LINK- FOR CROSS-CHAINS or A-N'rIsKIn Devices.

To all whom it may concern:

Be it known thatl, F ANKAVERILL Fox,

' a citizen of'the United States, residing at.

' referred to [as to enable the ends of Brooklyn, in the county of Kings, State of- Xew York, have invented certain new and useful Improvements in Links for Cross- Chains of Antiskid Devices, of which the following is a description, reference being had to theaccompanying drawings, forming a part hereof. I I I a My invention relates to cross chains for "antiskid devices for tires of automobiles and so firmly held that they cannot be pulled out in' use, and at the same time the links may be made and the cross chains assemblec at comparatively slight cost.

With these objects in view my invention consists in the construct-ion and combina tion of elements hereinafter described and claimed.

Referring to the drawings Fi ure 1 is a bottom view of a side link. embbdying my invention; Fig. 2 is a side view of the same; Figs. ,3 and 4: are cross sectional views on lines u-- a and Z) respectively of Fig. 1 Fig. i) is a plan view of a cross chain having side links of the construction shown in Figs. 1 to 4. inclusive; Fig. 6 is a bottom view of a center or master link having tongues; Fig. 7 is a side view of the same, and Fig. 8 is a bottom view ofa cross chains having the center or master link shown in Figs. 6 and 7.

In the drawings 1, in Figs. 1 to 5 inclusive, is the body portion of a side link of a cross chain. From ne end of the body portion extends atongue 2, which is of substantially uniform width throughout.

From the other end of the body portion 1 extends a tongue 3, which is narrower midway its ends than at its ends, its end portion 4 being of the same width as the tongue 2.

In the back or bottom face of the body ortion 1 is formed a recess 5 extending Specification of Letters Patent.

Application filed December 6, 1911. Serial No. 664,218.

from end to end of the body portion in line with the

tongues

2 and 3, and'o-f a fleptl'i corresponding to the thickness of the end portions of these tongues. ing of uniform depth, that is, having its bottom parallel with and at a uniform distance throughout its length from the front faceofthe link, and being of uniform width throughout, is readily machined to the pre cise "dimensions desired. Near their ends the tongues 2Land are providedwith oppositivelyformed recesses 6 near, butnot at the ends of, the tongues, the ends 7* beyond theserecesses being of the full width and thicknessof the end portions of the tongue. At the sides of the recess 5 in the body portion of the link are formed. lugs 8 airanged in pairs, and of such shape-and size that when bent over they will each fit and fill one of the recesses 6 in anend portion of one of the tongues. When the lugs flare bent down into the recesses 6 they notably hold the end portions of the tongues against the bottomofthe recess 5, but *alsoi by reason of the ends 7 being of full width and thickness; interlock with the recesses, effectively holding the tongues against'longi tudinal'strain. The tongue-Q' and 3 are preferably of such length that their ends will-abut-when bent. into the recess 5, and the lugs 8 when bent down into the recesses completely fill them, so that the inner surface of the body portion of the link presents a smooth practically unbroken surface.

In Fig. 5 is shown a chain comprising side links of the construction shown in Figs. 1 to at inclusive, with a center or master link 10 having loops 11 through which the tongues 2 are passed before their ends are bent over into the recesses 5, these loops This recess be- 11 being preferably formed integral with the body portion of the link.

In-Fig. 6 is shown a center or master link embodying my invention; having both of its tongues 2 of substantially uniform width throughout their length, the body portion of the link having the recess 5 of uniform width throughout and arranged the same as in the form shown in Figs. 1, 2 and 3.

The tongues have the recesses 6 and thesolid end 7, and the body portion is provided with the lugs 8, which are adapted to be turned down into the recesses 6, as in the form shown in Figs. 1, 2 and 3. With the form of center link the side'links are nec- 2. A vices comprising a body portion having 'a essarily provided at their ends contiguous to the center link with loops 1?. to receive the tongues 52, as shown in Fig. 8.

Having thus described my invention, What I claim is:

1. A link for cross chainsoi antiskid devicescomprising a body portion having a recess in its back or bottom face, a tongue extendlng from one, end of the} body portion having its end portion. adapted .to fit.

the recess in the body portion and having opposite recesses formed in its end portion near but not extending to its end, and oppositely arranged lugs on the body portion. adapted to be turned down into and to fit the recesses in the end portion of the tongue. I

link for cross chains of antiskid derecess of uniform .width throughout its length formed in its back or bottom face,' a tongue extending from each end ofthe body portion, the tongues having their end portions adapted to fit the recess in the body portion and each having oppositely arranged recesses in its end portion but not extending to its-end, and pa s of oppositely arranged lugs formed on the body portion adapted to be bent down into said recesses in the endportions of the tongues.

p A link for cross chains of antiskid devices comprising. a bodyfportion having a recess of uniform; width" throughout its length formed in itsbaek or, bottom face, a tongue extending. from eaohend of the body portion, the'tongues having their end Copies of this patent be obtained for portions adapted to fit the recess in the body portion, the tongues being of such length'that'their ends abut When bent into the recess in the body portion, the tongues having oppositely arranged recesses in their end portions not extending to their ends, and pairs of oppositely arranged lugs on the body portion adapted to be bent down into the recesses in the end portions of the tonguesto iock them against strain.

4. A link for cross chains for antiskid devices comprising a body portion having a recess of uniform Width throughout its length formed in its back or bottom face, a tongue extending from each end of the body portion, the tongues having their end portions adapted to fit and fill the recess in the body portion and each having pppositely arrangedrecesses in its end portion but not extending to its end, and pairs of oppositely arranged lugs on the body portion adapted to be bent down into and to -fi11 the; recesses in'the end portions of the tongues,-the parts being so proportioned that when the tongues are bent into the recess in 1 the body portion and the lugs are bent into the recesses in the end portions ofthe tongues, the back or bottom face of the link presents, a practically unbroken surface.
