Inventor of Automatic Gear Shift & Turn Signals - Revolutionized Driving
1878 – 1963
🇺🇸 United StatesRichard B. Spikes was born in 1878 in Dallas, Texas, during the Reconstruction era when African Americans faced systemic discrimination despite the formal end of slavery. Growing up in Texas, Spikes developed a fascination with mechanics and how things worked. In an era when formal education was often denied to Black Americans, Spikes taught himself mechanical engineering through observation, experimentation, and natural talent.
Early in his life, Spikes moved to California, where he worked in a variety of mechanical fields. He understood that automobiles represented the future of transportation, and he focused his inventive talents on solving problems in automotive design and safety. The early 20th century was the dawn of the automobile age—cars were becoming more common, but they remained difficult and dangerous to operate.
In 1932, Richard Spikes received a patent for his automatic gear shift mechanism. Before this innovation, drivers had to manually shift gears using a clutch pedal and gear lever—a complex process requiring significant skill, coordination, and strength. Manual shifting was particularly difficult in stop-and-go city traffic, and many people found it too challenging to master, limiting who could drive.
Spikes' automatic gear shift eliminated the need for manual gear changes. His design allowed the transmission to automatically select the appropriate gear based on the vehicle's speed and load. While modern automatic transmissions are far more sophisticated, using hydraulics, planetary gears, and electronic controls, Spikes' 1932 patent established the fundamental concept: a transmission that shifts itself without driver input.
The impact was revolutionary. Automatic transmissions made driving accessible to people who lacked the strength or coordination for manual shifting, including many women, elderly drivers, and people with disabilities. They reduced driver fatigue, made city driving less stressful, and allowed drivers to focus more attention on traffic and road conditions rather than gear selection. Today, the vast majority of cars sold in America have automatic transmissions, all descendants of concepts pioneered by inventors like Richard Spikes.
Spikes also invented automatic directional signals for automobiles—what we now call turn signals or blinkers. Before this invention, drivers indicated turns using hand signals extended out the window—ineffective at night, in rain, or when other drivers weren't paying attention. This led to frequent collisions at intersections and lane changes.
Spikes' turn signal system used lights mounted on the vehicle's exterior that flashed to indicate the driver's intention to turn or change lanes. His design included automatic cancellation after completing the turn. This invention dramatically improved road safety by providing clear, visible signals that worked in all weather conditions and lighting.
Modern turn signals are standard equipment on every vehicle worldwide, mandated by law in virtually every country. They prevent countless accidents daily by allowing drivers to communicate their intentions to others on the road. Every time you flip your turn signal lever, you're using technology pioneered by Richard Spikes nearly a century ago.
What makes Richard Spikes' story particularly inspiring is that he continued inventing even after losing his sight. Later in life, Spikes went blind, yet he refused to let this disability end his creative work. He developed a drafting machine for blind designers that allowed him to continue creating technical drawings and developing new inventions despite his lack of vision.
This drafting tool used raised lines and tactile markers, enabling blind inventors and engineers to create precise technical drawings by feel. It demonstrated Spikes' determination and his understanding that disability does not mean inability—it simply means finding different methods to achieve the same goals.
Spikes' perseverance through blindness exemplifies the resilience that characterized many African American inventors of his era. Facing both racial discrimination and physical disability, he nevertheless continued contributing technological innovations that improved life for millions of people.
Beyond the automatic transmission and turn signals, Spikes held numerous other patents. He invented an improved beer keg tap that prevented waste and contamination. He created a combination milk bottle opener and cover that made milk bottles more sanitary and convenient. He developed a safety brake system for vehicles that provided better stopping power and reduced accidents.
His inventions spanned multiple industries—automotive, food service, industrial equipment—demonstrating his broad mechanical abilities and his knack for identifying everyday problems that needed solutions. Each patent represented months or years of work: conceptualizing the solution, building prototypes, testing, refining the design, and navigating the patent application process.
Richard Spikes' contributions to automotive engineering have had lasting impact. The automatic transmission freed millions of people from the complexity of manual shifting, making driving accessible and comfortable. Turn signals became standard safety equipment, preventing countless accidents by improving driver communication on roads.
For African Americans, Spikes represents the rich tradition of Black inventors whose contributions to technology have often been overlooked or forgotten. His story challenges the false narrative that technological innovation was the exclusive domain of white inventors. In reality, African American inventors like Spikes were creating transformative technologies despite facing systematic barriers and discrimination.
Today, when you drive a car with an automatic transmission, signal your turns with the flick of a lever, or benefit from improved braking systems, you're experiencing the legacy of Richard B. Spikes—a self-taught African American inventor from Texas who saw possibilities others missed and who continued creating even after losing his sight. His life embodied the determination to overcome any obstacle in pursuit of innovation that improves life for everyone.
Richard Spikes' automatic transmission made driving accessible to millions, while his turn signals became mandatory safety equipment preventing countless accidents worldwide. Despite going blind, he continued innovating, proving disability cannot stop determination.
Richard Spikes' inventions fundamentally changed how people drive. Before automatic transmissions, operating a car required significant skill and physical capability—drivers needed strength to depress the clutch, coordination to shift gears smoothly, and constant attention to engine speed and vehicle load. Manual transmissions excluded many people from driving and made city traffic exhausting even for experienced drivers.
Spikes' automatic gear shift changed this, making driving accessible to millions who lacked the strength or coordination for manual shifting. Women, who in the 1930s-1950s often found manual transmissions physically challenging, embraced automatic cars. Elderly drivers could continue driving safely longer. People with certain disabilities gained independence through accessible transportation. Today, automatic transmissions dominate the American market, with over 96% of new cars sold with automatics—a direct result of innovations pioneered by Spikes and other early automatic transmission inventors.
His turn signals addressed a critical safety problem. Before directional indicators, intersection collisions and lane-change accidents were far more common. Hand signals worked poorly in rain, darkness, or when other drivers weren't looking. Spikes' lighted turn signal system provided clear, visible communication of driver intentions regardless of conditions. Modern traffic law mandates turn signals on all vehicles, and their use prevents thousands of accidents daily worldwide.
What makes Spikes' achievements particularly remarkable is that he accomplished them despite facing enormous barriers. As an African American in the early-to-mid 20th century, he faced systematic discrimination in education, employment, and access to capital. The patent system often denied Black inventors their rightful credit or compensation. Yet Spikes persevered, teaching himself mechanical engineering and successfully patenting numerous inventions.
His continued innovation after going blind exemplifies extraordinary determination. Rather than accepting disability as an end to his creative work, Spikes invented tools that allowed blind people like himself to continue designing and creating. This adaptive innovation demonstrates how challenges can inspire solutions that help entire communities of people facing similar obstacles.
For African Americans and the disability community, Richard Spikes represents a powerful example of how determination and creativity can overcome any barrier. His story challenges assumptions about who can be an inventor and under what circumstances innovation can occur. Every automatic transmission, every turn signal, every adaptive technology for people with disabilities carries forward his legacy of seeing possibilities where others saw only limitations.
