SPINDLES OF SPINNING MACHINERY, AND IN THE METHODS OF AND ARRANGE-
PROVISIONAL SPECIFICATION left by the said Amos Ogden, Thomas Marsh,
John Clayton, and Abraham Mills at the Office of the Commissioners of Patents
on the 29th June 1878.
AMOS OGDEN THOMAS MARSH and JOHN CLAYTON all of Ashton-under-Lync in
the County of Lancaster and ABRAHAM MILLS of Dukinfield in the County of
Chester. "IMPROVEMENTS IN THE SPINDLES OF SPINNING MACHINERY AND IN THE
METHODS OF AND ARRANGEMENTS FOR MOUNTING ADJUSTING AND LUBRICATING
THE SAME."
Our Invention relates in the first place principally to the " ring and traveller "
throstles employed in spinning but may also be applicable wholly or in part to
other descriptions of throstles or of spinning machinery.
In the first place we mount the spindle in and upon top and bottom bearings
formed or secured in parts which are connected together and secured to a single
rail. The spindle is bored upwards from the bottom to about the part which
revolves in the upper bearing and in the lower part of the spindle or in a bush
fixed therein is formed a bearing which is formed to suit a stump which sustains
the said spindle. The said stump is by preference formed with a coned top and is
fixed or formed in an oil lubricant reservoir which is formed to screw upon or to be
otherwise secured to a bolster in which the upper bearing is formed or fixed.
In some cases we may bore and turn the two parts to fit and secure the reservoir
in position by means of a set screw or of set screws or we may otherwise secure
the two parts together.
A side aperture at or near the inner end of the internal cavity in the spindle
permits lubricant to flow out of the said cavity to supply the upper bearing. The
said reservoir is supplied with lubricant which when the spindle revolves we have
found to flow upwards through the central cavity of the spindle whereby a constant
supply of lubricant to both bearings is ensured so long as there is a sufficient supply
in the reservoir.
We prefer to form the length of the spindle below the upper bearing larger in
diameter than the part revolving in such bearing.

page_text: A second part of our Invention relates to the arrangements for securing the
bolsters to the rail and is applicable to the arrangement just described and also to
other arrangements. We screw the portion of the bolster which passes through the
rail and we secure the bolster in position by means of a nut which is formed with
a boss which enters the hole in the rail. The square hexagonal or other shaped
head of the nut is turned recessed or chambered out so as to serve as an oil cup
whence oil may be supplied to the spindle through an orifice in the bolster. When
the nut is tightened a collar on the bolster bears against the under side of the rail
the margin of the hole in the rail being by preference faced with a revolving cutter.
The said hole in the rail is a little larger than the boss of the nut so that the
spindle can be adjusted in position.
As an additional security we may employ set screws bearing against the under
side of the rail and screwing into the under collar on the bolster or into lugs
thereon or on the part to which the oil reservoir referred to in the first part of our
Invention is secured.
In another arrangement a part of the bolster or the foot of the spindle when a
dead spindle is employed is turned excentric and fits in an excentrically situated
hole in a split bush which is or may be fixed in the rail by means of a set screw.
According to a third part of our Invention we form the part of the bolster which
is below the rail with a chamber within which the "whorl " is mounted the part
in which the footstep is formed screwing into and occupying the hole through which
the whorl is passed into position the screwed footstep also serving to effect the
adjustment of the parts.
A fourth part of our Invention is suitable more particularly for application in the
formation of mule spindle footsteps. We form a number of bearings in or on a plate
which is formed with a raised back on the top of which is cast formed or fixed a
covering plate which is drilled for the passage of the lower ends of the spindles. The
bearings are or may be countersunk. An open space which may or may not be
provided with a hinged door or flap is left between the said covering plate and
raised edge and through this space the lubricant is supplied at the required intervals
and access is had to remove the dirty lubricant when desirable.
In some or in all cases we form parts for the bearings of a suitable metal and
then place them in moulds in which the other parts are cast in a cheaper metal.
A fifth part of our Invention is designed for application to the bolster plates or
upper bearings of mule spindles.
In one arrangement two bearings are formed in one casting and between the two
bearings is formed a recess which communicates by means of end openings with the
two bearings. A piece of felt or other absorbent material to hold the lubricant and
to supply it to the spindle is or may be inserted into the said recess.
In another arrangement a greater number of bearings are formed in paps which
extend above the bottom of the said recess and the bearings communicate by means
of side openings with the said recess. A piece of felt or absorbent material is
punched with holes to suit the said paps and lies in the said recess. The lubricant
is supplied to the bearings by means or partly by means of the said felt or
material.
A remaining part of our Invention is applicable to largen spindles such for
example as throstle spindles. The footstep bearing is drilled in a pap cast upon
the bottom of a trough. Upon the upper part of the trough is cast a boss through
which the spindle passes. Access to the trough for the supply of lubricant and for
cleaning the trough is had through an opening at each side of the said boss and
these openings are covered by a plate which can be slid upwards on the boss when
lubricant is to be supplied to the trough.

