FREDERICK TOWNS POLLARD, 52 Bruce Street, New Wortley, Leeds, in the County
of York, Machine Joiner, and RICHARD ATKINSON, 61 Church Street Kirkstall, Leeds,
in the County of York Cloth Drawer, do hereby declare the nature of this invention
to be as follows:-
In actuating the dabber in Nobles and similar Combing Machines, by means of a
crank, or by means of an eccentric, revolving in a recess, hole, or aperture in the
dabber, having straight, parallel, and adjustible surfaces, the said surfaces made of
wood or metal, or they may be made of both wood and metal, and adjustible vertically,
or in a line with the motion of the dabber.
The whole working in a box or case with a hollow bottom, to receive and hold the
oil which is thrown off, or drops from, the parts lubricated, the said hollow bottom
fitted with an overflow pipe.
Besides lubricating through the surfaces in contact with the crank pin or with the
eccentric, we have a novel way of lubricating, by admitting the oil at the centre of
the crank shaft, or eccentric shaft, it is carried forwards by the revolution of the said
shaft, through an oil passage, to the crank pin, or to the surface of the eccentric, also
there is a recess in the crank pin, and in the eccentric, into which tallow or oil is
placed, and is thrown through a hole to the surface, by revolving.
In the case of the double dabber, for which letters patent were granted to one of us
(Fredk. T. Pollard) No. 502 in the year 1884 we actuate the two dabbers by means of
a crank each, or an eccentric each, or one by a crank, and the other by an
eccentric, the said pair of dabbing motions being driven by one belt, or a seperate
belt may be used for each motion, the said motions being either virtical, or turning on
a centre.
Each of the dabbers has a depressor, to operate on the fibre before being pressed
into the teeth of the combs, these depressors may either form part of the brush as at
present, or be seperate from the brush, and have a seperate adjustment.

up by layers of wood, metal, or any other suitable material, on the top of the brush.

COMPLETE SPECIFICATION.
Improvements in Nobles' and similar Combing Machines.
FREDERICK TOWNS POLLARD, 52 Bruce Street New Wortley, Leeds, Machine
Joiner, and RICHARD ATKINSON 61 Church Street Kirkstall Cloth Drawer 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 improvement consists in actuating the dabber in Nobles and similar Combing
Machines, by means of a crank, or by means of an eccentric, revolving in a recess,
hole or aperture in the dabber, between straight parallel and adjustible surfaces, the
said surfaces being made of wood or metal, or they may be made of both wood and
metal, or any other suitable material, and adjustible vertically, or in the same direction.
as the motion of the dabber.
The whole working in a box or case having a hollow bottom, to receive and hold
the oil which is thrown off or drops from the parts lubricated, the said .hollow.bottom
fitted with an overflow pipe.
Besides lubricating through the surfaces in contact with the crank.pin or with. the
eccentric, we have another method.
By admitting oil at the centre of the crank shaft or eccentric shaft it is carried
forward by the revolution of the said shaft through an oil passage in the shaft to
the crank pin or to the surface of the eccentric also there is a recess.in the crank
pin or in the eccentric into which tallow or oil is placed and is thrown through
a hole to the surface by revolving. The lubricating is continuous by catching the
oil which drops from the overflow pipe and pouring it into the vessel K to drop
again into the oil cup near the centre of the crank.or eccentric spindle.
What is taken off the thickness of the brush underneath by the wearing of the
bristles we make up on the top of the brush by layers of wood, metal, leather,
india rubber or any other suitable material between the brush and dabber. foot.
The dabber foot has a seperate adjustment being either secured to one side of the
dabber. with bolts or screws or screwed on..to or into the dabber underneath, and
the depressor is secured to the dabber foot instead of to the brush as at present.

page_text: Besides the dabber depressor we have a stroker depressor which revolves and is
seperate from the dabber and grooved or fitted with pins, brushes, leather, or plates.
In the case of the double dabber for which letters patent were granted to one of us
(Fredk. T. Pollard) No. 502 Jan. 3rd 884 we actuate the two dabbers by means of
a crank each or an eccentric each or one by a crank and the other by an eccentric
and connect the crank or the eccentric of a dabber on one side of the machine to
the crank or the eccentric of a dabber on the other side of the machine by means
of a cross shaft from one to the other, the crank or eccentric secured to one end
of the cross shaft projecting from the shaft the contrary way to the crank or
eccentric secured to the other end of the shaft so that they balance each other and
that when the dabber on one side of the machine is descending the dabber on the
other side of the machine is ascending.
The two dabbing motions on one side of the machine being driven by one belt
and the two on the other side of the machine by another belt or seperate belts
may be used for each dabber or the cross shaft may be actuated by a belt from
the driving shaft giving motion to two dabbers one on each side of the machine
and seperate belts used for each of the other two dabbers. The depressing of the
fibre before being dabbed by the brushes being done by both dabbing motions on
one side of the machine and by both on the other side of the machine.
The cross shaft may also be used in the case of the ordinary single dabber on each
side of the machine.
The dabbing motions may either be vertical or turn on a centre.
DESCRIPTION OF DRAWINGS.
A crank-B eccentric.-( recess in dabber D dabber.-E depressor.-F box or
case with hollow bottom in which dabber works G overflow pipe.-H oil passage in
crank or eccentric shaft.-K vessel from which oil drops into the cup below. to..
lubricate the crank or eccentric.-I layer of wood,-metal etc. M dabber foot.-
N cross shaft. P labber turning on a centre.-E 2 stroker depressor.
The dabber being actuated between parallel surfaces has a plumb left and the
surfaces being adjustible vertically present the same straight surface to the crank pin
or to the eccentric when from time to time they need adjustment.
By using the crank it may be more easily repaired and take up less room than the
methods now in use.
Wood being used in the surfaces the oil will be retained longer than by being madle
entirely of metal.
All the dabbing mechanism being encased in a box with an inlet and outlet oil
may be freely fed into the box and on the parts requiring it whilst the dabber is
in motion without being wasted or thrown about and is-self lubricating by the
revoluton of the oil passage.
By adjusting the brush with packings between it and the dabber. foot the dabbing
motion is simpler and lighter.
As the brush wears much faster than the depressor a seperate adjustment is desirable.
The stroker depressor helps forward and partly cleans the fibre and is a continuous
motion. These depressors keep the fibre down so that a shorter stroke of the dabber
will suffice.
By using the dabber which turns on a centre it may be run at a greater speed

surfaces in the dabber.
2nd. A cross shaft seperate from the driving shaft to connect a dabber on one side
of the machine to a dabber on the other side of the machine.
3 d. A revolving oil passage and continuous lubricating.
