In the late s, Lester J. Hendershot built his Hendershot Generator, largely through simple trial and error. He wove together a number of flat coils of wire, and placed stainless steel rings and sticks of carbon, and experimented with permanent magnets in various positions. To his surprise, the device actually produced current. The generator raised considerable attention at the time. Detroit, Mich, Feb. Lester J. Hendershot, the inventor, and his associate.
This block test was witnessed by Major Thomas G. Lanspier, Colonel Charles A. Lindbergh and others. It was explained today that the model used in the demonstration was a much smaller machine than an actual working motor capable of developing enough power to lift and propel an airplane. Stout said. Stout said the model he saw was about the size of the tiny motors used in vacuum cleaners. Stout continued. Such sources of cheap and inexhaustible power, of course, never have been reached since Tesla.
Neither Colonel Lindbergh nor Major Lanphier would express themselves at length on the test they witnessed yesterday. Major Lanphier admitted, however, that they were experimenting with it and referred all questions to Hendershot. William B. Although Hendershot was on his way from Selfridge Field today and is not expected home until tomorrow, his wife told of his conception of the machine and how the miniature model was constructed from the parts of a worn out radio which had been given to the inventor by his uncle.
His 4-year old boy had built a small airplane at that time and was considerably chagrined because it would not operate. The father was disturbed too, so he told his son he would build an airplane which would work. The result of that was the fuelless machine. When the miniature motor model had been constructed, Hendershot built a small airplane and placed the machine in it.
A switch was turned and immediately the propeller began to move. For several weeks the little motor and the airplane rested upon a small table in the living room of the Hendershot home, which faces an unpaved street near the railroad tracks.
One day D. He immediately became enthusiastic and a few weeks later he and Hendershot were at Selfridge Field where permission was been granted to build a model large enough to operate an airplane.
Hendershot, who is only 29 years old, was born in Hyndmann, Pa. His schooling has not been extensive, although he spent a few months several years ago at Cornell University, where he took a few courses in mechanics.
He has been a fireman and an engineer on the railroad, has worked in the mills near Pittsburgh, has inspected concrete and done electrical work.
During the war he was a bugler with a machine gun company, but did not get overseas. According to his mother, he has always been interested in mechanics and when a child he would insist upon taking his playthings apart.
It required only a few weeks for him to construct the miniature model of his fuelless motor, although he worked day and night during that time. He had a crude workbench in the cellar of his home, which was placed near the furnace, where it was warm.
Early in the morning he would be there, tinkering about, and late at night he still could be found there. Hendershot first came to Bettis airplane field in McKeesport between two and three years ago, and soon afterward brought one of his motor models to the officers of the field for inspection. The fuelless motor works somewhat on the principle of a compass, and the original model would always operate when pointing north or south, as does the compass, but would not move when pointed east or west.
Young Hendershot worked nearly two years to overcome this defect, and finally he brought a motor to the Bettis field that appeared to be working perfectly. This motor was installed in a small model airplane and the plane flew, but owing to the failure to rig it properly, it crashed to the ground during one of the experiments.
Constantly improving the motor, Hendershot finally interested D. Barr Peat, manager of the Bettis Field, in his invention. After a short time several capitalist were interested, and a few weeks ago the motor was taken to Detroit by Hendershot and Peat for an exhibition. While no person at the field was in position to say authoritatively, it was stated that the capitalists who become interested in the Hendershot motor have about completed their arrangements for the purchase of the invention, or for controlling its production.
The fuelless motor, it is said, appears to have tremendous power and easily made between and revolutions per minute on several occasions while being tested at the field. Pilots and mechanics believe it to be the greatest invention of the age, and all appear sure it will be a practical success as an airship motor. It was stated at the field that the inspection of the motor by Colonel Lindbergh was made in the interests of the capitalists who were arranging to purchase the invention.
Hendershot, the inventor, and D. Barr Peat, have been quietly working on an experimental model. Why this generator acts as it does, where the energy comes from that transforms it into power, Major Lanphier was not prepared to say beyond quoting Hendershot. While unwilling to describe it in detail until pending patents have been received, Major Lanphier told a little about it.
