IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 118,053, dated August 15, 1871.

l'o all whom t may concern:

Be it known that I, EDWIN REESE, of Ent-aw, in the county of Greene and State of Alaba-ma, have invented a new and useful Improvement in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the saine, reference being had to the accompanying drawing making a part ot' this specification, in which- Figure 1 is a top view. Fig. 2 is a side elevation with one ofthe transportin g-wheels removed, and Fig. 3 is a rear elevation.

This iinf'ention relates toa wheel-cultivator, in which the shovels are attached to a frame placedl beneath the main frame; and the invention consists in the arrangement ofsaid lower frame, rockshaft, lever, draft-chains, and whiftletree, whereby certa-in advantages are secured in the operation ofthe cultivator. These parts or devices are hereinafter fully described in connection with others forming a complete or operativemachine.

Referring to the drawing, the frame to which the shovels are attached consists oID two plowbeams, a, connected at their rear ends by a crosspiece, l), and at their iront ends by a metal bow, c, which has feet, d, projecting horizontally outward from each branch of the bow, to which feet the pl ow-bea ms a are fastened by bolts. Said feethave each a number of orifices made vertically through them, through either of which the connecting-bolt may pass, which arrangement allows the front ends of the plow-bea-ms to be swung outward or inward so as to set them as near to or as far from the rows as desired. Ais the main frame. The transportin g-wheels B are mounted on short axles C which are secured to the cross-bar D of the main frame by means of staples cl which arrangement enables the axles to be slid in or out so as to adapt them to rows that are different distances apart. E is a rock-shaft whose journals enter holes made through lugs e that project upward from the sides of the frame A, several such holes being made in each lug in order that the said rock-shaftmay be placed higher or lower so as to suit the land or plows. A lever, j', is pivoted to the upper side of the shaft E, so as to swing horizontally. The front end of the lever j' is fastened to the top of the bow c. By turning the shaft E the plow-beams a may be raised or lowered at pleasure, and by swinging the lever f laterally the front ends of the plow-beams may be shifted to either side so as to cause said plowbeams to follow or not the draft-animals when the latter change direction. The front ends ot' the beams a are connected by chains gwith the extremities of a whiftletree, hf, that is pivoted to the lower side ofthe tongue F, which whiffletree and chains are, therefore, the devices that communicate the motion of the tongue to the plowbeams. Vhen the team turns to one side the whiflietree IL swings to an angle with the tongue, and consequently prevents a greater st ain bein brought upon one chain than the other. The cha-ins q are connected by cross-chains i with the tongue, and the nearer to the tongue the points in the said cross-chains are at which the latter' are hooked to the chains g the more upward is the draft of the chainsy upon the plow-beams a. By taking up, therefore, or lettingI out lthe chains z' the depth to which the plows run is regulated. By attaching the hook la in the cross-piece b to an eye, I, in the lever f, the plow-beams are held suspended clear ofthe ground for transportation to and fro. rEhe bow c being attached to the beams c at some distance in front of the shovels, the operatoris enabled to either swing the shovels side wise or raise them considerably easier, by reason ofthe leverage,than as thou gh th e bow were attached directly above the shovels. This arrangement of the lever, draft-chains, &c., enables the frame a to be shifted laterally, and raised or depressed simultaneously, while the draft-tension of the chains remains the saine under all the varying positions lassumed by said frame.

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

The arrangement ofthe shovel-frame a, bar or bow c, lever f, rock-shaft E, chains g g, and whiflietree h with the frameA and tongue F, as shown and described, to operate as specified.

EDWIN REESE.
