SPECIFICATION forming part of Letters Patent N o. 659,576, dated October 9, 1900.

Application' ined February 13,1900. semi No. 5,096. No moar-.1.1

To all whom t may concern:

.Be it known that I, CHARLES D. CARTER, a citizen of the United States, residing at Spring Arbor, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Sulky or Riding Harrows, of

mits the harrow-sections to have a free verti-- cal movement within a predetermined downwardly-limited distance, all of which will be fully described hereinafter and particularly pointed out in the claims.

One object of my invention is to provide an improved support for harrow frames or sections whereby the said sections are more accurately supported and the depth of the teeth in the soil more certainly regulated over the whole area of the harrow section or sections by placing a third wheel in the center between the sections and which is so constructed and arranged that the barrow-sections are permitted a free vertical movement and the ieXibility of the sections entirely unimpaired.

Another object of my present invention is to provide the barrow-supporting attachment with means for supporting the seat, which is at a point considerably elevated and out of the dust and which will evenly distribute the weight or" the rider upon each of the three wheels, the said wheels adapted to run in an open furrow and the wheels being sufficiently removed from the teethv of the harrow-sections to prevent theharrow-teeth from throwing dirt upon the wheel-fellies.

Another object of my present invention pertains to providing a combined riding and supporting attachment `for harrows in which the supporting-axle is made in sections, whereby the wheels are permitted a free and independent movement and at the same time equally distribute the weight of the rider upon the said wheels.

The object of my invention also pertains to certain details of construction, which will be fully described hereinafter and particularly referred to in the claims.

In the accompanying drawings, Figure l is a perspective View of my invention,showing it connected with two harrow-sections, the front ends of the harrows being supported by a tongue. Fig'. 2 is a transverse central sectional view of Fig. l. Fig. 3 isa perspective View of my invention, showing it applied and constructed to have the front ends of the harrows supported by suitable shoes, in which event the tongue shown in-Figs. l and 2 is omitted. Fig. 4 is an enlarged detached perspective view of the adjacent sides of the front ends of the harrows, `showing the pivotal bolt or pin provided with a roller. Fig. 5 is a detached perspective view of the U- shaped guide serving to connect the inner rear portions of the barrow-sections to the vertically-extending seat-standards.

Referring now to the accompanying drawings, A indicates two harrow-sections which may be of any desired form, the said harrowsections being here shown with depending` toothed bar-brackets B, in which the springtooth bars C are suitably journaled, the said tooth-bars carrying any desired form of tooth D. These tooth-bars C are here shown with vertically-arranged cranks E, which are connected by m'eans of a horizontal elongated link F. To one of the tooth-bars C (here shown as the rear one) a vertically-arranged lever Gr is attached, the said lever carrying the ordinary spring-catch H, adapted to engage a toothed segment I. The function of this construction is well understood and is for the purpose of raising or lowering the spring-teeth D by oscillating the rocking oroscillating tooth-supporting bars C. The construction thus far described is old and well known. I

My invention pertains to providing a combined supporting and riding attachment for the harrow-sections, and consists in extending under the rear portions of the harrowsections a supporting-shaft K. This shaft K is divided into the two end sections L and a central section M. The central section M has journaled thereon a central supportingwheel N, whichv is arranged between the two harrow-sections, as clearly shown in Figs. l and 3. The end sections L of the supportingshaft carry at their outer ends the end supporting-wheels P, the said end supportingwheels being situated outside of the frames of the barrow-sections, as is also clearly illustrated in Figs.` l and 3.

Projecting upward from the central section M is a seat-standard Q, the said seat-stan dard being here shown as a single fiat bar of iron doubled at its. 4upper end and provided wit-h downwardly-extending parallel portions having their lower ends suitably connected with the central section M of the supporting-shaft K, thus constituting an essentially inverted- U-shaped standard, For the purpose of supporting this standard in a vertical position I provide lon gitudinally-extendin g brace-rods R, the upper ends of the brace-rods being pivotally connected to the opposite sides of the seat-standard Q and their lower ends pivotally connected with the barrow-section A. As here shown and as I prefer, these braces R extend forward and have their forward and lower ends pivotallyconnected to theinner sides of the front ends of the harrowsections, as clearly illustrated. It will be thus seen that these braces R serve to support the seat-standard' Q in a vertical position.

