ROTARY-MOLD-BOARD PLOW.`

SPECIFICATION forming part of Letters Patent No. 5326,030, dated September 8, 1885. Application iiled January 2, 1885. (No model.)

To allwhom it may concern:

Be it known that I, EZRA G. GODDARD, of East Saginaw, in the county of Saginaw and State of Michigan, having invented new and useful Improvement-s in Rotary-Mold-Board Flows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which forni a part of this specification.

This invention relates to certain new and novel improvements in the construction of plows.

The invention consists in the peculiar combinations and the construction and arrangement of parts,` hereinafter more fully described and claimed.

Figure 1 is a perspective of my improved plow. Fig. 2 is a top plan, and Fig. 3 is a vertical crosslsection through the axis of the disk. v

In the accompanying drawings, which form a part of this specification, A represents the landside of my improved plow, which is provided with the plow-point B and share O, the

' heel ofthe share being connected to the landside by the brace D.

E represents the plow-beam, -l--shaped in cross-sections, the rear end of which is secured tothe upper edge of the landside,while its forward end is provided with the ordinary clevis attachments. This beam is provided with a rearwardly-projecting arm, F, leaving a recess between said beam and arm, said recess eX- tending beyond the longitudinal cent-er of said beam, as shown in Figs. 1 and 2. In theend of said arm is suitably secured one en'd of a stationary shaft, G, upon which the `rolling disk I-I is journaled, the opposite end ofthe shaft being secured to the main portion of the beam, so that said shaft is diagonal to the travel of the plow. I are the handles.` This disk H may be either concave or fiat upon its mold-board face, and is sufficiently large so that its periphery will form a continuation of the cutting-edge of the share and point. It

will also be observed that a portion of the disk is hid behind the upper'and inner edge ofthe Share.

The disk is set at a suitable angle to the line of draft, so that in plowing the slice cut, in

coming in contact with the disk, will compel the disk to rotate, and thereby very materially lessen the friction and lighten the draft. As the disk forms a continuation of the cutting-edge of the point and share, it will in its rotation cut the sod and free itselt' from material that would tend to clog beneath the beam. While I have shown the beam as lcurved horizontally beyond the landside, it is evident i that it may bearched vertically and have the disk rotate beneath it without departing from the spirit of my invention.

I am aware of the PatentsN os. 7 7,184 and 114,002, and make no claim to the constructions shown therein as forming part of my inl vention.

What I claim as my invention is I 1. In a plow, the beam E, provided with th rearwardly-projecting arm F, formed integral therewith, said beam and arm being construct! ed as shown, whereby a recess is left between the two, said recess extending forward beyond the longitudinal center of said beam, substantially as described.

2. In a plow, the beam E, -f--shaped in crosssection and provided with a bend, as shown, and with the rearwardly-projectingarm F, formed integral therewith, leaving a recess between said beam and arm, said recess extending forward beyond the longitudinal center of said beam, and said beam and arm enlarged to receive the shaft G, in combination with said shaft G, and the disk H, carriedby said shaft and revolving in said recess, substantially as and for the purpose specified.
