Has anyone used a vacuum ball or reserve tank. It seems like it would help with the wipers stalling out when you are accelerating. I have never seen one used on a Model T. Ford had a nice small round plastic ball on some 70s 80s vintage cars that would hide behind dash on starter cars. Thanks Donnie ....
Vacuum tanks with two chambers and poppet valves were used to pump gas from rear mounted gas tank to high up on the firewall where it drained by gravity to the carburetor. Many of these cars had vacuum windshield wiper motors, but were separate from the fuel system. Vacuum lines to the wiper were very small. Why don't you build one with a tin can and a check valve and see how it works?
Does not sound like he need to build one. Sure why not give it a try and see what happens.
Donnie, I've been thinking along the same lines as you. Trouble is finding cars that old in wrecking yards to get them from. If you find a source of new or used, let me know.
They're easy to make.
Easy to build but you won't get what you want. They were used on cars years ago with unsatisfactory results. Dual acting fuel pumps were used too. Electric wipers killed them all off.
The best arrangement I know is to make the tank with one connection, take the vacuum line from the engine and add a spring loaded check valve so air can only go towards the engine. T the tank into the line between the valve and the wiper. This gives you a reserve amount of vacuum whenever the engine vacuum cannot open the check valve.
Another option is to make a spring loaded bellows instead of a tank, but that needs to be somewhere where it won't get damaged, and is free to open and close.
The Anglia 8 &10hp cars used them and I found it worked well. Only defeated by very long hills. Virtually the same tank wa used on Jags for the brake servo. Google 'jaguar vacuum tank' and you will parts dealers offering tank & valve for models as lste as XJS. On UK ebay I found an XKE one for 15 quid, also a tank off a 2008 Ranger, don't know what that is used for or what size it is. But basically , no need to waste time and effort making one.
Ford / Lincoln / Mercury / Thunderbird made many cars with vacuum headlight doors in the 1960's - 1980's. They each have a huge vacuum canister for the headlights, about 10" by 8" by 16". One of those tanks could be mounted in between the frame and the drive shaft for a super vacuum reserve.
Smaller vacuum tanks for vacuum operated tilt - away steering and air conditioning systems are found on many other Ford / Lincoln / Mercury / Thunderbird models. You can find them in a wide variety of shapes and sizes.
Donnie, Do a search on Ebaymotors for 'vacuum tank ball'. It will bring up several choices. I bought a vacuum ball from a seller in Longview, Texas, not just because he was in state, but his parts were new and it has a built in check valve.
Late 70's era Ford Falcons and Fairlanes had them fitted to the Air Conditioned cars to stop the air moving between the dash and windscreen when accellerating. I fitted quite a few when working for a dealership as a mechanic. Most were fitted under warranty to stop the problem with the AC. Looked like a large jam tin with a valve assembly in one end and a bracket attached to fit to the left front inner guard.
Granada had the same thing Pete. Looked like a quart juice can mounted between the left fender and the fender wall. A real bb to change. They usually rusted out on top because water sat on the lid.
There were several can type on Ebay that the seller claimed to be from a 1973 Mustang, but I opted for the plastic ball,. It may not hold as much vacuum, but it won't rust and will fit under the dash and cowl.