Our Invention relates principally to the ring and traveller throstles employed in
spinning but may also be applicable wholly or in part to other descriptions of
throstles or of spinning machinery.
In the first place we mount the spindles in bearings formed in bolsters or parts
which are secured to the rail and we provide each spindle with an oil or lubricant
reservoir which supplies lubricant to the footstep of the spindle. The said reservoir
is supplied with lubricant which when the spindle revolves flows upwards to
supply the upper bearing and returns by descending to the reservoir.
We thus
obtain a constant lubrication so long as there is a sufficient supply of lubricant in
the reservoir.

mounted an oil cup in which the footstep is formed occupying the hole through
which the whorl is passed into position the said oil cup also serving to effect the

page_text: And in order that our Invention may be fully understood we have appended
hereunto a Sheet of Drawings marked with letters of reference to which Drawings
we will now refer.
Fig. 1 represents a vertical section illustrative of the first part of our Invention.
In the said Fig. a is a spindle which is fitted to revolve in a bolster b which is
secured to the rail c. The lower end of the said bolster is formed with a collar d
and upon a portion of the bolster is formed a screw thread. A nut e engages with
the said thread, and serves as means for securing the bolster in position upon the
rail.
A boss upon the said nut projects into the hole in the rail and the said hole is
larger than the diameter of the said boss so that the position of the bolster can be
adjusted. This method-of--adjustment-forms-a-portion-of-the-second--part-of-our
Invention. In the example the bolster is bushed with a lining of gun metal or
other suitable alloy but this lining may be dispensed with. The lower part of the
collar d is in the form of a hollow cylinder and upon the exterior of this part a
screw thread is formed. An oil cup or lubricant reservoir g is fitted to screw upon
the said collar. In the centre of the said cup a steel iron or metal stud h is fixed
and this stud enters an enlarged part of the bore in the spindle a. The upper part
of the said stud is coned and the spindle is prepared to revolve upon this coned
part which acts as a footstep for the spindle. A sleeve i is screwed upon the
spindle and the lower part of this sleeve is formed as a wharve by means of which
the spindle is driven. The nut e is cupped and passages j are formed in the said
nut and in the collar d so that oil poured into the cup in the said nut flows into
the cup g.
In lieu of this arrangement the cup g may be removed when it is necessary to
supply it with oil.
When the spindle is revolving rapidly the oil enters at the footstep that is to say
at the lower end of the spindle and flows upwards to an outlet opening formed at k
through which the oil flows into the bearing in the bolster and descends through
the said bearing into the cup g. A circulation of oil through the bearing is
thus maintained so that both the footstep and the upper bearing are thoroughly
lubricated.
Fig. 2 is a corresponding section illustrative of a modification in the arrangement.
In this example the oil cup g is formed in one piece with the bolster or is cast
upon or fixed to the raid bolster and the bottom of the bearing formed in the
bolster constitutes the footstep. The lubricant flows to the footstep through holes /
in the lower part of the bolster. The action is similar to that of the previous
example. When the spindle is at work the oil flows through the holes to the
footstep and ascending through the bearing to the upper end of the bolster descends
through the space between the bolster and the inside of the sleeve i to the oil
cup. Fig-2-also-illustrates the second-part-of-var Invention: The cup 9 is formed
with a screwed shank upon which is screwed a plate m which is drilled and
tapped to receive screws n. The hole in the rail is a little larger than the said
shank, so that the position of the spindle can be adjusted. When adjusted the
bolster is secured in position by tightening up the screws n so that their ends bear
forcibly against the rail. This arrangement may be employed in connection with
the nut fastening referred to when describing Fig. 1.
Fig. 3 illustrates the third another part of our Invention. In this example the
bolster is secured to the rail by means of a nut e which also serves as an oil cup
and permits the bolster to be adjusted in. position in accordance with the second
preceding part of our Invention. In the part of the bolster which is below the
rail we form a chamber within which the whorl or warve o is mounted the said
chamber being open at the two sides to permit of the passage of the endless band.
In the example the said chamber is formed by connecting a boss p with a shoulder.d
upon the bolster by means of two arms 77 the whole being cast together. A hole
sufficiently large to permit of the passage of the whorl is bored in the boss pand

