  • Fig. 10 is a transverse section taken along the line ill-40 of Fig. 9.
  • FIG. 1 shows a vacuum cleaner ID of standard construc- 6 tion having a suction hose ll connected thereto and attached .to an air conducting handle or wand l2 embodying the present invention.
  • a suction nozzle I3 is connected to the wand i2 in the usual manner.
  • The. wand I2 is formed of two tubular telescoping members It and [5 which are arranged so that the member M telescopes within the member l5.
  • a connector sleeve l6 which is adapted to receive the nozzle l3.
  • a sleeve I! having an outwardly extending radial flange Illwhich rests against the end of the member H for positioning the-sleeve H thereon and which extends so slightly beyond the outer surface of said member to provide a stop in the manner to be described.
  • the sleeve 11 is also provided with radial flanges l9 and which are spaced to form an annular channel ing material 23 is held.
  • This packing material is preferably made of soft or elastic materiahsuch as felt, leather or the like and forms a sliding fit with the inner surface of the member l5.
  • a sleeve 26 is attached to the free end of the '30 member l5 and is provided with a radial flange which seats over the end of the member l5 and projects inwardly to engage the flange 20 ofthe sleeve I! for limiting the telescoping movement,
  • the sleeve 24 is ex-' '35 tended beyond the flange 25 to form a tubular connecting member 26 which is adapted to be connected to the hose II.
  • This connecting mem-, ber 26 is preferably made somewhat resilient so as to securely but detachably engage said hose.
  • the pther end of the member l5 carries a sleeve 30 which issimilar in form to the sleeve l'l above mentioned .and is provided with a radial flange 3
  • the sleeve 30 is also provided with radial flanges 32 and 33 which are spaced to form anannular channel-34 therebetween in which packing material 35 is held.
  • This packing matepacking material 23 above the rial is similar to the mentioned and provides a sliding fit with outer surface of the member ll.
  • pack- 25 therebetween in which pack- 25
  • the members l4 and 15 are made of any rigid material, such as metal, synthetic resin or other molding composition and that the sleeves above mentioned are rigidly secured thereto in any convenient manner.
  • a suitable means is provided for clamping the packing material 35 against the outer surface of the member l4.
  • this is accom plished by forming a plurality of spaced flexible tongues 36 in the sleeve 30 in engagement with the packing material 35.
  • These tongues 36 are provided with outwardly extending projections or bosses 31 for the purpose to be described.
  • a rotatable locking ring 46 is positioned around the sleeve 30 and is provided at its ends with inturned flanges 4
  • the ring 40 is provided with a plurality of spaced depressions or recesses 43 which correspond in position to the projections 31 on the tongues 36 and are arranged to provide clearance for said projections when they are positioned in alignment therewith.
  • the ring 40 is positioned to bring the recesses 43 into alignment with the projections 31 of the tongues 36 so as to release the members i4 and I5 for relative telescoping movement. After suitable adjustment of these members has been made, the members are locked in adjusted position by rotating the ring 40 slightly so as to depress the tongues 36 and clamp the packing material 35 against outer surface of the member H as above described.
  • the members are locked in adjusted position by rotating the ring 40 slightly so as to depress the tongues 36 and clamp the packing material 35 against outer surface of the member H as above described.
  • member I4 is sufficiently long to extend beyond the member i 5 when the members are in fully telescoped position so as to provide a grip for the operator to be used in adjusting the members.
  • the members I4 and I5 and the sleeves l1 and 30 are arranged in the manner set forth above, In this embodiment, however, the tongues 36 in the end of the sleeve 30 are omitted and a semicircular saddle 45 is loosely mounted between the packing material 35 and the sleeve 30.
  • This saddle is provided with a projection 46 which extends through a suitable aperture 41 in the sleeve 36.
  • a lockingring 48 is positioned over the sleeve 30 and is provided with inturned flanges .49 and 50 extending over the flanges 32 and 33 of said sleeve 30 to secure the ring 48 in position thereon.
  • the ring 48 is provided with an outwardly extending portion 5
  • the members [4 and I5 are locked in any adjusted position by rotating the ring 48 in a clockwise direction, as viewed in Fig. '7, so as to cause the cam surface of portion 5! to engage the projection 46 and depress the saddle 45, thereby clam-ping the packing material 35 against the outer surface of the member [4.
  • the sleeve 48 is rotated in a counter-clockwise direction until the shoulder 52 engage; the projection 46 as shownin Fig. '7. In this position the cam sur face of portion 5
  • provides clearance for the projection 46 and releases the pressure on. the saddle 45.
  • the various parts are similar to those described above with, the exception of the sleeve 30.
  • the sleeve 30 is provided with a peripheral groove 56 of substantial width for the purpose to be described and is provided with a conical end portion 58 beyond the radial groove 56.
  • a locking ring 59 extends over the conical end 58 of the sleeve 30 and is provided with an inturned, flange 60 which engages and slides in the radial groove 56.
  • the outer end of the locking ring 59. is provided with an inturned flange 6
  • the conical member 62 is provided with a plurality of spaced axial slits 65 between which resilient tongues 66 are formed.
  • the conical member 62 and the conical section 58 of the sleeve 30 are arranged so that axial movement of the conical member 62 causes pressure to be exerted by the conical section 58 which depresses the tongues 66 and clamps the packing material 35 against the outer surface of the member l4.
  • the members are clamped in any desired position or are released by causing the axial movement of the locking ring- 59.
  • the surface thereof may be fiuted as indicated in Fig. 9 or may be otherwise formed with means the following claims when interpretedin view of the prior art.
  • What 1 claim is: g 1.
