COMBINED CULTIVATOR, HARROW, AND RAKE.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed October 18, 1910. Serial No. 587,770.

To all whom it may concarnh Be it known that we, ABBA BENTON and CHARLES D. JORDAN, citizens of the United States, residing at Monticello, in the county of Jasper and State of Georgia, have invented a new and useful Combined Cultivator, Harrow, and Bake, of which the following is a specification.

The invention relates to a combined cultivator, harrow and rake.

The object of the present invention is to improve the construction of combined cul tivators, harrows and rakes, more especially that shown and described in Patents Nos. 902,367 and 935,578, granted to us Oct. 27, 1908, and Sept. 28, 1909, respectively,,and to provide simple, inexpensive and efficient means for effecting a rapid adjustment of the cultivator teeth and to elfect a rigid connection between the parallel tooth carrying bars and the side braces to prevent lost motion or looseness of the parts.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a plan view of a cultivator, constructed in accordance with this invention, the parallel tooth carrying bars being disposed at right angles to the beam to arrange the cultivator teeth to form a rake. Fig. 2 is a reverse plan view of the same. Fig. 3 is a central longitudinal sectional view of the cultivator. Fig. 4 is a plan view of the cultivator, the parallel tooth carrying bars being disposed at an acute angle to the rear portion of the beam to arrange the teeth to form a cultivator. Fig. 5 is a transverse sectional view on the line 55 of Fig. 1. Fig. 6 is a detail sectional view on the line 66 of Fig. 4. Fig. 7 is a detail sectional view, illustrating the manner of pivotally connecting the harrow teeth with the rear'tooth carrying bars.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a beam, equipped at its rear end with handles 2 and at its front end with a suitable clevis 3. Extending laterally from the beam at a point intermediate of the ends thereof are adjustable front and rear tooth carrying bars 4 and 5, disposed in pairs and arranged in parallelism. The laterally extending bars are secured at their inner ends to the lower face of the beam by means of vertical pivot bolts 6 and 7, and they are connected at intervals by harrow teeth 8, fitted against the lower faces of the laterally extending bars and pivoted to the front laterally extending bars by bolts 9 and pivotally connected with the rear laterally extending bars by means of grooves 10 and protuberances 11.

The protuberances and grooves are retained in their interfitting relation with each other by means of a lower transverse bar or brace 10-, connected with the rear laterally extending bars by bolts 11*, located between the spaced teeth, as clearly shown in Fig. 2 of the drawings. The cultivator teeth have straight upper portions, and the grooves 10, which are formed in the upper faces thereof, extend longitudinally of the same and receive the protuberances 11, which are formed by indenting the rear laterally ex tending toot-h carrying bars.

The harrow teeth may be of any desired number, and the outer ends of the laterally extending tooth carrying bars are preferably connected by short'end bars 12, pivoted to the outer terminals of the laterally extending bars by bolts 13.

The adjustable laterally extending tooth carrying bars are adapted to be moved either backward or forward from the position at right angles to the beam, illustrated in Figs. 1 and 2 of the drawings, and they are secured in their adjustment by means of side longitudinal braces 14, consisting of arcuate intermediate portions and straight terminal portions, which are preferably formed integral with each other and are bolted, or otherwise secured to the beam at the lower face thereof. The curved side braces 14 are shown provided with front and rear sides of perforations 15, which are adapted to receive the fastening means, described'in the aforesaid patent. In the present invention, the front laterally extending tooth carrying bars are equipped with slides 16, consisting of a horizontal bottom portion, vertical side portions and inwardly extending top portions 17, spaced apart and engaging the upper faces of the side braces 14. The sides are provided in their bottom portions with counter-sunk perforations 18 for the reception of bolts 19, which have their heads arranged in flush relation with the upper faces of the bottom portions of'the sides. The bolts 19 pierce the front laterally extending bars and the front terminals of the straight portions of the adjacent cultivator teeth, and are equipped at their lower ends with nuts 20, engaging the lower faces of such cultivator teeth. In the adjustment of the cultivator teeth, the slides move along the arcuate portions of the curved side braces and when secured in their adjustment provide a rigid connection between the tooth carrying bars and the side braces and prevent lost motion.

The teeth are secured in their adjustment by means of straight angularly related connecting bars or braces 21, diverging forwardly and pivotally connected at their front ends to the rear tooth carrying bars by bolts 22, or other suitable fastening devices and provided at their rear portions with longitudinal slots 23, through which passes a bolt 24, having a tail nut 25 for clamping the slotted braces or connecting bars 21 in their adjustment. The bolt pierces the beam and extends through the slots of the overlapped rear portions of the adjustable bars or braces 21, and is provided at its lower end with a head, the tail nut 24 being located at the upper face of the beam to facilitate the adjustment of the parts. The, slidable connection between the front tooth carrying bars and the side braces and the slot and bolt connection between the braces 21 and the beam afford a quick adjustment of the harrow teeth and rigidly retain the same at any adjustment.

The cultivator is equipped with a top transverse brace '26, centrally secured to the upper face of the beam by the front bolt 6, and having curved laterally extending side portions,'which are secured at their outer terminals to the side braces by screws 27, or other suitable fastening devices, the ends of the transverse brace being spaced from the upper faces of the side braces by blocks 28. The spacing blocks 28 are of a width less than that of the side braces to permit the spaced inwardly extending top portions 17 of the slides to engage the upper faces of the side braces and 'to pass the spacing blocks.

The cultivator is equipped with a fender 29, constructed, arranged and operating similar to the fender shown and described in the aforesaid patent, and in Patent N 0. 895,716, granted to us Aug. 11, 1908.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is

1. The combination with a beam, of a curved side brace connected with the beam, a pivoted laterally extending tooth carrying bar, means carried by the laterally extending bar and slidable on the side brace for adjustably connecting the laterally extending bar with the brace, and adjusting means connected with the beam for securing the laterally extending bars rigidly in their adjustment.
