I, ROBERT ROGERS, of 56, Morton Road, New North Road, Islington, in the
County of Middlesex, Engineer, do hereby declare the nature of the said Invention,
to be as follows:-
This Invention relates to certain improvements in or applicable to frictional
arrangements for driving or actuating machinery, the Invention being specially
applicable to wire cotton and other winding machinery and to machinery where a
number of cylinders drums or like parts are arranged on a common shaft and
where it is required that provision should be made for accommodating uneven drag
tension or other causes productive of variation and want of uniformity so that such
parts may be driven by a source of motion common to them in accordance with
their separate requirements.
To this end, the Invention consists essentially in so mounting the cylinders
drums or other parts to be actuated on a shaft or. shafts as that they shall be able
to rotate thereon without being actuated by or actuating such shaft or shafts and
in causing such parts to be rotated or actuated in such a manner as to avoid all
such defects by frictional driving means constructed substantially as follows:-
Such improved means consist essentially of a boss or hub of wood iron or other
suitable metal or material which is squared or keyed on the driving shaft or is
otherwise positively driven and is formed with any convenient number of radiating
arms each of which preferably at the extremity thereof is adapted with a yielding.
or frictional cushion or pad.
.
Such devices may be so constructed and arranged as to actuate either one drum
or adjacent drums; in the former case the friction pads would be all arranged on
the same side of the arms which may be curved or shaped to accommodate the
shape of the side or part upon which they operate of the drum or part to be driven
which would be so mounted as to keep the cylinder in frictional contact with the
padded parts of the arm; and in the latter case the said pads would be arranged
on opposite sides of say alternate arms such arms being curved in reverse directions
to accommodate the adjacent drums or cylinders, the series of which would be
mounted on a shaft with one of such improved frictional driving devices between
each adjacent pair.

I, ROBERT ROGERS, of 56, Morton Road, New North Road, Islington, in the
County of Middlesex, Engineer, do hereby declare the nature of my said 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 certain improvements in or applicable to frictional
arrangements for driving or actuating machinery, the Invention being specially
applicable to wire cotton and other winding machinery and to machinery where a
number of cylinders drums or like parts are arranged on a common shaft and where
it is required that provision should be made for accommodating uneven drag
tension or other causes productive of variation and want of uniformity, so that such
parts may be driven by a source of motion common to them, in accordance with
their separate requirements.
To this end the Invention consists essentially in so mounting the cylinders
drums or other parts to be actuated on a shaft or shafts as that they shall be able
to rotate thereon without being directly actuated by or actuating such shaft or
shafts and in causing such parts to be rotated or actuated in such a manner as to
avoid all such defects herein before referred to by differential frictional driving
means constructed applied and operating substantially as hereinafter described.
An advantageous method of applying the Invention is illustrated on the accom-
panying drawings, in side elevation in Figure, 1, and in end elevation in Figure 2.
1 represents the cylinders or drums to be driven, and which are mounted loosely on
the shaft, 2, in such a manner as not to be rotated directly thereby, between a
fixed collar or abutment, 3, at the one end, and an adjustable collar or abutment 4,
at the other end, washers, 5, of leather or other suitable material being interposed
between the said abutments and the adjacent parts of the drums.
The improved driving device is constructed with a central part, boss or hub, 6,
of wood iron or other suitable metal or material, which is adapted with a feather, 7,
capable of sliding in a groove, 8, in the driving shaft, 2, or is otherwise adapted so
as to be positively driven by the shaft and so as to be capable of being adjusted in
any desired position thereon. From the boss or hub there projects any convenient
number of radiating arms, 9, each of which preferably at the extremity thereof is
adapted with a yielding or frictional cushion or pad, 10, of leather or other suitable
material and which may be rivetted or otherwise adapted to the arms as at, 11.
I prefer to forge the boss or hub and its radiating arms in steel, so shaping and
tempering the arms as that they shall have a desirable amount of resiliency or
springiness in them so that they may be caused to bear with more or less pressure
against the sides of the drums on which they act as may be desired.
Such devices may be so constructed and arranged as to actuate only one drum,
or so as to actuate adjacent drums, in the former case, the friction pads, 10, would
be all arranged on the same side of the arms, 9, which may be so curved or shaped

page_text: as to accommodate the shape of the side or part upon which they operate of the
drum or part to be driven which would be so mounted in the manner horein
described as to keep the cylinder in frictional contact with the padded parts of the
arms; and in the latter case, as in the modification represented on the annexed
drawings, the said pads would be arranged on opposite sides of preferably alternate
arms, such arms being curved in reverse directions to accommodate the adjacent
drums or cylinders, the series of which would be mounted on the shaft, 2, with one
of such improved frictional driving devices between each adjacent pair.
At its end, 12, the shaft is screw threaded and adapted with a nut and
lever, 13, or is otherwise equivalently provided so as to afford a means of adjusting
the pressure of the driving arms, 9, upon the adjacent drums as may be desired.
14, represents a set screw for screwing the nut and lever, 13, in the position
desired.
15, represents a driving pulley.
According to another modification, the device may be made of a disc-like
formation, the pads, 10, or springs or other equivalent yielding frictional driving
parts being adapted to its opposite sides or faces.
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 application to machinery of the kind hereinbefore referred and for the
purposes specified of differential frictional driving appliances constructed applied
and operating substantially as herein before described:
2. The construction of frictional driving appliances with a boss or part adapted
to receive motion from the shaft on which it and the part or parts it is required to
operate are mounted and with extending arms or equivalent parts adapted to
impart differential motion to the parts required to be driven in accordance with
their separate requirements substantially as herein before described.
