Near its lower end, the drum 2 carries a transverse frame element 93, comprising radial spokes or webs 43, 47 and 48 and a ring 89 carried by the inner ends of these spokes. The ring is rigidly secured to nut 29 through connection with its lower transverse flange 30, as by l screw bolts 3| I.

Nut 29 is tubular, and has an internal surface 49 of a diameter somewhat greater than the external diameter of shaft 21 (see Figs. 3 and The inner surface 49 of the nut has a spiral V-shaped groove 50 of a pitch corresponding to the pitch of groove 44 in shaft 21. Balls 5| are received between the nut and shaft within grooves 44 and 50 to form the equivalent of a threaded connection between the nut and shaft. The halls, of course, reduce friction to a minimum as the nut travels along the shaft. At one side, the nut has a diagonal recess or slot 52 communicating with groove 50 near its upper and lower ends through substantially tangential openings 53 and 54. Ball return channel or guide element 55 is received within recess 52, as best seen in Fig. 6 and forms, with nut surface 56 at the inside of recess 52, a return passage 51 directin the balls either upwardly or downwardly between I openings 53 and 54. Thus, as the nut is rotated for upward advancement along shaft 21, the balls travel downwardly along groove 50, out opening 54 in the nut, upwardly through passage 51, and through opening 53 into the upper end of groove 5|. Similarly, upon downward movement of the nut, the balls travel upwardly along groove 5|] and return downwardly through passage 51. Each end of guide 55 has an inwardly extending ear 95 preventing movement of the balls along the spiral grooves beyond the corresponding tangential opening 53 or 54 (see Fi 7).

The drum is normally urged downwardly by spiral spring 58, which bears, at its upper end, against flange 59 of nut 60, carried by the upper end of shaft 21. At its lower end, spring 58 bears against thrust ball bearing 6|, which in turn engages ring 89 of frame element 93. Air and water are supplied to the hoses through valves 62 and B3 and upwardly extending conduits 64 and 65,

respectively. Conduit 65 is connected to the lower end of member 34 by nipple 63. Conduit 34 extends upwardly at the side of space l8 and then horizontally within space M to connect with member 34a, which corresponds to member 34 of the lower reeling unit except for the provision of a side rather than a bottom inlet.

Swivel inlet connection 36 includes a tubular body 61 rotatably carried about stationary shaft 33. As seen in Fig. 4, body 61 contains a pair of ball bearings 68 carried within enlarged diameter bores 69 at opposite ends of the body, and engaging shaft 33 at 10. Beneath the upper of these ball bearings, and above the lower one, the body carries a pair of sealing O-rings 1| preventing fluid passage outwardly along shaft 33. Between these O-rings, the body has an annular recess 12 of a diameter greater than the external diameter of shaft 33, to form, with the shaft, annular fluid conducting passage 13. At one side,

4 body 61 has an outwardly extending passage 90 communicating with passage I3 and leading into elbow connection 14. Shaft 33 has an internal passage 15 directing water or air from space 16 within member 34 upwardly and then outwardly at H into annular passage 13.

Fluid supply conduit 3| includes a pair of axially extending rigid portions or pipes 18 and i9, and an intermediate flexible portion or tube 83, connected to the rigid pipes by fittings 8| and 82. The first or inlet pipe 19 is connected at its lower end to elbow 74 and passes upwardly through axial opening 83 in drum spoke 46, thus being maintained in predetermined angular relation with respect to the drum. Opening 83 is slightly larger than the external diameter of the pipe to permit axial movement of the drum relative to the pipe. Rigid portion or pipe 19 of the supply conduit extends through an opening 84 in spoke 48 and connects at its lower end with block 85, to which. the inner end of the hose is secured by threaded reception of fitting 86. Block 85 contains inner passages 9| and 92 directing fluid from pipe 19 into the Flexible tube 8|) forms an axially extending return curve or loop at 81. As will be understood, fitting 8| is maintained by pipe 19 against axial movement, whereas fitting 82 moves upwardly and downwardly with the drum. Thus,

as the drum moves axially, loop 81 advances, as

for instance from the normal condition of Fig. 2 to the partially withdrawn condition of Fig. 3. Of course,,the supply conduit rotates bodily with the drum at all times by virtue of its passage through the spokes of frame element 93.

In operating the dispensing units, valves 62 and 53 are first opened to supply air and water respectively to fittings 25 and 26. Water, for in stance, flows upwardly through line 65, nipple 66, passage 15 in member 34, and passage 15 in the swivel shaft, then outwardly into annular passage 73, through elbow l4, supply conduit 5|, block 85, and into hose 2|. Air follows a similar course from line 64 and member 34a into the hose 22. Upon retraction of either hose, the corresponding drum is rotated, and, by virtue of nut 29, advanced upwardly along shaft 21. With this vertical or axial movement of the drum, flexible portion of conduit 3| advances in the manner previously described, to the condition of Fig. 3. Upon release of the withdrawn hose, spring 58 returns the drum downwardly along the shaft, resulting in reeling rotation of the drum and return of the entire apparatus to the normal condition of Fig. 2.

I claim:
