I GEORGE DIXON of Servia Terrace Camp Road Leeds in the County of York,
Mechanic, do hereby declare the nature of this invention to be as follows:-
The object of my Improvements is to ensure greater steadiness of running, more
efficient lubrication, and the proper taking up from time to time of the wear of
mechanism employed for actuating the dabbing brushes of combing machines.
My improvements consist of a circular box enclosing the eccentric and working
parts of such mechanism, in such a manner that these latter are practically running or
working surrounded by or in a bath of oil, the box being kept more or less completely
filled with oil. The main part of the box is cast with two brackets, by means of
which it is attached to the upright pillar of the combing machine; and between
these brackets is fitted the driving or rather driven pulley giving motion to the rest
of the mechanism. The axle or shaft carrying the pulley is turned taper or conical
where it passes through the circular box and through the bearings in the back and
front of the box; the taper being continuous and in one direction narrowing to the
front. On the inside nearest to the back of the box is a circular disc nearly of the
same diameter as the interior of the box, and having a vee circular groove cast
eccentrically therein, the wider part of the groove facing to the front of the box.

Improvements in Mechanism for Actuating the Dabbing Brushes of
Combing Machines.
I GEORGE DIXON late of Servia Terrace Camp Road now of Meanwood Road
Leeds in the County of York Mechanic 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 :-
The object of my Improvements is to ensure greater steadiness of running, more
efficient lubrication, and the proper taking up from time to time of the wear of
mechanism employed for actuating the dabbing brushes of combing machines.
My Improvements consist of a circular box enclosing the eccentric and working
parts of such mechanism, in such a manner that these latter are practically running or
working surrounded by or in a bath of oil, the box being kept more or less filled
with oil. The main part of the box is cast with two brackets by means of which it is
attached to the upright pillar of the combing machine, and between these brackets is
fitted the driving or rather driven pulley giving motion to the rest of the mechanism.
The axle or shaft carrying the pulley is turned taper or conical where it passes
through the circular box and through the bearings in the back and front of the box,
the taper being continuous and in one direction narrowing to the front. On the
inside nearest to the back of the box is a circular disc nearly of the same diameter as
the interior of the box, and having a V circular groove cast eccentrically therein, the
wider part of the groove facing to the front of the box. Fitting in and projecting
somewhat beyond this groove is a steel or phosphor bronze annulus or ring, having a
pin attached to one part thereof. The annulus or ring and the eccentric groove are
fitted together vee-wise in order that they may still accurately fit each other even
after considerable wear. The flat front side of the annulus or ring bears against the
inner face of the cover or lid of the circular box, and in this cover is cast a
rectangular radial recess or slide race, in which latter is fitted a block attached to a
spindle or rod passing through a stuffing box at the outer top end of the radial recess.
The just mentioned block is provided with a hole or socket in which fits the pin
attached to the above mentioned annulus or ring. It will be evident that a rotation
of the circular disc containing the eccentric vee groove will cause a reciprocating
motion of the block and the spindle or rod. The recess or slide race is cast on the
cover in a vertical position, so that the motion of the spindle or rod is a vertically
reciprocating one. The spindle or rod is attached by means of a cross piece to the
dabbing brush sliding piece, which is guided vertically between the outer planed part
of the before mentioned slide race casting and vee'd plates bolted to the cover of the
circular box.
The front flange of the circular box may be provided with a circular recess, in the
outer or front part of which is fitted a circular tongue, turned on the inner side
of the face of the box lid or cover. The bottom part of the groove may be filled
with hemp or other suitable packing, to prevent the escape of oil from the box. Two
annular washers fitted in circular recesses in the back and front of the box, prevent the
escape of oil along the axle, and any oil carried along the axle from the interior of
the box as far as these packing washers, is returned back to the interior along holes
drilled close to the outer circumference of the circular recesses.
The front part of the tapered axle is screwed, and on this fits a small hand wheel

