Digging through my rusty stuff I came across this intake manifold that has been tapped and had an elbow screwed in.. I'm guessing that it was probably to operate a vacuum tank.. but I'm a bit confused by the long device, about 3 inches long x 5/8 diameter and perforated with tiny holes.
It appears to me to be a Relief Valve? Maybe to protect the devices using engine vacuum. It will have a spring loaded seat inside and an adjustable screw. Just maintains a maximum level of vacuum in the system
Reminds me of my "Carburaid", a device with a ball in it that rises under increasing vacuum, resulting in a leaner mixture.
Wolf whistle? I know some of them did attach to the intake manifold, but I do not really know what they look like as I don't like them. I don't like explosion whistles either, but that is just me. Lots of people love them.
Drive carefully, and enjoy, W2
Thanks for the replies.. relief valve seems the most likely.. I'm making up a bit of a display in what is becoming known as "the T Room" by the family... for Father's Day my kids even had a sign laser cut to that effect for me to put up over the door... so I'll include it in the "museum" and see if someone else can confirm ..
In the mean time here is another thing I found. It may not even be T related, but its in a box of T bits. If I had to guess I'd say its part of an air cleaner, but happy to stand corrected. As a Aussie Down under I'm not especially familiar with US of A manufacturers and the name may mean something to the good citizens of US.
Tony, The device on your manifold is an "extra air" unit.
Lots of these were sold especially in Australia to supposedly give you better fuel economy. It can be hard to find an inlet manifold with out one.
There would have been most likely a cable connected to a lever on the dash or steering column which allowed the driver to open it to allow extra air be added to the mix.
The Gabriel Snubber is a type of shock absorber, it consists of a drum with a woven belt which attached to your axle with the drum attached to the chassis to help axle bounce. Someone should be able to show you an advertisement for them from and old magazine.
Peter is right, I have one on my car, it has a brass piston inside it and when it is moved backwards or forwards it opens up extra or less holes. It is connected by a cable to a nickel plated lever mounted vertically on the steering column
Tony: There is a spring inside this piece with webbing attached that rolls up inside. Without seeing the back of the item I am guessing it mounts on one side of the frame and to the rear axle to act as a "snubber" to prevent too much rebound of the axle. There should be another one on opposite frame. Other accessory snubbers mounted on the centers of the frame front and rear and attach to the front and rear axles. I have a set of front and rear on my 27 touring.
Well another mystery solved... there are so many interesting variations to investigate. Thanks for the replies.
Tim, all I have of the Snubber is the case you see in the picture,( you can actually see my hand inside it through one of the 3 holes) which is why I thought it might just be the "lid" or cap of a cylindrical item such as an air cleaner. Another interesting bit of motoring history.
here is an ad for the Gabriel Snubbbers
Thanks for that Peter... I just went to the monthly meeting of the local Antique car club, and lo and behold, there on one member's latest acquisition, a '27 Willys Knight, was a set of these ( or possibly re-productions) clearly visible on the front axle/chassis. From not knowing anything about them to seeing a functioning set in 24 hours!!!! Amazing.
