This weekend as many of you know was Veterans day, but not just ANY Veterans day: this Sunday was the 100th anniversary of the end of hostilities in the ‘War to End all Wars’.
In true Cantigny Park style we celebrated both on Saturday with our ‘Brew-it-Forward’ Veterans event, and on Sunday with the ‘Bells of Peace’ ceremony marking the end of hostilities and the 100th anniversary of the signing of the Armistice. My self and other museum volunteers brought out the Liberty to show the public and wore original WW1 uniforms to interpret the lives and history of those no longer able to tell their story. The truck performed fantastically in the frigid temperatures, and the public crowded around to see this wonderful marvel of a by-gone era roar to life. Our truck is a second-series assembled from parts of first and second series trucks alike, so we have taken to calling November 1918 its general time of creation, making this Veteran’s day its 100th birthday.
We hope that our impact was a deep one and that the public we talked to will not forget the importance of this conflict and lives lost during it. Though fading in American memory, the Great War will forever live on in the stories of those who knew others who experienced it, and through our continuing outreach. The Liberty Truck is a powerful living artifact that can help us to bring history and the memory of WW1 alive for generations to come. To all of you out there who have served, thank you for your service and happy Veterans day!
I previously posted back in October about one of two hard-to-find parts that I finally managed to come across for our truck. Now I’m here to talk about the other part I didn’t mention: the Carbide Gas generator!
Now, for those of you not familiar with the gas/oil lighting system on second-series Liberty Trucks, check out my earlier post here: Liberty Truck Lighting Systems PART 2: Did We Say Electric? We Totally Meant Gas and Oil… Now I am now and will forever remain on the lookout for the correct generator, but for the time being the model I found is about as good as its gonna get. The Liberty was issued from the factory with a ‘Solar’ brand model 1012-B Calcium-carbide gas generator. Now the biggest issue with brass-era automobile lighting is that there isn’t a whole lot of technical data out there immediately available for you in terms of measurements and model years. I have been hunting for a 1012-B for several months but never found anything close. I had reached out to several restoration specialists in the field of brass-era gas lighting, but none responded to my inquiries. However, as I would see the truck every day the empty bracket on the firewall mocked me and began to haunt my dreams. “When will I find you?” I asked myself. As I continued to search, I began to fear that I may never be able to truly complete our truck…
I got lucky one day, and noticed a generator which kept popping up on my search feed. The price wasn’t fantastic so I kept scrolling past it. But as days wore on and I continued to search it became evident to me that I may not find anything better for much less. It wasn’t a 1012-B, but the dimensions and design looked very similar- so I took a chance and it paid off. After some back and forth over tax-exemption (we are a 501c3 museum and the generator was coming from an estate sale which would’ve required us to pay state taxes), I settled on a price. It is in fact a Model 712 which is pre-dates the 1012-B by a few years, but works exactly the same: Water goes in the top, drips slowly onto Calcium carbide pellets which makes acetylene gas which powers the search light! At first glance all the parts are present on ours and appear to be functioning or capable of it, but we won’t be ale to tell for sure until we get it cleaned up and filled with some carbide pellets.
The 712 model has a few small features which differ from the correct 1012-B model. Most noticeable for us is the presence of mounting lugs molded into the generator body- these stick out in such a way that they make it impossible to mount on the truck. However, if ground-off, the dimensions are perfect for fitting to our truck ( the 1012-B had no mounts on it at all and is meant to ‘sit’ on a small lug mounted to the truck and is then secured to the firewall via a ring mount). The other major difference is the gas nozzle on the top of the reservoir- the 1012-B has only one whereas ours has two- intended to split the gas to be distributed to two headlamps. Ours only hooks to one main line which feeds the search light. If we simply plug or cover one of the two nozzles on ours, we should be good to go for functionality purposes or until we find a proper 1012-B to use. The other big difference appears to be the materials used; the older 712 is all brass construction whereas the 1012-B appears to have had a brass top reservoir and a steel or aluminum lower cannister which was painted black (prior to being painted drab to match the truck). However, I’ve been unable to confirm this as I haven’t been able to personally inspect an original.
All there is left to do now is remove the mounting points and round-out the reservoir rim, clean it up, paint it and mount it to the truck! Now if we could just find an original working fuel transfer pump….
