The history of of our automatic hand injector and its design and development began almost 50 years ago in Seattle Washington. We bought ( then named) Au-rus Explosion Wax Pattern Company from Ruth McCallister in 1990. She told us she was looking for a better injector that would be easier to use and faster than what she could find at any of the jewelry supply companies at the time. Her husband was a machinist and he did the design and manufacture of the orininals. They did not want to take on the project of manufacturing them and selling them on their own so they let Vigor have the design for free. Vigor started selling them under their name with a wax pot. When we bought Au-Rus we got 3 of the originals made by Ruth's husband. We bought 4 from TSI with vigor's name on the wax pot. We have been using these injectors for all these years. We did not think there would be a problem getting more when we needed them. In the spring of 2006 a friend of mine saw mine and wanted to know where to get one. I told him where I thought he could get one. It turned out that Vigor went out of business about 15 years ago and the injector was not chosen by Gorbet International (who bought out Vigor),to be kept in their product line of merchandice. An executive at Gorbet who used to work for Vigor told me that Vigor was not the original manufacture of the injector. He said Vigor had purchased the injectors from Swest. Swest is also out of business. He told me Gorbet bought all rights to any products that Swest had been manufacturing and Stuller bought all their stock. I ask him if he knew if they had any legal ties to this injector that would stop me form manufacturing the injector and marketing it on my own. He told me that Swest did not do the actual manufacturing themselves but he did not know who did it. When they (Gorbet) chose a hand operated wax injector to put in the product line they chose another kind that is still in there catalogue but that he did not remember why the one was chosen over the other. He told me that Gorbet had no legal ties to the injector that would stop me from manufacturing it on my own. We decided to manufactuer them here in Kellogg,Idaho.
I decided to manufacture the injector using brass. It is an easy metal to work with and many parts and pieces that are pre-manufactured are already available and can be altered to meet the requirements of what I could see that I needed for parts from the original injectors.
