comprising two relatively movable/connected members adapted tobe'operatively connected with the; beams, a longitudinally-extending adjusting-lever sustained by one of the members, a connection between said lever and the other-membenand means carried by the lever for locking the members in fixed relations, said lockingimeans being independent of the connection between the lever and said other member. 2. In combination with the beams, acounectingeyoke therefor comprising two relatively movable connected members operatively joined with the beams, an adjustinglever sustained wholly by one of said mem-' bers and extending longitudinally therefrom rearward, a connection betwe'en the lever and the other member, and a lockin device jcarriedby the lever and adapted to old the iinemberslof the arch in fixed relations, said locking device being independent of the connection of the lever with said other member.

.3. Incombination with the beams, a yoke.

operatively connected therewith, and comprising two relatively movable connected i355 ,l tween the lever and the other member, and amembers, an adjusting-lever carried wholly by one of the members and extending rear ward longitudinally, a link connection be locking device carried 'by the lever for lockthe members in fixed relation, said lockdevice being independent of said link connection,

4.A connecting-yoke comprising two relatively movable connected ,members adapted to: be operatively connected with the beam,

in combination with an adjusting-lever sustained by one of the members, a slide on said member, a ointed connection between the slide and the lever, anda jointed connection between the slide and the other-member.

5. A connecting-yoke for cultivator-bea1ns ada ted t0 be operatively connected therewitli comprising two relatively movable members jointed together and adapted for angular adjustment, in combination with a slide on one of said members, a'link jointed at one end to the slide and at its other end to the other member, and means for adjusting said slide.

6. A connecting-yoke comprisingtwo relabination with an adjusting-lover'sustained by one of said members, a slide also mounted on said member, a link 'oining the lever to the slide, and a second link PIVOtGd to the slide and to the other member.

7 A connecting-yoke, comprising two rela-' tively movable connected members, a segtively movable connected members, in comfixed to the upper end of one 0 said members and extending longitudinally rearward and formed withlocking-teeth, an adjusting-i lever pivoted to the side of said segmentplate and extending longitudinally rearward,

a locking-dog carried by the lever and adapted to cooperate with the teeth, a slide mounted on the member carrying the segmentplate, a link connecting the lever with said slide, and a second link connecting the slide with the other member.

In testimony whereof I -hereunto set my hand this 28th day of November, 1905, in the presence of two attesting witnesses.
