PROVISIONAL SPECIFICATION,
Improvements in Dabbing Motions for Noble and other Combing
Machines.
I, JONATHAN EDWARD STEPHENSON, Managing Director of John Perry, Limited,
of Shipley Fields Mill, Shipley, in the County of York, Machine Makers, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in dabbing motions for Noble and
other combing machines, and its object is to reduce the friction of certain of
the working parts as well as facilitate lubrication.
For this purpose I employ a ring or annular piece fitting the crank pin or
eccentric and also fitting the connecting rod or part reciprocated thereby so that
it.forms a loose bearing piece between. the two and the friction is more or less
divided between the inner and outer peripheries of the ring or annular piece.
Balls or rollers may be placed in suitable recesses in the peripheries of the ring
or the faces against which they bear.
A curved tube is fitted to the bottom of the crank bearing of the connecting
rod adapted at each stroke to dip down into the oil well below and scoop up the
oil into the bearing. Lubricating holes may be made in the top of such bear-
ing. A baffle piece may be introduced to prevent the tube and rod throwing
the lubricant out of the top of the box or case.
I may provide a large bearing disc or, collar on the crank shaft to engage
a bearing or recess adjacent to. and concentric with the ordinary bearing.

Improvements in Dabbing Motions for Noble and other Combing
Machines.
I, JONATHAN EDWARD STEPHENSON, Managing Director of John Perry, Limited,
of Shipley Fields Mill, Shipley, in the County of York, Machine Makers, 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:—
This invention relates to improvements in dabbing brushes for Noble and
other combing machines, and its object is to reduce the friction of certain of
the working parts as well as facilitate lubrication.

page_text: To fully describe my invention reference is made to the accompanying sheet
of drawings, forming a part of this specification, in which similar figures of
reference indicate corresponding parts in each of the views.
Figure 1, represents a front view partly in section of a dabbing motion made
in accordance with my improvements.
Figure 2, is a cross section of the same.
Figure 3, is a view on a larger scale of the crank and connecting rod.
Figure 4, is a plan view of the same with the crank pin and connecting rod
shown in section on the broken line a, b Figure 3.
The brush slide 2 is fitted in guides in the usual way in the case 3 and is
connected by the stud 4 to the top 5 of the connecting rod 6. A ring or annular
piece 8 fits round the crank pin 9 and the lower end 10 of the connecting rod
is fitted over this ring so that it forms a loose bearing piece between the pin 9
and the connecting rod and therefore the friction is more or less divided between
the inner and outer peripheries of the ring.
Instead of the ring 8 closely fitting the pin 9 and the lower end 10 of the
connecting rod, balls or rollers 13 may be placed between the parts as shown
in the drawings.
A curved tube 15 is fitted in the crank bearing 10 of the connecting rod.
The crank rotates in the direction of the arrow Figure 1 and at each revolution
dips down into oil contained in the bottom of the case 3 and scoopes up the
oil and passes it into the bearing. A baffle piece 20 extends across the case 3
to prevent the tube throwing the oil out of the top of the case.
A leather or other suitable stroker 22, fixed on the spring arm 23 secured
to the side of the case 3 is provided to engage the side of the rod 6 during its
up stroke and rub back any lubricant that may have splashed on to it.
I may provide a large bearing 30 in the case 3 for the crank disc 31 to
revolve in.
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. In a dabbing brush, the combination with the crank pin and connecting
rod, of the ring fitting between them, substantially as herein shown and
described.
2. In a dabbing brush, the combination with the crank pin and connecting
rod having a ring fitting between them, of balls or rollers introduced between
said pin, ring and connecting rod, substantially as herein shown and described.
3. The combination with the connecting rod, of the tube 15, substantially
as herein shown and described and for the purpose specified.
4. The combination with the tube 15 of the baffle piece 20, substantially as
herein shown and described.
5. The combination with the crank disc 31 of the bearing 30 in the case.
Dated this 11th day of September 1899.
