MOULET, of Marseilles, and EMIL GINOYER, of Marseilles, all in the Republic of

PREVENTING DEPOSITS OR INCRUSTATION IN STEAM AND OTHER BOILERS, AND IN
CLEANSING SUCH [BOILERS." Partly a communication from abroad by Messrs.
Frederick Blanc and Porte, père, of St. Etienne, Department of the Loire, France.
This Invention relates to the prevention of incrustation in steam boilers, and the
cleansing such boilers when incrustation has already taken place. In carrying out
this Invention we place in the boiler a quantity of wheat bran. We have found
about 2 lbs. of bran to each horse power of the boiler to be effective. The effect of
this addition of bran is to prevent altogether any formation or incrustation upon
the boilers, and also to remove incrustation upon boilers which have already been
in use, and whether such incrustation has arisen from the use of fresh or of salt
water. Although wheat bran is mentioned alone, and is found very effective for
the purpose, other preparations of cereals of various kinds possessing the same
properties may be employed. When the water in the boiler fresh water a little
salt may be added.

MOULET, of Marseilles, and EMIL GINOYER, of Marseilles, all in the Republic of

PREVENTING DEPOSITS OR INCRUSTATION IN STEAM AND OTHER BOILERS, AND IN
CLEANSING SUCH BOILERS." Partly a communication from abroad by Messrs.

Our Invention relates to the prevention of deposits or incrustation in steam and
other boilers, and to the cleansing of such boilers when incrustation has already
taken place, and also to the prevention of what is termed "pitting," which consists
of cellular indentations produced in the boiler plates under the action of very high
pressure steam. In carrying out our said Invention we place in the boiler a
quantity of wheat bran. We have found about two pounds of bran to each horse
power of the boiler to be effective, and sufficient to serve for the space of about
three weeks. The effect of this addition of bran is to prevent altogether any
formation or incrustation upon the boilers, and also to remove incrustation upon
boilers which have already been in use, and whether such incrustation has arisen
from the use of fresh or of salt water. The bran may be introduced into the boiler
either by hand through the manhole, or elsewhere by the ordinary feed or other
pump or injector, and by preference from a separate well or receptacle, in which
the bran along with water is already placed.
When the water in the boiler is fresh water a little salt or soda may be added.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried into
effect, we would observe in conclusion that what we consider to be novel and
original, and therefore claim as the Invention secured to us by the hereinbefore
in part recited Letters Patent is,―
The employment of wheat bran in steam and other boilers, substantially as and
for the purposes herein before described.
In witness whereof, we, the said Eugene Arnaud, Fils, Joseph Moulet, and
Emil Ginoyer, have to this our Specification set our hands and seals, the
Fifteenth day of November, One thousand eight hundred and eighty.
