the rakes y, and pressed down by the roller %, which follows them.

The coulters, rakes, and roller, are all attached to a frame i, composed of two semicircular sides, connected together by bars, and fastened to the shafts 2, by suitable bolts. Motion is communicated to the shafts 9, 9, by the wheel g, and pinion 3, taking into the wheels 4, 4, on the ends of those shafts.

The delivery of the seed and dust can be stopped, when requisite, by turning the funnels u, partly round, so as to move the projecting portions of their upper ends out of the range of the cup-wheels, and thus prevent them from receiving the seed and dust, which will fall back again into the cells.

The patentee claims the machine or apparatus, herein described, consisting of parts (such as the frame-work) which are common to it under all circumstances, and of others which are in duplicate, the one or the other being made use of, according as the machinery or apparatus is employed for dispersing seed only, or dust only, or both conjointly; also the exclusive use thereof as a seed and dust disperser, and, more particularly, its application to the freeing of corn or other plants from insects.-[Inrolled in the Inrolment Office, July, 1841.]

To James HENRY Shaw, of Charlotte-street, Blackfriars

road, jeweller and watch-maker, for improvements in setting wheat and other seeds.[Sealed 19th June, 1841.]

These improvements consist in drilling or setting seed, by the aid of the machine represented in section, at fig. 1, in Plate XVIII. The machine consists of a frame a, carried by two large wheels b, and two smaller ones c; it is drawn by a horse, attached to the shafts d, and is guided by the handles e. At the front of the machine are a series of ploughs or pressers f, which form the furrows for the reception of the seed, and are connected to the frame a, by

the arms g, and wedges h. A plan of one of the ploughs is shewn in fig. 2. The seed is contained in a cylinder i, mounted upon the shaft j, and divided, transversely, into a number of compartments, corresponding to the number of ploughs employed. Around each compartment, twelve tubes k, for depositing the seed, are fixed, having each a valve 1, which is kept closed by a spring m, pressing against an arm that projects from the back of the valve.

When the machine is drawn forward, a revolving motion is given to the cylinder i, by the cog-wheel n, upon the nave of one of the large wheels b, taking into the cog-wheel o, upon the end of the shaft j ; and as each tube k, in succession, comes over the ploughs, its valve is opened, and a certain quantity of seed is discharged. This is effected by a small roller p, carried by the arm of each valve, coming in contact with the inclined end of a curved bar q, which causes the roller, with its valve-arm, to move towards the periphery of the cylinder i, and open the valve, in opposition to the action of the spring m. When the roller has passed the inclined end of the bar 9, the spring m, closes the valve again. The quantity of seed discharged from each tube is regulated by turning the screw r, and thus changing the position of a spring-plate, within the tube, so as to contract or enlarge the opening for the egress of the seed. The discharge of seed is stopped, when required, by allowing the cog-wheel o, to turn loosely upon its shaft j, (with which it is connected by means of a clutch-box) without communicating motion to that shaft, or to the cylinder i.

The patentee claims the mode of combining mechanical apparatus into a machine, by applying depositing apparatus, and parts connected therewith, to a revolving cylinder, as above described.—[Inrolled in the Inrolment Office, December, 1841.]

To Joseph WARREN, of Heybridge, in the county of Essex,

agricultural implement maker, for certain improvements in

ploughs.—[Sealed 9th May, 1842.] The first improvement consists in a method of raising or

lowering the point of the plough-share, and of regulating the height of the plough-beam.

In Plate XIX., fig. 1, represents the plough-share, and fore part of the plough-frame, with the mould-board removed, to shew the arrangement of parts for raising or lowering the share.

a, is a wedge, the smaller end of which is inserted beneath the hind end b, of the share, and to the back of it a screw c, supported by the projections d, is attached; e, is a bell-crank lever, mounted upon a centrepin f, at the lower part of the plough-frame g; the bind end of this lever rests upon the conical part of the screw, and the other end is attached to the mould-board. When the screw c, is turned, the wedge is caused to advance or recede, and, by raising the hind end of the share, to depress the point, or vice versa; the mould-board is at the same time depressed or elevated by the bell-crank lever, which is worked by the movement of the screw c.

