Year: 1883

page_text: LETTERS PATENT to William Tatham of Vulcan Works, Rochdale, in the
County of Lancaster, Machine maker for an Invention of "IMPROVEMENTS
IN OR APPLICABLE TO MACHINES FOR SLUBBING, ROVING, SPINNING AND
WINDING FIBROUS MATERIALS"
PROVISIONAL SPECIFICATION left by the said William Tatham at the
Office of the Commissioners of Patents on the 17th October 1883.
WILLIAM TATHAM, of Vulcan Works, Rochdale, in the County of Lancaster,
Machine Maker. "IMPROVEMENTS IN OR APPLICABLE TO MACHINES FOR SLUBBING,
ROVING SPINNING AND WINDING FIBROUS MATERIALS,"
My invention has reference to the parts for carrying and holding the collars,
tubes and steps of the spindles of the machines above referred to, and of holding
the "dead" spindles of a certain class of spinning machines.
Collars tubes and steps which form the bearings of spindles especially those used
in slubbing and roving frames, have been hitherto placed in a hole bored in the
rails, or in parts from the rails which have to carry them, and have then been
secured by a set screw, or by screw nuts screwing on to collar, tube or step.
In some cases the hole in the rail has been screw tapped and the collar, tube or
step has been screwed to screw into the hole in the rail.
These methods are objectionable and have been a source of great trouble, as the
set screw acting on one side is almost certain to push the collar, tube or step out of
its true central position in the hole for it, and distort the collar or tube, and when
screw nuts are used upon the screwed collar or tube they are very liable to be
strained and thrown out of the true central position which they ought to occupy.
My invention consists in combining with slubbing, roving, spinning and winding
machines, improved arrangements and constructions of the parts which are to carry
and retain the collar, tube and step bearings of the spindles of such machines, so
that such bearings may be truly held and secured therein without straining or

page_text: throwing the bearings out of their true positions, and which arrangements and
constructions allow of the bearings, being removed and replaced with a certainty
that they will when replaced be in their true position, which in most instances, is
not so with the ordinary modes of fixing, and the collar, tube or step will
accordingly, in such cases, have to be readjusted.
The improved arrangements and constructions, above referred to consist in
forming the parts, which are to carry the collars, tubes or steps by projections cast
or formed on the rails or by forming them of brackets secured to the rails, these
parts having bosses which are bored out truly to fit the exterior of the collar, tube
or step and then one side is cut open and the sides which are cut open have flanges
for one or more set screws which pass through one flange and screw into the other
so that the two flanges can be thus drawn together to grip firmly the exterior of
the collar, tube or step, when placed therein.
The boss is shaped to permit of a certain amount of elasticity in the two jaws of
the boss which have to grip the collar tube or step, and in some cases to increase
, this elasticity, a cut is made in the boss opposite to that between the flanges.
According to another modification of my invention the holding part to carry the
bearing is arranged with a cap secured by two or more screws or bolts-the boss
and cap are or may be cast together leaving two solid parts to be cut, to separate
the cap from the boss after the hole to fit the exterior of the collar, tube or step
has been truly bored, thus leaving one half the hole in each part; the bearing is
held by screwing the cap against it when inserted in the hole.
According to another modification the rails for the collar, tube or step bearings,
are formed or cast, solid, and the holes are bored, and they are then cut in two,
and set screws or bolts are used to secure the parts together to firmly grasp the
collars, tubes or steps; or the rails may be formed in two parts screwed together
and then bored out.
The arrangements described are also applicable for holding "dead" spindles.

by the said William Tatham in the Patent Office on the 16th April 1884.
WILLIAM TATHAM of Vulcan Works, Rochdale, in the County of Lancaster,
Machine Maker, "IMPROVEMENTS IN OR APPLICABLE TO MACHINES FOR SLUBBING,
ROVING, SPINNING AND WINDING FIBROUS MATERIALS,"
My invention has reference to the parts for carrying and holding the collars,
tubes and steps, of the spindles of the machines above referred to.
Collars, tubes and steps which form the bearings of spindles especially those
used in slubbing and roving frames have been hitherto placed in a hole bored in
the-rails, or in parts from the rails which have to carry them, and have then been
secured by a set screw, or by screw nuts screwing on to the collar tube or step.
In some cases the hole in the rail has been screw tapped and the collar, tube or
step has been screwed to screw into the hole in the rail.
These methods are objectionable and have been a source of great trouble, as the
set screw acting on one side is almost certain to push the collar tube or step out of
its true central position in the hole for it, and distort the collar or tube, and when
screw nuts are used upon the screwed collar or tube they are very liable to be
strained and thrown out of the true central position which they ought to occupy.
My invention consists in combining with slubbing, roving, spinning and winding
machines, improved arrangements and constructions of the parts which are to carry
and retain the collar tube and step bearings of the spindles of such machines, so
that such bearings may be truly held and secured therein without straining or
throwing the bearings out of their true positions and which arrangements and
constructions allow of the bearings being removed and replaced with a certainty
that they will when replaced be in their true position, which in most instances is
not so with the ordinary modes of fixing and the collar tube or step will accordingly`
in such cases have to be readjusted.
The improved arrangements and constructions above referred to consist in
forming the parts which are to carry the collars tubes or steps by projections cast
or formed on the rails, or by forming them of brackets secured to the rails, these
parts having bosses which are bored out truly to fit the exterior of the collar tube
or step and then one side is cut open and the sides which are cut' open have flanges
or lugs for bolts or for one or more set screws which pass through one flange or lug
and screw into the other so that the two flanges or lugs can be thus drawn together
to grip firmly the exterior of the collar tube or step, when placed therein.
The boss is shaped to permit of a certain amount of elasticity in the jaw or jaws
of the boss which have to grip the collar, tube or step, and in some cases to increase
this elasticity, a cut is made when desired in the boss, opposite to that between the
flanges or lugs.
According to another modification of my invention the holding part to carry the
bearing is arranged with a cap secured by one two or more screws or bolts-the
boss and cap are or may be cast together leaving two solid parts to be cut, to
separate the cap from the boss after the hole to fit the exterior of the collar tube or
step has been truly bored thus leaving about one half the hole in each part; the
bearing is held by screwing the cap against it when inserted in the hole.
According to another modification the rails for the collar tube or step bearings
are formed or cast solid and the holes are bored, and they, are then cut' in two and
set screws or bolts are used to secure the parts together to firmly grasp the collars,
tubes or steps; or the rails may be formed in two parts screwed together and then
bored out

