Saving historical relics, even items as mundane as antique incubators, can lead one down interesting paths. So, come along and learn about an interesting farm "tool" of the early 20th century. Way back when, "egg money" was used to buy staple items: Salt, sugar, coffee, flour and the like. First, though, came the eggs, then the chickens, then the eggs again. To avoid a debate here, let us go on to incubators. After all, where are you going to find a setting hen big enough to handle 100 to 400 eggs? 

First of all, eggs were candled: That is, candled eggs were passed in front of a small hole in a box with a light bulb or candle behind it. The fertile eggs would be kept; the non-fertile ones sold, or eaten.

Incubator manufacturers were numerous, as is shown in the Spring issues of the 1911 Farmer and Breeder, a weekly out of Sioux City, Iowa. Cyphers Incubator Co. was urging farmers to get into the $1 billion-a-year poultry business (Not giving a time frame for the billion dollars, though ... ) "Old Trusty" would come to you for less than $10, along with a 10-year guarantee. $7.55 would buy a Belle City Incubator out of Racine, Wis. The X-Ray, Wayne, Neb., was another, followed by the Ray O from Blair, Neb.

Antique incubators were handsomely finished, often built with redwood, and could sit inside nicely. A small boiler containing a few quarts of water was heated with kerosene. The heated water was piped around inside the box through pipe or tubing. Smaller units saw eggs turned by hand; in larger units, moveable grids allowed easy turning of the eggs. Interestingly enough, these old, primitive, outdated, low-tech units were capable of maintaining correct incubation temperatures (102-103 degrees) for up to three weeks, and all that was accomplished without any chips, transistors, or solid state relays. Here one is reminded of the space shuttle, which routinely launches a few weeks late. Isn't technology wonderful?



The large, 400-egg Charters unit was manufactured in Santa Cruz, Calif. How it wound up in southeastern South Dakota is anyone's guess. This unit employed a bellows-type thermostat, controlling a shutter on the kerosene burner to either raise or lower the box temperature. This unit also has a tray to hold water, maintaining correct humidity. Grids were used to turn the eggs.

From Springfield, Ohio, came the Buckeye No. 1, a rather primitive 100-egg unit. Eggs were turned by hand, and humidity was also controlled manually, probably by sprinkling water over the eggs. The temperature is controlled with an "X" shaped steel thermostat on an adjustable rod. That, in turn, is hooked to a long, counter-weighted rod acting on a "hat." The hat moved up and down in response to heat in the box. As the box cooled, the hat dropped down over the boiler exhaust, causing it to warm the water more.

Underwriters laboratories was the group of safety engineers that ensured that WHOEVER built your incubator was doing so, - safely. It sounds like you, like I,- have a very old Monkey Wards hatcher/incubator. Mine still works, I just replace the thermostatic wafer at the switch, which regulates the electrical induction into the nichrome wire bundle that heats the unit to a perfect -101+ and hatches the eggs inside. If you need more information, check your brass tag on the bottom and see who made it. If you can't find it or its been removed, submit a photo so we can see it. Someone out here will recognize the unit.
