POTATO-PLAOW.

. SII-lEClIFICA'IIIION forming part of ll'ietters Patent No. 567,475, dated September 8, 1896.

` 'Applicationnaretmay 20,1896. salaire. 580,104. momen-.1a

To all 1071/017@ it may concern.'

Beit known that I, Louis HINDERMEIER, a citizen of the United States, residing at Mecosta, in the county of Mecosta and State of Michigan, have invented certain new and useful Improvements in Potato-Flows and I do hereby declare the'following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relatesto improvements in potato-plows in lwhich a positively-driven clearer and separator is hung over the plowshare to rotate in a plane substantially at right angles to the line of draft of the implement, and which operates to break up the slice or furrow as itis raised by the share, so as to separate the potatoesfrom the soil and to deliver orthrow the potatoes to one side of the furrow onV top of the ground.

' The object of my invention is to provide a simple construction in which the rotary clearer and its driving devices may be readily adjusted to regulate the-depth of penetration of the plowshare without interfering with the operation of the clearer.

With these ends in view, my invention consists in the novel combination of devices and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to understand my invention, I have illustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in whichj Figure lis an elevation looking at one side of the implement. Fig. 2 is a top plan view thereof. Fig. 3 is a vertical cross-sectional view on the plane indicated by the dotted line @c a; of Fig. l. Fig. 4 is a detail sectional view of the ball-and-socket bearing for one end of the clearer-shaft. Fig. 5 is a detail view of the clearer.

Like letters of refe-rence denote corresponding parts in all the figures of the drawings.

A designates the plow-beam,which is integral with or rigidlyunited to the foot or stock B. On the foot B is secured the plowshare C, which, in the embodiment shown in the drawings,`consists of a double share set in an inclined position and substantially at .right angles to the line of draft of the implement.

and the rear end of the beam is forked te\ provide the armsa, which overlap the upper end of the stock B, the parts being united solidly by the through-bolts b. This foot or stock is provided at a suitable distance above the upper edge of the plowshare with a recess c, over one side of which is secured a capplate or boxing d, 1the whole'for'ming a spherical bearing E for the accommodation of the ball-shaped or spherical head'cl on the rear end of the clearer-shaft D. This construction forms a ball-and-sock'et joint or bearing between the plow-frame and the clearershaft, which permits the shaft to rotate freely in the bearing, and also enables the shaft to be inclined or raised and lowered at will without disturbing the connection between the rear end of the shaft D and the plow-l frame and without interfering with the free rotation ofthe. shaft. Over the front and rear edges of the stock B and the rear end of the beam A are applied the face-plates f f', which. overlap the joint between the stock and beam and which are 'fastened in place by suitable attaching means. I would have it understood, however, that the detailed construction of the beam and stock herein shown and described is not essential to my invention, and such construction may be modified and changed by a skilled mechanic Without departing from the spirit of my invention.

The clearer-shaft D. runs longitudinally of the implement below the beam A, and at a suitable distance above the right-angled set double share C; The rear end of 'this shaft D' is joined to the plow-frame by the ball-andsoekct bearing E, hereinbefore described, and the front part of this shaft is journaled in a bearing g at the lowerend of the'hanger G,

which is attached to the plow-beam near its ysembled and joined together.

.hangers J J.

front part in avmanner to adjust the hanger vertically on the plow-beam. Such construction of the vertically-adjustable hanger G (shown in Fig. 2) contemplates the provision of a longitudinal slot g in the hanger, through which slot passes a headed bolt g", that also passes through the beam and serves to clamp the hanger to the beam; but the detailed construction of the hanger may be modified .as desired.

The rotary clearer D is in the form of a spider, and preferably con-sists of a hub d, a series of radial arms d', and a series of toothed heads d at the outer extremitiesof the radial arms, all of which parts are preferably integral with each other, so that vthe clearer or spider constitutes a single casting, although the parts may be made separately to be as- The heads d are enlarged and formed with the plurality of teeth `or tines, and the head-s ,are arranged to be parallel to the axis of the hub d, so vas to ycause the toothed heads to sweep through thesoil or furrow raised by the share C. The spider-like clearer has Vits hub lfitted kon and clamped to the shaft Dso as to lie above the share and to sweep below .the arch a of the beam, and said clearer is .arranged to rotate in a plane at right angles to the line of draft of the implement.

As a means for rotating the shaft and the clearer thereon l have devised the groundwheel H, the .gearing l I, and hangers to support the shaft for the gearing and wheel in a manner to adjust the kground-wheel and the gearing correspondingly to the adjustment of the shaft D, whereby the ground-wheel may be adjusted to regulate the penetration of the share and the depth of the furrow.

The ground-wheel H is arranged at one side of the plow-beam, and it is of such diameter as to lie between the line of the beam and the share C. This wheel l-I is fixed to a transverse shaft h, which is .at right `angles to the beam A and is journaled in bearings jj on the lower lends of thc vertically-adjustable These hangers are slotted at their upperends, .as at lr., for the passage of the clamping-bolts 7c', and said hangers .are

lspaced apart a vsuitable distance .to accommodate a bevelsgear L between them, said bevel-.gearbeing fastenedto :the ground-wheel shaft 7L, so that Athe ground-wheel and the gear rotate together. One of the hangers is adjustably clamped by its bolt 7c to the beam A, but the other hanger is adj ustably clamped to a bracket M, which is bent at its middle so as to stand off to one side of the beam, and which is bolted at its `ends to the beam, as shown by Fig. 2.

.'llhe frontend of lthe shaft D is extended or carried through the front hanger-bearing, .and to said end is secured a bevel gear-wheel L, which meshes with the bevelgear L, whereby the vtwo shafts D h are geared -directly together and the .shaft D' is adapted to be driven by the ground-wheel I-I.

Although l have shown the device for sup porting Athe ground-wheel and its shaft as consisting of two independent hangers J J, which are attached, respectively, to the plowbeam and to an offstanding bracket thereon,

yet it is obvious that a single hanger may A be constructed to sust-ain the ground-wheel shaft. j

The operation may be described as follows: When the implement is drawn across a potato field, the ground-wheel H rides on the ground in advance of the share U so as to rotate and to drive the shaft D positively, and the share C penetrates the ground and raises the furrow or soil'into the path of the clearer D. This clearer D is positively rototed in a plane kat right vangles to .the line of draft ,of the implement, and as the toothed heads d are forced 'through the soil 'the Aclearer breaks up `the furrow and throws the potatoes to ione side of the line of movement of the implement. The potatoesare partially cleaned from the :soil and .are delivered to one side of the implement, so that they can be easily gathered. The ground-wheel H may be raised or lowered for the purpose of regulating the penetration of the share by the proper adjustment of the hangers J J, yand the hanger G for lthe front end of the shaft is adjusted corresponding 'to 'the adjustment of the ground-wheel, in order that the gears L L/ may properly mesh together. This adjustment for the front end of the clearer-shaftdoes not disturbthe bearing for the rear end of said shaft, because the balland-socket bearing permits theshaft D to be raised or lowered as desired.

Having thus fully described my invention, what I claim ,as new,.and desire to secure by Letters Patent, is-
