TRACTOR WHEEL.

Application filed January 17, 1919. Serial No. 371,725.

To aZZ whom e't may concern:

lie it known that I, LOUIS E. SLAUsoN, a citizen of the United States, residing at Moline, in the county of Rock island and State oi. Illinois, have invented certainnew and useful Improvements in Tractor \Vheels, of which the following is a specification.

My invention relates to tractor wheels, of that class which are provided with sectional shoes or tread members, to assist in the sup port of the wheel when traveling over sot't ground. In; practice, the soft ground. is usually also of a wet and stick 1 character, so that with many Wheels of this class the at tachments to the rim soon become filled with f the earth, and are rendered more or less inoperative. The principal purpose of the present device is to provide a wheel having a solid rim, and sectional attachments there- :lor, which rim and attachments will be mutually self-cleaning.

My device is also of a simple and durable construction, and possesses. a maximum amount of elliciency.

In the drawings:

Figure 1 is a side elevation of a wheel embodying my invention, with the sectional attachments removed. Fig. :2 is a side view of one of said attachments. Fig. is an end view thereof. Fig. l is a side elevation of a complete wheel. Fig. 5 is a longitudinal section on the broken line ar-zc oi Fig. 3.

1 represents the hub of a wheel of usual pattern, 2 the spokes, and 3 the rim thereof. At regular intervals the rim is provided on its outer face with rim elements, preferably in. the form ol. pairs of teeth 4;, and on the inner face with bearings 5, which may be cured in place by the same fastening means which hold the teeth 4, as a matter of convenience and economy. Each of the bearings 5 is provided With a pin 6, on the ends of which are supported plates 7, by means of openings 8 of substantially larger diameter than the pin. At their outer edges the plates 7 are formed into treads 9, having outwardly projected teeth 10. These teeth are united by bars 11, (F 5.) which conform outwardly to the shape of the teeth, and have fiat inner faces for engagement with the face of the rim 3. The edge of the tread 9 is recessed between the teeth 10. as at 19, and the bars 11 are spaced apart, as shown.

9 are permitted In the movement of the wheel the treads a limited amount oi move ment with relation to the rim, by reason oi? the loose connection between the plates 7 and pins 6. As a result, when the shoe is at the bottom oil. the wheel, and in engagement with the earth, the shoe will be forced upwardly to its farthest inward movement, with the teeth a projecting through the recesses 12, and alternating with the teeth 10 and bars 11, forming together one complete shoe or tread. In the continued movement of the wheel, as soon. as the shoes are free from the ground they drop awayv from the rim by force of gravity, and the teeth 4: are practically withdrawn between the treads 9.

Any earth which has collected upon the teeth 4 is thereby forced off, leaving these teeth clean. When the shoes reach the upper portion of their travel they drop back to the wheel rim and their movement relative to teeth at cleans the shoes. The teeth 4 not only assist the wheel in getting a footing in the soft ground, but they also act as'plungers, working outwardly through the spaces between the bars 11, and keeping such spaces free from dirt. When the tread members arrive at the lower part of the wheel they again drop outwardly, there being two complete .movements thereof inwardly and outwardly in each rotation of the wheel.

As the tread sections approach the ground they hang at such an angle with relation to the rim 3 that they are in a proper position to come in contact with the earth. This is true on either side of the wheel so that it is immaterial in which direction the wheel ll'lO V", ing.

It will be seen that the treads 9 add to the width of the rim to the extent of the thickness of such treads, which thickness may be increased in any reasonable degree. At the time that the greatest pressure is being exerted. when the treads are at the bottomot' the wheel, each pair of treads is practically in alignment with the rim.

What I claim and desire to secure, is:

1. The combination with the rim of a wheel, of a bearing on the inner face of said rim, a pin projecting at the sides of said bearing, and a shoe comprising a plurality of transverse ground engaging bars spaced apart, and sides connecting said bars and having enlarged openings therein to engage the ends of said pin.

2. The combination of the rim of a traction wheel of an outwardly extending proection on the rim thereof, a transversely disposed pin on-saidrim spaced inwardly from said projection, and a shoe comprising a plurality of ground engaging elements spaced apart, and sides connecting said elements and having enlarged openings therein engaged by said pin.

In testimony Wl1QI'QOf,I affix my signature.

LOUIS E. SLAUSON.
