Water Motor Gong / alarm from

the STAR SPRINKLER Corp. Not sure this is the forum for this, but, I always thought water motors were a neat invention, and never had a chance to get one. Then one day after many, many years of casual looking :uhoh: for one, more than one was found the next town over :p . I made the call, went and looked in the rain, and bought them all :eek: , including any parts and pieces at this undisclosed location. Here is a STAR, I assembled the other day and is the start of a (NEW), water motor collection :shrug: . Are there any other collectors of these around? What can I say, it has a motor, and does something :O . Just having "FUN" even in NJ on the way through :O .

I've got a water motor. I'll add details and a photo later.

I suspect that the sprinkler alarm is piped into the flow of the sprinkler system and when flow is activated at the sprinklers, the flow turns the water motor that turns the alarm bells.

Our church just replaced a water motor/gong on the fire suppression system. Code requires the gong but the new one will be "electric" with a seal-in relay.

I'm on the Building Committee. I'll have to check and see what they did with the old water gong?

I am a retired Sprinkler fitter. Harry is right when the water starts to flow a special valve called alarm valve opens and send water pressure to the water motor alarm.
I have a 1907 Grinnell water motor alarm bell which I have connected to a small cistern pump powered by a WMB briggs. It rings the 16" bell real loud. It can be herd for 3 blocks This unit is very ornate. I will try to get some pics here on this site. I have problems trying to figure out how to do this. later Arlie

a diagram of a Grinell type alarm.
the heavy washer (striker ring in the cross section) on the end of the shaft has an oversize hole
so when the shaft spins, the washer hits the inside of the bell.

When I worked in construction, I used to go to the demo areas and retrieve the wrecked water flow alarm bells. I had 4 or 5 of them at one time. On one site (an old mill), I even found a water powered sump pump! I had mounted the fire alarms on a mount and circulated water to run them. The sump pump returned the water to the holding tank as well. Over the years, I have sold all the alarms and the water pump that drove them:(

One respondent encouraged me to go after this gong. At last inspection (Sunday) the electric gong is in place, and so is the water gong, seemingly left because it covers a hole in the concrete foundation.

It may be there a while.

The weeks & months sure have passed quickly, and I got a call saying he had another (different) one for me. Come on over and check it out :brows: . The next day I made the call, and 30 minutes later I had another one :p in the back of the Chevy 1500 with 490,xxx miles on it :yikes: . Here are a few photos of it (could only add 4 ?) when I got it home, taken all apart and cleaned up. I put some air to it and it does motor and rings the bell ;) . Now where is my B & S pump outfit :confused: so I can make up a static display showing how the “SPRINKLER” fire alarm systems work. I can hardly wait to fabricate something :D (not another project). As a matter of fact, maybe its time to drag out my 1HP IHC Titan pump outfit with the Myers pump for the supply, but that would probably not work to well :shrug: . Still, having "FUN" even in NJ on the way through :salute: .

Wow, how did I miss this thread? Those are COOL! :D I have always liked them, but never seen one up close. Thanks for sharing!

The Pelton wheel pictured :uhoh: in this sprinkler alarm is small @ 4 1/2" and is an interesting design :uhoh: . One of these days I'll have to hook it up to a water supply and get a video of it ringing :crazy: just for "fun". Here is another picture before cleaning, and
a link to more Pelton Wheel information for those who want to know more, I still do :p . http://www.oldpelton.net/

One of these days, became later today ;) as I got to thinking, I have someplace in my “pipe” stash, a pipe the right size with a female hose connection on one end. Well a few minutes later :uhoh: I found it, got busy, made the pipe connection to the water motor, hooked up the outdoor hose, slowly turned on the water, and away it went “RINGING” :yikes: on low pressure and then louder with a bit more. I didn’t apply full house pressure because it would get quite loud. Here is a short video of it in operation without any leaks :rolleyes: , except for the water exhaust :p . Boy am I having “FUN”, even in NJ on the way through :brows: .

Neat! BTW, in the link you sent, the first photo, of the Pelton wheel driving the air compressor, I have one that for all the world looks identical to it. I do not have the nozzle for it though. I assume they made governors for these too? With a variable nozzle? Always wanted to put together a small private hydro electric plant. :D Need to buy some property with a waterfall.. :shrug:

Hmm, That makes two of us Keith. I want to experiment with hydro power too someday.

I don't think you have to have a waterfall though. Just a good flowing source of water and some drop in elevation. Even a small turbine can be made, Something like this I suppose to increase the RPM or decrease RPM if need to be. https://www.youtube.com/watch?v=0co0aUmBKZ4 I got the idea in my head to drive a large 24v truck alternator on something like this.

Friday, I got a text message with photos from my “SPRINKLER” guy asking if I was interested in another sprinkler alarm with a small water motor :bonk: . I said I’ll met you at your place at 5:00pm. I arrived early, waited a bit, bought the RELIABLE Type C on the spot. I told him, “YES” I’m interested in more from time to time as he gets them. Took it home and began fussing with the new toy right away. It had a few issues from removal from the building, but with a little machine work it was all OK. Then there was the debris build up from the standing water in the system and pipe threads. I also need to fabricate a “FAKE” building wall of sorts to hold the parts together. After I got everything cleaned up and operational, I tackled the “FAKE” building wall. I thought about building a model wall, but after thinking about it for a while :idea: , I went out back and found just what I needed, a piece of 2” PVC pipe in the “save for future use-someday-PILE”. Then I cut off an appropriate length that would give me what I needed to hold the parts together. A little work with getting the dimensions right, a bandsaw and file, and it’s done :p . Yes, it alarms nicely and has been put in the “PILE” collection of sprinkler water motor alarms. Still having “FUN”, even in NJ :uhoh: on the way through. Well, off to the - NEXT project.. :)
