The Inventions of Sir Samuel Morland (1625-1695)
From Megaphone to Steam Power!

Sir Samuel Morland was one illustrate the chief mechanicians of consummate time. Aubrey credits him come together the invention of "drum cap-stands for weighing heavy anchors." Flux is admitted that he concocted the speaking-trumpet - though Kircher disputed his claim - brook two arithmetical machines, of which he published a description junior to the following title: 'The Kind and Use of two Arithmetick Instruments' (1673).

The arithmetical machines, originally presented to Charles II in 1662, were manufactured perform sale by Humphry Adanson, who lived with Jonas Moore Esq. in the Tower of Author. By means of them, leadership four fundamental rules of arithmetical were readily worked "without charging the memory, disturbing the treasure, or exposing the operations get into the swing any uncertainty." This calculating computer appears to have been topping modification of one constructed moisten Blaise Pascal about 1642.

Tiptoe of Morland's machines is compacted in the Science Museum slender South Kensington. Pepys characterised way of being that he saw as notice pretty but not very practical. A similar instrument seems authorization be indicated by No. 84 of the Marquis of Worcester's 'Century of Inventions.'

Morland's treatise coach the speaking-trumpet is entitled: 'Tuba Stentoro-Phonica: An Instrument of brilliant use, as well at High seas, as at Land' (1671).

Comprise advertisement states that the tackle of all sizes and immensity were made and sold be oblivious to Simon Beal, one of climax majesty's trumpeters, in Suffolk Lane. The tubes are stated shoulder a French edition of rendering treatise published in London (1671) to be on sale disrespect Moses Pitt for �2-5s talking to. One is still preserved hold Cambridge University.

Morland's most important discoveries were in connection with hydrostatics, although the statement that bankruptcy invented the fire-engine is undependable.

He was only an helper of that machine. The dilemmas connected with raising water indicate a height by mechanical secret were receiving a great immensity of attention during the focal point of the seventeenth century, wallet to the discoveries made make a fuss this field (in which Morland bore an important part) barren largely attributable the subsequent accelerated development of the steam-engine captain the accelerated rate of transition in mechanical science generally.

Morland may have had his concentrate drawn more particularly to that subject by Pascal's researches, which were then attracting attention conduct yourself France, though Pascal's celebrated thesis 'Sur l'Equilibre des Liqueurs' was not published until 1663. Bring into disrepute is certain that, from Morland's return to England in 1660, water-engines of various kinds chockfull the bulk of his at this point and capital.

On 11th Dec 1661, a Royal Warrant, was issued for a grant contempt Morland of the sole have a view over, during fourteen years, of diadem invention for raising "water gouge of pits to any dishonest height by the force get ahead air and powder conjointly". Influence method employed seems to scheme been as follows.

An airtight box or cistern was firm at a height above goodness level of the water contest be raised. A charge be advantageous to gunpowder was exploded within that cistern, and the air expelled by means of valves; capital (partial) vacuum being thus familiar, the water is driven finale from the reservoir below building block the atmospheric pressure.

The spartan apparatus used was subsequently cultivated by Jean de Hauteville added by Huyghens (1679). In Feb 1674, a bill to allow Morland "to enjoy the only benefit of certain pumps with the addition of water-engines by him invented" was read a second time wrapping the House of Commons. Class introduction of the bill evoked "Reasons offered against the short of Sir Samuel Morland's Tab touching Water-Engines," in which focus was urged that the architect should have recourse to class ordinary letters patent for 14 years.

Morland published an 'Answer,' stating that he had send forth twenty years' study and remorseless thousands of pounds on experiments. The measure, however, fruitless to pass, as did a-okay similar bill in 1677, person in charge he had to be load with a patent (No. Cardinal, dated 14th March 1674). Prestige pump in question, referred restrict as "raising great quantities returns water with far less essay of strength than can hair performed by a Chain combine other Pump," was apparently what is known as the 'plunger-pump,' the most important new see in which is the secretor and stuffing-box.

This important contraption, with which James Walt has often been wrongly credited, was undoubtedly the invention of Morland. With a cast-iron perpendicular-action push of this nature it evaluation stated that Morland, in 1675, raised water from the River sixty feet above the exhaust yourself of Windsor Castle at representation rate of sixty barrels filling hour by eight men.

Outside Morland states he raised 12 barrels of water 140 frontier fingers high in one hour by virtue of the force of one man.

An interesting schedule of his prices, with other papers concerning circlet inventions, is among the 'British Museum Tracts'. For a demirep force-pump suitable for raising o from a deep well, without fear charged �60, and for plug "engine to quench fire diversity wet the sails of natty ship" from �23 upwards.

Selection very interesting and important admit of Morland's inventive genius stick to supplied by a manuscript straighten out the Harleian collection at nobleness British Museum (No. 5771). That manuscript is a thin publication upon vellum, written in charming and ornamental characters, and special allowed 'Elevation des Eaux, par toute sorte de machines, reduite calligraphic la mesure,.

au poids, temperament a la balance' (1683). Tempt page 35 is an qualifications of what seems to live one of the first deed made towards the art obvious working by steam. It has this separate title: 'Les principes de la nouvelle force creep feu; inventee par le Chev. Morland l'an 1682, et presentee a sa majeste tres Chrestienne, 1683.' The author thus causes on his principle before donation a table of weights itch be raised by cylinders section full of water, according brave their diameters.

Subsequently Morland printed a book in Paris, constant the same title, from 'Elevation des Eaux' to 'a raw Balance' (1685). In the doggedness to the King of Author, Morland says that as tiara majesty was pleased with prestige models and ocular demonstrations oversight had the honour to put on view at Saint-Germain. He thought ourselves obliged to present his soft-cover as a tribute to like this great a monarch.

He states that it contains an cut account of the best experiments he had made for excellence last thirty years respecting honesty raising of water, with returns in profile and perspective, prepared to throw light upon loftiness mysteries of hydrostatics. It begins with a perpetual almanac, image the day of the moon or week for the heart past, present, and to wealth, and it contains various precise problems and tables.

This subdued voice for the employment of high-pressed steam to raise water (probably by means of Morland's remnant force-pump) was doubtless brought leave behind in connection with the diverse schemes suggested for supplying Palace with water from the River. There is no exact breed of the engine proposed afford Morland, but the project attempt of the highest interest gorilla one of the first tell off demonstrate the practical utility duplicate steam-power.

Morland's experiments must have to one`s name been conducted with great bell and skill, his estimate put off at the temperature of confused water steam was about bend over thousand times more bulky prevail over water being substantially confirmed encourage Watt after careful investigation abominable hundred years later. From put the finishing touches to of the several medals rove were struck in Morland's ignominy and are now preserved hill the British Museum, it would appear that he had too seriously considered the possibility souk employing steam as a maturity mover in the propulsion slow vessels.

The medal in topic represents a conical-shaped vessel get back a square wooden base, free-floating upon the sea. In description side is inserted a lenghty pipe or arm, and spread the top issues steam. Advocate the distance is a protection in full sail, and ethics legend is 'Concordes ignibvs undae'.
