Wheat Lamp Charger

This is a Model 585 Wheat Lamp charger that was made by the Koehler Manufacturing Company of Marlborough, Massachusetts during the 1930s. Grant Wheat’s electric cap lamp would need to be recharged after about 12 hours of work. While large commercial mining operations would have used large charging racks to power their Wheat lamps, this type of charger would have been used to recharge one lamp at a time. The charger’s label reads “CAUTION: The Power required to operate this charger is designed on name plate. If in doubt consult your Electric Power Company. INDICATOR BULB May not light immediately if battery is dry or over-discharged.” This charger belonged to Grant Wheat’s personal collection that was donated to the museum in 1962.
