A thread guide is a tool to measure the number and pitch of threads on a bolt
The thread guide keeps the thread going straight in one direction.
Take the thread through the first thread guide which is on the right, then through the needle guide notch. Wind the thread around the tension dial and pull up to the left of the dial. Pull the thread into the thread guide at the bottom. Take the thread from front to back through the needle eye.
Yarn guide / Wire guide
The thread guide keeps the thread running in the proper place. If the thread is not threaded correctly, the tension will be off, resulting in jammed or broken threads in the machine.On a sewing machine, the thread guide is a small part that is attached above the needle. It looks like a hook and it hold the thread in place as it is fed through the needle.
The thread must come from the FRONT of the upright spool on the back of the machine. Thread through the small eyelet on the back (nearest the spool(s), projecting from the top), then through the thread guide at the front of the machine. If you are using a double needle (therefore two spools of thread), the thread from the left-hand spool should go through the top hole and the thread from the right-hand spool through the bottom hole. Come down to the tension disks. Bring the thread through the back disk, up again under the wire guide, and down under the thread guide that is just to the left of the tension disks. Bring the thread through the eye of the take-up lever (the piece that moves up and down when you sew) from RIGHT to LEFT. Guide the thread back down through the thread guide next to the tensioner. There is a little thread guide just inside the door on the left side of the machine; bring the thread through this guide. Then pull the thread through the wire guide above the needle (it's easiest to hold the thread horizontally to do this). Thread the needle front to back. HTH. YMMV.

The upper thread guide on a sewing machine is the markings on a sewing machine which show you how to thread the machine. It's usually indicated with arrows, dashes, and numbers, giving you step by step guides to thread the sewing machine properly.
Thread guides lead the thread in this order: Thread Spool to Tension Discs to Take-Up Lever to Needle. A machine is threaded with the take-up lever in its highest position and the presser bar lifted. Generally, the thread guides provide a path that keeps the thread from crossing over itself. From the spool, any thread guides mounted on the top cover are first, back to front. On the face plate (front of machine) any thread guides that sit to the right of the tension discs are threaded before inserting thread around & between the discs. If there be any thread guide that is BOTH to the left of the tension discs AND right of the take up lever, the thread would go there next. My fairly typical Japanese Zigzag Machine does not have a thread guide between the tension discs and the take-up lever, but if there were one, I would call it the "Tension to Take-Up Lever Thread Guide." From there the thread passes right-to left through the hole of the take up lever, and then down through all thread guides mounted to the left of the take-up lever. Lastly, the thread goes down through a needle clamp thread guide and through the eye of the needle. Not a short answer, but I hope it addresses your question.
Yes, there are guides available, one being http://www.notebookforums.com/forum/thread/207013/definitive-thread-guide-to-laptop-stands-for-17-laptops.
To thread a model 117 959 sewing machine, first, raise the presser foot to release tension on the thread. Place the spool of thread on the spool pin and guide it through the thread guide, then around the tension discs, and down through the take-up lever. Next, thread through the needle from front to back, and finally, pull the thread under the presser foot. Make sure to leave a tail of a few inches for proper sewing.
