IMPROVEMENT IN CUL'l'lVATORS.

Specification forming part of Letters Patent No. 175,636, dated Apr l 4, 1876; application filed December 23, 1875.

To all whom it may concern:

Be it known that I, JOHN A. ADAMS, of Battle Creek, in the county of Calhoun and in the State of Michigan, have invented certain new and useful Improvements in Cultivators; and do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangement of a cultivator, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appert-ains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a plan view of my cultivator.

I Fig. 2 is a side elevation, and Fig. 3 is a section of the same through the line 00 m, Fig. 1. Fig. etis an enlarged perspective view, showing the construction of the cultivator-teeth.

A represents the main frame of my cultivator, provided at each end with a plate or casting, B, extending from the front rear ward for a suitable distance, and extended upward at its rear end, which extended portion is formed with a curved slot, a.

On each end of the frame at the front of the casting B is pivoted a lever, (J, which carries the spindle b, for the wheel E placed thereon. The inner end of this spindle passes through the slot at in the casting B, and has a head or its equivalent on its end on the inner side of said casting, to hold the same thereto.

'By means of these side levers G O, the frame A may be regulated at varying distances from the ground, as required, for making the cultivator-teeth run'deep or shallow,

the levers being held by ordinary ratchet devices.

On the front side of the frame A, near each end, is secured a brace, D, which extends forward and inward, and is arched as shown in Fig. 2. The front ends of these braces are fastened to the sides of the tongue G by a single bolt passing through them, so as to pivot the tongue between them.

The tongue Gr extends rearward over the main frame A, and has a frame, H, secured to its under side, to which latter frame the cultivator-teeth are attached. The rear portion of the frame H is, by chains 01 01, connected with arms 6 e projecting from a shaft, j, which has its hearings in standards I I on the rear portion of themain frame A. On one end of the shaft f is a semicircular 1ever, J, for raising and lowering the frame H, which lever may be operated either from the drivers seat It or from the rear of the machine, if the driver is Walking behind.

It will thus be seen that the cultivatorframes are attached to the tongue far forward by the single bolt i, on which latter it is free to play as a pivot or hinge in such a manner that the frames may have free play up or down or laterally, oscillating, so to speak, in order to allow the cultivator-teeth to raise over or pass around stones or other obstructions without unnecessary strain upon the team or the different parts of the cultivator, thus obviating a very serious cause of breakage thereof. Either end of the plowframe is free to lift up without lifting the plows on its opposite end out of the ground, and they work or move laterally when meeting with such obstructions.

K K represent the cultivator-teeth or plows, each of which is fastened to the lower connected ends of two bars, L and L, forming the plow foot or shank.

The upper end of the front bar L is bent forward and fastened to the under side of one of the cross-bars of the frame H, with the angle against thefront side of one of thelongitudinal bars of said frame. On this longitudinal bar'is secured a plate or casting, h, the front of which is slotted or grooved to straddle the bar L from behind and hold it firm, free from any lateral or side motion. The upper end of the bar L is bent rearward and fastened to the same cross-bar of the frame H.

By these means greater strength and efficiency are secured to the Whole machine, preventing splitting of the plowframe.

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

1. The combination of the stationary main frameA, braces D D, tongue G, pivot-bolt i, In testimony that I claim the foregoing I and movable cultivator-frame H, 2111 substztnhave hereunto set my hand this 30th day of tially as and for the purposes herein set forth. November, 1875.

2. The notched guide-plate h attached to the JOHN A. ADAMS. under side of the frame H, in combination Witnesses: with the bars L and L, as and for the pur- JOHN MEAGHEM,-

poses herein set forth. WILLIAM A. BRIGGS.
