l sHoE EOE TRACTOR WHEELS.

Application led October 2, 1922. Serial No. 591,829.

To all whom t may concern.'

Be it known that I, ARTHUR G. HoovER, a citizen of the United States, residing vat Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Shoes for Tractor I/Vheels; and I do 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.

This invention relates to an improved shoe for use in connection with a tractor wheel and one object of the invention is to provide a shoe which can be readily connected with a tractor wheel having a smooth faced felly and to so mount the shoe that it may have tilting movement circumferentially of the wheel and further have movement radially of the wheel, so as to permit the shoes to be brought into lia-t engagement with the ground while the wheel is rotating. This permits the shoes to be brought directly into fiat engagement with the ground and further permits them to be lifted off of the ground as lthe wheel rotates.

Another object of the invention is to so construct the shoes that they may be formedV rom strips of angle iron firmly connected to provide a shoe which will extend transversely of the wheel felly and be provided with side wings extending inwardly of the wheel for engagement by a retainer which extends between cleats secured to the inner face of the wheel felly.

This invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a plan view of a portion of a tractor wheel with the improved shoes applied thereto.

Figure 2 is a longitudinal sectional view taken along the line 2 2 of Fig. l.

Figure 3 is a transverse sectional view taken along the line 3-3 of Fig. l.

Figure 4l is a perspective view of one of the s oes.

This improved shoe will be used in connection with a tractor wheel having the usual spokes S and rim or felly F. This rim or felly will be provided with a smooth outer face and of course may be of any desired width and thickness according to the size of wheel. The improved shoes will be put in place about the circumference of the wheel and will be spaced a suitable distance apartas shown in Figs. l and 2 so as the wheel rotates, the shoesmay be placed in engagement with the ground and lifted olf of the ground.r In the present illustration, one shoe has been shown between each pair of spokes, but it will of course be Linderstood that the number of shoes and the relative position of the shoes with respect to the spokes will change according to the size of wheel and number of spokes provided. One of the shoes is illustrated in detail in Fig. 4 and since lthe shoes are of a duplicate construction, the following detail description of the shoe shown in Fig. l will suffice for all of the shoes.

This shoe is provided with sideY bars l which extend transversely of the wheel felly when the shoe is in place. Each of the side bars has been provided with an outwardly extending flange 2 for engaging the ground and causing the wheel to have a good engagement to prevent slipping when the ground is soft. Adjacent the ends, the side bars l have been connected by cross bars 3 which are firmly secured by rivets, bolts or other suitable fasteners I so that the bars will be firmly held in engagement and prevented from moving out of the proper relative relation to each other. These end bars 3 are provided with wings 5 which extend inwardly and radially of the wheel. Openings 6 are provided in these wings 5 so the shoe is put in place a pivot rod 7 which. is in the form of an elongated bolt may be pass-ed through these openings and a securing nut 8 put in place to securely hold the rod in the position shown in Fig. 3. Cleats 9 are secured against the inner face of the rim or felly F and extend from the rim as shown in Figs. 2 and 3 with the rod 7 extending between the cleats. The rods 7 are positioned a sufficient distance from the cross bars 3 to permit the shoes to have movement radially of the wheels. By having the rods extending in spaced relation to the rim as shown'in Figs. 2 and 3, the shoes may have the necessary movement towards and away from the rim to permit the shoes to move into fiat engagement with the ground and then after the wheel has turned over them, be lifted directly from the ground. In order to permit the wheel to be prevented from skidding transversely, there has been provided a center cross bar 10 which extends midway between the end bars and will have its end portions secured to the side bars l by bolts or other removable that when Mns-'warme 1. my im. xi im i m i Meeres fasteners ll. rlhis center cross har l0 is provided with a. side flange l. which extends outwardly and will engage the ground and sink into soft ground to prevent side skidding. These Center' bars' are removably secured so that when desired they can he removed and the shoes used without them.

I claim:

l. tractor shoe comprising a' frame having side bars having outwardly extending ground engaging flanges, end bars connectingsaid side bars and having iiange extensions pertorarted to receive a pivot rod., and a cross bar removably connected to said side hars, intermediate the end bars.

2. A tractor shoe Comprising a frame having side bars having outwardly extending ground engaging flanges, end hars connecting said side bars and having flange eXtensions perforated t0 receive a pivot rod, and

a cross 1oar removah y Connected to said side bars intermediate the end hars and having a ground engaging Vlianye extending at right angles to the iges or' said side hars.

3, A; trae-'tor shoe comprising a frame for extending across a wheel rim and having` its sides provided with ground gripping means, and its ends with extensions 'forming bearings', a cross 1oar removably mounted intermediate the width of said iframe and having ground gripping means extending at right angles tothe iirst mentioned ground engaging means for preventing side skidding of a. wheel, and a pivotrod carried by said bearings for engagement by ahntments carried by a wheel rim and extending upon opposite sides of the rod.

ln testimony whereof` I have hereunto affixed my signature.

ARTHUR G. HOOVER.
