Abstract: A tire chain comprising tread links formed with a perforation and connectors that are loops threaded through the perforations in three or more tread links interconnecting the tread links to form a network of closed figures. The connectors are loops of a carbon steel rod with the ends of the loops lapping each other and being welded together along the length of their adjacent surfaces. The tread links and connectors are of different carbon steels whereby after heat treating each is hardened throughout its thickness with the tread links having a surface hardness in the range 46 to 54 Rockwell C and the connectors having a core hardness in the range 15 to 35 Rockwell C.

Abstract: A tire chain having annular links and C-shaped links which are hooked into said annular links wherein one of the ends of the C-shaped link has a cross section which is decreased at the expense of its width thereby defining an introduction slot. The annular link has at least one narrowing whose shape corresponds to the shape of the end of the C-shaped link with the reduced cross section and retaining elements for the C-shaped link are provided in the narrowing. The retention elements are provided in the narrowings to prevent disconnection of the joined links.

Abstract: A tire chain with separable chain strands the end links of which are connectable at each separation point by use of two connecting elements which can be hooked into each other and which are each safely connected with an end link, wherein each connecting element has a body comprising at least one portion bounding an insertion slot which portion has a cross-section decreased at its free end at the expense of its width and wherein the width of the insertion slot is smaller than the height of each of those portions of the body which bound the insertion slot.

Abstract: A tire or similar chain shackle connector having an inlet for receiving links to be connected, the end of the chain at one side of the inlet being solid and at the other side having holes for receiving a connector, and a closure member having a recess for receiving the solid end of the shackle and apertures or holes at the other end of the closure member through which the connector can be inserted.

Abstract: A wear-resistant link for tire chains, including a link body having at least one link opening between a running surface and a tire engaging surface for engagement with at least one connecting link. The surfaces defining the link opening merge with an outside area of the link body for forming an insert opening on this outside area. The wear resistant link is furthermore provided with at least one lock for the insert opening which lock includes at least one bolt or the like in engagement with the link body. The insert opening is located between the running surface and the tire engaging surface of the link body, and the lock is provided with at least one engaging surface. The arrangement is such that the respective link opening or openings in closed condition is or are defined by at least one engaging surface for engagement with the pertaining connecting link when the respective tire chain equipped with the wear resistant link is in operation.

Abstract: A tire chain for tractors and the like includes a plurality of relatively large longitudinally aligned annular elements which are retained in the chain by means of laterally extending chain parts, and onto which are welded a number of plate members protruding in radial planes normal to the general plane of the annular element. The plate members serve both as claw means for the chain and as means for connecting the lateral chain parts of the annular elements.

Abstract: A tire chain for the protection and slip prevention of vehicle tires comprising a number of main metal nets and a number of supplemental metal nets, whereby the necessary number of main and supplemental metal nets respectively are disposed side by side in accordance with the peripheral length of the tire on which the chain is to be mounted and adjoining metal nets are connected together by suitable connectors.

Abstract: A chain link, a series of which can form a chain, the links having hook means at one end and a transverse bight at the other end whereby the hook means of one link can be detachably connected to the bight of an adjacent link. The hook means are formed by the ends of the legs of the link being turned back upon themselves so as to define a relatively narrow opening between the ends of the hooks and their respective legs. A transverse slot-like recess is formed in the legs adjacent the bight and at the end of the link opposite that on which the hook means are formed. The slot-like recess defines a narrower leg portion which is of a thickness less than the opening between the ends of the hooks in the legs so that in order to detach the chain links from one another, it is necessary to fold the links together so that the narrower leg portion can be slipped transversely through the relatively narrow opening of the hook means. This interlocking construction prevents inadvertent disengagement of the chain links.

Abstract: An anti-skid chain having horizontal links and at least one vertical shackle having arms surrounding the horizontal link and firmly connected thereto.

Abstract: A linkage arrangement for antiskid vehicle tire chains in which a web link in a plane perpendicular to the tire surface is pivotally linked to a substantially circular link which is parallel to the tire surface. The interengaging regions of said links are convex toward each other and vary not more than a small amount in curvature. The links are so configured within the region of pivotal interengagement thereof as to present cooperating elements of abutment means to one another which limits the relative pivotal movement thereof to about 90.degree. in the direction toward and away from the surface.

Abstract: A tire chain having horizontal links of high breaking strength and vertical links having high resistance to wear and tear.

Abstract: This product is a traction assembly designed primarily for heavy-duty vehicles, and comprises a chain assembly of unidirectionally distorted links in combination with rings connecting the same, and side chains holding the assembly securely upon the vehicle tire; the links of the traction portion having projecting lugs upon the outward face thereof, wherein the interaction of the rings and chains maintains the assembly in position for maximum contact of the lugs with the surface of the terrain.
