Twelfth,-the mode in which the types are forced down in the line, after they are brought to the receiver by the endless belt; whether it be effected by means of the small endless chain or belt n, n, in conjunction with the pulley m, round which the chain passes, as seen in fig. 13, or by means of a snail cam, (as shewn in fig. 20,) or other excentric; and whether the said cam or excentric acts itself directly on the type, or through the medium of a lever or pusher.
Thirteenth,—the manner in which the line of types is lowered from the receiver into the galley.
Fourteenth,—the manner in which the galley is mounted in the machine, as shewn in fig. 19.-[Inrolled in the Petty Bag Office, September, 1842.]
Specification drawn by Messrs. Newton and Son.
To Charles Callis Baron WESTERN, of Rivenhall, in
the county of Essex, for an improvement in drills, for the purpose of drilling corn, grain, seeds, pulse, and manure. -Sealed 3rd November, 1838.]
This invention relates to those drilling machines which are commonly known by the name of the “Suffolk lever drill," and consists, firstly, in the application of an improved foreaxle and wheels, combined with apparatus for guiding the machine. On the periphery of each of the fore-wheels a “ feather edge” or rib, in the middle, is formed, to divide the clods of earth which might impede the progress of the machine; and the axle, to which they are attached, is arched or curved: it turns readily upon a centre pin, beneath the front frame of the drill, and near its left end an upright standard is fixed. The upright part of the standard is connected to the lower end of an inclined rod, which has a screw formed upon it, near its upper end; this screw works in a nut, secured to the foot-board of the seat on which the man sits who guides the machine, and the rod terminates in a handle or handles. The machine is guided, in the desired direction, by turning the rod, and thus mov
ing the left-hand end of the fore-axle towards or away from the front part of the machine.
The second part of the invention consists in connecting the levers of the drill (which carry the coulters and coulterpipes) with their axis, by means of the improved hinge, represented in Plate XVIII. Fig. 1, is a front view, and fig. 2, a section of the hinge. a, is part of one of the levers, attached to the hinge by the bolts b, b, passed through the openings c, c, and secured by nuts d, d. The hinges turn on the axis e, and the outer ends of the levers are suspended by chains, as usual; so that if the coulters meet with a large stone, or any similar substance, the levers will rise, and allow them to pass over it. Any lateral movement of the levers is prevented, by the insertion of fillingpieces f, fig. 3, into the spaces between the barrels g, of the hinges; the barrels being made sufficiently long to keep the levers perfectly parallel to each other, and in a line with the course of the machine.
An improvement in the method of fastening the coulters to the levers is also described in the specification; it consists in applying metal sockets to the levers, and securing the coulters therein by means of wedges. Fig. 4, is a plan view, and fig. 5, a longitudinal section of part of a lever, furnished with one of these sockets. h, is the socket, which is attached to the lever a, by the bolts i, i, and nuts j, j; and k, is part of the coulter, fixed in the socket by the wedges, l, l.
The patentee claims, Firstly,—the addition to a drilling machine of a fore-axle and pair of fore-wheels, of a peculiar construction, and of an apparatus for guiding and directing the course of the machine, so as to counteract the unequal draught of the horses, and keep the machine in its proper course, in order that the rows of corn shall be perfectly straight and parallel to each other; and, hy which means, in many cases, the horse-hoe may be safely used, and, in all cases, the hand-hoe may be used more readily and effectually than heretofore. Secondly,—the application of the improved metallic joints or hinges to the levers, by which they are kept perfectly parallel to each other, and
in a line with the course of the machine. Thirdly,-the application of metal sockets to the levers, by which the share or coulters are fastened thereto, in lieu of the more tices formerly made in the levers.—[Inrolled in the Inrolment Office, May, 1839.]
TO ALEXANDER Mac Rae, of the London Coffee-house,
Ludgate-hill, for improvements in machinery for ploughing, harrowing, and other agricultural purposes, to be worked by steam or other power. - [Sealed 24th De- . cember, 1839.)
The improved agricultural machinery, above referred to, is intended to be used in the colony of British Guiana, where the cultivated land is flat, or nearly so, and the fields are separated by navigable canals, which run parallel to each other, at a distance of from 240 to 360 feet apart.
