HARROW.

Specification of Letters Patent.

Application filed. September 25, 1909.

Patented Mar. 1 1, 1911. Serial No. 519,509.

To all whom it may concern:

Be it known that we, AnoLPH SoHLnY and RUDOLPH EDWARD SGI-ILEY, citizens of the United States, residing at Beaver Dam, county of Dodge, and State of Wisconsin, have invented new and useful Improvements in Harrows, of which the following is a specification.

Our invention relates to improvements in that class of harrows, provided with drag teeth and rocking beams, whereby said teeth may be adjusted into and out of position of use. In the harrows of this class, attempts have heretofore been made to provide connecting members for the rocking beams, which, when the teeth are out of position for use, will serve as shoes to hold the beams above the surface of the ground, but such attempts have, so far as we are aware, not been successful, for the reason that the connecting members, or the means for attaching them to the beams, were easily broken or disengaged from the beams.

The object of our invention is to provide a form of construction, in which there will be substantially no tendency to break the connections and in which the shoes will present a substantial runner surface for contact with the ground.

In the following description, reference is' had to the accompanying drawings, in which Figure 1 is a side view of a harrow embodying our invention. Fig. 2 is a detail plan view, showing the end of one of the rocking beams and a portion of a shoe connected therewith, the latter being partially illustrated in horizontal section drawn through its connection with the beam. Fig. 3 is a front View of the same, showing the shoe in cross section, drawn through its connection with the beam. Fig. 4 is a detail view of the outer surface of the connecting cap member, showing the square socket for receiving the connecting bolt.

Like parts are identified by the same reference characters throughout the several views.

The rocker beams A, teeth B, actuating arms C, connecting bars D and manually actuated lever E, may all be of any ordinary construction. In the harrow illustrated, the teeth are moved to inoperative position by means of the lever E, which actuates the connecting bars D forwardly, permitting the beams A to tilt forwardly and down wardly over the harrow teeth, which serve as fulcrums until the beams, or shoe bars connected therewith, are brought into contact with the ground, after which the beams rock upon the ground, or upon such shoe bars, to raise the points of the harrow teeth and adjust such teeth to a horizontal posi-' tion. We provide the ends of each beam A with a metallic cap F, in which the beam is socketed at G and to which it is bolted by a bolt f. This cap member is provided with a forwardly projecting ear H, having an aperture surrounded by outwardly projecting apertured boss it, which is adapted to fit suitable apertures in the shoe or bar I, which shoe or bar serves as a connecting member at the respective ends of the beams A. A connecting bolt J, preferably an ordinary carriage bolt, is inserted through the boss h with its head preferably bearing upon a washer K interposed between the head of the bolt and the end of the boss 7L, and a nut L is screwed upon the inner end of the bolt J and bears upon the inner surface of the ear H. The bolt J near the head H is square in cross section, and the aperture in the boss h is similarly formed, whereby the bolt is prevented from turning. The washer K i does not come in contact with the shoe I, but

bears against the end of the boss h and therefore there will be no tendency for the bolt J to vibrate or loosen, or for the nut L to unscrew.

The shoe or bar I is preferably formed of channel iron, having its central portion con nected, as above described, to the ears H, and with upper and lower outwardly projecting flanges which protect the boss 72 and the bolt J. The lower flange also provides a runner surface for contact with the ground, when the beams A are rotated to a position with the ears I-I extending downwardly therefrom. It will be observed that the ear H projects forwardly but not outwardly from the head of the cap plate F and that it is located upon the front wall of the cap plate, midway between the top and bottom of the beam in its normal position of use, the outer surface of the car being in the same plane as the outer surface of the cap plate. It is 7 therefore obvious that the cap plates F may be applied to either end of the beam, beingwardly, the ears H will turn toward a vertical position, and when the shoe bars I come into contact with the ground, a further ro-' tation of the beams A will cause them to lift or swing upwardly to a point where the ears vH occupy a vertical position with the beams r A above the bosses h.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is t 1. In a harrow having toothed beams and means'for rocking the same to adjust the teeth into and out of operative position, the

combination with said beams, of metallic end caps therefor, projections on said caps, each having an outer surface substantially in the plane of the outer surface of the cap and provided with an apertured boss extending outwardly from said surface, a bar having apertures in which the bosses of the projections are journaled, and bolts extending through said bosses and connecting said bar with the projections of the several beam caps, said projections being so located that the lower margins of said bars will be below the beams when the teeth are out of operative position.

2. In a harrow having toothed beams and means for rocking the same to adjust the teeth into and out of operative position, the combination with said beams, of metallic end caps therefor, projections on said caps, each having an outer surface substantially in the plane of the outersurface of the cap and provided with an apertured boss extending outwardly from said surface, a'bar having apertures in which the bosses of the projections are journaled, and bolts extending through said bosses and connecting said bar with the projections of the several beam caps, said projections being arranged to project forwardly from the beams when the harrow teeth are in operative position, and downwardly when the teeth are in an inoperative position.

3. In a harrow having toothed beams and means for rocking the same to adjust the teeth into and out of operative position, the com bination with said beams, of metallic end caps therefor, projections on said caps, each having an outer surface substantially in the plane of the outer surface of the cap and provided with an apertured boss extending outwardly from said surface, a bar having apertures in which the bosses of the projections are journaled, and boltsextending through said bosses and connecting said bar with the projections of the several beam caps, said projections being arranged to pro ect forwardly from the beams when the harrow teeth are in operative position, and downwardly when the teeth are in an inoperative position, and said bars being formed of channel iron with flanges above and below said bosses to protect them from injury. ,7 I

4. In a harrow having toothed beams and means for rocking the same to adjust the teeth into and out of operative position, the combination with said beams, of metallic end caps therefor, projections on said caps, each having an outer surface substantially in the plane of the outer surface of the cap and provided with an apertured boss extending outwardly from said surface, a bar having apertures in which the bosses of the projections are journaled, and bolts extending through said bosses and connecting said bar with the projections of the several beam caps, said projections being so located that the lower margins of said bars will be below the beams when the teeth are out of operative position, said bolts having corner proj ections engaging correspondingly shaped portions of the boss apertures.

5. In a harrow having toothed beams and means for rocking the same to adjust the teeth into andout of operative position, the combination with said beams, of metallic end caps therefor, projections on said caps, each having an outer surface substantially in the plane of the outer surface of the cap and provided with an apertured boss extending outwardly from said surface, a bar having apertures in which the bosses of the projections are journaled, and bolts extending through said bosses and connecting said bar with the projections of the several beam caps, said projections being so located'that the lower margins of said bars will be below the beams when the teeth are out of operative position, said projections extending from the center of the front margin of the outer wall of said cap, whereby like caps may be adjusted to either end of the beam.

6. In a harrow having toothed beams and means for rocking the same to adjust the teeth into and out of operative position, the combination with 1 said beams, of metallic end caps therefor, projections on said caps provided with outwardly projecting bosses, connecting bars, journaled on said bosses, and bolts extending through the bosses, and through said projections, said bolts being non-rotatably engaged in said bosses.
