Making Skyscrapers Possible—The Otis Lift

The passenger car installed by Elijah Otis on Broadway in 1857 was not as elaborate as this post-Civil War model, but it did the job.

On March 23, 1857 Elijah Graves Otis, a former itinerant Yankee jack-of-all-trades and tinkerer turned entrepreneur installed his first successful commercial passenger elevator in a four story building at 488 Broadway in New York City.  After that, you should pardon the expression, Otis’s fortunes were on the way up as sales for his invention took off. The lift made large scale multi-story industrial and commercial buildings practical.  In a few more decades it would be critical to the development of the skyscraper. 

Otis’s invention was not so much the lift itself—various kinds had been in limited use for decades, mostly operating like over-sized dumb waiters on a block and tackle hoist.  But these lifts were limited by the weight they could handle and wear and tear on the ropes meant that they often crashed when the cord snapped.  His breakthrough was an effective locking mechanism on a traction lift that prevented the platform or car from falling.  His safety elevator soon made all other lift systems obsolete.

Otis was born on August 3, 1811 in the small town of Halifax, Vermont just over the border from western Massachusetts, even at that late date a fairly rustic almost frontier community. His father was a farmer but as a boy he was drawn to the village blacksmith shop where he was fascinated with tools, making things, and tinkering.  He may have served a kind of informal apprenticeship to the local smith who appreciated the hero worshiping attention

Restless and determined to escape the fate of a stone field farmer he left home at age 19 determined to find something better.  Thus began his wandering years marked by a series of jobs and business ventures each requiring the mastery of some new set of skills

He eventually settled in Troy, New York where he worked as a teamster, carefully saved his money, and kept an eye out for opportunities.  He married Susan A. Houghton in 1834 but later the same year contracted a nearly fatal case of pneumonia.  He recovered and the couple had a son, Charles.  By 1838 Otis had saved enough money to buy property on the Green River in the Vermont hills.  He designed and built by his own hands a gristmill on the river.  When that failed to prosper he converted it to a sawmill.  When that didn’t work out, he turned to building wagons, for which he turned out to be highly skilled.  Just as he seemed well established with a prosperous future, Susan died shortly after giving birth to a second son Norbert.

Eight year old Charles was already working alongside his father, but Otis needed a mother for his second son who was still in diapers.  Finding no local prospects, he sold his business and moved to Albany, New York where he found a second wife and a job as a doll maker.  Once again he quickly mastered his new craft but was dissatisfied that in a 12 hour shift he could make only a dozen dolls.  Since he was on piece work he began tinkering with ways to mechanize at least part of the production.  He invented a robot tuner—a lathe that could turn out multiple items following a master pattern.  Although useful in turning out rough parts of doll bodies, both Otis and his employer recognized it was much more valuable for turning spindles used in the production of bedsteads.  From the production of no more than 50 pieces a day on a single lathe, his new process could make 200.  His delighted boss bought his patent for $500, a respectable small fortune

                      Elijah Otis, the classic example of an American tinkerer.

With that cash and his savings Otis boldly opened his own business.  He invented and tried to market a safety brake that could stop trains instantly and an automatic bread baking oven.  Just as the business was beginning to get established the city of Albany diverted the stream he was using to power his mill for its fresh water supply.  He was ruined when he was left with no way to run his machinery. 

Embittered he left Albany for good in 1851 and relocated with his family to Bergen City, New Jersey where he worked as a mechanic, then to Yonkers, New York.

He found an ideal opportunity in Yonkers when he was hired to convert a deserted sawmill into a bedstead factory of which he would become the general manager.  But first there was the problem of gutting the multi-story mill including removing its heavy machinery and tons of debris, which he decided to move to the top floor which he did not plan to use.  Working with his now teenage sons, he devised his safety elevator because the rope-and-pulley hoisting platforms used for such work often failed dramatically.  The system worked perfectly and Otis was able to get his new factory up and running.

But he considered it little more than tinkering on the fly to solve an immediate problem.  Otis did not immediately bother to patent his invention or pursue marketing it.  But when sales at the bedstead factory began to decline, Otis decided to turn back to that safety elevator design.  In 1853 in partnership with his sons he founded the Union Elevator Works which quickly became the Otis Brothers Inc.

