  • Patent number: 11235360
    Abstract: A drain clearing air gun includes a housing defining a main body, a handle positioned on a first end of the main body, and a nose positioned on a second end of the main body. A tank is at least partially positioned within the housing and includes a chamber for receiving pressurized air. A motor is positioned within a main body of the housing, and a pump is positioned within the main body of the housing and operatively coupled to the motor. The pump is driven by the motor to pump air into the tank. A pressure gauge is supported by the housing and includes an automatic shutoff feature. The pressure gauge is in fluid communication with the tank. When a predetermined pressure within the tank is reached the automatic shutoff feature is activated to stop the motor.

  • Publication number: 20210285197
    Abstract: A drain cleaning machine for moving a snake in a drain. The drain cleaning machine includes a rotating shell, a motor, radial drive mechanism, a translate mechanism, and a selection mechanism. The selection mechanism includes an actuating lever moveable between an activated position and a deactivated position, a selection plate moveable between a radial drive position and a translate position, and a push plate. The push plate is moveable in a first direction relative to the selection plate in response to the actuating lever moving to the activated position, and is moveable in a second direction relative to the selection plate in response to the actuating lever moving to the deactivated position. When the selection plate is in the radial drive position and the actuating lever is moved to the activated position, the push plate moves toward the selection plate to switch the radial drive mechanism to an engaged state.
