Letters Patent No. 84,449, dated November 24, 1868.

IMPROVEMENT IN CULTIVATORS.

The Schedule referred to in these Letters Patent and making part of the same.

* -o-QH To all whom lit lmay concern:

Be it known that I, SETH WAY, of La Porte, in the county of La Porte, and State of Indiana, have invented anew and .useful Improvement in Cultivators; and I do hereby declare that tle following is a full, clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, in whichgigure 1 is a plan view of my improved cultivator, an

Figure 2 is a side elevation of the same.

Corresponding letters refer to corresponding partsin both figures.

The object of this invention is an improvement in cultivators 5 and It consists, rst, in a swivelling joint attached to the tongue of the carriage, and to which the forward end of the'plow-beams is attached; and

It ftuther consists in a peculiarly-thrilled lever, for raising and lowering the plows and their beams; and

It fmther consists in a stirrup which passes over and embraces the double plow-beams, and by which their position with reference to each other is regulated and Lastly, it consists in a device, by which the tongue is secured to the axle.

A is the tongue of the carriage, to whichthe forward ends of the plow-beams are secured, by means of the swivel-joint hereafter to be described.

B B are the wheels, which are of the usualconstruction.

O isthe double-tree, which is of peculiar construction, it being composed of two barsor parts, of equal length and width, running parallel with each other, but

having a washer between them, in their centres, of sufiicientvrthickness to insure their being kept a distance apart suliicient to allow the inner ends of the singletrees to pass between them, by which arrangement l am enabled to provide for attaching four horses, should it become necessary.

D D are the levers of the plows, which consist of two bars ofwood, of sulhcient length, width, and thickness, the two being jointed together, at their front ends, by a bolt, which passes through them and through the lower end of the rod or bar, which forms a portion of the swivel-joint above referred to. From this point, cachot" these beams, or such portion of what may be termed a double beam, diverges from the other at an angle sufiicient to give the required distance between the plowswhich are placed thereon.

E E are the handles of the plows, which are of the usual construction, and are secured to the beams in the usual manner.

F F- are the standards, the upper ends of which are bolted or otherwise secured to the plow-beams, and to the lower ends of which the shovels are secured. In addition to the above, these standards are provided with .a brace, (i, the lower end of which is provided with a series of holes for the reception of a bolt, which passes through said brace and through the standard, by which means the angle of such standardhas well as the depth tewhich the plow enters the earth, can be regulated, the'upper ends of such braces being secured to the beams of the plow.

1 is a lever, for raising the plows and their beams clear of the ground, when it becomes desirable to do so.

This lever' is of peculiar construction, it consisting of two portions, which are nearly at a right angle -to each other, and yet varying om such an angle, as Will now be described.

The long arm of this lever is of suitable length to enable the driver to raise and lower the plows with ease, and is secured to the tongue, at the proper point, by means of a bolt, upon which it turns, and which forms its fulcrum. From one side of this lever, and at a point opposite such fulcrum, extends an arm, at such an angle that when the long arm assumes a horizontal position, which, as shown in lig. 2, is when the plows are in their working position, the short arm will stand slightly back of a line drawn through its centre of rotation, the object of this arrangement being, that when the long arm of the lever is thrown back upon the axle, for the purpose of raising the plows, aportion of their weight shall be caused to rest upon said long arm of the lever, to prevent its being displaced while the ma chine is being transported from place 'to place.

2 is a socket, which is secured to the tongue of the carriage by means of a bolt, said sockets having anches, which embrace the upper' and lower edges of said tongue. .Passing vertically through this socket, is a rod, which has a nut upon its upper end, which rests upon said socket, and carries the forward ends of the plow-beams, and as said rod turns freely within the socket, it permits of the required amountof lateral vmotion being given to the rear end lof the plow-beams.

3 3 are sockets, which are placed upon the ends of the wooden portion, 7, of` the axle, which sockets have formed upon their upper sides, and near their inner ends, additional sockets, for the reception of the ends' ofthe tongue A, which are secured therein by means of keys driven through said sockets and above the tongue.

In order that the metallic and Wooden portions of the axle and tongue may be iirmly secured together, the socket which receives the axle, has a portion of its upper surface cut away, where the tongue passes through or across it, bywhich means, as the tongue is passed through its socket, it 'enters a recess in the top of said axle, and as the key is driven home, the three parts are bound rmly-together.

4 4 are clamps of metal, which embrace the two s ections of each of the plow-beams in the rear ofthe handles, and as these portions of the beams are constantly diver-ging from each other, it follows, that, as these clamps are pressed or driven backward, the diverging ends are brought nearer to each other, by which means the distance between the plows or shovels, which are attached to said sections of the beams, is regulated.

5 is the hanger, which extends from the'elevatinglever l to the plow-beams.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent is- 1. The swivelling joint 2 8, secured to the tongue of the carriage, substantially as and for the purpose described.

2. The construction of the lever l, and its combination Withthe plow-beams, substantially as shown and described.

3. The arrangement ofthe stirrups 4, with reference to the tWo diverging portions of the plow-beams; substantially as and for the purpose described. i

4. The socket 3, and its combination with the axle 7 and tongue A, substantially as shown and described. In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

Witnesses:

'ROBERT A. Hnws, JAMES A. Hnws.
