Denver Siren patent

Hmmm...Don't know a thing about warning sirens other than I just took two down from the rooftop of a building I own in a small town in Ohio. The "newer" siren is a Sterling 5 H.P. 3 phase unit M48. I believe it was installed in the early 50's.

The older model looks very similar to the schematics that I just looked at regarding the Denver Siren Patent. It was made by the Century Electric Company out of St. Louis. It is an 8 hp unit, 110 volts, and what looks to say .60 cycle. Patented May 7, 1899 and Jan. 13, 1903.

Anybody have more info on these sirens or would like to purchase them? I am all ears. I do not want to scrap them.

Interested in selling? what is the pat. number?

Yes I am. Since my last post I have found out that the older siren is a Denver Siren. The motor driving it was made by the Century Company. As far as the patent number, I found the placard on the Denver Siren, but have found it impossible to read. Is there another area on the siren that I can find it?

No, not at I know of. The only thing I can think of would be on the main base some where their may be a stamped number or other ID.

Here I am about a year later from previous postings, and I still have the Denver Siren! Took some pics and attached...anyone interested in purchasing?

There are some good people there, and I'm sure one or two of them would be happy to buy the siren(s)

Also, some info on the siren,
Denver Siren was a trade name for sirens produced in the late 1800's and eary 1900's by the Hendie and Bolthoff MFG. and Supply company out of Denver Co.
