both of Oldham in the County of Lancaster. "IMPROVEMENTS IN APPARATUS
FOR LUBRICATING THE SPINDLES OF SPINNING AND DOUBLING MACHINES."
Our invention consists in forming a chamber or cavity around the collar or tube
within which the spindle revolves, such chamber forming a reservoir for containing:
lubricating material. Through the tube or collar before named we form an opening
or openings communicating with the interior of the said reservoir and spindle.
The exterior of the before named reservoir we provide with a nut screwing thereon
which in conjunction with a collar formed upon the said reservoir enables us to
secure such reservoir upon the spindle rail, or we form a projecting flange upon.
the reservoir aforesaid through which may pass bolts or set screws by which the
said reservoir may be attached to the spindle rail. In the upper part of the
reservoir we form an opening or openings for introducing the lubricating material,
and the bottom of such reservoir we also provide with a plug or tap by means of
which the lubricant may be removed from the said reservoir.
Our invention further consists in forming the nut ordinarily used for securing
the collar supporting the spindle, to the spindle rail, so as to constitute a reservoir
or cavity for containing the lubricating material. For this purpose we form the
cavity or reservoir as an extended portion of the nut aforesaid, the interior of such .
cavity or reservoir communicating with the spindle above named by means of an
aperture, or apertures.
The upper part of the said reservoir we'provide with an aperture, or apertures,
for introducing the lubricating material and we also provide such reservoir or
cavity with a plug or tap for the purpose of removing the lubricant when desired.

FOR
Our Invention consists in forming a chamber or cavity around the collar or tube
within which the spindle revolves, such chamber forming a reservoir for containing
lubricating material. Through the tube or collar before nained we form an
opening or openings communicating with the interior of the said reservoir and
spindle. The exterior of the before named reservoir we provide with a nut
screwing thereon which in conjunction with a collar formed upon the said reservoir
enables us to secure such reservoir upon the spindle rail, or we form a projecting
flange upon the reservoir aforesaid through which may pass bolts or set screws by
which the said reservoir may be attached to the spindle rail. In the upper part
of the reservoir we form an opening or openings for introducing the lubricating
material and the bottom of such reservoir we also provide with a plug or tap by
means of which the lubricant may be removed from the said reservoir. The upper
part of the said reservoir we provide with an aperture or apertures for introducing
the lubricating material and we also provide such reservoir or cavity with a plug
or tap for the purpose of removing the lubricant when desired-In order that our
invention may be more thoroughly understood and more readily carried into
effect we will now proceed to describe the same reference being made to the
accompanying Drawings. Fig: 1 is an elevation partly in section illustrating the
first part of our invention. At 1 is a tube or collar within which is a spindle 2
supported by a footstep 3 and bush 4 placed within the tube or collar 1 within
which the spindle 2 is capable of being freely revolved. A portion 1* of the tube 1
we form of an increased diameter which is made taper so as to fit within an outer
tube 5 the interior of which is made conical by boring turning or in any other
suitable manner so as to receive the taper portion 1* of the tube 1.-At the lower
end of the outer tube 5 is a screw plug 6 screwed into an aperture formed in the
said tube so as to close the same. Upon the outer tube 5 we form a flange 5*
which flange rests upon the spindle rail 7 through which the lower portion of the
outer tube 5 passes and is secured upon the spindle rail 7 by means of a nut 8
capable of being screwed upon screw threads formed upon the outer surface
of the tube 5-The space 9 enclosed between the outer tube 5 and the collar or
tube 1 constitutes a reservoir for containing lubricating material and through the
side of the collar 1 we form an opening 10 by which the said lubricating material
has access to the spindle 2-Within the boss 1* we form a groove 11 as shewn in
Fig: 2 which is a section taken upon the line A. B of Fig: 1. The groove 11
communicates at its upper end with an aperture 12 formed through the flange 5*
through which aperture lubricating material may be introduced through the
groove 11 into the reservoir 9 from which it may pass to the spindle 2 through the
remove the
opening 10-When from any cause it is thought desirable to
lubricating material from the reservoir 9 the plug 6 may be unscrewed and
the lubricant removed from the chamber 9 after which the plug 6 may be again
inserted into the tube 5 and an additional or fresh supply of lubricating material
introduced into the chamber 9 through the aperture 12-Instead of removing the
plug 6 a syringe may be inserted through the aperture 12 into the chamber 9 and
the lubricating material extracted by the syringe in which case the plug 6 may be
allowed to reinain or to be dispensed with and the reservoir formed with a solid

