Maxim gun
Maxim was reported to have said: "In 1882 I was in Vienna, where I met an American whom I had known in the States. He said: 'Hang your chemistry and electricity! If you want to make a pile of money, invent something that will enable these Europeans to cut each others' throats with greater facility.'"[Malcolm Brow]
100 years of 'Maxim's Killing Machine'
''New York Times'', 26 November 1985.
As a child, Maxim had been knocked over by a rifle's recoil, and this inspired him to use that recoil force to automatically operate a gun. Between 1883 and 1885 Maxim patented gas, recoil and blowback methods of operation. After moving to England, he settled in a large house formerly owned by Lord Thurlow in West Norwood

where he developed his design for an automatic weapon, using an action that would close the breech and compress a spring, by storing the recoil energy released by a shot to prepare the gun for its next shot. He thoughtfully ran announcements in the local press warning that he would be experimenting with the gun in his garden and that neighbours should keep their windows open to avoid the danger of broken glass.
Maxim founded an arms company with financial backing from Edward Vickers to produce his machine gun in Crayford

In his later years Maxim became profoundly deaf, as his hearing had been damaged by years of exposure to the noise of his guns.
Flying machines
Maxim's father had earlier conceived of a helicopter powered by two counter-rotating rotors, but was unable to find a powerful enough engine to build it. Hiram first sketched out plans for a helicopter in 1872, but when he built his first "flying machine" he chose to use wings. Before starting design work, he carried out a series of experiments on aerofoil sections and propeller design, at first using a wind tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft ...

s driving two laminated pine propellers.
Conceived of as a test rig, the machine ran on an length of rail track which Maxim laid down for the purpose at his home, Baldwyn's Park Mansion, Baldwyn's Park in Bexley. The initial intention was to prevent the machine from lifting off by using heavy cast-iron wheels, but after initial trials, Maxim concluded that this would not suffice, and so the machine was fitted with four wheeled outriggers which were restrained by wooden rails outside the central track. In trials in 1894, the machine lifted and was prevented from rising by the outriggers. During its test run, all the outriggers were engaged, showing that it had developed enough lift to take off, but in so doing, it pulled up the track; the tethered "flight" was aborted in time to prevent disaster.[Wragg, D.; "Flight Before Flying", Osprey (1974).] Maxim subsequently abandoned work on it but put his experience to work on fairground rides. He subsequently noted that a feasible flying machine would need better power-to-weight engines, such as a petrol combustion engine.
Captive Flying Machines
To both fund his research into flight and to bring attention to the notion of flight, Maxim designed and built an amusement ride for the Earl's Court exhibition of 1904. The ride was based on a test-rig he had devised for his research, and consisted of a large spinning frame from which cars hung captive. As the machine spun, the cars would be swung outward through the air, simulating flight. The ride was similar to the later Circle Swing
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre. Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a given point is const ...
ride, made popular in the US by renowned roller-coaster designer Harry Traver.
Maxim originally intended to use primitive aerofoils and wings to allow riders to control their flight, but this was outlawed as unsafe. As a result, Maxim quickly lost interest in the project, declaring the adapted ride as "Simply a glorified merry-go-round". Nevertheless, his company built several more rides of various sizes at The Crystal Palace
The Crystal Palace was a cast iron and plate glass structure, originally built in Hyde Park, London, to house the Great Exhibition of 1851. The exhibition took place from 1 May to 15 October 1851, and more than 14,000 exhibitors from around ...

, all of which opened in 1904. Originally, Maxim had intended to build only two, but a lengthy breakdown on the original Earl's Court ride forced him to build more to make the venture profitable. He had plans for further variations of the ride but his disillusionment with the amusement business meant that they were never realised.
Although he expressed regrets about the whole project, the rides were held in high regard within the amusement industry and the Blackpool ride still operates to this day as part of what is now the Pleasure Beach amusement park. Along with the same park's similarly historic river caves, it is the oldest operating amusement ride in Europe. The Flying Machines has the distinction of being virtually unchanged from Maxim's original design. The Blackpool ride's name is now usually abbreviated to the "Flying Machine" or "Flying Machines", although the full name, "Sir Hiram Maxim's Captive Flying Machines", is given at the ride entrance.
In 2001, Disney California Adventure Park opened, featuring the Golden Zephyr, a modern-day recreation of the Traver version of the ride. The ride itself is much smaller than the Blackpool version, with cars swinging out at a much smaller angle. Nevertheless, engineers from Disney visited Blackpool to inspect the Maxim ride (the only example of either version still standing) to help design their ride.
Grahame-White, Blériot, and Maxim Company
In 1911, Maxim headed the newly formed Grahame-White, Blériot, and Maxim Company, founded with the two aviators and two hundred thousand pounds of capital.
He had hoped to produce military aircraft capable of scouting or dropping a bomb, but his failing health and financial difficulties with his other enterprises restricted his ability to develop this enterprise before his death.
Philosophy

This book was addressed to Li Hung Chang (also spelled Li Hongzhang and Li Hung-chang) and endeavoured to address a belief that "The Chinese were generally puzzled as to how it was possible for people who are able to build locomotives and steamships to have a religion based on a belief in devils, ghosts, impossible miracles, and all the other absurdities and impossibilities peculiar to the religion taught by the missionaries

."[''Li Hung Chang's Scrapbook'', Foreword, p. x.]
Maxim held European missionaries in China in low esteem, for reasons described in the scrapbook. He stated "...it was my aim, in compiling for His Excellency a scrap-book with explanatory notes, to put the Chinaman right in this respect. I wished to show that we were not all fools." His scrapbook comprised some 400 pages with 42 illustrations, presenting his views on The Nature of Christianity; Christianity in China; and his conclusions on subjects including Miracles, Spirituality, Faith; and the influence of the Bible on the civilisation of Europe and America. He concluded his scrapbook with an appeal to the Missionaries and his thoughts on the reason for the failure of what he described as "Missionary Propaganda" in China.

. The patent, Hiram claimed, had been issued under the name 'H. Maxim,' and that because of this, his brother was able to stake a claim as the powder being his own. Hudson was a skilled and knowledgeable man, and sold arms in the US, while Hiram worked mainly in Europe. Hudson had success in the States, which caused jealousy from Hiram (he lamented having a "double" of himself running around in the States). The jealousy and disagreements caused a rift between the brothers that would last the rest of their lives.

A woman called Helen Leighton brought a case against Maxim, claiming that he had married her in 1878 and that "he was knowingly committing bigamy" against his current wife, Jane Budden. She claimed further that Maxim had fathered a child named Romaine by her. The case was eventually dropped, being settled for under $1,000 (the original amount asked for was $25,000), and Maxim put behind him the near public humiliation the case caused. In October 1898, Helen Leighton again brought charges against Maxim for bigamy and abandonment in Poughkeepsie, New York. Later in life, he left 4,000 pounds sterling to a Romaine Dennison, perhaps the child Leighton claimed he had fathered.
