A coating head assembly incorporating a replaceable breakaway link. The breakaway link connects two portions of the coating head assembly and has a sharp bend defining a weakened portion. In the event of a collision, the breakaway link will break to reduce the likelihood of breakage of any other part of the coating head assembly. Repair then only requires that the link be replaced, rather than the coating head assembly to be rebuilt. This invention reduces the coating head repair time from a fifteen-hour job of rebuilding the coating head assembly to a three-hour job of tooling a new link.

1. A breakaway coating head assembly comprising:a coating head applicator;a first coating head portion having first and second end segments, the first end segment of the first coating head portion being connected to said applicator;a breakaway link having first and second end segments, the first end segment of the link being connected to the second end segment of the first coating head portion, the breakaway link having a weaker portion that is weaker than a remainder of the breakaway link, the weaker portion being defined by at least one sharp bend in the material;a second coating head portion having first and second end segments, the first end segment of the second coating head portion being connected to the second end segment of the breakaway link and the second end segment of the second coating head portion having a blade extending therefrom;wherein the first coating head portion, the second coating head portion, and the breakaway link form a rigid arm. 2. The assembly of claim 1 where the assembly is a coating head assembly. 3. The assembly of claim 1 wherein the breakaway link is made of a material that is more brittle than the material making up the first portion and the second portion. 4. The assembly of claim 1 wherein the breakaway link has a weaker portion that is weaker than a remainder of the breakaway link, the weaker portion being defined by at least one sharp bend in the material. 5. The assembly of claim 1 wherein the breakaway link is made of a material that is more brittle than the material making up the first portion and the second portion. 6. A breakaway coating head assembly comprising:a breakaway link with first and second end segments, where the second end segment includes a portion that is weaker than the remainder of the breakaway link;a first coating head portion connected to the first end segment of the breakaway link;a second coating head portion connected to the second end segment of the breakaway link; wherein the first coating head portion, the second coating head portion, and the breakaway link form a rigid arm;a coating head applicator connected to the first coating head portion;a blade extending from the second coating head portion; andwherein the weaker portion of the second end segment of the breakaway link is weak enough so that, in the event of a collision with an object being coated, the weaker portion breaks, thereby preventing breakage of other components of the coating head assembly. 7. The assembly of claim 6 wherein the weaker portion of the breakaway link is defined by at least one sharp bend in the material. 8. The assembly of claim 6 wherein the breakaway link is made of a material that is more brittle than the material making up the first portion and the second portion. 9. The assembly of claim 6 wherein the weaker portion of the link is thinner than the first end segment.
