Here is a Hamilton-Beach motor and controller found on a 1919 Singer 115.  It has a Singer mount, that attaches at typical Singer motor/hand crank boss.   The cast iron mount has a cast in "S".  I do not think it was a Singer part, but an accessory from H-B.

The motor has an interesting feature for easy change of motor rotation direction.  There is one screw near shaft at 1 o'clock in picture, removing it, then rotate brush assemble in slot to other end, replace screw.  There are contacts inside, when brush assembly is moved to other internal connection, the polarity changes.  This feature was important. Using motor with rollers on hand wheel,  rotation is different using with belt drive.  H-B also wanted the motor to be universal in house use for other appliances.  The motor sits on a pin mount, so it can be easily lifted off, for use on another appliance.

The motor runs smooth, and powerful.  I think it may be a bit big for a Singer 115.

The foot controller is similar to the step of resistors used in early Singer Bentwood case, and in foot controls.  The resistors are in the round part above the pedal.  There is a ceramic disk, with grooves, where wound resistors are connected to terminals.  There is a wiper contact that rotates by a linkage  with pull of pedal, to select resistors.

Those motors were also sold by H-B as the "Home Motor" -- it had a little base, and pulley and friction drive, and you were meant to use it to power just about anything you could connect it to, including treadle machines.  They were also rebadged -- Western Electric used one on their National rebadge, and advertised it as the world's first electric sewing machine. Which it wasn't, but hey, marketing.  Pictures of mine here: https://projects.foxharp.net/sewing_machines/#c1918-western-electric-no-2-portable

My first motor was burned out -- both field and armature -- but I found another on ebay and swapped some parts around.  Shaft was bent, but managed to straighten it well enough.

I've also seen a 66 with that motor, badged as Singer.  They also show up on New Homes, and lots of others.

Paul,

Thank you for the information. I wondered if Singer brand brand labeled them, know I know.

I have converted machine to handcrank, and may sell the motor and controller.

I confess I was pretty surprised to see that Singer had badged the motor.  But it was a very early mass-produced motor, and maybe they didn't quite have their in-house act together yet.  And they certainly wouldn't have wanted to miss out on the beginning of the electric market.  The machine I saw was from 1919.  I went back and found the posting on FB, partly because I wanted the pictures to end up on this site somewhere.

Paul,
Thank you for sharing again. I have a few 1922 Singer 99k with BT7 motors and controllers. I have tried to find info on BT7 release, Google search not helpful. I think you are on target about brand of H-B, to buy time. They were likely developing Singer 101, and had hands full.
