We, CARL BERTENBURG, Printer, and CLEMENS FELLER, Hotel Proprietor, both
of 90, Bahnhofstrasse, Gelsenkirchen, in Westphalia, German Empire, do hereby
declare the nature of this invention to be as follows:-
In appliances for jointing water pipes valves or such like, with hoses or the
like great difficulties are encountered in tightening the union-joints.
In this invention means are provided for automatically tightening the union-
joint by the pressure of the water.
In Figs. 1 and 2 of the accompanying drawing an illustration is given of
the joint of a valve with a junction piece of a hose or the like. Figs. 4, 5, 6
and 7 show different modification of the arrangement shown in Figs. 1 and 2.
Instead of a valve the junction piece may be fastened to another junction
piece, to a pipe or the like.
As
The junction piece B consists of a funnel shaped box a a packing ring b and
a cap c, which serves for fastening the packing ring b to the box a. The
valve A has a conical outlet d which fits into the packing ring b. In order to
joint the piece B to the valve A, it is pushed over the outlet d of the same.
soon as the valve A in connection with the junction piece B is opened, the
water will enter the box a and will press the packing ring b against the outlet d
of the valve, so that a perfectly tight junction will be effected. In order to
avoid the falling off of the junction piece B it is fastened by any suitable means
to the valve. In the construction shown in Figs. 1 and 2 the junction piece B
is provided with a hook e, which grips behind a rip f of the valve.
In Figs. 3, 4 and 5 a construction is shown, in which two hooks e¹ and e² are
provided, which can be inserted through cut-out grooves hh' of a flange fi of
the outlet d', whereafter the piece B' can be turned. The hooks ele2 will slide
then on the 'bevelled front side of said flange until they snap into grooves gg¹
and are held thereby in their proper position.
In the construction shown in Figs. 6 and 7 the junction piece is fastened to
the flange f2 of the valve by means of a common union nut which fits on the
thread of the outlet of the valve or the junction piece to which it shall be
fastened.

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:
In appliances for jointing water pipes, valves or the like with hoses or the
like, great difficulties have hitherto been encountered in tightening the union-
joints.
In this invention means are provided for tightening the union-joint, which
are rendered self-acting by the pressure of the water.
In Figs. 1 and 2 of the drawings which accompanied the Provisional Specifi-
cation an illustration is given of the joint of a valve with a junction piece of
a hose or the like. Figs. 4, 5, 6, and 7 show different modifications of the
arrangement shown in Figs. 1 and 2.
Instead of a valve the junction piece may be fastened to another junction
piece, to a pipe or the like.
As
The junction piece B consists of a funnel shaped box a a packing ring and
a cape, which serves for fastening the packing ring to the box a. The
valve A has a conical outlet d which fits into the packing ring b. In order to
joint the piece B to the valve A, it is pushed over the outlet d of the same.
soon as the valve A in connection with the junction piece B is opened the
water will enter the box a and will press the packing ring b against the outlet d
of the valve, so that a perfectly tight junction will be effected.
avoid the falling off of the junction piece B it is fastened by proper means
to the valve. In the construction shown in Figs. 1 and 2 the junction piece B
is provided with a hook e, which grips behind a rib f of the valve.
In order to
In Figs. 3, 4 and 5 a construction is shown, in which two hooks e and e² are
provided, which can be put through cut-out grooves hh of a flange fl of
the outlet d', whereafter the piece B¹ can be turned. The hooks ele² will slide
then on the bevelled front side of said flange until they snap into grooves 9 g¹
and are held thereby in their proper position.
In the construction shown in Figs. 6 and 7 the junction piece is fastened to
the flange f of the valve by means of a common union nut which fits on the
thread of the outlet of the valve or of the junction piece, to which it may be
fastened.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
-
1. In a self-closing union-joint, the arrangement of a packing ring which
fits over a conical outlet, and which is pressed by the water against this outlet,
substantially as set forth.
2. In a self-closing union-joint as claimed in Claim 1, with means for
preventing the falling off of the union piece.
3. In a self-closing union-joint as claimed in Claim 1, the arrangement of
one or several hooks on the junction piece, which grip behind ribs or flanges
of the valve, or of the other junction piece, to which the first one shall be
fastened.
4. In a self-closing union-joint as claimed in Claim 3 the arrangement of

page_text: grooves gg¹ in the ribs or flanges, for the purpose of holding the hooks in their
position.
5. In a self-closing union-joint as claimed in Claim 1, the arrangement of a
common union-nut on the junction-piece, which nut fits on the thread of the.
outlet of the valve or of the other junction piece, to which the first one shall
be fastened.
