Top is overhead view, side view is shown at below of teetter- totter, or seesaw action motor.
Toward each end, 50 turns of #18 bell wire (shown as 1 nh coils) around top line which is (metal rod with center pivot point, shown as upside down ground) and winding coils close to each end of horizontal rod and then connected to batteries on opposite side, with one battery terminal only making contact when pivot rod is down.
Side construction view shown at bottom. Vertical SPST switches is vertical iron rods which can be attached to outer sides of dry cells a little above battery tops.
How it operates. One side and contact terminal is pushed down which makes electromagnet of coil on opposite side to pulls down toward vertical iron rod. As horizontal pivot rod comes down contact is made with battery on that side to make electromagnet on other side and the seesaw of battery contact and attraction of opposite rods continues. Adjust vertical rods, battery contacts, and battery voltage to sustain motor seesaw action.
