Abstract

A hose clip is provided in three separate parts: a screw 16, a housing 11 arranged so that the screw can fit completely within it, and a strip 13 of reasonably soft material, which may be cut off to length from a roll to suit the size of hose to be coupled. An indent is formed in an end of the strip for engagement with an abutment on the housing. The screw may be provided with a buttress thread so that it can form its own "thread" in the strip. Instead of a multitude of different-sized hose clips, all that is required to provide hoseclips in a workshop is a single supply of screws, a single supply of housings, and a roll of strip that can be cut to a length suitable for passing around the particular hose, and indented as required. <IMAGE>

Description

SPECIFICATION Metal hose clip This invention relates to hoses, plastic or otherwise and the securing thereof.

Hoses of all descriptions are universally used throughout the World for purposes that we cannot fully comprehend. We have not improved the Hose-clip by design or capability for the last 50 years and without such a component we could not manage International Industry.

Hoses mainly consist of synthetics, such as rubber, casein, cellulose etc., and these are all pliable.

When a hose-clip is used, the ultimate aim is a leakproof joint between hose tube or pipe. This is currently accomplished by screwing an "Acme threaded wormed screw" through a saddle which has a circular strip of metal passing through (this strip has been indented to match the wormed screw) and as the screw is turned, it automatically picks up the thread in the strip, thus closing the strip against the outside of the soft hose and crushing it into any gaps between the tube or pipe, assuring a leakproof joint.

This in my opinion, (I am a Toolmaker,) is antiquated, expensive and inefficient. When a present day hose-clip is to be replaced, it is either attributable to corrosion (dirt, dust, grit) or erosion (acid, rust). Paramount importance is the personal safety factor, many Fitters have suffered injury when unscrewing wormdrives, or slipped whilst endeavouring to release a hose clip that has become solid with either rust or dirt. Damaging paintwork of a vehicle on the final assembly line is another problem, resulting from this factor. The Hose-clip I now submit for your deliberations, will I feel sure, eliminate most of the faults of the Hose-clips that are at present on the market.

First the composition. It consists of three components.

1. A strip of low carbon steel indented one side only to represent a screwed thread. One end rounded off, the other indented in the centre of the strips width, to the thickness of guage being used.

(Drawings self explanatory). As the buttress screw is self-threading plain strip could be used.

2. Housing, formed by press tools, with slot to accommodate above strip, 1/ to pass through and locate on base of housing, with centre of width indent. (see drawing for explicit detail).

3. Screw with tapered Buttress Thread Tempered Good screwdriver slot essential twice as deep as normal. This screw must recess below the aperture of the housing at least twice the depth of screwdriver slot. (See drawing for explicit detail).

When fitting a new or used hose-clip of my invention, the procedings are quite simple.

1. Take a strip of metal (1) with all the indents on, or plain fold around hose the clip is to fit.

2. Hold housing so that (1) the strip can be inserted in the slot at the rear of the housing. Let the indent in the centre of the strip rest on the base of the housing at This will stop any moving about. Slip the looped strip (1) over the hose and insert over the top of the other end of the strips through the slot at the base of the housing. You now have the housing on top of the hose with the two ends in the housing.

The top part of the strip should be protuding towards the aperture, where the screw locates, and the other end of the strip, with the extra deep insert underneath. These two ends of the strip will be somewhat flexible. Press them down, with the tapered thread end of the buttress screw and using screwdriver, proceed to tighten.

You will immediately locate into the indented strip and start to tighten and as this happens the buttress screw moves forward to the backplate of the housing. This is as far as the screw can travel, the slot in the screw is so deeply shrouded by the housing, it is impossible to slip. Use as much "twist" on the screwdriver as is necessary to complete a sound, safe, economical fitting.

1. A hose clip comprising a housing open at one end and providing an abutment at an opposite end thereof, a screw arranged to fit substantially wholly within the housing with the screw head towards said open end, and a strip adapted to pass through the end of the housing and around a hose, the strip being provided with an abutment adapted to abut said abutment of the housing.

2. A hose clip as claimed in claim 1, wherein the abutment of the strip comprises an indent formed therein.

3. A hose clip as claimed in claim 1 or 2, wherein the housing is formed of a sheet pressed to provide the sides and end of the housing.

4. A hose clip as claimed in claim 1, 2 or 3, wherein the strip is formed of a low carbon steel.

5. A hose clip as claimed in any preceding claim, wherein the strip is arcuate in cross-section.

6. A hose clip as claimed in any preceding claim, wherein the screw is provided with a buttress thread.

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

8. A method of securing a hose to a tube, the method comprising the steps of positioning a strip against the hose, the strip being provided with an abutment at or adjacent and end thereof, fitting a housing which is open at one end and partly closed at an opposite end thereof over the strip so that an end of the housing rests against said abutment, passing the other end of the strip around the hose, where it is fitted over the tube, and through the housing, positioning a screw substantially wholly within the housing with the screw head facing out towards the open end of the housing so that the screw threads engage the strip, and turning the screw to pull the strip tight around the hose.

9. A method as claimed in claim 8, further comprising the step of cutting the strip from a stock of continuous strip.

10. A method of securing a hose to a tube, sub
