RVERSlBLE HARROW.
SPECIFICATIN 'forming part of Letters Patent No. 350,893, dated Oetelaar 12, 1538A Application filed May Q9, 1886. Sc1ialNo.20l,637. (No model.)
To all whom it may concern:
Beit known that I, Wrrmrur S. Parras, of Jouesburg, in the county of Montgomery and State of Missouri, have invented a certain new and useful Improvement in Reversible Harrows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure l is a perspective view of my reversible harrow. Fig. 2 is an enlarged perspective View of one of the vertical shoulder blocks that brace the teeth in their vertical and inclined positions; and Figs. 3, el, and 5 are longitudinal sections, showing the relative situation of the teeth in their inclined vertical and closed positions.
)ly invention relates to improvements in reversible-tooth hai-rows, which are adjustable in vertical, inclined, and closed positions; and my invention consists in features of novelty hereinafter l'ully described, and pointed out in the claims.
Referring to the drawings, in which similar letters ol' reference indicate like parts, a represents my reversible hai-row, provided with the teeth l) in their vertical position. C are my vertical abutment-blocks, located on one side of the teeth. The teeth are reversible, and are pivoted between longitudinal twin bars B 13 by pins D, that pass through both bars and teeth. There are a series of these twin bars connected by rods E at suitable distances, the number ot' the bars being contingent on the width it is desired to construct the harrow. The rods are provided with sleeves E, that surround them between the longitudinal bars, and which, with the rods, tightly clamp said bars and are secured by nuts EE at their ends, and when the harrow is of more than a single section, they are connected by hooks E3 at the ends of said rods. Heavier draft-rods F connect the bars at the ends of the harrow and pass through said bars and their intermediate abutment-blocks, C, and, like the other connecting-rods, are provided with sleeves F, that till the spaces between the bars. Draft-clevises G are secured to the d raft-rods F, and where they grasp said rods inclose ends of the longitudinal bars within their grip. The teeth have free pivotal to withstand the action until they are braced by the abutmentblocks C, which have vertical faces C', and inclined ones (It, that hold the teeth relatively in vertical and inclined positions, the change of position from one to the other being obtained by inverting the barrow. The face edges of the blocks are also provided with concave recesses C, iu which the circular' heads ofthe teeth work. The third position, that of the closed teeth, in 'which they are re tired between the bars, is effected by attaching therdraft to the reverse end of the harrow to that used in working the ground. When in this closed position the teeth trail upon the ground. To place the teeth in working position the harrow is lifted sufficiently at the draft end to permit the teeth bytheir own gravity to return to working position. blocks are provided with flanges C, that grip the edges of the longitudinal bars above and below, and which, in conjunction with the rods that pass through both bars and blocks, rmly brace and securely hold the several parts together, and at the same time the flanges brace the blocks themselves and enable them pressure ot the teeth against them.
I prefer to make the bars or frames of iron; but I do not confine myself to the use of that material, as they may be made of wood, or any other suitable material, without departing from the essential features of my invention; neither do l confine myself to the number ot' bars and section-frames shown, as the harrows can be constructed either with more or less bars and sections to suit the nature of the ground to be worked.
It will be seen that the conjoint use of the abutment-blocks with their iianges bracing and gripping the bars, in combination with the rods andtheir sleeves, makes a strongly-braced and durable barrow-frame. It is easily reversible from a vertical (see Figs. 1 and 4) to an inclined tooth or smoothing harrow (see Fig. 3) by simply inverting the harrow. It has also another useful transformation, (shown in Fig. 5,) in which by hitching the team to the other end of the harrow, the teeth turning on their pivots retire between the bars. This feature of the invention enables it to slide smoothly on the ground when passing over Thel ICO
grass thatit is not desired to tearv up in pasture or meadows, or when in course of removal from eld to field.
I claim as my invention- 5 1. The combination of a bar, B, a reversible tooth, D, having a circular head pivoted thereto, and a block, C, located on one side of the tooth, having a vertical face, C, inclined face G2, and recess C`L between the faces, the recess being occupied by the circular head, substantially as described.
2. The combination of twin bars B, a block, C, having` vertical face C, recess 0*, inclined face C2, and flanges C3, means by which the I5 block is secured from longitudinal movement I between the bars, substantially as described.
