LINK.

Application filed July 19, 1923. Serial No. 652,612.

To all who-m it may concern:

Be it known that I, HORACE O. CLARK, a citizen of the United States, residing at VVaukegan, in the county of Lake and State of Illinois, have invented a new and useful Link, of which the following is a specification.

This invention aims to provide a link, which, being used in duplicate, may be employed for uniting the ends of a broken cross chain on an anti-skidding device for vehicle tires, it being possible to use the link in single form on the side chain of an anti-skidding device, and the link being reinforced at one point, and weakened at other points, so that the link may be closed partially, without difficulty, when the link is used in single form.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that sort to which the invention appertains.

With the above and other objects in view, the invention consists in the novel construction and arrangement of parts hereinafter described, and depicted in the drawings, it being understood that, within the scope of what is claimed, a mechanic may make changes in the structure described and delineated, without departing from the spirit of the invention.

In the drawings :Figure 1 shows in side elevation, a link constructed in accordance with the invention; Figure 2 is a section on the line 22 of Figure 1; Figure 3 is an elevation showing two links used as a connector; Figure 4 is a view similar to Figure 3 but showing the links as they will appear when they are pressed against the ground, in use; Figure 5 is a section on the line 55 of Figure 4.

The link forming the subject matter of this application is made of plate metal and comprises a body 1 having rounded end edges 2 and parallel longitudinal edges 3 and 4, the body having overhanging arms 5, the ends 6 of which'are spaced apart to define an entering throat '7, there being openings 8 located partly in the body 1 and partly in the arms 5 and forming inwardly projecting lugs 9 at the ends 6 of the arms 5,

the openings 8 forming notches 10 in the inner edges of the arms 5. There is an inwardly projecting rib 11 along the inner edge of the body 1, the inner edge 12 of the rib 11 being parallel to the edge 3. When a pair of pliers or a like tool is applied to the arms 5 and to the body 1, as shown in dotted line in Figure 1, the arms 5 may be bent at the notches 10, because they are weakened there, to decrease the space between the lug 9 and the rib 11, thereby closing the link partially on the chain wherewith the link is assembled. The rib 11 is of such length and shape as to reinforce the body 1 when the arms 5 are bent at the notches 10 as aforesaid.

Two links, constructed as above described, may be placed side by side,'as in Figure 3, the entering throats 7 facing in opposite directions, one link closing the throat of the other link, and the members 14 of a cross chain in, an anti-skidding device, or the like being received in the openings of the links, the members 14 being insertable by way of the throats 7. When the article comes into contact with the ground, the links of Figure 3 are moved transversely into alinement, as shown in Figure 4, and the space between the ribs 11 of the links is decreased to such an extent as to preventthe chain members 14 from shifting from one end of the device to the other.

I claim:

A link of the class described comprising a body having overhanging arms of like out line, there being an inwardly projecting rib along the inner edge of the body, the rib having a straight and continuous longitudinal edge, the ends of the arms overhanging said longitudinal edge of the rib and being spaced apart to define an entering throat extended unbrokenly between the arms, there being openings located partly in the body and partly in the arms, the openings forming lugs at the ends of the arms, the lugs projecting inwardly toward said longitudinal edge of the rib, the openings forming notches in the inner edges of the arms, the arms being wider at the lugs than at the notches, the link being widest across the rib, and the arms tapering to the lugs, thereby to render the arms bendable at the my own, I have hereunto aflixed my signanotches to decrease the space between the hire in the presence of two Witnesses. lugs and said loiwitudinal ed e of the rib, and the rib being of such length and shape HORACE CLARK 5 as to reinforce the body against bending Vitnesses:

when the arms are bent as aforesaid. DORA M. H0011, In testimony that I claim the foregoing as RALPH L. K NG.
