Year: 1881

page_text: LETTERS PATENT to Arnold Budenberg, of the City of Manchester, in
the County of Lancaster, Mechanical Engineer, for an Invention of
"IMPROVEMENTS IN INJECTORS." A communication from abroad by
Christian Frederick Budenberg and Bernhard August Schaeffer, of Buckau-
Magdebure in the German Emnira
PROVISIONAL SPECIFICATION left by the said Arnold Budenberg at the
Office of the Commissioners of Patents on the 12th April 1881.
ARNOLD BUDENBERG, of the City of Manchester, in the County of Lancaster,
Mechanical Engineer. "IMPROVEMENTS IN INJECTORS." [A communication from
abroad by Christian Frederick Budenberg and Bernhard August Schaeffer, of
Buckau-Magdeburg, in the German Empire.]
This Invention has for its object the construction of an injector which shall be
capable of working with warmer water than the ordinary injector, and thus to
allow the waste heat of the boiler or of the exhaust steam to be utilized to a
greater extent than hitherto.
In order to carry out the Invention the water inlet of the injector is divided
for the whole or a part of its length by one or more partitions. Within the con-
densation chamber of the injector one or more additional nozzles are inserted in
such a manner that the condensation chamber is divided by the flanges of the
nozzles into as many smaller chambers as there are passages in the water inlet.

by the said Arnold Budenberg in the Great Seal Patent Office on the

Mechanical Engineer. "IMPROVEMENTS IN INJECTORS." A communication from
abroad by Christian Frederick Budenberg and Bernhard August Schaeffer, of
Buckau Magdeburg, in the German Empire.
This Invention has for its object the construction of an injector which shall be
capable of working with warmer water than the ordinary injector, and thus to
allow the waste heat of the boiler or of the exhaust steam to be utilized to a greater
extent than hitherto.
In order to carry out the Invention the water inlet of the injector is divided
for the whole or a part of its length by one or more partitions. Within the con-
densation chamber of the injector one or more additional nozzles are inserted in
such a manner that the condensation chamber is divided by the flanges of the
nozzles into as many smaller chambers as there are passages in the water inlet.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shows an external view of the injector; Fig. 2 represents a longitudinal
section, and Fig. 3 a transverse section taken through the water inlet, which is
divided into two portions A and A' by means of a partition cast in one with the
injector. The condensation chamber B has an additional nozzle C, the flange of
which is seated for a part of its circumference on the inner end of the partition
dividing the water inlet; the point of this nozzle is inserted within the combination
nozzle Ď. Although one additional nozzle and one partition in the water inlet
only are shown two or more may be employed. The action of the injector is
precisely similar to that of the injector for which Letters Patent, No. 327, of
A.D. 1874, have been granted to me, only that in consequence of the improvement
herein before described warmer water may be employed for the feed.
Having thus described the nature of this Invention, and in what manner the
same is to be performed as communicated to me by my foreign correspondents, I
claim,-
An injector having more than one condensation chamber with a separate water
inlet to each chamber.
In witness whereof, I, the said Arnold Budenberg, have hereunto set my
hand and seal, this Eleventh day of October, in the year of our Lord One
thousand eight hundred and eighty one.
