UNrrED STATES PATENT GEEICE.

OLE JAOOBSON GLASOE, OF LANESBOROUG-H, MINNESOTA.

IMPRovi-:MENT IN PLows.

Specitication forming part of Letters Patent No. 164,727., dated June 22, 1875; application filed March 25, 1875.

To all whom it may concern:

Beit known that I, OLE J. GLAsoE, of Lanesborough, in the county of Fillmore and State of Minnesota, have invented certain new and useful Improvements in Piows; and I do hereby declare that the following is a full, clear, and exact description thereof, which willenable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanyii'ig drawings and to the letters of reference marked theron, which form a part of this specification.

My invention consists inthe combination, with a plow, of a device for preventing the straw from piling` up under the beam, as hereinafter more fully described, and pointed out in the cla-ims. Y

Figure l is a side View of my improved Y plow, and Fig'. 2 is a rear view ofthe same.

Similar letters of reference indicate corresponding parts in bothgures.

A is the beam, B represents the handles, and O is the share. D is a wheel or circular disk, made of iron, steel, or any other suitable material, and pivoted obliquely upon the arm a, forming part of the frame of the plow, back of the share, and mold-board. E is an endless chain or band, moving round the anged pulleys IL` and e, and provided With the clearers or cutters f. I prefer to have one or both of the pulleys 7L c provided with laterally-projecting teeth, `(shown at e in Fig. 2,) which engage with the links ot' which the chain E is composed. The pulley bis operated by the vertical shaft d and pinion g, which latter engages with the teeth or cogs 7L, arranged concentrically upon the wheel D, as shown. It'follows that when the wheel D rotates from operating the plow, the pinion g, shaft d, and pulley li will rotate also, and

the chain `E, with its clearers, will move inf that are apt to pile up under the beam, thereby greatlyimpeding progress and causing a great waste ot' power, are cut and cleared away, and my improved plow, which has in addition the benefit of the rotating land-side, may be operated much easier, and with less expenditure ot' force, than plews as ordinarily constructed Without this improvement.

Having thus described myinvention, Iclaim, and desire to secure by Letters Patent of the United States- 1. In a plow, the endless chain or band E, provided with the clearers j', substantially as and for the purpose set forth.

2. The combination ot' the wheel or disk D, having the concentrically-arranged cogs h, with the pinion g, shaft d, pulleys b c, and chain E, having cutters F, substantiallyas and for the purpose set fort-l1.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

OLE JAOOBSON GLASOE.
