PROVISIONAL SPECIFICATION.
Improved Machinery for Dressing the Surfaces of Rollers or
Cylinders used in Spinning and like Machines.
I, CHARLES RODOLPHE CLAD, of the firm of Gebr. Clad, Wool Combers and
Manufacturers of Machines, of Reichenbach i/V. in the Empire of Germany do
hereby declare the nature of this invention to be as follows:-
This invention consists in improved machinery for dressing the surfaces of
rollers or cylinders and principally those used as upper pressing cylinders in many
kinds of spinning machines.
These rollers are supported by their trunnions on inclined ways on the framework
of the machine one behind another so that the lowest of the rollers may be received
by a holder consisting of two circular disks with slots in their peripheries to receive
the trunnions of the rollers. This holder revolving intermittently in front of the
end of the inclined chute on which the rollers have been placed receives the latter
one by one in the said slots and carries them downward to the dressing cylinder
which operates on their surfaces, on each for a certain time. The rollers during
their passage from the chute to the dressing cylinder are held from falling out of
the slots by springs which also serve as brakes to the revolving holder. The
trunnions of the rollers so passing come in contact with wicks dipping into a
reservoir of oil by which means the trunnions are properly and sufficiently
lubricated without excess of lubricant.
The holder is revolved by lever and pawl operated by a tappet on a worm shaft
revolved by gear from the shaft of the dressing cylinder; this tappet also operates
to lift the lever by which each roller as it arrives over the dressing cylinder is
pressed thereon during the dressing. This dressing is applied to each roller as it
arrives in the proper position and is continued until the revolution of the tappet
revolves again the holder and lifts the pressing lever from the roller whereupon
the dressed roller is delivered to a suitable delivery chute and the next comes
under the action of the dressing cylinder.

Improved Machinery for Dressing the Surfaces of Rollers or
Cylinders used in Spinning and like Machines.
I CHARLES RODOLPHE CLAD of the firm of Gebr. Clad, Wool Combers and
Manufacturers of Machines of Reichenbach, i/V. in the Empire of Germany 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 consists in improved machinery for dressing the surfaces of rollers
or cylinders and principally those used as upper pressing cylinders in many kinds
of spinning machines.
These rollers are supported by their trunnions on inclined ways on the framework
of the machine one behind another so that the lowest of the rollers may be received

page_text: by a holder consisting of two circular discs with slots in their peripheries to receive
the trunnions of the rollers. This holder revolving intermittently in front of the
end of the inclined chute on which the rollers have been placed, receives the latter
one by one in the said slots and carries them downward to the dressing cylinder
which on their surfaces, on each for a certain time. The rollers during their
passage from the chute to the dressing cylinder are held from falling out at the
slots by springs which also serve as brakes to the revolving holder. The trunnions
of rollers so passing come in contact with wicks dipping into a reservoir of oil by
which means the trunnions are properly and sufficiently lubricated without excess
of lubricant.
The holder is revolved by lever and pawl operated by a tappet on a worm shaft
revolved by gear from the shaft of the dressing cylinder; this tappet also operates
to lift the lever by which each roller as it arrives over the dressing cylinder is
pressed thercon during the dressing. This dressing is applied to each roller as it
arrives in the proper position and is continued until the revolution of the tappet
revolves again the holder and lifts the pressing lever from the roller whereupon
the dressed roller is delivered to a suitable delivery chute and the next comes under
the action of the dressing cylinder.
In the drawings
Fig. 1 is a lateral view of the machine, Fig. 2 a plan thereof, Figs. 3 to 9 are
representations illustrating the process and the different parts of the machine.
The machine has two frame walls A. B. between which the rollers are put in to
slide down on the rails a. The lowest cylinder lies before the disks E F with
slits b, engages in the latter and is carried therewith on the intermittent revolution
of the disks. c are the retaining springs which act also as brake springs to prevent
backward moving of the disks during the returning of the pawl d.
The shaft of the rifling or dressing cylinder operates the cam shaft g the
tappet H of which moves the pawl lever d which oscillates at and also the lever J
against the effect of the spring m. The first lever J is lifted and kept in this
position until the upper lever d with its. pawl d has moved the disk EF so that
the axis of the next roller arrives underneath the cushion i of the lever J.
When the changing movement is completed and the tappet H has left the
rollerk of the lever J, the spring m pulls downs the lever J which presses
the roller to be dressed with its surface against the dressing cylinder G by the.
revolving machine of which the desired dressing (grooving, channelling or rifling).
is produced.
At the next changing movement the dressed roller is removed and the next roller'
comes under the action of the dressing cylinders.
For the oiling of the trunnions n of the upper cylinders without dropping of the
oil, an oil receptacle (lubricator) K is arranged between the frame walls with a
wick leading so that its upper end must necessarily be touched by each of the
axles of the rollers as they pass, each roller receiving as much oil as is needed for
the dressing process.
The machine may be constructed so as to be single or double acting or more.
In the drawing (see Fig. 2) a double acting machine is illustrated partly shown
in plan and partly in horizontal section.
With this machine it is also possible to eliminate the cylinders deficiently covered
with paper or parchment or other covering since after rifling or dressing such may
easily be recognised.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is
An improved machine for dressing the rollers such as are used in spinning or
like machines in which the said rollers are automatically fed to intermittently
moved slotted disks which carry the rollers successively underneath a pressing

page_text: lever J by which they are pressed against a rotary dressing cylinder g during a
required time whereafter the dressed roller leaves the machine substantially as set
forth.
