Claim 14:
15. An orthodontic appliance as claimed in claim 14, and wherein the first, intermediate tube is defined by an elongated main body, having the opposite first and second ends, and an outside and inside facing surface; and wherein the elongated main body of the first, intermediate tube is coaxially aligned relative to the longitudinal axis of the outer, cylindrically shaped tube, and further has a length dimension which is less than about the length dimension of the outer, cylindrically shaped tube, and wherein the outside diametral dimension of the first end of the elongated main body is less than the inside diametral dimension of the internal cavity of the outer, cylindrically shaped tube as measured at the first end of the outer, cylindrically shaped tube, and further the elongated main body of the first, intermediate tube has an outside diametral dimension as measured at the second end thereof, and which is less than the inside diametral dimension of the internal cavity of the outer cylindrically shaped tube as measured at the second end of the outer cylindrically shaped tube, and wherein the inside facing surface of the first intermediate tube defines the internal cavity which extends between the first and second ends thereof, and which further has an inside diametral dimension when measured at the first end which is greater than inside diametral dimension when measured at the second end, and wherein the first intermediate tube is telescopingly, and reciprocally moveable along a given coaxially path of travel relative to the outer, cylindrically shaped tube.
