COMPLETE SPECIFICATION.
Improvements in and relating to Hose Unions..
I, ERNST STORCH of 12 Victoriastrasse, Breslau in the Kingdom of Prussia
and German Empire, 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 :-
This invention relates to unions for attaching hose pipes to water taps and similar
articles or for attaching two hose pipes together, and its object is to enable a tight
joint to be rapidly made when, as in the case of fire, every moment is of great
importance.
A union constructed to embody these improvements has within it a suitably
shaped indiarubber or similar packing washer which is kept firmly pressed around
the tap bib or other part of the pressure of the water.
In the accompanying drawings by reference to which the description of my
invention will be more readily understood,
Figure 1 illustrates a section of the improved union attached to an ordinary
water tap;
Figures 2 and 3 shew the union in front elevation and plan respectively;
Figure 4 illustrates the method of connecting together two hose pipes;
Figures 5 and 6 are respectively a section and elevation of a modified form of
union and method of attachment; and
Figure 7 illustrates an alternative form of the fastening.
Another modification of the union is shewn in elevation in Figure 8.
As shewn by the figures the union consists essentially of three parts the packing
ring and the parts e and a of which the upper part e contains the conical or funnel
shaped packing ring b as illustrated in Figures 1 and 4, where the two parts a e of
the union are shewn screwed together gripping the ring between them, and thus
ensuring an absence of leakage at the joint. The upper part e of the union is in
this case furnished with a bracket or extension c which engages with the under side
of the tap, and a loop d pivoted by the screws and arranged to be pushed over the
bib of the tap and hold the union securely in place. A ring s is secured to the bib
in the most suitable place as found by trial in the manner illustrated by Figures 1
and 1 so as to engage with the loop and prevent its accidental removal.
The bib of the tap or the end of the pipe is inserted in the opening in the top of
the union and passes through the rubber packing ring. When the water is turned
on, some of it fills the chamber in a and presses the ring tightly on to the pipe or
bib to prevent leakage.
Figure 4 illustrates the method of joining two hose pipes or of attaching a hose
pipe to a straight water pipe. The nozzle M has formed upon it two arms g g
which engage with slots formed in the two links d d which are equivalent to the
loop d Figure 1 and which are similarly secured to the union by the screws ƒ ƒ.
In this and in the other modifications illustrated and described, the hose is secured
upon the nozzles n n in the usual manner.
In the modification shewn in Figures 5 and 6 the loop d is provided with a
screw which engages with a step or projection formed or secured on the bib, and
thus secures the union in place. The rubber packing ring 6 in this case has a
modified form as shewn, and offers two bearing surfaces to the bib M. An excentric F
may be substituted for the screw v as shewn in Figure 7.
The union illustrated by Figure 8 is somewhat similar to that shewn in Figure 1
but is without the extension c.
It will be obvious that unions constructed as hereinbefore described may he

page_text: equally well adapted for connecting hose for conveying air steam or other fluids as
for water pipes.
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 I
claim is,―
•
1. A hose union constructed and arranged substantially as hereinbefore described
and as illustrated by the accompanying drawings.
2. The combination in a hose union of an upper and lower part connected
together, an indiarubber packing ring, and a link or loop for securing the union
upon the bib pipe or nozzle; constructed and arranged substantially as hereinbefore
described and as illustrated by the accompanying drawings.
Dated this 19th day of May A.D. 1892.
