ROVED ROLLERS FOR WRINGING AND MANGLING MACHINES
Year: 1884

page_text: I ROBERT LONGDON of Wards Buildings Deansgate Manchester in the County of
Lancaster Insurance Agent do hereby declare the nature of my invention for
IMPROVED ROLLERS FOR WRINGING AND MANGLING MACHINES" to be as follows:-
The object of this invention is to manufacture rollers for wringing and mangling
machines from a material which shall be more economical in cost and more durable
than wood and not subject to deterioration by either long continued moisture or
pressure.
The material which I propose to employ for this purpose is slate; and in
carrying out my invention I take a block of slate of the required thickness and
length and I drill a round hole through the same larger in diameter than tho
spindle or axle on which it is to be fixed. The iron spindle or axle may be either
round or square and is fixed therein with Portland Cament or other suitable
composition.
The roller having been roughed out (either before or after fixing the spindle) to
about the form and size required, it is placed in a lathe and turned and polished
to a true cylindrical form.
Or, I make the roller in two halves, planing each portion in a planing machino
to a semi-cylindrical form externally, and at the same time I plane a semi-cylin-
drical or angular groove in the inside from end to end. The iron spindle which
may be either square or round in section is cemented in as before and the two
halves of the slate roller are united by metal clamps or by cement, or by both
clamping and cement, or in any other convenient manner.

page_text: I ROBERT LONGDON of Wards Buildings Deansgate Manchester in the County of
Lancaster Insurance Agent do hereby declare the naturo of my invention for
"IMPROVED ROLLERS FOR WRINGING AND MANGLING MACHINES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
The object of this invention is to manufacture rollers for wringing and mangling
or calendering machines from a material which shall be more economical because
inore durable than wood and not subject to deterioration by either long continued
moisture or pressure.
The material which I propose to employ for this purpose is slate and the manner
in which I construct my improved rollers from this material will be readily under-
stood upon reference to the annexed drawing and the following explanation
thereof.
In carrying out my invention I take a block of slate of the required thickness
and length and I drill a round holo longitudinally through the same from end to
end, and larger in diameter than the spindle or axle on which it is to be fixed.
The iron spindle or axle may be either round or square and either solid or
tubular and is fixed therein with Portland cement or other suitable composition.
The roller a, a see Figs 1 and 2. having been roughed out (either before or after
fixing on the spindle b, b) to about the form and size required it is placed in a
lathe and its ends having been reduced in diameter are fitted with rings of brass
or other suitable metal c, c to prevent splitting of the slate and the roller is then
turned polished and finished to a true cylindrical form.
Instead of making the rollers of one solid piece of slate I sometimes make
them in two halves a', al as shown at Fig. 3. planing each portion in a planing
machine to a semi-cylindrical form externally, and at the same time I plano a
semi-cylindrical or angular groove d in the inside from end to end. The iron
spindle b, bis cemented in as before and the two halves a', al of the slate roller
are united by metal clamps or rings c, c as shown at Fig. 4. or by cement, or by
both clamping and cement, or in any other convenient manner.
I. find however by experience that in order to reduce the strain upon the slate
it is preferable to connect the latter to the axle b, b by means of a cast iron boss e, c
at each end as shown at Figs 5 and 6, the said bosses having driving pins or
pegs ff cast upon their inner faces and taking into holes drilled in the ends of the
slate rollers a, a. The bosses e, e are fixed to the axles b, b by means of pins g, g or
otherwise.

page_text: Having now particularly described and ascertained the nature and object of my
said invention and in what manner the same is to be performed I declare that
what I claim is
The manufacture of improved rollers for wringing and mangling or calendering
machines from slate substantially in the manner hereinbefore described and
illustrated by the drawings annexed.
