"IMPROVEMENTS IN APPARATUS FOR LUBRICATING THE SPINDLES EMPLOYED IN
MACHINERY FOR SPINNING, DOUBLING, OR TWISTING FIBROUS MATERIALS, AND
WHICH IMPROVEMENTS ARE ALSO APPLICABLE IN PART OR ON THE WHOLE TO THE
ROTATING AND SLIDING PORTIONS OF OTHER MACHINERY."
My Invention relates to a new and more efficient mode of effecting the lubrication
of the foot steps and bolsters to be used in machinery for spinning, doubling, or
twisting fibrous materials, which improvements are also in part or on the whole
applicable to the purpose of lubricating the bearings or supports of rotating shafts,
whether the same work in a vertical or horizontal position, and also to the sliding
parts of reciprocating machinery.
The nature of my Invention and the mode of its application will be further
understood from the following description in the which I commence with the
bolsters or bearings which support the spindles used in machinery for spinning,
doubling, or twisting.
At the top or upper ends of the bolster I form a flat bottomed recess or cavity
(cylindrical by preference) in which I place a check plate or thin plate of metal
or other durable substance, which is more or less of the same form as the recess,
but entirely independent of it. The lower surface of the check plate is flat or
nearly so, corresponding with the flat or other surface of the recess, and at or about
the middle of the check plate is a short tube of the same height, or thereabouts,
as the rim or edge round the recess. Through the hole in the cheek plate and the
tube the spindle passes, and the hole is sufficiently large as to render the check
plates entirely free or independent of the spindle. When the apparatus is in use
oil or other fluid lubricant is put into the recess, from which it has no exit except

page_text: by passing betwixt the lower surface of the check plate and the upper surface of
the recess.
Betwixt these two surfaces the lubricant insinuates itself till it comes
to the spindle, which is thereby efficiently and economically lubricated.
In cases where the nature of the lubricant requires it 1 regulate the size and
weight of the check plate to suit the circumstances of the case.
The application of the apparatus to the foot steps of spindles is the same as that
described, except that the foot step is not perforated through but supports the
spindle in the usual manner.
To vertical rotating shafts I apply my Invention in the same manner as described
for spindles.
For lubricating horizontal shafts, and for lubricating the slides of reciprocating
motions, I construct my Invention in the same manner, with the exception that in
these cases I do not generally use a short tube about the middle of the check plate
but use a short cylinder of solid material instead.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Hartcliffe in the Great Seal Patent Office on the 11th
November 1876.

"IMPROVEMENTS IN APPARATUS FOR LUBRICATING THE SPINDLES EMPLOYED IN
MACHINERY FOR SPINNING, DOUBLING, OR TWISTING FIBROUS MATERIALS, AND
WHICH IMPROVEMENTS ARE ALSO APPLICABLE IN PART OR ON THE WHOLE TO THE
ROTATING AND SLIDING PORTIONS OF OTHER MACHINERY."
My Invention relates to a new and more efficient mode of effecting the lubri-
cation of the bolsters and foot steps used in machinery for spinning, doubling, or
twisting fibrous materials, which improvements are in part or on the whole
applicable to the purpose of lubricating the bearings or supports of rotating shafts,
whether the same work in a vertical or horizontal position, and also the sliding
parts of reciprocating machinery.
In order to make the nature of my Invention and the mode of its application
more clearly understood, I have hereunto annexed a Sheet of Drawings to which
the following description relates, and in which the same letters or figures of reference
indicate the same parts.
Fig. 1 represents a mule spindle to which my Invention is applied for the
lubrication of the bolsters and foot steps. To commence with the bolster; at the
top or upper end I form a flat bottomed recess or cavity a, a, (this cavity I prefer
to be of a cylindrical form. In this I place a check plate b, b, which consists of a
thin plate of metal (or other suitable substance) which is more or less of the same
form as the recess a, a, but is entirely independent of it. The lower surface of
the check plate b, b, is flat or nearly so, corresponding with the flat or other surface
of the recess (t, d. At or about the middle of the check plate is a short tube c, c,
of the same height or thereabouts as the rim or edge round the recess. Through
the hole in the check plate and tube the spindle passes, and the hole is sufficiently
large to render the check plate entirely free and independent of it. The tube c, c,
Ins projecting from it a piece of metal which serves as a cover, and nearly fills
the recess a, a, and so prevents dust, &c. from entering into it. When the apparatus
is in use, oil or other fluid lubricant is put into the recess, from which it has no
exit except by passing betwixt the lower surface of the check plate and the flat
or other surface of the recess. Betwixt these two surfaces the lubricant insinuates
itself til it comes to the spindle, which is thereby efficiently and economically
lubricated.
In case where the nature of the lubricant requires it I place a piece of felt or
similar substance betwixt the two surfaces, and also regulate the size and pressure
of the check plate to suit the circumstances of the case.

