PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus used in the Manufacture
of Boots and Shoes.
I, JOHN WILLIAM SHARP Engineer, 38 Wellington Street Kettering, Northampton-
shire do hereby declare the nature of this invention to be as follows:-
My Invention relates to improved means in machines or apparatus for forming
rands or split lifts, to a required shape for use, in the manufacture of heels for boots
& shoes.
In carrying out my invention, the machine or apparatus is constructed arranged and
operated in the following manner :-
For the purpose of forming the said rands or splits lifts, I provide a suitable frame,
to which is cast a cylindrical box or inside former. In the said inside former I employ
discs of a suitable shape; one of which is secured to the end of a shaft working in two
bearings in a line with the aforesaid inside former. At the end of the said shaft is
fitted a small spur wheel which is actuated by a pinion and fly wheel. The said discs
being arranged to revolve and slide backwards and forwards as required. The
opposite disc is secured to the end of a spindle working in a boss thrown out of line
at a suitable angle at the outer end of the aforesaid inside former. By this means a
much firmer grip is given to the material between the discs, during the forming of
the said rands or split lifts and a free delivery to the same.
The aforesaid discs are
retained in an open position by spiral or other suitable springs to admit the material
between the aforesaid discs and brought into contact by a foot lever; thus regulating
the grip on the material aforesaid.
I am aware that other well known methods and means are used for effecting this
purpose but what is new & novel in my invention is the peculiar form of the discs and
one of the said discs being thrown out of line with the other and its relative disc being
brought into contact by the application of cranks & levers or other suitable means
actuated by foot.

COMPLETE SPECIFICATION.
Improvements in Machinery or Apparatus used in the Manufacture
of Boots and Shoes.
I, JOHN WILLIAM SHARP, Engineer, 46 Wood Street Kettering Northamptonshire
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:
My Invention relates to improvements in machines or apparatus for forming rands
or split lifts to a required shape for use in the manufacture of heels for boots and
shoes.
In carrying out my Invention the machine or apparatus is constructed arranged
and operated in the following manner :-
For the purpose of forming the said rands, or split lifts I provide a suitable frame,
to which is cast a cylindrical box or inside former. In the said inside former, I
employ discs of a suitable shape, one of which is secured to the end of a shaft working
in two bearings in a line with the aforesaid inside former. At the end of the said shaft
is fitted a small spur wheel which is actuated by a pinion and fly wheel, the said disc
being arranged to revolve as required. The opposite disc is secured to the end of a
spindle, working in a boss thrown out of line, at a suitable angle at the outer end of
Price 6d.1

page_text: the aforesaid inside former; by this means a much firmer grip is given to the material
between the discs during the forming of the said rands or split lifts, and a free delivery
to the same. The aforesaid discs are normally retained in an open position by spiral
or other suitable springs to admit the material between them, but they can be brought
into contact by a foot lever, thus regulating the grip on the material aforesaid.
I am aware that other well known methods and means are used for effecting this
purpose-but what is new and novel in my invention is the peculiar forin of one of the
discs, that is to say one disc having one half of every other tooth cut away from the
centre, and its relative disc being thrown out of line at a suitable angle with the other,
and being brought into contact by the application of cranks and levers, or other
suitable means actuated by foot.
But in order to enable my improvements to be better understood I will proceed to
describe the same by reference to the accompanying drawings in which Fig. 1, Sheet 1,
represents a front elevation of my Improved Machine for the purpose of forming rands
or split lifts. Fig. 2, Sheet 1, is a broken plan of the same. Fig. 3, shews the inside
face of sliding disc and plate. Fig. 4, cylindrical box or inside former partly broken
away with inside disc and guards. Fig. 5, Sheet 2, is a front elevation of a
modification of the machine with slideing inside disc and fixed guards combined having
a stationary outside plate and disc combined with an opening to admit of the rands
or split lifts passing through. Fig. 6, represents end elevation of same.
Similar letters of reference are employed to represent similar parts.
A is the frame. B, is the hand wheel and pinion working on stud attached to
frame A. C, spur wheel. D, inside disc and shaft secured to spur wheel C. E. cylindrical
box or inside former. F, is outside plate and boss secured by means of small screws to
cylindrical box E. G, is bell crank working on pin fitted to joint in bracket H. 1, is
sliding disc slideing in boss F, the said disc 1. being fitted to joint J and actuated by bell
crank G. K, is a spring attached to bell crank G and frame A. for the purpose of
holding slideing disc I back in the position as shewn in Fig. 1. sheet 1. L, is bottom
guard. L'is top guard fitted to guard M, which is attached to cylindrical box or inside
former E. N, Fig. 4, shewing the portion cut away for the purpose of delivering the
rands or split lifts on to guard M and L¹ during operation of machine.
Fig. 5 & 6 sheet 2, is a modification of the machine as shewn on sheet 1, Fig. 1 & 2,
with a slideing and revolving disce D and guards M L and L' combined with an outside
stationary disc and plate 1 and F shewing a reversed action of the grip.
The operation of the machine is as follows, the machine is first put in motion, the
splits or rands being then placed between the two discs on to guard L. are then firmly
gripped by the operation of the cranks and levers and pass round inside the cylindrical
box or inside former to opening N. and on to guards M. and L¹.
Having now particularly described the nature of my said Invention and in what
manner the same is to be performed I would have it understood that what I claim is.
1st. The peculiar form of the cylindrical box or inside former E, substantially as
herein described and set forth in the accompanying drawings.
2nd. The combination of cylindrical box or inside former discs and guards as se
forth in the accompanying drawings & for the purpose herein described.
3rd. The combination of discs and D, as shewn in sheet 1, Fig. 2. discs 1 being
thrown out of line with disc D. as herein described and set forth in the accompanying
drawings.
4th. In combination with slideing and revolving discs, the application of bell crank
or levers for the purpose of giving a firm grip to the material during the operation o
the machine.
