IMPROVED BOOT AND SHOE STIFFENER AND APPARATUS FOR THE MANUFACTURE THEREOF
Year: 1884

page_text: I HENRY ROYALL MINNS of .1 St Lukes Villas Maidenhead in the County
of Berks Engineer do hereby declare the nature of my invention for IMPROVED
BOOT AND SHOE STIFFENER AND APPARATUS FOR THE MANUFACTURE THEREOF
to be as follows:-
:
"
According to this Invention I form boot and Shoe stiffeners without "crimping'
which has been found necessary in order to bend and flange stiffeners as heretofore.
In order to effect the above I bend and form the flange on the stiffener in a
machine constructed substantially as follows
I fix to a suitable frame a cylinder (preferably flanged at bottom) open at both
ends in which I fit a loosely a piston capable of working a short distance and
actuated at the bottom by a spring or balance lever. The top of said piston has a
head which forms a die to form the flange and bend round the stiffener when
forced into a corresponding matrice arranged and worked as hereafter described.
The matrice is fitted into a machine similar to a drilling machine so that it may
revolve while pressing on to the aforesaid die which projects above the cylinder
and is stationary. The leather or leather board after having been stamped or cut
to the required shape is bent round the aforesaid cylinder (the edge required to be
flanged being upwards) and projecting above the same. The stiffener is held
firmly round the cylinder by means of a break band or by other suitable means
the machine is then set in action the matrice coming down and revolving at the
same time forces the leather or leather board which is to form the stiffener over
the die until this latter comes in contact with the top of the cylinder when it will
be found that the stiffener is bent round and flanged without any crimping" and
has only to be finished by moulding by any suitable means so as to fit the heel
of the last: I fit an adjustable collar on to the aforesaid piston under the said
cylinder so as to limit its action in accordance to the required depth of flange.
Dated this Nineteenth day of January 1884.

Engineer do hereby declare the nature of my said Invention for. AN IMPROVED
BOOT AND SHOE STIFFENER AND APPARATUS FOR THE MANUFACTURE THEREOF
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :―
According to this Invention I form boot and Shoe stiffeners without "crimping"
which has been found necessary in order to bend and flange stiffeners as heretofore.
In order to effect the above I bend and form the flange on the stiffeners in a
machine constructed substantially as follows:-
In the accompanying drawing Fig 1 represents vertical section of the apparatus
Fig 2 plan of same Fig 3 stiffener finished A shews the mould to be fixed on to a
machine similar to a drilling machine so that it may revolve at the same time it is
pressing down B is a ram to which is connected the counterbalance lever C.
this ram works in a cylinder D fitted or cast on on bed E. G shews an adjustable
collar fitted to the ram B so as to regulate the distance of working between the
head of ram B. and and top of the cylinder D. H represents a piece of leather
or leather board to form the stiffener placed round the cylinder D and held in
position by the band I which latter is actuated by the lever K.
The action is as follows:-
The leather or leather board being placed in position as shewn the mould A is
caused to descend and revolve at the same time as aforesaid thus pressing on the
head of the ram B and pressing it down until it comes in contact with top of
cylinder D this action will cause the leather or leather board H to be forced into
the mould A thus curving it and forming a flange of the width according to the
distance between the top of cylinder D and the under part of the head of ram B
which is adjustable as aforesaid by means of the collar G.
The stiffener when taken out assumes the appearance at Fig 3.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
-
Forming stiffeners for boots and shoes without crimping and in apparatus for
that purpose substantially as set forth..
