Specification of Letters Patent. Patented Oct 13, 1914;.
Application filed February 4, 1914. Serial No. 816,472.
To all whom it may concern citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certaln new and useful Improvements in Cult-1 vators, of which the following is a specification. i r
This invention relates to cultivators and particularly to so-called hand-cultivators, that is to say, cultivators of the class employed for lighterkinds-of work and adapted to be pushed over the ground generally without the assistance of a draft'animal.
According to my invention I pivot to a suitable rigid frame, having a supporting wheel at the front and handles at the rear,-
said structure preferably comprising two slender flexible side strips joined at their rear ends by a relatively heavy head in which are mounted the soil-workingbtools. In the accompanying drawings, Figure 1 is a side elevation of the improved cultivator; Fig. 2 is a plan view thereof; Fig. 3 is a side elevation of the forward portion of the cultivator with a certain draft yoke 5 turned forward; Fig. 4 is a planview of the structure aforesaid; Fig. 5 is a rear elevation of said structure; Fig. 6 is a similar elevation, showing the disks 2 removed and an extension piece attached; Fig. 7 is a plan of one of the extension pieces; and, Fig. 8 is a perspective view of the mulching tool.
The frame includes the side bars a converging forwardly and held in rigid relation to each other by two or more crosspieces I), the said side bars at their rear ends affording handles 0 and at their forward ends being provided with the axle a?v for the supporting wheel 6, the ends of said axle protruding through the said bars for a purpose to be explained. The pivoted structure aforesaid is constructed as follows: f f designates two metallic strips spaced apart and having substantially the same convergence as the side bars a and arranged with their broad surfaces facing laterally. At their more widely spaced ends they are bolted to the forwardly projecting lugs g of a relatively heavy metallic casting it forming a crossbar carrying the soilworking implements. Each lug 9 forms a part of an angular projection} of the cross- Be it known that I, Tron C. 'KEVITT, a

the horizontal holes 70 "adapted to receive a the tongues Z of the extensions m, each havthe'end of the cross-bar h and its projection 1:. Any suitable means, such. as the set screws 7) tapped into the cross-bar and bearing against the tongues Z, maybe employed to secure the extensions in" place. The effective width of thecross-bar and its extensions maybe increased-by arranging the innermost tongues on the extensions in theoutermost holes is in the crossbar, as
will be obvious.
The cross-bar and its extensions are provided .with arow of vertical holes 9 and -Preferably the cross-bar is provided with with the downwardly projecting sockets r in which are received the teeth 8, held in place by the set screws t. Similar holes 14 in the cross-bar, provided with sockets 4;, may recelve the vertical stems to of: a horizontal mulch-bar w, said stems being held in place .by the set-screws y. The mulch bar being placed behind the row of teeth 8 and slightly higher than the lower ends thereof is peculiarly advantageous in mulching the soil after it has been harrowed by the teeth. It will be understood that both the teeth and the mulch barmay be adjusted to any desired elevation.
If desired, axles z for the disk knives 2 may be secured on the cross-bar h by the screws 3, said knives being useful in cutting ofl' runners from plants and other similar purposes.
The structure just. described is pivoted in the frame shown in the drawings, or any other suitable support, so that it trails. To this end 4 is a bolt penetrating the side bars a of said frame and the forward ends of the strips f. Owing to the fact that said structure is pivoted and trails, and because its strips f are flexible, laterally, as it is trailed over the ground it can clear unyieldless as shown in dotted lines in Fig. 6, so
that only the teeth which directly engage the obstacle leaves the ground. I find in practice that the adaptability of the trailing structure to clear obstructions without the .bolts 6 at the forward ends of the side bars 0;. I
On the frame may be arranged a barrow,
7, at which time the yoke 5 is swung for Ward, resting on the ends of the axle d.
8 is a chain attached to the pivoted structure for use in raising the same as occasion requires; the pivoted structure may be held elevated as shown in dotted lines in Fig. 1 by attaching one of the links of the chain to the hook9 on the frame.
The disk knives 2 not only serve for the purpose already explained but to support the trailing structure, so that the teeth harrowlthe ground at a more or less uniform depth. (They nevertheless offer no appre- Ciable resistance to the lateral movements of the trailing structure because usually when an obstruction is met and the trailing structure shifts laterally only one of them is received in the ground, the other being more or less elevated by the obstruction).
The'mulchbar also serves, to preserve the teeth at a substantially uniform working depth, as will be obvious.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination, a frame having handles at its rear end, a supporting wheel for the frame arranged at the forward end of the frame, and a trailing soil-working structure movable up and down and being freely flexible laterally and including a pair of slender laterally flexible side strips pivoted at their forward ends to said frame, a relatively heavy cross-bar connecting said strips and arranged substantially at their rearward extremities, and soil-working tools arranged in said crossbar.
2. In a trailing soil-working structure, an elongated tool-holding member adapted to extend crosswise of its path of travel when in use, an extension projecting beyond one end of said member and adjustable longitudinally of the latter, said member and extension having interchangeable interlocking portions, means to hold the extension to said member, and soil-working tools carried by both said member and the extension.
In testimony whereof I afiix my signature in presence of two witnesses.