The first model consisted of a ring magnet less than three inches in diameter. Around the magnet were coils rigged as only Hendershot knows how to rig them, and another set of coils pass through the center of the ring. The larger model which has not yet been hooked to a motor that will deliver power to a crankshaft, Major Lanphier himself helped build. The second model is built around a ring magnet, the outside diameter of which is seven inches and the inside diameter six inches.
Representative M. Hendershot of West Elizabeth, Pa. A Congressional patent gives the patentee full protection for 17 years. At that time in some quarters it was regarded with skepticism. The motor, according to its inventor, is without visible means of power.
It obtains its initial impulse, Hendershot maintains, from a precharged magnetic core, and its secondary and greatest power impulse by magnetic induction from the earth. Hendershot today said several of his motors had been built here, and that one, which developed 60 horsepower, had been in operation for two weeks without recharging the magnetic core. Mildly indignant because the manner in which his fuelless motor gains its power had been misrepresented in dispatches from Detroit and Washington, Lester J.
The fuelless motor was not his objective, he explained, at the time he began his experiments some three years ago, when he first became interested in aviation. But it must be set before each flight, and is not always reliable. I now have a motor built on that principle that will rotate at a constant speed, a speed predetermined when the motor is built. It can be built for any desired speed, and a reliable constant speed motor is one of the greatest needs of aviation.
The main secret of Mr. He says there is no heat, because magnetic forces are cold and the motor is stopped only by breaking the magnetic field in the windings.
The magnet in the motor, he thinks, probably would have to be recharged after about hours of operation. Hendershot declares that one of his motors, complete and ready to be installed in an airplane would weigh little more than four ounces for every horsepower it developed, while the best of the gas engines now built weighs about two pounds per horsepower. Hendershot says that altitude would not affect the efficient operation of his motor, for the magnetic influence of the earth has been found to remain the same as high as man has ever reached.
He said that the same principle which made his original model operate only when it was placed in one direction, north and south, will be developed so that it will provide a compass that will always indicate true north. Navy Office in San Pedro, California. The letter accused scientists who had earlier belittled his efforts of now repeating his statements word for word.
The submission was made by Force Research, a group of some twenty Californians who, to quote the proposal, were,.
Organized by Lloyd E. Daniel Fry, who a few years earlier had written about his incredible contact with an Unidentified Flying Object in his classic, The White Sands Incident. The proposal provided the names of twenty-two persons including businessmen, attorneys, contractors, publishers, and engineers who had witnessed the generator in action, including a Colonel Lanphier, now retired.
The Force Research project came to an end in , when Lester Jennings Hendershot, his dream of providing the world with free energy still unrealized, committed suicide.
Also see www. The inventor states that he took first inspiration from a statement made by Tesla in an lecture:. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic — and this we know it is, for certain — then it is a mere question of time when men win succeed in attaching their machinery to the very wheelwork of nature.

In modern EE courses, Electromagnetism is barely explained in depth enough. USPO has never been any help to any RE inventor with their Political Agendas and intentions in keeping the citizen as a overworking-overspending-overtaxing slave for max profitting to the government or greedy corporate elites, who will do anything to shutdown any concept of harnessing free energy.
You try and build a generator house from the stream in your back yard, and the EPA shuts it down. I see Lester Hendershot applied for a patent on his fuel less generator but did he ever get the patient? If he did what is the patent number? Near a haff doller each kwh. Send my email to some One please.
My job is a elektrisk man. Bless evry One. Thank Bjarne Larsen Denmark. Interesting but a bit complicated. It was free… in the air so to speak… I will always remember the racket it made as he tuned the sound away and the light came on… no one can take that away from me… the Government will never let you live off the Grid so to speak… it will be interesting if this even gets published… Michael James Hendershot.
It is impressive to hear from a relative, a son.
Lester Hendershot’s Magnetic Field Motor
Hendershot The Lester J. Referring to hendershot5. Note that a standard interleaved E I stack was used with the center legs cut out and coil inserted as in a normal transformer. It seems Hendershot may have used this flux switching of the earth magnetic field to generate a small signal as proof of invention, with the coils 19 and 25 being the output coils. Hence the need for N-S alignment along the length of the device.
