Air powered reciprocator

A pneumatic powered oscillator comprising:

• (a) a cylinder of elongated shape having first and second opposite ends, said first and second ends each having means for introducing and exhausting pressurized air;
• (b) piston means having first and second opposite sides facing said first and second ends of said cylinder respectively and being slidably moveable within said cylinder between a first position closest to said first end of said cylinder, to a second position closest to said second end of said cylinder;
• (c) an arm means moveably responsive to the movement of said piston means and having an outward end extending latitudinally outwardly from said cylinder;
• (d) framework means removeably attachable to said outward end of said arm having extension members for the mounting of spraying means for the spraying of substances;
• (e) air logic circuitry means for the channeling of pressurized air of different pressures and amounts to each of said means for intaking and exhausting pressurized air at pre-determined times determined by the position of said piston within said cylinder, said air logic circuitry introducing a pre-determined amount of pressurized air to said means for intaking and exhausting pressurized air at said first end of said cylinder when said piston reaches said first position while concurrently exhausting a pre-determined amount of pressurized air from said means for intaking and exhausting pressurized air of said second end of said cylinder and introducing a pre-determined amount of pressurized air into said means for intaking and exhausting pressurized air at said second end of said cylinder when said piston reaches said second position while concurrently exhausting a pre-determined amount of pressurized air from said means for intaking and exhausting pressurized air of said first end of said cylinder, so that upon reaching said first or second position in said cylinder, pressurized air is introduced in front of said piston and pressurized air is exhausted behind said piston causing said piston to quickly reverse directions toward the opposite end of said cylinder while taking a minimum lag time in making the reversal of direction, said air logic circuitry further comprising a manually operated on/off valve for entering pressurized air to said air logic circuitry of said oscillator, a high pressure regulator with a filter for providing a regulated supply of pressurized air and filtering out undesired elements from the air entering said air logic circuitry of said oscillator, a lubricator means for imparting certain substances to the pressurized air to increase said pressurized air's viscosity, a low pressure regulator for providing a lower pressure air supply than that entering the high pressure regulator for use in said air logic circuitry of said oscillator, and a speed control valve for selecting pre-determined amounts of exhaust pressurized air from said cylinder to control the speed of oscillation of said piston.
