PROVISIONAL SPECIFICATION.
Improvements in Means or Mechanism for Cutting India-rubber and
like Substances.
I, HENRY CROFTS LONGSDON of the Firm of W. Summerscales and Sons
Limited of Keighley in the County of York, Laundry Engineers and Machine
Makers, do hereby declare the nature of this invention to be as follows :-
It relates to means or mechanism for cutting pieces of india-rubber into such
regular forms or shapes as may be required for facilitating their subsequent treat-
ment or for package or storage or other purposes and it consists of forming and
constructing these machines in such a manner that the operation may be carried
out by hand or power while the cutting knife or blade is at all times kept lubricated
to free it from the adhesive actions of the substance under operation.
In carrying my invention into effect I employ a rotary cutter or blade which I
mount in suitable framework or bearings to revolve above a table or support for
the india-rubber or like substance that has to be treated.
These bearings are made so that they may be adjusted relatively with the top of
the table as the wearing of the knife or blade, or other occasions may require,
suitable set screw and other mechanism being employed for effecting such adjustment,
while a soft metal piece (as brass) is let into the top of the table where the blade
is likely to come in contact with it in order that the cutting edge may be kept
intact or uninterfered with.
The shaft of the circular blade is arranged so that driving pulleys may be
mounted thereon if desired, while the bearings carrying this shaft are so formed
that suitable gearing wheels may be mounted thereon to be operated by a winch
or hand wheel to impart motion to said shaft when the machine is for hand
power.
Over the circular knife is arranged a guard or shield which is carried by the
adjustable bearings to which it is attached and this guard is so formed that it carries
a suitable receptacle for holding any lubricant that may be desired to be used with
the knife, this lubricant being conducted from this receptacle into contact with the
knife by felt or other wicks of absorbent material.

COMPLETE SPECIFICATION.
Improvements in Means or Mechanism for Cutting India-rubber and
like Substances.
I, HENRY CROFTS LONGSDON of the Firm of W. Summerscales and Sons
Limited of Keighley in the County of York, Laundry Engineers and Machine
Makers, 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 :-
It relates to means or mechanism for cutting pieces of india-rubber into such

page_text: regular forms or shapes as may be required for facilitating their subsequent treat-
ment or for package or storage or other purposes, and it consists of forming and
constructing these machines in such a manner that the operation may be carried
out either by hand or power while the cutting knife or blade is at all times kept
lubricated to free it from the adhesive actions of the india-rubber or other substance
being treated.
In the accompanying sheets of drawings which are illustrative of my invention :-
Figs. 1 and 2 are front and end elevations respectively of a machine made in
accordance with my invention,
Fig. 3 is a view of parts shown by Fig. 1 and as seen from above.
Figs. 4 and 5 are drawings in detail of parts hereinafter explained.
In carrying my invention into effect I employ a rotary cutter or blade a which
I mount in suitable framework or bearings 6 to revolve above a table or support c
upon and over which the india-rubber or like substance is placed and passes when
being cut by said blade a.
These bearings b are made so that they may be adjusted relatively with the top
of the top of the table c as the wearing of the blade a or as other occasion may
require, the screws d d being employed for effecting the said adjustment, while a
soft metal piece (as of brass) fis let into the table where the blade a is likely to
come in contact with it in order that the cutting-edge of said blade a may be kept
intact or uninterfered with.
The shaft g on which the blade a is fixed is arranged so that driving pulleys h h¹
may be mounted to impart motion to it through the gear wheels k k', the said
pulley being loosely mounted on the stud or support m so that when the
driving belt is on the pulley this does nothing but revolve loosely thereon while
when said belt is shifted onto the pulley h motion is imparted through the
wheels kk to the shaft g. The fly wheel p bas a handler fixed upon it so that
the machine may be manually operated whenever other power is not obtainable.
Or in place of the driving pulleys being employed the wheel k may be fixed to
the hand wheel p so that a simpler hand-power-machine only is produced.
Over the circular knife a is arranged a guaid or shields which is carried by
the adjustable bearings to which it is attached and this guard is so formed
that it carries a suitable receptacles for holding any lubricant that may be
desired to be used with the blade a, this lubricant being conducted from this
receptacles into contact with said blade a by felt or other wicks of absorbent
material which act in the well known manner.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The combination of the several parts forming a machine for cutting india-
rubber or like substances, the same being formed and arranged to operate
substantially as herein specified.
2. The combination in a machine for cutting india-rubber and like substances of
a circular blade, adjustable bearings for supporting same, and means for imparting
motion to said blade substantially as herein specified.
3. The combination in a machine for cutting india rubber and like substances of
a circular blade, adjustable bearings for supporting same, means for imparting
motion to said blade and a receptacle for supplying lubricant thereto substantially
as herein specified.
