CU LTIVATORA OR HARROW.

SPECIFICATION forming part of Letters lfatentl Nor 692,830, dated February 11, 1902. l

Application filed June 22,1901. Serial No. 65,685. (No model.)

To all whom t may concern: I

Be it known that I, MARoELLERs COLLINS, a citizen of the United States, residing at Sturgis, in the county of Oktibbeha and State of Mississippi, have invented a new and useful Cultivator or Harrow, of which the following is a specification.

This invention is an improved construction of cultivator, the object being tov provide a highly practical and exceedingly simple construction of cultivator susceptible to a multiplicity of adjustments. L

With this object in view the invention consists in thevpeculiar `construction of the various parts and in their novel combination and arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this specification, Figure l is a perspective View, one of the handles being broken away adjacent to the forward end for the purpose of more clearly illustrating the centrally-slotted reinforcing-bar through which the central beam 2 is a top plan view. 'Fig. 3 is a side elevation, and Fig. 4 is a detail sec- -tion on the line 4 4 of Fig. 2.

In carrying out my invention I employ a main frame comprising side beams A and A' and the arched standard B, connected at its lower end to the said side beams A and A', said arched beam B havinga horizontal bracebar connecting the side members and arranged parallel with the upper member of the arched standard. The forward portions of the side beams A and A are the extreme forward ends of the said beam. The handles D are also connected to the said beams, said handles extending upwardly and rearwardly, as shown, and are connected to the side members of the arched standard, as

securely fas tened together, and a clevis C is connected to in Fig. 2. beams A and A are braced orv reinforced by means ota bar E, angular or bow-shapedin general contour, the side members being securel y bolted to the'beams A and A', as most clearly shown,'the central or intermediate portion E of the said bar extending across theangle between the said bars A and A a short vdistance to the rear of the point whereV ksaid-beams meet, and it will be noted that this central or intermediate portion is en- 'Ihe .div-erging portionsof the l larged and slotted vertically, as shownat E2.l

A central beam F is pivoted at its forward end between thebeams A and A just before they begin to diverge, and it will be noted that the said beam F passes through the slot E2 in the central portion E of the brace or reinforcing bar The bar F extends upwardly and rearwardly and is'fastened to a depending bar G, Which hangs down centrally of the brace-bar B'. The beam YF is then curved downwardly to provide a standard for thecultivator tooth yor point F.

A `double tooth-bar H is securely fastened between the main portion of the side beam A and the end of the beam A', said tooth-bar being arranged at an oblique angle to the line of draft. The forward faces of the members l`of this tooth-bar are notched, as shown at H',

to receive the Shanks I of the cultivator-teeth I', eyebolts K being arranged between the members of the tooth-bar, the shanks of the cultivator-teeth passing through the eye, the threaded portions of said eyebolts passing through plates L, arranged upon the rear of the tooth-bar H, nutsA L' being employed to securely fasten all of the said parts together. By means of this construction the cultivatorteeth can be adjusted to-any height-desired, and they'can also be shifted laterally whenever necessary. l

By constructing the frame in themanner hereinY shown and described an exceedingly light and rigid structure is obtained, and in addition tothe adjustments ofthe cultivatorteeth in connection with the tooth=bar I am also enabled to adjust the central tooth carried by the central beam. Y y

Having thus fully describedy my invention, what Iclaim as new, and desire to secure by Letters Patent, is- 1. In a cultivator, the combination with the side beams and arched standard, of the handles connecting the forward portions of the side beams and the arched standard, and the tooth-bar secured to the diverging portions of the side beams and the vertically-adjustable central beam, all arranged substantially as described.

2. lu a enltivator, the combination with the side beams connected at their forward ends and diverging rearwardly, the extreme ends of the side beams being bent toward each other, of the arched standard connecting the end of one beam to the intermediate portion of the otherbeam, and a tooth-bar connecting the intermediate portion of the first-named beam and the end port-ion of the second-mentioned beam, substantially as shown and described.

The combination with the side beams connected at their forward ends and diverging rearwardly, the arch-shaped standard connecting ihc Lside beams, the reinforcing or arch-shaped standard connecting said beams, L

the brace-bar attached to the said standard and having a depending hanger, a brace or reinforcing bar slotted centrally, and the ccntral beam pivoted between the side beams, Working through the slot of the brace-bar and attached to the depending hanger, snbstan tially as described.

MARCELLERS COLTJNS.
