WHEEL FledDec. 8; 1930 4 Sheets-Sheet 4- Inventor A liorney Patented Oct. 20, 1931 ANDREW R. TAYLOR, F PEPIN, WISCONSIN WHEEL Application filed December 8, 1930. Serial No. 500,883.

This present invention relates to a wheel for use on tractors and the like and has for its prime object to provide means whereby lugs may be retracted inwardly of the wheel when not desired or may be projected outwardly of the wheel when needed for traction purposes.

A further important object of the invention resides in the provision of a wheel of this nature which is simple in its construction, strong and durable, easy to manipulate` thoroughly efficient and reliable in use and operation, and otherwise well adapted to the purpose for which it is designed.

lVith the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is an elevation of a. wheel embodying the features of my invention, parts being broken away.

Figure 2 is a sectionalV view therethrough taken substantially on the line 2 2 of Figure 1.

Figure 3 is a sectional view taken substan tially on the line 3 3 of Figure 2.

Figure 4L is a fragmentary plan view of the inner periphery of the wheel rim.

Figure 5 is a perspective view of one of the lugs.

Figure 6 is a fragmentary perspective view showing a portion of one of the rings.

Figure 7 is a fragmentary section taken substantially on the line 7 7 of Figure 8.

Figure 8 is a similar view showing the lugs projected, and

Figure 9 is a sectional view taken substantially on the line 9 9 of Figure 3.

Referring to the drawings in detail it will be seen that the numeral 5 denotes a hub 7 formed at each end with an annular outwardly directed ange 6 to which are fixed series of outwardly extending spokes 7 on the outer ends of which is attached a rim 8. This rim 8 is formed with three annular ribs 9, one at each edge thereof and one at the center thereof. The rim 8 is formed with two annular series of openings 10 one series on each side of the center rib 9 and the openings of the series are in staggered relationship. f

The hub 5 is formed with an exterior annular groove in which is rockable a sectional sleeve 12, the sections of which have ears 13 bolted together as at 14. This sleeve 7 is formed with outwardly directed annular'A flanges 15 at the ends thereof to which are fixed two series of outwardly directed spokes 16 one series converging outwardly toward the other. On the ends of the spokes 16 there are fixed rings 17 with braces 18 therebetween. These rings 17 are formed in theirouter edges with spaced notches 19. These rings are disposed inwardly of the rim, are spaced from each other and are spaced in wardly from the spokes 7. A plurality of lugs 20 are formed at their outer ends with ground engaging edges 21 and at their inner ends with projections 22.

The projections 22 are adapted to rest on the outer edges of the ring 17 or in the notches thereof. Arms 23 extend rigidly from the l lugs 20 at their inner ends and are pivoted as at 24 to the inside of the rim 8. Springs 25 on the arms 23 impinge against the rim 8 to normally hold the lugs 2O inwardly.

A channeled brake rim 27 is carried to one side of the wheel by means of brackets 28 fixed to intermediate portions of one series of the spokes 16. A brake band 29 is operatively associated with the rim 27. Thus when the wheel is rotating in one direction, for example, in Figure 7 in a counter clockwise direction the rim 27 may be momentarily stopped thereby stopping the rings 17 and causing the lugs to ride out of the notches and to be projected from the position shown in Figure 7 to the position shown in Figure 8. Naturally by rotating the wheel in the opposite direction and braking as above mentioned jlthe springs 25 will be allowed to retractI the ugs.

It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent to those skilled in the art without a more detailed description thereof.

The present embodiment of the invention has been disclosed in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the detailsv of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or sco e of the invention as hereinafter claime or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

In a wheel of the class described, a rim havin a plurality of openings, lugs movable t rough the openings, a rotary element engageable with the inner ends of the lugs and having notches to receive said inne-r ends and allowing the lugs to be retracted so that the rotary member may be turned thereby projecting the lugs, arms extending from the lugs and pivotally connected to the interior of the rim, springs on the arms impinging against the interior of the rim to urge the lugs inwardly, a hub, spokes from the hub to the rim, a sleeve rockable on the hub, spokes connecting the sleeve with the rotary member, brackets projecting from the last mentioned spokes, a brake rim on the bracket, and a brake band associated therewith.

In testimony whereof I aiix my signature.

ANDREV R. TAYLOR.
