PROVISIONAL SPECIFICATION.
An Improved Clamp.
I PHILIP JONES of Inglewood, in the Colony of Victoria, Coachbuilder, do
hereby declare the nature of this invention to be as follows:-
A clamp according to this invention consists of a band of metal turned into a
ring and having the free ends turned over the ring part and attached to a firm
support fitted with a thumb screw which by screwing down contracts the diameter
of the ring part by forcing up the firmn part. Such a clamping device is particu-
larly suitable for connecting the end of a hose to a pipe, or for joining hose
together, in the latter case two clamps are preferred to be used. The clamp is
also suitable for use in connection with attaching various parts temporarily to
cycles and for other purposes; the firm part being fitted for attaching an arm or
guideway to.

COMPLETE
SPECIFICATION.
An Improved Clamp.
I, PHILIP JONES, of Inglewood, in the Colony of Victoria, Coachbuilder, 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 :-
My invention consists of an improved clamp for fastening hose to taps, or for
connecting two sections of hose together, in the latter case two of my clamps being
generally used. My clamp is so made that it consists of two parts only viz., a two
turn ring and a ring-contracting screw, and by means of the latter the ring when
placed over a hose which is to be clamped down to a tap or pipe can be contracted
to the required diameter and be made to hold with enormous force. In consequence
then of this simplicity of construction my clamp is extremely cheap to make and
convenient to use. Moreover whilst this clamp is of thin steel and therefore very
light it offers a large gripping surface which can be increased or diminished without
affecting the principle of construction.
Referring now to the accompanying drawings
--
Fig. 1 shows an end elevation of one of my clamps :
Fig. 2 shows a perspective view of the clamp as it appears when compressing
hose shown by A.
Fig. 3 is a view of the regulating or clamping screw B;
Figs. 4 and 5 show respectively a plan and side elevation of the flat blank which,
when curved, is used to form that portion marked C of the two turn ring which
contains the worm carrying the screw;
•
Figs. 6 and 7 show respectively a plan and side elevation of a flat blank or strip
of thin flexible steel, which, wheu curved, is used to form that portion marked D
of the two turn ring which is contractible on to, and is adapted to clamp, the hose.
LD OUT

page_text: Fig 8 shows in side elevation a tap having a hose secured thereto by means of
my clamp; and
Fig. 9 shows two separate hoses each clamped over a short rigid pipe E so as to
produce a coupling.
In all the figures like parts are indicated by the same letters of reference.
The blank having been prepared for the reception of the screw B is curved
into the form indicated in the drawing Fig. 1, and the two ends of D are then
riveted or otherwise permanently fixed to the ends of C so as to make a two turn
ring as shown in Fig. 1, that is, with one ring lying partly within the other and
being nearly as large. When the screw is turned downwards it presses against
the broad part of the inner ring and by such compression reduces the size of the
inner ring and enlarges the size of the outer ring. It will thus be seen how, by
the mere turning of the screw B, a hose as A may be firmly clamped down or may
be released at will without injury to either hose or tap, and without requiring any
fixtures or any but a plain cylindrical end to the hose or the tap.
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. A hose clamp consisting of a double ring and a binding screw arranged
substantially as herein described and as illustrated in the drawings.
2. In a hose clamp a double ring as described, so arranged that the size of the
clamping or inner ring can be varied at will the outer ring being caused to
enlarge as the inner is diminished and vice versa, substantially as set forth.
