93 Marychurch, Joseph, Haverfordwest, South Wales —Manufacturer.
Winnowing-machine. The blast is concentrated, andthe machine occupies but little space. The riddles maybe placed in various positions, to suit different qualities ofgrain; they rise and fall independently of the case, whichmoves only in a lateral direction.
Chaff-cutter, having the fly-wheel placed on a transversespindle on one side of the trough, and giving at the cut-ting end a circular motion to the knives; it has threerollers, all worked by one compound-wheel. The mouth-piece is serrated above and below, and its lower jaw ismoveable, being acted upon by a flexible lever workingfrom the fly-wheel shaft.. In consequence of the knivesbeing placed on a spindle, instead of being thrown roundwithin the area of the fly-wheel, they are reduced in size,and less power is required to work them. The fly-wheelis also situated alongside of the trough, and a case is fittedover the knives and gearwork.
Turnip-cutter, formed of a cylindrical barrel, on whichthe large knives for slicing are placed in a diagonal posi-tion. The small knives for cutting strips (which are alsodiagonal) are fixed upon moveable segments, and attachedto the barrel directly under the large knives.
94 Law, E., Shettleston, Glasgow —Inventor.
A farm cart, iron plough, and model turn-wrist plough.
96 Crowlf.y & Sons, Newport Pagnell, Pucks —Inventors and Manufacturers.
One-horse cart, with new tipping apparatus. Hames.One-horse universal hoe.
98 Brodie, William, Airdrie, Scotland .
A registered drain-tile and pipe-machine. This machineis driven by steam or horse-power, and when wrought ata speed by which two women take away the pipes, makesfrom 10,000 to 12,000 two-inch pipes per day. By puttingthe rope which is attached to the driving-power on asmaller pulley, to bring up the speed, the produce is from12,000 to 18,000 pipes in ten hours. Various sizes oftiles and pipes, for leading drains, can also be made whenrequired. By putting on a set of grating dies, thismachine is capable of cleaning the stones from clay, afterpassing through a pug-mill, sufficient to make from 16,000to 20,000 two-inch pipes per day.
99 Clark, John, Eirhton Blantyre, by Hamilton,
Scotland —Manufacturer.
100 Istance, R., Carmarthen —Inventor.Beehive ventilator.
101 Epps, William James, Maidstone —Inventor.
Machine for throwing flour of sulphur upon horticulturaland agricultural crops, for the purpose of destroying themould or mildew.
The hopper contains the sulphur, and at the bottom isplaced a box containing a sieve; through the box is aspindle, attached to a spring and lever outside the hopper,and the whole is fixed before a fan-blower: the brasswheel (which moves the latter) catches the lever attachedto the box in the hopper, and causes an oscillating andtapping motion, which sifts the sulphur into the air-chamber of the blower; whence it is blown in one con-tinued cloud with great force.
103 Briggs, T., Henley Pottery, Derbyshire —
Manufacturer.
Improved beehive.
104 Ponton, George, Grangefoot, Linlithgow , Scotland
—Manufacturer.
Improved two-horse swing-plough, for lea and generalpurposes.
Two-horse plough, for forming drills; reduced indraught, and adapted for any soil.
New one-row bean-sowing machine, which can bethrown out of gear at the turnings, to save labour.
All invented, or improved and made by the exhibitor.
105 Thompson, George, 18 Great George Street,Westminster —Inventor.
Patent machine for digging and turning over earth,which may also be used as a cultivator or scarifier, bysubstituting one or more hoes or coulters in place of eachspade.
Working model of part of another digging-machine, ofa lighter construction; to be worked in a similar manner,but having only one row of spades; for use on light soils,and adapted for forming broad or narrow ridges.
106 Halstead, Charles, & Sons, Chichester —Inventors and Manufacturers.
Improved iron ploughs, either for light or heavy soils.Improved oil-cake breaker, made entirely of iron.
107 Sewell & Co., Longtovm, Cumberland, and 30 Speak!
Street, Hyde Park —Manufacturers.
Netherby plough, designed to cut, displace, and leavein a proper position furrows of various widths and depthson moderately stiff soils, where the more “ springy ’action of a lighter plough increases the traction, anddeteriorates the appearance of the work done.
It is sufficiently strong for almost any soil, but for verystiff clays it requires another form of mould-plate.
The principal resistances in ploughing are, the quiescenttenacity of the soil, and its rubbing- friction along themould-plate. The first is the most important; for sincethe friction of a body at rest is much greater than i tsmoving friction, it follows that, in a well-formed mould-plate, the rubbing friction of the soil can only be limited-To start, displace, and replace the soil with least power,are, therefore, the requisites of a good plough.
These qualities obtained, a few pounds more or lessweight in the implement itself could make no materia*difference; as the actual weight should depend upon thenature of the soil to be removed. The attachment of thetractive power, however, is of importance; since it shouldbe in or as near to the direct line of the greatest resist-ance as is practicable. The greatest resistance will bebetween the cutting edge of the coulter and that of theshare, which fairly starts the soil into motion, as is testifi®.by the greater wear of these parts. Since this point lSnear the land side, it is evident that horses walking in th®previously displaced furrow are pulling at an angle ®several inches from the land, requiring some compensatingresistance to keep the plough to the land.
When one horse, however, is attached on each sw®>and as near to the line of resistance as they can be, the)*angular traction balances each other, and results in the*combined force forming a diagonal line of traction in t*>direct line of resistance, requiring less power and l cSguidance to produce straight uniform furrows. , e
The Netherby plough seeks to lessen resistance by **'anti-frictional curvature of the mould-plate, allowing tndisplaced soil to press with less intensity over a lal \_surface, thereby preventing abrasion; and by the attaC aSment of one horse on each side of the line of resistance, ‘sufficient power for all ordinary surface work.

Patent liquid manure-distributing cart. Thedistributed by means of revolving troughs, which tit on two sloping boards .or aprons, whence it falls t peland in a thick or thin sheet, as may be required > gcistern may also be turned up to empty itself, by tua handle.
Patent liquid manure drop-drill: it works on the ^principle as the preceding, by means of a successismall buckets, which throws the liquid into tube®’which the seed is conveyed from a seed-box. It d* 1seed and liquid, either at intervals or continuous, asbe required.
