page_text: LETTERS PATENT to Herbert John Haddan, of the Firm of Herbert and
Company, Solicitors of Patents, of 67, Strand, in the City of Westminster,
Civil Engineer, for an Invention of "AN IMPROVED COMPOUND FOR
PREVENTING THE INCRUSTATION OF BOILERS." A communication from abroad
by Hermann Heimann, of Cologne, in the German Empire.
PROVISIONAL SPECIFICATION left by the said Herbert John Haddan at
.
the Office of the Commissioners of Patents on the 16th March 1880.
HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. "AN
IMPROVED COMPOUND FOR PREVENTING THE INCRUSTATION OF BOILERS." A com;
munication from abroad by Hermann Heimann, of Cologne, in the German
Empire.
The Invention consists in the application of roasted and ground coffee (seed of
the coffee tree) either alone or mixed with one or more of the following substances,
viz.: Lupine (seed of Lupinus L.) and leutils (Ervum L.), fruit and bark of oak
(Quercus L.), chicory (roots of Cichorium L.)
These substances may be used either raw or roasted. There may also be added
extracts from the wood of acacia catechu, the branches of uncaria gambia, the seed
of areca catechu, and various European pine trees, which extracts are known under
the name of catechu or new catechu. Chloride of baryta or chalk, or both, may
also be added to the coffee beans.
The said substances (ground coffee and admixtures) may be introduced into the
water when the latter is already in the boiler. The quantity of the substances and
the choice of the admixtures depends in each case on the impurities dissolved in the
water;
and in order to convert the said ingredients or compound into an article of
manufacture suitable for sale, preservation, and use, they are treated as follows:--
The various components, among which roasted coffee beans form the major
portion, are ground and sieved so as to obtain a uniform product, and subsequently
well mixed together. The so obtained powder. is converted into a stiff paste by the
admixture of an aqueous solution of dextrin, with or without some glycerine, and
the paste formed into globulous or otherwise shaped pieces, preferably, by means
of a press of any suitable and known construction. These pieces are then dried
and packed in waterproof paper or other-suitable material to make them ready
for sale.

means of a press of any suitable and known construction. These pieces are then
dried and packed in waterproof paper or other suitable material to make them
ready for sale.
CLAIM.
The addition of roasted and ground coffee beans, either alone or mixed with one 3
or more of the substances nained under No. 1 to 5, to the water used in boilers,
for the purpose of preventing the incrustation of the latter, substantially as
described.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
