Question about Singer Sewing Machines

1 Answer

I have a basically brand new Singer . 4525. (Never used by original owner) It is a marvelous smooth running machine but 2 issues have arisen after 20 hrs run time. #1 the thread starts bird nesting in the middle of a seam and there is no discernable change. It will sew beautifully, bird nest, then sew beautifully again and I don't find until I pull the piece out of the machine. #2 (the worst) it was sewing along smoothly, I put a new piece in and the machine vould not complete it's stroke. Foot plate off a needle is bottoming out in the bobbin casing???

Clean the bobbin housing for any dirt. Check the tension of upper thread whether correctly set or not. May be this is time for servicing.

I have fixed it now the bobbin case didn't seem to stay seated during sewing or tangling i should say!. I decided to change the needle and from then on everything worked fine.

Needle could be loose or bended or use another size. Put the needle all the way out and the insert a new one inside making sure is the right way in (flat part hasto be looking oposite of you).

another thing is that the Tension could be too tight.

Last, Rethread the machine with another thread to make sure is good.

Hope it helps

SOURCE: Needle thread looping underneath, threads not interlocking at all

If the machine is now threaded, lift the presser foot.

Now, pull about 10" of thread through the needle.

The next time you thread the machine, lift the presser foot first.

When the presser foot is up, the tension control opens and allows the thread to "seat" into the control, then when the foot is down the control closes to the indicated setting.

When threading the machine with the foot is down, thread does not enter the tension control and when you start to sew, there is no tension on the thread.

No tension = loosey, goosey, loopy stitches underneath.

Because the lack of tension on the top thread, the bobbin thread cannot lock a proper stitch.

i think you have something catch on the tension guides. Try to clean out anything you can see and pull a thread towards the needle. I have done this with a small knot to snare anything but be gentle. Also, rethread carefully.
Try cleaning the bobbin case too

Assembly instructions for Singer Merritt 4525

The service manual for that machine can probably show you, and I would make sure and get the parts list as well. I just checked Sewing Parts Online, and it was not listed, but if you send an email to them (they give the address at the top of the page), they can and will purchase it for you. Usually takes about 2 weeks. However, I just saw a used one in nice shape on eBay for $72.99 and $27 shipping in the original box, so you might consider just buying another one. I also noticed that a new tension assembly is being sold for $18.95 including shipping, and if you write to them, they may include replacement instructions. Just do a search on Singer 4525 on ebay--they have all kinds of bobbins, foot pedals, and parts for it.

Antique Singer Sewing Machine AE993349. Looks

You have a model 221 which was made on May 24, 1938 at the Elizabethport factory in Elizabethport, New Jersey. There were 20,000 of those made during that particular run which may have been over a few days.

Its value depends on its overall condition and what someone is willing to pay for it. Sight unseen, I would estimate market value for that machine in good running order at between $250 and $400.
