such as are used on tractors and the like for hauling farm implements, being more particularly a wheel which is equipped with devices to render the employment of such wheels eflicient in sandy soil.-
In common forms of traction wheels, when used in sandy soils, the tendency of the flights on the wheel is to dig out the soil and partially bury the wheel as the sand offers little resistance to the action of the flights.
It is the principal object of my invention to produce a Wheel provided with stationary flights and movable packers mounted on the wheel which coact with the flights to pack the soil or sand behind the flights, thereby olfering suflicient resistance to the flights to prevent the digging action of the flights which takes place with wheels constructed in the ordinary manner.
Another object of my invention is to produce a wheel ofthe class described of simple form .which may be quickly adjusted for road travel so that the wheel presents a flat face or tread for riding upon the surface of the road.
Other objects and advantages will appear hereinafter from the following description and drawings. I

of designates the hub of the wheel from which extends outwardly a series of flat spokes 12, such spokes being jointed at their outer ends by two circular ribs 13, there being one such rib on eachside of the spokes. The ribs 13 are connected intermediate of the spokes by means of flat webs 15, such webs 15 andthe spokes being used for the purpose ofmounting flights 16 thereon. Each flight 16 con sists of a flat plate secured to the spokes and webs respectively by means of bolts 17, such flights extending outwardly from the wheel beyond the periphery flight 16 is provided with arearwardly extending flange 18 inner end of such flange resting upon the outer edge of the ribs13 forming bracing means for the flight. Each flange 18 is perforated, as shown at 20, to receive a bolt 21 upon which ispivotally mounted a swinging presser foot 22. Each presser foot 22 consists of a curved tread plate 2 1 of greater width than the ribs 13 and is provided with inwardly extending flanges 25 which embrace the flanges 18 on the flights 16. The bolts 21, heretofore referred to, extend through the flanges on the presser foot and through the flanges 18 of the flights, such bolts being secured by means of suitable nuts 26 thereon. I
It is to be noted thatthe curved outer face or tread of the plates conforms to a cirin section, of
part
Referring more particularly to the form wheel shown in Figs. 1 to 6 inclusive, 11'
cle formed by such plates when the plates are in their extended position, as indicated at 28 1n Fig. 1, the outward swinging movement of such plates being limited by the 111- ner face of the plates coming into contact with the outer edge of the flights 16.
The'wheel is provided with a flat tread which'is placed on one side of the wheel,
Patented May 16, 1922.
at each side thereof, the
of the ribs 13. Each The wheel, when used, operates in the following manner:
Assuming the wheel to be revolving in the direction of the arrow shown in Fig. 1, the lowermost flights enter the ground, indicated at 35, as shown, the sand or dirt between the flights being pressed upon and held in compact condition behind the flights by the presser feet 22. This action of the presser feet between the flights tamps or packs the dirt, as indicated at 36, behind the flights thereby providing resistance to the action of the flights'resulting in suflicient traction to permit propulsion of the vehicle in such soil. As the flights leave the ground, the presser feet are permitted to swing freely and as same the positions indicated in Fig. 1 while the wheel is making its revolutions.
When it is desired to move the vehicle over a roadway, the wheel is adjusted so that the surface of the roadway is not injured. This is done by means of an adjusting device which consists of a circular plate 40 provided with a series of slots 41 through which extend bolts 42 secured in one of the ribs 13, the plate 40 being held in desired position on the rib by means of nuts 43 threaded on the bolts 42. The plate 40 is provided with radially disposed arms 41% which extend outwardly from the plate 4C0, the outer ends of the arms being rounded and engaging under the tread portion of the feet 22, as shown in Figs. 4 and 5.
hen the wheel is being used inv the orchard, the plate 40 is adjusted to the full line position shown in Fig. 4, in which position the arms la extend over the ends of the bolts 21 preventing dislodgment. of such bolt-s, in which position a free movement of the presser feet is allowed. By moving the plate 40 so that the arms assume the dotted line position shown in Fig. l, such arms engage under the tread of the presser feet, holding such feet in dotted line position, and form a substantially continuous tread, as shown in dotted lines in such figure.
Figs. 6 and 7 show the wheel with the presser feet removed, in which form the wheel is partly attached for use in heavy soil.
In the form shown in Figs. 8 and 9, the movable presser feet are eliminated in which casethe flat spokes, designated at 60, extend. beyond the ribs 61, the outer ends 62 of such spokes forming flights. The webs, indicated at 63, are also extended outwardly, as indi cated at 64:, forming flights. The presser feet in this form are stationary and consist of plates 65 which extend from the bottom of one flight angularly to the top of the next flight. The action of this form. of wheel is of the same nature as that disclosed in connection with Figs. 1 to 6 inclusive, that is, the plates 65 pack the soil behind the flights, the soil in such packed condition offering the I necessary resistance to the flights. While I formed on the flights extend both forwardly and rearwardly as indicated at 70 and 71, the inner ends of such flange engaging the outer edge of the ribs and bracing the flights onv such ribs at both sides instead of on one side as shown in the other figures.
lVhile I have shown the wheel constructed with eight spokes and webs connecting the ribs intermediate the spokes, it is to be understood that I may increase or decrease the number of spokes and that the webs may be eliminated without departing from the spirit of my invention.
