Mary Anderson, Inventor of Windshield Wipers

Mary Anderson

Did you know that windshield wipers were invented by a woman? Mary Anderson to be exact. We can’t imagine how dangerous and difficult it must have been to drive without wipers, otherwise hypothermia would set in. them. Here is a woman whose invention is Mary Anderson

• Can you imagine what it might have been like back in 1902 when automobiles were coming of age and highways weren’t even a thought. Dirt roads were the way to travel since the horse and buggy were the means of transportation until the invention of the motor car. The way to stay warm was to wear layers of clothing, and thank goodness for long dresses back in those days, otherwise must have been to drive without hypothermia would set in. them. Here is a woman whose invention is still in place today, and without it, seeing in inclement weather would granted every time we turn on our be difficult. Today we take it for windshield wipers. Back in the day until 1927, vehicles were what they called open cars, because they were completely open except for the windshield.

I begin my series of Women Inventors with the Windshield Wiper. Here is a short version of her invention. The photograph is a copy of the original draw- ing for the patent submitted.

• Born in Greene County, Alabama, Mary Anderson was a real estate developer by trade. However, on a business trip to New York in 1902 she noticed that during sleet storms trolley car operators drove with their heads poking out the side window Here is lady who took a bad because they could not see through situation and turned it into a life long the windshield. Upon returning to Alabama she invented a device consisting of a lever with a rubber blade attached that could be cranked from within the vehicle. Anderson was only granted a 17-year patent on the invention, meaning her rights to it expired before the mass production in the automotive industry began. As a result, she received little in the way of royalties from her invention. Even today, windshield wipers operate on the same basic design that Anderson created.

Hemi-Powered Classics Engines

Hemi-Powered Classics Engines

Hemi-Powered Classics If you remember the ’50s and ’60s, then the word “Hemi” can bring back some fond memories.

The Chrysler Hemi engines, known by the trademark Hemi, are a series of I6 and V8 engines built by Chrysler with hemispherical combustion chambers. Three different types of Hemi engines have been built by Chrysler for automobiles: the first (known as the Chrysler Firepower engine) from 1951 to 1958,[1] the second from 1964 to 1971, and the third beginning in 2003. Although Chrysler is most identified with the use of “Hemi” as a marketing term, many other auto manufacturers have incorporated similar designs.

Modern day Hemi

Chrysler, I feel, was way ahead of their time when they produced the Hemi. It produced a large amount of horsepower which was installed in your everyday family car.

What exactly is a Hemi engine, and why has it kept its flare all these years? The Hemi is a hemispherical combustion chamber, a type of combustion chamber in a reciprocating internal combustion engine with a domed cylinder head. The hemispherical shape provides a number of advantages over a reverse-flow cylinder head but comes up short in others, particularly in carbureted engines. An engine featuring this type of hemispherical chamber is known as a hemi engine.

A hemispherical head (“hemi-head”) gives an efficient combustion chamber with minimal heat loss to the head, and allows for two large valves. However, a hemi-head usually allows no more than two valves per cylinder due to the difficulty in arranging the valve gear for four valves at diverging angles, and these large valves are necessarily heavier than those in a multi-valve engine of similar valve area, as well as generally requiring more valve lift. The intake and exhaust valves lie on opposite sides of the chamber and necessitate a “cross-flow” head design. Since the combustion chamber is virtually a hemisphere, a flat-topped piston would yield too low a compression ratio unless a very long stroke is used, so to attain desired compression ratio the piston crown is domed to protrude into the head at top dead center, resulting in a combustion chamber in the shape of the thick peel of half an orange.

In 1951, you could go down to your local Dodge dealer and for the price of around $1,800 dollars you could purchase a beautifully built, American made car with a Hemi engine. It put out a whopping 180 horsepower.

The love for the Hemi is still alive and well with today’s classic automotive enthusiast. If you have a Hemi in your classic, you can bet car fans will flock to your vehicle, not only give it a look over, but I can bet you, conversation will be plentiful. You may even be asked to start up your vehicle just to hear that sweet sound of a hemi.