page_text: in the said hole an oil cup g is fitted. In the said oil cup a footstep to receive the
lower end of the spindle is formed. The said cup is secured by means of a set
screws or it may be arranged to screw into the hole in the said boss. An oil
passage is formed in one of the arms and when oil is poured into this passage
it flows partly into the cup g and partly to the lower end of the bearing in the
bolster. By moving the oil cup g up or down the positions of certain of the parts
are adjusted. The oil cup e is supplied with oil to lubricate the upper part of the
bearing in the bolster. A spring brake A is employed to arrest the motion of
the spindle when required.
The remaining Figs. are illustrative of-the-fourth-part-of-our-Invention.

the County of Lancaster, and ABRAHAM MILLS, of Dukinfield, in the County of
Chester. IMPROVEMENTS IN THE SPINDLES OF SPINNING MACHINERY; AND IN THE
METHODS OF AND ARRANGEMENTS FOR MOUNTING, ADJUSTING, AND LUBRICATING
THE SAME."
Our Invention relates, in the first place, principally to the "ring and traveller"
throstles employed in spinning, but may also be applicable wholly or in part to
other descriptions of throstles or of spinning machinery.
In the first place, we mount the spindle in and upon top and bottom bearings
formed or secured in parts, which are connected together and secured to a single
rail. The spindle is bored upwards from the bottom to about the part which
revolves in the upper bearing, and in the lower part of the spindle, or in a bush
fixed therein, is formed a bearing which is formed to suit a stump which sustains
the said spindle. The said stump is by preference formed with a coned top, and is
fixed or formed in an oil lubricant reservoir, which is formed to screw upon or to be
otherwise secured to a bolster in which the upper bearing is formed or fixed.
In some cases we may bore and turn the two parts to fit and secure the reservoir
"

