before described, and turned when
under compression to fit and enter the holes in the holder a¹ as hereinbefore
explained. The lower end 6x of the unslit part of the tube or collar is reduced
small enough to enter the hole in the holder without compression, that part of the
tube or collar which is to be held by the holder being the part turned under
compression to the exact size of the hole in the holder at
The tubes bare or may be inserted in the holes in the holders a¹ by making the
entering end of the tube or collar b slightly conical or the edge of the hole in the
holder a at which the tube or collar enters slightly coned, and then gradually
forcing the tube or collar into its holder (a¹) by a screw passing through the bore
of the tube or collar the screw having a shoulder or collar resting against the
upper end of the tube the lower end of the screw screwing through a nut in a cap
which will pass freely on and over the exterior of the tube or collar and rest.
against the under side of the holder a-A similar tool is or may be used for
withdrawing the tubes or collars from their holders the said cap forming the
abutment against the holder being in this case long enough to pass over the
upper part of the tube or collar b and give space for it to be withdrawn from
the hole in the holder.
In the arrangement of tube or collar on the right of fig. 1-I have shown
and prefer to use a hoop d on the exterior of the tube b to cover the slit or slits b¹
and to form the bearing of the bobbin wheel c.
This hoop & will prevent the lubricant from entering the slit or slits b¹ in the
tube b.
Fig. 4 is an end elevation and fig. 5 a plan of part of a rail a having holders a¹
constructed and arranged to hold ordinary non-elastic collars or tubes b―The
holder a¹ is or may be made in the form shown best in the plan view fig. 5.
The holders a¹ are or may be cast solid but with a hole which may be bored
out and then a slit a² is cut in one side as shown, and a tool or clamp e is or may
be placed on the holder having two set screws one to act upon a wedge so as to
force it into the slit and expand the holder at and the other set screw to prevent
further expansion after the wedge has been forced into the slit, in the act of
rinering out the hole in the holder to the exact size, this being done while the
holder a¹ is expanded or opened by the wedge as above explained.
When the wedge is removed the holder will contract sufficiently by its elasticity
to hold the tube or collar when inserted therein.
The clamp is shown in the plan view fig. 5 and by a front sectional view fig. 6,
and in dotted line by fig. 4.
The clamp is a plate e with a hole in it and a hook e¹ which can hook upon the
rail (see fig. 4.)
The wedge piece ax for opening the slit (a²) is formed similar to a gib for a
cottar and extends on each side of the clamp as shown and is arranged so as to be
forced by the screw e² into the slit a² and when sufficient tension has been brought
upon it by the wedge a* the screw e³ is tightened.
The point of the screw e² is smaller than the other part of the screw and
has a fine pitched thread screwing into a boss from the wedge a* the other part
of the screw being of coarse pitch and thus the rotation of the screw will force
the wedge into the slit when turned one way and draw it out when turned the
other way.

page_text: Fig. 7 illustrates another form of holder al for inelastic collar or tubes. The
hole for the tube (b) is bored out and another hole as is bored then the slit or
slits a² are cut by a reciprocating saw or other cutter.
The hole in the holder is expanded by a tool f having a wedged shaped web
inclined both lengthways, and in cross section which is forced into the hole a³
the web f¹ passing into the slit a³.
A screw clamp is or may be used to prevent the holder from expanding further
while being rimered out to the correct size.
When the tube is inserted in the hole in the holder the wedge piece ƒ may be
withdrawn allowing the elasticity of the metal to close upon and grip the tube.
A lever tool similar to that shown by g figs. 4 and 5 is or may be used to spring
open the holders for inserting or withdrawing the tubes.
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 I
do not claim the making of tubes or collars for the spindles of slubbing and roving
frames elastic so as to be self securing when inserted in the holes in the holders-
but what I do claim is,
1. The construction of elastic collars or tubes for the spindles of slubbing and
roving frames in the manner and for the purpose hereinbefore described.
2. The combination of a hoop d with the tube or collar 6 for the bobbin wheel c
to rotate upon as hereinbefore described.
3. The construction of the holders with elasticity to receive and hold non-elastic
tubes or collars in the manner and for the purpose hereinbefore described and
illustrated by figs. 4, 5, 6 and 7 of the drawings.
