Abstract A multiple piece cutting tip for a cutting torch. An outer body with an inner body coaxially positioned therein forms a first passageway therebetween for transmitting preheat fuel and oxygen. A helical mixer in the first passageway more completely mixes the fuel and the oxygen. The first passageway includes a plurality of openings about the inner body at the tip end of the first passageway for preheating. The inner body includes a second passageway therethrough for the passage of cutting oxygen and the inner body includes a connection for changing the cross-sectional area of the second passageway. Radially extending ribs are provided about the outside of the outer body adjacent the tip for dissipating heat. The size of the second passageway may be modified by an elongate tubular member adapted to be threaded into the inner body and telescopically extend into the second passageway for changing the size of the second passageway.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
A cutting tip for attachment to the head of a cutting torch comprising, an outer body, an inner body coaxially positioned in the outer body and forming a first passageway positioned between the inner and outer bodies for transmitting preheat fuel and oxygen therethrough, a helical mixer positioned in the first passageway for more completely mixing the fuel and oxygen, said first passageway including a plurality of openings about the inner body at the tip end of the first passageway for preheating, said inner body having a second passageway therethrough for the passage of cutting oxygen, and releasable and replaceable adapter means connected to and extending into the inner body for adjusting the cross-sectional area of the second passageway.
Claim 2
Dependent Claim
119 words
A cutting tip for attachment to the head of a cutting torch comprising, an outer body, an inner body coaxially positioned in the outer body and forming a first passageway positioned between the inner and outer bodies for transmitting preheat fuel and oxygen therethrough, a helical mixer positioned in the first passageway for more completely mixing the fuel and oxygen, said first passageway including a plurality of openings about the inner body at the tip end of the first passageway for preheating, said inner body having a second passageway therethrough for the passage of cutting oxygen, and releasable and replaceable adapter means connected to and extending into the inner body for adjusting the cross-sectional area of the second passageway.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1 including, radially extending ribs about the outside of the outer body adjacent the tip for dissipating heat from the tip.
Claim 4
Dependent Claim
29 words
The apparatus of claim 1 wherein the adjusting means include, an elongate tubular body adapted to be threaded into the inner body and telescopically extends into the second passageway.
Claim 5
Dependent Claim
26 words
