NONSKID CROSS-CHAIN:HO'II'I'L.

i Application filed September My inventionrelates to nonskid chains and particularly to the hooks used in connecting the cross chains to the side chains.

It is well known that\the cross chains are subjected to severe wear and that'the side chains will outwear many sets of cross chains. It is therefore usual and economical to replace the cross chains when they become worn and broken; but this operation, with the present type of connecting hook,is difficult and tedious, requiring some means for bending open the old hooks to remove them and means for clenching the new books.

With this in View, one of the objects of my invention is to providea device of this character which can be readily attached and detached from both the side andcross chain without the use of tools, and which cannot be accidentally detached from either during normal use.

Another object of my invention is to provide a device of this character which may be easily and cheaply constructed and which will eliminate the present necessity of supplying the consumer with replacement cross chains equipped with hooks.

These and other objects and advantages will appear as the description is read in connection with the accompanying drawing in which Fig. 1 is a fragmentary plan view of a nonskid chain illustrating my connection hook;

Fig.2 is a front elevation view of my hook;

Fig. 8 is a back elevation view of my hook;

Fig. 4 is a bottom view;

Fig. 5 is a side elevation view showing the bill of the hook sprung outwardly as the connection to the side chain is being made; and

Fig. 6 is a plan view showing the manner in which the hook is attached to the cross chain.

Similar numerals refer to similar parts throughout the several views.

My invention broadly contemplates a resilient connecting means that may be merely snapped or sprung into place, as distinguished from the hooks now in use which must be bent and rebent in making a connection; and it further contemplates the provision of certain means whereby the possibility of accidental disconnection is minimized.

In its preferred form, indicated generally serpentine to form the loop, 7 The ends,

6, 1923. Serial No. 661,202.

by the numeral, 3, my hook comprises a loop, 5, adapted to engage a cross chain link, 2; a resilient hook portion forming a loop, 7, adapted to receive aside chain link, 1; and a projection, 4, intermediate the loops, forming a closure for loop, 7.

In fabricating my deviceI prefer to use round stock of such diameter that when made up substantially as shown, it may be readily sprung to make the necessary con nections. I prefer to use steel as a material, bending it first to the desired configuration, and then imparting the necessary resiliency by tempering. Other materials, however, having the necessary strength and possessing, or capable of acquiring, the proper elasticity, may be used.

In making my hook, the projection, 4, may first be formed at about the one-third point in the length of stock selected. This may be easily done by bending the stock 360 degrees about a small diameter cylinder to form a serpentine as shown at, 4. The free ends, 6, may then be brought together and the loop, 5, formed in a plane substantially parallel to the axis of the serpentine. The stock, from the free ends, 6, back to the serpentine, isthen pressed together and bent upwardly and over against the top of the 6, which project somewhat beyond the ser-. pentine, are separated, as at 8, by bending them outwardly to facilitate the entrance of the link, 2 (see Fig. 6) and upwardly to facilitate the entrance of the link, 1 (see Fig. 5).

In practice, the hook is first applied to the cross chain by slipping the link, 2, between the ends, 6, as shown in Fig. 6; and the cross chain is then connected to the side chain by springing the link, 1, between the top of the projection, 4, and the ends, 6, as shown in Fig. 5. It will be obvious that the link, 2, having entered loop, 5, the sides, 9 and 10,

of the hook will spring back to their original 6 position as shown in Fig. 1; and the link, 1, having entered loop, 7 the sides, 9 and 10, will spring downwardly against the serpentine, as shown in Figs. 2 and 3, and prevent the accidental detachment of the hook.

While I have illustrated and described its preferred embodiment, it is clear that my invention is not limited to the precise details shown. The projection, 4, for example, may be differently shaped and other changes may ing the jaws of said hooks; saididouble hooks adapted to be sprung apart to allowa cross chain link to pass therehetween, and sprung away from said projection to permit a side chain link to enter the hook.

2. A cross chain hook oi highly resilient material having aloop adapted to receive a link of a cross chain, and portions npstanding from the plane of sald loop cooperating together to form a second normally closed loop adapted to receive a link of a side chain; said upstanding portions adapted to be sprung apart Within the elastic limit thereof to admit ailink of said side chain into the second mentioned loop.

3. A cross chain hook provided with a loop adapted to engage a cross chain link am a loop adapted to engage a side chain link one of said 1003s includin resilient 2 p portions adapted to .be sprung within their elastic limit to pt' 'odueepassagesfor the admission of said links to either loop.
