To Whom It May Concern;

I have a Dyo-Flex piece of equipment. That I have no clue how old it is. I do know it is older than the 1960’s. If I had to guess I would say between 1940’s and the 1950’s. I did a web search on this and got bumpkins and this equipment. So in the search for answers I stumbled across this web site. Now hate to pass this search off on someone else, but I’m stuck and hit a dead end. So thank you all in advance.
Okay here is what I know about it. It was owned by my great grandfather. What I was told by older family members that known him when he was alive. That he was a cobble smith and leather smith in northern Wisconsin. I was told that he made just about anything out of leather. That’s the history of the former owner of this equipment. I can’t ask no one family, cause the ones that would know are now gone.
Now on to the specks, I have the numbers, measurements, and photographs. I will try to give all information that I can give. First let’s give you the tag numbers and other information on the tags. The back tag has a General Electric Motor model tag and that number is 5KH45KB22X. The next tag is located on the font right side. That tag has on it Serial Number H-18956. Which I believe is a Dyo-Flex tag? There is one more tag. That tag is located on the top center. Here what that tag has on it. Dyo-Flex Dyo Chemical Company Dallas Texas. That is it for tags.
Now here are the measurements L10 ¾”, W 6 ¼”, and H 10 ¼“
Here is the description of the pump / compressor. First it is all flat black industry type finish. Now on the front there is a removable glass jar on the intake. Inside the jar there is a pipe cleaner on it. The pipe cleaner goes all the way though into the air pump. Now here is what else that is in the removable glass jar. There are brass fittings wrapped in a felt like stuff. Now on the top on the
air pump there is this cast iron tower, with 3 bolts in it and a rubber gasket. On that tower there is an exit air outlet tube. And that is where there is another type of jar. This one looks like a fuel bowl off an old tractor. But inside the fuel bowl looking thing. There is a black, hard, and oily stone with a big spring under it. That stone looks like an air stone for fish tanks.
I have photographs. The photos are from all angles. Some are with the attachments removed for closer photos of the attachments for better viewing of them. I have also included photos of the tags. I tried to include must information as I can in the photos.
Here are a couple of bonus questions. What goes in the front of the removable glass jar on the intake? Was there an air clearer / air filter attach to it before it reach the pump? Was there a liquid that went into the removable glass jar and get pump though the system? Did it have a pressure dial gauge? Any information on this would help.
Only thing I did to it was install a new power cord and test it. The old power cord was fayed and bare wires showing though. It runs very well and it is very noisy compared to my shop air compressor. I did not hook an up a pressure gauge to it. So I don’t know the pressure it produces in psi.
One more thing, there is a homemade gun like thing that came with it. It has a long brass 3/16” tube that is capped and brazed sanded then a 1/16” hole drilled in the end. That tube is mounded on a very small aluminum I beam. That measures about 3/8” wide and about 5” long. That beam is mounted on an old pickle jar lid. Inside that jar there is another tube the reaches almost to the bottom of the jar. That tube goes though the lid and has steel air cap from a vehicle. That cap also has a 1/64” hole drilled into the top of the cap. This gun looks like a crude air brush.