The inner, rear, and front sides of the harrow-sections are hinged together, as shown at a., whereby they are flexibly connected, and the outer sides of the barrow-frames are provided with the downwardly-extending loops b, which embrace the adjacent portions of the end sections of the supporting-shaft, and thus loosely connect the outer sides of the harrow-sections with the supporting-shaft to permit the barrow-sections to have a free vertical movement independent of the supporting-shaft. The inner sides of these harrow-sections are preferably connected wit-h the parallel sides or portions of the seatstandard Q, and in this event theyare provided with the inwardly-extending U-shaped connections S, which embrace the said vertical parallel portions of the standard Q, as clearly shown. Since the draft is through the barrow-sections and upon a combined supporting and riding attachment, for the purpose of preventing any binding upon the attachment S, I provide these U-shaped attachments with rollers T, which engage the rear edges of the vertical portions of the seatstandard Q, and thus permit the sections a free vertical movement independent of the supporting-shaft and avoid any possibility of the binding of these parts under the draft caused when drawing the harrow.

In Figs. l and 2 I show another attachment, which consists of a tongue c, the said tongue being provided with rearwardly-extending arms d, which have their rear ends suitably connected to opposite sides of the vertically-disposed seat-standard Q, and theV forward ends of these bars d extend downward, as shown at e, and constitute a vertical slot or guide f, into which a roller g, arranged upon the pivotal point or pin at the front end of the harrows, extends, and thus serves as a guide. The specific construction of this vertically-disposed tongue-guide and the arms d consists of forming the same of a single piece of dat bar metal doubled intermediate of its ends to constitute the guide f and then turned backward and secured to i the tongue c, with the rear ends attached to the vertically-disposed seat-standard Q, all of which is clearly shown in the accompanying drawings.

In Fig. 3 I show my riding and supporting attachment adapted to be used without a tongue c and in which event the usual supporting-shoes 't' are used for the front ends of the harrow-sections, but in which event the harroW-sections are still permitted to have a free up-and-down movement independent of the supporting and riding attachment.

In Figs. l and 2 I show a means which is operated and controlled by the oscillating or rocking tooth-bars C for lifting and supporting the front end of the barrow-sections when the harrow is being transported. This consists inV providing the front tooth-bars C with a forwardly extending arm or lever Z, to which is connected the end of a chain j, the upper end of the chain adapted to be caught over a suitable hook k, which is suspended from the tongue c. From this it will be readily understood that when the harrowteeth E are elevated by the oscillating of the tooth-har C the forward end of the lever Z is carried downward, which lifts the front end of the barrow-section upward and serves to support the same.

Owing to the sectional supporting-axle K, it will be readily understood that the end su pporting-Wheels P are permitted to have a free vertical movement independent of each other and also a free independent movementin respect to the central wheel M and that the central wheel M is permitted to have a free vertical movement independent of the end wheels. For the purpose of having the weight of the rider equally divided upon the three Wheels at all times I provide a seatsupport which is connected with the end sections L of the supporting-shaft K and which therefore divides the weight between the three wheels. This arrangement consists in providing a vertically-arranged rod 2, which Vpasses through an opening in the upper doubled portion of the seat-standard Q, the upper end of the said rod 2 being pivotally `connected with the upper and inner ends of lthe weight-receiving braces 3, the lower ends i of the said weight-receiving braces being pivotall y connected to suitable clips 4, which are attached to the end sections L of the supiporting-shaft at points intermediate of their lends. The rod 2 has a free vertical movement through the upper end of the seatstandard Q, and when either of the end Wheels 'P moves upward the rod 2 is moved only onethird of the distance of the movement of the Wheel. Attached to the lowerend of this rod 2 is a seat-attaching socket 5, the said socket IZO having grooves adapted to receive the side portion of the seat-standard Q and to have a seat-spring 6 suitably bolted to the under side thereof, the said seat-spring carrying a seat 7 at its upper end. From this description it will be at once understood that when either one of the wheels P moves vertically by striking a stone or other obstruction the rider is lifted and the Weight through the medium of the Weight-receiving braces 3 is equally distributed upon the three supporting-Wheels and that owing to the point of attachment of the braces 3 to the end sections Lof the supporting-shaft the vertical movement of the rider is but about one-third of the vertical movement of the supporting-wheels.

I am aware that it is old to provide a combined supporting and riding attachment for harrows; but in this event they have been provided With two Wheels, and I find in practice that the two Wheels are not sufcientto support the Weight of the driver and of the harrow Without making considerable traction and therefore making the draft of the harrow heavy. By providing three Wheels, as here shown, and arranging the Weight of the rider equally upon each of the Wheels I am able to make a construction Which is of a light draft and which is also adapted to accurately support the harrow sections at an even heighth from the ground over the Whole width of the tool.

It will be gathered from the above description that my invention is especially adapted to be used in connection with spring-toothed harrows, which it is found are advantageously supported a considerable distance above the surface to permita freer play of the spring-teeth and also to have the supporting attachment carry the rider and to support the sections of the harroW in an improved and advantageous manner.
