page_text: 1, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature of
this invention to be as follows:-
This invention relates especially to the construction of wheels or rollers employed in
machines for arranging jute and other fibres parallel or nearly parallel to each other
for forming them into a species of ribbon or sliver preparatory to spinning.
Heretofore these wheels or rollers when made of wood have been cut or turned upon
a lathe without reference to the lay or position of the fibre or grain of the wood.
When so made the said wheels or rollers will weather check and split and in use their
edges will soon become ragged and chip or split off in such a manner as to render
them worthless and require the substitution of new wheels or rollers at a considerable
expense.
The objects of this invention are to so construct the wheels or rollers of carding or
slivering machines as to enable them to work without becoming ragged or chipped
and to wear for a much greater period of time than heretofore.
To attain these ends the said invention consists essentially in making the said
wheels or rollers in segments and in cutting or sawing the wood of which the said
segments are composed in such a manner that when the said segments are united the
fibre or grain of the wood will be presented endwise to the frictional surface to which
the wheels or rollers are opposed. By such construction the edges of the said wheels
or rollers will wear equally and not become broken or chipped by contact with the
fluted shaft of the slivering machine. In carrying out my invention I employ timber
of suitable dimensions having as straight and parallel grain, or fibre as can readily be
obtained. From this wood I cut a number of tapering sections the grain of which
runs lengthwise of the section and I unite a suitable number of the said sections to
form a wheel or disc.

page_text: In practice a sufficient number of these segmental sections are dipped into glue
and placed flatwise within a circular form or mould of ordinary construction, the
latter being adapted to be expanded or contracted by screws and when screwed up to
cause all the sections to be united and compressed edgewise together to form the disc.
The inner ends of these sections are held firmly between metal or other discs forming
a hub.
A central annular depression may be made in the compression mould or
former of sufficient dimensions to receive one disc. When the wheel or roller is
formed the other disc is placed over the centre of the united sections and the two
discs are nailed through and through by clout nails or are connected by screws
which also pass through the tapering sections composing the wheel or roller.
The sections composing the wheel or roller are thus all compressed together and
united centrally by the centre discs and glue.
When the glue or other adhesive material employed is sufficiently set the wheel is
removed from the former or mould and placed in a lathe and bored centrally and the
periphery turned off smoothly so that no ragged edges is presented to the jute or
other fibre to be slivered.
In the above description I have set forth the best method which I have discovered
for constructing the said wheels or rollers but it is evident that other shapes or
sections of wooden strips may be employed to form wheels or rollers of this character,
cut lengthwise with the grain or fibre of the wood, and so arranged so as to
present the grain or fibre endwise to the frictional bearing surface to which the wheel
is opposed.

Improvements relating to Means for Forming Slivers of Jute and
other Fibres.
I. HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 especially to the construction of wheels or rollers employed in
machines for arranging jute and other fibres parallel or nearly parallel to each other
for forming them into a species of ribbon or sliver preparatory to spinning.
Heretofore these wheels or rollers when made of wood have been cut or turned
upon a lathe without reference to the lay or position of the fibre or grain of the wood.
When so made the said wheels or rollers will weather check and split and in use their
edges will soon become ragged and chip or split off in such a manner as to render
them worthless and require the substitution of new wheels or rollers at a considerable
expense.
The objects of this invention are to so construct the wheels or rollers of carding or
slivering machines as to enable them to work without becoming ragged or chipped;
and to wear for a much greater period of time than heretofore.
To attain these ends the said invention consists essentially in making the said
wheels or rollers in segments and in cutting or sawing the wood of which the said
segments are composed in such a manner that when the said segments are united the
fibre or grain of the wood will be presented end wise to the frictional surface to which
the wheels or rollers are opposed. By such construction the edges of the said wheels
or rollers will wear equally and not become broken or chipped by contact with the
fluted shaft of the slivering machine.
In the accompanying drawings,
Figure 1 is a plan view of my improved wheel or roller for slivering jute.
Figure 2 is a cross section through the centre of the wheel.
Similar letters of reference indicate corresponding parts in both figures.
In carrying out my invention I employ timber of suitable dimensions having as
straight and parallel grain or fibre as can readily be obtained. From this wood 1
cut a number of tapering sections A, A, the grain of which runs lengthwise of the
sections, and I unite a suitable number of the said sections to form a wheel or disc B,
as shown in Figure 1.
In practice a sufficient number of these segmental sections are dipped into glue and
placed flatwise within a circular form or mould of ordinary construction, the latter
being adapted to be expanded or contracted by screws and when screwed up to cause
all the sections to be united and compressed edgewise together forming the disc B.
The inner ends of these sections are held firmly between metal or other discs C, C*,
forming à hub. A central annular depression may be made in the compression mould

page_text: or former of sufficient dimensions to receive the disc C, and when the wheel or roller
is formed the other disc C✶ is placed over the centre of the united sections and the
two discs are nailed through and through by clout nails or are connected by screws
which also pass through the tapering sections composing the wheel or roller. The
sections composing the wheel or roller are thus all compressed together and united
centrally by the centre discs and glue.
When the glue or other adhesive material employed is sufficiently set the wheel is
removed from the former or mould and placed in a lathe and bored centrally and the
periphering turned off smoothly so that no ragged edge is presented to the jute or
other fibre to be slivered.
In the above description I have set forth the best method which I have discovered
for constructing the said wheels or rollers but it is evident that other shapes or
sections of wooden strips may be employed to form wheels or rollers of this character,
cut lengthwise with the grain or fibre of the wood, and so arranged as to present
the grain or fibre endwise to the frictional bearing surface to which the wheel is
opposed and hence I do not confine myself strictly to this particular form of
construction of the parts.
Having now particularly described and ascertained the nature of the said invention,
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 :-
First. The herein described method of constructing wheels or rollers for machines,
for slivering jute and other fibres, which consists in cutting the timber or wood, of
which the said wheels or rollers are composed into sections longitudinally with the
grain and uniting the sections so that the grain or fibre of the wood will be presented
end wise to the frictional surfaces to which the wheel or roller is opposed.
Second. The method herein described of constructing wheels or rollers for slivering
machines which consists in cutting the wood or lumber of which they are composed
into segments or sections lengthwise with the fibre or grain and arranging these
sections or segments around the axis of revolution so that when the wheel is turned
into proper form for operation the fibre or grain of the edge thereof will be presented
end wise to the frictional surfaces to which it is opposed.
