HOSE- BAND.

SPECIFICATION formingpart `of Letters Patent No. 224,586, dated February 17, 1880. I

Application filed December 8, 1879. i

To all whom it may concern Be it known that I, OSCAR T. EARLE, of Milford, inthe county of New Haven, and in the State of Connecticut, have invented an Im- 5 provement in Hose-Bandmof which the following is a specitication.

This invention relates to an improvement in hose-bands and a method of applying the `same, and is substantially developed from the improved hose-band invented by me and patented, No. 172,982.

. In the drawings, Figure 1 represents a hosel" coupling with ahose upon it and the band in sight in exterior view. Fig. 2 isla cross-scction at the line a' of Fig. l. Fig. 3 is alon- `gitudinal section at the line x of Fig. 1. Fig. his a similar cross-section of a slightly-modified-form of thecontrivance. Fig. 5 is a similar longitudinal section ot' fsuch modified` form and Figs. 6 and Tshow means forcompressing, iitting,.and applying the hose-bands to the hose, 85e.

Like letters indicate like `parts in all the g- `A is the coupling, formed in the usual manner, of metal, and properly prepared on its eX- put `around. the hose ahinged collar or a pair of half-collars provided with ears, through which is inserteda bolt, by which the sides of the collar are `drawn together and compress "the lexible hose upon the coupling.

The improvement which I originally made .ein hose-bands was well adapted to small hose. .i 4o

and was also serviceable for the larger kind of hose but the present improvement is one that is somewhat :more economical oi' material, inasmuch as a heavy clasp may be combined with a light strap, and is also more easily made and is quite aseasily applied.

C is the burr, and-Dis the strap. A hook is formed on one end of the strap D,` and is Y hooked into one sideof the burr C, its free end being so adjusted as to `-lie next the hose 5o B at a point about the middle of the neck of the coupling, which should be made in the B is the..

and tightly drawn up, so as to embed itselt' in the hose and compress the, hose firmly upon the neck of the coupling. `As I have said, it is best to make the burr of thicker metal than the strap.

I have described this contrivance as employing a burr and a sti-api of sheet metal but it is obvious round wires may be used in lieu of flat metal, and Figs. 4 and 5 represent (D) the use of round wires, either singly or in gangs, in connection with this burrI have described. The burr is a piece of' metal with a suitablyshaped hole pierced in it to receive the band. It'. the band is of round wires, this hole may be formed eitherround or'oval, so as to give a considerably transverse bearin g to the wires, or it may be formed oblong and a gang of wires used. i i

Although the burr and band of this apparatus bear a certain' resemblance to a cottonbale tie, yet when the nature ot' the operation of this apparatus is compared with the nature of the operation of the cotton-bale tie it will be seen that there is afundamental difference between them. i i

A cotton-bale or any other bale of goods is compressible throughout its bulk, and in the application ofthe ties they are put onto the bale somewhat slack, when that is compressed by machinery beyond the bulk which it assumes when banded and released from the press, so that the tightening of the bands is due to the elasticity of the compressed material.

In the case of'a hose we have a non-compressible core with a compressible exterior, which we wish to bind to the non-compressible core, in order that it may so closely cling to the core as not to slide upon it longitudinally. In order to do this it is necessary that the strain should` be applied over the place of the band, and that the band itself should be'positively forced into its compressing position. In Aorder to do this it is desirable to have a tool composed of `a flexible strap or chain adapted to surround the coupling over the place of the band and to be drawn together by a screw or other power, so as to shorten the lil band by actual pressure upon its exterior surface and embed it in the compressible material of the hose itself, thereby bringing it into close contact with the neck of the coupling, and thus allowing the band to be drawn through and turned back over the burr.

It will be seen, therefore, that, while in a bale-tie both ends of the strap are turned under and moused by the expansion of the compressed material in this band, there is no opportunity to turn in the free end for the purpose of mousing it, and reliance must be had upon the tensile strength of the metal and its stiffness at the point where it turns over the burr. trated in Fig. 6 of the drawings, and in Fig. 7, which is a cross-section in line x x of Fig. 1, showing the manner in which a chain-coinpressor operates to fit the band to its place.

F isa yoke, having attached to it at one end a exible chain or strap, G, which chain G is provided withabutments, in this case consisting of the flexible rolls h of an ordinary lathe-chain. At the other end of this yoke F is pivoted a nut, I, through which works the hand-screw K, carrying on its end a swiveled jaw, L, to take hold of the abutmentsreferred to in the flexible strap. l Y

The way this lnechanism works to apply one of the bands referred to is as follows: The-hose being slipped upon the coupling, a burr having a strap attached to it is put round in its proper place and the free end of the strap passed through the burr upward. This apparatus is taken and the flexible band G put round the hose, andthe abutment h is engaged with the jaw K. The burr should be adjusted so as to come at the place of the yoke, the end of the yoke to which the chain is fastened being placed over the edges of the burr. Upon tightening the screw it will be seen that the burr is itself drawn down upon the hose. The band D is then compressed by the chain, or its equivalent, into and upon the hose throughout the entire circumference of the hose, and will thus be shortened by the traverse of the chain over it, and will be forced up at its free end through the burr. When a suicient amount has been protruded through the burr the free end is turned down and clinched by hammer or otherwise, and, the screw being loosened, it will be found that the hose is tightly banded to the coupling. By this apparatus referred to a sufficient strain can be brought to bear upon the exterior of the hose in the place of the band to crush the neck of the coupling itself, and consequently it is very An apparatus for this purpose is illusevident that it is easy, with this simple tool, to repair, with these bands, a large piece of hose which may happen to burst, on occasion,

vbe readily applied by described apparatus to any compressible covering for anon-compressible core.

I have described a tool herein for applying the band to the hose in a peculiar manner, and in an application for Letters Patent now pending I have separately claimed the same. I do not intend to conine myself, however, to this particular mechanism for applying the band; yet I prefer one that shall operate in principle to compress the band upon the hose as herein set forth, although other means may be employed.

It will be seen that this tool differs materially from the tools described in my former patent, and is applicable to bands which have no projections for the engagement of the jaws in order to draw the band tightly upon the hose, and that by the aid of this tool a much greater range of sizes can be applied with one instrument, and also that the compression of the band upon the hose and with its substance is much more uniform, and does not depend at all upon the stretch of the material of the band, nor is it interfered with by the application of the band upon the surface of the hose.

I therefore claim as my invention- 1. The'combination, witha non-compressible core surrounded by a comprcssible casing, of a burr, G, in combination with a flexible metallic band, D, compressed and drawn upon the exterior of the compressible envelope by means exterior to itself, substantially as described.

2. In combination with a compressible body, the burr C and band D, surrounding the same and tightly drawn upon and compressed into the same by a positively-actuated flexible band applied over the said band D and tightly drawn upon it, whereby said band D is shortened to its holding position, substantially-as described.
