Anybody have a COX Safety Igniter ?
I'm looking for somebody that might have some COX ignters. They were unique in the annals of model rocket igniters. If anybody has one could you take some close up pics with a ruler and/or take the dimensions itself. Thanks In Advance

Hi Terry, Here are a few photos of the Cox Safety Igniter with dimensions in millimeters. Hope this helps. Also attached is the Cox Engine Instructions with details of the Safety Igniters. PM me your address and I will gladly send you one of the Cox Safety Igniters for free. Kind regards, Jeff Jenkins aka: Faithwalker NAR #46879 SR Last edited by Faithwalker : 01-23-2022 at 12:07 AM. |

They were the ultimate in "plug and play". Mine are somewhere in an ammo box of collectable motors.

That’s an interesting igniter but I don’t remember them. When were they available?

Early '70s timeframe. They plugged into a holder, so there weren't any microclips. I would just unfold the metal strips to use with a standard launch system. Chas

According to an L.M. Cox Catalog circa 1971, Cox Safety Igniters were provided with each pack of Cox model rocket engines and they were available separately in packs of six. The Cox part number for the blister pack of six Cox Safety Igniters was #5022. See photos attached. The blister pack photo shows that the Cox Safety Igniters were made at the Cox Center in Santa Ana, California, where public tours could be scheduled once upon a time. I do have a few 6 packs of the Cox Safety Igniters that were sold in Michigan Model Distributing Co. packaging out of Grand Rapids, Michigan, but I have no idea when these were sold. See photo attached. There is some important Cox Rocket Motor History at the following link, https://forums.rocketshoppe.com/showthread.php?t=19421, that has bearing, I believe, on the limited availability of the Cox Safety Igniters. It appears from all the information available so far, that Cox Model Rocket Engine and Cox Safety Igniter production began sometime in the first half of 1970. As documented in the referenced Cox Rocket Motor History thread, https://forums.rocketshoppe.com/showthread.php?t=19421, there was an explosion at the L.M. Cox Manufacturing Plant in Santa Ana, California on June 11, 1971, which killed two employees and injured six others in the engine making area where black powder was used in the production of the Cox model rocket engines. From all available photos of Cox model rocket engines that I have found so far, there does not appear to be any Cox Model Rocket Engines produced after the June 11, 1971 date at the L.M. Cox facility in Santa Ana, California. There have been some references to the possibility of MPC (or others) manufacturing model rocket engines for L.M. Cox Company after the June 11, 1971 date, but there has been no definite evidence produced so far whether this occurred or not. It appears there is evidence that the L.M. Cox Company did continue selling their line of ABS plastic model rockets and their existing stock of model rocket engines until, at least, the end of 1973, or until stocks were depleted before they stopped marketing model rocket products in the early 1970's. Therefore, the Cox Safety Igniters were available, at least, until supplies of the Cox model rocket engines lasted or until hobby shops sold out of the packs of igniters. A portion of the original L.M. Cox model rocket line was revived in the early 1990's, but Cox never again produced model rocket engines until Cox was purchased/absorbed by Estes/Centuri Corp. in 1996. All Estes-Cox model rocket engine production continued at Estes Industries in Penrose, Colorado, using the Estes model rocket engine design and production equipment and the engines were packed with the Estes igniters. If anyone has any evidence of L.M. Cox Model Rocket Engine or Safety Igniter production after June 11, 1971, or has original Cox model rocket engines dated after that date, please let us know about it and please share photos if possible. Thanks. Kind regards, Jeff Jenkins aka: Faithwalker NAR #46879 SR Last edited by Faithwalker : 01-24-2022 at 01:30 AM. |
