Improvements in Rivets or Fastenings applicable to Boots and
Shoes, and for other purposes.
We ETIENNE MONDAIN, Shoemaker of 75 Rue Sedaine and EDMOND JULIEN
PRINCET, Baker of 32 Rue St. Severin both of Paris in the Republic of France
do hereby declare the nature of this invention to be as follows:-
The present improvements relate to rivets or fastenings of general application
having the advantage of being invisible when applied. They are applicable to
boots and shoes, to bands or belts for machinery, to saddlery, harness making and
other uses.
When used in the attachment of the soles of boots and shoes our rivets afford
great advantages over other known systems.
They replace with advantage hand sewing to which they are superior in firmness
and as to economy of hand work. They are also infinitely superior to machine
sewing their solidity withstanding any usual test whilst machine sewing leaves so
much to be desired that it is not practicable for the sewing of men's boots. They
are likewise cheaper in net cost.
Our rivet obviates the inconvenience of being obliged to withdraw the last before
the finish of the boot an operation rendered unnecessary by its use as well as that
of opening and closing the channel.
By these means we obtain a saving over hand work of nearly one third whilst
producing much better finished work.
Compared with methods of nailed and screwed shoes the use of our rivet permits
of some economy being realised over hand work and is much more solid even when
employed with inferior qualities of leather. Indeed, to obtain solidity with nail
and screw methods it becomes necessary to employ inner soles of stronger and
better quality consequently dearer. Whereas by our rivetting a much greater
solidity is obtained, we can yet employ much inferior material.
The form of the rivet may take that of a six-pointed star-three shorter points-
three longer ones-in application the three longer points may be bent and gathered
in a sort of matrix in one direction and the three shorter points in the opposite
direction. The three shorter points may be held in a pressing tool conformably
shaped and the longer points forced or pressed into the substance of the inner or
first sole.
The outer sole may be fixed on the then projecting shorter points, or the
rivets may in the one direction have a number of points and in the other
direction a barbed head, or the rivet may consist of opposed points with a
flanged centre.
The number of points in any case may be varied.
The rivets may be of sheet iron galvanised, copper, or other suitable material.
When applied, the plate or base connecting the two sets of points or projections of
the rivet lying between the soles prevents them from entering too far into the
substance of either.
Similar procedure will be followed in applying the rivets in the manufacture of
saddlery, harness and other goods.

Improvements in Rivets or Fastenings applicable to Boots and
Shoes, and for other purposes.
We ETIENNE MONDAIN, Shoemaker, of 75 Rue Sedaine, and EDMOND JULIEN
PRINCET, Baker, of 32 Rue St. Severin, both of Paris in the Republic of France
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:-
The present improvements relate to rivets or fastenings of general application
having the advantage of being invisible when applied. They are applicable to
boots and shoes, to bands or belts for machinery, to saddlery, harness making and
other uses.
When used in the attachment of the soles of boots and shoes, our rivets afford
great advantages over other known systems.
They replace with advantage hand sewing to which they are superior in
firmness and as to economy of hand work. They are also infinitely superior to
machine sewing their solidity withstanding any usual test whilst machine sewing
leaves so much to be desired that it is not practicable for the sewing of mens
boots. They are likewise cheaper in net cost.
Our rivet obviates the inconvenience of being obliged to withdraw the last before
the finish of the boot an operation rendered unnecessary by its use as well as that
of opening and closing the channel.
By these means we obtain a saving over hand work of nearly one third whilst
producing much better finished work.
Compared with methods of nailed and screwed shoes the use of our rivet permits
of some-economy being realized over hand work and is much more solid even when
employed with inferior qualities of leather.
Indeed to obtain solidity with nail and screw methods it becomes necessary to
employ inner soles of stronger and better quality consequently dearer, whereas, by
our rivetting a much greater solidity is obtained, we can yet employ much inferior
material.
The form of the rivet may take that of a six pointed star-three shorter points-
three longer ones-in application the three longer points may be bent and
gathered in a sort of matrix in one direction and the three shorter points in the
opposite direction. The three shorter points may be held in a pressing tool
conformably shaped and the longer points forced or pressed into the substance of
the inner or first sole.
The outer sole may be fixed on the then projecting shorter points, or the rivets
may in the one direction have a number of points and in the other direction a barbed
head, or the rivet 'may consist of oppositely directed points having a common flanged
base or centre.
The number of points in any case may be varied projecting oppositely from a flat
central portion.
The rivets may be of sheet iron galvanised, copper, or other suitable material.
When applied the plate or base connecting the two sets of points or projections of
the rivet lying between the soles prevents them from entering too far into the
substance of either.
Similar procedure will be followed in applying the rivets in the manufacture of
saddlery, harness and other goods.

page_text: downward in a small holder the rivet is obtained as shewn by side view in
Figure 2.
Figure 3 represents two modifications of form or variety of our rivet.
Figure 4 shews a tool adapted to drive the rivets into the first sole.
Figure 5 shews the mode of fixing the rivets in the first sole, and
Figure 6 shows the mode of fixing these rivets in the second sole and consequently
the whole operation.
It will thus be seen by Figure 2 that the rivet is formed of two series of points
say 3, 4 or other number to each series these points being secured to their base
by an intermediate flat part about the middle or nearly so of the rivet.
The rivets may be of sheet iron galvanized, copper or other suitable material.
The rivet driven first into the first sole (Figure 5) while held in the tool
(Figure 4) leaves the other points projecting. This tool is shewn as a cylinder
with one end having holes corresponding in number with the number of fangs of the
rivet in the one direction.
These points held in these holes serve in pressing the oppositely projecting fangs
against the first sole then by a blow on the opposite end of the tool-say by a
hammer or otherwise, these points of the rivet are driven into the sole A and caused
to diverge so as to lock themselves into the thickness of the upper and unite the
various parts forming the upper sole.
The intermediate base plate rests against the outer surface thus preventing the
points from penetrating too far into the shoe, the opposite points being left free and
projecting nearly perpendicularly from the face of the sole.
In preparing the rivet for use its points are slightly diverged to facilitate
spreading in penetrating the soles and clinching into the superposed thicknesses to
secure sufficient resistance.
The first operation effected the second sole is applied upon the projecting points
of the rivets and the outer sole being hammered or driven thereupon the like effect is
produced as in the case of the first sole and the second set of points likewise become
diverged and clinched in the second sole.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1: A rivet or fastening invisible when applied composed of a flat central part
on each side of which are arranged points in suitable number, slightly diverging
from one another, for the purpose of obtaining by clinching the junction of two
pieces of leather or other material, substantially as that hereinbefore described in
respect of Figures 1, 2, and 3 of the accompanying drawing.
2: The application of the herein before described rivet for uniting the soles of
shoes, a series of points being first driven into the first sole by means of a point
driving tool-say, such as shewn in Figure 4 or other suitable tool-then the other
series of points being driven into the sole properly so called by the application of
this last sole upon the free points, or inversely, substantially as herein before
described in respect of Figures 4, 5 and 6 of the accompanying drawing.
3-The application of our rivet in saddlery, harness making and generally in
all industries wherein it may be usefully employed.
4-The method of construction and application of rivets or fastenings to boots
and shoes and for other purposes as set forth.
