IMPROVEMENT I/N ROAD- SCRAPER The Schedule referred to, in these Letters Patent and making part of the same.y

To all whom it may concern.'

chine, fi. e., the mold-board, and its exteusion,7 the' land-side and its extensionj 85e.;

My invention consists in thecombination and arrangement of the devices, as will be hereinafter explained. f

To be more particular- A represents the mold-board;

B, the beam;

C, the extension f the mold-board, made in two pieces, O D.

' The forward end is attached to and slides with an eye, t, on an iron rod, fu, fig. 3, riveted to the inside surface of the mold-board proper, A; the latter overlapping the face of the extensionv i The height of the latter may be less than that of the mold-board proper, made of wood plank, and faced with iron plate; the lower edge of the platel extending below vthe wood, andA slightly bent outward.

D, the tail of the extension mold-board, of similar shape and size, hinged to a plate, fw, behind the planks, and which plate covers the joint, forming a bearing for the play of the taiL Y A pin or bolt, near the center of thc joint, is the pivot k.

y Both the planks and the iron facing are made with a semicircular joining, embracing the whole width of the fiat part of the mold-board extension, but the facing is bent backward, at a bevel beneath the joint at q, to allow the tail to pass this angle behind that of the forerunning extension C, when the tail, or rather its rear extremity, falls below the level of the piece C.

This tail D can be thrown np put of operation by means of the hinge and guide d.

E, the extension of the land-sides, also of wood plank, iron faced, hinged or pivotcd at its forward end c near the junction of the land-sides proper, G, with the.brace 7L, or rather, the pair of braces h h, which terminate above at the rear end of the plow-beam B.

F, a lever, supported on the top of a. brace, f, ris-A ing vertically lfrom the extension of landsides near the plow-handle a, the handle of the lever ex tending to the hand of the operator near plow-handle a, the forward end of the same running forward over the plow-beam and mold-board, connected with the former by a link, y. A

G, land-sides of plow proper.

a a, the handles of the machine, set almost as in an ordinary plow, and bolted to the wood-work ofthe extension on each side of the machinev near theV middle of D, and on forward part of the extension oi'- the land-sides E.

b, the rod, c n which the eye yr of the guide e slides, the latter being securedto the extension of the landsides E, and extending toward and running parallel with the rod l), and pierced with several holes, to jadmit the bent end of the rod l), when the angle of' the extension of mold-board has been adjusted.

d, guide, fastened to the end of tail D, and curw ing upward and passing through a slot or eye, m, on the handle of machine a, by means of which tail D is retained in place or raised from the soil.

e fg he' k m a o have been described above. Y

p,{a slot, cut vertically in the end of the 'plow-.beam Y B, acting as a guide and stay for the pl0w-beam,'em bracing, as it does,- the vertical brace f, when the point of the plow A is raised from the soil, on going to or leaving theiield of operation.

The operation of this invention is as follows, to wit: In4 going tothe place of operation, the handle of the lever E is depressed, keeping, by this means, the

` point ofthe plow, as before-mentioned, from enteringthe soil, in the position indicated bythe dotted lines in iig. 5. When arrived at the Adesired place, the lever is released. `The extension D of the mold-board A must then be adjusted, by means of the adj usting-rods and slides l) c s, to the required angle, either more or less inclined to the land-sides, as may seem best for draft or for space required to be worked over. The i tail D must be thrown up out of the way, of course, 'in a narrow excavation or ditch.- But, in case of its use,

it will, by its weight, accommodate its beveled edge to the slope of the soil or the incline of a road, in road-making, thc guide d sufficiently bracing it.

Suppose the machine now moving forward, the extensionmold-board C will remain at a level, while the plow A will bury itself, more or less, in the soil, being securely connected with, but having sudicient vertical y motionby the iron rod u and eye t, (see fig. 3.) The ring or extension D O rolls or scrapes away the soil raisedby the plow A, for a spaeemany feet Wide, thus saving the labor'of many men and several scrapers to do the same Work.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1 The lever F, so arranged as to depress or elevate the landside E, as described, in combination with beam B of plowr A, substantially as set forth.

^ 2. The mold-board O, with extension D as attached thereto, curved guide ll and handle a, in combination with plow A, substantially as set forth.

3. The lever F, with landside E, having a depressing and elevating motion, and handle a, as arranged with mold-board G, provided with handle u, and having the extension D adjusted by means of the curved guide d, in combination with plow A and beam B thereof, substantially as set forth.

In testimony that I claim the foregoing I have llerennto set my hand this 30th day of Angustf1869l PERRY M. STEPHENS.
