VACUUM-CLEANER HOSE-PIPE.

' messes.

To all whom it may concern Be it knownthat I, DANIEL B. Ramona, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, havein'vented a new and useful Vacuum-Cleaner Hose-Pipe, of which the following is a specification.

This invention relates to hose-pipes suitable for use in vacuum cleaning, and has.

for its objects, to render such hose-pipes a greater flexibility than heretofore attamed, to suitably attach fiber nipples to such hosepipes and render them more serviceable generally. V

To these ends the invention consists of the construction and arrangement. of parts set forth herein and-illustrated in the accompanying drawing in which p Figure 1 is a view of an end of hose pipe constructed according to my invention, the covering being partly removed to show interior construction.

Fig. 2 is a cross section showin the details of attachment of a fiber nipp e.

pervious to air by a coating'of, rubber .on" at least one of its sides; This fabric is preferably applied b cutting into strips, arranging plalts or olds 3 longitudinally thereof, then wrappin so that the exteriorly exposed gumme edge 4 is covered or lapped over by the interiorly. disposed '1) ed edge 5; thus making a continuous sealed joint helical1y' wound about the wire frame 1.

A stron soft braiding 6 is then ap lied coveringt e fabric 2, and a fine fims g brai 7 is appliedias an outside cover; e of fiber or similar mate- A nipp e 8 ma rial must be attached before the hose is usable. This is done by these particular means. riorly screw-threaded opposite y to the spiml of the wire frame 1. The end 9 is then Specification of Letters Patent.

process may require several hours. of time.

In pract1ce', l procure what is commercially known as vulcanized fiber tubing made from cotton rags. The kinds made from wood pulp are not so strong and reliable The thickness of the wall of the tubing should be in the neighborhood of threeto five per cent. of the entire diameter of the tube, so that the circumferential expansion, when soaked, will be a fair approach to the thickness of the wall.

This tubing is "sawed into lengths as desired, or it may be cut on a lathe, so thatnurlin v of the outside surface, as well as threading of the interior,'may be performed wlth once handling. The pieces are now ready for expansion, which may be efiected by settmg them in shallow water to a depth required to soak the threaded end to a little beyond the threaded portion. When the portlon soaked has become soft. and pliable, it is ready to be attached.

A ferrule 11 is now inserted into the end of a cut 0E piece of hose body so that it will .116 against and support the wire frame from -0II1Sh1ng 1n by outside pressure. A rim 12 of said ferrule 11 will cover the cut ends of braiding threads and projections or cars 13 hook between coils of wire to anchor the same firmly into the end of the cut off hose body. After this is placed the expanded end 9. 0f nipple 8, with or wlthout cement applied, 1s screwed over the braidings compressing them closely against the wire coil Y 1, which screwing action tends to reduce the diameter 'of the coil and drive it firmly against the curved surface of the ferrule 11.

Any attempt to unscrew same, as is aparent, will tend to increase diameter of the C011 and mcrease the anchoring effect. As the nipple end dries and contracts to normal diameter, it is still more 1 tightly drawn,

compressing the fabric and raidmgs so expanded by or soaking, which tightly as to make an air proof 'oint as well as permanently securing said mpple to the hose body end.

When using the hose, of course both ends are secured into a nipple as explained especially when the same is to be applied to a movable vacuum cleaner. Hose thus con- 'structed has not only a very flexible but an extensible and contractible body so that it is easily manipulated when vacuum cleaner tools are used in connection with it. Details of construction may be varied without departing from my invention.

What I claim by patent is: 1. In a flexible hose, an interior rigid coil,

a rubber coated fabric with edges sealed,

covering aid coil, braidingscovering said fabric, a ferrule, having ears hookin into. said coil and bracing the interior of said coil and a nipple having a contracting end threaded oppositely to. said coil and secured over-the end of coil, fabric and braiding, compressing same against the said ferrule.

2. In a flexible hose having skeleton wire coil body with fabric and braiding covering the same, a nipple havin an expansible interior threaded end, said end being contracted over the end of the body of the hose, the threads of said end spiralingoppositely to said wire coil.

3. In a flexible hose, a wire coil skeleton, a gummed fabric and a braiding covering the same, an interior ferrule secured to an end of said coil, and a threaded nipple made of hygrometric material having an expansible end contracted over the end of said coil and clasping the coverings-and coil aforesaid against the ferrule 1n the interior of the coil.

4. In a flexible hose, a wire coil skeleton,

a suitable air tight fabric coverin said coil,

1 tracted over said end.

5. In a flexible hose end, a coiled wire skeleton, an interior supporting ferrule, an exterior air tight fabric covering; and a 40 .nipple made of hygrometric material, contracted over said end.

6'. In a flexible hose end, a coiled wire skeleton, an interior supporting ferrule, an exterior. air tight fabric covering and a 4 nipple made of hygrometric mater1al,having an end internally threaded oppositely to the coils of said wire, contracted on said end.

' 7 A flexible hose comprising a skeleton coil, an air-proofed pliable fabric covering said coil, and a nipple of hygrometric material contracted on an end thereof.

8. A vacuum cleaner hose comprising an interior non-collapsing coil, an alr-proofed pliable fabric covering the same, an end nipple of hygrometric material contracted on an end thereof and means for supporting the interior coil against the contraction of said nipple.
