THE APPLICATION OF GLASS, CRYSTAL, OR OTHER VITREOUS MATERIAL, OR OF EARTHENWARE (CÉRAMIQUE), TO CERTAIN PARTS OF MACHINERY
Year: 1854

page_text: LETTERS PATENT to Rudolph Bodmer, of 2, Thavies Inn, Holborn, in the
City of London, for the Invention of "THE APPLICATION OF GLASS, CRYSTAL,
OR OTHER VITREOUS MATERIAL, OR OF EARTHENWARE (CÉRAMIQUE), TO CERTAIN
PARTS OF MACHINERY" - (A communication).
PROVISIONAL SPECIFICATION left by the said Rudolph Bodmer at the
Office of the Commissioners of Patents, with his Petition, on the 18th
July 1854.
I, RUDOLPH BODMER, of 2, Thavies Inn, Holborn, in the City of London,
do hereby declare the nature of the said Invention of "THE APPLICATION OP
GLASS, CRYSTAL, OR OTHER VITREOUS MATERIAL, OR OF EARTHENWARE (CÉRAMIQUE),
TO CERTAIN PARTS OF MACHINERY," (a communication,) to be as follows:- :
It consists in manufacturing the steps, sockets, and bearings of locomotive;
marine, and other steam engines of railway carriages, and of all kinds of
machinery of glass, crystal, or other vitreous material, or of earthenware
(céramique). These steps, sockets, and bearings are formed in moulds and
then subjected to the process of annealing; they may be used either in the
state in which they leave the mould, or finished by cutting, grinding, or polishing,
according to circumstances.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Rudolph Bodmer in the Great Seal Patent Office on the
18th January 1855..
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RUDOLPHI
BODMER, of 2, Thavies Inn, Holborn, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of July, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Rudolph Bodmer, Her special licence that I, the said Rudolph Bodmer,
my executors, administrators, and assigns, or such others as 1, the said
Rudolph Bodmer, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all tinies thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "THE APPLICATION OF
GLASS, CRYSTAL, OR OTHER VITREOUS MATERIAL, OR OF EARTHENWARE (CÉRAMIQUE),
TO CERTAIN PARTS OF MACHINERY," (a communication by a foreigner residing
abroad), upon the condition (amongst others) that I, the said Rudolph
Bodmer, by an instrument in writing under my hand and seal; should par-
ticularly describe and ascertain the nature of the said Invention, and in what
manner the same was be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Rudolph Bodmer, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
In every description of machinery those parts which are exposed to friction
turn or slide in or upon steps, sockets, or bearings, which have hitherto been
made of metal, such as iron, brass, various amalgams, and sometimes even of
wood or other materials. In order to reduce the friction, the wear and tear,
and to effect the utmost economy in the use of lubricating materials, it is of
importance to select that substance which is best calculated to effect these
objets. Now, the Invention which has been communicated to me consists
in the application of glass, crystal, and other vitreous material, or of earthen-
ware (céramique), as such substance, and as the most suitable substitute for
metal or other materials in the manufacture of steps, sockets, or bearings.

page_text: These steps, sockets, or bearings may be cast or formed in moulds of any
desirable shape, and used either in their rough state, or they may be cut or
ground and polished, and they may, if found desirable, be annealed previous
to being used. They may be fixed in the usual manner; and in order to pre-
vent vibration they may be packed with or placed upon cloth, caoutchouc, or
other slightly yielding or elastic material.
Having now described the nature of the Invention which has been commu-
nicated to me, I wish it to be understood that I claim as the Invention secured
to me by Letters Patent, the application of steps, sockets, or bearings made
of glass, crystal, or other vitreous material, or of earthenware (céramique), to
all kinds of machinery whatsoever, and especially to the rolling stock and
fixed machinery of railways, and to stationary and marine steam engines, and
to shafting and gearing.
In witness whereof, I, the said Rudolph Bodmer, have hereunto set my
hand and seal, this Thirteenth day of January, One thousand eight
hundred and fifty-five.
RUDOLPH BODMER. (L.B.)
