Patented July 1, 1947 UNITED STATES PATENT OFFICE WINDROWER ATTACHMENT Harry J. Fienhold, Pontiac, Ill. Application July 5, 1944, Serial No. 543,529

This invention relates to windrower attach ments and more particularly to means to prevent grain from the windrower from getting caught in the chains or sprockets of the machine or between the conveyor and roller at the end thereof, or between the platform and conveyor, or in a corner of the machine, etc. A further object is to provide an improved attachment for windrowers, which when in use in a field which had previously had corn therein prevents the corn stalks from getting caught ybetween the slats of the canvas conveyor thus stopping or impeding the machine.

A further object is to provide means for keeping the moving parts of the machine clear of all material that would clog, impede or stop same in operation and that may be provided as an attachment for the windrower or built into the Same at the factory.

A still further object is to provide a windrower attachment that is very simple in construction consisting ordinarily of a single piece of material, that is positive and efficient in use, inexpensive to manufacture, and durable.

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the claim and illustrated in the accompanying drawings forming part of this patent, and in which- Fig. 1 is a view in perspective of a windrower illustrating the application of the instant attachment.

Fig. 2 is a View in perspective of the attachment per se.

Fig. 3 is a fragmentary plan view of the con* veyor, pitch roller and certain closely associated d.parts of a Windrower showing the invention, an

Fig. 4 is an enlarged longitudinal vertical cross sectional view through Fig. 3 showing the invention and one method for securing same to the conveyor platform.

Like reference characters denote corresponding parts throughout the several views.

The reference numeral I` denotes the windrower having the usual reel 2, canvas conveyor 3, usually an end or pitch roller 4, and platform 5. Extending transversely of said platform and of a length equal to the width thereof and secured thereto by suitable fastening means is the built'with or attached device including the flat strip 6 of metal or other material formed with perforations 'I in its ends to permit the use og bolts or the like for securing it in place,

1 Claim. (Cl. 56--192) `platform with the Secured to or integral with said strip is the cone-shaped body 8 which extends laterally from one longitudinal edge thereof, said body portion while substantially cone-shaped preferably having one rather flat face 9 disposed the plane of said strip, the smaller end of said lbody portion being spaced inwardly from o-ne end of said strip to allow a free strip-edge portion Il), said body extendingapproximately a like distance beyond the opposite end of said strip. I

The attachment is secured to the windrower end Il of the strip substantially flush with the forward edge of they platform so that the narrow end of said body portion-8 isdisposed rearwardly of said edge a distance equal to the extentof the free portion I0, with the large end of said body portion extending rearwardly of said platform and of the machine itself, said strip being secured to the platform contiguous t0 the grain opening I2 in the windrower through which it projects rearwardly, said strip 6 being disposed immediately beyond the pitch roller 4, or beyond the conveyor and platform in the event said roller 4 is omitted, with the body 8 spaced therefrom.

Ordinarily grain travelling over the conveyor 3 is pitched by roller 4, or by the conveyor, upon the windrow. The heads of most grains are fluffy and not compact as are the stubble ends, more so when ripe.

I have illustrated a right hand type of windrower. The conventional type of windrower is driven either by the bull wheel I5 as in the instant case or by power take-off. The windrower is provided with the said usual grain opening, with theguide plate I'I preferably of heavy sheet metal that projects forwardly beyond the cutting bar I8 to encounter the standing or partly fallen grain and dispose same to the best advantage in the path of said bar; with the draw bar I9, with lever 20 for adjusting the height of the cutting bar above the ground, and with the reel adjusting lever 2l for adjustment of the reel 2.

The bull wheel is provided with a large sprocket that is chain-connected about but slightly from the grain opening I2 to the gearing for driving the canvas conveyer 3 and pitch roller 4 but this mechanism has not been illustrated as deemed conventional. Patent No. 2,071,844, February 23, 1937, shows an equivalent structure. The grain that is cut or on windrow does not cause any trouble by clogging or otherwise at the bull wheel end of the machine. As the grain is cutA it falls upon the conveyer, the butt ends fall nearest cutter bar I8 and the head ends remote therefrom as shown at 22, Fig. 3, the conveyer moving therewith in the direction of the arrow.

As the grain passes from the conveyer the cone 8 guides it away from the roller 4 and from the chains and sprockets of the machine and from lodgement at the corner formed by the left wall of the grain opening and the machine frame and falls upon the stubble in windrow. The head ends of the grain are nearest the large portion of the cone 8 and some of the grain will lie on the windrow as the machine moves forwardly. The grain will lie on a slight slant or angle to the path of the machine and this angle will vary somewhat, depending upon thev lengthv and ripeness of the grain. Grain lying on a slant to the windrow will pick up better with the combine. When the windrow becomes built up with loose and uffy grain some of the grain will ordinarily get caught at this corner or angular point of the machine and a bunch o1' bunches of grain may drag in the windrow until freed from the machine. This corner entanglement is positively prevented bythe instant attachment whichl serves as a guard against obstruction to the moving parts of the machine insuring its clean operation at all times.

Therefore the head ends will not pitch so far or so readily and sometimes getcaught in the chains or sprocketsof' the machine, or between the conveyor and roller, or between the platform and. conveyor. At such times the operator must get down and remove the impacted; grain which otherwise would halt the operation of the machine. The grain heads may contact the free edge I0 of the strip as the machine is in operation and ride along same and be lifted by the cone-shaped body 8, by the outer portion I 3 thereof and nally be deposited from the larger end of the cone upon the windrow clear of all parts of the machine, or the grain will be pitched clear from the cone.

The movement of the machine bringing the grain in contact with the attachment rolls and pushes the heads of the grain over upon the windrow. The lower end of the cone and the adjacent end of the strip meet the head ends of the grain first at an angle of approximately ten degrees or the like.

What is claimed is:

In combination with a windrower having a conveyer, a platform and a grain opening; a strip secured to saidv platform and extending beyond the same and said conveyer, and a tapered body secured to said strip along its remote lateral edge with its smaller end disposed forwardly and its larger end rearwardly beyond said strip and the rear end of the windrower, said body disposed transversely of the width of the windrower and contiguous toone wall of said grain opening.
