The coal is dropped into a hopper by a grab.
A is the feeding-hopper, on the same principle as is used in blastfurnaces.
The dressed ore is introduced through a "hopper" at the top, and exposed to a moderate oxidizing flame until a certain proportion of ore is oxidized, openings at the side enabling the workmen to stir up the ore so as to constantly renew the surface exposed to the air.
In the neighbourhood are the Alachua Sink, Payne's Prairie, Newman's Lake, the Devil's Mill Hopper and other objects of interest.
Here they are discharged (washed and freed from any adherent soil) into an elevator, which carries them up to the top of the building and delivers them into a hopper feeding the slicer.
This hopper was divided into two parts by vertical division plates, against the bottom edge of which the knives in the disk forced the roots and sliced and pulped them.
The canvas was laid in a hopper barge and there filled with the concrete and sewn up. The enormous bag was then dropped through a door in the bottom of the barge upon the breakwater foundation.
7 and 8, of a solid column of lumps of fuel, ore and limestone, which are charged through a hopper at the top, and descend slowly as the lower end of the column is eaten off through the burning away of its coke by means of very hot air or " blast " blown through '?
The salt is conveyed to the furnace by a chain of buckets running on the pulley (g), and passing into the hopper (h), and through the pipe (i) is mixed with the proper amount of acid supplied by the pipe (f).
The tea is fed into a hopper, which has a large opening at the bottom, and this opening is entirely closed by two cylindrical brushes, which are mounted end to end on a horizontal shaft.
As they revolve these brushes engage the tea in the hopper, draw it out by degrees, and drop it into a compartment of a circular drum which hangs on one end is placed in the weights-pan of the balance, and is the only loose weight used with the machine.
When it is desired to use the machine, a 4-lb bag is placed under the orifice of the hopper upon the goods-pan of the balance, and the slide rods are thrust back by hand till they are held by their detents, and the sugar flows rapidly into the bag.
The sugar is run into a conical hopper and is delivered into the open mouth of a bag which is placed on the goods - pan of a balance.
The hopper is carried on two knife - edges, one on each side, and is prevented from tipping over fore and aft by a pair of parallel motion bars on each side.
The knife-edges on which the hopper rests are on two hori - zontal levers, one on each side of the hop From the Notice issued by the Standards Department per.
Sugar Weighing M the frame of the ma chine, and transmit the weight of the hopper by means of an intermediate lever and a vertical rod to the indicator lever.
When a charge of coal is dropped into the hopper, the bell-crank lever receives a violent jerk from the shackle of the flitch-plate, and this jerk by means of suitable mechanical arrangements throws a pinion on the cam shaft into gear with a wheel on a counter shaft From the Notice issued by the Standards Department of the Board of Trade, by permission of the Controller of H.M.
The cam shaft and the cam then begin to revolve, and the flitch-plate is gradually lowered till the knife-edge bearings of the hopper are received on the knife-edges of the main measuring levers, and the load is then weighed by the levers and the spring-balance.
Shortly after this is done the mechanism at the back of the hopper automatically opens the doors at the bottom of the hopper, and the coal drops out.
The rotation of the cam shaft continues till the cam has again heaved up the flitch-plate, when the pinion on the cam shaft is thrown out of gear with the wheel on the counter shaft, and the cam remains steady till another charge of coal is dropped into the hopper and the action is renewed.
The coal when dropped out of the hopper runs down a shoot into a receptacle, from whence it is lifted by a Jacob's Ladder and distributed to the boilers, &c., of the factory.
G is the feeding-hopper for the anthracite which is usually employed in this kind of producer.
The seeds and nuts are then decorticated (where required), the shells removed, and the kernels ("meats") converted into a pulpy mass or meal (in older establishments by crushing and grinding between stones in edge-runners) on passing through a hopper over rollers consisting of five chilled iron or steel cylinders mounted vertically like the bowls of a calendar.
The ore in fine powder is fed in at the top, through a hopper, in a regular thin stream, by a pair of rollers, and in falling lodges on the flats of the bars, forming a talus upon each of the height corresponding to the angle of rest of the material, which is, however, at short intervals removed to lower levels by the arrival of fresh ore from above.
Diameter, which were fitted with knives and made 140 to 150 revolutions per minute, under the hopper which received the roots.
The charges of coal fall into the hopper with a heavy shock, and in order to save the knife-edges there is a strong pin in each side of the hopper below the knife-edge, which, before the charge of coal is dropped into the hopper, is acted on by a strong horizontal flitch - plate, which heaves the hopper off the knife-edges and relieves them from the shock.
In the first two cases a scoop, filled with coal from an overhead hopper carried by the travelling machine, is made to enter the retort and is turned over; the operation is then repeated, but this time the scoop is turned over in the opposite direction, the coal thus assuming such a position that as much of its under surface as possible is exposed to the heated side of the retort.
The heaving-up of the flitch-plate and hopper is effected by a cam on the end of a horizontal shaft which runs along the back of the machine behind the hopper.
The blanks are charged into a hopper at one end of the furnace and conveyed towards the other end by a revolving Archimedean screw.
The coins are placed in a rouleau in the hopper C and the lowest one is pushed on to the pan B by a slide not shown in the figure.
Hopper: a True Life (1853), The Progress of Religious Ideas through Successive Ages (3 vols., 1855), Autumnal Leaves (1857), Looking Toward Sunset (1864), The Freedman's Book (1865), A Romance of the Republic (1867), and Aspirations of the World (1878).
The pan proper is surmounted by a great cone or hopper called a curb, to provide for the foaming up of the boiling mass and to prevent loss from overflowing.
Knives are arranged around their circumference in such a way that the hopper feeding them presents an annular opening to the disk, say 7 ft.
