A communication from abroad by JEAN JACQUES RIEGER, of Lure, Haute Saône, in
the Republic of France, Engineer.
I WILLIAM PHILLIPS THOMPSON, F.U.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323 High Holborn, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates more especially to those machines which are intended for
working and cleaning textile materials, and in which the cleaning or dividing organs
are provided with a metallic covering called saw blade (lame de scie.) which is
generally adapted in a helical groove formed on the peripheral surface and on the
whole length of the working barrel.
This arrangement, in addition to its high first cost does not allow of placing the
blades as near as is necessary for certain operations.
This invention has partly for its object to construct coverings which do not require
the cutting of any helical groove on the surface of the drum and permits of adapting
to the surface of the latter eight or ten layers or rows of blades per centimètre thus
constituting a great advantage for certain operations more especially the unburring of
wool.
The saw blade used is provided internally and externally with teeth; the internal
teeth, which may be of any shape whatever, have only for their object to render the
blade sufficiently flexible to enable it to be wound properly round the periphery of the
drum, the shape of the external teeth must on the contrary vary according to
the nature of the work and the use for which the apparatus is intended.
The thickness of the cross section of the blades is not uniform, it is greater at the
lower part than at the top, and this difference in the thickness of the top and bottom

maintained between the working portions of the blades after they have been wound on
the drum, one in intimate contact with the other.
The increased thickness of the lower part may be all on one side of the blade, but it
will he understood that it may be provided on both sides so as to form equal
projections, if thought preferable. The blades are fixed on the drum in the following
manner:
The outer surface of the drum is accurately turned and provided at one end with a
fixed washer secured thereto and at the other end with a movable washer whereby the
saw blades can be pressed tightly one against the other.
After having secured by means of a pin the first extremity of the blade to the fixed
washer this blade is wound on the drum, care being taken to press the sides one
against the other.
During this operation, the distance apart of the internal teeth being immaterial and
not corresponding to an exact division of the external circle, the hollow parts of this
tooth arrangement do not come exactly opposite each other but overlap each other;
this arrangement permits of connecting at intervals by means of soldering, the various
layers or bands of the saw blades which are thus in juxta-position.
These light solderings are sufficient to resist the natural elasticity of the blades
whilst they are being wound and facilitate greatly the operation; they also permit the
employment for the purpose of trimming a cylinder a certain number of blades placed
end to end, the extremities of which are simply connected with each other by means
of soldering.
When the winding is finished, the movable washer is brought against the end of
the drum and pressed tightly by means of screws arranged on its periphery, so
that the whole of the saw blades form but a toothed cylinder extremely solid and
resisting.
Instead of providing screws at the periphery of tho movable washer plate, the
latter
drum be provided with a boss which can be passed over the boss cast on the
The end of the latter boss may be provided with a screw thread and
a nut whereby the movable washer plate can be pressed tightly against the drum.
A set screw in the boss of the movable washer plate permits of the latter being
secured in position on the boss of the drum.
Any other suitable arrangement may be employed instead for the same purpose.
It will be understood that in the arrangement described in the foregoing for
the purpose of cleaning textile materials, the blades of varied thickness may be
replaced by two bands wound round the drum simultaneously one being higher
than the other. The higher one is provided internally and externally with teeth and
constitutes the working blade, the other one which is lower and thinner and is not
provided externally with any teeth, serves simply to maintain the required distance
between the working blades.

I WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E. of the Agency for Foreign
Patent Solicitors & Lord Street Liverpool and 6 Bank Street Manchester both in
the County of Lancaster and 323 High Holborn in the County of Middlesex, Civil
Engineer, 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:-
$6
This invention relates more especially to those machines which are intended for
working, cleaning or tearing textile materials, and in which the cleaning or dividing
organs are provided with a metallic covering known as saw blade," which is
generally adapted to a helical groove formed on the periphery of the working barrel
throughout its length.
This arrangement, in addition to its high first cost, does not allow of the blades.
being brought as close together as is necessary for certain operations.
This invention has for-its object the construction of coverings which do not require
the cutting of a groove on the surface of the drum or harrel, and which permits
of the adaptation to the surface of the latter, of eight or ten layers or rows of
blades per centimètre. This is a great advantage in certain operations, more especially
in the operation of removing burrs from wool.
The accompanying drawings show the invention as applied to the drum of a
cleaning apparatus.
Figure 1 is a full sized view, part in elevation and part in section, of a segment
of a card cylinder on which the new saw blade is wound.
Figure 2 is a longitudinal section, on a smaller scale, of the same cylinder with its
metallic covering.
-
Figure 3 is a variation in the method of fixing the metallic covering on the surface
of the drum.
The saw blade used is provided internally and externally with teeth, as seen in
Figure 1. The internal teeth a', which may be of any shape whatever, are only
provided with the object of rendering the blade sufficiently flexible to enable it to be