The dazzling Crystal Palace, home of the Exhibition of the Industry of All Nations in New York City in 1853.

Now all he had to do was convince potential customers to buy his innovation.  It is always hard to sell people what they don’t know they need.  Otis was frustrated with his initial efforts but in 1853 a grand opportunity presented itself—the Exhibition of the Industry of All Nations, Americas first stab at what became known as a Worlds Fair which was held that year in New York City’s Bryant Park in a Crystal Palace inspired by the London structure of the same name built in 1851 for the original Great International Exposition.

The New York exhibition may have been a pale copy of its British inspiration but it dazzled Americans with displays of the latest industrial and technological innovation.  Walt Whitman in his poem The Song of the Exposition enthused:

... a Palace,
Lofter, fairer, ampler than any yet,
Earth’s modern wonder, History’s Seven out stripping,
High rising tier on tier, with glass and iron facades,
Gladdening the sun and sky-enhued in the cheerfulest hues,
Bronze, lilac, robin’s-egg, marine and crimson
Over whose golden roof shall flaunt, beneath thy banner, Freedom.

Newly inaugurated President Franklin Pierce still reeling from the death of his son in a freak railroad accident on the way to Washington to assume office, managed to bestir himself from the alcoholic stupor he kept himself to come up to New York to bless the opening of the Exposition with Presidential dignity in July of 1853.  A then astonishing 1.1 million visitors attended the fair in the 18 months it was open.

With an audience like that and breathless accounts of the exhibits and doings filling newspaper columns across the nation, Otis got in on the action.  He and his sons constructed a working three story high open platform lift in the Crystal Palace.  To inaugurate his exhibit before record breaking crowds, he enlisted the aid of the nation’s leading promoter and entertainment impresarioPhineas T. Barnum himself.

That's supposed to be P.T. Barnum himself on the upper platform with the sword he just used to cut the rope on Otis's lift platform.

One afternoon at the Fair in 1854 Otis stood on the open platform of his contraption along with several barrels and crates weighing several hundred pounds.  He demonstrated that the platform would lift him and the freight and that it could lower it again.  That in itself did not astonish the audience—they had seen or heard of other lift devices.  But then he brought out Barnum who with much fanfare swung a broadsword severing the hoist rope with the platform still high above the heads of the crowd which gasped in horror.  The platform dropped, but only a few inches—its fall was jarringly but effectively arrested by Otis’s safety break gizmo.  The crowd went wild.  The demonstration was repeated daily—minus Barnum—always with the same satisfying results.

Orders for his commercial lifts began pouring in sales doubled every two years.  But it took three years to persuade a developer to install one for passenger use in a commercial building.  The success of his Broadway installation in 1857 finally led to that market opening up as well.

Otis continued to tinker on improvements, including a three-way steam valve engine, which could transition the elevator between up to down smoothly and stop it rapidly. He wrapped up several other clever improvements in a new 1861 patent, which became the basis for all modern elevators.  Meanwhile the restless inventor returned to his old projects and patented versions of his engineer-controlled railway breaking systemstate of the art until George Westinghouses air breaks decades later and his industrial scale bread baking ovens. 

Then at the age of only 49 and a seemingly limitless future ahead of him, Otis contracted diphtheria and died on April 8, 1861 just as the nation was headed into Civil War. 

His company came into the capable hands of his sons.  Charles, who had tinkered alongside his father for years, became a respected engineer who continued to develop new patents for the company and supervise sometimes complex installation projects.  Younger son Norbert turned out to be a gifted executive who shrewdly guided the growth of the company. 

Although the turmoil of the Civil War somewhat impeded the growth of the company, it took off in the post-war industrial boom and especially with the explosive growth of cities whose crowded central cores demand taller and taller buildings.  The introduction of steel girder frame construction was the breakthrough that led to true modern skyscrapers.  The Otis Elevator company kept up with innovations that made reaching for the stars possible.

The company also developed the escalator.

The familiar Otis name plate is on the floor door sill of almost every elevator you will step on.

Otis Elevator remained in private hands for many years but is now a division of the conglomerate UTC Climate, Controls & Security.  The Otis brand, however, remains the gold standard in elevator construction, installation, and maintenance.
