A DUPLICATE CLUTCH UNION FOR HOSE AND OTHER JOINTS
Year: 1884

page_text: ARTHUR GODMAN St Stephens St Albans Herts, Engineer, do hereby declare the
nature of my invention for A DUPLICATE CLUTCH UNION FOR HOSE AND OTHER
JOINTS, to be as follows:-
The halves are drawn together by two or more wedge shaped clutches, in
segments on the outside of each half of Union.
One, or each half has one or more India-rubber or other elastic rings, or washers
fitted into annular recesses, at joint end behind the Clutches.
The clutches may be shrouded to the lugs, or to other parts of Union.
One, or each half can have a swivel carrying the Clutches &
Any two halves either with or without elastic rings, or washers, or swivel, or
shrouding, will connect together.
To make the connection place the Clutches of one half between the clutches of
the other half, and give it part of a turn.

page_text: I ARTHUR GODMAN of Saint Stephen's Saint Albans in the County of Hertford
Engineer, do hereby declare the nature of my invention for A DUPLICATE CLUTCH
UNION FOR HOSE AND OTHER JOINTS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
These Improvements relate to unions for connecting lengths of hose and for
other similar purposes and have for their object to enable the different lengths or
parts of the hose to be coupled or uncoupled without the use of springs or screws.
And in order that my Invention may be more readily understood and carried
into practical effect I have hereunto appended a sheet of drawings marked with
letters of reference similar letters denoting similar parts in the various figures.
Fig 1 is a plan of a union constructed according to this Invention portions of
two lengths of hose e e being also shown attached thereto.
Fig 2 is an end view of one portion or half of the complete union. Fig 3 is a
longitudinal section through A. B. Fig 2. Fig 4 is an end view of a modification
of the union and Fig 5 is a longitudinal section through C. D Fig 4.
The two halves or portions h. of the union are made similar to each other and
have clutches cast upon or secured thereto in such a manner that the clutches of
one half are capable of engaging with the clutches upon the other half by a part
turn of one or both portions of the union and thereby bringing the two halves into
firm and rigid connection with each other. When it is considered advisable to do
so india-rubber, leather or other washers may be employed with the unions as
hereinafter described. The use of such washers may be desirable for example when
heavy pressures of fluid have to be borne by the apparatus or when the presence of
grit or dirt might be likely to prevent the perfect metal to metal contact of the
two parts of the union.
The clutches a a¹ all project laterally from the side of the upper part of each
half of the union and consist of the tongues or projections a and the pockets or
recesses a within the part a. The number of the clutches may be two as shown
in Figs 1. 2. 3. and 6 or three as shown in Figs 4 and 5 but in couplings of large
dimensions any convenient number of, clutches may be employed. The under
surface of the tongues a is slightly inclined upwards and outwards towards the
point so that when the two parts of the union are brought together and rotated
through a small arc a screw action will result and the two parts be brought firmly
into contact with each other. The two parts of the union being precisely alike
they are more convenient to couple up than when a male and female pair havo to
be employed as either end of a length of hose fitted with the union herein described
may be connected to either end of another length by merely dropping the clutches
of one part of the union into the spaces between the clutches of the other, and
giving part of a turn so as to cause the tongues a of one set of clutches to
engage in the recesses all of the other set. The union may be uncoupled by
reversing the operation.
When it is desired to employ india-rubber, leather, or other washers these may
be inserted in grooves turned upon the ends of the union as shown at cc in
Figs 2. 3 5 and 6.
When it is deemed necessary to provide for twisting of the hose the clutches
may be formed upon a ring fitting upon and surrounding the half union in which
case a collar may be formed upon the contact end of the half union as shown in

page_text: Fig 6 or other equivalent arrangement be adopted to receive the pull originated
in making connection and thus cause the two halves to be firmly connected with
each other.
The lugs or trunnions g g may be attached to the clutches as shown or they may
occupy any other convenient position or be dispensed with altogether.
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:-
(1) In unions employed for connecting lengths of hose and for similar purposes
the use of two similar halves or parts capable of engaging with each other by
means of the clutches a al a." substantially as hereinbefore set forth and described
and as illustrated on the accompanying sheet of Drawings.
(2) In unions employed for connecting lengths of hose and for similar purposes
the use of clutches consisting of the tongue a and the recess or pocket all
substantially as hereinbefore set forth and described and as illustrated on the
accompanying sheet of Drawings.
Dated this Second day of January 1885.
