Improvements in the Production of Bowls Used in Mangles and
other Apparatus.
I JOHN OLIVER carrying on business under the style of David Bentley of Greengate
Salford in the County of Lancaster, Bowl Manufacturer, do hereby declare the nature
of this invention to be as follows
My Invention relates to the bowls used in mangles and in other machinery and
particularly to the cases wherein such bowls are made of wood. It is well known tha
the ordinary wooden bowls are liable to deterioration especially when exposed to
moisture and in any case are liable to split and to become uneven in form. The
object of my invention is to produce a bowl which whilst being made of wood or of a
woody substance will be more durable and less liable to changes in form than the
ordinary bowl. For the purpose of my invention I use a woody fibre obtained by
reducing wood to a filamentous condition so that to some extent it resembles hemp or
tow. This material I form into bowls by compression in a similar manner as when
operating in the production of cotton bowls. In practice I should prefer to compress
the material into rings and thread a number of these rings on to a shaft and complete
the formation by pressing the rings together with inore or less force according to the
degree of hardness which the bowl is to possess. The bowl is then finished by being
turned to the required form and diameter as in the finishing of ordinary bowls.

page_text: I JOHN OLIVER carrying on business under the style of David Bentley of Greengate
Salford in the County of Lancaster, Bowl Manufacturer 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 that is to say :-
My Invention relates to the bowls used in mangles and in other machinery and
particularly to the cases wherein such bowls are made of wood. It is well known
that the ordinary wooden bowls are liable to deterioration especially when exposed to
moisture or heat or to great variations in temperature or hygrometric conditions and
in every case are liable to crack or split and to become uneven in form. It is usual
to cut out any knots which may be in the roller or in the partly formed roller and
to fill the cavities thereby formed with pieces of wood. In the ordinary use of the
bowl the cracks in the periphery and the nicks at the joinings of the pieces let in
with the general body of the roller in many cases leave marks or impressions upon
the woven fabric which is being operated upon whereby an imperfect result is
obtained and greater care is required in the subsequent processes in order to produce
the required smoothness or evenness of finish. The object of my invention is to
produce a bowl which whilst being made of wood or of a woody substance will be
more durable and less liable to changes in form than the ordinary bowl and will be
otherwise free from the indicated defects. For the purpose of my invention I use a
woody fibre obtained by reducing wood to a filamentous condition so that to some
extent it resembles hemp or tow. This material I form into bowls by compression in
a similar manner as when operating in the production of cotton bowls. In practice 1
should prefer to compress the material into rings and thread a number of these rings
on to a shaft and complete the formation by pressing the rings together with more or
less force according to the degree of hardness which the bowl is to possess. The
bowl is then finished by being turned to the required form and diameter as in the
finishing of ordinary bowls. I have found as the result of experimental working that
the best result is obtained when the wood is most finely divided so as to resemble
coarse hair, hemp or tow as aforesaid but I do not confine myself to the use of such
exceedingly fine filamentous wood as a suitably good result might be obtained by
using wood in the condition of thin narrow shavings but I should prefer that the
width of such shavings should not exceed one quarter of an inch. I am aware that
bowls have been made to some extent of ordinary coarse shavings such as are produced
in carpenters shops in the ordinary way of business or of such shavings as result from
the ordinary action of wood planing machinery but such bowls have not possessed the
uniformity of density of my improved bowls and have not even replaced with

page_text: advantage the ordinary wooden bowl. I therefore lay no claim excepting to the
bowls when made of the more suitable material herein described.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is :-
(1) The bowl made from fine filamentous wood compressed in a similar manner as
when making ordinary cotton bowls substantially as set forth and indicated.
(2) The production of wood bowls by compressing wood reduced to a filamentous
condition or to the condition of fine narrow shavings which will compact well together
substantially as fet forth and indicated.
