HARROW OR CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 770,992, dated p e r 27, 1904.

Application filed January 4, 1904:.

To all whom it may concern.-

Be it known that I, HARRY URBAN WAKE- FIELD, a citizen of the United States, residing at Cornersville, in the county of Marshall and State of Tennessee, have invented a new and useful Harrow or (Jultivator,of which the following is a specification.

This invention relates to harrows and cultivators; and it has for its object to provide an implement of this class which by simply using the proper earth-engaging elements may be utilized either as a harrow or as a cultivator, the invention residing in the improved construction,arrangement, and disposition of the parts constituting the frame of the device.

The object of my invention is to provide an improved harrow or cultivator frame which shall be simple in construction, easily operated, adapted to operate between the rows of growing plants, so as to take in the entire width between the rows, which shall be capable of adjustment so as to fit the implement to operate between rows growing at various distances apart, and which shall be capable of being easily adjusted and manipulated.

With these and other ends in view, which will suggest themselves as the nature of the invention is better understood, the invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described,and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View of my improved device, showing the same equipped with cultivator blades. Fig. 2 is a vertical longitudinal sectional view taken on the line 2 2 in Fig. 1. Fig. 3 is a transverse sectional view taken on the line 3 3 in Fig. 1.

extended some distance in front of the side Serial No. 187,680. (No model.)

connected therewith by means of a bolt 6,

which latter also serves for the attachment of a bracket 7 which may be, and as shown in the drawings is, in the nature of a bail, having a vertically-disposed front piece 8,pierced by a plurality of perforations 9 for the attachment of a cross-bar 10, which latter is provided with a centrally-disposed seat 11, having side flanges 12, engaging the edges of the front bar 8 of the bail, so as to reinforce the parts. At the ends of the cross-bar 10 are horiZontally-disposed slots 13.

Firmly bolted to the outer sides of the side bars 1 and 2 are a pair of angular brackets 1 1, the front sides of which are provided with pluralities of perforations 15 for the reception of eyebolts 16, which latter are obviously adapted for adjustable connection with the front sides of the brackets lt. These eyebolts are connected, by means of links 17, with a ring or clevis 18, to which the draft is attached. One of the main side beams, 1, is provided with a notched segment 19, which extends under a guard-plate 20 upon the side beam 2, and upon the latter is mounted a slidable spring-actuated rod 21, terminating in a dog or pawl 22, adapted to engage any one of the notches in the segment-bar 19. It is obvious that when the dog 22 is released from engagement with the segment-bar the side beams 1 and 2 may be spread apart or moved in the direction of each other at their rear ends, and that when the proper adjustment has been attained the said side beams may be secured with relation to each other by simply causing the dog 22 to engage the proper notch of the segment 19. Suitably secured to or connected with the side beams 1 and 2 are the handles 23. At the connecting-point of the handle 23 with the side beam 2 the rod 21, having the dog 22, is flexibly connected with an operating-rod 24, which is disposed alongside the handle 23, to which it is attached by means of staples 25, constituting guides. The flexible connection between the rods 21 and 24; and which is designated 26 is to be guided and supported in any suitable manner, as will be readily understood.

Suitably connected with the side beams of the device are the earth-engaging elements 27 and 28, of which any desired number may be used, the shank of the front or central earth-engaging element 28 being secured near the front end of the beam 2, which for this purpose is extended in front of the beam 1. Under some circumstances, especially when the earth-engagin g element 28 is not used, it is desirable to attach an ordinary harrow-tooth,

such as shown at 35 in Fig. 7, to the extended front end 3 of the side beam 2. Such a tooth may be secured in position by means of an ordinary clip 36, and when used it is permitted to extend downwardly through an opening 29, which is formed for the accommodation thereof in the lower part of the bail or bracket 7 said opening being of suflicient size to admit of the lateral movement within it of the tooth 35 when the hingedly-connected side beams 1 and 2 are adjusted. hen the auxiliary tooth 35 is not to be used, the opening 29 in the bail 7 may be dispensed with.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood. .The construction is light and simple, and the device may be ad justed to operate between the rows of growing plants no matter how close together or how far apart they may be. It is frequently desirable that the side beams should be adjustable under the control of the operator while the device is in operation, and this may be easily effected by simply disengaging the dog 22 from the segment-raek 19 and securing it temporarily in this disengaged position, when the operator by manipulating the handles of the device may readily adjust the same to the requirements of the circumstances. I/Vhen draft is exerted upon the draft-ring at the front ends of the links 17, the tendency will be for the side bars to be drawn apart at their rear ends, if not locked together; but this tendency will be counteracted by the resistance of the soil to the earthengaging element and will involve no strain upon the operator or upon the parts of the device. At the same time it will be seen that the links 17 are guided by and have free play in the slots 13 at the ends of the cross-bar 12. The latter, as will be understood, may also be readily elevated or lowered for the purpose of adjusting the draft.

The several parts of my invention are simple in construction, easily assembled, and the device may be very easily and conveniently operated for the purposes set forth.

I desire it to be understood that while I have in the foregoing described a simple and preferred form of my invention I do not thereby limit myself to the precise structural details herein set forth, but reserve the right to any changes, alterations, and modifications which may be resorted to within the scope of my invention and without departing from the spirit or sacrificing the utility of the same.

Having thus described my invention, I claim-- 1. In a device of the class described, a pair of pivotally-connected side members,a bracket member connected with and extending forwardly from the pivotal bolt connecting said side members, a cross-piece adjustably connected with said bracket member and having slots at the ends thereof, angular brackets secured to and extending outwardly from the side beams, a draft-ring, and links connecting the latter with the front sides of the angular brackets, said links extending through the slots in the vertically-adjustable cross-piece.

2. In a device of the class described, a pair of side beams, castings secured upon the latter and provided with laterally-extending ears, a pivotal bolt connecting said ears.aforwardlyextending bracket member mounted upon said bolt, a cross-piece vertically adjustable upon the front end of said bracket member and having slots at the ends thereof, angular brackets secured upon and extending laterally from the side beams, a draft-ring, and links connected adj ustably with the angular brackets. extending through the slots of the cross-piece and connected with the draft-ring.

3. In a device of the class described, a pair of pivotally-connected side beams, oneof which extends in front of the other, a bracket member in the form of a bail connected with the pivotal connecting means and extending forwardly therefrom, the lower part of said bail having an opening at a distance from the pivotal point, and an earth-engaging element having a shank extending through said opening and connected with the front end of the forwardly-extending side beam.

In testimony that I claim the foregoing as my own 1 have hereto affixed my signature in the presence of two witnesses.
