Grandfather Francis had an enterprising spirit. While to his father Josef, who opened a mill in Trojanovice in 1861, customers came with cloth bags of buckwheat, to Francis customers came with carriages pulled by horses or cows. Josef's father's mill equipment was „žerno“, two millstones with which he manually twisted and separated the husk from the buckwheat grain. Francis, who took over business in 1911, was full of ideas on how to improve or modernize the mill. He never spoke very much. Some days you could not see him all day long, you could just hear cutting, planing or creaking from somewhere in the barn. Then the door opened suddenly and in it stood all white from the sawdust Grandfather Francis next to the brand new cleaning table. As a trained wheelwrightat Sustal's Koprivnice carriage, he was able to deal with everything. He made a wooden floor in the mill, built a blower and a simple sorting machine, nicknamed trier.
The mill was not moved by hand but with the help of a cast iron drive machine which he bought from the then manufacturer Strojirny Blansko. There was a cattle or a horse in it. The animals walked slowly around the ground, the wheels of the gears spinning and the sacks of flour were piling up in the mill for the whole village and the surrounding area.
The greatest change in the life of grandfather Francis was caused by the introduction of electric current. One day two horses stumbled into courtyard pulling the carriage with a cargo covered with tarpaulin. Their hair shone with sweat and they snorted with exertion. The sound of the wheels on the stone pavement prompted curiosity among the people in the mill and they began to sneak into the yard as if expecting a great event. Grandfather Francis took his time. Slowly walking around the horses he was checking their horseshoes and patting them on the back. He enjoyed the moment of tension. When his wife Mary could not hold it any longer she asked him cautiously: "What did you bring Francis?" And with a smile he pulled out the cover and said: "Electromotor."
