1'0 (7, whom, it may concern:

Be it known that we, LUTHER E. LANnIs and WILLIAM S. MYERS, citizens-of the United States, residing at York, in the county of York and State of Pennsylvania, have invented a which the followin is a specification. This invention re ates to plow attachments and it has among its objects to present an attachment of simple and inexpensive construction whereby the plow may be guided,whereby the plow maybe gaged to enter intothe ground to various depths, which shall be useful in correcting any tendency to side draft,

and which shall also be useful in assisting the turning of the plow at the ends .of the furrows.

plify and improve the construction and operation of this class of devices.

e and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural detailstherein exhibited, but that the right is reserved to any changes, alterations, and modifications to. which recourse may be had within the scope of the invention and without departing from the spirit or sacrificing the efficiency of the same.

In said drawings, Figure 1 is a sideelevation of a plow equipped with the improved attachment. Fig. 2 is a transverse sectional view, enlarged, taken on the plane indicated by the line 2 2 in Fig. 1. Fig. 3 is a sectional Corresponding parts inthe several figures are indicated throughout by similar characters of reference. A

In the drawings the invention has been shown as applied to a plow of ordinary construction, including the beam 1, standard 2,

carrying the moldboard 3 and landside 4, and a colter 5, preceding the standard. It is to be understood that the invention 1SfIl0l3b y any means confined to this type of a plow, but that it may be applied to almost any modern I turning-plow.

Upon the sides of the beam, near the front end of thelatter, are secured, by means of transverse clamping-bolts 6, a pair of plates 7 and 8, having boxes or bearings 9 and 10 for a pair of shafts 11 and 12, both of which are slightly inclined ina downward and forward direction and normally slidable as well as r0- tatable in their bearings. Upon the upper new and useful Plow Attachment, of

Further objects of the invention are to simfora small wheel 25,

perforated for the passage of mg bolts 15, whereby which are provided with in'-' end of the'shaft 12.is fitted a clamping device provided at their upper ends with cap-pieces or lugs 17, the inner portions of which extend to form stops 18, adapted to rest upon the upper extremity of the shaft 12. Betweenthe lugs 17 is pivoted a link 19, the upper end of which is pivoted in the bifurcated front end of a lever-20, which is fulcrumed'uponan upright 21, rising from'thebeam and provided with a stop member. adapted to engage a rack-bar22, whereby the lever and its related parts may be retained in adjusted position,the handle end 23 of said lever being conveniently accessible to the operator.

The lower end of the shaft 12, which is pref'- erably constructed of steel erally in an outward tion of a headed plug tubing, is bent latdirection for. the recep.- 24, serving as a spindle constituting the land wheel or gage-wheel. The plug 24 is secured in position by means of a set-screw26, extending through the tubular shaft 12 and through a reinforcing-sleeve 27 upon the latter.

To the lower end of the shaft 1 1 thereis at- ,tached a T 28, the lower portion of which affords a bearing for a tubular shaft 29, upon which a furrow-wheel 30 is supported for rotation by means of a headed plug 31, which is secured by means of a set-screw 32, passing through a sleeve 33. j The operation and advantages of this invention will bereadily understood fi'om the foregoing description, taken .in connection with the drawings hereto annexed. 'The land-wheel is adjustable by means of the lever 20, whereby it may be retained at various adjustments to regulate the gage of the plow or the extent towhich it shall be permit- .ted to enter into the 'served that the shaft 12 is supported for oscillation with relation to the operating-lever 20 by means of a clamping device, which has been herein described. 11 other words, by

loosening the clamping device the shaft 12 may be oscillated, thus causing the gagewheel to be presented in various positions with-relationto the line of draft. 1 Thus if there should be any tendency to side draft rows of various depths, said furrow-wheel bethis may be readily corrected by twisting the l land-Wheel to the right or to the left, as may be required, and securing it at the desired adjustment by tightening the clamping device upon the shaft 12, whereby said shaft is connected with the operating-lever. g

The shaft 1 1, carrying the furrowwheel, plays freely in its box or bearing, thus imparting to said wheel-automatic vertical adjustrnent, whereby it will adapt itself to furing also laterally adjustable byzmoving the shaft 29 longitudinally of its bearings, Where it may be secured in adjusted position, as by means of set-screws 34. The general construction of the attachment is extremely simple, and it may be easily applied to any plow oflordinary construction with satisfactory resu ts.

The inclined boxes or bearings in which the shafts 11 and 12 are supported do not interfere with the free movement of said shafts to an objectionable or injurious extent; but they do serve to somewhat restrain or retard the movement of said shafts, so that they will not be readily displaced from their proper operative positions.

Having thus described the invention, what is claimed is 1. In an attachment for plows, a plate having an inclined box or bearing, a shaft supported for partial rotation and for slidable movement in said bearing, means for effect ing vertical adjustment of the shaft, and means for securing the latter against rotation.

2. A plow attachment including inclined supports or bearings, shafts slidable and rota table in said bearings, lever means for adjusting one of said shafts, means for securing the lever adjusted shaft against rotation, a landwheel carried by said shaft and a furrowwheel carried by the freely-movable shaft.

3. A plow attachment including a gagewheel, an approximately vertical supportingshaft for said wheel adjustable in the direction of its length, a clamping member adjustable about the axis of said shaft, an adjusting-lever, and a link connection between said lever and the clamping member.

4. A gage-wheel supported for rotation, a supporting-shaft for the bearing of said wheel, a clamping device including serrated halfboxes adjustably engaging the shaft and having upwardly-extending lugs, an adjustin lever, and a link connecting the latter wit 1 the lugs of the clamping device.

5, A box or bearing, a shaft slidable and rotatable in said bearing, a gage-wheel supported for rotation by said shaft, clampingboxes engaging the upper end of said shaft and having lugs engaging the upper extremity of the shaft, an adjusting-lever, and a link connecting the lever with the lugs of the clamping-boxes. I

In testimony that we claim the foregoing as our own we have hereto aflixed our signatures in the presence of two witnesses.
