sPEOI'FIcA'rIoN forming part of tters PatentNO. 712,509, dated November 4,19o2. Amman fi1ed April27,1901; $erialNo. 57,669. (Noniod el J Be it known that I, SAMUEL K, DENNIS, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Harvesters, of

whichthe following is a specification. My invention relates to improvements in harvesters and especially to ground or master wheels for rice-harvesters, which are generally employed where the wheel travels over soft wet earth that readily adheresthereto andcoats the same. I

The objects of my improvements are, first,

to provide a masteror ground wheel of such construction and organization as will not take up any 8011 upon its tread portion, and,

second, to provide a simple and efficient arrangement of scrapers whereby such earth and refuse straw as adhere to the wheel will be shedded therefrom. p

The invention consists in the construction and organization of parts hereinafter fully ground-wheel embodying my invention;

Figs. 4; and'5 are detailed views of a form of ground -wheel exemplifying the preferred form of my invention in this respect.

Similar letters of reference indicate like parts throughout the various views.

The machine is supported upon a suitable frame (designated in general by the referenceletter A) carried by the ground or traction wheel 13, which is suitably mounted upon a main axle in any desired manner, with capacity for adjustment in guideways, formed by the sector-arms a, affixed to the inner faces 1" of the frame. This adjustment may beootained by any suitable n1eans-such as the pinion or, adapted to engage the teeth or pins a? of the sector-arms intheusual manner and operated by any suitable mechanism; I The wheel Btravels upon the surface of the field and serves to carry and transport the machine and to transmit power to drive the mechanism of which the machine is comcast shells b and b, respectively,each consisting of an approximately dish-shaped structure having a plane-surfaced body terminating in an angular peripheral portion b whereby the rim or. tread portion of the tiveposition,issubstantiallyV-shaped. The peripheral portions of the disks are preferably constituted of a series of inwardly-proj ectin g beveled faces I)? and have suitable bolt holes 19 at intervals adapted to receive bolts to securely fasten the shells or disks together.

For convenience in making a tight joint between the two shells comprising the wheel it is preferred to provide the edge of each shell with a narrow horizontal web Z1 these webs corresponding in outline and presenting flush faces to be held in close contact by the securing-bolts. The bolt-holes are preferably provided with housings b for the purpose of adding strength and bearing-surfaces at the points where the bolts are employed. The shells are preferably provided with interlocking means, which may be of any suitable description, such as lugs on one of the shells taking into recesses in the other, as indicated at b in the drawings. The inner faces of the disks may be provided with strengtheningwebs 11 if desired. The'wheel may be pro- .vided with a bearing in any suitable manner,

and I have shown a convenient arrangement wherein a hub b is cast integral with one of the around their peripheries with suitable ribs 17 which extend parallel with the axial line of the wheel and with their outer. edges in the same plane as or in extension of the outer face of their respective disks. These ribs are preferably disposed alternately with or intermediate with the beveled faces 11 0f the disks, and therefore are arranged at theangles formed by the meeting of adjacent inclined faces, which are angularly disposed with reference to each other. The beveled faces may be plane surfaces, but preferably they are'curved or concaved in cross-section on the peripheral line of thewheel, where theirends curve up to or merge with the ribs b the curvature toward each rib beginning at any suitable point. Each inclined face has therefore preferably rounded margins, which present no angles or corners to the soil, and as the inner edges of the beveled faces are preferably scalloped, as shown in Fig. 1, the ribs and faces merge into each other throughout the length of the former without forming angles or pockets in whichv the wet soil may pack. The ribs 19 of the disks may be disposed to come opposite each other or be arranged so that each pair, in effect, constitutes a single rib of approxi mately the width of the wheel, as shown in Figs. 2 and 3, or they may be arranged in alternate or staggered relation, as shown in Figs. 4 and 5. The latter arrangement is preferred, in which case each rib on one disk comes approximately opposite the median line of the opposite beveled face on the other disk.

In either arrangement it is preferred to terminate the inner ends of the ribs short of the apex of the rim of the wheel, whereby a central or peripheral channel 19 is formed between the inner lines of the ribs to receive a suitable scraping or doctoring edge to remove the accumulated straw and refuse matter taken up by the rim of the wheel as it travels over the soil.

Under certain conditions of use, as where the soil is unusually soft, the wheel will accumulate more or less mud upon its faces or sides, and in such cases it is desirable to provide means to remove it. An efficient and simple arrangement of parts for supporting scrapers, which it is desirable in such instances to employ for the faces of the wheel as well as the straw-scraper for the rim, is shown in Figs. 1 and 2. A suitable frame 0 is attached to the main frame of the machine and carries an adjustable rod 0, which projects to a point preferably below the central line of-the wheel, where it is-provided with a downwardly-inclined body-scraper c and a channel-scraper 0 The scraper c for the body of the wheel. is preferably in the form of a yoke bolted to the lower end of the rod and embracing the wheel, as shown in Fig. 2, so as to contact with both of its faces. -The scraper for the channel of the wheel is preferably in the form of a pointed or tapered plate and operates within the groove 17 of the wheel, being adjustable andheld in the box a at the lower end of the rod by a setscrew Power is transmitted to the mechanism of the machine from the master-wheel by any suitable arrangement and construction of parts. I I p In employing harvesters in rice-fields,which have a wet and sticky soil, the operation of the machineshas been seriously impeded by the accumulation of mud and refuse straw on'the traction or transporting wheel as it travels over the surface of the field. From a consideration of the foregoing disclosure it'is apparent that my improved wheel will not take up mud or moist soil, owing to the sloping or angular contour or outline of its tread portion. The curved shape ofthe beveled faces is especially adapted to prevent the earth from packing against the ribs, and the bevel or V shape of its parts are so shaped in angular disposition as to cause mud to easily drop off. The solid form of the wheel also prevents the mud from filling in about its claim as new, and desire to secure by Letters Patent, is

1. A closed master-wheel for harvesters constructed without spokes and composed of disks each provided with an inwardly-beveled periphery constituted of a series of angularly-disposed faces comprising the tread portion of the wheel.

2. Aclosed master-wheel for harvesters constructed without spokes and composed of a pair of disks each provided with a series of axial ribs and intermediate inclined faces.

3. A master-wheel for harvesters composed of a pair of disks having angularly-disposed peripheral portions, a hub integral with one of the disks and fitting a perforation in the other, and a series of axial ribs on each disk.

4. A closed master-wheel for harvesters constructed without spokes and composed of a pair of disks, each disk having a series of axial ribs extending beyond its peripheral line and intermediate inclined faces of rounded margins merging with the ribs.

5. Aclosed master-wheelfor harvesters constructed without spokes and composed of a pair of disks provided with axial ribs whose outer edges extend in the plane of the faces of the disks, and intermediate faces angular to the plane of the body of the disk.