In order that the height of the plough-beam may be regulated, the hind end of it is attached to the frame by two bolts, passed through two slots, which are made sufficiently long to admit of the beam being secured at any required height; and it is connected to the front part of the frame by a regulating screw, which passes upwards through the beam, and has a nut upon its end, to prevent the front part of the beam from rising above the desired height.

The second improvement is a modification of the first, and consists in regulating the height and inclination of the beams, and the depth of the shares and mould-boards of ploughs, by securing the beam to the top part of the frame, and connecting the latter with the handles, by means of shifting bolts, and regulating screws, as above described.

A mode of depressing the point of the share, by raising the hind end of the plough-frame, constitutes the third improvement. i, fig. 2, is the sole of the plough, connected with the frame g, by a pin-joint, at j, and having a vertical screw-bolt k, secured to it in such manner that the bolt will turn freely. The bolt k, passes through a nut l, and a bearing m; and the upper end of it is squared to receive

a handle for the purpose of turning it, and thus raising the hind end of the frame from the sole.

The fourth improvement relates to plough-shares for stony soils, and consists in making the share of the form represented in fig. 3.

The fifth improvement is shewn in figs. 4, and 5; fig. 4, being a plan view, and fig. 5, a back view of a doublebreasted plough. It consists in curving the mould-boards of double-breasted ploughs, in such manner as to present an outline continually diverging outwards from the base to the upper extremity.

The last part of this invention consists in an improved construction of drain-plough. Fig. 6, is a side view of the improved plough; it is secured to a frame n, carried by four wheels o. At the hind part of the frame is a rack p, and at the front part is another rack q, fastened to the axle of the fore-wheels; these racks are worked by two pinions r, s, mounted upon two horizontal shafts t, furnished with handles u. When both the shafts t, are turned, the plough will be raised or lowered; but when only one of them is caused to revolve, the point of the plough-share will be raised or lowered.

The patentee claims, Firstly,-raising and lowering the beams of ploughs by the combination of the parts herein described; that is to say, by means of shifting bolts, and a regulating screw. Secondly,-regulating the depth of the shares and mould-boards of ploughs by the combination of parts represented in fig. 1; that is to say, by the combination of a wedge, screw, and crank; or by the combination of the wedge with any other means of equivalent effect to the said screw and crank. Thirdly,—depressing the shares of ploughs by the movement represented in fig. 2. Fourthly,

-the mode, herein described, of regulating the height and inclination of the beams, and the depth of the shares and mould-boards of ploughs, by securing the beam to the top part of the frame, and connecting the top part of the frame with the handle, by means, in both cases, of shifting bolts, and a regulating screw. Fifthly,—the particular form of plough-share, adapted for stony soil, represented in fig. 3. Sixthly,--the making of double-breasted ploughs with mould-boards of the continually diverging form or outline, represented in figs. 4, and 5. Seventhly,—the wheel-plough, for cutting drains, represented in fig. 6, in the general combination of parts in which the same consists.- [Inrolled in the Inrolment Office, November, 1842.]

To RICHARD GARRETT, of Leiston Works, near Saxmund

ham, in the county of Suffolk, agricultural implement manufacturer, for improvements in the construction of horsehoes, scarifiers, drag-rakes, and drills, for cultivating land.—[Sealed 13th June, 1842.]

These improvements, in the construction of horse-hoes, scarifiers, drag-rakes, and drills, for cultivating land, consist in certain novel arrangements and adaptations of the working parts of those machines, the particulars of which are shewn in Plate XVIII.

As respects the horse-hoe, the first feature of the improvement is a mode of suspending the guide-bar, which supports the levers, (a series of independent arms, carrying the respective hoes,) by means of chains, passed over excentric pullies, whereby the hoes may be raised and lowered when required; secondly, a contrivance for communicating to the hoes lateral movements, by the hands of the conductor, for the purpose of guiding them in any particular course, independently of the direction pursued by the draught-horse; thirdly, a mode of extending or contracting the distance apart of the running-wheels of the machine, to suit the ridges of the land; fourthly, a method of giring different inclinations to the cutting edges of the hoes, so that they may be adapted to work in the land to the required depth, whether the ground be in a hard or soft state; and fifthly, a mode of attaching the blades of the hoes, in order that they may be readily removed and replaced, when worn.

As respects the scarifiers, intended to be employed for
