Need a sewing manual

Threading a UHT J 1947 sewing machine is a relatively simple process that can be broken down into a few basic steps:

1. Raise the presser foot lever and thread the machine according to the diagram on the machine.
2. Wind the bobbin according to the instructions in the manual.
3. Place the bobbin in the bobbin case.
4. Draw up the bobbin thread by turning the hand wheel towards you.
5. Hold the end of the bobbin thread and press the foot control to raise the needle to its highest point.
6. Thread the needle according to the threading diagram on the machine.
7. Lower the presser foot, and you are ready to sew.

It is important to consult the user manual of your specific UHT J 1947 sewing machine to get the most accurate instructions, as the threading process may vary depending on the machine's model and design.

Hm, I'm not able to locate a manual but may be able to offer some suggestions.

Remove the top thread from the machine.
AVOID OLD OR BARGAIN BIN THREAD!
Use the same thread in top and bobbin.
Be sure to use a brand new needle--needs to be compatible with the thread and fabric of the project..
ALWAYS RAISE the presser foot and rethread from the beginning.
Set the top tension to the midway point.
Verify the bobbin is loaded and threaded correctly and it turns the correct direction.
Pull the bobbin thread up through the fabric before taking the first stitch. It also helps to hold both thread tails in your left hand when taking the first stitches.
Test your machine and tweak the top tension until the top and bobbin threads meet in the middle of the fabric. (Increased top tension will pull the bobbin thread up. Decreased top tension will allow the bobbin thread to pull the top thread down.)

Sears carries manuals for most of their machines (usually for free). The manual is invaluable for using your machine, including threading instructions.


Kenmore 158 1792 Sewing Machine Threading Diagram

If you need a manual, search the internet for:

Make + Model + the word "Manual"

or contact the manufacturer.

Try installing a brand new needle. A bent needle sometimes will not connect properly. Be sure that both upper and bobbin threads are threaded correctly.

On the other hand, the needle/hook could be out of time. You can check that by hand turning the handwheel and watching the needle/hook movement. There are a multitude of web sites and videos that discuss timing. Or--check with a sewing machine technician.

...

Check the model number of the machine. White sewing machine manuals are available from Singer at http://www.singerco.com/accessories/instruction-manuals . Enter the model number and click Search.

The White Sew E-Z model W338 manual is available here: http://www.singerco.com/uploads/download/705_white-338-x.pdf .

Unlike some machines this one doesn't really need the bobbin threaded. Place the bobbin in the bobbin holder and leave about 5" of thread extended out from the bobbin holder. With the bobbin compartment still open, lower the presser foot and turn the handwheel to move the threaded needle through the stitch cycle. (I find holding the threads helps; normally, you'll feel them pulling under your fingers.) When the needle has returned to the top of the path, lift the presser foot. Then pull both threads around to the front (the bobbin thread should wrap around the top thread). Then move the threads to the back of the presser foot.

If the needle isn't catching the bobbin thread, first try a new needle (bent or dull needles don't always function properly). Next check the bobbin holder for nicks or other damage. There is a small hook on the bobbin holder that should be where the top and bottom threads intertwine. Under rare circumstances, you will find that the bobbin tension of the bobbin holder is misadjusted. This can interfere with the bobbin thread twisting properly. There is a little set screw that allows you can tighten or loosen the bobbin tension as needed. Adjusting the screw is to be avoided when possible and done in small increments (1/8 turn) if needed. It's easy to strip the threads for the set screw and end up needing to replace the bobbin holder.

I hope this helps.

I could not find any reference material for this model.

But, Singer has examples and instructions for both a drop in bobbin and a rotary (side/front) bobbin.

Hope this helps.

This is for a front loading bobbin

You have not mentioned the machine or model, so if this is not like yours, it will be a top loading or drop-in bobbin.

In either event, the idea is to pass the thread thru a small slot and thereby between a tensioning spring......your Instruction manual will have details for your model, tho' with a little thought, any manual for a similar machine (top or front loading) should give you the basic idea.

If you still have troubles, let us know the make & model.
