IMPRQVEMET IN HOSE AND PIPH-COUPLING-B.

The Schedule referred. to in these Lettera Patent and melting part of the uma.

To all whom it may concern Be it known that I, J. O. THOMPSON, of Charlestown, in the county of Middlesex, and State of Massachusetts, have invented an Improvement in Securing Hose to Couplings; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description. of my invention, suiicient to enable those skilled in the ait to practise it. 1

Hose are often and commonly united to the neckpieces of hose-couplings, especially the smaller kinds of hose known as hand-hose, and used'for washing buildings, windows, sidewalks, 850., by winding their ends upon the coupling-necks with wire, preferably of correu This operation consumes some time, and the wire is very liable to break, .by' reason of the tensile strain put up'on it, which strain is necessary to secure the hose upon the coupling-necks water-tight, 'and so as to prevent the coupling-necks from drawing out ofthe hose in actual use..

Moreover, the ends of the wire are apt to project and cut and scratch the-.hands and oorsor other surfaces over which the hose are drawn in use.

My invention dispenses with .the use of bindingwire; and i lIt consists in making use of a ring or ferrnle upon the hose in the following marinier:

A thin metallic ring o'r ferrule, the width-of which approximates about one-third of its diameter, is placed over the end of the hose t0 be united to a couplingneck, the outer diameter of the ring being about equal to or slightly less than the outer diameter of the hose. This compresses the hose, as seen in Figure 1, which is a central longitudinal section through the end of a piece of bose, as it appears after,Y the ferrule or ling isy applied thereto. Then the hose is placed in a vise or clamp, leaving its end projecting beyond the distance which the coupling-neck is to ll therein.

Figure 2 is a view, partly in elevation and partly in longitudinal central section, showing the end of a piece of' hose united to the neck of one part 'of the screw-coupling.

a is the hose;

l), the ferrule or ring thereon;

c, the coupling-neck; and

d, the nut-part of the coupling.

When the hose-end is secured in a vise or clamp, as stated, its inside surface is coated with rubber cement, and thel outer grooved or 'ribbed surface of the coupling-neck c is also coated with rubber cement, and the end of c being entered in the open'mout-h of the hose, is driven home therein by a quick, powerful movement, expanding and stretching the material of' the hose, and pinching it between the inner' surface oi' ring band the outer surface of c, to an extent which sui'ices to make a joint' water or steam-tight under all pressures which the hose will bear, and whichy will eectually resist any strain -likely to be exerted in practical use, tending to draw the coupling-neck out of the hose-end.

The use of the ring or ferrule-b, as described, is especially adapted for rubber hose, though it may be applied to.hose of other yielding material.

Other c ementitious matter than rubber cement may be used, or cement may be omitted, though the best results are pbtained by employment of cement.

The cement acts as a lubricant to facilitate entrance ofthe coupling-neck, and when Icement; is not used,

y the inside'of the bose Or the outsidev of the. couplingneck, or both, may be simply moistened -or wet, to facilitate the entrance of the coupling-neck.

I` claim the combination of the hose a with the coupling-neck c, by means of the ring b, applied and operating substantially as described.
