Suction cleaner air inlet device
First Claim
1. An air inlet device for a tank type suction cleaner having a vertical tank with an air inlet opening in a wall thereof, comprising means for engaging the tank wall at said opening, deflecting means within said tank supported by said means for engaging the tank wall at said opening, said deflecting means extending substantially horizontally in both directions to deflect the incoming air in two substantially opposed directions, said deflecting means comprising a generally semicylindrical member with the curved portion spaced inwardly from said opening and the terminating portions of said member extending in a direction towards the wall of said tank, a lower edge of said deflecting means, where air is discharged from said deflecting means, having a lip inclined slightly upwardly to give an upward inclination to the path of the discharged air.

Abstract
An air inlet device for a suction cleaner of the vertical tank type where the vertical cylindrical tank has an air inlet opening in an upper portion of the wall, has a means for mounting the device to the tank wall with a deflector positioned in front of the inlet opening to deflect air entering the tank. The deflector is a generally semi-cylindrical member with its curved portion spaced inwardly from the opening and extending horizontally in both directions to deflect incoming air in only two substantially opposed directions.

2. An air inlet device for a tank type suction cleaner having a vertical tank with an air inlet opening in an upper portion of the wall of said tank, comprising a cylindrical mounting portion for mounting within said opening and having a central passage, a base member on the inner end of said mounting portion, said base member having a curvature conforming to the curvature of the tank wall, a semi-cylindrical deflecting member on said base member forming an elongated passage communicating with said ceNtral passage and adapted to extend horizontally within said tank adajcent the tank wall for deflecting incoming air in only two opposing directions, said deflecting member having on a lower edge thereof at a point of discharge from said device, a lip inclined slightly upwardly to give an upward inclination to the path of the discharged air.

3. An air inlet device for a tank type suction cleaner having a vertical tank with an air inlet opening in an upper portion of the wall of said tank, comprising a semi-cylindrical deflecting member positioned in front of said inlet opening with the axis of said deflecting member being substantially horizontal and the curved portion extending inwardly from the wall, support flanges on the terminating portions of said deflecting member, and fastening means extending from said tank wall and engaging said support flanges to mount said deflecting member in position, said deflecting member having, on a lower edge thereof at a point of air discharge from said device, a lip inclined slightly upwardly to give an upward inclination to the path of the discharged air.
