The Wm Schollhorn co made many vintage parallel jaw pliers, which these are, and specialty pliers.  They were also sold under the names Sargent and Bernard tools.  The handle design of this tool was used quite a bit by them.  I think it was used for pushing/plugging something together.  I spent a lot of time looking but just cannot find another image of them.  Here is a link to some info.

Dan, I see the similarity in the handles and the rivets, kind of sort of. You researched and that is awesome! Looks like you spent some time on it too, but I don't really see anything more beyond the handle style. Unless you are seeing some markings I am not. Do you think our tool in question is an old Sargent?

John, I am saying the pliers shown were probably made by the Schollhorn Co.  They were big in making parallel jaw pliers.  The pliers in question are parallel jaw pliers for a special use and Schollhorn made special use pliers too. Here is an images link to some examples of what all they made.

Whoa! Now that is compelling!!!!! I think you may be on too something here Dan! Looking at those images, it's almost identical, but for the main working portion, could it be perhaps a home made custom job someone did to a set of the Schollhorn pliers? Great job sir!

They look made too well made for a homemade job.  Another clue is the fact that they are bronze.  Being bronze makes them spark resistant in use so I tried searching natural gas lighting, bullet loading or reloading, phone company switch board cables but cannot find anything on them.  I have a feeling they are so obscure that only someone who had a job using them would know what they are.   

From the way they are built it is made to come together, compressing something.

i've been looking at spring actuated cylinders and it looks like it fits over a cylinder rod of some type to either compress it to put it together or to take pressure off to disassemble it.

Dragon that is one area I didn't consider. It sure had to be for one of a kind use.

I have a tool close to that which I used to push ends of air hoses into the hose. Parker Hannifin has some great push lock hose whichI use to sell the garages and body shops in the 60's and 70's.  These kind of tools were invaluable to each trade.

Looks like a plier for compressing a spring on a shaft.   Be more sure if i had it in hand....lol
