Improvements in or relating to Superheaters in connection with
Locomotive Steam Bollers.
I, FLORTAN VON GRUBINSKI, of 3, Bracka, Warsaw, Engineer, do hereby declare
the nature of my said invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
This invention relates to locomotive boilers fitted with superheating apparatus,
and its object is to provide means for admitting steam from the boiler to the
superheater, and from the superheater to the steam chest respectively for super-
heating the steam, and for disconnecting the same, as required.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
letters of reference indicate corresponding parts.
Fig. 1, is a longitudinal section of a portion of a locomotive boiler fitted with
my new or improved device.
Fig. 2, is a front view, partly in section.
Fig. 3, is a plan, also partly in section.
A, is the smoke box having a superheater B, of any suitable construction,
built into its upper end, and connected with the inner space of the steam chest d,
by a tube, and with the steam space of the boiler by another tube g. The
steam chest is divided by a horizontal plate a into two separate chambers,
communication being provided for by the passages c, c, when uncovered by the
sliding plate b, as shown in Fig. 1. In the upper part of the steam chest the
steam pipe e extends which conveys the steam to the cylinders, and is provided
in the usual manner with a throttle valve. As shown in Fig. 3, the two pipes g
and h. can be closed by the valves i and f.
The operation is as follows:-When the superheater is required to be thrown
out of action or disconnected, the valve or slide b, is caused to uncover the
ports c, c, as shown in Fig. 1, so that the steam passes directly from the boiler
into the upper space of the steam chest d, through the ports, c, c, of the plate a,
being conveyed thence to the cylinders through the steam pipe e. To completely
prevent the co-operation of the superheater the valve i, is closed, so as to shut
off the admission of steam to the superheater. When however the superheater
is required, the ports c, c, in the plate a, are closed by the slide b, and the valve i,
is opened, the steam then enters the superheater through the pipe g, and is con-
veyed, after it has been superheated, into the upper part of the steam chest by
the pipe h, whence it is carried, through the steam pipe e, to the cylinders.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
In a locomotive steam boiler fitted with superheaters, the combination there-
with of a device for connecting and disconnecting the superheater by the divi-
sion into two spaces of the steam chest d, by a plate a, having one or more port

page_text: or ports c, and a slide b, the lower of such spaces being connected with the super-
heater by a pipe, so that the superheated steam can be conveyed into the upper
part of the steam chest by a second. pipe, whence it proceeds to the cylinders;
the superheater being thrown out of action or disconnected by opening tho
slide valve b and closing the tubular connection between the boiler and the
superheater, substantially as herein before described and illustrated by the
drawings.
