housing 22 the connection facilitates the manipulation of the vacuum cleaner attachment 20 in this embodiment of my invention and those discussed hereinafter it is preferred that the transverse axis 64 about which the vacuum fitting is vertically pivoted be located about one third of the fore to aft distance between the nose and rear end of the attachment this also allows the operator to exert downward pressure on the attachment to thereby promote its cleaning efficiency as is perhaps best shown in fig3 pivot member 66 is made up of two transversely extending circularly sectioned pivot lugs 68 and 70 which are integral components of vacuum fitting support 62 and are rotatable about transverse axis 64 which lies in the vertical midplane of housing 22 the two pivot lugs 68 and 70 extend through openings 74 and 76 in the vertical plenum defining side walls 55 and 56 of vacuum cleaner attachment housing 22 this rotatably journals the lugs in those side walls the above mentioned vacuum fitting support 62 has a generally rectangular section and a central fore and aft extending passage 77 that passage provides fluid communication between vacuum fitting 60 and the plenum 53 which connects the latter to those vacuum chambers 46 and 48 in the two wings 24 and 26 of housing 22 housing 22 is biased downwardly relative to fitting 60 by a spring 78 coiled around pivot lug 70 one end 80 of this spring is fitted into a slot 82 through pivot lug 70 the other end 84 of spring 78 is fitted into a slot 86.
