Definitions

  • the present invention has for its object to provide a simple and effective means whereby a rotary polishing brush may be quickly mounted underneath the nozzle of a vacuum cleaner and in such positionthat it may be driven from the shaft of thecleane motor, or removed therefrom.
  • Fig. 1 is a perspective view of a vacuum cleaner with the polish- -er applied thereto;
  • Fig. 2 is a perspective a View of the polisher and its supporting brackets, and
  • Fig. 3 is a detail view of the ratchet b mechanism to prevent reverse "rotation of the polisher.
  • Such a cleaner in normal use is also provided with a relatively small rotary brush which is located wholly within the nozzle except for the tips of the bristles which brush the surface being cleaned.
  • the brush is driven by a belt from a small pulley 17 located on the front end of the combined armature and fan shaft 10.
  • the brush is carried on a spindle having bearings at its ends and these are mounted in spring hangers 18 which are supported by the end walls of the nozzle..
  • Each hanger comprises a stationary member 19 which is firmly supported by the nozzle wall through part 40 and a movable member 20.
  • the ends of the two members which are pivotally united at the top 'are pressed toward each other by a flat steel spring 21.
  • the members vhave out-turned lower ends and the space between them is less than the diameter of the brush-supportin g bearings.
  • polisher 2-5 indicates a relatively large diameter polisher in the form of a brush of any suitable construction having bristles which are stifl enough to support the weight of the cleaner without appreciable bending thereof way between the ends of the brush and by means of'which and a belt 27 the brush is driven by the pulley 17
  • the polisher has bearings 28 at its opposite ends and to each is secured a bracket 29, the lower portion 30 of which issituated wholly below the lips of the cleaner nozzle and the upper part 31 wholly within the nozzle, the two parts being connected by a horizontal offset portion, element or member 32.
  • the portions of the brackets which carry the heads 33 are so spaced apart in an axial direction that the distance between them is only slightly less than the distance between the members 40 which 26 indicates a pulley located mid-f support the hangers. As a result of this the polisher is held against endwise movement.
  • the two brackets are preferably made of I punched sheet steel and are wholly independ- -ent of each other, their only connection being through the spindle of the polisher and *tlrebearings thereof.
  • On the inner member of each bracket is fastened a relatively small ,7 rounded head 33 which is of such size as to once seated in the hanger it Wlll be retained permit of being pressed into a spring hanger through the open end by the application of a relatively small amount of pressure. ⁇ Vhen by the pressure exerted by the flat spring 21 on the two members of the hanger, WhlCh tends to move the-members toward each other at all times.
  • offsets permit of the use of a olisher which is at least as long as the nozz e opening thereby ensuring the polishing of a substantial area at each I stroke.
  • the bearings being wholly outside of the nozzle and being'mounted on brackets im ose no restrictions as to the length of the po 'sher.
  • brackets in addition to holdin the,.u per ends of the brackets also serve to 0 amp t e upper surfaces of the offset parts 32 against the under surface'of thenozzle. This is due to the-inclined fingers or parts of the hangerswhich engage theheads 33-at two pointsbelow the maximum'diameter thereof'and hence to pull the brackets upwa'rdl Inmounting the po isher in place, the first ste is to remove what ma be termed the norma brush together wit its driving belt.
