PROVISIONAL SPECIFICATION.
Improvements in Certain Ironing or Calendering Machines for
Laundry Purposes.
I, JOSEPH WEST AKAM, of 5, The Châlets, Undercliffe, Bradford, in the County of
York, Laundry Manager, do hereby declare the nature of this invention to be as
follows:-
66
This invention relates to improvements in that class of ironing or calendering
machine for laundry purposes commonly known as the Crabtree ironer" and its
object is to prevent lumps of felt from the endless blanket and dirt adhering to and
accumulating on the lower or inner guide and pressure rollers.
To carry out my improvements I positively drive the lower or inner guide or
pressure rollers as well as and at the same speed as the upper ones. Consequently
when the blanket stopped or retarded by the act of turning up the heated bed such
rollers, instead of stopping as well continue to revolve therefore their peripheries rub
against the inner face of the blanket and anything adhering to such peripheries is
thereby cleaned off.
These lower rollers may be driven by a chain and sprocket wheels from the upper
rollers, or in any other convenient way.
The bottom tension roller may be driven in a similar way but this is not so
important as projections on this roller do not materially effect the pressure of the
blanket upon the articles being calendered.
Dated this 28th day of February 1898.

Improvements in Certain Ironing or Calendering Machines for
Laundry Purposes.
I, JOSEPH WEST AKAM, of 5, The Chalets, Undercliffe, Bradford, in the County of
York, Laundry Manager, 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 to improvements in that class of ironing or calendering
machine for laundry purposes commonly known as the "Crabtree ironer" and
particularly to that somewhat modified form of ironer in which the blanket passes
beneath the heated bed and then down under a tension roller beneath, and its object
is to prevent lumps of felt from the endless blanket and dirt adhering to and
accumulating on the lower or inner guide and pressure rollers.

To fully describe my improvements reference is made to the accompanying
drawing which represents an end view of such parts of a "Crabtree ironer as are
necessary to illustrate the application of my improvements thereto.
To carry out my improvements I positively drive the lower or inner guide or
pressure rollers A, A as well as and at the same speed as the upper ones B, B.
Consequently when the blanket is stopped or retarded by the act of turning up the
heated bed such rollers, instead of stopping as well continues to revolve therefore
their peripheries rub against the inner face of the blanket C and anything adhering
to such peripheries is thereby cleaned off.
These lower rollers may be driven by a chain D and sprocket wheels E, E, E from
one of the upper rollers, or in any other convenient way.
The bottom tension roller F may be driven in a similar way but this is not so
important as projections on this roller do not materially effect the pressure of the
blanket upon the articles being calendered.
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
In an ironing machine of the type specified, positively driving the lower or inner
rollers for the purpose specified.