page_text: in position by means of a set screw or of set screws, or we may otherwise secure
the two parts together.
A side aperture at or near the inner end of the internal cavity in the spindle
permits lubricant to flow out of the said cavity to supply the upper bearing. The
said reservoir is supplied with lubricant which, when the spindle revolves, we have
found to flow upwards through the central cavity of the spindle, whereby a constant
supply of lubricant to both bearings is ensured so long as there is a sufficient supply
in the reservoir.
We prefer to form the length of spindle below the upper bearing larger in diameter
than the part revolving in such bearing.
A second part of our Invention relates to the arrangements for securing the
bolsters to the rail, and is applicable to the arrangement just described, and also to
other arrangements. We screw the portion of the bolster which passes through the
rail, and we secure the bolster in position by means of a nut which is formed with
a boss which enters the hole in the rail. The square; hexagonal, or other shaped
head of the nut. is turned, recessed, or chambered out so as to serve as an oil cup,
whence oil may be supplied to the spindle through an orifice in the bolster. When
the nut is tightened a collar on the bolster bears against the under side of the rail,
the margin of the hole in the rail being by preference faced with a revolving cutter.
The said hole in the rail is a little larger than the boss of the nut, so that the
spindle can be adjusted in position.
As an additional security we may employ set screws bearing against the under
side of the rail, and screwing into the under collar on the bolster, or into lugs
thereon, or on the part to which the oil reservoir referred to in the first part of our
Invention is secured.
In another arrangement a part of the bolster, or the foot of the spindle when a
dead spindle is employed, is turned excentric, and fits in an excentrically situated
hole in a split bush, which is or may be fixed in the rail by means of a set screw.
According to a third part of our Invention, wo form the part of the bolster which
is below the rail with a chamber, within which the "whorl " is mounted, the part
in which the footstep is formed scrowing into and occupying the hole through which
the whorl is passed into position, the screwed footstep also serving to effect the
adjustment of the parts.
A fourth part of our Invention is suitable more particularly for application in the
formation of mule spindle footsteps. We form a number of bearings in or on a plate
which is formed with a raised back, on the top of which is cast, formed, or fixed a
covering plate which is drilled for the passage of the lower ends of the spindles. The
bearings are or may be countersunk. An open space, which may or may not be
provided with a hinged door or flap, is left between the said covering plate and
raised edge, and through this space the lubricant is supplied at the required intervals,
and access is bad to remove the dirty lubricant when desirable.
In some or in all cases we form parts for the bearings of a suitable metal, and
then place them in moulds, in which the other parts are cast in a cheaper. metal.
A fifth part of our Invention is designed for application to the bolster plates or
upper bearings of mulo spindles.
In one arrangement two bearings are formed in one casting, and between the two
bearings is formed a recess which communicates by means of end openings with the
two bearings. -A piece of felt or other absorbent material to hold the lubricant and
to supply it to the spindle is or may be inserted into the said recess.
In another arrangement a greater number of bearings are formed in paps, which
extend above the bottom of the said recess, and the bearings communicate by means
of side openings with the said recess. A piece of felt or absorbent material is
punched with holes to suit the said paps, and lies in the said recess. The lubricant
is supplied to the bearings by means or partly by means of the said felt or
material.
A remaining part of our Invention is applicable to larger-spindles, such, for
example, as throstle spindles. The footstep bearing is drilled in a pap cast upon

page_text: the bottom of a trough. Upon the upper part of the trough is cast a boss, through
which the spindle passes. Access to the trough for the suppply of lubricant and for
cleaning the trough is had through an opening at each side of the said boss, and
these openings are covered by a plate which can be slid upwards on the boss when
lubricant is to be supplied to the trough.

"
Our Invention relates principally to the ring and traveller throstles employed in
spinning, but may also be applicable wholly or in part to other descriptions of
throstles or of spinning machinery.
In the first place, we mount the spindles in bearings formed in bolsters or parts
which are secured to the rail, and we provide each spindle with an oil or lubricant
reservoir, which supplies lubricant to the footstep of the spindle. The said reservoir
is supplied with lubricant which, when the spindlo revolves, flows upwards to
supply the upper bearing, and returns by descending to the reservoir. We thus
obtain a constant lubrication so long as there is a sufficient supply of lubricant in the
reservoir.
A second part of our Invention relates to the arrangements for securing the
bolsters to the rail, and is applicable to the arrangement just described, and also to
other arrangements.
According to a third part of our Invention. we form the part of the bolster which
is below the rail with a chamber, within which the "whorl" is mounted, an oil cup
in which the footstep is formed occupying the hole through which the whorl is
passed into position, the said oil cup also serving to effect the adjustment of the
parts.
A fourth part of our Invention is suitable more particularly for application to or
in the formation of mule spindle footsteps. We form a number of bearings in or on
a plate which is formed with a raised back, on the top of which is cast, formed, or
fixed a covering plate which is drilled for the passage of the lower ends of the
spindles. The bearings are or may be countersunk. An open space, which may
or may not be provided with a hinged door or flap, is left between the said
covering plate and raised edge, and through this space the lubricant is supplied

