What Are Sheaves?

It's a numbers game with a storied background that also offers comfort to parishioners. The "sheaves" definition can take on many connotations depending on how it is used.

What Are Sheaves?

Sheaves of grain are a farmer's delight. When bundled up in thick, tall groupings, a sheaf is a physical collection of tall grains that have been bound and prepared for further processing. A sheave is also a pulley that can carry a lot of weight over a large area when paired with multiple pulley systems. A single sheave can pull a heavy load up and over a great height.

While that sounds simple enough, the term "sheaves" has been around for hundreds of years to describe and inspire more than a bundle of a worthy crop.

How to Define "Sheaf"

There are other ways to define "sheaf" aside from how it holds up in the field. It may have begun as a word for farmers to describe ways of wrapping up important crops, but it has spread to also include the following definitions:

  • A number of single documents held together is a sheaf of papers.
  • Arrows bound together in a quiver are called a sheaf of arrows.
  • Sheaves are a round pulley system for hoisting heavy objects.

Sheaves in Machines

The word "sheave" is also used in mechanics. The definition of a sheave when used in the context of working on engines or lifting heavy objects is the same as a hoist.

It is used as a pulley or hoist with a grooved wheel that holds a belt, thick wire or rope. They can be used to redirect a wire, rope or cable in order to lift loads and parlay power to other areas.

An adjustable-speed sheave is specifically designed to tolerate changes to the driven shaft speed where the drive motor speed is static.

Sheaves for DIY Projects

The nonmotorized sheave does a lot of work for a simply constructed pulley system. When used in home improvement projects, a block-and-tackle system can move impossibly heavy objects to fit snugly and securely in other areas of the property. The right-sized sheave and pulley system can make a significant difference in moving large objects and lifting substantial items.

Sheaves work well for hoisting heavy bundles, for placing bundles of fencing, concrete blocks or pavers for a backyard patio project or for moving mature trees for a landscaping job.

Sheaves in Farming

Simply put, a sheaf is a bundle of wheat, rye or other cereal plant that has long stalks. These stalks are put into orderly bundles and wrapped around the middle to create sturdy parcels of grain for drying out and shipping.

Traditionally, teams of workers with scythes would hand reap a field of grain. They worked clockwise from the outside edge to the middle. Sheavers used a long stalk to tie the loose stems into an upright bundle that is called a "shock."

A shock is made up of three to eight sheaves. They are placed in a pyramid-like pile with the cut stems forming a wide bottom. The grain heads at the top are well ventilated with this type of self-supporting A-frame. The way that the sheaves are placed into a triangular shock makes them easy to pick up by hand or by a machine.

Sheaves and Scripture

Sheaves of grain are revered in the Bible and in ancient cultures. The bundles were appreciated for the hard work that went into growing, harvesting and drying out these beneficial crops.

It was the focus of a popular gospel song in the late 1800s. The song, mostly used by Protestant christians, was inspired by Psalm 126:6. Lyricist Knowles Shaw wrote the song based on the passage: "He that goeth forth and weepeth, bearing precious seed, shall doubtless come again with rejoicing, bringing his sheaves with him."

Surprisingly, Shaw's moving lyrics went without music for years. George Minor put music to Shaw's lyrics in 1880_._
