1. In a combined hose joint and mount,for joining an end of a length of hose to another conduit means and mounting that end of the length of hose to a mounting fixture which includes a plate having an opening provided therethrough, this opening having a generally rounded bounding peripheral surface provided with two substantially angularly spaced, angularly short segments of substantially different radial extent than that of the remainder of said generally rounded peripheral surface, this plate being generally planar, but being bulged in one direction about an axis which extends generally parallel to a face of the plate in such a manner that both of said two substantially angularly spaced, angularly short segments of said peripheral surface of said opening are substantially axially displaced from the plane of the remainder of said plate, in which the combined hose joint and mount includes:

  • a tubular member adapted to be mounted to a length of hose in surrounding relation to an axially short region at an end of the length of hose, in order to permit the length of hose, at that region, to be mounted to another structure;

    a first radially outwardly projecting flange integrally provided on said tubular member;

    a second radially projecting flange fixed on said tubular member axially adjacent said first flange; and

    a third radially projecting flange fixed on said tubular member with axial spacing from said second flange so as to define between said second and third flanges a radially outwardly opening groove adapted to received a spring clip;

    said first radially outwardly projecting flange being defined in part by generally rounded, radially outer peripheral surface means, these radially outer peripheral surface means including at two substantially angularly spaced sites respective angularly short segments of substantially different radial extent than that of the remainder of said outer peripheral surface means;

    said first flange, including said two angularly short segments thereof, being sized and shaped to coact with said mounting fixture, as follows;

    if the tubular member is inserted, third flange first, into a said opening of a said mounting fixture, angularly aligned and axially advanced until portions of the first flange abut a respective one face of said mounting fixture marginally of said opening,(a) portions of said second flange within the plane of said remainder of said plate of said mounting fixture are radially closely surrounded by respective portions of said peripheral surface of said opening;

    (b) said two angularly short segments of said first flange are radially closely surrounded by respective of said two angularly short segments of said peripheral surface of said opening in said bulge so as to prevent angular rotation of said hose holder relative to said mounting fixture; and

    (c) said radially outwardly opening groove is positioned to receive a spring clip to act between said third flange and the respective opposite face of said plate of said mounting fixture for preventing substantial relative axial movement between said hose holder and said mounting fixture,the improvement wherein;

    said tubular member axially to the opposite side of said third flange from said first flange is provided with a band of threading which is adapted to permit a conduit connector to be threadedly joined to said tubular member;

    said tubular member axially to the opposite side of said first flange from said third flange is provided with a sleeve which is adapted to closely circumferentially surround said axially short region of said length of hose;

    a second tubular member, separate from the first-described said tubular member;

    said second tubular member having a tubular nipple portion adapted to be telescopically fitted into said axially short region of said length of hose, to extend out of said end of said length of hose, and to be generally coaxially spacedly surrounded by said first-described tubular member radially inwardly of said sleeve and said radially outwardly opening groove;

    said second tubular member further having a flared sealing annulus formed thereon so as to extend radially outwardly from said tubular nipple portion at a site located axially to the opposite side of said third flange from said second flange of said first-described tubular member, this flared sealing annulus being adapted to circumferentially seal with a corresponding surface of a conduit connector when such conduit connector is threadedly joined to said first-described tubular member by said band of threading; and

    cooperatively engageable surface means on said flared sealing annulus and on said first-described tubular member, these surface means being adapted to engage for fixing said second tubular member with respect to said first-described tubular member against axial movement of said surface means of said flared sealing annulus beyond said surface means of said first-described tubular member in the direction towards said first flange.
