  • My invention relates to vacuum cleaners and more particularly to vacuum cleaners of the enclosed bag type.
  • cleaners of this type it is common to provide a casing within which are I disposed a motor-fan unit and a dust bag or other dust separating member.
  • a motor-fan unit In order to clean the dust bag of accumulated dirt, it is necessary to remove it and hence a removable closure member is.provided for this purpose. 10

  • closure-member it is also convenient to arrange the closure-member so that it clamps the vdust bag in place.
  • One of the objects of my invention is to provide a new and improved means for removably securing a closure member in place.
  • the closure member may be removed by a simple natural movement of a single handle member which movement first releases the closure member from engagement with the rest of the casing and thereafter removes the closure member.
  • My invention'further includes an automatic operating toggle mechanism which looks the closure member in engagement with the casing upon movement of the single handle member in theproper direction.
  • Another object of my invention is to provide securing means so arranged that this force has no tendency to cause release of the closure member from the casing.
  • Fig. 1 is a side view,'partially in cross-section
  • FIG. 3 is a cross-sectional view of an enlarged view of the portion of the device shown in Fig. 1 which embodies my invention, and is taken on the line 3-3 of Fig. 2; g v I n "Fig. 4 is a cross-sectional view taken on the line Fig. 5 is a cross-sectional view taken on the "line I5 ofFlg.4; n

If desired, this seam may be covered by' a rubber strip M. which serves as a bumper to prevent marring of furniture or the like with which the device accidentally may come in contact.
  • Lower stamping I2 is preferably formed withrunners i 5 and I6 for supporting the unit on a surface.
  • Casing I0 is reenforced and divided into three compartments by meansof bulkheads I1 and Ill.
  • the space I 9 between these bulkheads may be 20 v termed a motor-fan compartment and access thereto may be had by means of a removable cover member 20 secured in place in an opening formed in the bottom stamping.

  • the space M between bulkhead l8 and the adjacent end of the casing may be termed a 30 filter compartment and encloses a suitable filter element 25.
  • This end of the casing is "provided with an opening sufllciently large topermit the insertion and removal of the filter element, which opening is normally closed by means of a clo- 35 sure member 26.
  • v Member. 26 is provided with an exhaust opening 21 acrosswhich extends a plurality of vanes 28 for the purpose of directing air flowing therethrough' in an upward direction.
  • the space 29 between bulkhead I! and the ad-' jacent end 'of casingl0 may be termed a dust bag compartment.
  • This end of the casing is provided-with a preferably, though not necessarily, circular opening bounded by a flanged ring 30 which provides an outwardly facing seat v 3
  • Ring 32 is formed with an outwardly extending flange 33 which carries a packing ring 34 of rubber or other suitable compressible material.

  • the dust bag may now be removed from the compartment 29 and emptied. It is-then replaced in the compartment and. the cover member put back.
  • the handle 41 is turned or rotated in a clock-wise direction. This causes the rack to move downwardly and to rotate the gear segments 60 so as to project the latches 62 into engagement with the spring 66 contained in the recesses 65.
  • the latch 62 moves toward the right, as viewed in this figure, it deforms the spring 66, by virtue of the inclination of the fiat ring 30. This results in the formation of anair 7 tight seal around the opening.
