HISTORY FACT

  ROCK CRUSHER AND STORAGE BINS Men smashed the refuse stone that accumulated throughout the quarry into about 20-inch chunks using 18-pound hammers.  Small railroad dump cars carried the scrap rock from blasts along with spalls (chips) from the stone and paving cutters to the stone crusher.  The stone was dumped into the  oval-shaped, steel-lined crusher that was mainly underground.  There a huge revolving  egg-shaped, air powered steel crusher  about six feet in diameter and 10 feet high  smashed the rock against the steel walls.  As the rock broke into smaller pieces, it fell into a deep pit under the crusher where a conveyor belt elevated the stone to the top of the storage building.  The conveyor dumped the rock according to size.  The rock fell through the screens into six huge bins (10x20x10 feet each).  The classified rock was stored in the bins.  Standard size of the crushed was two and one half  inches; it weighed 2200 pounds per cubic yard.  The rubble, used for small founda

 We are doing are very first outdoor movie on the lawn of the historic sandstone high school also know as the rock! Come check it out!

A FUN FACT ABOUT THE DERRICKS

  DERRICKS The early derricks in the quarry were made of wood and run by horse and steam power.  American Hoist and Derrick Co. of St Paul built and installed many of the approximately 100-foot derricks.  A few of the later derricks installed were steel.  Each mast had about eight guy wires running in all directions secured in the rock anchor and stabilized it.  Some guy wires were anchored on the other side of the river.  The hinged beams attached to the masts that lifted and guided the mill blocks were called booms.

  WHISTLE The whistle was in one of the stack pipes on the saw mill.  It blew in the morning to mark the beginning of the work day.  At noon and 1p.m. for the beginning and end of lunch break, and late afternoon to signal the end of day.  When the last whistle blew, the workers dropped their tools and hurried out of the quarry. BLACKSMITH SHOP Usually ten blacksmiths worked in the blacksmith shop.  John Gjertson was the head blacksmith for many years supervising the blacksmiths as they sharpened tools, made picks hammers, chain link and wedges for splitting rocks.  Alfred Orstad was one of many blacksmiths who spent long hours sharpening the six-foot and 20-foot drills that dulled quickly boring through the hard sandstone.  Al VanDerWerf was one of many young men whose first job was to carry the 20-foot drills and other tools from the blacksmith shop to the top of the hill.  He protected his shoulder from the cutting edge of the heavy drills with a gunny sack

SANDSTONE QUARRY FUN FACTS

SAW MILL Flatbed railroad cars carried large mill blocks of sandstone from all over the quarry to the saw mill where derricks lifted the blocks onto smaller railroad cars that ran right into the mill.  Saws suspnded from the ceiling cut the sandstone right on the flatbed cars.  Stone for sidewalk slabs, paving and other non-building uses were cut by steel saws.  Diamond saws cut the finer stone destined to be used for building blocks and trim.  The saws were not the standard type with jagged edges.  Each saw was a long straight band of steel about 12 feet long, six inches high and three-fourth of an inch wide.  George Brickman worked in the saw mill for many years.  He and the saw mill crew operated the saws, run by air compressors, that cut by wearing the sandstone away as they moved back and forth across the stone.  Water constantly ran on the saw and stone to keep the saws cool and wash away the sand.  Six steel saws, about five feet wide, could each make up ten cuts in a mill block

FUN KNOWLAGE OF THE QUARRY

HOIST HOUSE The first building on the right side of the bridge was one of 25 hoist houses in the quarry housing machinery that provided power to the derricks.  The huge sandstone mill blocks were lifted and moved with cable that ran from the boom on the derrick to the hoist.  The cable wound around a huge drum.  In the late 1890s one horse harnessed to a drum walked round and round providing power to the lift and move the mill blocks.  Hydropower from the dam tat ran an air compressor soon replaced the horse.  Later electric motors and gas powered engines ran the hoist operated by Axel Larson, Axel Anderson, Victor Gjertson, Elmer Nelson and other hoist operators who moved levers to turn the drum that lifted, lowered or guided the boom carrying the sandstone mill blocks.  DAM This dam was called the old dam after the new dam was built down river in 1905.  The dam provided power for the huge saw mills that cut the stone and drills that bored through the sandstone.
