A traction device utilizes a harness connected to the body of a patient, such as the head or hips. The harness is connected by a clip to a tether which passes through a ratchet pulley connected to a first end of a spring chamber. A second end of the spring chamber is connected to a support. As tension is applied to the tether, the ratchet pulley incrementally applies traction to the patient as a first spring housed within the spring chamber deflects with the application of force.

Having thus set forth the nature of the invention, what is claimed herein is: 1. A method of incrementally applying traction comprising the steps of: providing a spring chamber having a body surrounding a first spring contained therein, said spring chamber connected to a ratcheting pulley operably coupled by a tether to a harness at a first end of the body with said ratcheting pulley located intermediate the harness and the spring chamber; said tether has a free end portion; securing a second end of the body, said second end opposite said first end, to a support; placing the harness on an appropriate location on a patient; removing slack from the tether intermediate the ratcheting pulley and the harness; applying tension to the tether, wherein the patient pulls on the free end portion of the tether to incrementally apply traction at a desired location to the patient through the harness with the ratcheting pulley at least assisting in incrementally shortening the tether intermediate the ratcheting pulley and the harness at a distance thereby at least assisting in incrementally increasing tension applied to the patient, and the ratcheting pulley retaining the tether at the distance without continued application of tension to the tether by the patient. 2. The method of claim 1 wherein the step of applying tension provides an audible click with the incremental application of tension. 3. The method of claim 1 wherein the step of applying tension deflects the first spring with the incremental application of traction. 4. The method of claim 1 wherein the step of applying tension compresses the first spring within the body. 5. The method of claim 1 wherein the harness is placed about the head of the patient and the step of applying tension to the rope applies cervical traction to the patient. 6. The method of claim 5 further comprising the step of locating a chair below the patient prior to applying tension to the rope. 7. A traction device comprising: a harness; a ratcheting pulley operably coupled to the harness by a tether; said tether has s free end portion; a spring chamber connected at a first end to the ratching pulley, wherein the ratcheting pulley located intermediate the harness and the spring chamber, said spring chamber having a body with a first spring located therein; a support connected to a second end of the spring chamber, said second end opposite the first end, wherein application of a force to the spring chamber intermediate the first and second ends alters the length of the first spring, and incremental shortening of the tether intermediate the harness and the ratcheting pulley allows for a patient to incrementally apply a traction force with the spring traction chamber with the patient incrementally shortening the tether intermediate the ratcheting pulley and the harness by pulling the tether on the free end portion of the tether at a location on the tether not intermediate the ratcheting pulley and the harness, and the ratcheting pulley maintaining the force once applied. 8. The traction device of claim 7 wherein the application of the force to the spring chamber compresses the first spring. 9. The traction device of claim 7 further comprising a second spring located within the body. 10. The traction device of claim 7 further comprising a first end cap at a first end of the body with a bore extending therethrough, a shaft extending through the bore, and a stop connected to the shaft within the body with said first spring located intermediate the stop and the first end cap. 11. The traction device of claim 10 wherein the shaft has a connection point external to the body for connecting to one of the ratcheting pulley and the support. 12. The traction device of claim 11 wherein the connection point and shaft are portions of an eye bolt. 13. The traction device of claim 7 wherein the tether is a rope. 14. The traction device of claim 8 wherein the harness is a head harness. 15. The traction device of claim 14 wherein the support has a connector connected to the second end of the spring chamber and is supported by a door. 16. The traction device of claim 15 further comprising a breakaway joint on the support. 17. The traction device of claim 7 further comprising a clip connecting the harness to the tether.
