PROVISIONAL SPECIFICATION.
A Method of Regenerating Steam as a Working Fluid, and Apparatus
for that purpose.
I, HIERONIMUS VAN HEUMEN, of Delft, in the Kingdom of Holland, Mechanical
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to regenerate steam after it has given up a portion
of its energy as a working fluid, so as to render it capable of operating again
and again.
For this purpose I generate steam in any suitable boiler in the usual way, and
from this boiler I conduct the two portions of the steam, the one portion going to
work an engine, the other portion going to a superheater in which its temperature
is considerably raised. The exhaust steam from the engine at a pressure which
may be considerably below that in the boiler is conducted to a recipient provided
with an injector and connected by pipes with the superheater and the boiler. The
superheated steam issuing at high velocity from the nozzle or nozzles of the
injector draws steam from the recipient and drives it towards the boiler with
sufficient pressure to effect its return.

A Method of Regenerating Steam as a Working Fluid, and Apparatus
for that purpose.
I, HIERONIMUS VAN HEUMEN, of Delft, in the Kingdom of Holland, Mechanical
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:
-

and again.

The

page_text: superheated steam issuing at high velocity from the nozzle or nozzles of the
injector draws steam from the recipient and drives it towards the boiler with
sufficient pressure to effect its return.
Fig. 1 of the accompanying drawings is a vertical section, and Fig. 2 is a
sectional plan partly central and partly on the line 2-2 of Fig. 1 of the recipient
and injector. Fig. 1 is an elevation of part of Fig. 1 beyond the line X and
Fig 2 is a sectional plan of part of Fig. 2 beyond the line Y, these parts being
shewn separated in order to shorten the drawing.
Fig. 3 is an elevation of one of the inlet pieces of the injector. A is the recipient
vessel which the waste steam to be regulated enters by the opening B. The super-
heated steam enters the injector at C, its issue from the nozzle of the injector being
regulated by the adjustable conical core D. Beyond the nozzle there are a number
of trumpet mouthed inlets E for the waste steam. Each of the inlet pieces is made
with four projections e on each side these being shouldered so that the projections
of each piece E fit against those of the next piece in order. Outside of the row of
inlet pieces E is a sliding tube F, which in the position shewn in Fig. 2 covers and
closes all the inlets. A ring f. at its end is connected by links G to arms H fixed
on a rocking spindle I which passes through a stuffing box J and has fixed on it
an external hand lever L. As this lever is moved the tube F is caused to take
various positions, closing all the inlets E as shewn in Fig. 2, or closing half of
them as shewn in Fig. 1 or leaving them all or any number of them open. Beyond
the row of inlets the injector has a mouth M and taper tube T of the usual form, so
that the velocity of the fluid determined by the injector action of the superheated
steam is converted into pressure.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The herein described method of regenerating waste steam from an engine by
subjecting it to the injector action of superheated high pressure steam.
2. In apparatus for regenerating waste steam the combination of a recipient
vessel for the waste steam and an injector with numerous inlets for the waste
steam, substantially as described.