The machinery consists of a steam-engine and drum, contained in a punt or other vessel on the canal, at one side of the field, and of a large pulley, contained in a punt on the canal at the other side of the field. The ploughs or other implements are secured to a carriage, mounted on four large wheels, and to this carriage one end of a rope or chain is attached, which passes twice or three times round the drum and then proceeds beneath the carriage to the pulley in the other punt, and, after passing round it, returns to the carriage, and is secured. When the drum is caused to revolve, by the power of the engine, it draws the carriage and implements across the field; and on the motion being reversed, the carriage returns to the other side of the same. This operation is repeated over the whole of the field; the punts and carriage being moved a short distance onward, each time that the motion is reversed.-- [Inrolled in the Inrolment Office, June, 1840.]

TO William HensMAN, of Woburn, in the county of Bed-. ford, machinist, for improvements in ploughs.—[Sealed 30th December, 1840.]
These improvements consist in securing the coulter to the plough-beam, in such a manner that its point may be readily moved to or from the land-side of the furrow, whilst at the same time the distance of the coulter from the end of the beam may be easily adjusted.
One of the modes of fastening the coulter is represented at figs. 1 and 2, in Plate XVIII.; fig. 1, being a side view, and fig. 2, a transverse section of part of a plough-beam. The beam a, is partly embraced by a plate or clamp b, through which the ends of two eye-bolts C, c, pass, and are secured by two nuts d, d; these eye-bolts hold the coulter e, firmly against the projection f, on the beam a; and hence, by screwing one eye-bolt tighter than the other, the point of the coulter will be moved to or from the land-side of the furrow. By making the projection f, sufficiently long, the coulter may be set at any required distance from the end of the plough-beam a.
Another method of attaching the coulter is shewn at fig. 3. g, is a plate, on which the projection f, is formed, for giving the side motion to the coulter, instead of its being on the beam a, as shewn at figs. 1, and 2; against this projection the coulter is held by the eye-bolts c, c, and the lower bolt, passing through the plough-beam, serves as an axis to the plate g. To the front end of the plate a screw h, is attached, by a pin-joint, and after passing through the projection i, on the side of the beam a, receives a nut j; by turning which, the end of the plate g, is elevated or depressed, and the coulter is thus adjusted to any required degree of inclination or depth of cut.
The patentee claims, Firstly,--the mode of adjusting the coulters of ploughs, by the combined means of a projection f, and screws c, c, as described. Secondly,—the mode of adjusting the coulters, by means of a plate g, and adjusting and holding-screws c, c, and h, in combination with the other parts, above described.—[Inrolled in the Inrolment Office, June, 1841.]

To William Newton, of the Office for Patents, 66, Chan
cery-lane, in the county of Middlesex, civil engineer, for an invention of improved machinery for cleaning wheat and other grain or seeds from smut or other injurious matters,—being a communication.—[Sealed 11th January, 1841.]
This improved machinery, for cleaning wheat and other grain or seeds from smut or other injurious matters, consists of an external cylindrical chamber, within which a peculiar form of fan or beater is made to revolve, for the purpose of agitating the corn, grain, or seed, as it passes through the machine, and also producing a very rapid current of air, by which the smut or other impurities are effectually removed.
The body of the machine is of a cylindrical form, standing in a vertical position upon suitable legs. It consists of an outer cylinder, which is stationary, and within it a second cylinder, constituting a fan, is made to revolve rapidly. Into the space between these two cylinders the grain to be cleaned is fed through a suitable tube, formed for that purpose, and which enters through the side of the outer cylinder, near the upper end. As the grain descends towards the lower part of the machine, it is forcibly beaten by a number of strips or beaters, of metal, fixed round the periphery of the inner cylinder, which is put into very rapid rotary action, thereby forcibly beating the smut-balls, whitecaps, and other deleterious substances, of a texture softer than the grain. The rapid rotation of the inner cylinder also produces a strong current of air between the two cylinders, which carries off, through openings in the upper part of the machine, all such light matters as have been separated from the grain; whilst the grain itself, by its superior weight, gradually descends, and passes out through an opening in the bottom of the apparatus.
In Plate XIX., fig. 1, is a vertical section of the machine, taken through its axis; fig. 2, is a section of a part of the outer or stationary cylinder, shewing the arrangement of