Family car powered by Hemi

There were some disadvantages to owning a Hemi engine. Significant challenges in the commercialization of engines utilizing hemispherical chambers revolved around the design of the valve actuation, and how to make it effective, efficient and reliable at an acceptable cost. This complexity was referenced early in Chrysler’s development of their 1950s hemi engine: the head was referred to in company advertising as the Double Rocker head. Domed pistons are commonly used to maintain a higher mechanical compression ratio, which tend to increase the flame propagation distance, being also detrimental to efficient combustion, unless the number of spark plugs per cylinder is increased.

Other drawbacks of the hemispherical chamber include increased production cost and high relative weight (25% heavier than a comparable wedge head according to Chrysler’s engineers). These have pushed the hemi head out of favor in the modern era.

So the next time you are visiting a classic car show, see if you can identify one with a classic Hemi engine. Happy Motoring.

Auto Shop, Is It A Dying Breed?

HAPPY MOTORING Teresa is a top-notch mechanic with more than 28 years of experience repairing everything from Porsche’s to school buses. Currently she teaches a basic auto-repair class for women.

Auto Shop, Is it a Dying Breed?

I recently discovered that the high school I graduated from is contemplating eliminating their Auto Shop class. I learned the possible fate from a high school friend on Facebook.This was quite concerning to me since I have been on a mission to help energize our younger generation to enroll in such classes not just to possibly one day become a mechanic, but to express that these types of classes teach more than just working with your hands.

On my weekly Radio Show, Teresa’s Garage, I have used my platform to interview female racers, mechanics, car enthusiasts, auto parts specialists, etc. It has a large following because of it and not just by women, but from men as well.

Healdsburg, Ca. High School Student

When I attended high school, it was forbidden for girls to enroll in Auto Shop since it was not appropriate for girls to be getting their hands dirty. That did not deter me one bit, I took it upon myself to be a self-taught mechanic and to tap into a mechanic’s mind that would be willing to reveal their secrets to me.

After learning the fate of the Auto Shop class, I decided to contact all the School Board members by email expressing the importance of keeping Auto Shop as part of their curriculum. I received an immediate response from the School Board’s Chair who explained why the board was considering removing the class and the challenges that they are facing.

The School Board had been hosting several meetings with public input to discuss the class and a possible solution on how to precede, either keeping it or eliminating it as an offered class.

This all surfaced due to the fact that students simply were just not enrolling, leaving them with a teacher ready and willing to teach, but without enrolled students. Plus the Auto Shop itself over the last several years had fallen into disarray.

But tight budgets and a pervasive emphasis on academics, especially college preparation, contributed to the decline of auto shop across the country what I discovered from my research. During years of overcrowding in several of the Unified School Districts, many shop rooms were converted to class rooms.

Yet many students still need vocational training, not to mention something to interest them enough to earn a high school diploma.

These are not your father’s or grandfather’s auto shop classes, where guys install glass-pack mufflers and cheater pipes on their cars.

It’s much more electronic, digital, computer-driven, in today’s world leaning more towards electric and self driving automobiles. But there is still the need for mechanical technicians especially with many of the mechanics in their retiring years leaving the pool. Who will fill their vacancies?

At high schools, efforts are underway to link surviving auto tech classes with physics, algebra and geometry – all topics important to understanding the modern internal combustion engine. This linkage with such core subjects could preserve auto shop, because it can win state approval as part of a college prep curriculum.

When you dig deep into what students are able to absorb from taking auto shop, it is not just learning to connect things or working with your hands, it goes beyond that. It allows the students to learn problem solving, which is an important part of everyday life and mathematical skills since most of being a mechanic has to do with sizes, metrics, measuring and building. Team building, learning to work together, communications, reading of repair manuals, diagrams, owner’s manuals and schematics-this is just the tip of the iceberg.

With young adults today burying their heads into their electronic devices, we are wasting precious minds and possible inventors by not allowing them to energize their minds and sparking their creative side.

If we look back into automotive history, you will find that Thomas Edison did not just invent electricity, but he also helped Henry Ford with the invention of Briquettes. If they had been preoccupied by electronic toys, where might we be today? So if you have young adults in High School, encourage them to enroll in Auto Shop, if not to be a mechanic, but to empower themselves.

With the multicast capabilities of satellite connectivity, all vehicles can receive updates simultaneously, exponentially trimming the time and cost of unicast terrestrial updates

Cars of today are actually a moving computer compared to cars of yester year. Computers are running everything from your tire sensors, to the engine performance and navigation systems insuring you arrive at your destination. Need help backing up; there are backup camera’s that assist you.

