IMPROVEMENT IN CULTIVATORS.

Specification forming fait of Letters Patent No. 153,404, dated July 21,1874; application filed March 17, 1874.

To all whom 'it may concern Be it known that we, GEORGE lV. VAN SICKLE and CALVIN McGoNAUGHY, of 'Burlington, in the county ot' Des Moines and State of Iowa, have invented a new and Improved Oultivator; and that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, a-nd to the letters ot reference marked thereon, making a part of this specification.

The invention consists in a cultivator provided with an anti-frietion coupling for securing the beams to the axle, and also the combination, in a cultivator, of the frictioncouplin gs, beams, and arched axle.

In the accompanying sheet ot' drawings, Figure l is a side elevation of our invention, and Fig. 2 a plan or top view of same.

Similar letters of reference indicate like parts in the several gures.

A A represent the beams of a cultivator, to the under sides of which are affixed the plows B B. These plows are secured to the beams by bolts at their upper ends, and they are braced by curved braces O C extending from the shank of the plows to the beam. Aftixed to the front end of each beam is a plate, D. Passing through the center of the plate D is a pivotal bolt, a. The lower part of this bolt passes into and is secured to a shaft, E. Onto the shaft E are fitted two rollers, F F, in such manner that as said shaft E turns on the bolt a the rollers F F will freely turn against the upper side of the plate D. Firmly bolted or otherwise secured to the axle G are two plates, H H, these plates, bearing upon the under side of the rollers F F. The axle G between the plates H H is bent upward in the shape of an inverted U. Aftixed to the upper side of this axe is the tongue I. This tongue is so attached as to readily oscillate thereon. At or near the end of that part of the tongue I which extends back of the bent part of the axle, is affixed or secured a pulleywheel, l), and to the front end of the tongue or pole I is bolted an evener, J. Projecting below the under side ot" the evener, at its ends, are two projections, o. These projections are firmly secured to the evener by braces or otherwise. Pivoted or otherwise secured, so

as to turn freely on the lower ends ot' the projections c, are two connecting-rods, K, having hooks d on their lower ends, the upper ends of these rods being attached to a cord or chain, e, which passes around the pulleywheel b. On the upper surface or top of the tongue I are secured two line-holders,f, formguides for the reins.

Our cultivator being constructed substaneially as above described, its operation is as follows: Horses being attached to the end ot' the pole or tongue I, the cultivator is drawn over the surface of the ground in the ordinary way, the beams A being allowed to freely ad` just themselves to every change ot' direction without permitting the beams to rock or the plows to vibrate, and the change of direction ofthe beams is effected with the utmost ease, and no amount of use or wear can cause the beams to work loose at the point or joint which attaches them to the axle, for the reason that the weight of the beams and strain is borne by the friction-rollers F F, in the manner before described. The sin gle-trees are hooked into the hooks d at the end of the connecting-rods K, so that it' one horse of the team shall pull ahead of the other the pulley b will yield to the action of the cord e, preventing one plow from being pulled ahead ot' the other or out of line, and will also prevent the end ot' the tongue from being forced against the other horse. The construction ot the evener J, in connection with the projecting-rods c and connecting-rods K, is of very great value, for the reason that as the team is pulling there is a downward draft in the rear of the axle, and an upward draft in front of it, keeping the tongue I at all times in a balanced position-the result being that all or nearly all the weight is taken from the necks of the horses, and it is borne by the inverted-U support of the tongue. The braces O G are curvilinear in form, so that as sticks, reeds, and other material shall meet them, as the cultivator progresses, they will not remainin front of the plows to obstruct their action, for, the braces being curved, no sharp angle is formed to act as a catch, but wha-tever refuse shall come in contact with the curved braces will quickly be displaced therefrom, leaving the plows free from obstruction.

curing the beams to the axle, composed of the plates for embracing the axle and the frictionrollers attached to the beams and working on said plates, substantially as' shown and described.

2. In a cultivator, the combination of friction-couplings D F H, beams A, and arched axle Gr, substantially as and for the purpose described.
