Preserving our global heritage for signaling time, prior to modern electronic methods, were time balls, time guns and time flaps that synchronized with the local astronomical observatory. First dropped in 1829 at Portsmouth, England, they remain today an ornamental and educational attraction in many locations around the world.

Why Are Headstones Arranged In Circles

By Leland L. Hite, 200 KB, PDF

The traditional configuration of facing the headstone along an east west axis and positioning the body with the head pointing west, thereby allowing the feet to see the rising sun, was not followed with this pattern; instead, the wheel pattern was used, but why?

By: Leland L. Hite, 3.3 MB, PDF

Dodges Institute of Telegraphy (DIT) began in December 1873 and became the largest school of its kind in the Western Hemisphere. The institute evolved into wireless telegraphy and courses in radio technology were added to the curriculum.

 In 1944, DIT was renamed Valparaiso Technical Institute (Valpo Tech or VTI). Rated among the top 10 such educational organizations in the world, Valpo Tech became the oldest electronic institute in the country. The school celebrated its final graduation on May 25, 1990, and closed its doors after the January 1991 graduation.

Lightning Safety Guidelines and Event Safety Plan 
By: Leland L. Hite, 80 KB, PDF
If you can see lightning or hear thunder, you are in danger!

While your chance of being struck by lightning in your lifetime is estimated at 1 in 5,000, it is much better than winning the lottery. Participating in high-risk outdoor activities when lightning approaches can increase your odds of a lightning experience. You can significantly reduce your risk by practicing these guidelines.

These guidelines are from classroom handouts provided during continuing education credit classes for lighting safety, by Electrical Engineer, Leland L. Hite.

YES: it's okay to ask your outdoor event planners about their event safety plan for lightning.

ASK: The Coach, The Referee, The Umpire, The Administrators, The Parents, The Event Planner, or the Sponsor.

Obed Hussey and His Ohio Test of the First Successful Reaper

By Robert T. Rhode and Leland Hite, 40 MB, PDF

Our work breaks new ground on an event that was of tremendous importance to the world: the testing of the first successful reaping machine, which revolutionized agriculture globally in the nineteenth century and started farming down the path toward industrialization. That test, with its far-reaching consequences, took place near Mt. Healthy, Ohio, in 1835. Even though books and articles from the 1800s and early 1900s noted the achievement, it has been largely overlooked in our time, and it has never been fully researched and described. Bob and I made it our mission to investigate the matter thoroughly. Over the past year, we discovered many surprising facts that had been forgotten or that had never been brought to light.

The First Cable Suspension Bridge Built in Ohio
By Robert T. Rhode and Leland Hite, 5.6 MB, PDF

On the 12th of December (2014), Leland Hite and Robert T. Rhode, acting on behalf of the Mt. Healthy Historical Society, recovered the last remaining component of the first cable suspension bridge built in Ohio. The 167-year-old iron tripod was one of four that had supported the cables of the 42′ bridge crossing the West Branch of Mill Creek near Mt. Healthy. Built in 1847, the footbridge on the Lane family farm was the brainchild of William Lane, brother of Clark Lane, the noted industrialist whose company of Owens, Lane and Dyer manufactured steam engines and sawmills in Hamilton, Ohio. The ingenious bridge was one of the first suspension bridges in the United States.

From The Ship Shape Sharp Shop, by Ersal Kindle
Berea College Symposiums, WOOD TURNING and JOINERY
May and June, 1985

"A Sharp Tool Is A Safe Tool, has been said many times and I say it again. Not only that but there is joy in using a sharp tool. There is a lot of satisfaction in making smooth clean cuts in a piece of wood, but---this is nearly impossible if the cutting edge is not sharp. So, let's see how we can get and hold a sharp edge. I'll show you one way − the way I do it."
