Chiropractic adjustor
First Claim
1. A chiropractic adjustor comprising a hollow housing, a thrust member having a patient contact member at one end thereof mounted in the housing, an electrically energized solenoid having a core mounted in the housing so that the housing is longitudially movable relative to the thrust member and the solenoid, the solenoid being mounted in alignment with the movable thrust member and imparting impact energy thereto when the solenoid is energized thereby imparting an impact energy to the thrust member which transfers the impact energy of the solenoid core to a patient, spring means interposed between the housing and solenoid which is compressed by inward movement of the housing toward a patient, and control means for triggering the solenoid to impart impact energy from the core to the thrust member which is reproducible thereby providing a reproducible transmission of energy to the patient, the control means being responsive to the compression of the spring means which is directly related to pressure between the patient contact member and a patient when the patient contact member is held against the body of a patient, the control means triggering the solenoid when the pressure between the patient contact member and a patient reaches a preset value.

Abstract
A chiropractic adjustor for applying an adjustment energy to a patient through a plunger having a resilient or cushioned head with the energy applied to the plunger being supplied by a solenoid assembly capable of producing an adjustable and reproducible energy or force that is transferred from the solenoid to the cushioned plunger thereby providing a chiropractic adjustor that is solenoid operated and capable of providing precisely reproducible energy settings over a wide range and the capability of providing a reproducible energy level and a reproducible contact energy or force between the adjustor and patient.
