Improvements relating to the Covering of Various Articles with
Xylonite or Celluloid.
I, ERNEST ADOLPHUS BLUEMEL, of the Firm of C. W. Bluemel & Brothers, of
17 Alfred Street, Bow, in the County of Middlesex, Manufacturer, do hereby declare
the nature of this invention to be as follows: :-
The present method of covering or making articles with xylonite or celluloid &c.
consists in moulding, pressing, or similarly preparing xylonite or celluloid to the
desired shape and in two parts. These are placed in the mould with or without the
article to be covered and are secured by heat etc. so as to cause them to adhere to
each other. In some cases this method is objectionable by reason of the seams
produced where the two parts are joined, besides requiring special moulds, presses,
or the like, for each article of a different size or shape, and is necessarily a tedious
and costly process. Now according to this invention I cover or make fancy shapes in
wood, papier maché, metal and the like with xylonite or celluloid in a
simple manner and without the aid of any kind of mould, press, die, or the like, and
cheap and
without the seams already referred to.
To cover an article I select a piece of xylonite or celluloid tubing of the requisite
length and smaller in diameter than the article to be covered. This tube-I immerse
in hot water or steam to soften and stretch it to the required size by gently pulling it
over a taper mandrill of a suitable size, then immerse the whole in cold water, with-
draw the mandrill and place the tube on the article to be covered then immerse the
whole in hot water again and leave it there until the heat has caused the xylonite or
celluloid: to contract, and fit closely on to the article within the stretched tube, then
cool in cold water, and if necessary, plug up the end or ends of the tube with
xylonite or celluloid of similar grain etc.

Improvements relating to the Covering of Various Articles with
Xylonite or Celluloid.
I, ERNEST ADOLPHUS BLUEMEL, of the Firm of C. W. Bluemel & Brothers, of
17 Alfred Street, Bow, in the County of Middlesex, Manufacturer, 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 method of covering or making articles with xylonite or celluloid etc.
consists in moulding, pressing, or similarly preparing xylonite or celluloid to the
desired shape and in two parts. These are placed in the mould with or without the
article to be covered and are secured by heat etc. so as to cause them to adhere to
each other. In some cases this method is objectionable by reason of the seams pro-
duced where the two parts are joined, besides requiring special moulds, presses, or
the like, for each article of a different size or shape, and is necessarily a tedious and
costly process. Now according to this invention I cover or make fancy shapes in
wood, papier maché, metal and the like with xylonite or celluloid in a cheap and
simple manner and without the aid of any kind of mould, press, die or the like, and
without the seams already referred to.

page_text: To cover an article I select a piece of xylonite or celluloid tubing smaller in
diameter and longer than the article to be covered in proportion to the length and size
of same. I then heat a taper mandrel of a suitable size by placing it in boiling water
or steam, or other heating medium at about the same temperature, i.e. 1000 C. I then
place the selected xylonite or celluloid tube in the boiling water or steam etc. and allow
it to remain there for about 30 seconds or so. After the mandrel has been subjected
to heat for about 30 seconds I withdraw it, wipe it dry and rub a little oil or grease.
on the same. I also take out the xylonite or celluloid tube when sufficiently heated
and commence to gently stretch it over the heated mandrel, should it not stretch to
the size required the first time, I immerse the whole in the boiling water or steam etc.
again for about 20 seconds, and then stretch it. I repeat this process until the tube is
stretched to the size required. This being effected, I immerse the whole in cold water
for about one or two seconds, withdraw the mandrel quickly from the tube and allow
the tube to cool in the water. When the tube is cool I take the article to be covered,
place it inside the stretched tube and immerse the whole in boiling water or steam etc.
for about 30 seconds or a little longer if necessary, until the tube has contracted and
fits closely on to the article within the stretched tube, when I take the then covered
article out and cool it in cold water again; and close or plug up the end or ends if
necessary with a piece or pieces of the same colour xylonite or celluloid to match in
texture, grain etc.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1) The process of covering articles of various shapes with xylonite or celluloid
substantially as hereinbefore described.
(2) The production of xylonite or celluloid articles of various shapes with or without
a central core, without the aid of moulds, presses, dies, or the like and without seams
substantially as described.
