CGMBINED HARROW AND CULTlVATGR.

SPECIFICATION forming part of Letters Patent No. 273,697, dated March 6, 1883,

Application filed January 18, 1883.

- To all whom it may concern Be it known that I, LUTHER W. FILLE- BROWN, of Piqua, in the county of Miami and State of Ohio, have invented certain new and useful Improvements in a Combined Harrow and Cultivator; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Figure l is a side elevation of a harrowframe having my improved elastic harrowteeth secured to it. Fig. 2 is a bottom view of Fig. 1. Fig. 3 is a cross-section at line 0000, Fig. 2, showing a front view of my elastic tooth secured to a harrow-beam. Fig. 4 is a perspective view of the harrow-tooth. Fig. 5 is a perspective view of one of the T-headed bolts used to secure the harrow-teeth to their frame-beams.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to improvements on barrow blades or teeth which are adapted for pulverizing the surface soil, leveling the ground, and breaking up clods of earth; and the nature of my invention consists mainly in the peculiar construction and formation of a flexible elastic barrow-tooth and also in the combination of bolts having T-shaped heads with said teeth, for securing them to the beams of the harrow-frame, all of which will be fully understood from the following description, when taken in connection with the annexed drawings.

My improved elastic barrow-teeth are especially adapted to run in gangs, and for this reason I have represented one form of an angular frame or drag to which the teeth are applicable; but I neither claim as my invention nor confine my invention to the frame which I have shown.

A designates a central beam, and B B are transverse connecting bars or straps, which are rigidly secured to the said central beam by suitable bolts. The lateral extensions of these bars B B are pivoted to beams O G, which diverge from the center beam backwardly, and which are. held in the position (No model.)

shown in Fig. 2 by means of straps D D,which are diagonally arranged to sustain lateral strain in a direction with respect to their length, and which are linked at their outer ends to staples, and connected to a vertical screw that passes through the rear end of the central or draft beam, A. By means of a number of holes through the inner lapping ends of the straps D D (which are also braces) the degree of divergence of the beams O O can be adjusted, and the width of the barrow-frame changed according to the condition of the ground to be harrowed.

The front beveled ends of the side beams of the barrow-frame are guided and sustained against vertical displacement by transverse plates F F, which are rigidly secured to the top and bottom sides of the front end of the central draft-beam, A, and which extend over and beneath the side beams, (l O, in front of the pivotal connections of these beams, to the transverse straps B B.

Immediately in rear of the transverse plates F F, and rigidly secured to the central draftbeam, A, is a vertical transversely-slotted standard, Gr, through the slot of which a vertically-adjustable hook or eyebolt, (1, passes, which can be secured to the standard G at any desired height from the beam A by means of the binding-nut 01. Through the hook of the bolt d passes a draw-bar, H, which is linked at its rear end to a strap, 1, rigidly secured to the beam A on top thereof. The front end of the draw-bar H is provided with a swivel hitching ring, 0, adapted for attaching a double-tree. By adjusting the bolt (1 up or down the pitch of the harrow-frame will be changed by the draft of the team.

All of the barrow-teeth which I employ are constructed alike, and they are arranged in gangs, one behind the other, on the bottoms of the side bars or beams, O 0, one tooth being secured at or near the rear end of the central or draft beam, A, and secured to this beam in a more direct line than the teeth on the side beams. Each one of the teeth J is made of thin steel set in the form of the segment of a scroll, so that when it is secured to the harrowframe it resembles very closely the mold-board of a turn-plow inverted.

For the purpose of a more exact description of the tooth I will refer to its several peculiarities. The top of the blade is flat and has two flanges, g g, directed to the right and left hand, and perforated to receive through them bolts h h, which rigidly secure the tooth to its beam,and which are constructed withT-shaped heads h, the broad flattened sides of which impinge snugly against the sides of the tooth, at its junction with the flanges g g, and afford rigid abutments or stays for the blade,near the front and rear thereof. The front cuttingedge of each tooth extends from a p0int,p, backward to a central bearing or supporting point, p, in rear of which is formed the curved wing to.

The wings to of the teeth which are secured to the diverging bars or beams O O are respectively directed inwardly, or toward the center of the barrow-frame, and the wing to of the tooth which is secured 'to the central beam of the barrow-frame is directed either to the right or left.

It has been stated above that the blades of the teeth J are made of thin steel, that they are flexible and elastic, and that they are constructed with wings, like the mold-board of a turn-plow turned upside down. It will thus be seen that the teeth will operate as cutters or colters for cutting through clods of earth and preventing the accumulation of trash in front of them also, that they will yield when they meet with stumps, stones, and other obstructions, and pass the same without breaking or causing undue strain on the team.

It will also be seen that the teeth will operate as spreaders and levelers of the surface-soil, and also as clodbreakers, leaving the ground in good condition for receiving seed.

It will finally be seen that the T- shaped heads of the bolts h are beveled, so that they will not accumulate trash.

For some purposes I shall reverse the arrangement of the side-beam teeth and so apply them to the beams that they will direct the earth outwardly instead of in wardly as shown and described.

Havingdescribed myinvention, what I claim as new, and desire to secure byLetters Patent,

1. A barrow-tooth consisting of a thin elastic blade having the form of the segment ofa scroll, and constructed with a flexible wing and a backwardly-inclined cutting-edge terminating at its front end in a point, substantially in the manner and for the purposes described.

2. The combination of an elastic blade havin g the form of the mold-board of a turn-plow inverted, the elastic wing w, and the flanges 9, all constructed and adapted to operate substantially in the manner and for the purposes described.

3. The combination, with the elastic-winged barrow teeth having' perforated flattened flanges g g, of the securing-bolts h, having beveled T-heads, all constructed and adapted to operate substantially as and for the pur- Witnesses:
