. j IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. I 83,393, dated October 17,1876; application filed July 10,1876.

To all whom it may concern:

Be it known that I, GEORGE T. Hnnig'icK, of Mill Springs, in the county of Wayne and State of Kentucky, have invented a new and Improved Plow and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention is an improvement in the class of sod or turning plows and relates, first, to the construction of the stock, wherebyit is adapted for attachment of right and left shares and mold boards; second, to the construction of said shares and mold boards, whereby they are adapted for such attachment; and, third, to the provision of an adjustable wheel, which is so attached to the heel of the plow as to adapttit to be swung under the latter to support it while being drawn or propelled from one place or field to another.

In the accompanying drawing, forming part of this specification, Figure 1 is a side elevation of the plow, with a part in section. Fig. 2 is a plan View of the under side of the plow proper. Fig. 3 is a front view of the double share and mold-board. Fig. 4 is a vertical section on line a: m, Fig. 3. Fig. 5 represents different views of the L-shaped brace. Fig. 6 represents the T-shaped brace. Figs. 7 and 8 are detail views of plow-stock.

Apart from the beam and handles A B B, the frame of the plow consists, mainly, of the curved flat standard 0, extended forward and terminating in a triangular point, a, and the land-side plates D, which are attached to the rear extension I) of the standard by means of bolts or other suitable devices. The standard 0 has a number of bolt-holes and a lug, d, the latter being located on one side, immediately in front of the end of a land-side plate, D. These said holes, the lug, and the point a of the standard, together with the shoulders or bearing-surfaces formed by the ends of the land-side plates, constitute the chief features of the construction of the stock, whereby the share and mold-board are firmly but removably attached, as will presently appear. The share and mold-board may be constructed double, as shown in Figs. 3 and 4', to adapt them for reversal, as required for hill-side plowing, or the same may be of the ordinary form,

as shown in Fig. 2, and made either right or left. In either case the construction of the parts whereby the attachment to thestock of the plow is effected is substantially the same that is to say, a plate, E, is attached to the under side of the share and mold-board, and serves to connect one to the other. This plate has a vertical flange or wing, c, which is notched on the rear side to receive the lugd of the standard 0. The flange 6 lies parallel to the vertical barf formed on the inner side of the share or point. 7

When the share and mold-board are applied to the stock, as shown in Figs. 1 and 2, point a of the standard 0 enters between the flange e of plate E and the bar f of the share, and a bolt is passed transversely through them all, to lock them securely together. The vertical rear sides 'or edges of said flange and bar likewise abut the ends of the land-side plates B, while the lower edge of the remaining bar or flange rests upon the upper edge of the inner one of said plates B, and is similarly secured to the standard 0 by means of bolts. By this construction the share and mold-board are securely attached to the stock, but may be conveniently and quickly removed and readjusted or substituted by others, as occasion requires.

The brace F- for supporting the mold-board has an .L or T shaped head, according as it is required for use in connection with the single right or left share, Figs. 1 and 2, or the double share, Figs. 3 and 4. In either case the lug or arm 2' which forms the head enters a socket formed between the land-side plates, and no bolt or other supplimentary fastening is required to secure it in place. The brace is hence adapted to be readily detached or adjusted in position on either side of the plow. The colter H has a horizontal shank, I, through which passes the bolt that secures it to the standard 0, and the lower end of the colter rests against the share and mold-board, so as to be supported by them while cutting the sod. By this mode of constructing and attaching the colter some material is saved, and the colter is less liable to be broken than when attached to the beam. The wheel I, by which the entire plow is supported when being drawn or propelled from one point or thus assists to hold the arm K steady. When i. i

the Wheel is not required for useyth'e'armis swung up in a position nearly parallel to the handles, between which the wheel passes and is securedby a hook,-m*, as"s=h-own.=

This device is applicable to various kinds of plows, and may be pivoted to other parts of the plow than the heel of the land-side.

I do not'claim; broadly; theattachmentof a baringwhc'el toa plow in such manner as to 1 adapt it to swing under and support What I claim is-' 1. The plow-standard O,=havingthe point a and lug d, and-provided with the seat hav-" ing the notched vertical flang e as shown andtdescri'liedi y 22 The combinationof thestandard ()with double land side, mold-board, and share, as

"shown and described.

3. The curved or bent arm K, carrying the bearing-wheel and pivoted tothe land side plates, as shown and described, for the purposespecified..

4. The bent arm pivoted tothe heel of the land-side, the bearing-wheel, pivoted to the free end of said arm, the hook m, and the liaudlesB; extended below thebeam; as shown iand idescribed, whereby the wheel may be secured in the elevated position, as specified. 1
