Waterwheel and Gears Turning
Again
Yes
-- you can now watch the corn being ground for you to purchase as
corn meal at the NEW "Old Grist Mills at Union Mills. Compromises have been
made in the reconstruction of the Mill because of the extensive cost of
material and labor but the basic conception of the "Oliver Evans" mill was
brought into being by millwright, Derek Ogden, originally an electrical
engineer at a General Electric plant in Birmingham, England. Mr. Ogden' s
part-time job on a windmill at Compton Wynyates was well publicized, other
offers came and Mr. Ogden was able to make a full-time career as a
millwright. Windmills and water powered mills have taken him to France,
Tasmania, South Africa, India as well as Britain and the U.S. He makes his
home in Surry County, Virginia where much of the wood work was completed
before moving the mill parts to the finale location for installation.
According
to Mr. Robert (Max) Bair, county community development director, Carroll
County has spent about $260,000 - with 3/4 of the amount covered by state
grants, reworking the mill to the present day useful state. This is far from
the original cost. The following is copy taken from research by Sandy Ross,
a former curator;
On
January 25, 1797 the Shriver Brothers had contracted with John Mong, a
Frederick County millwright for $420 to begin supervising and building a
set of mills... .
...John
Mong agrees to build a Sett of Mills.. . with a Mill for Manufacturing
grain into flour. To comprehend Two Water Wheels of double geer for
Three Pair Grinding and one Pair Shelling Stones. Compleat one Merchent
and one Midling Bolt-With Chest Mixers. Packing Rooms, Rolling Screen
and Appendages. Hopper Boy and Packing Machine and Compleat one Country
Bolt and Chest and one Buckwheat or Corn Bolt and Chest. Two Setts
Hoisting Geers and With everything else Needful and Necessary to the
above described Work ... .
The day
after contracting with John Mong for " a sett of mills" the Shriver Brothers
made an agreement with Henry Kohlstock, carpenter, on January 26, 1797:
"Witnesseth
that for and in consideration of one hundred pounds to be paid by the
said Andrew and David Shriver to the said Henry Kohlstock, he, the said
Kohlstock, agrees to finish two small houses, fourteen by seventeen feet
each, to be connected by a porch and passage about ten feet wide,- -
.that is to say, he is to do all the joiner work so as to complete said
houses, passage, porch and stairways, agreeably to a plan thereof now
produced; also to do all the carpenter work of a mill house forty by
fifty feet, and to complete the whole thereof in a sufficient and neat,
workmanlike manner, as expeditiously as possible; and further, finally
to complete the whole, he is to paint the work, both dwelling and mill
house, in a proper and sufficient manner; they, Andrew and David
Shriver, to find all the materials, paint, oil, etc.
"R.
McIlhenny , John Mong, Witnesses" Andrew and David Shriver on March 13th
of 1797 contracted a "Memorandum of Agreement" with Jacob Keefer and
John Eckart to "Mould and Burn a Kiln of Brick" for the mill and to
provide 100,000 brick or more as would be directed. The Shriver Brothers
agreed to pay Keefer and Eckart "at the rate of a French Crown for Every
Thousand of Merchentable good sufficient Brick" and to provide their
"Board and Lodge".
Cost does
not show in the papers I have on the Mill House but we can be sure it was
reasonable. The new Waterwheel has been built of
white oak and is a breastshot arrangement.
The
dimensions of the wheel are 15' 6" in diameter by 6' wide - supported by
eight arms morticed through a sixteen sided white oak shaft which measures
26" across the flats. There are forty-eight
buckets which have been ventilated and arranged to
provide as much power and speed as is possible from a relatively inefficient
design operating on a low head of water. The total weight of the waterwheel
is approximately 16,000 pounds of which the shaft alone accounts for 9,000
pounds.
The
gearing of the mill is contained in a very traditional Evans Husk Frame
built entirely of white oak and is a heavy construction to house three pairs
of millstones driven by counter shafts. The frame is 31' in length by 9 '
wide by 8' 4 " high and weighs over 20,000 pounds. It houses gearing with
one set of millstones at this time, but provision is made to add two more
sets of stones, two driven from a countershaft and the third from a short
countershaft. Each countershaft has a lantern gear wheel driven by the
master cog wheel and in turn the millstones are further geared by little cog
wheels and a small lantern gear wheel. All gears are built of white oak and
have cogs or rounds made from ironwood.
From
existing examples and a lot of research it was possible to produce a design
for Union Mills which has few compromises. We must not forget these grist
mills were built only to earn a living for the owner and were never intended
to be museums nor with any thought to historic preservation. They were
simply hard working agricultural machines which were repaired and sometimes
improved as they wore out.
We think
you will enjoy your visit to the Grist Mill.
