I IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 167,756, dated September 14, 1875; application filed September 3, 1875.

To all whom it may concern Be it known that I, IRVIN FREEMAN, of Corpus Christi, in the county of Nueces and 7 State of Texas, have invented a new and Improved Plow; and I do hereby declare that following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure 1 is a side elevation, partly in section; Fig. 2, a bottom view of share and moldboard Fig. 3, a detail view of shovel-plow.

Theinvention is an improvement in the class of plows whose shares or shovels are secured by means of a hook-rod passing through the beam. The improvement relates particularly to the construction and arrangement of parts, whereby the mold-board and share are locked together, and the skeleton or standard secured to the beam by means of such hook-rod, all as hereinafter described. 4 r

A represents the beam, B the skeleton, O the share, and D the mold-board, of a plow. The moldboard has a rigid subjacent part or attachment, D, projecting below the lower end, and provided with the slot d. d is a re cess in the upper end of part D to receive the lip I) of frame, in order to preventthe moldboard from moving upwardly, while d is a lip of mold-board that fits into a recess, 0, of share. The share has also a subjacent part or attachment, 0, that fits into slot 61 and in which is made a hole, 0 to receive the hook e of the long rod E. The latter extends up obliquely under the mold-board D, through the skeleton B at b 11 and also through the rear end of beam, so as to receive on its threaded end the lever-nut F. The mold-board being thus jointed at b d to the frame, and at c d to the share, the hook e is placed in the hole 0 and thelever-nut turned one or more times to'secure the parts firmly together, while the rod E also serves as a re-enforcementto the whole. The arrangement of the hook-rod to pass through the rear portion of the skeleton B enables me to dispense with the bolt ordinarily employed to clamp or secure a skeleton to the rear end of a plow-beam. The top-slotted lug Gr, having head g, may be placed through a slot of ton, and securing it to the beam, in the man ner specified.
