In this picture of electric machines are displayed a group of antique dynamos and motors in miniature dating back to the 1880's. Some of them might be classed as toys in their day and are things of the past now, Knapp, Ken-drick & Davis, Ajax, Volt-Amp, etc. Also this collection contains types that were used in the field of service, some of which I modeled after Edison's early type lighting dynamos used in his first electric light plant in New York City. Carbon filament lamps were used in those days for lighting and resembled a redhot hair pin in a bottle. This type I use in my lighting layout and are also things of the past. First in line (left) is an old Auto-Sparker once used on an old sawmill single cylinder large flywheel type gasoline engine, to furnish electric current for the make and break ignition system. This was friction driven from the big flywheel of the engine through a pressure controlled fibre pulley on the shaft of the Auto-Sparker regulating the speed of it and was adjustable by a thumb nut on the governor arm. An interesting note is that back in about 1907 I hooked this same machine on to my uncles' Peerless steam thresher engine, and I'll bet that was the first electrically lighted steam thresher engine. I had it fastened to the belt guide roller bracket in front of the engine flywheel and drove it by the friction pulley against the surface of the flywheel and regulated the speed of the Auto-Sparker by its pressure governor so as to give the correct voltage for the lamps we used in the head light, the water and steam gauges as well as a light under the canopy. Next in line is a model A Ford early type (power house) auto generator and is a real work horse. These generators can be easily converted into a 300 watt 110 volt AC generator. Also the early Dodge 12 volt motor-generator can be so used and when properly rewound will furnish 1000 watts 110 volt AC which is plenty for a small plant for emergency lighting when driven by a 2? HP engine. The next in line is A Robbins & Meyers 32 volt DC 500 Watt generator made from a motor and is used to furnish DC to my army-navy surplus radio communications Amateur radio equipment. The second in line is a small 6 volt motor, a toy driven by dry cells. The next is a model of an early Edison bipolar 12 volt motor made by me. The next is magneto type generator made from an old Williams Telephone Supply Co. ringer generator by rewinding the armature and was used as a lighting generator.

Next in line is an old Bosch lighting dynamo which was used for lighting on the Stewart trucks in the real early days of the auto. It was 12 volts and was so wound to produce constant out-put. It makes an excellent battery charger unit. Next in line is a larger Bipolar Edison motor having been changed into a dynamo and will deliver 500 watts at 110 volts DC with good regulation. The one in third row forefront is small turbo-generator steam driven and will furnish 1.5 volts at 1.5 amperes AC to around 10000 RPM. It has a rotating magnetic field of a permanent magnet whirling between a two pole stator by a turbine impeller at a high rate of speed and sure will burn out flash light bulbs as fast as you can replace them if the speed is not controlled properly. This little turbine-generator I built up for furnishing electricity for the head light on one of my live steam 1? scale locomotives, a Baldwin 4-4-0 of 1907 vintage and was used on the old. Huntingdon & Broadtop R. R. as passenger engine number 30. Next in line is an Ajax toy motor which I got in kit form and put it together, armature winding and all when I was still in grade school.

53121 Wallis 20-30 - Certified - manufactured in Racine, Wisconsin about 1930. I have about 150 gas engines from 1 H.P. to 20 H.P. - years 1892 to 1939 - all makes and 15 tractors - years 1912 to 1931 - various makes and sizes.

Next in line is a 2 phase 32 volt AC generator which I made from some war army and navy surplus equipment. It will light 12 4cp lamps fine.

The next one is a small Western Electric 1/30 HP DC. motor which is combined, series and shunt wound type. I use it as a load for other dynamos. The last in line is a model of an old 1893 Westinghouse dynamo used as a lighting source of electric power. It will only develop about 35 to 45 watts at 6 volts.
