ABSTRACT:
A pneumatically actuated impact tool, for use by trained personnel in chiropractic treatment of the spine and other parts of the body, includes a resiliently tipped plunger reciprocably mounted in a cylinder having a tank, with a fitting for connection to a source of air under pressure. Air pressure is selectively communicated to the cylinder and thereby to the plunger by a valve mounted in an aperture in a wall separating the tank and the cylinder, and engaged by a valve lever which is pivoted in a handle attached to the tank and to the cylinder. A trigger is pivotally mounted on the handle and has a portion thereof engaging the valve lever, to provide a leverage to open the valve and allow the air pressure into the cylinder to drive the plunger in a single stroke against a compression spring mounted coaxially thereon to impart a desired impact to the patient.
