IMPROVEMENTS IN HOSE COUPLINGS
Year: 1884

page_text: I JAMES CADOUX HUDSON, of 75 Upper Ground Street, Blackfriars, in the
County of Surrey, "Engineer," do hereby declare the nature of my Invention for
"IMPROVEMENTS IN HOSE COUPLINGS," to be as follows:-
This invention' relates to improvements in Hose Couplings, more especially those
in which a flexible washer or ring of rubber or other material is used to make the
joint between the male and female parts of the Coupling, and is for the purpose of
better securing the washer in the recess in Coupling in which it is carried. I insert
a collar or bush, split or otherwise, into a recess or enlargement of the bore of
Coupling formed in that part of Coupling which carries the rubber washer. This
bush has a certain motion in the direction of the axis of the bore of Coupling.
When the bush is forced back into its recess, the groove carrying the rubber washer
is fully exposed and the washer can be inserted or withdrawn, but when the washer
has been inserted, the bush can be drawn forward and closes up that side of groove
toward the bore of coupling firmly fixing the washer and preventing it being
accidentally displaced. The bush when split can be formed out of tube of larger
external diameter than the recess into which it fits, a piece being cut out gives a
certain amount of spring which is beneficial in holding it in position. The enlarge-
ment of bore or recess for split collar can be formed with a taper part or slight
collar to give additional firmness to the collar when placed for securing the rubber
washer. The collar can be split by a cut in the direction of its axis or diagonally
to it;

DIECIFICATION.
I JAMES CADOUX HUDSON of 75 Upper Ground Street Blackfriars Rd in the
County of Surrey, Engineer, do hereby declare the nature of my Invention for
IMPROVEMENTS IN HOSE COUPLINGS 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 improvements in Hose Couplings more especially those
in which a flexible washer or ring of rubber or other material is used to make the
joint between the male and female parts of the coupling and is for the purpose of
better securing the washer in the recess in coupling in which it is carried. I insert
a collar or bush split or otherwise into a recess or enlargement of the bore of
coupling formed in that part of coupling which carries the rubber washer. This
bush has a certain motion in the direction of the axis of the bore of coupling,
When the bush is forced back into its recess the groove carrying the washer is fully
exposed and the washer can be inserted or withdrawn, but when the washer has
been inserted the bush can be drawn forward and closes up that side of groove
towards the bore of coupling firmly fixing the washer and preventing it being
accidentally displaced. The bush when split can be formed out of tube of larger
external diameter than the recess into which it fits, a piece being cut out gives a
certain amount of spring which is beneficial in holding it in position The enlarge-
ment of bore or recess for split collar can be formed with a taper part or slight
collar to give additional firmness to the collar when placed for securing the rubber
washer. The collar can be split by a cut in the direction of its axis or diagonally
to it.
In order that my said Invention may be most fully understood and readily carried
into effect I will proceed to describe the Drawing hereunto annexed.
Figure 1 is a longitudinal section of a coupling made according to my Invention
Patent No 3133 June 23rd 1883 and shews the improved collar or bush A in position
for better securing the rubber washer B. When the bush is forced back into the
recess C. as shewn in dotted lines, the groove D. for carrying the rubber washer is
fully exposed and the washer B can be inserted or withdrawn. But when the
washer B has been inserted the collar or bush A can be drawn forward, as shown
on drawing and closes that; side of groove towards bore of coupling firmly fixing
the washer B and preventing it being accidentally displaced. The enlargement of
bore or recess for split collar can be formed with a taper part or small collar E
to give additional firmness to the collar when placed for securing the rubber
washer B.
Figure 2 is an end elevation of the same coupling.
Figure 3 is a section of the split collar or bush A.
Figure 4 is a plan of same shewing the collar split by a cut in the direction of
its axis or it can be split by a cut diagonally to it.

page_text: 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. The arrangement of a split collar or bush as before described for preventing
the rubber washer being accidentally displaced, and for the better means of securing
the same.
