Definitions
- Figure 1 is the furrow side of the moldboard, with the shareplaced thereon, and forms a regular twist from point to heel, so that when the earth has been by the edge of the share cut it will regularly rise and cast over, with the fresh earth uppermost, and this twist is confined between the lower edge of the moldboard and the line B.
- O is a cuttingedge
- This colter has a convex curve on the land side, which terminates in a sharp edge, that is called the cutter, at D.
- the edge D is to be nearly upon a straight line from 3 to 4, allowing a slight regular rise or curve between these points, and from 4' to the top at the beam to rise in a quick concave curve, continuing and preserving the edge to the beam-plate, which supports the beam.
- Fig. 2 represents the landside of the moldboard, or, as may be termed, the back or inside.
- E is the beam-plate, and as made belongs to the beforedescribed casting, and is of the width on top to correspond with the thickness of the beam, so as to give a sufficient bearing and a requisite strength;
- F the screwbolt that passes through the cap E and the plow-beam, so as to connect the beam to the mold-board, the bolt to be put in from the under side, and the lightening-bar on the beam
- C is a rib or bar cast to the back of the moldboard and connects with the cap E, and is brought flush to the edge and extends down 7 near to the lower edge of the mold-board,
- Fig. 3 is an end view of the landside. This may be taken off and replaced with another when worn out.
- the landside is raised from the sole perpendicular to the line 6, and that line to 7. There is a regular curvature to prevent the dirt from falling over in the plow.
- S is the sole, which is aflange on the bottom of the landside; 9, a hole to receive a screw bolt with a countersunk head, which connects the beam-handle to the landside.
- Fig. 4 gives an inside view of thelandside. 10 is a small projection upon which the end of the beam-handlerests; 11, a flange or bar made in casting to strengthen.
- Fig. 5 exhibits a view of the mold-board without the share.
- K is a recess sunk sufficiently to receive the share, that laps upon the mold-board so as to form an even surface on the face.
- 12 12 are grooves. 13is a conntersunk hole.
- Fig. 6 is the lower side view of the share L.
- 14 14 are bars which titinto thegrooves 12 and 12.
- 15 is a projection that tits in 13.
- L is a a top view of the share and so much of the cutter from 3 to 17.
- 1G is a bolt-hole, which receives a screw-bolt with a countersunk head, and passing through share and mold-board with the nut below that fastens the share to the mold-board.
- Fig. 7 represents a share with a. common s .vord or cutter connected with the share, the share in other respects to be made as the one already described, which may be made use of on those plows.
- Fig.8 exhibits a perspective View of the plow.
- the handles and beam are connected together in the usual and common way.
- the clevis, 850., are also made and placed on the beam as others.
- the plow is intended for the usual agricultural purposes, &c.
