Made before McGraw-Edison purchased Bersted Electric Company in 1957. This fan has a medium gray hammered finish with a fast moving 8 inch diameter aluminum blade that sounds much like a prop airplane. Didn't come with a switch originally, but now it has one installed inline on the electric cord. The chrome plating on the cage is near perfect and shows no sign it ever had any corrosion.
A super blow up of the front badge. The magnification makes the badge look rough, but it is not. All of the lettering is intact. At normal viewing distance the badge is very smooth and shiny. It has been attached loosely for easy removal and doesn't rattle when the fan is operating.
Originally, the blade was held on with a hex nut with an aluminum cone that had tabs that fit into the narrow slots near the center of the blade. When you remove the cone the tabs will most likely break. The acorn nut seen here is a good alternative to the original hex nut.
The hardware had no corrosion in its original unrestored state and has been cleaned and polished. A tiny amount of mineral oil has also been rubbed on the pieces in order to protect them from future corrosion. The black hole above the center shaft is for oiling the rotor and should have three drops added for every season of use. This includes to back of motor hole labeled "OIL".
The hole in the back of the base is for hanging the fan on a wall.
The original stabilizing feet have been replaced with hard rubber plumbling washers. Notice that the inside of the rivets that hold them on have been painted. The other side of the rivets have been polished and clear coated with lacquer.
The plug is rubber with a hard plastic center the holds the polished blades. Has a rubber grommet inserted into the plug to help hold the cord tight.
Original motor windings after peeling off the corroded insulating tape that kept the windings together. Unserviced, the windings will bend and flex as the motor runs and eventually cause an electrical short that will damage the motor permanently.
In order to service the unit the rear cone needs to be removed in order to remove the nuts that not only hold the cage on, but the motor assembly too.
Front side of the stator after reinsulation.
Back side of the stator after reinsulation. The wires connect through the back side of the fan where the cone resides.
Polished rotor with rubber spacer and washers needed to place the rotor exactly where it needs to be within the stator's magnetic field.
Bearings that fit into motor housing are in excellent condition. The odd shaped piece on the left is used as an oil guide.
Bersted Zero Single Speed Model Model 1250R, Circa 1956
A collection of images from a restored vintage electric fan. Has a high speed 2 pole motor and light aluminum blade that spins up to 3600 r.p.m. (assuming no load or asynchronous induction slip). The effective range for this fan is 2-8 feet and is perfect as a desktop fan.
An inexpensive "drug store" fan that was made as a cheap alternative to more feature filled, higher quality electric fans. Built with planned obsolescence in mind, this low quality fan of its time is actually considered to be of high quality today. Probably only cost $8 in the mid 1950's. Not a collector's item, but one of the few fans that is easy to work on and still very affordable in good condition.
