HENRY DEITOHLER, OF MINNEOLA, IOXVA.

COMBINED.CULTIVATOR AND HARROW.

SPECIFICATION forming part of Letters Patent No. 368,935, dated August 30, 1887.

Application filed June 20, 1887. Serial No. 241,912.

To all whom it may concern.-

Be it known that I, HENRY DEITOHLER, a citizen of the United States, residing at Minneola, in the county of Mills and State of Iowa, have invented a new and useful Corn Cultivator and Harrow Combined, of which the following is a specification.

My invention relates particularly to improvements in cultivators for listed corn, combined with a harrow for general work.

The objects of my invention are to accomplish in a better manner than heretofore several different kinds of farm labor with a single implement. I attain these objects by the mechanism illustrated in the accompanying drawings, in which--' Figure 1 is a perspective view of one of the sections or halves of the machine disconnected and showing but one of the fender-boards A. Fig. 2 is a perspective view of the other section or half of the machine, also detached, and showing but one of the fender boards A, but showing the section or half set or adjusted to fit the ridges between the rows of listed corn by means of the gage or clamp B B C. Fig. 3 is a view of the two sections or parts ofthe machine attached together. by means of the rod D and the gages or clamps B B 0, set so that the two parts of each section are kept rigid with reference to each other, and showing the handles E and cultivator-shovels and beams F removed,.and also showing a chain, 7, attached to hitch to for harrowing purposes. Fig. 4 is aside View of one of the fender-boards A detached, showing the slotted adjustable lugs 11 and the slotted adjustable brake or gage b. Fig. 5 is a top view of the two slotted adjustable parts of the brace G detached and disconnected, showing the slots 0. Fig. 6 is a vertical section of one of the standards or supports, B, of the section-gage B B C, and showing the bolt- Fig. 7 is a side view of the cultivator-beam F and shovel detached. Fig. 8'is a perspective of the'clamp or collar H, which attaches the beam F to the cross-bar of the gage 0, showing the plate 9 attached by nuts running on threads cut on the ends of the clamp H.

Similar letters refer to similar parts th roughout the several views.

(No model.)

My machine consists, essentially, of bars of iron or other metal, I, having the ends bent downward and (with reference to each halfsection) also bent outward to form lugs or arms J, in which I make bolt-holes h. Near the ends of said bars I, I also make bolt-holes 13. Through these I bolt to I other similar bars, K. Through the bars K, I make other holes, k, adapted to receive barrow-teeth secured therein in any convenient manner. I also attach to the bars I and-K a brace, G, composed of similar material,but consisting of two slotted parts, as shown in Fig. 5. This slotted bar G is bolted by the same bolt at t to I and K at the outer front corners and the inner back corners of the several half sections, as shown in Figs. 1 and 2.

Near the back end of the brace G, and in each part thereof, I make a narrow slot, 0, adapted to receive a bolt,Z,by means of which the two parts of the brace G can be adj nsted and fastened together, thus permitting the width of the machine to be accurately adjusted to corn-rows of varying width.

In the cross-bars K, at the front ends of the several half-sections, I insert teeth in the holes is. These teeth may be of any desired form; but I prefer common harrow-teeth, with the upper end shouldered, and a thread and nut on the end so arranged as to give the teeth a little slant backward. I also put similar teeth in the brace G for perhaps three-fourths of its length from the front end. Near the back end of G, I omit the teeth to permit the escape of any clods or lumps which may pass through the teeth of K, and which may also fail to be pulverized by being forced up the sides of the ridge, and thus prevent all possibility of the machine becoming clogged. The curved arms J, with holes h, admit of the half-sections being attached together by means of a .rod, D, with nut or key at one end and an eye at the other, or they may be attached by bolts and chine by means of the handles E, one of which is attached to each section. The handles are common wooden ones bolted to an iron plate or piece, at, so arranged as to admit of its being bolted to the bars Ithrough suitable holes made for the purpose. To the handles I also attach light iron braces L, suitably bent and provided with holes, bolted together at the upper ends through the handles and held at the lower ends by the same bolts, t, which connect the bars I and K. By varying the angles of the braces L the handles can be set in any desired position, and the inner brace L may be suitably bent and fastened at its lower end by the bolt or rod passing through the arms J. Both the handles can be thus attached to a single section when it is desired to harrow in grass-seed or grain in standing cornstalks. In the latter case the cultivatorbeams and shovels F are removed and the second handle bolted on through the beam-lug bolt-holes a.

