  • Fig. 2 is a cr-sectional view taken on'the line i--2f of Figs. I and 4;
  • Fig. 3 is a bottom view of the nozzle;
  • Fig. i is a sectionalview taken on the line of Figs. 2 and 3;
  • Fig. 54s a perspective view of'the nozzle;
  • Fig. 6 shows part of a second embodiment of the invention and is a front view;
  • Fig. 7 is a sec viewta ken on the line
  • Fig. 8 is a top view of another p nozzle adapted to be secured to the in Figs. 6 and 7;
  • Fig. 9 is a cr-sectional view taken on the linet-stofliigti i
  • Fig. id is a detail view taken in the direction it -it with respect to Fig. 8; and
  • p Fig. 11 is a cross-sectional view similar to Fig 7, but with the part shown in Figs. 8 through 10 secured in place.
  • the nozzle includes a shank In of generally tubular form and, adapted to fit onto the end of a hose connected with a source of suction, such as a unit including a dust bag, a fanand a motor.
  • a source of suction such as a unit including a dust bag, a fanand a motor.
  • Front and back walls H and I2 and end walls It extend downwardly from the shank and are flared outwardlyto form an elongated mouth portion.
  • the walls ii and 12 may be parallel as shown.
  • a bridge piece I4 is centrally disposed and extends between walls H and H.
  • the bridge piece may be integral with the walls II and 12.
  • Centrally disposed in the bridge piece is a vertical passage 18.
  • the loweredge of this passage is or the substantially in line with the contacting edge l 'l of the nozzle.
  • Passage I6 is in alignment with the internal passage of the shank portion Ill.
  • the bottom of passage l6 forms a small nozzle opening. This nozzle is preferably round.
  • the bridge piece H divides the lower part of the space interior of the nozzle so as to form two lateral elongated openings IS.
  • the lateral openings and the passage I 6 communicate centrally with the passage within the shank portion. 10
  • Grooves it are formed in the lower surface of the nozzle in the bridge piece It and extend to the outer edges as shown in Fig. 1. These grooves allow flow of air laterally of the nozzle in contact with the surface of the piece to be cleaned 1
  • the entire nomle may be cast in one piece as in this embodiment and may be made, for example, of aluminum.
  • the nozzle is made in two parts, each part being stamped from sheet metal.
  • the upper body part has a cylindrical portion 2
