- Rifle-calibre Maxim Gun
Rifle-calibre Maxim Gun Its rate of firing—770 shots a minute—is at least three times as rapid as that of any other machine gun.
It has only a single barrel, which, when the shot is fired, recoils a distance of three-quarters of an inch on the other parts of the gun.
This recoil sets moving the machinery which automatically keeps up a continuous fire at the extraordinary rate of 12 rounds a second.
Each recoil of the barrel has therefore to perform the necessary functions of extracting and ejecting the empty cartridge,
or bringing up the next full one and placing it in its proper position in the barrel, of cocking the hammer, and pulling the trigger.
As long as the firing continues, these functions are repeated round after round in succession.
The barrel is provided with a water jacket, to prevent excessive heating;
and is so mounted that it can be raised or lowered or set at any angle, or turned horizontally to the left or to the right.
The bore is adapted to the present size of cartridges; and the maximum range is eighteen hundred yards.
The gun can therefore be made to sweep a circle upwards of a mile in radius. - The Duke of Wellington

The Dandy-horse of 1818, the two wheels on which the rider sat astride, tipping the ground with his feet in order to propel the machine, was laughed out of existence. - La France
One of the largest sailing-ships afloat is the French five-master, La France, launched in 1890 on the Clyde, and owned by Messrs A. D. Bordes et Fils, who possess a large fleet of sailing-vessels. In 1891 she came from Iquique to Dunkirk in one hundred and five days with 6000 tons of nitrate; yet she was stopped on the Tyne when proceeding to sea with 5500 tons of coal, and compelled to take out 500 tons on the ground that she was overladen. - Edison with his Phonograph
Edison with his Phonograph In 1878 Mr Edison made a number of phonographs, which were exhibited in America and Europe, and attracted universal attention. The records were made in these on soft tinfoil sheets fastened around metal cylinders. For a while Mr Edison was compelled to suspend work on this invention, but soon returned to it and worked out the machine as it exists practically to-day. It occupies about the same space as a hand sewing-machine. A light tube of wax to slide on and off the cylinder is substituted for the tinfoil, which had been wrapped round it, and the indenting stylus is replaced by a minute engraving point. Under the varying pressure of the sound-waves, this point or knife cuts into the tube almost imperceptibly, the wax chiselled away wreathing off in very fine spirals before the edge of the little blade, as the cylinder travels under it. Each cylinder will receive about a thousand words. In the improved machine Mr Edison at first employed two diaphragms in 'spectacle' form, one to receive and the other to reproduce; but he has since combined these in a single efficient attachment. - Oliphant

- Building Hay stacks
Building Hay Stacks The figure shows how Raymond's Elevator is mounted for stack building. These poles need not be so heavy as when three poles alone are used. They are kept from being drawn over toward each other in elevating heavy loads, by lashing the lower end of each outer pole to a strong sake, driven into the ground obliquely, by first making a hole with a crow-bar. OIt is convenient to place the two pole tripodssufficiently from each other to give room for the stack, or rick,and to allow the wagon to pass within them. The elevator first lifts its load, then carries it along the rope till the man on the load drops it by a jerk of the cord. - Dedericks Hay Press
Dedericks Hay Press One of the best hay presses in the country is one manufactured by L. & P.K Dederick, Albany, and represented in the engraving. It is worked by one or two horses, operating with great force by means of the arms on each side, which ar e connected with toggle joint levers. The hay is thrown in from the upper platform and when reduced to compact bales, by means of the powerful force which this press gives, is taken out at the lower. - Ancient Screw Breech loader

The only reliable mode of proving the strength of Gunpowder is, to test it with service charges in the arms for which it is designed; for which purpose the balistic pendulums, are perfectly adapted - Revolving Barrelled Matchlock
The Chinese of the present day make use of a species of matchlock revolvers, and also of another matchlock, consisting of several barrels, placed on a common stock, diverging from each other, and fired simultaneously. - Queen Elizabeth’s Pocket Pistol
At Dover there is a culverine, presented to Queen Elizabeth, by the States General of Holland, and called Queen Elizabeth’s Pocket-pistol. It is 24 feet long, diameter of bore 4 1⁄2 inches, weight of shot 12lbs.; it was manufactured in 1544, and is mounted on an ornamented iron carriage made in 1827, at the Royal Carriage Department, Woolwich Arsenal. - Quarrels
- Powder Mill
The three ingredients are now ground separately to a very fine powder. The mills which effect this, and incorporate, are so similar, that a description will be given under the head of “Incorporation.” Screening.After being ground in this way, the saltpetre is passed through a slope cylindrical reel, covered with copper sieving wire of 60 meshes to the inch, which, as it revolves, sifts it to the required fineness, being then received in a box or bin underneath. The charcoal and sulphur are likewise passed through similar reels of 32 and 60-mesh wire respectively, and that which remains without passing through, is ground again under the runners. - Pierrier or Paterera
- Onager
Of machines formed on the sling principle, that called Onager may be regarded as typical of all the rest. Its force entirely depended upon the torsion of a short thick rope, acting upon a lever which described an arc of a vertical circle. The lever had attached to its free extremity a sling, or sometimes it merely terminated in a spoon-shaped cavity. When bent back, it was secured by a catch or trigger, and charged with a stone. On starting the catch by a blow with a mallet, the lever described its arc of a circle with great velocity, and projected the stone to a considerable distance. - Onager (Unslung)

- Old Eprouvette Pendulum
The only real use of these eprouvettes is to check and verify the uniformity of a current manufacture of powder, where a certain course of operations is intended to be regularly pursued, and where the strength, tested by means of any instrument, should therefore be uniform. - New Pattern Eprouvette

- Moolik i Meidan
One of the largest cannon now existing is a brass one at Bejapoor, called “Moolik-i-Meidan,” or “The Lord of the Plain.” It was cast in commemoration of the capture of that place by the Emperor Alum Geer, in 1685. Its length is 14ft. 1in., diameter about 5ft. 8in., diameter of bore, 2ft. 4in., interior length of bore, 10ft.; length of chamber unknown; shape of gun nearly “cylindrical;” description of shot, stone. An iron shot for this gun, of proper size, would weigh 1600lbs. It is now lying in a dilapidated circular bastion on the left of the principal gateway of the city. The trunnions are broken off, and there is a ring on each side of it, as well as two Persian inscriptions on the top. It is placed on three heavy beams of wood, packed round with large stones. A number of stone shot, of 2ft. 2in. in diameter, are scattered about. This gun is said to be the heaviest piece of ordnance in the world. It weighs about forty-two tons. - Mons Meg