invention combined with spindle bearings for slubbing or Roving frames.—Fig 3 is
a plan of the collar or tube rail, and 6g 4 is a view at the front of the rail showing
the collar tube and step and the parts for holding the same in section, for one
spindle.
a represents the footstep rail; and 6 the collar or tube rail; a¹ the foot step;
61 the collar or tube and c the spindle and d the flyer. e the horizontal shafts
having bearings on the rail b, e' the skew bevel wheels on the shafts for driving
the bobbin wheels c¹, rotating on the tubes or collars.
The parts above referred to by letters are ordinary parts.
Projections are cast on the rails a and b as shown one for each spindle bearing,
these parts are by preference cast solid or with the hole complete where the hole is
to be bored for the step collar or tube but the flange or lug part for the set screw f,
or screws is cast with a slit, but the slit is not extended through to the inside of
the hole for the step collar or tube until after the hole is bored out to accurately
fit the step collar or tube which is turned on its exterior to fit the bored out hole.
Fig 5 is a front view, fig 6 a cross section, and fig 7 a plan representing a rail
where the front of the part for holding the collar tube or step, can be entirely
removed.
New rails and bearing holders may be constructed according to this modification,
but it is more particularly intended for use in replacing carriers which have been
broken by accident.
The cap part g in this case is fitted to the arm part which is solid with or secured
to the rail, and is screwed to it and the hole for the step collar or tube is then bored
out.
Then the cap part g is detached and a little of the face or faces coming against
each other is removed to give sufficient space to allow it to close firmly upon the
exterior of the step, collar or tube when screwed up by the set screw (f) or
screws.
The flanges or lugs may be placed in any convenient position and one or more
screws, on each side may be used, if desired.
Fig 8 is a front elevation, fig 9 a cross section and fig 10 a plan view illustrating
another modification of my invention.
In this modification, a part to carry the step collar or tube, is cast on the rail
and a bolt f¹ is formed to pass through the rail as shown the bolt having an eye in
it for the step, collar or tube to pass through.
That part of the carrier cast on or attached to the rail is formed or bored out to
fit the exterior of the step, collar or tube-and when the eye bolt is in its place and
screwed up, the collar, tube or step is secured firmly against the bored out part on
the rail.
Fig 11 is a front elevation partly in section fig 12 a cross sectional elevation and
fig 13 a plan illustrating my invention as applied to and combined with the spindle
bearings of ring spinning frames.
The lower end of each tube 6' forming or carrying the step and collar for each
spindle is turned to fit holes formed in a rail in which it is secured as illustrated
in the figures and hereinbefore described in reference to figs 1, 2 and 3.
Fig 14 is a front, fig 15 a cross sectional elevation and fig 16 a plan, illustrating
my invention combined with and applied to a rail suitable for the steps and collars
of Throstle spinning and doubling frames, and for winding or other frames.
In this modification the part to hold the step collar or tube for the twisting and
winding spindle is formed in a part cast under the upper part of the rail, and the
set screw f screws through a rib h on the rail and its point comes against the
flange or lug g' to hold it firmly against the step collar or tube.
I have now particularly described the nature of my said invention and the modes
of carrying the same into effect and claim as my invention.
1. The combination with slubbing and roving frames of the arrangement
construction and mode of securing the step, collar and tube bearings of the twisting

page_text: and winding spindles of such machines substantially as hereinbefore described and
illustrated by the drawings
2. The combination with ring spinning and doubling frames of the arrangement
construction and mode of securing the bearings or the carrier of the bearings of the
twisting spindles of such machines substantially as herein before described and
illustrated by the drawings.
3. The combination with throstle spinning and doubling frames of the arrange-
ment construction and mode of securing the step, collar and tube bearings
of the twisting and winding spindles of such machines as hereinbefore described
and illustrated by the drawings.
4. The combination with machines having spindles for spinning, twisting or
winding slivers, yarns or threads of the arrangement construction and mode of
securing the step collar and tube bearings of such spindles substantially as herein-
before described.
In Witness whereof I the said William Tatham have hereunto set my hand
and seal this fifteenth day of April in the year of our Lord one thousand eight
bundred and eighty four.
