Inventions of Ben Franklin:

  • The Lightning Rod 
  • The Franklin Stove 
  • The Bifocals 
  • The Odometer 
  • The Franklin Bells

Invention 1: The Lightning Rod 

The invention of nan lightning rod by Benjamin Franklin is considered 1 of his astir important contributions to subject and technology. The lightning rod is simply a instrumentality that is designed to protect buildings and structures from harm caused by lightning strikes. He conducted a bid of experiments pinch energy successful nan 1740s and 1750s, which led to nan invention of nan lightning rod. He realized that lightning was a shape of energy and that it could beryllium directed distant from buildings and structures by intends of a metallic rod. 

History: Franklin initially mentioned his connection for a “pointed rod of iron” that would beryllium fastened to nan apical of a building to take sides it from lightning strikes successful a 1749 missive to a French scientist. Franklin besides described his studies pinch energy successful nan letter. In his 1751 book, “Experiments and Observations connected Electricity,” he later published a much in-depth relationship of his experiments and nan creation of nan lightning rod. 


  • Protection from lightning harm to houses and different structures
  • lowered threat of occurrence and different lightning-related dangers
  • More persons wrong nan protected building aliases building are safe


  • The value of installation is precocious for immense structures aliases buildings.
  • The request for regular upkeep and inspection to make judge nan lightning rod is successful bully moving order
  • The chance that a lightning onslaught whitethorn harm nan lightning rod directly, decreases its expertise to shield a building aliases different structure. 

Invention 2: The Franklin Stove 

Benjamin Franklin created nan Franklin Stove successful nan precocious 1700s.

Compared to accepted fireplaces, nan stove’s creation allowed it to pain little wood while producing much heat.

History: When Franklin released a pamphlet titled “An Account of nan New Invented Pennsylvania Fireplaces” successful 1742, nan Franklin Stove was first used. He discussed nan creation of nan stove, its benefits, and really it could beryllium built successful nan brochure. To thief group understand really nan stove operated, he besides supplied pictures of it.


  • Since nan Stove was much effective than accepted fireplaces, little wood was utilized to make nan aforesaid amount of heat. People who lived successful colder climates, wherever wood was often costly and scarce, benefited from this.
  • Additionally, nan stove was created to beryllium safer than accepted fireplaces. Its covered beforehand kept sparks from escaping and igniting a occurrence wrong nan space.
  • In bid to modulate nan amount of power produced, nan stove besides had a flue that could beryllium changed. This made it simpler for group to power nan somesthesia successful their houses.


  • The stove’s somewhat higher building costs compared to accepted fireplaces would person been a detriment to some.
  • The stove whitethorn not person been arsenic well-liked by group who preferred beauty to usability because it was not arsenic aesthetically pleasing arsenic accepted fireplaces.

In nan beginning, he alternated betwixt 2 different lenses, 1 for region and 1 for reading, depending connected nan task astatine hand. This inconvenienced him, truthful he started experimenting pinch really to merge nan 2 prescriptions into a azygous lens. Franklin yet devised a creation pinch a wider area for region imagination and a half-moon-shaped portion astatine nan bottommost of nan lens for reading. The lenses would past beryllium divided into 2 sections, which he would power fuse together.


  • Presbyopia, a upset that limits nan eyes’ expertise to attraction connected adjacent objects, is made much convenient for group by nan elimination of nan request to move betwixt 2 sets of glasses.
  • Additionally, they did distant pinch nan necessity of cocking nan caput backmost to position nan bottommost of nan lens, which tin strain nan neck.
  • Additionally, utilizing bifocals made it simpler to publication and complete close-up tasks for illustration writing, typing, and machine work.


  • Due to nan added disbursal of nan 2nd prescription, bifocals whitethorn costs much than single-vision spectacles.
  • They besides intelligibly separate betwixt nan 2 prescriptions pinch a line, which immoderate group whitethorn find distracting.
  • Because nan eyes must accommodate to nan various prescriptions, bifocals tin besides return immoderate clip to go utilized to.

  • It made it imaginable for surveyors and mapmakers to precisely cipher nan separation betwixt 2 points, which was basal for making precise maps.
  • It was a alternatively easy-to-use, low-cost instrumentality that could beryllium quickly mounted to a wheel.
  • It could beryllium utilized successful galore places because it was a portable device. 


  • The odometer was not peculiarly precise and whitethorn beryllium influenced by things for illustration unsmooth terrain aliases instrumentality wear.
  • Additionally, it could only beryllium utilized to estimate nan region covered by wheels and could not beryllium utilized for different forms of transportation.
  • Franklin’s odometer was besides not good known aliases used, and it took until nan 19th period for odometers to summation popularity.
