Gasgoine Miracle Milker

Is there anyone on here other than me that remembers the old Gascoigne Miracle Milker ?

I am restoring one and so far I have got the pump, tank pressure relief valve all working.
It will hold vacum and if I block the hole in the bucket lid with my thumb it will empty a bucket of water but I cannot get the pulseator working and cannot figure out how the pulseator functions.

I assume it is the contact with the cows udder that creates a seal and thus a vacum that transfers to the pulsator and what I am not getting just pumping water.

As there is only one pipe to the pulsator I am guessing (please correct me if I am wrong) that there should be vacuum from the claw to the pulsator.
I have removed the pipe and checked for vacuum with the valve in the claw both opened and closed with no effect so I am guessing it could be a leak inside the claw ?

Are you talking about those Gascoigne bucket units that used the Positive pulsator, or something more obscure?

Has anyone got a diagram of how the old bucket milkers were piped up.

I assume that there are 2 vac input pipes one direct to the Bucket 1/2" and a second 1/4 to the pulsator

I think the pulsator got it's vacuum by sitting on the centre hole on the bucket lid. If I am thinking of the correct set up. The 2 1/4 pipes out let from the pulsator go to the claw.

Yes I will get some photos up later today.
I have both types of Gascoinge Pulsator the Positive & Ratiomatic
Neither bucket lid has an outlet for a 1/4" vacuum connection, so I will add a 1/4" barb to the pipework and run a line down to the pulsator.

Normally only one 1/2 inch vaccum pipe to the bucket.
A small 1/4 pipe would then go from bucket inlet to the pulsator.
From the bucket to the claw is a 1/2 inch pipe and from pulsator to claw is a1/4 pipe.
It is possible you have not got the pulsator pipes correct, however all pulsators were notoriously sensitive.
I am not sure that I ever worked with the Gascoigne version so I may be wrong, there were some milking machines used a pulsatorless system.

Thanks guys I will add photos later.
This is the first Gascoigne setup I have worked on.
We had all alfa laval stuff and I could service one of those pulsators blindfold after the amount I did from age 10 (oh such cheap labour)

looking at the top picture and may be wrong.
large pipe on left is vacuum feed from supply. This would have a splitter with a small quarter feed going to the pulsator.
I rather think the top pipe is vacuum feed on pulsator with a twin pulse feed to the cluster off the bottom pair .
The pipe on the right is the vacuum to the cluster.
The bottom picture has a single pulse feed to the cluster which Fullwood owners were used to.
Different claws of course.
