the Office of the Commissioners of Patents, with his Petition, on the
8th March 1860.
I, CHRISTOPHE FRANÇOIS DELABARRE, Knight of the Legion of Honor &
Civil Engineer, of Neuilly, near the City of Paris, in the Empire of France,
do hereby declare the nature of the said Invention for "IMPROVED APPARATUS
TO BE USED IN PROPELLING GASES & FORCING LIQUIDS," to bo as follows:-
This Invention, being improvements on a former Invention of mine for
which Letters Patent No. 346, dated the 15th of Feby. 1855, were granted
to me, consists of certain mechanical arrangements or apparatus by which
gases or liquids may be acted on by attraction or propulsion, & 1 use these
methods to force water into steam generators or boilers in place. of pumps, as
at present employed, as also in the blowing apparatus, both of which are
described in my said before mentioned Patent to which I refer as hitherto
manufactured by me. These additional improvements in propelling gases &
forcing liquids into any medium whatever, & in my my blowing apparatus may
be briefly described by referring to the general character of the apparatus repre-
sented in the Drawings accompanying my said before mentioned Specification
of my Patent, No. 346, A.D. 1855, which apparatus I now modify & improve
in various ways so as to render them, as to the first mentioned improvements,
capable of receiving or attracting a column of water, liquid, air, or any elastic
gas, & directing this column against a medium of any pressure that may be
desired; said attraction or direction of water, liquid, air, or any clastic gas being

page_text: performed through the agency of one or more jet or jets, stream or streams of
steam or other elastic fluid through a pipe or pipes, tube or tubes.
In my improved apparatus I direct this jet or jets, stream or streams into
a tubular space into which the water, liquid, air or any elastic gas enters
cither by partial vacuum created by the jet or jets, stream or streams of
steam or other elastic fluid or by head pressure, and in either of these cases
is propelled with great dynamic momentum against any statical pressure of
any power that it may be desired to overcome, & against which the water,
liquid, air, or any elastic gas has to be forced. The particular arrangements
& combinations of steam, water, liquid, air, or elastic gas, pipes of suitable
bores & dimensions, air boles, cocks, valves, &c., constitute this part of my
present improvements on the corresponding parts of my before-mentioned
Patent.
The apparatus herein-before described for forcing liquids into steam
generators or boilers is also made self-acting by combining it with a float
actuating a rack & pinion or other mechanical arrangements.
The second part of my present improvements consists of various modi-
fications which I have made in the position, shape, and relative dimensions of
the blowing apparatus described in my before mentioned Patent. These
modifications consist in applying two blowing apparatus, one at each side,
whenever the grate or furnace is of some considerable length. The blowers
may also be so directed as to act upon the top surface of the fire. Instead of
placing the apparatus so as to blow in a horizontal direction, I so fix them
as to act at any desired angle, either under or above the grate or furnace.
The change in the relative dimensions consists in so contriving the apparatus
that a greater or lesser quantity of air may be admitted as compared with the
quantity of steam or other elastic fluid or gas, according to the nature of the
fuel used or construction of the furnace. The object of the modifications as
relates to the shape of blowing apparatus is partly to render the same more
portable, as well as at the same time to afford greater facilities for fixing
them.
