WHEEL-HARROW,

SPECIFICATION forming part of Letters Patent 1 Io.359,478, dated March 15, 1887. Application filed Deember 2, 1886. Serial NodiZQfLfiOB. (No modell To all whom it may concern;

Be it known that I, J ULIUs A. VAN TA ssnL, a citizen of the United States of America, residing at Benona, in the county of Oceana and State of Michigan, have invented certain new and useful Improvements in \Vheelllarrows; 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, reference being had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in sulky-harrows, the object of my invention being to provide a sulky-harrow which is mounted on a suitable frame so that the center portion of the harrow, which carries the side wings,can be elevated and depressed by the driver.

My invention also consists in providing a central harrow with side wings which are pivoted thereto, so that they may be raised and lowered, said side wings being provided with extensible side pieces, whereby the width of the side sections may be increased.

My invention further consists in the construction and combination of the parts, as will be hereinafter fully set forth, and specifically pointed out in the claims.

In the accompanying drawings, which illustrate my invention, Figurel is a plan view of asulky-harrow constructed in accordance with my invention. Fig. 2, is a rear elevation. Fig. 3 is a sectional view taken through the line w 00 of Fig. 2, and Fig. 4 are detail views of spring-teeth which may be employed upon the barrow-sections.

In the accompanying drawings, A refers to a suitable rectangular frame, to the underside of which is rigidly attached an axle, a, said axle extending beyond the rectangular frame and carrying suitable supporting-wheels. The -rectangular frame hereinbefore referred to is made up of longitudinal side bars, a, and transverse bars b b 1) b*, all of said bars being rigidly attached to the longitudinal bars a in any suitable manner.

. The draft-tongue B is attached to the rectangular frame immediately above the crossbar I) and to the axle a, and said axle also serves as a support for the drivers seat B.

The central harrow section, 0, consists or is made up of side bars, 0 0, which lie immediately within the supporting-wheels, and to the side bars are attached,to the under side thereof, cross-bars c, c, d, and d, and between the rear cross-bar, c, and the next crossbar adjacent thereto are attached verticalstandards e, which are connected to each other at their upper ends by cross-bar 6, said standards being suitably braced to each other and to the barrow-frame by bars, as shown.

The corners of the central barrow-frame are provided with suitable straps with eyes,with which engage the pintles which project from similarly-constructed straps, so as to form a hinge-joint between the central harrowseetion and the side wings.

To the crossbar bis piv-- otally attached a lever, F, said lever at its rear-- wardly-projecting end being provided with. a link, which engages with a bar,j,which is pivotally attached to the cross-bar (Z of the central harrowsection, and when the hand-grasping portion of this lever F is depressed the rear portion of the barrow-section will be elevated, and may be maintained in an elevated position by causing the links 9, attached to the rear cross-bar, c, of the harrow,to engage with a hook, g, which projects from the rear side of the bar If. The front portion of the central harrow is attached to the supportingframe by means of depending bars h h, which engage with eyes h, attached to the front corners of the same, said bars it having a rearwardlyextending portion, h, which is attached to the axle by means of suitable eyebolts. By this construction the center harrow-frame is held relatively at the same dis tance from the supporting-frame when the rear portion is elevated or depressed. v

The lever F,for elevating or depressing the central harrow -frame,' may engage with a toothed segment or suitable curved bar for holding the same in position.

G and G refer to the side wings or sections, which are hinged to the central barrow-section, and these side wings areprovided at their outer ends with a rearwardly-tapering bar, g",

the front portion of the side wings being wider than the rear portion, as shown, and to the front outer corners are pivoted triangular sections H, which can be swung in and out from the main portion of the side wings, as shown in dotted lines. Both of the side wings G and G are provided on their under sides with caster-wheels i, said caster-wheels being located at the front outer ends. The extensible side wings, H, have attached near their rear ends bars I, which pass through bails i and loops i, the inner ends of these bars being formed into eyes, with which bars 1 engage, the inner ends of said bars being connected to levers J,

which are pivoted to one of the cross-bars of the frame A. By means of this lever theside section can be extended.

The main frame at the front corners is provided with hooks it, which will hold the side sections in a vertical position, as shown in Figs. 2 and 3, when they are raised.

1n transporting the harrow the side wings are elevated, as shown in Fig. 2, the extensible sections H being first brought snugly against the sections G, and by depressing the lever F the central and side sections will be raised at their rear ends, so as to be out of coir tact with the ground, and when the drivers weight is thrown upon the rear of the frame the main frame will be tilted upon the axle, so as to raise the frontportion of the harrow,

30 thereby bringing all of the teeth out of the ground.

ith the improved harrow hereinbefore described either springteeth, as shown in Fig.

4., may be employed, or the ordinary rigid teeth.

I claim- 1. In a harrow, a central frame provided with a tongue,an axle with supporting-wheels, a lever pivotally connected thereto for elevatingthe rear portion of the central section, said section having pivoted at each side thereof side wings, one of said side wings having a laterally-movable section,and means connected to a lever on the main frame for adjusting said section, substantially as shown.

2. In a wheel-harrow, a main frame pro vided with a lever, F, for elevating the rear portion of the central harrow section, side wings pivotally attached to said central section,tlie side wings carrying triangular sections H,and rodsI and l,for latcrallyextending the sections II, substantially as shown, and for the purpose specified.

In testimonywhereof I ailix mysignature in presence of two witnesses.
