COMPLETE SPECIFICATION.
An Improved Coupling for the Steam Pipes used for Heating
Railway Carriages.
I, FRANZ KÉMÉNTZY Junior of Budapest, IV. Bez. Grüne Baumgasse 20,
Austria Hungary, 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:-
The coupling of this invention consists of a number of tubular metal parts
jointed together so as to yield in all directions and is designed to supersede the
coupling of elastic material usually employed.
In the accompanying drawing
Fig. 1 is a side view shewing a complete steam heating pipe coupling of this
invention carried between two railway vehicles.
Fig. 2 is a top view..
The remaining figures refer to modifications and details.
Each coupling is composed of two similar sets of parts, one set forming one half
of the coupling extending from the end of one railway carriage and the other set
the other half of the coupling extending from the other railway carriage, the two
free ends being connected together to form the coupling by means of a flanged
casing.
a are elbow pieces each with stuffing box outlet c and four way cock d with
valve e for water of condensation which may at any time be opened by key at f
(Figs. 3, 4). Each elbow piece a carries an elbow tube in stuffing box securely
held in the same by gland h (Fig. 5) packing i and screwed on steel ring j. Elbow
or bend g has an enlargement k forming with a gland and metallic packing ring, a

page_text: stuffing box for ball ended tube l, the spherical surface coming against the packing
ring as a seating and in such a way as to allow of lateral movements. Ball ended
tube is by one or more tubes of suitable length and by screw and lock nut connec-
tion, connected to tubular casing m (Figs. 1, 2, 6, 7). This casing is constructed
with stuffing box, screw gland n and cover o and receives through a divided or two
part screw collar p a flange pipe 7 turning on the inner surface of collar as a
bearing. When the two flanges are placed together, metallic or other suitable
packing or material for making a joint is placed in between them.
In this way
the flange pipes may move round one axis in the same or opposite directions.
means of the projecting rim on each flange and spring levers R the two flange
pipes and with them the casings m are held so firmly together that they cannot of
themselves come apart when in use. el (Fig. 6) is a valve. for the water of
condensation.
By
The construction shewn in Figs. 8 and 9 is not substantially different from that
herein before described. Elbow with enlargement for stuffing box is done away
with and a vertical joints and stuffing box t substituted. v is a second link which
has a horizontal movement in stuffing box v¹.
The modified construction shewn in Figs. 10, 11, differs from the foregoing only
in that instead of the combinations shewn in Figs. 5 and 9 a vertical, horizontal
and also a lateral movement is obtained with the several straight and ball links or
joints. The elbow a and stuffing box as shewn in Figs. 8, 9, receives a bend w
with enlargement w', forming with other accessories a stuffing box in which is
carried ball ended pipe y.
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. As a substitute for coupling tubes of elastic material for railway vehicles,
etcetera, a combination of jointed metal tubes in two sets each set capable of turning
independently of the other and both sets connected to a central casing closed
airtight on the outside, communicating with the carriage tubing through airtight
connections capable of turning on different axes, substantially as described and
shewn.
2. In the tubular coupling referred to a disengageable airtight connection
consisting of turning discs or flanges provided with projecting rims, in combina-
tion with spring levers or handles, which connection allows of the turning of the
combined tubes in one plane, substantially as described and shewn.
3. In the tubular coupling referred to the four way cock d substantially as
described and shewn.