On the bar I of the inner part of each section I attach a metal lug or arm, 0, by a bolt passing through both, adapted to be bolted to the beam at its lower end through the bolt-hole a. To this lug I attach the bent and curved metal beam F, adapted to pass over the crossbar 0 and carry ata suitable depth a common cultivator-shovel, which cuts down the apex of the ridge. The beam F is secured to the crossbar C by means of the clamp H, which insures thatthe beam shall always ride per pendicularly, it being capable of rotation on the bolt a. Near the rear ends of the two inner bars, I, of each section I attach metal standards B, made of bar-iron sufficiently heavy to support the two bars I, to which they are at taehed, and maintain the two sections in the shape of an obtuse letter V inverted, as shown in Fig. 2, by means of bolts d, passing through the feet of the standards and the bars I, fastening them rigidly together.

The slot or opening in the standards B, I make adapted to receive a cross-bar, G, and through them I make holes 0, with corresponding holes in the cross-bar C, so made as to admit of bolts fastening the tops ofthe standards at any desired distance apart, while the two sections turn to the necessary extent upon the rod D, or bolts in lieu thereof. I thus make the bars K ride parallel with the sides of the ridge, whatever be theiraugle. Ithen adjust the bars I, which are carried next to the rows of corn,to the proper distance by-means of the slotted brace G. To the lugs or arms J,which pass next to the rows of corn,I attach a tendon board, A, sufficiently wide and long to prevent the eorn being buried. To this I bolt slotted reverse lugs a,to permit the board to be adjusted as to height,and also to enter the holes in J. To hold the fender-board in position I attach a slotted gage,b,which is merely a piece of bar-iron bent at right angles with the slotted portion thereof. The bent part of b strikes upon the bar I and maintains the board in any desired position.

The different parts may be made of any desired size,but for all ordinary purposes the bars IK and beam F may be of common bar-iron one and one-half or one and three-eighths inch by one-halfor three-eighths ofaninch. Imakethe bars I aboutthree feet long and Kabout one and one-half foot long. I make it all ofiron or other metal, except the handles and fender-boards. It is used as a cultivator,like the ordinary one, except that the horses are attached as if to a tongueless cultivator and the handles are manipulated in the rear. By pressing upon them the machine can be made to spread the dirt so as to cover the entire surface between the rows when they widen, and by raising the handles slightly the area of work can be considerably narrowed if irregular rows require. Thus by adjusting it properly and manipulating itcarefully the entire surface of a cornfield can be thoroughly cultivated and cleaned, as it cleans two rows at once. When used as a harrow, I remove the beam F, the handles E, set the gages B B C so that the sections are all in the same plane and work on the rod D as a pinion,and attach a chain, f, or other means of hitching thereto in such a manner that it will be drawn at an angle, when the teeth will cover the whole surface. IVhen used as a single harrow, I remove the shovel-beam F, attach the other handle in place of the beam, (and its braces L,) adjust the braces G, and use one horse.

I am aware that combined eultivators and harrow with gage attachments have been used, and I do not, therefore, claim such a combination, broadly; but What I do claim,and desire to secure by Letters Patent as my invention, is-

1. In a combined harrow and cultivator,thc side bars, I, harrowbars K, and sectional braces G, in combination with the clamp or gage B B O, perforated ears J, rod D, lugsn 0, shovel-beams F, clamp H, and handles E, substantially as shown and described.

2. The combination of the harrow-frameI K G, connecting-rod D, hinged feeder A, with stop or gage b, gage-clamp B B C, shovel-beam F, clamp H, and handles, substantially as shown and described.
