PROVISIONAL SPECIFICATION.
An Improved Device for Uniting Rubber Hose and the like to Nozzles
or other Objects.
I, JOHN THOMAS DUNCAN, Student, 105, Chesterton Road, Notting Hill, London,
England, do hereby declare the nature of this invention to be as follows:-
The invention consists essentially of a powerful spring of steel or other suitable
material in the form approximately of a portion of a circle . This may be of
diameter suitable, and indented or shaped so as to firmly hold objects together.
In length it may be such as best to accomplish its purpose. At each edge of this
spring may be one or more openings, into which levers may be inserted, which
levers may be of any shape whereby the said springs may be best opened.

An Improved Device for Uniting Rubber Hose and the like to Nozzles
or other Objects.
I, JOHN THOMAS DUNCAN, Student, 105, Chesterton Road, Notting Hill, London,
England, 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 invention consists essentially of a powerful spring of steel or other suitable
material in the form approximately of a portion of a circle, which may be a plain
band, or formed with indentations or heads or so shaped as to firmly hold objects
together; and of a diameter suitable. In length it may be such as best to accom-
plish its purpose.
At each edge of this spring may be one or more openings into
which levers may be inserted, which levers may be of any shape whereby the said
springs may be opened.
Reference is to be had to the accompanying drawings, forming part of this
specification, in which similar characters of reference indicate corresponding
parts in all the figures.
Fgure 1 is a perspective view of the improvement.-Fig. 2 is a cross section
of the same in an opened up position by the use of specially formed levers, and

page_text: Fig. 3 is a longitudinal section of the improvement as applied on the hose
and nozzle.
The improved hose spring may be made in the form of a split tubular spring
ban A (containing indentations A¹) of steel or other suitable material, to permit
of forcibly opening the ends of the band for applying it on the hose B, to secure
the end thereof on a nozzle C, coupling, plug, or other device.
The levers D being entered by their tips into the openings A2 the handle ends
of the levers are pressed together, thus forcing the tips D¹ apart, thus opening up
the band A which is then carried upon the hose. After this is done the operator
releases the pressure of the levers, so that the resiliency of the band A will again
cause it to close and press the flexible material of the hose into the indentations,
or against the corrugations on the shank C¹ of the nozzle C when the levers are
removed.
It will be seen that, by the arrangement described the hose, or other material is
securely fastened to the nozzle, plug or other device without requiring much skill
on the part of the operator.
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. As a new article of manufacture, a hose spring consisting of a steel band (or
other suitable material) approximately in the form of a portion of a circle, which
may be opened up and sprung upon the hose or other like material, and which,
by its own resiliency, will press upon the said flexible material, thus forcing it
against the corrugations or into the indentations of the device to which it is
attached, substantially as shown and described:
