Landmark 280 – Do you or someone you know wear glasses? If so, it’s very likely that you’ve benefited from the Lensometer. The Lensometer is used primarily by optometrists and opticians to identify and to verify eyeglass prescriptions.

:
• Before the invention of the Lensometer, optometrists determined eyeglass power through trial and error
• The first Lensometer successfully marketed on a commercial scale was the Wellsworth Lensometer in 1921
• Modern commercial lensometers are no more accurate than the Wellsworth Lensometer introduced over 100 years ago

🎉 🎈 🎂 Happy birthday to the Disneyland Resort Monorail System! It opened on this day in 1959 and became an in 1986.

Walt Disney considered the Disneyland Monorail System a futuristic form of public transportation. While monorails never became a widespread way to get around, Disney was on to something—the Disneyland system was the first monorail operating daily in the Western Hemisphere and the first monorail system in the United States!

The trains run on pneumatic tires that support the weight of the vehicles, with additional tires along the track to guide and stabilize the train. Initially running eight-tenths of a mile, the track is now 2.5 miles long, and trains reach speeds of 35 MPH. It's estimated that a billion people have ridden the monorail since its opening.

Let's travel back in time to 1880 for a bit of ASME history that you may not know about...⁣

What you're looking at is the Edwin A. Stevens Building at Stevens Institute of Technology in Hoboken, New Jersey, where one of the first official ASME meetings was held!⁣

Stevens Institute of Technology's first professor of mechanical engineering, Robert Thurston, was a trailblazer in the engineering industry. Inspired by his mission, Dr. Henry Morton, Stevens' first president, invited Thurston and other early leaders to host an "organizational" ASME meeting at the school. ⁣

During this meeting, Thurston was announced as our first official president, paving the way for our modern-day ASME leaders!⁣

December 6, 1877, was a historic day for No. 68!

On this day many years ago, inventor Thomas Edison put tinfoil around the cylinder of his phonograph, turned the handle of the shaft, and sang a verse of "Mary Had a Little Lamb" into one of the diaphragms. To everyone's surprise, the device played back the recording clearly.

Although Edison set this invention to the side in 1878 to work on the incandescent light bulb, he continued to improve the device years later alongside inventors such as Alexander Graham Bell and Charles Tainter.

We're sure that Edison would be amazed that we now have compact smartphones with the ability to record and replay sounds!

This is where the modern petroleum industry began! The Drake Well in Pennsylvania was the first commercial oil well in the United States. It was built in 1859 by Edwin Drake, a former railroad conductor, by drilling through the soil with a 6-horsepower steam engine. Drake inserted a 32-foot-long cast iron pipe into the drilled hole and drilled inside it, protecting the hole from collapse. Eventually, the well reached its maximum depth of 69.5 feet.

Unfortunately, Drake’s well sparked an oil boom in Pennsylvania, and he never turned a profit. The well ran dry in 1861. Over the ensuing years, Drake’s unsuccessful investments in oil stocks left him impoverished. In honor of his contributions to Pennsylvania’s economic success, the state awarded him an annual income of $1,500.

Drake’s well became an in 1979, and today you can visit a replica of Drake's setup at the Drake Well Museum and Park in Titusville, Pennsylvania.

🚀 Today in 1967, the Saturn V rocket launched for the first time. Designed as part of NASA - National Aeronautics and Space Administration Apollo program, this rocket was designed to be larger and more powerful than any rocket previously attempted. ⁣

Developed at a cost of more than $7 billion, the Saturn V rocket was built based on F-1 and J-2 engines, and the final version stood 363 feet tall and weighed 6.1 million pounds when fully loaded. More than 50 years after its first launch on November 9., 1967, the Saturn V is still the tallest, heaviest, and most powerful rocket ever operated.

The Saturn V rocket had three stages: ⁣

1️⃣ The first stage weighed 300,000 pounds, measured 33 feet in diameter and 138 feet long, and powered the launch to an altitude of about 200,000 feet. ⁣

2️⃣ The second stage generated a total thrust of one million pounds. It weighed 95,000 pounds empty—and more than a million pounds when loaded with the 260,000 gallons of liquid hydrogen and 83,000 gallons of liquid oxygen it burned during flight. ⁣

3️⃣ The third stage had two burns: the first, lasting 2.75 minutes, put the vehicle into a circular orbit, and the second, with a duration of 5.2 minutes, positioned it for lunar intercept. ⁣

Although the Saturn V was retired in 1973 after launching Skylab, it is still the only launch vehicle ever to take humans beyond a low earth orbit. ⁣

In July 1980, ASME declared the rockets an . Today, Saturn V rockets are on display at NASA facilities in Alabama, Texas, Florida, and Mississippi, and at the National Air and Space Museum () in Washington, DC. ⁣

Ever wondered how pineapples were sliced and canned? Since 1913, the process has been automated! The earliest machines took one location from 15 pineapples a minute when cut by hand to more than 50 when cut by machine. While machines have grown more sophisticated in the century since their invention, the newest ones are still based on the principles of the first pineapple slicing machine, which was patented by Henry Ginaca in 1912. Ginaca's creation was named an in 1993.

Good news -- The Big Surf Waterpark, an , will likely reopen for the 2022 season! Here's a bit of history to know before you buy your tickets:

The waterpark was inspired by the surfers that construction engineer Phil Dexter saw on his daily commute home from work. Dexter later created his own wave pool in 1966 right in his own backyard, which paved the way for the Big Surf AZ.

The waterpark houses the U.S.'s first wave pool with a singular traveling wave, to open in 1969 in Tempe, Arizona. The waterpark later became an in 2013 and is still open today.

The waterpark uses 15 gates that empty water into a 2.5 acre lagoon with contours that replicate a natural beach. Its waves are produced by pumping water to a pre-selected height and are released through underwater gates.

The water released breaks over a baffle (similar to a natural reef), forming one wave per cycle. Water is then recirculated to the lagoon through pumps.

While Big Surf still operates as a waterpark today, it's also served as a concert venue to host musical acts like Pink Floyd, Elton John, the Red Hot Chili Peppers, the Beach Boys, Chicago, Sting, Rod Stewart, and more!

Do you use a ballpoint pen to take notes at work, at university, or even to write out your grocery list? You can thank László Bíró, who invented these handy devices back in 1938!⁣

Here's a quick history of Bíró's invention:⁣
As a journalist, Bíró noticed that the ink used in newspaper printing dried quickly and smudge-free, but was too viscous to flow through the tips of traditional fountain pens. The solution? A new type of pen featuring a tip with a ball that turns into a socket, picks up ink from a cartridge, and then rolls to deposit it onto paper.

In 1945, manufacturer Marcel B**h bought the patent from Bíró for the pen, which soon became the main product of his BIC company, which you're probably familiar with! Many years later in 2005, a collection of some of Bíró's earliest models was highlighted as an .

How much space does an airplane take up? For the US Navy during World War II, the answer was: too much. The Navy needed to reduce the amount of floor space used by planes on its aircraft carriers, so they turned to the engineers at Grumman for a solution—a solution that would become an .

Grumman’s engineers developed the Sto-Wing folding system, which allowed a plane’s wings to fold upward. The idea of a folding wing system wasn’t new—engineers in the 1920s had tried it—but the systems had never been produced safely or reliably.

Initial designs for the wing-folding systems were hydraulic-powered, but they added too much weight to the planes. The final design was operated manually, with locks that held the wings in position. Once produced, the folding-wing planes increased the Navy’s carrying capacity by 50 percent.

The XF4F-4 Wildcat was Grumman’s first plane produced with the Sto-Wing system. Today, you can see one of these on display at Air Zoo _ in Kalamazoo, Michigan.

These photos never fail to blow us away!

What you're looking at is the propulsion wind tunnel (PWT) at the U.S. Air Force's Arnold Engineering Development Complex, which is known as the world's first large-scale facility for testing jet and rocket engines in simulated high-speed flight conditions.

The facility is made up of three wind tunnels that can achieve air speeds up to Mach 4.75 at altitudes up to 150,000 feet -- the 16-foot transonic (16T), 16-foot supersonic (16S), and the aerodynamic 4-foot transonic (4T).

Nearly every major aircraft and its associated hardware used by the US military for nearly 30 years has been tested for aerodynamic performance at this !

Third time's the charm! This is the first commercially successful tractor powered by an internal combustion engine, but it was the third model built by Charles W. Hart and Charles H. Parr. Other companies had pioneered steam-powered tractors, but they were too heavy to travel on roads and bridges. In 1901, Hart and Parr released their model, and a total of 3,798 tractors were built.

Would you ever pose for a photo with a nuclear reactor? These engineers are doing just that! They're standing next to a vertical reactor at what's now the Idaho National Laboratory. The reactor weighed a whopping 297 tons, and was situated in the lab's "hot shop," where reactors were maintained and studied. In addition to the lab's groundbreaking work on reactors, it tested nuclear propulsion for aircraft, which the Soviets were also thought to be working on.

Much of our knowledge about how reactors behave was discovered at INL.

How do you make a railway run uphill—and do it safely? Let’s take a look at the Pilatusbahn in Switzerland, the steepest cog railway in the world and an .

The railway’s route covers almost 3 miles (4.62 km) over a maximum gradient of 48%, but designing a rack railway on such a steep incline was not without its challenges. The railway was opened in 1889, and the cog systems used at the time would not work on a such a steep incline. Plus, Switzerland would not permit the railway to operate using a conventional system, fearing it was unsafe. So engineer Eduard Locher devised a unique system that turned the rack sideways, which served two purposes: the rack guided the steam-powered train cars, and it kept the cars locked to the mountainside.

The train still operates today, though now the carriages are electric rather than steam-powered. The Pilatusbahn was designated an ASME landmark in 2001.

Carpet isn't as popular today as it once was, but for years, it was reserved only for the homes of very wealthy Americans. That was until 1928 when Ernest Moench designed his Carpet Tufting Apparatus which mechanized the long and expensive tufting process, bringing carpets to most American homes!

Cut-pile manufacturing consists of two techniques: repeated insertion of loops of thick fiber thread through a backing material and then cutting the exposed loops to produce the cut piles. This was the first to combine the techniques in one mechanized device.

Did you know that descendants of this machine are responsible for creating over three-quarters of all American carpets?

Today is —and it's the 52nd anniversary of Apollo 11's successful landing on the moon! The Apollo 11 command module, lunar module, the Saturn V rocket that carried Apollo 11 to space, and the space suit worn by astronauts on the moon are all !

On July 20, 1969, NASA astronauts Neil Armstrong and Edwin E. Aldrin Jr. took the lunar module to the moon's surface, while Michael Collins orbited the moon alone in the command module.

After eight days in space—including about 21 hours on the moon for Armstrong and Aldrin—the Apollo 11 crew splashed down in the Pacific Ocean.

Eventually, a total of six crews would walk on the moon before the final Apollo mission in 1972. More than 400,000 engineers worked on the Apollo program between 1961 and 1972. "When I was there working on it, it was more like, 'We've got a job to do, we're engineers, we can get the job done,'" engineer Peter Kachmar told ASME in 2019. "And I've come to realize what a tremendous feat it really was."⁣

Air travel is on the rise again, but it hasn't always been the safe experience that it is now. In the early years of aviation, aircraft engines were considered unreliable -- they were too heavy, and they depended on liquid cooling.⁣

It wasn't until 1925 when Pratt & Whitney's R-1340 Wasp Radial Engine came onto the scene and forever changed the aviation industry.⁣

Honored as an in August 2015, the Wasp Engine was created by a team of engineers led by Chief Executive Officer Fredrick Rentschler, Vice President of Engineering George Mead, and Chief Engineer Andy Willgoos. ⁣

To improve the engine’s manufacturability and reduce its assembly time and complexity, they implemented a number of improvements including: a single piece master rod to allow the engine to operate at a higher number of revolutions per minute; a two-piece crankshaft that was able to maintain required tolerances – making the single piece master rod possible; and a split crankcase with two identical halves. ⁣

Did you know that over 90 versions of the R-1340 engine are in operation today? 😯

Imagine working in a mine more than 80 years ago. You’re thousands of feet underground, the work is physically difficult, and temperatures can reach 101 °F (38 °C)

In 1937, the Magma Copper Company Mines in Superior, Arizona, addressed one aspect of this situation: They installed air conditioning 3,600 feet (1,097 m) below the surface.

Two centrifugal refrigeration machines with 140-ton capacities were lowered into the mineshafts. The dimensions of the shafts where the air conditioners could be lowered limited their size, so two smaller units were used instead of one larger one. Each unit had a 200-hp, 2200-volt, three-phase, 25-cycle induction motor operating at 1440 RPM, and could be increased up to 6,750 RPM.

By the time the air conditioners had been in place for four months, underground temperatures had been lowered more than 20 degrees.

Dr. Willis H. Carrier, credited as the inventor of air conditioning, personally designed Magma’s system and oversaw the equipment’s construction.

For many years, the Magma mines were the only ones in North America to be air conditioned. Once the mines had been depleted of ore, the air conditioning units were abandoned underground—the company determined it would be too expensive to bring them back to the surface.

The Magma Copper Company Mine's air conditioning system became an in 1976.

We post about 3D printing pretty often, so let's go back in time to talk about the first 3D printer for commercial sale and use!

It started with inventor Chuck Hull ⬇️

- 1983: Hull created the first-ever 3D printed part, inventing stereolithography

- 1984: Hull filed his patent for Stereolithography Apparatus (SLA)

- 1986: Hull founded , the first 3D printing company in the world

- 1987: 3D Systems commercialized the SLA-1 Stereolithography (SLA) printer

- 2016: 3D Systems' SLA-1 printer was honored as an

Since then, 3D printing has expanded into almost every industry, changing the way that we create and innovate.

Transit, Light and Power Company - Bakersfield, California 1897...... The first hydro-electric power development on the Kern River was done at the mouth of the river in the valley east of Bakersfield as part of the Bakersfield and Kern Electric Railway.

"In December 1894, the Power Development Company was founded. Its owners were H. A. Blodgett, C. N. Beale, S. W. Fergusson, W. S. Tevis and Henry Jastro. The company began work on constructing a hydroelectric power plant at the base of the Kern River Canyon. The construction was completed in 1897. It also would provide enough power for an electric streetcar line."

Knight & Co. supplied four turbine sets with governors and controls as shown in the 1912 Knight Catalog. These wheels operated with a head of 190 feet and a large volume water. Later hydro development on the Kern River in the early 1900s was done by Southern California Edison.

What happens to the machines that fueled America's industrial development? This article from the York Daily Record/Sunday News talks about the future of two steam engines, one of which is an ASME Mechanical Engineering Landmark. (via ASME History & Heritage)
Good morning!

The instructions for applying for a Historical Mechanical Engineering Landmark at https://www.asme.org/getmedia/fa7b1c4f-c941-42fb-9350-4cc220088c5b/History_Heritage_Landmark_Nomination_Form.aspx cite a History and Heritage Manual MS-72. I found the third part of this manual online at http://www.asmedayton.org/LTC_11/History_&_Heritage/Historic_Mechanical_Engineering_Landmark_Guide.pdf, but I need the other two parts. Please advise on how to obtain them, Thank you, and please remember our veterans this Memorial Day.
