Marine Engineer do hereby declare the nature of the said Invention for IMPROVE.
MENTS IN UNIONS OR COUPLINGS FOR PIPES, HOSE AND OTHER ARTICLES to be as
follows:-
The Invention has for its object improvements in unions or couplings for pipes,
hose and other articles and relates to a novel construction of parts whereby great
facility is afforded for connecting two lengths of pipe or hose or for coupling
together other articles.
When employing the ordinary screw coupling several turns of the coupling piere
are necessary in order to effect a solid union of the parts and also to disconnect the
same and frequently considerable difficulty is experienced in causing the internal
thread of the coupling socket, to screw correctly on to the external screw formed
on one of the parts to be connected.
According to my present Invention I so construct the parts that the internal
thread of the coupling socket always remains connected with the aforesaid external
screw whilst the connection and disconnection of the parts are readily effected by
only a partial turn.
In carrying my Invention into effect I form the coupling socket as heretofore
to screw on to one of the parts to be connected together and when screwed
together sufficiently to obtain a firm connection I fix in one of such parts a pin or
stud to act in combination with suitable stops on the other of such parts, by this
means the said parts are so limited in their motion that they cannot become
unscrewed from each other and yet enough motion is allowed to enable the
packing between the ends of the connected parts to be sufficiently compressed; I
also form the aforesaid screws with comparatively quick threads.
The coupling piece is formed, on the face opposite to its screw, with an opening
of suitable form to receive similarly shaped wings or projections formed on one of
the articles or parts to be connected together. On placing the winged part end wise
in said opening and then turning the same and the coupling socket a partial turn

come under suitable flanges on the coupling socket and are prevented travelling too
far by suitable stops. The end of the winged part beyond the wings or projections
is formed cylindrical and to fit a cylindrical recess formed in the face or end of the
screwed part which recess also receives the leather or other packing ring placed
between the parts.
When the parts are adjusted in relation to each other as above described they
can be firmly coupled together by giving only a partial turn to one or other of the
screwed parts.

what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The invention has for its object improvements in unions or couplings for pipes
hose and other articles and relates to a novel construction of parts whereby great

When employing the ordinary screw coupling, several turns of the coupling piece
are necessary in order to effect a solid union of the parts and also to disconnect the

connected together. On placing the winged part endwise in said opening and then
turning the same and the coupling socket a partial turn in one direction in relation
to each other, the wings or projections are caused to come under suitable flanges on
the coupling socket and are prevented. travelling too far by suitable stops. The
end of the winged part beyond the wings or projections is formed cylindrical and
to fit a cylindrical recess formed in the face or end of the screwed part which recess
also receives the leather or other packing ring placed between the parts.
When the parts are adjusted in relation to each other as above described, they
can be firmly coupled together by giving only a partial turn to one or other of the
screwed parts.
And in order that my said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal section and Figure 2 is an outside view of two hose
connections coupled by means of my improved union or coupling.
Figure 3. is a side view of the part A Figures 4 and 5 are respectively a side
view and an end view of the part B. Figure 6 is a cross section drawn on the
line 1, 1, of Figure 2 and Figures 7 and 8 are respectively an end view and a cross

page_text: According to my invention I form the coupling socket C, as heretofore with an
internal thread c to screw on to the part A, which is formed with a screw thread a,
and when screwed together sufficiently. to obtain a firm connection, I fix in one of
such parts, preferably the part A, a pin or stud a¹ to act in combination with
suitable stops c¹ on the part C, by this means the said parts A and C are so limited
in their motion that they cannot become unscrewed from each other and yet
enough motion is allowed to enable the packing d between the ends of the
connected parts A, B, to be sufficiently compressed I also form the aforesaid
screws a. c. with comparatively quick threads.
The coupling piece C, is formed on the face opposite to that of its screw c with
an opening of suitable form to receive the end of part B, and the wings or
projections b formed thereon. On placing the winged part B endwise in said
opening c² and then turning the same and the coupling socket C, a partial turn in
one direction in relation to each other, the wings or projections 6 are caused to
come under suitable flanges c³ on the coupling socket C, and are prevented
travelling too far by a suitable stop c. The ends of the part B, beyond the
wings or projections b is formed cylindrical and to fit a cylindrical recess a² formed
in the end of the screwed part A which recess a* also receives the leather or other
packing ring d placed between the parts A. B.
When the parts A, B, C, are adjusted in relation to each other as above described
they can be firmly coupled together by giving only a partial turn to one or other
of the screwed parts.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
First Connecting together the parts A, B by means of a coupling piece C,
permanently screwed on to the screw a but capable of partial rotation thereon for
coupling and uncoupling the parts A, B, of pipes, hose or other articles sub-
stantially as herein shown and described.
Second: The improved union or coupling, for pipes, hose and other articles,
consisting of a coupling piece C permanently screwed on to the screw a and
securing the part B thereto by wings or projections 6 passing into openings c³ and
under flanges c³ substantially as herein shown and described.
Third: The improved construction of union or coupling consisting of a coupling
piece C, corresponding screws a c stops a¹ c¹ wings or projections b, openings c
flanges stop c cylindrical part 61 and corresponding recess a" and packing d all
substantially as herein shown and described and for the purpose stated.