page_text: having a central tapped hole in the boss, so that by screwing up the hand wheel any
wear of the spindle and mechanism may be taken up.
In the case of dabbing brush mechanism which is boxed up, it is often very
difficult to ascertain whether any oil is still retained for lubrication, and there is
consequently a liability of such mechanism running hot before the deficiency of oil is
found out. To prevent this I provide a glass gauge or indicator, and attach the
same to the outside of the circular box in such a position, that so long as sufficient
oil is present to ensure efficient lubrication, this is indicated by the oil being thrown
off by centrifugal action between the glasses of the indicator, or by the height or
level at which the oil stands within the glass.
And in order that my Invention and the manner in which the same may be
performed may be more readily understood, reference is given to the accompanying
drawings and to the letters and marks thereon. in which Fig. 1 is a front elevation,
Fig. 2 a vertical section, Fig. 3 a horizontal section, and Figs. 4, 5, and 6 details to
be hereafter referred to.
a is a box preferably circular in shape and the cover of the same, containing
between them the working parts of the inechanism. The box a is usually cast in one
piece with the lugs or brackets c, by means of which it is attached to the pillar of
the combing machine. d is the main spindle or axle, which passes through the two
bosses e and ƒ cast or formed respectively on the box a and the cover b. The spindle
or axle d is formed taper over both parts which fit or pass through correspondingly
tapered holes in the bosses, the direction of the taper over both parts being towards
one and the same (i.e. the front) end of the spindle. On the back end of the spindle
which projects beyond the boss e is keyed the pulley g, which is further secured by
means of the nut and by making this part of the axle or spindle taper. In the
inside of the box a is placed the circular disc i see Fig. 4, keyed on to the axle or
spindle d, and having on the front face an eccentric or cam groove V shaped in cross
section. Fitting in this groove is an annulus or ring or half ring j, preferably of the
section shown in Fig. 2 in full black. If a cam groove instead of an eccentric groove
is formed in the front face of the disc i, then a runner or sliding piece of suitable
shape is employed instead of the annulus or half ring j. The annulus or half ring j is
preferably formed of steel or phosphor bronze, and bears with its front face against
the inner side of the cover b. As previously mentioned the groove in the disc and
the annulus or half ring where they fit together are formed vee-wise, in order that
they may still accurately fit even after considerable wear. A vertical rectangular
radial recess or slide race k is cast on the cover b, and which is open throughout its
whole length on the inner side to the interior of the box a. (See also Fig. 5 which
is a section of the cover b on line A A, Fig. 1.) In this recess or slide race is fitted a
slide block attached to or formed on the lower end of the vertical spindle m, which
latter passes through a stuffing box a closing the upper end of the recess or slide
race k. The above mentioned block is provided with a hole or socket in which fits
the pin o attached to or preferably formed in one piece with the annulus or half ringj.
It will be evident that a rotation of the circular disc i will impart a vertical
reciprocating movement to the block and the spindle m. The spindle or rod m is
attached at the upper end in an adjustable manner by means of the nut p and the
slot r, formed in the cross-piece of the upper end of the dabbing brush slide or
carriers, which slide is guided vertically between the bevelled inner sides or edges
of the plates & bolted to the cover b.
The boss e of the box a and the boss of the cover 6 are provided at their outer
ends with circular recesses in which are placed the annular washers u, the inner
diameter of these corresponding with the diameters of the spindle at these parts,
whilst the outer diameters are considerably less than the diameters of the recesses.
Inclined holes or passages lead from the bottom of these recesses to the interior of
the box or case a.
By this arrangement any oil which may have travelled along the
axle d from the interior of the box a is thrown off by the loosely fitting washers u, and
is drained from the bottom of the recesses back into the interior of the box a along

page_text: the passages, instead of forward GO the outside of the bosses and dropping
therefrom.
The front part of the tapered axle d is screwed, and on this is fitted a small
handwheel w having a central tapped hole in the boss, so that by screwing up this
handwheel any wear of the mechanism is taken up. It is on this account that the
taper of the axle d in both bosses is in one and the same direction.
2
The lower part of the box a is kept more or less filled with oil as shewn in Fig. 2,
so that the lower part of the disc is constantly running in oil, and owing to the
speed at which the disc rotates the oil is constantly being thrown off from the
circumference so as to thoroughly and automatically lubricate the slide race k, pin o,
the annulus or half ring j, and the spindles d and n.
1
In the side of the box a preferably the underside, I provide a passage a leading
from the lower part of the interior of the box. This passage terminates at the
outside in a pap or lug, into which is screwed one end of the connecting pipe y.
The connecting pipe y screws into or forms part of the lower termination of the ring z.
This ring is recessed on both sides, (see Fig. 6 which is a cross section on line (D
Fig. 1) so as to receive the packing rings a¹, the glass sides b', and the inner sides of
the closing rings c', which latter are held together by means of screwed pins or
bolts de is an air hole provided in the top of the ring, and f¹ is a plugged hole
from which the plug can be unscrewed, so as to drain the oil from the interior of the
hox a when desired. It will be evident that so long as the level of the oil in the
box a stands between the lines 1, 1, and 2, 2, this level will be indicated by the level
of the oil in the chamber between the glasses b₁₁. It will be readily understood that
the shape of the chamber between the glassos 6' 6' is immaterial, the chamber itself
even may be formed as a glass cylinder, also that it may be attached close to the side
of the box a at any height, if the aperture or passage connecting it with the interior
of the box is sufficiently short and large in section, so that the presence of oil in
sufficient quantity to properly lubricate the mechanism is indicated by the splashing
of the oil in the chamber between the glasses as it is thrown off from the edge of the
rapidly rotating disc i.
I wish it to be understood that I do not limit myself to the precise forms or
arrangements of parts described and shewn, as these may be somewhat varied
without departing from the nature of my said Invention; as for example the
revolving circular disc i may be employed separately for lubricating purposes, where
other mechanism is employed for producing and imparting the reciprocating up and
down motion to the dabbing brush slide; also the taper of both journals of the axle
or spindle may be towards the back instead of the front; but 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 what I claim is :
1° The combination of cam-or eccentric disc i, sliding piece or ring j and pin o
with the slide block guided in a vertical slide race or guide substantially as and for
purpose herein set forth.
the
26 The employment of a disc, rotating within the box enclosing the working parts,
for the purpose of automatically lubricating the enclosed mechanism in the manner
herein set forth.
3° The spindle or axle d having conical journals, the taper of both of these being in
one and the same direction, said journals running in corresponding conical bearings,
and the combination therewith of the tapped hand wheel to for the purpose of taking
up any slack or play due to wear.
4° The means substantially as described and shewn for preventing or diminishing
the flow of oil along the axle or spindle to the outside, consisting of recesses, loosely
fitting washers u and drain channels v.
5º A passage through the outside or walls of the box enclosing the working parts,
communicating and in combination with a chamber having glass sides or side, for the
purpose of ascertaining the presence or otherwise of oil within the said box.

page_text: 6° The general arrangement and combination of the various parts forming and in
connection with my improved apparatus for actuating the dabbing brushes of combing
machines substantially as herein set forth and shewn.
