Application filed October 26, 1897. Serial No. 656,468. (No model.)

To aZZ whom it may concern;

Be it known that I, EFFINGER E.-WHIPPLE,

a citizen of the United States, residing at,

Utica, in the county of Oneida and Stateof New York, have invented certain new and useful Improvements in Supporting Attachments for Harrows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in riding or supporting attachments for harrows or other soil-working implements.

The objects and nature of the invention will appear hereinafter; and the invention consists in certain novel features in construction and in arrangements and in combinations of parts,as more fully and particularly described and pointed out hereinafter.

Referring to the accompanying drawings, Figure 1 is a top plan view of a two-section lever-adj ustment harrow provided with a construction illustrating an example of my invention. Fig. 2 is a side'elevation thereof, the teeth being lowered, the rear portion of one harrow-section being partially broken away to show the supporting device. Fig. 3 is a View corresponding to Fig. 2, but showing the teeth elevated. Fig. 4. is a detail perspective of a form of the riding or'supporting attachment which can be employed. Fig. 5 is a perspective of portions of the rear ends of the two harrow-sections and of the supporting or riding attachment. Fig. 6 is a detail view of a portion of the draft-tongue or stick of the attachment, showing adjustable loops for the standards from the harrowframe and means whereby said loops can be tightened or loosened to prevent or permit lateral play ofthe standards. Fig. 7 shows a modification whereby loose connections or supports depend from the tongue to the harrow-frame and wherein the front end of the tongue can be spread or braced against lateral play.

In the drawings a two-section harrow of any desirable construction is shown. Each section is formed with its frame a and rocking tooth-bars b, carrying teeth b. Each section has also lever adjusting or operating means for rocking the tooth-bars to raise and lower the teeth. Any means can be provided for this purpose, the ordinary means being shown, comprising the upright lever c, rigid with a tooth-bar and carrying a locking-pawl engaging a segmental rack on the adj ustingbar, pivotally joined to standards from the remaining tooth-bars of the section. Those skilled in the art understand the operation of such a device. An evener-bar d can be arranged in front of both of the harrow-sections and independently coupled to each section loosely or otherwise, according to circumstances. The draft is attached to the evener bar, although of course it is not necessary to my invention that the evener-bar be employed. be provided for the front ends of the sections, such as depending shoes or rollers. The har row-sections preferably are not directly coupled together in rear of the evener-bar, so that they can have certain free up-and-down play, although this is not essential to my invention.

The riding or supporting attachment comprises a draft-tongue or seat-stick f, arranged centrally of the two harrow-sections in the line of draftthat is, the stick is preferably arranged horizontally above the space between the two sections and extending from the front part of the harrow to the after part thereof. The tongue is usually formed of a straight stick or bar with an extension from its front endextended downwardly and loosely coupled to a forward part of the harrow. The drawings show the front end of the tongue coupled to the center portion of the evener-bar; but coupling to the evenerbar is not essential to the invention, as the front end of the tongue can be coupled at other. points at the forward portion of the harrow. The rear end of the tongue is carried by a supporting-wheel g, which is usually located in rear of the center of the harrow, and the rear end of the tongue is preferably held elevated by plates or bars 9', secured rigidly to the tongue and depending therefrom, with the supporting-wheel mounted in and between them. The tongue carries a seat f, usually arranged'in rear of thevertical plane, including the axis of the supporting-wheel g, although this location is not essential to the invention. Nor is it essential to Suitable supporting devices 6 can ICO the invention that the tongue carry a seat, although such is preferred practically.

Suitable means are provided to support or sustain the inner sides or portions of the harrow-sections at their after parts from said tongue, while the harrow-sections can be and are provided with supporting means at the after parts of their outer sides or portions such as depending shoes 72. from the frame, as shown in Fig. 2, or supporting-rollers h, suitably mounted, as shown in other figures of the drawingsso that when the teeth of either or both harrow-sections are elevated the tongue will carry the after part of the inner side of a section, while the outer side and front supports carried by the sections will uphold the remainder of the weight of the frame and parts. Various means can be provided to partially support the inner sides of the sections from the tongue when the teeth are elevated. For instance, the inner sides of the rear portions of the frames of the harrow-sections can be provided with rigid vertical standards '5, preferably parallel and extending upwardly on opposite sides, respectively, of the tongue and to points above the same. The tongue is provided with rigid side loops oropenings t", through which said standards pass and reciprocate vertically within certain bounds, and whereby the tongue is held against excessive lateral play. The loops can be formed to permit limited lateral tilting or play of the standards, if so desired, whereby the sections can rock laterally within certain bounds. The loops can be entirely rigid, as shown in Fig. 4, or can be formed of plates mounted and slidable in and out on parallel bolts rigid with the tongue and provided with adjusting-nuts at the outer sides of the plates, as shown in Fig. 7, whereby the nuts can be turned up on the bolts to press the plates toward the standards and limit or prevent lateral play thereof inclependent of the tongue, or on loosening the nuts greater play of the standards and harrowsections independent of the tongue is allowed. Suitable means of various constructions can be provided to limit the downward movement of the standards, and consequently uphold the harrow-sections when a certain distance below the tongue. For instance, the standards can be provided with series of transverse holes through which a pin t can be passed above the loop of the tongue to form a stop against further downward movement of the standard and permitting adjustment. The standard could be locked or limited in other ways. Also instead of the rigid standards loose connections, such as shown in Fig. 7, could be employed. In this figure chains j are shown attached to the tongue and to the inner sides of the frames of the harrow-sections to uphold the same. The chains are formed of the proper length or made capable of adjustment to permit independent upward movement of the sections and yet limit their downward movement. lVhere such a loose supporting connection is employed, the front end of the tongue can be forked or braced and secured to the evcnerbar or other part of the harrow at separated points to hold the tongue against excessive lateral play.

If it is desired to throw the weight of the riding or supporting attachment into the harrow, the standards can be secured to the tongue against the movement independently thereof, as by passing the stop-pins directly through the loops and standards.

I do not desire to limit myself to the exact arrangement of independent riding attachment shown nor to the location or method of attachment of the seat-stick or tongue f nor to any specific or particular means for supporting the rear end of said riding or supporting attachment. In a two-section harrow this arrangement of seat-stick has been found to be very effective; but it might be changed, and also the standards 2' 'a' are not necessarily secured rigidly to the harrow-sections.

By means of my invention a very simple and elfective and yet light-riding attachment is provided which is practically independent of the harrowthat is, the harrow has the proper or desired play independent of the riding attachment, and the curved spring-teeth can be forced down and the harrow-frame elevated by the rider without leaving his seat-and also by employing a harrow with frame-supports carried by and moving with the harrow while a portion of the frame is carried by the riding attachment many practical advantages are attained.

It is evident that various changes might be made in the forms, constructions, and arrangements of the parts described without departing from the spirit and scope of my invention. Hence I do not wish to limit the illvention to exactly what is described and shown, but consider myself entitled to all such changes as fall within the spirit and scope of the invention.

lVhat I claim is 1. A harrow having freely-movable sections, in combination with a wheeled support extending over the space between tl1e,sections, the inner sides of the sections having standards extending up andloosely confined to said support and provided with means to limit the downward movement of the standards and sections independently of the support, substantially as described.
