1 Claim. (Cl. 15-158) The present invention relates to suction nozzles for vacuum cleaners.

The object of my invention is to provide an improved construction and arrangement in suctween the coupling and the suction nozzle permits the angular position of the tube l3 to be changed at will. The pivot pin 8 is located so close to the nozzle lips that there is substan- 5 tion nozzles and for a consideration of what I tially no tendency to tip the nozzle as it is moved. 5 believe to be novel and my invention attention The lower position of the handle is limited by is directed to the following description and the contact of the lower side of the coupling with claim appended thereto. the upper surface of the shoe 4. The upper In the accompanying drawing, Fig. 1 is a rear position of the handle is limited by an adjustelevation partly in section of a suction nozzle able stop l6 which contacts the upper edge of 10 embodying my invention; Fig. 2 is a sectional the arcuate wall I. end elevation of the suction nozzle; Fig. 3 is a In the rear side of the front nozzle lip is a bottom plan view of the suction nozzle, the recess ll in which is carried a brush IS. The brush being removed; and Fig. 4 is a perspective brush is supported by leaf springs l9 having view of the nozzle connected to a suction hose. their ends respectively fixed to the bosses 15 Referring to the drawing, there is shown a and to the brush.
