John Bouchard becomes mechanical superintendent of Armour and Co., the nation's largest meatpacking factory. He devises three inventions which recieve US Patents – a hog-scraper, ammonia refrigeration machine and a switch for overhead tracks/rails.

Bouchard moves to Nashville, partnering with his sons, John E. and James, to open a shop on Harrison Street. They advertise as "engineers, founders and machinists," with specialties in refrigeration and elevator work.

The Bouchard crew has built a reputation for craftsmanship, versatility and mechanical expertise. Projects are completed for Vanderbilt Hospital, Hermitage Hotel, Standard Candy, Weyman-Bruton (now US Smokeless Tobacco) and the city pump station at Omohundro Dr.

Though the nation struggles through a depression, JBS invests in the future, opening a new foundry, which employs 50 men. The newspaper touts the plant as “one of the most complete of its kind…anywhere in the South.”

In 1925, the fire-sprinkler department is launched. It will go on to grow dramatically during the WWII years, installing fire-protection systems for customers such as the AVCO plant.

Surviving the Great Depression, JBS continues to expand its services as John E. Bouchard, Jr. becomes the third generation president at age 29. Contributions to the WWII effort will include extensive projects at Ft. Campbell, Sewart Air Force Base and the Army Air Classification Center.

A new, 20,000 sq. ft. foundry is built to quadruple production of iron construction castings. The new plant will allow JBS to become the most utilized supplier of manhole covers, curb inlets and other municipal castings in the mid-South.

The year John E. Bouchard III becomes president, the mechanical department installs the HVAC system for TN Tufting Company’s new warehouse. The Bouchard crew sets 23 a/c units on the roof in just two hours, using a helicopter.

Brothers, Bill & Ira Gadd retire after 106 combined years of service in the machine shop. They represent hundreds of others who have invested their working lifetime and built their families through the generations at JBS.

As the company celebrates its 75th anniversary, its electrical department continues to expand services - installing power service, wiring & distribution, lighting and control circuits for commercial and industrial installations.

Building on its foundation in refrigeration compressor work throughout the early 1900s, JBS enters the plant compressed air market, providing complete compressed air systems and round-the-clock service. Knoxville compressor and pump sales & service office is opened.

Gardner Denver selects JBS as its exclusive air compressor distributor in the entire Kentucky and Southern Indiana territories. JBS opens offices in Evansville, IN and Elizabethtown, KY, hiring full local staffs of highly-experienced technicians and product experts.

After 120 years in business, John Bouchard & Sons Co. becomes certified as a Woman Business Enterprise (WBE).

Today, JBS continues its longstanding tradition of building and sustaining infrastructure with excellence.
