Definitions

  • the present invention relates to suction cleaners in general and more particularly to a new and improved dusting tool converter attachment to be used in combination with a suction cleaner.
  • the invention comprises an improved locking mechanism for a dusting tool converter adapted for the purpose of locking that converter to the suction cleaner.
  • a still further object is a provision of a new and improved dusting tool converter for use with suction cleaners, the locking mechanism of which is so designed that the converter cannot be accidentally displaced from its connection with the suction cleaner, and which tends to more firmly lock the converter to the cleaner upon relative movement therebetween.
  • Figure 1 is a side view of a suction cleaner with the converter comprising the present invention embodied therein, certain parts being shown in section; l
  • Figure 2 is a section upon the line 2 2 o Figure 3;
  • Figure 3 is a side elevation of the converter per se
  • Figure 4 is a bottom plan view of the converter
  • Figure 5 is a partial section upon the line 55 of Figure 1.
  • a modern suction cleaner comprises a motor 1, a fan chamber 2, and a nozzle 3, as in the usual suction cleaner.
  • a rotatable fan 4 is positioned within the fan chamber 2 where it can be rotated by the motor 1 to create a reduced suc- 45 tion effective to draw cleaning air through the nozzle 3 and into the fan chamber 2 by 'way of the inlet 5.
  • the cleaner is movably supported upon front and rear wheels 6 and 7 respectively while a handle 8, which is pivotally mounted as at 9, is provided by means of which the cleaner may be moved over the surface covering undergoing cleaning.
  • the nozzle 3 is provided with an opening 10 in its front wall immediately forward of the inlet 5 of the fan chamber and, when the cleaner is It is a further used as a floor-cleaning tool, this opening is covered by a suitable removable plate of a common type which is not shown.
  • a suitable peripheral shoulder 12 is formed on inlet 5 while the body of converter 11, which is formed as a conduit, is provided with an exterior flange 13 which is shaped to seat thereagainst, the relationship of the two parts at their points of contact being such that a substantially air tight seal is provided.
  • the outer end of the converter 11 is reduced in size, as at 14, and is provided with spaced protrusions 15, 15 which are adapted to seat within slots upon the cleaner end of the dusting tool hose which is adapted to be seated thereon.
  • the line A-A is formed as a circle around the pivot point 18 as a center and it is clear that the face 21 increases in its distance from the point 18 from its bottom to its top. This relationship is very important.
  • a key 22 is provided upon the top of the converter 11 substantially diametrically opposite from the lever 19.
  • a keyway 23 is provided in the nozzle 3.
  • a suction cleaner including a nozzle and a fan chamber, said fan chamber having an inlet into said nozzle and said nozzle having an opening spaced from and alined with said inlet, and a removable dusting tool converter extended thru said nozzle opening and seated in said inlet, a pivoted lever having a cam face carried by said converter and positioned so that said cam face contacts the interior of said nozzle adjacent said opening, the relationship between the lever pivot point and the cam face being such that said face approaches and contacts the inner wall of said nozzle as said lever is pivoted in one direction, and spring means urging said lever in the said one direction and tending to force said converter into said inlet.
  • a dusting tool, converter including a body formed as a conduit, the forward end of said body extended thru said opening in said nozzle and seated against said inlet, a lever pivoted on said body in said nozzle and extended outwardly thru said opening, said lever formed with a cam face in contact with the inner wall of said nozzle adjacent said opening, and a spring tending to pivot said lever relative to said body and so hold said cam against said nozzle, said lever being adapted to be pivoted to a position adjacent said body to disengage said cam from said nozzle and permit said body to be withdrawn thru said opening.
  • a dusting tool converter including a body formed as a conduit, the forward end of said body extended thru said opening in said nozzle and seated against said inlet, a cooperating key and keyway on said body and on said nozzle to prevent rotation of said body, a lever pivoted on said body insaid nozzle and extended outwardly thru said opening, said lever formed with a cam face in contact with the interior of said nozzle adjacent said opening, said lever including said cam being of such dimensions that when said lever is pivoted closely adjacent said body it does not interfere with the outward displacement of said body, and spring means urging said lever from said body.
  • a dusting tool converter for suction cleaners including a body formed as a conduit, a shoulder formed on the exterior of said body adjacent the forward end thereof adapted to limit the penetration of said body into a suction cleaner, a projecting key on said body, adapted to extend into a keyway to prevent rotation of said body, downwardly extending spaced walls on said body, a pin extended between said walls, a rearwardly extending lever pivoted on said pin, said lever formed with a cam face, a second pin between said walls adapted to limit the pivotal movement of said lever, and a spring tending to pivot said lever from said body.
