IMPROVEMENTS IN THE MANUFACTURE OF BOOTS AND SHOES WITH INDIA-RUBBER SOLES
Year: 1885

page_text: MAX FRANKENBURG of 6, Lancaster Street, Leicester Manufacturer do hereby
declare the nature of my invention for IMPROVEMENTS IN THE MANUFACTURE OF
BOOTS AND SHOES WITH INDIA-RUBBER SOLES to be as follows:-
My invention relates more particularly to improvements in the manufacture of
Lawn-tennis and other boots and shoes to which india-rubber soles are secured, the
object of my improvements being to fasten the india-rubber inore securely to the
leather sole, thereby increasing the durability of the boots or shoes at the same
time improving their appearance and lessening the cost of manufacture.
Hitherto the india-rubber soles have been fastened to the leather soles by the
use of metal fastenings at the edges of the india-rubber and the welt of the leather
soles, which caused a defect in the appearance by squeezing out the edges of the
india-rubber and the metal fastenings were liable to break through the edges,
therefore the india-rubber soles come loose from the leather soles.
By my invention I secure the india-rubber soles to the leather soles by a solution
of india-rubber or cement in the usual manner and further secure with pins made
with heads of compressed leather of any desired shape pattern and colour, I use for
driving these pins through the rubber and leather soles a metal stamp formed to
fit the exact shape of the leather head. During this process the shoe is kept on a
last against which the pins clinch inside, the leather heads preventing the rubber
from being cut through as is the case when metal heads are used in direct con-
junction with the rubber.
The use, as above described which I claim to have invented of leather heads in
securing the rubber to the leather sole has the following advantages.
It causes the leather and rubber soles to adhere perfectly, it prevents the dis-
fugerment caused by squeezing out the edges of the soles, it can be made to keep
the pattern of the rubber sole unaltered and if desired to ornament it.

I MAX FRANKENBURG of 6 Lancaster Street, Leicester in the County of
Leicestershire, India rubber Manufacturer do hereby declare the nature of this
invention for IMPROVEMENTS IN THE MANUFACTURE OF BOOTS AND SHOES WITH
INDIA RUBBER SOLES 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 the manufacture of boots or shoes with India rubber
soles such as are used by Lawn Tennis players and others and the objects of my
improvements are to fasten the India rubber soles more securely to the leather soles
or foundation than has hitherto been done (thereby increasing the durability of the
boots or shoes); to improve the appearance of the boots or shoes; and to lessen
the cost of their manufacture.
"'
"According to my Invention having firstly attached the India rubber sole to the
leather sole or foundation by a solution of India rubber or cement in the usual
manner I then firmly secure the said india rubber sole to the said leather sole or
foundation by means of pins or rivets or other like made with heads of leather
preferably of compressed leather and of any desired shape and colour.
To facilitate the driving of these studs through the rubber and leather soles a
metal stamp formed to fit the leather head may be used and during this process
the shoe or boot is held upon a metal last against which the pins rivets or the like
are clinched on the inside of the sole or foundation. To ensure the firm fastening
of the pins rivets or the like in their place I prefer to split their point ends so
that when they are forced against the last they splay out and are thereby firmly
secured in place. The leather heads improve the appearance and prevent the
rubber from being cut through as frequently occurs when metal heads are used in
direct contact with the rubber.
Where the rubber soles are formed with a groved surface forming a number of
studs or projections I prefer to make the leather beads of the pins or rivets or the
like of the shape of one of these studs or projections and to form the sole without
a stud or projection at the places where the pins or rivets or the like are to be
inserted or to remove the rubber studs or projections at these places the leather
heads of the pins or the rivets or the like taking the places of the said rubber
studs or projections and forming a similar surface all over the sole but I do not
limit myself to this as for example when a plain rubber sole is made it may be
formed with recesses at the places where the pins rivets or the like are to be
inserted and in these ricesses the leather heads of the pins or the like will lie.
I am aware that it has been proposed to fasten India rubber soles to leather
soles by the use of metal fastenings rivetted through the edges of the India rubber
and leather soles and pinched, and therefore I make no claim to the use of such
metal fastenings which by squeezing out the edges of the India rubber give an
unsightly appearance to the boot or shoe and the said metal fastenings are liable to
break through the edges so that the India rubber soles become loosened from the
leather soles,

page_text: . 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
1. In the manufacture of boots or shoes with India rubber soles the fastening-of
the rubber sole to the foundation or leather sole by means of pins or rivets or the
like having heads of leather substantially as herein before described.
2. In the manufacture of boots or shoes with India rubber soles with studs or
projections on their surface the fastening of the rubber sole to the foundation or
leather sole by means of leather headed pins or rivets or the like the heads of
which to be the place of some of the rubber studs or projections substantially as
hereinbefore described.
