Walter hunt sewing machine

American mechanic and inventor (–)

Walter Hunt (July 29, – June 8, ) was an Americanmechanical engineer. Through the course of his work he became known for being a prolific inventor. He first became involved with mechanical innovations in a linseed producing community in New York state that had flax mills.

While in New York City to promote his inventions he got involved in inventing the streetcar gong that was used throughout the United States. This then led him to invent other useful items like the safety pin and sewing machine.

He invented the precursor to the repeating rifle and fountain pen. About two dozen of his inventions are used today in basically the same form as he had patented them. In spite of his many useful innovative creations he never became wealthy since he sold off most of his patent rights to others at low prices with no future royalties. Others made millions of dollars from his safety pin device.

Early life and education

Walter Hunt was born July 29, , in the town of Martinsburg, in Lewis County in the state of New York. He was the first born child of Sherman Hunt and Rachel Hunt. He had twelve siblings. Hunt received his childhood education in a one-room schoolhouse. Hunt was muscular, tall and slender with a ruddy complexion.

He married Polly Loucks in and they had four children. Hunt went to college and earned a master's degree in masonry in at the age of ^[2]

Mid life

Hunt traveled to New York City in to get money for one of his inventions. While there he witnessed an accident where a horse-drawn carriage ran over a child.^[3] The accident event motivated him to come up with a metal bell that was operated with a hammer that could be controlled by one of driver's feet without letting go of the horse reins.

Hunt patented his new innovation on July 30, He promoted his concept to many prospects and eventually was able to sell his foot operated coach alarm mechanism idea to the stagecoach operators Kipp and Brown. Hunt's innovation was soon adopted by most public horse-drawn vehicles throughout the city.^[2] Hunt's coach alarm was further developed and used throughout the United States.^[9]

Inventions

Hunt was a prolific inventor.

From to , while earning a living in the real estate field, he invented a fire engine, an improvement for hard coal-burning stoves, the first home knife sharpener,^[10] and a restaurant steam table apparatus. He also invented the precursor of the Winchester repeating rifle^[13][14] and the forerunner of the American fountain pen as used in the twentieth century.

Additionally, Hunt invented a flax spinner, an improved oil lamp, artificial stone, the first rotary street sweeping machine,^[10]mail sorting machinery, velocipedes, and ice plows.^[20][21] He also made improvements to guns, cylindro-conoidal bullets, ice-breaking wooden hull boats, paraffin oil candles, velocipedes, machines for making rivets and nails, and self-closing inkwells.

He also invented the Antipodean Performers suction-cup shoes claimed to be used by circus performers to ascend up solid side walls and walk upside down across high ceilings.^[20][25] He did not realize the significance of many of his inventions when he produced them and sold off most of his patent rights to others for low prices making little for himself in the long run.^[26] In the twentieth century many of his patented devices were widely used everyday common products.^[3][27]

Sewing machine

He developed the first modern feasible operating sewing machine^[20] sometime between the years and at his Amos Street shop that was up a narrow alley in Abingdon Square at the borough of Manhattan in the city of New York.^[3] He manufactured and sold a few of these machines at the time.^[21] He never initially patented the mechanical device he created that used a lockstitch for sewing.

It had a characteristic of an eye-pointed needle and used two threads whereby one thread passed through a twisted loop in the other thread and then both interlocked.^[32] The uniqueness of this was that it was the initial time an engineer or technician inventor had not imitated a single stitch done by hand and used two interlocking threads at a seam.

He used a technique for sewing which was revolutionary at the time. The eye opening was near the point of the needle and operated on a vibrating arm and a loop was formed under the cloth by this thread through which a shuttle, reeling off another thread, was forced back and forth making an interlocked stitch. Hunt completed his working model before he showed it to anyone.

Hunt sold one-half the patent rights in to businessman and blacksmith George A.

Arrowsmith who never manufactured it to sell.^[36][37] He instead had Hunt's wooden version duplicated in iron by Adoniram, Hunt's brother. Adoniram was a skilled mechanic and duplicated the original wooden version. It performed better because no splinters of wood impeded the passage of the cloth.

Arrowsmith had no interest patenting the sewing machine then and had decided to postpone that step for a later time. He gave as reasons for not procuring a patent that 1) he was busy with other businesses then; 2) the expense of getting the appropriate drawings and paperwork together to register a patent was more than he could afford and; 3) the difficulty of introducing the new sewing machine into public use, saying it would have cost two thousand (equivalent to $61, in ) or three thousand (equivalent to $91, in ) dollars to start the sewing machine business.

Had he seen the newspaper article titled Sewing by Machinery of December and January that was in many nationwide newspapers he may have applied for a patent right away,^[40] because it said that a mechanic of Rochester had invented a machine for making clothes which would thereafter take the place of fingers and thimbles.^[42]

Hunt did not seek a patent for his sewing machine at the time because he worried it would create unemployment with seamstresses.

History records show that his wife and daughter advised him against marketing his sewing apparatus.^[45][46] Hunt's daughter Caroline operated a corset-making shop with twelve seamstress ladies and was watching out for their interest and thousands of other seamstresses.^[27] This ultimately led to a court case in when the lockstitch sewing machine concept was applied for by Elias Howe in a patent application.^[48] Hunt submitted his initial application for his sewing machine on April 2, Records at the Supreme Court show Hunt's invention was made before Howe's machine and the Patent Office identified Hunt's preexistence but it did not issue a patent to him for this.^[49] The reason was because he had not filled out the proper paperwork for a patent before Howe's paperwork application and had abandoned the design experiment of the s.

Hunt acquired public acknowledgement for his invention, however Howe's official patent remained lawful because of the technicality of the timing of the paperwork. Isaac Singer arranged to give Hunt $50, (equivalent to $1,, in ) in installments for his sewing machine design in in order to clear up the patent confusion about sewing machines, but Hunt died before Singer was able to consummate the agreement.^[2][3][45]

Safety pin

Hunt thought little of the safety pin, his best-known invention.

He sold his patent of it for $ (equivalent to $14, in ) to W R Grace and Company, to pay a draftsman he owed $15 to (equivalent to $ in ).^[3] J.R. Chapin pressured Hunt to pay off what was due to him for the drafting work he had done on previous inventions that needed patent drawings for application submissions.

Hunt came up with the safety pin ("C") in through experimentation with high tension wire.^[3][20][52] His invention was an improvement on the current way clothing items were attached together before because of a protective clasp ("D") at the end and a coiled wire design ("B") with a spring tension on the pointed end leg ("A") to keep it in the protective clasp even if the pin device was moved around.

The basic design is the same in the twentieth century as when Hunt came up with the device in the nineteenth century and is manufactured inexpensively now.^[53] W R Grace and Company made millions of dollars profit off the product.

Other inventions

One of Hunt's popular inventions was a paper shirt collar.

This time he sold the patented design and negotiated for royalty payments, but the item only became popular after he died.^[3] The unusual item was first put on sale in New York City in and used then mostly for stage purposes. In time it became fashionable and the general public then started using them. High production of the item came about and at one time there were as many as forty factories making paper collars in the United States.

The manufactured output in became , that were sold to the general public.^[55]

Hunt often used the legal services and patent research work of Charles Grafton Page, a certified patent lawyer who had worked at the Patent Office before, when seeking a potential patent for one of his inventions.

His inventions covered a wide variety of fields and subjects. About two dozen of Hunt's inventions are still used in the form in which he created them over one hundred years ago.

Later life and death

Hunt created numerous usable everyday inventions in his lifetime, however he never became independently wealthy from them.

He died of pneumonia at his place of business in New York City on June 8, ^[2] He is interred in Green-Wood Cemetery at Brooklyn, New York.^[58][59] His grave is marked by a small red granite shaft about a hundred feet from Howe's massive bust monument.^[60]

Legacy

Hunt was inducted into the Inventors Hall of Fame in for the safety pin invention.^[61][62] Many of Hunt's invention ideas are in actual use today and are basically the same device as when he patented them more than a hundred years ago.

Some of those others besides the safety pin and sewing machine^[63] are a device which regulates the amount of liquid that comes from a bottle with each tilt, a bottle stopper, springy attachment for adjustments to belts and suspenders, and a nail making machine.^[60][65]
