COMPLETE SPECIFICATION.
A New or Improved Process for Covering Various Articles with a
Coating of Celluloid or the like.
I, HENRI LAMOISSE, of 12, Rue des Saules, Paris, in the Republic of France,
Electrician, 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 application for a patent relates to a new or improved process for
covering various articles with a coating of celluloid or the like and particularly the
tubes or frames of velocipedes, and bottles or other vessels.
My invention consists in principle in surrounding the article to be covered with a
tube of celluloid, rendered very elastic, the interior diameter of which is slightly
smaller than that of the article which is to be covered in its narrowest part.
My process will be essentially understood from the following series of operations.
The tube of celluloid, which is chosen in such manner that its interior diameter is
slightly smaller than that of the article which is to be covered in its narrowest part,
and the thickness and length of which will vary according to the shape of the article
to be covered, is plunged into salt water for a certain time until it has acquired
sufficient elasticity, then into boiling water in order to render it malleable.
The tube of celluloid which can be rendered elastic and malleable in any other
convenient manner, is then expanded by any suitable means, in such manner that
the article to be covered can be introduced into the interior of the tube.
This expansion of the tube of celluloid can be effected either by the aid of
compressed air or by means of a polished copper conical rod.
In introducing for example this conical rod into the tube of celluloid its interior
diameter is progressively increased.
When the tube of celluloid thus expanded is brought to the desired dimensions the
article to be covered is introduced into the interior of this tube then the whole that
is to say the article and its covering of celluloid, is plunged into boiling water so as
to produce the contraction of the celluloid which latter in contracting energetically
closes upon the article which its covers, following its shape in all its details.
The article thus covered with a sheath or coating of celluloid is then submitted to
any suitable polishing or decorating operation.
It will be understood that I reserve to myself the employment not only of celluloid,
but all other analogous materials.
My process thus allows articles of all kinds to be covered with a sheath or coating
of celluloid or the like and I especially reserve to myself its particular application to
the tubes or frames of velocipedes, and to glass vessels.
The tubes or frames of velocipedes covered in this manner with a sheath or coating
of celluloid or the like will be protected from all oxidation and will be able to be
decorated in various ways.
Besides, glass vessels will be protected against fracture from blows by this sheath or
coating of celluloid or the like, and the latter will allow decorative effects to be
btained which may be varied to infinity.

page_text: 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 process for covering with a sheath or coating of celluloid or the like articles of
various kinds consisting in principle in surrounding the article to be covered with a
tube of celluloid or the like rendered elastic and malleable, the interior diameter of
which is slightly smaller than that of the said article in its narrowest part, and
then causing the contraction of the said tube substantially as herein described and
for the purpose stated.
2 The application of the process referred to in the preceding claim particularly to
the covering of the tubes or frames of velocipedes and glass vessels of all shapes
substantially as herein described and for the purpose stated.
Dated this 22nd day of December 1897.
