IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 20,207, dated May 11, 1858.

To all whom it may concern:

Be it known that I, L.W. KELLEY, ofBrunswick,in the coun ty of Medina and State ofOhio, have invented a new and Improved Cultivator; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, makin g part of this specification- Figure 1 being a side elevation of the cultivator; Fig.2, a plan thereof; Fig. 3, arearelevation of the same.

Like letters designate corresponding parts in all the figures.

Iemployacentral beam,A,ofsuitablelength, to which the other parts are secured. First, the handles 0 O are attached to it at their forward ends by a bolt, m, and are supported behind by a stretcher-bolt, a, passing through a supporting-standard, D, which extends upward from said beam A. A central cultivator-tooth, H, is also secured directly in this beam, and, if desired, for some uses another toot-h, K, may be also added near the rear end thereof. What other teeth, I I, are used are secured in side beams, B B, which are connected with the central beam at their front ends by means of transverse hinge bars or plates E E, secured to the central beam by a vertical bolt, a, and to the ends of these side beams respectively by bolts 12 b, which serve as hinge-pivots, whereon the beams may turn in moving outward or inward. Curved bars or plates G G, in form and position nearly concentric with these pivots of the side beams, are secured at their outer ends to the rear ends of said beams by bolts 0 c, and

- they are provided respectively with sets of holes at d at corresponding and regular distances apart, by which both bars are secured to the central beam by inserting a single'bolt, at, through two of those corresponding holes and the said beam together. Thus by bring ing different holes d d centrally over the beam A the hind ends of the side beams, B B, are adjusted outward or inward at pleasure. Besides, two wing-scra-pers, M M, are secured to the central beam by means of a bar, L, extending downward and forward obliquely through the beam, and as low as the bottoms of the scrapers, and the scrapers are secured to said bar by bolts or rivets Z ll, driven transversely through both the scrapers and the bar. The

scrapers meet in front of the bar in a sharp edge, except near the lower end thereof, where said bar extends forward beyond the scrapers and terminates in asuitable point, N. The bar itself may be secured in its beam-mortise by means of a wedge, h, and pin 6, or their equivalents. The scrapers spread outward and backward symmetrically, and their lower or scrapin g edges may have any desirable form. They are made of spring-steel and quite thin, so that they may be beutinward toward each other and outward from each other, if desired, although it may be most suitable to so secure them to the bar L that they will, in their natural positions, be spread as widely apart as their use may ever require. Near their rear ends and to their inner sides are respectively secured horizontal curved bars or plates G G, concentrio in curve and position with the front ends of the scrapers, or with the bend thereof. These bars lap by each other and project inward just beneath the central beam, A, to which they are both secured by a single bolt, f, passing upward through uniform and correspoudingholes, g g, in the respective bars and through said beam in a manner similar to that for adjusting the bars G G, above described. By this means the scrapers may be adjusted inward or out ward at pleasure; and ifsaid scrapers are only bent inward the resistance of the ground to their movement will be sustained by the spring of these scrapers, thus ofiering no strain upon the bars G G, which, therefore, require to be merely strong and firm enough to keep said scrapers bent.

The bars E E, G G, G G, and L are so secured to the central beam, A, that they can be with facility disconnected therefrom, to enable the full purpose of the cultivator to be readily availed of. This purpose of the implement, as above described, is to make it convertible into three dilferent kinds of cultivators, each complete in itself and capable of the desired adjustability. They are specified as follows: First, the complete implement, as above described, is a scraping and tooth cultivator combined, and the scrapers are adjustable separately from the adjustment of the teeth, or the teeth are adjustable separately from the ad justment of the scrapers, or both are adjustable together uniformly or not, for by extending outward or Contracting inward the adjusting-bars G G the side beams and their teeth I I are adjusted outward or inward independently of the scrapers, and by similarly extending or contracting the bars G G the scrapers to and d, by which the side beams, B B, with their adjuncts, are removed, and taking out the tooth H from the central beam; finally, a simple" tooth-cultivator, equally complete, compact, and adjustable, is just as readily formed by simply removing the bolt f and wedge h and pin 2', (if both areused,) and thereby detaching the scrapers M M and their appendages from the central beam.

What I claim as my invention, and desire to 'secure by Letters Patent, is-- The combination and arrangement of the teeth-beams B B with their attaching and adjusting bars E E and G G, and the scrapers M M, with their attaching and adjusting bars L and G G, with each other and with the central beam, A, substantially in the manner and for the purposes herein set forth.

In witness that the above is a true specification of my improved cultivator I hereunto set my hand this 3d day of March, 1858.

L. W. KELLEY.
