Abstract

Two lengths of hose or pipe can be connected by securing them between two halves of a hollow threaded tapered tube, and held down with one or more nuts secured over the taper. Typically, a tubular insert within the ends of hose is also clamped into place, so that the hose ends are securely held between the insert and the tapered tube. <IMAGE>

Description

SPECIFICATION Plastic hose fastener This invention relates to the installation of original equipment or replacement of damaged hose.

Hose are made mainly synthetically, viz; Rubber, Casein, Cellulose etc., This invention, manufactured from certain synthetics, can be used with complete confidence.

It is impervious to Rust-erosion, Acids, Oil, Petrol, Detergents.

Present means of securing hoses give cause for grave concern for safety, both to personal injury and damage to surrounding surfaces.

When evaluating the merits of this invention, the personal safety factor should be of tantamount importance.

With some existing "Hose clips", one must use a screwdriver.

This "Hose Fastener" eliminates the use of a screwdriver, thereby nullifying the personal injury factor and the "Knurled plastic nut", fits snugly in either hand, whilst either tightening or releasing.

The Hose Fastener may be used many times without losing its efficiency.

The component consists of two halves of a tube. The inside Diameter is relative to the hose it must enclose. With a tapered thread .020 (say twelve threads to one inch) on the outside, two thirds of its length, and a knurled nut, one third of the length of the said tube.

Different colours could be incorporated at source of manufacture, ensuring the appropriate size to be used.

Immediate release is another obvious advantage, when a repair is necessary.

Generally, the Hose Fastener would be associated with vehicle engine repair and their auxiliaries.

Servicing of hose transporting liquids from one point to another, e.g., Garden hose.

The obvious advantage of this Hose Fastener when compared with present day available hose clips.

1. Inexpensive to Manufacture.

2. Impervious to Rust, Acid, Oil, Petrol etc., 3. No Tools required to fit or replace.

4. Elimination of injury to self or surrounding work surface.

5. May be used repeatedly.

6. Quick release, no rusting up.

7. Labour and Cost saving.

8. Colours-These are relative to the specific sizes.

1. A hose fastener comprising a body formed in two parts so that they can be placed together to enclose a length of hose and opened up to enable the length of hose to be withdrawn or inserted, the body in its closed configuration defining an open tube within which the hose length can be securely held, the outer surface of the body comprising a tapered surface provided with a screw thread, a nut being provided to fit over the screw thread to secure the two parts of the body together.

2. A hose fastener as claimed in claim 1, wherein there are two said tapered surfaces, one directed towards each end of the body, and two corresponding said nuts.

3. A hose fastener as claimed in claim 1 or 2, wherein the body is a single piece, comprising a flexible hinge line connecting the two parts together.

4. A hose fastener as claimed in claim 1, 2 or 3, wherein the or each screw thread is a buttress thread.

5. A hose fastener as claimed in any preceding claim, in combination with a tubular insert arranged to be located substantially wholly within the said body in its closed configuration, and adapted to be inserted within the end of the or each length of hose held within the body.

6. A hose fastener as claimed in claim 5, wherein the tubular insert comprises a transverse flange intermediate the ends of the tube.

7. A hose fastener as claimed in claim 5 or 6, wherein the tubular insert comprises a plurality of circumferential ridges spaced along its length.

8. A hose fastener as claimed in claim 7, further comprising a plurality of recesses within the inner surface of the body, corresponding to the ridges on the tubular insert.

9. A hose fastener, substantially as herein described with reference to any of the accompanying drawings.

10. A method of securing two ends of tube together, the method comprising the steps of placing the ends into the hollow of a concave body part, placing a second body part over the first so that the two body parts define an open tube with the two ends of tube held within it, the outer surface of the tube formed by the two body parts being slightly tapered and provided with a screw thread, and securing a nut over the tapered surface to secure the two parts slightly together, whereby clamping the two ends of tube together.

11. A method as claimed in claim 10, further comprising the step of securing a second nut over a second tapered surface, so that each said nut is located firmly over a respective one of the two ends of tube.

12. A method as claimed in claim 10 or 11, further comprising the step of placing each of the two ends of tube over a tubular insert to link them together.

13. A method as claimed in claim 12, wherein the or each nut is secured over a portion of the hose ends within which the

**WARNING** end of DESC field may overlap start of CLMS **.
