FELLY-ENGAGING ANTISKID-CHAIN-ANCHCRING lvIEANS.

Application led October 10, 1921.

T 0 all whom it may concern Be it known that I, GEORGE l). lliiclN'rosI-r, citizen of the United States, residing at 1V aketield, in the county of Middlesex and State of Massachusetts, have invented new and useiul improvements in Felly-Engaging Antiskid-Chain-Anchoring Means, of which the following is a speciiication.

This invention relates to an anti-skid device which includes a chain adapted to extend across the tire ot a vehicle wheel and anchoring means attached to the wheel telly and adapted to engage the terminal. links of the chain in such manner as to confine the r latter in its operative position.

The invention is embodied in certain improvements in the anchoring means, having tor their object the prevention of an automatic separation of the chain .from the :telly and the loss of the chain.

Of the accompanying drawings forming a part ot this speciication,

Figure 1 is an edge view of one form of anchoring means embodying the invention.

Figure 2 is a plan view of the same.

Figure 3 is a view similar to Figure 2, showing a different arrangement of the hooks hereinafter described.

Figure 4 is an edge view of the anchoring means shown by Figure 3, and of a chain engaged therewith and a sectional View of a telly and its tire.

Figure 5 is a section on line 5-5 of Figure 8.

Figure 5a is a view similar to Figure 5.

Figure 6 is a plan view of an anchoring means including two guarded hooks.

Figure 7 is an edge vieW of the anchoring means as shown by Figure 6.

Figure 8 shows an anchoring means made in two parts, tor use with fellies of maximum width.

Figures 9 and 10 show another form of anchoring means embodying the invention.

The same reference characters indicate the same parts in all of the figures.

ln the drawings. 12 represents a wheel felly and 13 an elastic tire thereon. The terminal links of an anti-skid chain 14 are engaged withA an anchoring means embodying the invention7 attached to the telly, said means being adapted to hold the chain in the form of a loop extending from side to side of the telly, and across the tread face of the Serial No. 506,535.

tire, this being the operative position of the chain. Said anchoring means in the embodiment or" the invention shown by Figures 1 to 7, inclusive, includes an attaching base 15, bearing on and extending across the rinner' surface ot the telly, and bolted to the latter, and a pair of hooks formed on said base.

' ln the embodiment of the invention as shown by Figures 1, 2, 3 and 4, the base is provided at one end with a` guarded hook adapted to be engaged with a terminal link by a suitable manipulation of the latter, and to prevent automatic or accidental separation of the link from the hook andthe loss of the chain, and at its opposite end with an unguarded hook adapted to cooperate with the guarded hook in securing they chain in its operative position. The guarded hook includes a curved neck portion 17 projecting outwardly from the outer side ot the i base 15, in the plane of the chain when the latter is in its looped operative position, and a terminal portion 18 overhanging the outer side ci the base, and provided with linkes 19, projecting in opposite directions Jfrom the plane of the neck portion, and formed to be engaged with a terminal link of the chain 14 by the manipulation illustrated by Figures 5 and 5a. The link is first held, as shown by Figure 5, at right anglesto the plane of the loop formed by the chain when the latter is in its operative position, the link being then slipped over the iiukes. The link is then swung to the dotted line position shown by Figure 51I and shifted on to the neck portion 17 and allowed to depend therefrom. The chain is linally adjusted in the form of a loop, as shown by Figure 4. The above-mentioned terminal link is now so engaged with'the guarded hook that it can be separated therefrom, only by a reversal of the described movements. and cannot be automatically separated or cast oil from the hook.

The unguarded hook includes a curved neck portion 21 projecting outwardly from the base 15 in the plane of the loop formed by the chain and an elongated finger-shaped terminal portion 22 overhanging the base. The form of the unguarded hook is such that, so long as the chain is intact, it is'retained in its operative position by the eooperation of the two hooks. I do not limit myself to the conjoint employment of a Q lasassf guarded and an unguarded hook, and may employ tivo `guarded hooks, as shown by Figures 6 and 7.

The base l5 may be secured by bolts passing through holes 24 formed in it, or by bolts passing through holes in ears l5 'rormed on the ends of the base and bearing on the sides of the telly as shown by Figure il. The hooks may be diagonally arranged. as shown by Figure 2, or in alinement with each other as shown by Figures 3 and 5.

As shown by Figure S, cach hook may have an independent base 15b, each adapted to be bolted to a felly. rlhe hooks and bases shown by Figure 8, are adapted 'for use with very Wide fellies.

As shown by Figures 9 and l0, the invention may be embodied in an anchoring;` means composed of a base 15C. adapted to bear on the inner side of the telly, ears 15d at opposite ends of the base. formed to bear on opposite sides of the telly, and to receive attaching bolts` and hooks projecting` Jfrom said ears, the form of the hooks and their arrangement relatively to each other and to i the loop formed by the chain beingas in the previously described embodiments of the invention.

It will be seen that in each embodiment of the invention the hooks are coextensive With Y the plate or base whereby they are supported and project therefrom so that when the base is attached to the telly the hooks project outward from the opposite sides of the telly. By virtue of this arrangement the end portions of chains Whose terminal links are engaged with said hooks extend substantially straight across the sides of the telly as shown by Fig. 4.

l claim:

An anti-skid-chain anchoring means, adapted to hold chain in the form of a loop eXtendinp across the tread of a Wheel tire and across the opposite sides or the telly, comprising` a base adapted to be secured to the inner tace of the telly7 said base being provided with hooks coextensive therewith and projecting;` therefrom to project out- Ward from the opposite sides ot the telly, so that the end portions of chains Whose terminal links are engaged With said hooks eX- tend substantially straight from the hooks across the sides of the telly, each hook being connected With the body or' the base by a ciu-ved neck whereby the hook is directed backward and overhangs the base. said means including; oppositely directed laterally extending; linkes so arranged that a terminal link ot the chain can only be engaged with the linkes by being); arranged in a position substantially at right angles to that occupied by it alter being' passed onto said curved neck.

ln testimony Whereor1 l have affixed my signature.
