CORN- PLANTER.

Ap,p1ication-fi1ed: June 15,1925. SerialNo. 37,248

To (.121 whom it mraytonccm:

lie it known that I, Grocer. M... Yecnrnr, a'citizen of the United Stat-es of Amer ca,

and resident; of irvocznin the county oflhirrray and. State of Minnesota, have invented certain new and useful TlHPIOVQlDGiltS in Corn Planters, of which the following is a specification.

D This invention relates to attachments for shoes or runners. of corn planters; and has for an object the provision of an attachment for. such shoes that will. be effective to prevent the accumulationof sod, grass,

stones or the like inthe pa th. of. travel of the sled shoe; It is well. knownthatwhen the sled shoe travels over stones, grass or sod, they often. interfere with proper. dropping of corn in hills and so deflect thecorn as to cause it to be carried, and distributed.

or scattered more widely.

It 135111 ob ect of this invention therefore to provide means for deflecting stones and those objects which might interfere with the proper deposit of corn While being planted and it is a further object to provide an attachment for the deflecting means whereby it may be secured to the sled runner for movement in the event of the deflector striking a stationary object or one that is comparatively unyielding as when a rock or stump is struck so that the deflector will be released to move without liability of injuring the deflector, the sled shoe, or parts by which the deflector is connected to the sled shoe.

"While this device has hen referred to as a deflector, it may also be termed a trip stub shoe or it may be otherwise designated as its oflice or function is to prevent the accumulation of the objects under the shoe by deflecting the said objects, therefore the term adopted will, it is thought, be sugges tive and proper.

It is a further object of this invention to provide means for pivotally connecting the deflector to the shoe at one end or at the front end of the shoe and to provide an adjustable connection for attaching the deflector to the shoe near the rear end of the deflector and at a suitable point between the ends of the shoe, said attaching means also including friction holding instrumentalities by which the deflector is held by friction against movement under normal conditions of use, it being understood that the friction will be overcome if the deflector strikes an unyielding objector one that will tend to fracture the parts ifno provision were made for releasing the deflecton.

It is a further object of this invention to produce a device of the character indicated which can be installed oncornplanter shoes now incommon use or which maybe associated with those newly constructed, 7 i

\Vith tlie foregoing and oth-er: objects in view, the invention consists inv the details of construction, and in the arrangement and combination of parts to be hereinafter. more fully set forth. and claimed.

In ,describing the. invention in. detail, reference willibe had. to the accon'ipanying drawings 7 forming partof. this application, whereii rlike characters denote. corresponding". parts in the several views, and; in whicli- Figure l illustrates a. view inperspective of a shoe embodying the inventioll applied;

Figure 2 illustrates a plan view of a part thereof partly in section;

Figure 3 illustrates a View in elevation of a fragment of a shoe with the deflector having a plurality of apertures for connecting it to the shoe at two locations; and

Figure 4c illustrates a View on the line %t of Figure 3.

In these drawings 5 denotes a corn planter shoe of conventional type, and 6 the deflector which comprises a plate-like element having a beveled front edge. 7 which tends to cut through sod or other soft material to produce a partial clearance for the reception of the shoe. The deflector has an aperture 8 to receive a fastening 9 m the nature of a bolt that extends through an aperture 10 of the shoe. The joint between the parts just described is such that the deflector will oscillate or pivot on the fastening 9.

Between the ends of the shoe, its upper edge is provided with a recess 11 forming a seat for a bolt 12 which bolt projects through one of the apertures 13 formed in the deflector and by reason of the plurality of apertures, the deflect-or will be held at different positions of adjustment.

A washer or relatively large disk 14 is applied to the bolt in position to bear against the surface of the shoe 5 and it is the purpose of the inventor that. under normal conditions of use, the deflector will be held by friction, due to the engagement of the disk 1a and the shoe, and that if the deflector encounters an obstruction, the force of the impact of the deflector and obstruction will overcome the friction which retains the deflector so that it will yield and oscillate on its pivot toclear the obstruction without doing injury to the deflector or parts with which it is associated. 7

As the deflector can be made from plate or sheet metal by the stamping process, it will be comparatively inexpensive to manufacture and its installation will not be costly.

In the form of invention shown in Figure 3, the deflector 15 has a plurality of apertures 16, either one of which may receive the fastenings 17 which correspond to the fastening 9 and the said deflector will be held at diflerent positions of adjustment between the ends of the shoe 18 by a bolt 19 and washer or friction disk 20, as heretofore described. 7

1. In a corn planter, a shoe having an aperture near its front end, a pivot therein, a deflector extending downwardly in the path of travel of the shoe and comprising a plate having apertures to receive the pivot, whereby the deflector is oscillatably connected to the shoe, the said deflector having a plurality of apertures near its rear end,

39 said shoe having an open slot in its upper edge forming a seat with relation to which the apertures of the deflector may be adjusted, a friction disk bearing against the side of the shoe at-the seat, and means carried by the deflector and lying in the seat of the shoe for engaging the disk and holding it in frictional engagement with the said shoe.

2. In a corn planter, a shoe having an aperture in its front edge, a deflector com prising a plate adapted to extend downw'ard ly at the front of the shoe in the line of travel of said shoe, the said plate having a plurality of apertures near its front edge, a pivot in the aperture of the shoe adapted to enter one of the apertures of the deflector whereby the deflector may be connected to the shoe at different positions of adjustment, the said deflector having a plurality of apertures near its rear edge, said shoe. having an open slot in its upper edge forming a seat with relation to which the apertures of the deflector may be adjusted, a member extending through one of the apertures of the deflector and lying in the seat of the shoe, a disk on said member, and means for moving the said member for forcing the disk into frictional engagement with the shoe.
