Imm Patent No. 39,801, dated May 4,1869.,`

IMPROVEMENT- IN cULTIvA-rons.

The Schedule referred toin Be it known that I, PHILANDER SBRAGU, of Pecatonica, inthe county of Winnebago, and` in the State -of Illinois, have invented certain new and useful Improvements in Oultivators and do'hereby declare that 1 the following is avfull, clear, and exact description thereof, reference being had to the accompanying drawings, and tothe letters of reference marked thereon.

The nature of my'invention consists in the construction `and general arrangement of'a cultivator, which will hereinafter be fully "set forth.

In order to enable others skilled in thear-t to which myinventon appertains, tornake `and use the.same,1

will now proceed to describe itsconstruction and operation, referring to. -the annexed drawings, which form a part of this specification, andfin which- Figure 1 is a plan view;y Y

Figure 2, a sectional side view; f f Figure 3, a plany view of the harrow, to be attached to the cultivator;` v 'A Figure 4, a front view of the plowshares; and

Figure 5, side yiewof a brace used `in the cultivator.v A A represent two beams, placed at suitable distance rapart at the rear end, and joined together at the front, end, forming the tongue to which the team is attached.

On the outer side of each of the beams. yA A, is secured a bent rod, B, which forms theaxle for the wheel O.

The tongue being forked in this manner, and running rear of the `front ends of G G, on the beams 'A A, and bent bars HH,` assed through the said eye-bolts, and. secured to the cams F F, by pins, as seen v in fig. 2.

Near the rear ends 'of the beams F F, plow-shins I `I are secured, and they are further braced, as seen in iig. 2

` In .front of the shins 1 I, on `the beams F F, are piv- ,oted theI shins KK, the( upper ends o f whicheXtend above th' y' plow-beams, Vandliorm handles within reach of the drivers feet.- i 4 These shins are braced to the beams F F, byhinged bracesL L.: B'y this means the shovels can be moved forward', and cleared from the ground when desired. n y Near the rear endofthe beams F .F is an adjustable `cross-bai", M, to which is secured' afshin, N, so as to allow a's'hovel in the centre, between the side-shovels.

. The shovels O` O are ofthe peculiar shape shown in thes'a Letters Patent and-making part of the sme.

fig. 4,suitable both for cultivating and lcorn-planting,

thus saving considerable expense;

To the plow-beams F F are secured handles P P,

`which extend upward, and passth'rough rings or eyes on the rear side of a cross-bar, R, which is supported `on the standards S S, said standards-being secured to the beams AA. By this arrangement, it will be seen it is impossible for the plow-beams F F to tip over, but always remain with the plows downward.

The distance between the plow-beams F `F is regulated by means of an adjustable brace, T. This brace is constructed, as shown in g.5,with loops, which are placed around the handles P P. They are then bent,

and meet inv the centre, where theyare :fastened to-V getherby a wire, Y, which is suspended from the crossbarR. It will be seen that, by contracting or extending the two parts of the brace T,- the plow-beams F F are brought closertogetlier, or further apart, as may be desired. -V

The plow-beams F F are raised or lowered at will,

by means `of cords al a, which are secured to the same;

then passaround pulleysb b, on theunder side of the cross-beam R, and the other ends secured to two'levers, W W. n i

These levers are pivoted at ltheir forwardends, in'Y front of the standards S S, to earsrY Y, on'the beams A A, 'and extendtoward the rear, so as to bewithin reach 'of the driver on his seat-E.

On the inner side of the standards S S are two segmental'rack-bars, Z Z, and on the levers W W are pawls, or dogs `c c, which catch on the notches on saidl rack- Vbars, and thus hold the levers, and, through thecords a a, also the. plow-beams, at any desired height.

'lhesepawls or dogs are moved out ofthe said notchesy by means of a small lever, d, pivoted near the rear end of the lever W, said small lever d being 'connected'by a rod, e, to the'pawl c.

By pressing down the lever d, the` pawl is moved out ofthe notches and as soon as the pressure is removed from the lever'd, a small spring underneath throwsthesame up again, and consequently also the pawl c into the notches on the rack-bar Z.Av l

' On the inner side of he .beams A A, at the point where the ears Y Y are placed, is a semicircularbrace,v f, which is so arranged that the ears Y Y may act as braces lto it, so as to prevent it from moving either ,for- Ward or backward.

To the centre of the brace f is a bent rod, g., pivoted,

which rodor bar follows the curve of the brace underneath, and extends below the beams A A, then is bent outward, and thenffo'rward, at its forward ends formi ing the hooks h h, to which the doubleY and single-trees will be attached.' v v By removing the cross-piece M, with the fifth shovel attached'I can easily attach the harrow X, fig. 3, and,

if desired, I can easily remove the whole plow-arrangement, by removing the plow-beamsF F, andsubstitute the han'ow, which will make it what is commonly called a sulky-harrow.

Having thils fully described my invention,

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

l. The arrangement of the forked tongue A, axles B B, wheels C O, semieiroular braces Dand f, seat E, and bent rod, or bar g, with its hooks h h, substantially as herein set forth. A

2. The arrangement of the forked tongue A, plowbeams F F, handles P P, and adjustable brace T, all
