PROVISIONAL SPECIFICATION.
Improvements in Steam-traps or Apparatus for Drawing off the
Water of Condensation in Steam-pipes.
I, JOSEPH ROTHSCHILD, of 12 Bornwiesenweg, Frankfort-on-the-Main, in the
Empire of Germany, Mechanician, do hereby declare the nature of this invention
to be as follows:-
My invention relates to steam-traps or apparatus for clearing steam pipes from
water of condensation.
In carrying out my invention I provide a vessel in which is a hollow float open
at the top and carrying in the centre of its bottom a vertical tube also open at the
top and communicating through holes at its lower end with the interior of the float.
The tube is closed at the upper end by a valve rigidly connected to an outer concentric
tube kept in position by the outlet tube through which the water of condensation is
ejected and enlarged to receive the valve.
The steam and water from the steam-pipe enter the vessel and the water of
condensation gradually fills the said vessel until it runs over the top edge of the
float and partly fills it. The float is caused by the weight of the water to sink
and thereby draw the inner tube out of the outer tube and away from the valve.
The steam-pressure in the vessel causes the water in the float to pass through the
holes, the inner tube, the valve and the outlet tube until the float again rises and
brings the inner tube against the valve, it being pressed by the steam-pressure
firmly against its seat and kept in position until sufficient water has again entered
the float to lower it and withdraw the inner tube again from its valve-seat.

COMPLETE SPECIFICATION.
Improvements in Steam-traps or Apparatus for Drawing off the
Water of Condensation in Steam-pipes.
I, JOSEPH ROTHSCHILD, of 12 Bornwiesenweg, Frankfort-on-the-Main. in the
Empire of Germany, Mechanician, 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 :-
My invention relates to steam-traps or apparatus for clearing steam pipes
from water of condensation, and is illustrated in the accompanying drawing, in
which :-
Figure 1 is a vertical section; and,
Figure 2 is an elevation of the apparatus :
Figures 3 and 4 are horizontal sections on the lines ab and c d respectively of
Figure 1.
In carrying out my invention I provide a vessel A in which is a hollow float B
open at the top and carrying in the centre of its bottom a vertical tube / also open
at the top and communicating through holes c, d at its lower end with the interior
of the float. The tube his arranged to be closed at the upper end by a valve f
rigidly connected to an outer concentric tube kept in position by the outlet
tube N through which the water of condensation is ejected, and enlarged to receive
the valve f

page_text: The steam and water from the steam-pipe enter the vessel at'm, and the water of
condensation is ejected at n.
The operation is as follows:-
The water of condensation gradually fills the vessel A. until it runs over the top
edge of the float B and partly fills it. The float is caused by the weight of the
water to sink and thereby draw the inner tube h out of the outer tube and away
from the valve f. The steam-pressure in the vessel causes the water in the float B
to pass through the holes c, d, tube h, valve f and tube N until the float again rises
and brings the tube h against the valve f, it being pressed by the steam-pressure
firmly against its seat and kept in position until sufficient water has again entered
the float B to lower it and withdraw the inner tube h again from its valve-seat.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is :-
1. In a steam-trap or apparatus for drawing off the water of condensation in
steam-pipes having a vertically movable floating vessel, which, when sufficiently
overweighted with the water of condensation, causes a valve to open through which
the water of condensation is driven out until the floating vessel ascends far enough
to make contact with the valve, when the steam pressure keeps it in position, the
combination of a tube / in the middle of the float with holes c, d communicating
with the latter, and enclosed by a tube which is fixed through the intervention of
a tube N in the cover, to an outlet n and carries in its enlarged part a valve f
adapted to close the tube h, substantially as set forth.
2. The improved steam-trap or apparatus for drawing off the water of con--
densation in steam-pipes hereinbefore described and illustrated in the accompanying
drawing.
