I have an Interlock Machine. These are the words on the front of it:

Differential Feed
MYLOCK 1340
JANOME

I need a foot (or feet) for it for regular sewing and for quilting. Would anyone be able to tell me the correct name and where I might be able to purchase them?
Thank you!

I've got all kinds of feet, but have no idea what they can be used on.

Go to Ebay those sellers will help you.

Research feet on the Janome website. Then Google for the foot you like.

I am sorta new (and new here also) to quilting with all the new gadgets,rulers etc,
I have 3 machines, a New Home I bought in 1970, and didn't think I would ever buy another,( ha ha) , it has the screw on feet, and some feet, in the last 8-9 months I have bought Singer Desinger? and bought tons of feet to go with it, it has snap on feet.... It is light weight and would do to take traveling, has lots of stitches... then last month I bit the bullet and bought a Jamome Hirozion 7700, it came with a ton of feet and the extension table, and the knee lift, which I have not taken out of the box, I am wondering if I can use some of the Singer snap on feet the Janome?

If they are both made for low shank you can use them interchangably.

I would try here, http://brubakerssewing.com/ They're very helpful people.

It sounds like the machine you have is a serger, not a regular sewing machine. If this is true, there is not a foot for quilting and sewing. It will use 2, 3 or 4 threads for sewing an overlock stitch, such as used on knits or finishing edges. You can piece something simple with it, like blocks, but you can't quilt on it. It would make for thick seams serging them, too, because of all the threads.

And are you sure this isn't a 134D, not 1340. If it is, then it is definitely a serger.

It could be a 134D. My eyesight isn't that good except for sewing straight seams. It is a serger, I thank you very much for the information you gave me.
