Letters Patent No. 111,056, dated January 17, 1871.

IMPROVEMENT IN PLOWS'.

The Schedule referred to in these Letters Patent and making parool the same- To all irliom, `it may concern:

15e it known that Ii Tnoiuas HAninXG, of La Fayette, in the county of Tippecanoe and State of Indiana, have invented a new and useful Improvement in Walking-Flows; and I do hereby declare the following' to be a t'nll, clear, and exact description ot' the same, reference heilig had to the accompanying draw ing, in wliieh- Figure l is a plan View of my invention.

Figure 2 is a longitudinal vertical section of the same,

lvf-jlll'CS 3 und t exhibit the inode of securing the desired inclination of the standards.

lt is well known that, to secure the inost satisfactory action, it is required that the height ot" the` point of draft shall be adjushile` to adapt the niaehine for large or small horses, and also to decrease as much as possible the strains upon the frame when the point of dralt is far removed above the axis ot' the bearing-wheels.

My invention, therefore, consistsin the method of adjusting the heightot` the point of draft by inclining the crank-shaped axle ibrward, and adjusting the angle ofthe tongue thereto, as may be required.

1t further co11sists,'also, in the method ot` const-ruction shown in the axle, and in the attachment of the drag-bars or plow-beams thereto; in the method ot' attaching and supporting the plow-beams.

That others may fully understand my invention, I will particularly dscriheit. Y

A is `the tongue, to which the team is attached in the ordinary manner, by double-trees, .&c., the lininnier-strap indicating the point ot' attachment.

B is tho axle, made in thc form of a double crank, and having the wheels attached at its ends.

The mode ot' construction which I prefer is shown in the drawing. I make cach end ofthe axle oia cast iron plate, i), forming it with linclosing-langes, e, at its upper end, to receive the end of the wooden inn- 'which i'orms thc cross-piece ofthe axle, and with seveiatsoekets, d, to reeeircihe wrought-iron or steel pills c f, upon which the wheels turn and the plowhezuns nre attached.`

rlhe axle is in this way constructed with great strength in proportion to the amount of inaterialem- Iployed, and the several sockets d (l permit an adjustment of the pins up or down.

The axle B is made cylindrical at its central part, as shown in the sect-ion iig. 2, andthe tongue A is attached to the' axle by means oi' a strap, D, or other equivalent means, to form a joint at that point capable of'permitiiug a relativeinotion of tongue and axle.

lt will appear evident that the height of the tongue abovcthe ground may be raised at pleasure by permitting the axle B to incline, more or less forward, as, when the parts B are upright, the tongue would be at its greatest elevation, and adapted to cultivate corn of considerable height; and, when the axle-piece L should he inclined forward so as to be horizontal, the tongue would be quite nearthe ground, and the Vdraftstrain would be direct upon the plow-beams. This latter is an extreme adjustment, and will be seldom or never needed.

The desired relative positions 0f tongue and axle may bc preserved by means of braces E E', or other convenient means, an'dfif said braces are employed, they may be adjusted by means of holes g g i'n the tongue.

The braces E are attachedto the cast-pieces b, by means. of the \vheel-spinilie"e,' and therefore a part ot' the draft-strain is broughtalmost direotlyto the wheelaxle pins ce.

The pins f are extended toward the middle of the axle far enough to receive the draw-plates F, andthe i'nner ends are supported by the brackets G and braces The plates F are employed so that the draft-point ot' the plow-beams H can be shifted to or from the center of thc axle to make the plowsrun more or less near to the row of plants. Several holes, 7L, are

therefore made inl the plate F at the forward end of the plow-beams H. A T-head plate, it, is secured, and the coupling-bolt t passes through said T-head and through the plate F, and attaches the plow-beam to the axle;

It will be observed that the plates F are capable of motion in a vertical direction upon the bolts fas eenters, and that the plowbeams H are capable of horizontal motion upon the bolts i, as centers, while the lateral extensions of the T-heads will prevent any undue rocking motion oi' the plows.

The plow-standards J are secured to the sides of the plow-beanis H by means of bolts q, which pass through both beam and standard, and each standard is set off at the proper distance bythe block m which is interposed. These blocks are made so as to present a long foot in contact with the beam, as shownin figs.

1 and 3. No string-brace will then be required to support the outside ofthe standard. 1 It is desirable to give the shovels a lateral adjustment, so that they may be set a little further out or" in somt-imes, as may be desired, and the washer r, thicker upon one edge than at the other, isinterposed between the block m and the standard, and, by shifting the position of the lthin edge of said washer, the desired inclination may be; given to the standard.

5'. The braces Kv pass through the center of the standards J near their lower ends, and thus secure a central draftfor the shovels. The front ends of said braces are bolted to the plowlbeam in the usual way.

The plow-handles M are set off toward the walking side, as is usual, to enable lthe driver to walk at one side of the row of plants, and manage both plows.

conveniently.

When the apparatus is to be transported from place -to place, it is necessary to elevate the plows and mainthe plows, as shown in dotted lines in fig. 2.

Having deseribednxy invention, What I claim as new is- 1. The axle B, constructed withthe Cast-iron cud pieces b l), when Said end pieces are provided with sockets d d and flanges c c, for the purposes described, and the wooden cross-bar, as set forth. l

2. In a straddle-row cultivator, the draft-pole A and a. double crank-axle B, when jointed together substantially as described, so that said draft pole and axle can be adjusted iu height, for the purpose set forth.

`3. The combination of the double-crank axle B, tongue A, jointed thereto by means of the strap D, and the braces E, for the purpose of adjustment, as set forth.
