In a wing sweep attachment for plows a continuous ring having its front portion inclined and extended upward and its rear or body portion slotted to receive the sweeps, the exterior face of the body por- 30 tion being vertically ribbed in combination with a sweep having a shank detachably locked to the slotted body of the ring and a washer having its inner face vertically ribbed, said washer arranged on the shank 35 of the sweep adjacent to the outer ribbed face of the ring and interlocking with said ribbed face combined with means for ad- justably attaching the upwardly extending front portion of the ring to the standard of 40 the plow. In testimony whereof I have signed my name to this specification. M. T. SKINNER. each, by addressing the "Commissioner of Patents. on, D. C."
