COMPLETE SPECIFICATION.
Improved Two-way Connecting Piece for Hot and Cold Water
Delivery Pipes.
I, EUGEN HEINRICH ERDMANN KLAUSE, of 7-9, Kommandantenstrasse, Berlin,
in the Empire of Germany, Managing Director, 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:-
The arrangement hitherto made use of with delivery pipes or roses for the
mixing of cold and warm water has the disadvantage that the different conduits
come together in a horizontal direction, and their terminations project into the
tube which is provided with an arrangement of rose. In consequence of this
direct impact a thorough mixing cannot take place especially when the outflow
from the two conduits is not equalized, which is what occurs when there is the
smallest inaccuracy in the adjustment of the taps. Thus the cold water would
overcome the flow of the warm water if the cold water tap were opened too wide,
and vice versa. This latter event is the more dangerous as scalding would be
unavoidable..
-
By the arrangement shown in the drawings these objections are obviated ;-
Fig. 1. Sectional elevation of the appliance with the water supply pipes in
view.
Fig. 2. Transverse section at the junction of the conduite.
The essential parts of the appliance are two oblique tubes A, B, running
together formed with a tongue C on their inner side at the point where they
meet which extends as far as the coupling D. This is a screw coupling with a
screw thread for the purpose of attaching to the tube E of the rose or outlet.
The union-nuts a, a¹, and b, b¹ connect by the unions e and c' the conduit G with
the pipe A and conduit G¹ with pipe B.
As is indicated by the arrows the water at different temperatures after the
opening of the taps F, FI would rush together in an oblique direction and would
become mixed as it mounts vertically upwards in the tube leading to the rose.
The tongue C forms a partition right across the diameter of the pipe from the
place where the two conduits A and B join together, preventing thus their mutual
interference of flow and permitting a rising and mixing which is not interfered
with by an opposing current, whether the quantities in the two currents are
equal or different.
The separate streams thus approach each other in a parallel direction in the
common tube which leads to the rose and can equalize their temperature until
they reach an outlet.
The appliance may be made in any kind of metal desired by casting or
turning.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
:-
A two-way connecting piece for hot and cold water pipes having at the point

page_text: of junction of the two tubes (A and B) which run together obliquely, a tongue C
placed perpendicularly, so that the water at different temperatures mounts up
the vertical tube leading to the rose or outlet wherein it is uniformly mixed
substantially as described.
