WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake and Co, Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN AND RELATING TO CYLINDERS
FOR PICKING OR BURRING MACHINES [a communication to him from abroad
by Frederick G Sargent and Allan C Sargent both of Graniteville, Massachusetts
United States of America]
This invention relates to cylinders for picking and burring machines for opening
wool and other fibrous substances, and it consists partly in uniting the strips of
metal, upon which the teeth of the cylinder are formed, to each other and to the
metallic surface of the cylinder, and it further partly consists in the method or
process of accomplishing this result, all substantially as hereinafter described.
According to the said invention the picker cylinder is composed of a central
body of wood or other suitable material which is covered by a metallic sheet. A
metallic cap covers the end of the cylinder.
The teeth are cut from a strip of metal which is wound spirally around the
cylinder, with, the successive layers or coils adjacent to each other to form a
continuous toothed surface for the cylinder when completed. Sometimes the strip
of metal having the teeth cut thereon is shouldered on one side to form a space
between the successive rows of teeth, and sometimes thin strips of metal are
inserted between the successive coils of the toothed strip to form this space
between the teeth on the finished cylinder. Grooves are made in the sides of the
toothed strip into which wires are inserted to hold the coils of the said strip in
place.

page_text: The metal sheet surrounding the cylinder is covered with solder or tin which
can be readily fused, and the toothed strip is also covered with solder or tin before
applying it to the cylinder.
The said cylinder is then suspended by its end bearings in any suitable supports
which will enable it to be easily revolved. A gas-pipe curved to conform to the
circumference of the cylinder and having small holes for lighted jets of gas is then
mounted on an arm in such relation to the cylinder that, as the strip of metal is
wound upon the cylinder as it is slowly revolved, the lighted jets of gas will
impinge against the same. This causes the solder or tin upon the said strip and
the metal sheet to be continuously and progressively melted and fused together,
and the successive coils of the metal strip to be soldered to those previously wound
upon the cylinder, as the rotation of the same is continued. The surface of the
cylinder when thus formed is similarly provided with teeth on all parts. The
arm carrying the gas-pipe is so arranged that the said pipe can be shifted along
the surface of the cylinder as the coils are required to be subjected to the heat
while being successively wound. upon it, or the cylinder may be mounted in
shifting bearings so as to move it past the pipe and accomplish the same result.
By this process we effect the soldering in an economical and expeditious
manner

WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, London " IMPROVEMENTS IN AND RELATING TO CYLINDERS
FOR PICKING OR BURRING MACHINES A communication to me from abroad
by Frederick G. Sargent and Allan C. Sargent, both of Graniteville, Massachusetts,
United States of America
This invention relates to cylinders for picking and burring machines for
opening wool and other fibrous substances, and it consists partly in uniting the
strips of metal, upon which the teeth of the cylinder are formed, to each other.
and to the metallic surface of the cylinder so that they shall form a homogeneous
surface when the cylinder is completed; and it further partly consists in the
method or process of accomplishing this result, all substantially as hereinafter
described.
In the accompanying drawing.
Figure 1 represents a picker cylinder in process of having teeth applied to it.
according to this invention
Figure 2 is a section of a portion of the cylinder when completed
Figure 3 is a view of a portion of the same drawn to an enlarged scale
Figure 4 is an end elevation of the cylinder and soldering pipe fixed in their
supporting stand
Figure 5 is a front elevation of the same
A indicates the picker cylinder composed of a central body B of wood or other
suitable material which on its cylindrical surface is covered by the metallic sheet a.
A metallic cap C covers the end of the cylinder.
D indicates the strip or strips of metal in which the teeth are cut, which strip
or strips is or are wound spirally around the cylinder, with the successive layers
or convolutions adjacent to each other, to form a continuous toothed surface for
the cylinder when completed.
Sometimes the strip of metal having the teeth cut thereon is shouldered on one
side to form a space between the successive rows of teeth and sometimes thin
strips of metal d are inserted between the successive coils of the toothed strip to
form this space between the teeth on the finished cylinder. Grooves are made
in the sides of the toothed strip D into which wires c are inserted to hold the
coils of the strip in place as shown. These methods of fastening the toothed
strip upon the cylinder are well known and require no further description to be
readily understood.
The metal sheet a surrounding the cylinder is covered with solder or tin which
can be readily fused, and the toothed strip D is also covered with solder or tin
before applying it to the cylinder.
The said cylinder is then suspended by its journals in any suitable supports
which will enable it to be easily revolved.
A gas pipe E curved to conform to the periphery of the cylinder and having
small holes for lighted jets of gas e¹ is then mounted on an arm e¹¹ in such
relation to the cylinder that as the strip D is wound upon the cylinder as it is
slowly revolved the lighted jets of gas will impinge against the same. This
causes the solder or tin upon the strip D and the metal sheet a to be continuously
and progressively melted and fused together, and the successive coils of the
strip D to be soldered to those previously wound upon the cylinder, as the rotation
of the same is continued

page_text: The surface of the cylinder when thus formed is similarly provided with teeth
on all parts and possesses great strength and durability.
The arm ell is so arranged that the gas pipe E can be shifted along the surface
of the cylinder as the coils are required to be subjected to the heat while being
successively wound upon it; or the cylinder may be mounted in shifting bearings
so as to move it endway's past the pipe E and accomplish the same result.
S indicates a screw threaded shaft revolved by the pulleys and carrying upon
it the nut s¹ attached to the pipe E for moving the same longitudinally along the
surface of the cylinder as the soldering process is being performed.
R is the stand which supports the machine
By this process the soldering is accomplished in an economical and expeditious
manner
Having thus fully described the said invention as communicated to me by my
foreign correspondents and the manner of performing the same I wish it understood
that I claim
First. The toothed picker cylinder A having its successive coils or convolutions
of toothed metal- cemented or soldered together, and to its metal covering a,
substantially as described.
Second The process of soldering or uniting the toothed strip D to the adjacent
metal as it is wound upon the cylinder in successive coils, substantially as described.
Third In combination with the successive coils of the toothed strip D forming
the cylinder surface, the intervening holding wires c, the whole being soldered or
cemented together, substantially as described.
In witness whereof I the said William Robert Lake have hereunto set my hand
and seal this third day of January in the year of our Lord one thousand eight
hundred and eighty four..
