IMPROVEMENTS IN COMPOUNDS, PUTTIES, OR CEMENTS APPLICABLE FOR JOINTS AND JOINT PACKINGS IN VAPOUR ENGINES AND OTHER ENGINES AND APPARATUS, ALSO APPLICABLE TO THE JOINING OF SUBSTANCES, AND AS A PLASTIC ORNAMENTAL COMPOSITION."
Year: 1880

page_text: LETTERS PATENT to Israel Rudolf Blumenberg, of Washington, District of
Columbia, United States of America, but at present of 33, Chancery Lane, in
the County of Middlesex, Engineer, for an Invention of "IMPROVEMENTS IN
COMPOUNDS, PUTTIES, OR CEMENTS APPLICABLE FOR JOINTS AND JOINT
PACKINGS IN VAPOUR ENGINES AND OTHER ENGINES AND APPARATUS, ALSO
APPLICABLE TO THE JOINING OF SUBSTANCES, AND AS A PLASTIC ORNAMENTAL
COMPOSITION."
PROVISIONAL SPECIFICATION left by the said Israel Rudolf Blumenberg
at the Office of the Commissioners of Patents on the 30th December 1880.
ISRAEL RUDOLF BLUMENBERG, of Washington, District of Columbia, United
States of America, but at present of 33, Chancery Lane, in the County of
Middlesex, Engineer. "IMPROVEMENTS IN COMPOUNDS, PUTTIES, OR CEMENTS
APPLICABLE FOR JOINTS AND JOINT PACKINGS IN VAPOUR ENGINES AND OTHER
ENGINES AND APPARATUS, ALSO APPLICABLE TO THE JOINING OF SUBSTANCES,
AND AS A PLASTIC ORNAMENTAL COMPOSITION."
The chief object of this Invention is to produce a compound which shall resist
the dissolving influence of the vapours of bisulphide of carbon, ammonia, and other
fluids of the same class used for motor purposes, and which shall also resist the
influence of dampness or moisture and of high heat, and of the expansion by heat
and the contraction of the parts to which it is applied. The aforesaid bisulphide
of carbon vapours especially are of so penetrating a nature as to force their way
through any rust joints, or any faults in the metallic parts with which they are in
contact; and packings and joints as heretofore made and known have been sources
of constant trouble in such vapour engines.
I employ the oxide of lead known as litharge, and by preference the yellow
litharge, in combination with glycerine and lampblack, as the main ingredients in
my compound as applied to vapour engines. The lampblack and the glycerine are

page_text: first well mixed in about the proportion of half an ounce of the former to a pint of
the latter; this liquid is then mixed with the litharge and thoroughly kneaded and
worked into a thick paste, which, when applied as a putty to parts of the engine
exposed to the vapours of the aforesaid volatile liquids as required, completely
resists their action; it is also used for the screwed and other joints, and for coating
of or combining with the asbestos, millboard, or other suitable packing; also for
forming the joints of surface condenser and other tubes with their tube plates.
When applied as a coating and when set, which takes place in the ordinary way
in a few hours, it takes the form of an enamel; by the application of heat it sets
quicker.
When used for these purposes, or when used as a joining cement for iron, wood,
china, and many other substances, or when used as a plastic compound for
ornamental purposes, mixed with pigments or not, it should be made when required
for use, but it may be combined with a solvent for the purpose of being kept in
tins or other airtight receptacles ready for use, the solvent evaporating under the
influence of air or heat.

by the said Israel Rudolf Blumenberg in the Great Seal Patent Office on

influence of air or heat.
And having thus described and ascertained the nature of this Invention, I declare
that I claim,
The litharge, lamp black, and glycerine compound, cement, or putty produced
and applied for the purposes set forth, substantially as described.
In witness whereof, I, the said Israel Rudolf Blumenberg, have hereunto set
my hand and seal, this Thirteenth day of June, in the year of our Lord
One thousand eight hundred and eighty-one.
