Today we’re taking another trip into the NYS Library collections to explore patents! We’re looking at the 1849 patent for the safety pin, invented right here in New York State. Read on for a good story about a deceptively humble invention and why you might need one this spring!
Keeping it Safe
Anyone who has a safety pin knows that it has hundreds of uses. From its roots as a tool for fastening diapers and repairing clothing, the safety pin has become a symbol for protection, good luck, and solidarity. In the 1970s, the punk rock subculture adopted the safety pin as part of its iconic anti-establishment fashions.
For many long-distance runners in the northeast, the warmer months mean it's time to hit the streets for road races, and no road race is complete without safety pins to hold runners’ bibs in place. While there is some (small) controversy in the running community around alternative types of bib pins, the iconic metal safety pin remains the constant companion of choice for many athletes hitting the trails. While Walter Hunt was certainly tuned in to the importance of good design, it’s unlikely that he could have foreseen the popularity of his invention and its many uses!
Walter Hunt: Inventor and New Yorker
Walter Hunt was born in the 1790s and lived and worked in New York. During his life, he invented or refined several household items and tools, including a fountain pen, a knife sharpener, and an ice plough. Hunt is also credited with building one of the world’s first eye-pointed-needle sewing machines, though he did not pursue commercialization.
In the 1840s, faced with paying a debt of $15, Hunt began work on a new invention to help him earn the money. He worked on twisting a piece of metal wire into a device with a spring at one end and a protective clasp for the pin’s point at the other.

A Story in Patents
The concept of a garment pin was not new, and Hunt’s design was not the first contemporary version of the safety pin, either. An 1842 version did not include Hunt’s spring mechanism, the feature that exists in safety pins we're accustomed to using today.
Hunt patented his safety pin on April 10, 1849, and sold the rights for $400. A century later, Hunt’s name would make an appearance in an intellectual property suit brought by Isaac Merritt Singer against Elias Howe, who had patented a similar machine in 1846. Singer attempted to invalidate Howe’s patent by pointing out Hunt’s earlier work, which occurred decades before Howe’s patent was granted. However, since Hunt had abandoned the work without patenting it, Howe’s patent was ultimately upheld.
Patents at the NYS Library
The NYS Library has been a United States Patent and Trademark Resource Center since 1871. A Patent and Trademark Resource Center (or PTRC) is part of a nationwide network of academic, public, and state libraries designated to support the public with trademark and patent assistance.
The NYS Library's patent collection includes nearly everything the United States Patent and Trademark Office (USPTO) has published and distributed, from early material on paper, through microforms and CD/DVDs, up to their current online databases.
Most of the U.S. patent collection is housed on the 7th floor of the NYS Library. The public is welcome to visit and use the U.S. Patent collection. Patrons can use the patent collection for both patentability searches and historical inquiries.
The NYS Library has trained staff who can assist you in learning to use these tools. Appointments are not required to use the patent collection but are recommended if you would like assistance. You can make an appointment on our website.
These two lines open Henry Wadsworth Longfellow’s famous poem “Paul Revere’s Ride.” This year marks the 165th anniversary of the poem, written in April 1860 and first published in the January 1861 issue of The Atlantic Monthly (which came out in December 1860). This National Poetry Month, we're taking a deep dive into the long life of this distinctly American poem.
Longfellow's Reminder
Longfellow was inspired to write his dramatic poem about Paul Revere’s legendary midnight ride after visiting the Old North Church in Boston, MA. Through vivid imagery and rhythmic verses, the poem tells the tale of Revere’s actions on April 18, 1775.
Longfellow likely gathered details for the poem from primary sources though he takes some creative liberties with historical details. For example, he portrayed Revere as a lone hero who single-handedly warned the colonies, when in fact he was part of a larger network of riders.
Longfellow, a prominent 19th-century poet, wrote the poem just before the Civil War, a time of growing division in the United States. According to literary critic Dana Gioia, the poem:
"… was Longfellow's reminder to New Englanders of the courage their ancestors demonstrated in forming the Union. Another "hour of darkness and peril and need," the poem's closing lines implicitly warn, now draws near. The author's intentions were overtly political–to build public resolve to fight slavery and protect the Union–but he embodied his message in a poem compellingly told in purely narrative terms."
Come Along for the Ride!
The NYS Library has in its collections a bound first edition of the January 1861 issue of The Atlantic Monthly which first showcased “Paul Revere’s Ride.”

Transcript: Paul Revere's Ride
Listen, my children, and you shall hear
Of the midnight ride of Paul Revere,
On the eighteenth of April, in Seventy-Five :
Hardly a man is now alive
Who remembers that famous day and year.
He said to his friend, -- “If the British march
By land or sea from the town to-night,
Hang a lantern aloft in the belfry-arch
Of the North-Church-tower, as a signal-light, --
One if by land, and two if by sea ;
And I on the opposite shore will be,
Ready to ride and spread the alarm
Through every Middlesex village and farm,
For the country-folk to be up and to arm.”
Then he said good-night, and with muffled oar
Silently rowed to the Charlestown shore,
Just as the moon rose over the bay,
Where swinging wide at her moorings lay
The Somersett, British man-of-war :
A phantom ship, with each mast and spar
Across the moon, like a prison-bar,
And a huge, black hulk, that was magnified
By its own reflection in the tide.
Meanwhile, his friend, through alley and street
Wanders and watches with eager ears,
Till in the silence around him he hears
The muster of men at the barrack-door,
The sound of arms, and the tramp of feet,
And the measured tread of the grenadiers
Marching down to their boats on the shore.
Then he climbed to the tower of the church,
Up the wooden stairs, with stealthy tread,
To the belfry-chamber overhead,
And startled the pigeons from their perch
On the sombre rafters, that round him made
Masses and moving shapes of shade, --
Up the light ladder, slender and tall,
To the highest window in the wall,
Where he paused to listen and look down
A moment on the roofs of the town,
And the moonlight flowing over all.
Beneath, in the churchyard, lay the dead
In their night-encampment on the hill,
Wrapped in silence so deep and still,
That he could here, like a sentinel’s tread,
The watchful night-wind, as it went
Creeping along from tent to tent,
And seeming to whisper, “All is well!”
A moment only he feels the spell
Of the place and the hour, the secret dread
Of the lonely belfry and the dead ;
For suddenly all his thoughts are bent
On a shadowy something far away,
Where the river widens to meet the bay, --
A line of black, that bends and floats
On the rising tide, like a bridge of boats.
Meanwhile, impatient to mount and ride,
Booted and spured, with a heavy stride,
On the opposite shore walked Paul Revere
Now he patted his horse’s side,
Now gazed on the landscape far and near,
Then impetuous stamped the earth,
And turned and tightened his saddle-girth ;
But mostly he watched with eager search
The belfry-tower of the old North Church,
As it rose above the graves on the hill,
Lonely, and spectral, and sombre, and still.
And lo ! as he looks, on the belfry’s height,
A glimmer, and then a gleam of light !
He springs to the saddle, and the bridle he turns,
But lingers and gazes, till full on his sight
A second lamp in the belfry burns !
A hurry of hoofs in a village-street,
A shape in the moonlight, a bulk in the dark,
And beneath from the pebbles, in passing, a spark
Struck out by a steed that flies fearless and fleet :
That was all ! And yet, through the gloom and the light,
The fate of a nation was riding that night ;
And the spark struck out by the steed, in his flight,
Kindled the land into flame with its heat.
It was twelve by the village-clock,
When he crossed the bridge into Medford town.
He heard the crowing of the cock,
And the barking of the farmer’s dog,
And felt the damp of the river-fog,
That rises when the sun goes down.
It was one by the village-clock,
When he rode into Lexington.
He saw the gilded weathercock
Swim in the moonlight as he passed,
And the meeting-house windows, blank and bare,
Gaze at him with a spectral glare,
As if they already stood aghast
At the bloody work they would look upon.
It was two by the village-clock,
When he came to the bridge in Concord town.
He heard the bleating of the flock,
And the twitter of birds among the trees,
And felt the breath of the morning-breeze
Blowing over the meadows brown.
And one was safe and asleep in his bed
Who at the bridge would be first to fall,
Who that day would be lying dead,
Pierced by a British musket-ball.
You know the rest. In the books you have read
How the British regulars fired and fled, --
How the farmers gave them ball for ball,
From behind each fence and farmyard-wall,
Chasing the red-coats down the lane,
Then crossing the fields to emerge again
Under the trees at the turn of the road,
And only pausing to fire and load.
So through the night rode Paul Revere ;
And so through the night went his cry of alarm
To every Middlesex village and farm, --
A cry of defiance, and not of fear, --
A voice in the darkness, a knock at the door,
And a word that shall echo forevermore !
For, borne on the night-wind of the Past,
Through all our history, to the last,
In the hour of darkness and peril and need,
The people will waken and listen to hear
The hurrying hoof-beat of that steed,
And the midnight-message of Paul Revere.