page_text: at the required intervals, and access is had to remove the dirty lubricant when
desirable.
A modification is applicable to existing footsteps.
And in order that our Invention may be fully understood we have appended
hereunto a Sheet of Drawings marked with letters of reference, to which Drawings
we will now refer.
Fig. 1 represents a vertical section illustrative of the first part of our Invention.
In the said Fig. a is a spindle which is fitted to revolve in a bolster b, which is
secured to the rail c. The lower end of the said bolster is formed with a collar d,
and upon a portion of the bolster is formed a screw thread. A nut e engages with
the said thread, and serves as means for securing the bolster in position upon the
rail. A boss upon the said nut projects into the hole in the rail, and the said hole is
larger than the diameter of the said boss, so that the position of the bolster an be
adjusted; this method of adjustment forms a portion of the second part of our
Invention. In the example the bolster is bushed with a lining f of gun metal or
other suitable alloy, but this lining may be dispensed with. The lower part of the
collar dis in the form of a hollow cylinder, and upon the exterior of this part a
screw thread is formed. An oil cup or lubricant reservoir g is fitted to screw upon
the said collar. In the centre of the said cup a steel, iron, or metal stud h is fixed,
and this stud enters an enlarged part of the bore in the spindle a. The upper part
of the said stud is coned, and the spindle is prepared to revolve upon this coned
part, which acts as a footstep for the spindle. A sleeve i is screwed upon tho
spindle, and the lower part of this sleeve is formed as a wharve, by means of which
the spindle is driven. The nut e is cupped, and passages ; are formed in the said
nut and in the collar d, so that oil poured into the cup in the said nut flows into a
the cup g.
In lieu of this arrangement the cup g may be removed when it is necessary to
supply it with oil.
When the spindle is revolving rapidly the oil enters at the footstep, that is to say,
at the lower end of the spindlo, and flows upwards to an outlet opening formed at,
through which the oil flows into the bearing in the bolster, and descends through
the said bearing into the cup g. A circulation of oil through the bearing is
thus maintained, so that both the footstep and the upper bearing are thoroughly
lubricated.
Fig. 2 is a corresponding section illustrative of a modification in the arrangement.
In this example the oil cup g is formed in one piece with the bolster, or is cast
upon or fixed to the said bolster, and the bottom of the bearing formed in the
bolster constitutes the footstep. The lubricant flows to the footstep through holes
in the lower part of the bolster. The action is similar to that of the previous
example. When the spindle is at work the oil flows through the holes to the
footstep, and ascending through the bearing to the upper end of the bolster descends
through the space between the bolster and the inside of the sleeve i to the
oil cup.
Fig. 2 also illustrates the second part of our Invention. The cup g is formed
with a screwed shank, upon which is screwed a plate m, which is drilled and
tapped to receive screws n. The hole in the rail is a little larger than the said
shank, so that the position of the spindle can be adjusted. When adjusted tho
bolster is secured in position by tightening up the screws n, so that their ends bear
forcibly against the rail. This arrangement inay be employed in connection with
the nut fastening referred to when describing Fig. 1.
Fig. 3 illustrates the third part of our Invention. In this example the bolster is
secured to the rails by means of a nut e, which also serves as an oil cup and permits
the bolster to be adjusted in position, in accordance with the second part of our
Invention. In the part of the bolster which is below the rail we form a chamber,
within which the whorl or warve o is mounted, the said chamber being open at the
two sides to permit of the passage of the endless band. In the example the said

