LETTERS PATENT to Charles Max Sombart, of the Firm of Buss, Sombart, and
Company, Engineers and Patent Agents, of Magdeburg, in the Empire of
Germany, for an Invention of "IMPROVEMENTS IN INJECTORS."
munication from Carl Louis Strube, of Buckau, near Magdeburg, in the
Empire of Germany..
PROVISIONAL SPECIFICATION left by the said Charles Max Sombart at the
Office of the Commissioners of Patents on the 28th May 1880.

and Patent Agents, of Magdeburg, in the Empire of Germany.
IN INJECTORS." A communication from Carl Louis Strube, of Buckau, near
Magdeburg, in the Empire of Germany.
The improvements consist in the novel construction and arrangement of an
adjustable steam nozzle, by means of which the admission of water is regulated,
and the injector rendered capable of working under variable steam pressure; also
admission and shut off of steam produced by one and the same spindle; also in
the construction and arrangement of the said nozzle, whereby the regulation of the
water and shutting off of the admission of steam and water are simultaneously
effected; also the arrangement of a ball in the pressure nozzle in such manner that
it serves as a back pressure valve; also in the shape of the main body of the
injector, by which the axes of the steam and water admission branches concide.
The improvements are performed by fixing the spindle within the steam nozzle
or making it of one piece with the nozzle, or it may be separated from the nozzle.
The nozzle is provided with a conical fitting, whereby a perfect shut off of steam
towards the water side is secured, as well as a tight fitting towards the stuffing
box. Sometimes the stuffing box is dispensed with, and a perfectly fitting collar
used to produce a shut off.
A separate valve for shutting off the steam is dispensed with, as the same spindle
serves for regulating simultaneously the water admission, together with the
shutting off of the steam and section nozzles, and the water and steam being shut
off simultaneously the usual adjusting cock and valve for shutting off the steam
are dispensed with. In other respects the injectors and their parts are made as
at present.

CHARLES MAX SOMBART, of the Firm of Buss, Sombart, and Company, Engineers
and Patent Agents, of Magdeburg, in the Empire of Germany. IMPROVEMENTS
IN INJECTORS." A communication from Carl Louis Strube, of Buckau, near
Magdeburg, in the Empire of Germany.
The new and peculiar part of the injector, represented by Figures 1 to 6 of the
annexed Drawings, consists chiefly of the arrangement of the moveable steam-
nozzle D, by means of which the admission of the water is regulated and the
injector is allowed to work with variable pressure of steam. Water is admitted
at B, steam at A. Figures 1, 2, and 6 show the spindle C fastened within the steam-
nozzle D; Figures 3 and represent the spindle C as made of one piece with the
steam nozzle, whilst in Figure 5 the spindle C is separated from the steam nozzle D.
These various combinations have to fulfil certain conditions. For instance, of an
injector shown in Figures 1, 2, 3, and 6, the steam nozzle D provided with a conical
fitting has to effect, when the injector is at rest, a perfect shut off of the steam
towards the water side. With an arrangement shown in Figure 4 the stuffing box
can easily be packed when the apparatus is at rest, because the steam nozzle D
provided with a cone at its superior part secures a tight fit towards the stuffing box.
In the arrangement Figure 5 there is no stuffing box, and therefore no packing
wanted, because the exactly fitted collar of the spindle C produces a perfect shut
off. In the injector shown in Figures 4, 5, and 6, a small ball F in the pressure-
nozzle is substituted for the usual back pressure valve; the injector is thus
considerably simplified. All the injectors represented in the Drawings are
arranged in such a manner that a separate valve for shutting off the steam is not
wanted. The same spindle regulating the admission of water serves simultaneously
for the opening and shutting of the steam nozzle D and of the sucking nozzle E.
The water flows to the injector shown in Figure 2, and the arrangement in this case
is made in such a manner that water and steam are shut off simultaneously, whence
the adjusting cock for the water and the valve for shutting off the steam is not
wanted
CLAIMS.
1. The construction and arrangement of the adjustable steam nozzle, by means
of which a regulation of the water and the admission and shut off of steam is
produced through one and the same spindle, as shown in Figures 1, 3, 4, 5, and 6.
2. The construction and arrangement of the adjustable steam nozzle, by means
of which a regulation of the water and simultaneously a shutting off of steam and
water is effected, as shown in Figure 2.
In witness whereof, I, the said Charles Max Sombart, have hereunto set my
hand and seal, this Fifteenth day of November 1880.
