摘要： A water mist-producing device includes a nozzle structure having a flow passage connected to a pressurized water source. A cylindrical pin is coaxially disposed in the passage so that pressurized water flows through an annular space between the pin and the passage wall surface. The downstream end of the pin abuts a transverse end wall having an exit hole assigned with the pin axis. Small angularly disposed flow ducts are defined in the downstream end portion of the pin to conduct jets of water across the end of the pin and through the exit hole. The angular disposition of the flow ducts effects spinning about its axis.

摘要： An auxiliary dado shaft to support a plurality of rotary saw blades in a laminated pack for cutting wide grooves and dados, is provided with a central bore for receiving a through bolt for simultaneous securement of the blades together and engagement of a mating thread in the motor drive shaft. A tubular socket on the inboard end of the auxiliary dado shaft is adapted to engage the stubshaft of the drive motor and is secured thereto.
