Abstract: An anti-skid device includes a first main body and a second main body disposed rearward of the first main body, both of which are made of elastic material. The first main body has: a first ground-contactable sheet-like part that elongates in a circumferential direction; an inside rear connecting part provided at rear side of the first ground-contactable sheet-like; and an outside front connecting part provided at front side of the first ground-contactable sheet-like part. The second main body has: a second ground-contactable sheet-like part that elongates in the circumferential direction; an inside front connecting part provided at front side of the second ground-contactable sheet-like part; and an outside rear connecting part provided at rear side of the second ground-contactable sheet-like part. The inside rear connecting part of the first main body and the inside front connecting part of the second main body are connectable with each other.

Abstract: A lightweight device for obtaining improved traction efficiency of rubber tired vehicles without adding ballast weight. The device has high-strength, thin-gauged traction intensifying means secured to a driving tire, providing higher drawbar pull at higher rate of travel speed by utilizing stronger sub-surface soil and extended tire life; and includes actuating means, for engaging and disengaging the traction enhancing means for convenient conversion to allow travel on pavement.

Abstract: An antiskid device and its fittings for a tire including a side chain, a cross chain, a connector, an end link, a hook and a stopper. The side chain includes a side link formed as a two-piece link having two links, one a long link and the other a short link, which are integral with each other. The stopper is angled in transverse cross section and formed with a transverse web of a width large enough to contact a lower portion of the end link and a groove of a width large enough to receive the hook. The cross chain is formed as a cross link of bar material, and the connector is in the form of a link on either end and in the form of a rod in its intermediate portion so that the connector is connected at one end to the cross link and at the other end to the side link.

Abstract: A vehicle tire with tractive elements for positive engagement with the ground surface is disclosed. The tire carcass has a tread including raised features. Means for positively linking tractive elements positioned radially outwardly of the tread to the raised features of the tread are provided in the form of a flexible but substantially inextensible belt positioned radially outwardly of the tread, and retainer elements positioned radially inwardly of the belt, the tractive elements being positioned radially outwardly of the belt and being releasably attached to the retainer elements for clamping the belt tightly therebetween. Inflation pressure within the carcass expands its crown region to maintain the belt in a taut condition. The retainer elements are sectionally constructed to facilitate assembly and disassembly of the tire.

Abstract: A vehicle tire with tractive elements for positive engagement with the ground surface is disclosed. The tire carcass has a tread including circumferentially spaced raised features. At least one flexible but substantially inextensible belt is positioned radially outwardly of the tread, and a respective plurality of retainer elements are positioned radially inwardly of the belt, the tractive elements being positioned radially outwardly of the belt and being releasably attached to the associated retainer elements for clamping the belt tightly therebetween. Inflation pressure within the carcass expands its crown region to maintain the belt in a taut condition, and at least one element of each set of associated tractive and retainer elements is positively mechanically linked to at least one of the raised features of the tread to limit circumferential displacement of the tractive elements relative to the tread.

Abstract: A skid protecting device for use in combination with vehicle tires, according to which in distribution over the tire circumference there are provided holders with a plurality of gripping profiles which are arranged transverse to and in covering engagement with gripping profiles which are adapted by way of tensioning members to be connected to the outsides of the holder. The arrangement comprises at least one chain net of interengaging chain links which is located on one lateral surface of the tire. This at least one chain net has one rim portion provided with serially arranged connecting links arranged in spaced relationship to each other for connection to the holders, whereas an oppositely located other rim portion is provided with a tensioning or tightening strand extending along the last mentioned other rim portion.

Abstract: Certain sulfonamidoquinolines and metal complexes thereof both of which are soluble in essentially water-immiscible organic solvents. The sulfonamidoquinolines have the structural formula ##STR1## where the R, R.sup.1 and R.sup.2 groups and m and n are as defined in the specification and claims hereof. Solutions of the sulfonamidoquinolines and the metal complexes thereof in essentially water-immiscible organic solvents.

Abstract: A seal between the surface of a traction shoe and the belt of a removable track for a tire in which the belt-engaging surface of the shoe has a groove extending axially of the track. An elongated sealing member is located in the groove and has a thickness greater than the depth of the groove for sealing engagement with the shoe-engaging surface of the belt. The groove may extend along the side and end edges of the shoe and the sealing member may be an endless strip of material providing a seal completely around the belt-engaging surface of the traction shoe.

Abstract: A pneumatic spacer and cushioning tire assembly is provided with a carcass component and a tread section component. A plurality of anchor plates are molded into the tire carcass in the crown section thereof. The anchor plates are further retained in position on the tire carcass by an elastomer insulated inextensible filament reinforced ply composed of a plurality of inextensible filaments which comprise a portion of the tread section component.The anchor plates are equipped with fastener receiving means which are provided to allow the fastening of traction plates to the anchor plates. Traction plates, once attached firmly to the anchor plates, protect the tire from damage as well as providing increased traction.The complete tire assembly provides an armored resilient ground engaging unit for use on construction equipment.
