Domestic Electric Sewing Machine

HELP: We need a manual and bobbin winder for this machine.

A door behind the motor is removed for lubrication.

Domestic Sewing Machine Motor

The above image shows the attractive motor on the machine. Note that the motor has its own serial number.

There does not appear a way to adjust the conical rubber motor-drive wheel. After loosening a small retaining screw, the wheel can be slid back and forth until it contacts the handwheel. With this setup, when the smaller part of the cone contacts the wheel, the motor turns more revolutions for one rotation of the handwheel than would be required if the cone were in contact on its larger side.

The motor has lubricating cups on either side. To speed up the restoration process, we removed the cups and applied small amount of oil directly into the hole. The cups contain a fiber which apparently allows only a slow amount of oil to enter the motor bearing surface. This is probably done to prevent the motor from slinging oil over electrical components. Seen on top and bottom right-hand side of the motor are caps for removing the brushes.

We have not learned how to thread this machine. Not only is the threading pattern a mystery, but the tension adjustment has us baffled. We only hope we are not missing any more parts. Lubricating this machine is something else. To lubricate the needle bar and pressure foot, the entire faceplates is removed. When it is removed, along comes the presser foot and needle bar--they don't stay in place like our other machines. Reassembly is tricky as a bearing must be engaged blind. Also, after the faceplate is reattached, the needle must be checked to ensure its travel has not been disturbed.

The spoke handwheel is a nice touch. it can be disconnected from the machine gears by flipping a small lever on the outside. On the inside is a groove if it is desired to use the machine as a treadle.

Our machine came without a foot controller. A problem is that most adapters available nowadays are of the typical 2-prong 110-volt house receptacle. What we have to do is convert this plug to that configuration. We would like to preserve this connector so we will be trying to come up with a way to connect our new controller to this plug.