page_text: With respect to the foot of the spindle the lubricating apparatus is precisely
similar to the above, the only difference being that the foot step is not pierced
through.
Fig. 2 represents the application of my Invention to the purpose of lubricating
the bolsters and foot steps of throstle spindles. As the mode of effecting this is
precisely similar as described for the mule spindle (ns will be seen on inspection
of the Drawing) such variations in the construction only being made as the nature
of the case requires) no further explanation will be necessary.
Fig. 3 represents the application of my Invention to the bolsters of bobbin and
fly frames. In this case as the motion which drives the bobbin is entirely inde-
pendent of the spindle, so must the lubricating apparatus be somewhat varied in
construction so as to answer the purpose of lubricating both the bobbin motion
and the spindle. This will be understood from the Figure (where it is shewn in
section) and the following description:-d, d, portion of the spindle; e, e, portion
of the bush, attached to the lifting rail (through which the spindle passes, shewn
also in section); f, f, section of the bobbin pinion which turns on the outside of
the bush. At the top or upper end of the bush e, c, is fixed the lubricating
apparatus g, g; this is nearly of the same form as that described as applied to the
bolster of the mule spindle, Fig. 1, but is necessarily required to be more of an
enlarged annular shape, and also as it has to effect the lubrication both of the
spindle and the bobbin pinion, so spaces or holes and are left open, through
which the lubricant exudes on passing the check plate, and thus effects the lubrication
of both the surfaces.
Fig. 4 represents my Invention as applied to the lubrication of the bearings of
horizontal shafts; h, h, recess or cup for holding the lubricant; i, i, the check
plate formed as before shewn; k, k, projecting piece attached to the check plate
and serving as a cover to keep out dust and prevent it from contaminating the
lubricant, l, a rod passing through the check plate and has its lower end resting
on the bearing to be lubricated, and thus serving as a conductor to the lubricant
ns it exudes from betwixt the lower surface of the check plate and the surface of
the recess.
Fig. 5 represents my Invention as applied to a crank pin or sliding motion.
m, m, the cup or receptacle for holding the lubricant; n, n, the check plate, which
in this case is not furnished with a short tube, but has a short cylinder of metal
instead. Below the check plate projects a short spindle, which serves to guide the
lubricant through the aperture o to the point where it is required. p, cover to
secure the lubricant from dust and dirt. It screws on the top of the cup m, m,
and is so arranged as to keep the check plate in its place (by means of the short
cylinder of metal before mentioned) during the motion of the crank or sliding motion.
Fig. 6 shows another application of my Invention. A cylinder of glass q, q, is
fixed betwixt a top piece 1, 2, and bottom piece of metal 8, 8. The top and bottom
pieces are combined and held together by means of a short wire or piece of metal,
which has screw threads at both ends, and being screwed into both the top piece
and bottom piece holds the glass cylinder q, q, betwixt them, the joints at the top
and bottom of the glass cylinder being made tight by means of cement or other-
wise; u, u, a screw nut on the wire t, t, the use of which is to keep the check
plate in its place and press upon it as may be necessary to regulate the amount
of lubricant to be delivered. In other respects the action of the check plate is the
same as already described. The top piece 1,, has a groove round it at the outside,
and is furnished with a hole for supplying the lubricant, and a short tube to allow
the passage of the air. By this arrangement the quantity of lubricant in the
apparatus is apparent, and inay be regulated.
Fig. 7 is another view of the application of my Invention not differing from
what has already been shewn, excepting that it has the addition of a short
tube v, v, projecting from the bottom of the recess into the interior of the check
plate, and acts as a further check and prevents the lubricant from being lost in case
of the check plate being lifted for any purpose.

page_text: Fig. 8 is another view, not differing from that shewn in Fig. 7, except that the
tube 2, w, passes entirely through the check plate, and that the lubrication of
the spindle or shaft which passes through the bolster and the tube w, w, is effected
by means of one or more holes bored through the tube above the bottom of the
recess.
It will be seen that the various Figures referred to are for the most shewn in
circular section, and it must be understood that I do not confine myself to the
precise details and arrangements of my Invention as shewn in the description and
the Drawings, as these may be varied, but that what I do claim as new and of my
Invention is as follows:-The application and adaptation of the check plate in
combination with the other parts of the apparatus, for the purpose of lubricating
the moving parts of machinery in an efficient and economical manner as herein set
forth and described.
In witness whereof, I, the said William Hartcliffe, senior, have hereunto set
my hand and seal, this Fourth day of November, in the year of our Lord
One thousand eight hundred and seventy-six.