Not so long ago, computers were the size of your garage and now they are the size of your cell phone. Technological gurus have worked overtime to give all of us the convenience to communicate with family, friends or complete strangers anywhere in the world.

Autonomous cars are the up and coming future for transportation. Recently on my radio show “Teresa’s Garage”, I hosted local guests whom are knowledgeable in autonomous automobiles, since Nevada is the state leading the world in regulating, licensing and testing these types of vehicles, we had many questions.

Nevada is the first state to embrace this new technology, so much so that they have licensed the first autonomous vehicle to a Quadra paraplegic.

Autonomous plate

April Sandborn, from the Nevada DMV and Col. Dennis Osborne of the Nevada Highway Patrol, who have been spear heading this endeavor to insure these vehicles are safe, tested and properly regulated for our highways.

At first I was not one to embrace these unmanned vehicles for several reasons, but after interviewing these two amazing individuals, I have slightly changed my mind and they do have a place on our roadways.

The manufactures of these autonomous vehicles, still have a lot of testing to perform and bugs to work out, but with millions of dollars spent on this technology, it won’t be long before we begin to see more of these vehicles traveling along side of us.

This opens up an entire new world of independence to so many individuals who would have never received the opportunity, such as the Elderly, severe handicapped and even the young, if this technology had not been developed.

Cars That Shaped America

Cars That Shaped America

It is hard to imagine America without automobiles, since they are a huge part of everyday life. As we sit and watch old Westerns, we see that the source of transportation was once the horse and wagon. But transportation actually began with the horse, giving individuals the opportunity to travel a distance from their home.

So, what were the beginnings of the automobile? Depending on the type of vehicle you have a passion for, history shows that Henry Ford was the biggest influence in helping to shape America.

The first car was built in 1886 by Benz. In the initial stages, the car makers were going through several trial and error periods. With the discovery of oil, gasoline, and steel, a whole new world opened up to inventors.

In 1901 Henry Ford manufactured his first automobile. Henry failed at first, but was driven to keep going until he perfected his idea of driving an automobile. It didn’t take long for him to make a prototype that could withstand the rugged terrain. The best way to prove the vehicle’s soundness was to race the best drivers, which in turn, gave him great recognition.

Henry Ford

The one downfall of the early automobiles, was the weak ignition systems. This gave inventors even more ambition to perfect it.

In the early 1900’s, cars and horses did not mix. Until the invention of the automobile, people would not travel more than 50 miles from their homes.

Once Henry Ford introduced the Model T, the world changed forever. Untouched territory across America was being discovered. The Roaring Twenties gave the automobile a huge lift – the type of car you drove expressed your lifestyle. The automobile industry was going strong until the great depression of 1929, which seemed to halt America and the automobile manufacturers.

Dodge Brothers

Because of Henry Ford and his strong hold on the automotive industry, Chevrolet, Chrysler and Dodge were created. The Dodge Brothers actually worked for Henry Ford in the early years until they became disgusted with him taking all the credit for the vehicle designs, so they started Dodge. General Motors started not as an automotive company, but as a horse carriage manufacturer. Since they were being phased out by the Model T, the owner of GM decided it was time to design his own cars. Chrysler worked for GM until there was a falling out with the GM owner and he started his own company.

After the depression, cars were in full swing again until a brief stop in production during the First World War, when car manufacturers were instructed to stop making cars and turned to making military vehicles.

After the war ended, automobile production resumed and increased more than ever.  Henry Ford, because of his passion for the Model T, could not see beyond it and because of that, the other manufacturers were in full swing and gained ground, knocking Ford to the second largest automobile company.

So looking back to this one invention, the automobile, this single most important of all inventions, shaped America. Without them, we can only imagine what the world would look like today. But today we are falling behind foreign automobile manufacturers. We need to nurture inventors and innovators. We need to encourage our young people to create and look far beyond their cell phones. We need to spark their creative side and become  visionaries.

History tells us that when others questioned their inventions, people such as Benjamin Franklin, Einstein, Ford, and even Steve Jobs, all had visions for the future. Nothing good comes easy. If you believe in yourself, in your dreams, and your future, just imagine what might and can evolve from it.

Autonomous cars appear to be the future and many individuals are skeptical, but as you look to the past, so was their future. Happy Motoring.