page_text: end as shewn in Fig: 3. Similar letters of reference being placed upon parts
corresponding to those of Figs 1 and 2. By means of the above named syringe,
the condition of the lubricant within the reservoir or chamber 9 may at any time
be ascertained without disturbing the spindle. A modification of the previously
described arrangement is shewn in Fig. 5 which is a vertical side view partly in
section. At 13 is a tube or collar upon which is formed a flange 13* resting upon
a spindle rail 14 through which spindle rail the lower part of the said collar passes.
Upon the outside of the collar 13 are formed screw threads and capable of being
screwed thereon is a nut 15 by means of which and the flange 13× the collar 13 is
secured to the spindle rail 14. The collar 13 is extended in an upward and
downward direction and is formed as a tube the upper part of which carries a
bush 16 and the lower part a footstep 17 which support a spindle 18 capable of
being rotated therein. The lower part of the larger diameter of the collar is
formed with a shoulder at 19 to which is secured by soldering screwing or in any
other manner a tube 20 the bottom of the said tube 20 is provided with a bush 21
into which is screwed a plug 22, the space 23 enclosed between the outer tube 20
and the collar 13 constituting a reservoir for containing the lubricating material.
Through the lower part of the extension of the collar 13 we form an aperture 24
for admitting the lubricant to the spindle 18-Within the upper part of the
enlarged portion of the collar 13 we form an annular groove 25 which communicates
with the cavity or reservoir 23 by openings 26 formed through the collar 13 either
by drilling or other convenient manner such openings 26 being more clearly shown
in Fig. 6 which is a cross section taken on the line C D of Fig: 5-From an
annular groove 28 formed in the upper part of the flange 13* we form an
opening 27 communicating with the opening 26 by which lubricating material may
be supplied to the reservoir 23. By means of the plug 22 the lubricating material
may be removed from the reservoir 23 or in a manner similar to that described in
reference to Figs 1, 2, 3 and 4. By Figs 7 and 8 is shown another arrangement of
our invention Fig 7 being an elevation partly in section and Fig: 8 a plan thereof.
At 29 is the spindle rail upon which we mount a chamber or reservoir 30 upon
which we form a lug 31 through which and the spindle rail 29 passes a bolt 32
having a nut 33 by which the chamber or reservoir 30 is secured to the spindle
rail 29-The upper part of the chamber or reservoir 30 is formed with an end
piece 34 formed with which is a tube 35 one portion of such tube extending
npward above the top of the chamber or reservoir 30 the other portion thereof
passing into the interior of the chamber or reservoir-Within the upper part of
the tube 35 is placed a bush 36 and into the lower end of the said tube 35 which
is within the chamber or reservoir 30 we screw a footstep 37 which along with the
bush 36 supports the spindle 38. Into the lower part of the chamber or
reservoir 30 is screwed a bush 39 an extended part 39× of which passes through a
cylindrical aperture formed through the spindle rail 29-Within the bush 39 is
formed an annular projecting rib 40 forming a seating against which a washer 41
composed of leather cork or other suitable material is forced by means of a screwed
plug 42 capable of being screwed within the bush 39. The washer 41 is secured to
the plug 42 by means of a set screw 43 tapped into the said plug 42-The annular
space 44 enclosed between the cylindrical casing 30 and the tube 35 forms a cavity
or reservoir for containing lubricating material as indicated by the short horizontal
lines such lubricating material being admitted to the spindle 38 through an opening
formed through one side of the tube 35-The above described arrangement admits
of the lubricant being brought to within a short distance of the bush 36-In order
to form the opening 45 through the side of the tube 35 we first form an aperture
through the side of the reservoir 30 which we afterwards close by means of a
plug 46-When it is desired to remove the lubricant from the chamber or
reservoir 30 the plug 42 is turned in the direction for unscrewing and thus
withdrawing the washer 41 from contact with the annular projecting rib or
seating 40 the lubricating material will then be enabled to pass down between the
circumference of the washer 41 and the inner surface of the bush 39 the washer 41

page_text: being made of less diameter than the interior of the bush 39. From the lower end
of the plug 42 extending upward but not through the entire length of the said
plug we form an opening 47 communicating with which and the outer circum-
ference of the plug 42 we form openings 48 (two only of which show in the
Drawing) from these openings we form within the plug 42 grooves or ducts 49
which communicate with the annular cavity around the washer 41 so that when
the washer 41 is withdrawn from contact with the annular seating 40 the
lubricating material will be allowed to escape from the chamber or reservoir 30
and pass down the grooves or ducts 49 thence through the apertures 48 and will
escape by the opening 47 formed within the plug 42--After screwing the plug 42
tight against its seating lubricating material may be introduced into the
chamber 30 through the aperture 50-We would here remark that the chamber or
réservoir 30 and part which is subsequently drilled or bored to form the tube 35
we propose to form as one casting, the opening in the lower part thereof into
which is screwed the bush 39 enables the core or sand to be removed from the
cavity or reservoir 44 after such casting has been performed-For simplicity we
have shown in Figs: 1 and 5 the reservoirs or cavities for containing lubricating
material as provided with screwed plugs but it will be readily understood that the
arrangement of plug and washer as described in reference to Fig 7 might be
substituted for the screw plug or any ordinary stop cock could be used for the like
purpose It will be seen from the above described arrangements that the
lubricating material may be removed from the cavities or reservoirs in which it is
contained without interfering with the working or adjustment of the spindle-
Fig: 9 shows a further modification of our Invention the chamber for containing
the lubricating material being in this instance placed below. the spindle rail 51.
At 52 is a tube or collar within which is a spindle 53 capable of being freely
revolved therein A portion of the tube 52 we form taper so as to fit within an
opening formed in the chamber 54. The chamber 54 is secured to the spindle rail 51
by means of a bolt 55 provided with a nut 56 the head of the said bolt passing by
means of a slot 57 into a recess 58 formed upon the chamber 54. The lower part
of the chamber 54 is provided with a plug 59 similar to that described in reference
to Fig 7-In the upper part of the chamber 54 we form an aperture 60 by which
lubricating material may be introduced into the interior of the chamber 54. The
removal of the lubricating material from the chamber 54 may be effected as
previously described in reference to Fig 7-Since filing our Provisional Specification
we find that the portion of our invention which refers to forming the nut for
securing the collar carrying the spindle to the spindle rail as a reservoir for
containing lubricating material is not new-we therefore lay no claim thereto.
Having thus described and ascertained the nature of our said Invention and the
manner in which the same is to be performed I desire it to be understood that we
claim as secured to us under the above in part recited Letters Patent-
The use of a reservoir or cavity from which the lubricating material may be
removed without interfering with the working or adjustment of the spindle
substantially in the manner hereinbefore shewn and described.
In witness whereof. I the said John Dodd have hereunto set my hand and
seal this thirteenth day of July in the year of our Lord one thousand
eight hundred and eighty two.
