HOOK r03 use WITH CHAINS.

' Application filed April 18,

for spoked vehicle wheels, so that such chains can be conveniently applied or removed and when applied shall be retained securely in place. This and other objects of my invention, will be more fully made apparent in the following specification and claims taken in connection with the accompanying drawings in which I have disclosed two specific embodiments of the invention. It will be understood that modifications may be made within the scope of my invention as stated in the claims.

' Referring to the drawings, 7 v

Figure 1 isan elevation of my improved hook in engagement with a chain link;

Fig. 2 is a side elevation of the same hook; 1

Fig. 3 is an end elevation looking in the direction of the arrow 3 in Fig. 2;

F i' 4 is a section t ken on the line 4-4: of Flg. 2, and l Fi 5 is an elevation of a modified form in w 'ch my inventive idea may be embodied. Y

Referring to'the modification shown in Figs. 1 to 4, the hook has an eye 11 at one end 16 adapted to be permanently engaged by the end link of a chain. Adjacent to the eye 11 is a shoulder 12 with the part 13 overhanging the .ti 1501 the hook. Connected with'the en portion 16 is the .proxi mal portion comprising the neck 17 and'the part 21; then comes" the-apex 23, beyond which is the'distal portion comprising the l parts 19, 18, andth'e tip .15. The projecting abutment 20- overhangs the link 24: when I 'the link 24:

the hook and thelink' are fully assembled,

n -at this time in the notch,

or socket'22."

Betweenitheti :15 and the face 13 of the i shoulder'12; is 't e opening to receivethe link in assemblin the chain withv the link. Extending from t opening is a reversely Specification of Letters Patent.

curved or S-shaped passage 14 which termlnates at the socket 22.

The abutment 20 is of considerable width as shown in Fig. 1 so that an lar movement of the chain link 24 is hmited relatively to the hook about an axis perpendicular to the plane of the drawing. The abutment '20 also aids materially in keeping the link 24 securely engaged by the hook.

- The passage 14; is reversely curved as shown, in order that the linkmust be turned through a considerable angle first one way and then the other way in order to remove it from the hook. This will be apparent Patented May 11, 1920.

from a consideration of Fig. 2. To remove the link 24: it would have to be turned clockwise to bring it to the position .24 and then counter-clockwise to remove it entirely from the tip 15 of the hook." It would be extremely unlikely that such movements could be effected accidentally so that the security of engagement of the hook with the chain will be assured. It is to be noticed in this connection that the channel 14 is of approximately uniform width and only enough wider than the thickness of the chain stock to provide proper clearance.

The line a-b drawn so as to touch the parts 19-and 12 of the hookliesoutside the j tip part 15 as shown in Fig. '2'.' Accordingly, the tip 15 will be protected from a blow delivered by any large object, which will be received at 12 or-19 or at both points together, but not on the tip 15.

. To a very great extent this will prevent the tip 15 from being bent. If a very heavy blow is delivered against the part 19, or a suiiiciently heavy' blow by a small object against the tip 15, the only efiect will be to close the passage 14 and lock the hook in engagement with the chain; evidently so far as this involves any failure of the apparatus 'it will be on the side of safety.

Referring to the modification shown in Fig. 5; this is made of a uniform size stock steel rod 'bent'to the'shapel's hownin the drawing. I The reference characters primed.

have-been applied in ;a manner to correspondto Figs. -1 to 4... Thepassageili' is of. substantially uniform width; enough greaterthan the thickness of the .chain stock ing'member- 20' performs the'same ction a the e m ed element in Fig. 2 in hinderin the escape of the hook from the chain lin with which it may be in engagement.

I claim:

1. A book having a slot to receive the linkof an anti-skid device to be secured, and a transversely wide projection projecting into said slot to cause said link to be at substantially right angles to the plane of the hook passing through the opening in said link. '2. A book for an anti-skid device having a base portion and a proximal portion and a tip portion extending therefrom, said tip portion being formed by reverse curves 23, 19, 18 and 15 connected end to end substantially in the form of an 5 so as to tip the link in opposite directions as it passes along said tip.

3. Aflhook adapted to cooperate with the links ofzan anti-skid device for vehicle wheels, comprising a base portion and a tip portion extending therefrom, and providing reversely curved surfaces spaced relatively to the link surfaces to tip said link'first in one direction and then in another as said link passes along said tip portion.

4. A hook adapted to cooperate links of an anti-skid device for vehicle wheels, comprising a base and a proximal portion and a tip portion extendin therefrom, said tip portion being fo'rme by reverse curves connected end to'end substantially in the form of an S and being of only slightly less thickness than the Width of the opening in said link.

with the 5. A hookadapted to cooperate with the links of an anti-skid device for vehicle wheels, comprising a base and a proximal portion and a tip portion extending therefro'm, said tip portion being formed by reverse curves connected end to end substantially in the form of 'an S and being spaced from said base and proximal portions by a reversely curved slot.

r 6. A hook having a base and-a curved portion with parts proximal to and distal from said base, an abutment projecting across from the proximal part toward the distal part said hook being adapted to cooperate with a link engaged thereby and of stock substantially filling the space between said abutment and the apex, said abutment being transversely wider than the apex part of the hook.

7. A hook having a base and a curved portion with parts proximal to 'and distal from said base, the distal part being curved relatively to theproximal part so as to be convex toward the proximal part and an abutment projecting across from the proxi-, mal part toward the distal part near the apex so as to form a reversely curved pasabutment on one side and the distal part on the other side said hook being adapted to cooperate with a chain of links each having an opening slightly greater than the thickness of the distal part of the hook.
