How the “The Real McCoy” Device Spurred U.S. Economic Growth

Working as a fireman on the Michigan Central Railroad, one of Elijah J. McCoy’s tasks was to lubricate locomotive engine parts using a handheld can. Having been certified as a mechanical engineer and finding it difficult to locate work in that field, McCoy became bored, so he used the time on the job to think: If a mechanical device existed that could allow the proper amount of oil to drip into the moving parts of the engine, a train would no longer have stop every few miles to be manually lubricated.

McCoy then became curious about the challenges of such a device and began to develop and test his ideas for automatic lubrication. After two years of experimenting in what was a makeshift machine shop, he designed a special lubricating cup that could be fitted into the steam cylinders of locomotives as well as other stationary machinery was developed (1872).

This device spread oil evenly over a train’s engine while it was still moving, allowing trains to run for long periods of time without stopping. McCoy’s invention saved both time and money, and for it, he received the patent for what was called

the Lubricator Cup on May 27,1873.

Within a short time, McCoy’s automatic lubricator, dubbed ^;1he real McCoy,” to distinguish it from the less effective imitations that soon flooded the market, had been installed on locomotives across the country.

“McCoy’s invention was a small thing,” author Aaron E. Klein wrote, “but it speeded up the railroads, and faster railroad deliveries spurred the economic growth of a nation.”

McCoy was born in 1844 in Colchester, Ontario, Canada, to parents George and Emillia McCoy who had escaped slavery from Kentucky. The family returned to the states in 1847 and settled in Michigan.

Young Elijah often took things apart and put them back together. Noticing the ease of their son’s mechanical abilities, George and Emillia saved enough money to send Elijah, then 16, to Edinburgh, Scotland, to begin an apprenticeship in mechanical engineering. Training of comparable quality at that time was not available to Black people in either the United States or Canada. After completing his education, McCoy returned to the states, joining his family near Ypsilanti, Michigan.

According to Klein, McCoy spent the “long and frustrating months” searching for work in engineering before finally resigning himself to the menial job of a railroad fireman because “in those days, engineering was regarded as white men’s work.”

Continuing to refine his devices and design new ones, McCoy received more than 60 patents over the course of his life; 50 dealt with lubricating systems.

Finances to manufacture the lubricators in large numbers was unavailable, so McCoy assigned his patent rights to his employers or sold them to investors. Lubricators with the McCoy name were therefore not manufactured until 1920, when the Elijah McCoy Manufacturing Company was formed.

McCoy died in Detroit on October 10,1929. He was 85.

Women & Wealth: Tips for Navigating Your Lifelong Financial Journey

Sponsored by J.P. Morgan Wealth Management

We are in the midst of a seismic shift in wealth. This phenomenon, often referred to as the “Great Wealth Transfer,” describes the unprecedented movement of assets from the Baby Boomer generation to their heirs – an estimated $105 trillion by 2048. And women are poised to inherit most of this.

J.P. Morgan Wealth Management’s 2025 Investor Study found that women are not only set to receive significant wealth – they’re actively working to build it on their own. Ninety-three percent of women surveyed who are expecting an inheritance aren’t relying on it to reach their goals.

Here are a few tips for women to consider in their wealth-building journey:

Create a financial roadmap

A detailed, well thought out plan is important. J.P. Morgan’s study found that 90% of those surveyed with a plan feel confident about reaching their financial goals, compared to 49% without one.

Your plan should reflect your unique goals, priorities and circumstances. Consider your investment horizon and risk tolerance, and remember to revisit your plan regularly as life evolves.

Are you saving up for goals like buying a house, sending your kids off to college or retiring early? Where do you want to be in the next five, ten or twenty years? Everyone’s financial situation is unique, so it’s important to think about these questions and build a plan that is unique to your life.

Women tend to live longer than men on average. Many take career breaks or care for family members, which can influence long-term planning. It’s important to adjust your strategy with these factors in mind.

Where to start with investing

Don’t let misconceptions hold you back. Starting to invest doesn’t require a large sum, and beginning early can be beneficial. The earlier you start, the more time your money has to potentially grow over the years. Understand your overall financial situation, set clear goals and develop a long-term plan.

It’s important to also make sure you’re covered for unexpected expenses that come up before you start to invest. Build up a cash emergency fund, typically enough to cover three to six months of expenses, and pay down any high-interest debt.

Taking charge of your finances

The good news is that women are taking charge of their finances. J.P. Morgan’s research found that 75% of women respondents make financial decisions with their partner or take the lead themselves. For those who have a spouse or partner, it’s important for each person in the relationship to play an active role in the process.

Building wealth can be empowering for many women. The same survey found that 73% of women respondents said money gives them “security,” while 64% of Gen Z and Millennial women associated it with “freedom.”

The power of having a team

Some people find it helpful to work with a financial advisor, so you don’t have to tackle things alone. An advisor can help you craft a plan tailored to your needs and keep you on track throughout your lifelong financial journey. If you expect to receive an inheritance, you should also consult with estate planning and tax professionals.

No matter where you are on your wealth-building path, education is key. It’s so important to be an informed investor, and there are plenty of resources out there to help. You can find a library of free educational resources at chase.com/theknow.

As the landscape of wealth continues to evolve, women have a unique opportunity to shape their financial futures and those of generations to come. By staying informed and planning ahead, women have the tools to help them confidently navigate the Great Wealth Transfer and set themselves up for financial freedom.