page_text: wound properly round the periphery of the drum. The shape of the external
teeth a must, on the contrary, vary according to the nature of the work and the
use for which the apparatus is intended.
The blade is made of two thicknesses, as shown in the transverse section in
Figure 1. The lower part is thicker than the upper part, and this difference in
thickness, which may be as small as desired, determines the precise distance to be
maintained between the working portions of the blades after they have been wound
on the drum, in intimate contact with each other.
In the arrangement shown in Figure 1, the increased thickness of the lower part
may be all on one side of the blade, but it will be understood that it may also form
projecting surfaces on both sides of the blade, if thought preferable. The blados
are fixed on the drum in the following manner.
As may be seen in Figure 2, the outer surface of the druin A is accurately turned
and provided at one end with a fixed washer B, and at the other end with a movable
washer C. whereby the saw blades can be pressed tightly one against the other.
After having, by means of a pin, secured one extremity of the blade to the fixed
washer B, the blade is wound on the drum A, care being taken to press the coils one
against the other.
During this operation, the pitch of the internal teeth being immaterial and not
corresponding to an exact division of the external circumference of the cylinder, the
hollow parts of the tooth arrangement do not come exactly opposite each other, but
-overlap each other, as is shown in dotted lines on the left hand side of Figure 1. By
this arrangement the various layers or bands of the saw blades, which are thus in
juxtaposition, may be connected at intervals by means of points of solidering h.
This slight amount of solder is sufficient to resist the natural elasticity of the blades
whilst they are being wound and greatly facilitates this operation. It also permits of
the employment for the covering of a cylinder, of a certain number of blades placed
end to end, their extremities being simply connected to each other by means of
soldering (Figure 1).
When the winding is finished, the movable washer C is placed against the end of
the drum, and screwed up tightly by means of screws D arranged near its periphery,
so that the whole of the saw blades forms one toothed cylinder, extremely solid and
rigid.
"In the modification shown in Figure 3, the movable washer C is connected by arms
to a central boss, on which a powerful nut E presses after being securely tightened
up, the nut is held in place by a set screw F.
Any other suitable arrangement may be employed instead, for the same purpose.
It will be understood that the method above described of covering such cylinders
is not limited to blades with two thicknesses as described, as these may be replaced
by two separate bands wound round the drum simultaneously, one being higher
than the other. The higher one is provided internally and externally with teeth
and coustitutes the working blade, the other one, which is lower and thinner and
is not provided externally with any teeth, serves simply to maintain the required
uniform distance between the working blades.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. In a carding machine, the combination with the cylinder A. of the rigid
washer B projecting beyond the periphery of the cylinder, an adjustable washer C
adapted to fit upon the opposite end of the cylinder, a spirally wound blade wrapped
about the cylinder, and screws D adapted to draw the washer C onto the cylinder
and compress the blade.
2. In combination with plain faced cylinder A. the blade comprising a thin und
a thick portion, working teeth a in the thin portion, teeth a' in the thick portion
of the blade adapted, when the blade is applied to its cylinder, to remain open, and

page_text: dabs of solder b in the spaces between the teeth a' a'. serving to secure the blade to
the cylinder and also to secure the successive wrappings of the blade to one another.
3. In combination with the hollow cylinder A provided with heads or spiders, the
flanged washer B secured rigidly to one head, a similar washer applied to the spider
or head at the opposite end of the cylinder and flanged circumferentially to embrace
the cylinder, screws D F passing through the washer and into the head of the
cylinder, and the continuous spirally wound blade, applied to the cylinder between the
washers B. C.
