PROVISIONAL SPECIFICATION.
An Improvement in the Manufacture of Rivets.
I, GEORGE FREDERICK REDFERN, of the Firm of G. F. Redfern & Co., the
General Patent Office, No. 4, South Street, Finsbury, in the County of London,
Patent Agents, do hereby declare the nature of this invention (a communication to
me by Ebenezer Pocock, of 11 Rue de Flandre, Paris, in the Republic of France,
Manager,) to be as follows:-
This invention relates to an improvement in what are known as tubular rivets
such as are used in rivetting the sides of the heavier class of boots.
An objection to the use of this class of rivets as at present, made arises from the
fact that the rivets being made of metal have to be japanned, and this japan wears
off thereby exposing the metal.
The object of this invention is to so make the rivets that the japan is not liable
to be worn off by brushing or wear.
For this purpose I make the rivets in the usual manner, that is to say, either
split-tubular, or bifurcated, but instead of making the head flat or outwardly
convex as hitherto, I form the heads with a concave depression, whereby they are
protected from wear.
Dated the 23rd day of November 1892.

COMPLETE SPECIFICATION.
An Improvement in the Manufacture of Rivets.
I, GEORGE FREDERICK REDFERN of the Firm of G. F. Redfern & Co., the
General Patent Office, No. 4, South Street, Finsbury, in the County of London,
Patent Agents, do hereby declare the nature of this invention (a communication
to me by Ebenezer Pocock, of 11 Rue de Flandre, Paris, in the Republic of France,
Manager) 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 an improvement in what are known as tubular rivets
such as are used in rivetting the sides of the heavier class of boots.
An objection to the use of this class of rivets as at present made arises from the
fact that the rivets being made of metal have to be japanned and this japan wears
off thereby exposing the metal.
The object of this invention is to so make the rivets that the japan is not liable
to be worn off by brushing or wear.
For this purpose I make the rivets in the usual manner, that is to say, either
split-tubular, or bifurcated, but instead of making the head flat or outwardly
convex as hitherto I form the heads with a concave depression whereby they are
protected from wear.
In the accompanying drawing
Figure represents a vertical section of a tubular rivet made according to this
invention and,
Figure 2 is a section shewing two pieces of leather connected together by a
rivet similar to that shewn in Figure 1.
a is the tubular portion of the rivet and 6 is the head formed as clearly shown
with a concave depression whereby, when the rivets are in use as shewn in

page_text: Figure 2, the japan with which the rivets are coated will not be liable to be worn
off by brushing or wear as is the case when the rivet heads are made flat or
outwardly convex as has hitherto been the practice.
In the drawing I have, for the purpose of illustration, shewn my invention
applied to a plain tubular rivet but it will be obvious that my improvement is
equally applicable to other forms of rivets such as split-tubular and bifurcated
rivets.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. A tubular rivet having the head. formed with a concave depression as
herein before described.
2. The manufacture and use of the improved tubular rivets herein before described
and illustrated in the accompanying drawing.
Dated the 23rd day of August 1893.
