Be itknown that I, WILiiAM. "Him DOItN, a 01 zen of the United Statesfresidvinggat Davenport, in the county.

State of Iowa. have invented certain new. and; useful Improvements in SkidChains,

of Scott,

' of which the following s a specification.

' wheels an d then Generically my invention} relates to :im--

provements inconstructionand operation ofskid. chains meansfor connecting and more specifically to .the the ends of the sides of such chains. Among thefobjects of my in-,

vention are to produce a 'constructionof thrcharacter stated which can be applied to automobile wheels without the necessity of placing backward until the chains can befastened;

' to produce-a device of the kind istated in' which a floating cross chain willautomatically moveinto its proper position with the advancingmovementof the wheel; topro duce a. device of the .kindistated .in which av floating cross chain'will automatically move into its ,proper position;- and V be automatically locked-therein; to; provide animfurther objects,

. parts illustrated the accompanyingdrawconnecting bar for the v able for use with proved locking member for securing the ends of thefside chains together;.-to-prov1de inc a structure ofthe character indicated an improved hook and locking means and such advantages and capabilities aswill later more fully appear and. as are inherent in the {construction .disclosed.

. .My{invent1on further resides in the com-' bination, construction and arrangement of ing and, whileI'have 'shown ,therei re-. ferred embodiment of my inventionpI desire the same to be understood as illustratiye only and not as limiting said'invention. i

In the drawing annexed; hereto and forming a part'he're'of, Fig. 1 I

ends of one of the side chains of a'skid chain; Fig. 2 is a plan view of the structure shown in Fig. 1; Fig. 3 is a fragmentary plan view similar to Fig.

, 2 but showing the end link of a cross chain just about to drop into the locking notch which .holds said cross chain in properly ad-. justed position; Fig. 4 is a side view showing the link completely received by the holding notch; Fig. 5 is a transverse section approximately along theplane indicated by the line 55, Fig. 1; Fig. 6 is a view of one form of end link which 1S suitthe cross chains; Fig. 7 is the 'chalns on the ground or on the" movlng the carv forward. or

- tac'hmnt of the i links is a side view of the erspective a view similar to Fig.4 but 4 inclusive; and Fig. 8 is, a "fragmentary plan view of apalr of. side barswith chains attached. i

Referring'niore in detail to. thesefdrawings, numeral 1 designates ,a connecting link orsidebar designed for use uponjthe right. side of, agwheel. The correspondinglink on the same shape except that the. eye A rear endwill be' offset to the opposite side of thelinkandthechain receivingslot and hook at thc opposite end. will also be re versed, to face in the opposite I direction. The laterally therein forthe reception of an end link 1 of:one of the side chains as will bezreadily understoodj At the opposite side of the link 1 is a hook 5 adapted to receive alink of the other end of the side chain. A. member 6, U-shaped:in 'cross-section, is pivoted at 7 to the hooko' and is provided with finger pieces 8 whereby itmay be manipulated-to open and closed position. Y 1 [An ordinary cross ends with suitable links 9., suclnfor example; as the one shownin Fig. 6 which has the eye 10 and the hook 11 arranged approximately @590 degrees to each other, inorder that the links of the chainmaylie fiat j during operation. Of course j, it is underon the ground stood that the shape and structure of the link 9 mustxvary according to the shape and structure "Q ftlle cross; chainfused, the one shownbeingparticularly adapted, for a coin mon chainknow on themarket. When these links 9 are flppli, d to the ends of this chain;

I showing the-use of api'voted end hook instead .of an end h'ook rigid with the sidebar as, shownin Figs. "1 to.

bar forum left sideof the wheel wouldilieof I fatthfef .chainis providedatits ,the hook's 11 are closed up to prevent-the de i a from the ends of the cross chain. Slot 12 opens through the upper part of the link 1 into a slot 13 as shown. This device is so constructed that points 14 and 15 project on opposite sides of the slot 12 shims thepurpose of these projecting points.

From this figure it will be seen that the link 9, when it slides downthe side link 1, will engage the point 15 and will be prevented from going further. The outer side of the loop 10 will'swing around past the point 14 and the link will then drop through the notch or slot 12 into the slot 13 and will be held therein by the projecting points 14. and 15, asv will be evident from Figs. 4 and 7.

as shown most clearly in Fig. 2. Fig. 3'

The side bars or links 1 are preferably substantially flat on the side toward the tire, are broad as indicated at 16, across thetop edge, and are preferably hollow ground or substantially flat upon the outside as 1nd1- cated at 17, being narrow at the bottom.

As indicated in Fig. the hook 5 is d 1spensed with and the loose hook 18 is pivotally connected as at 19 to the end of the side bar 1. This latter is suitably enlarged as shown at 20 and slotted as indicated at 21 for the reception of the hook 18. This latter carries a suitable latch element 6 as in the previously described construction.

In use, the chains are placed over the top of the tires with the ends carrying my im- .provement at the rear side of the wheel,

the vacant ends of the side chains being at the front, as will be understood. The floating cross chainswill be at the rear ends of the side bars 1, as shown in Fig. '1 and the hooks 5 or 18 can then be connected to the free ends of the side chains, the latches 6 being closed, as will be readily understood. Having thus applied all of the chains, the driver gets into his car and starts up as usual. As the wheels roll forward and the side bars 1 rise toward the position indicated in Fig. 41, the cross chains slide clownwardly, carrying the links 9 toward the slots 12. When one side of the link 9 strikes the abutment 15 the link swings around past the point 14 and drops into the notch 12. Having once been received in the slot 13 the points 14 and 15 prevent accidental disconnection of the link 9 which is bound to remain always within the slot 13. It. will thus be understood that the cross chain automatically seats itself in its proper place and prevents undue slack in the side chains which sometimes results when the cross chain is missing. It will also be understood that, when the car is moving forwardly or backwardly, the cross chain must necessarily remain in its proper position, as is not true when the cross chains are pulled into place and held there by gravity alone or by means of springs.

Having now described my invention, I claim:

1. In a skid chain, means rendering it possible to attach the chain to a wheel, co1nprising a pair of bars for connecting the ends of the side chains, in combination With a floating cross chain slidable on the bars, said bars having longitudinally arranged slots at one end whereby the ends of the cross chain are received and held in proper operative position during the normal operation of the wheel.

2. In a structure of the character described, a pair of spaced side chains, cross chains spaced at intervals along the side chains, bars connecting the ends of the side chains, said bars each having adjacent one end a diagonally arranged slot for the reception of a cross chain, and a cross chain having its ends slidable on the bars and receivable in the slots.

3. In a skid chain having a side chain, a curved bar for connecting the ends of the side chain, said bar having in its upper surface a diagonal slot for the reception of a link of a cross-chain, a longitudinally arranged slot within the bar and connected to the diagonal slot, and a cross-chain having a link surrounding the curved bar, slidable thereon, and receivable in the slots.

4. In a skid chain having a side chain, a curved bar for connecting the ends of the side chain, said bar having adjacent one end a diagonal slot for the reception and holding of a cross chain, and a cross chain having an end link slidable on the curved bar and receivable in the said slot.

5. In a skid chain having a pair of side chains, bars for connecting the ends of the respective side chains, said bars each having adjacent one end locking means for the reception and holding of a cross chain, a cross chain connecting said bars and having a link at each end slidable. on the bars, said locking means having an opening therein requiring the end link of the cross chain to turn diagonally of the bar to enter the locking means.

In witness whereof, I hereunto subscribe my name to this specification.

WM. P. HAGEDORN.
