what is called the ledger blade in the 

 common siiears, so that the cloth passes 

 between the said bed and the said 

 stationary blade. The moving blade of 

 the shears is fixed on the circumference 

 of a cylinder, situated above the said 

 fixed blade, and revolving upon an axis, 

 so that the edge of the moving blade is 

 carried against the edge of the fixed 

 blade, and cuts away all the wool of the 

 cloth whieii rises above the edge of the 

 fixed blade. Several moving blades are 

 fixed upon the same cylinder, to act in 

 succession against the fixed blade; and 

 the said moving blades are placed ob- 

 liquely to the axis of the cylinder, or in 

 such manner as to form a portion of a 

 spiral, whilst at the same time every 

 portion of the said edge bring equi-dis- 

 tant from the said axis, it is manifest 

 that in the revolution of the said cy- 

 linder, every part of the said edge will 

 be brought in succession into contact 

 with the fixed blade, thus cropping otl' 

 in its revolution all the wool, wliich, by 

 the progression of the cloth over its bed, 

 is brought against the fixed edge. By 

 the time that the revolving edge has been 

 in contact with the whole length of the 

 fixed edge, and is ready to quit the lat- 

 ter, sooner or later, according to the 

 number of edges revolving with the cy- 

 linder, the revolving edge next in suc- 

 cession is brought into action; and in 

 like manner the rest in succession are 

 brought into action, and the whole con- 

 tinued are in action as long as may be 

 wanted. The cloth is stretched in width 

 by what Air. Piice calls stretching bands, 

 and the Ijcd or supjjort on which the 

 tloth is cut can be adapted in length to 

 the breadth of the piece of cloth between 

 the lists or forrels, so that the cloth only 

 will be supported or borne up to the edge 

 of the fixed blade, whilst the lists, being 

 depressed below the level of the bed by 

 guards, will escape the action of crop- 

 ping 



'I'he particulars which Mr. Price 

 claims an exclusive right to use in ma- 

 chines for shearing cloth are — First, in 

 the method of consiruction employed in 

 making the bed or suj»port on which the 

 cloth is shorn, so as to be adjustible to 

 different breadths by means of sinking 

 pieces, and sliding pieces under tiieni, 

 at the ends of the said bed or support. — 

 Second, the whole contrivance and con- 

 itnielion of the -.itretehing bands and 

 feeding talde. — Third, so connecting the 

 Eppaiatus of the .stretching bands and 

 ti;eding tabic with the movements of th«

sinking pieces, that flic action ofbotli 

 may be coincident, as above described. 

 — Fourth, in a row of pieces of metal 

 acting as springs, which press the cloth 

 gently down upon the bed before it ar- 

 rives at the fixed blade to be shorn, by 

 which he is enabled to bring i!ie cloth 

 with safety nearer to a level widi the up- 

 per surface of the fixed blade, so as to 

 shear it closer than could otherwise bo 

 done without eudaugeiing the cloth. — ■ 

 Fifth, in the arrangements of the parts 

 of the machine, as described and as 

 shewn in the drawings, and in the means 

 for adjusting the dillerent parts to th^ 

 best positions for working. 



To William Plenty, of Nen-hny, 

 Berks, iron fmuifkr ; for a Plovgh, 

 OH a new and improved Construction. — 

 Dec. 22, 1815. 



The following is Mr. Plenty's specifi- 

 cation : — The beam in the first place is 

 curved, whicli gives the ploughman an 

 opportunity of seeing his furrow, and 

 enables him to work in a direct line 

 with more facility than in any plough 

 now in use. To the beam is fixed, by 

 means of screw bolts and nuts, a body 

 of cast iron, winch projects over the 

 land side, being tilted to the curved 

 beam, and is cast so as to form at top 

 two plates, one of whicli goes under- 

 neath the beam through which the screw- 

 bolts pass to fix it to the beam, and the 

 other on the furrow side or face of the 

 beam. The bottom part of the cast- 

 iron body, where tlie share is fitted on, 

 is cast witii a hollow ; the convex side 

 fills up the interstice between the body 

 of the mould plate, the concave or open- 

 ing being' on the land side of the body, 

 and which, when the shoe is screwed on, 

 form a box, within which are the nuts 

 and screws M'hieh fasten the mould plato 

 and share to the body, protected from 

 all friction in the action of ploughing. 

 The mould [ilate is of cast iron, curved, 

 and fastened to the body by means of 

 screw bolts and nuts, wliieh come within 

 the box above described. The share is 

 also lixed to the body by means of a 

 curved screw bolt and nut, protected 

 within the same box. 'I'he share has 

 also a wing, ia an lioiizoiital position, 

 wliich serves as a cutter in ploughing. 

 In the space between the body and 

 mould plate is a friction wheel of cast 

 iron, one end of the axle ol' u liieh is fix- 

 ed in a grooved wrought iron arm ; 

 which grooved arm fits in aiiotlicr 

 iiousii uu the land side of tli« body, and