page_text: chamber is formed by connecting a boss p with a shoulder d upon the bolster by
means of two arms 7, 7, the whole being cast together. A hole sufficiently large to
permit of the passage of the whorl is bored in the boss p, and in the said hole an oil
cup g is fitted. In the said oil cup a footstep to receive the lower end of the spindle
is formed. The said cup is secured by means of a set screw 8, or it may be arranged
to screw into the hole in the said boss. An oil passage t is formed in one of the
arms r, and when oil is poured into this passage it flows partly into the cup g.and
partly to the lower end of the bearing in the bolster. By moving the oil cup gup
or down, the positions of certain of the parts are adjusted. The oil cup e is supplied
with oil to lubricate the upper part of the bearing in the bolster. A spring brake A
is employed to arrest the motion of the spindle when required.
The remaining Figs. are illustrative of the fourth part of our Invention.
In Figs. 4, 5, and 6 u, u, represent the lower ends of mule spindles, and B repre-
sents a portion of the rail or board in which the footsteps are secured.
In Figs. 4 and 5 is the aforesaid plate, to which are united four footstep
bearings w. Upon the said plate are cast a back x, two ends y, and a top z, so as
to form an open-fronted box. Holes to clear the spindles are drilled or formed in
the top. The box so forined is fitted with a door which is hinged so that it can
be opened and closed.
In Fig. 4 the said door is represented as closed, and in Fig. 6 as when open.
In practice we form two trunnions on each end of the door, and cause these to
enter holes in the two ends of the box.
In Figs. 4 and 5 the footstep bearings are supposed to be made of gun metal, or
of the ordinary metal used for the purpose. Wo place these bearings in a mould of
a suitable form, and run in a cheaper metal, composed principally of zinc and lead.
We are thus enabled to reduce the cost of this form of lubricator, but, if preferred,
the bearings and the box may be cast together in any suitable metal.
To check the splashing of the oil we prefer to place a piece of perforated felt,
flannel, or similar material a' on the bottom of the box.
To lubricate the four footsteps it is only necessary to pour a little oil into the box,
which retains it for a comparatively long time, and supplies it to the footsteps as
required.
Less or more than four footsteps may be supplied by one box.
Fig. 6 illustrates a modification suitable for application to old mules without
removing the existing footsteps. In this example the box is formed without the
bearings, and holes are formed in the bottom of the box, that is to say, in the plate v,
through which holes the spindles pass to the footsteps. In this case it is advisable
to screw the plate v to the board B, and to interpose a suitable packing cement or
material, which will prevent the escape of the oil.
In our Provisional Specification we mentioned other arrangements under the
heads of the fifth and sixth parts of our Invention, but we have intentionally not
included such parts herein, and therefore make no claim in respect thereof.
Having now fully set forth and indicated the nature of our said Invention, and
means for carrying the same into practical effect, we would have it to be understood
in conclusion that we claim,-
First. The combinations of parts, arranged and acting substantially as and for the
purposes set forth, and indicated herein-before and by Figs. 1, 2, and 3 of the accom-
panying Drawings.
Secondly. The oil cups g, supplying lubricant directly to the footsteps of
spindles revolving in bolsters, substantially as and for the purpose set forth and
indicated.
Thirdly. The nut e, serving to secure the bolster in position, and as a means for
adjustment, and also as a cup to receive lubricant.
Fourthly. The method of adjusting the bolster and securing it by means of two
set screws, substantially as set forth and indicated.
Fifthly. The box or arrangement for containing lubricant and supplying the same
to the footsteps of mules, substantially as set forth and indicated.

page_text: And, lastly. The lubricator box cast in a cheap "white metal" upon the mule
footstep castings, substantially as set forth and indicated.
In witness whereof, I, the said Amos Ogden, for myself and on behalf of the
said Thomas Marsh, John Clayton, and Abraham Mills, have hereunto set
my hand and seal, this Twenty-seventh day of December, in the year of our
Lord One thousand eight hundred and seventy-eight.
