The invention relates to devices for facilitating the removal of worn or broken cross chains from tire chains, and the substitution of new cross chains, and it is the object. of

the invention to provide a device of this character which is exceptionally simple'and inexpensive, yet will be efiicient, rapid, and

very easy to operate.

With the foregoing in view, the invention resides in the novel subjeotmatter hereinafter described and claimed, the description being supplemented by the, accompanying drawing 7 Fig.1 is a perspective view of the complete device constructed for operation by foot power.

Figs. 2 and 3 are enlarged perspective views showing the use of the device in opening a hook ofa cross chain to permit removal thereof from aside chain.

Figs. 4 and 5 are perspective views showing the manner in which the devlce is used to, close the hook of a cross chain after application thereof to a side chain.

The form of construction herein disclosed has in actual use proven to be very efficient, rapid and generally desirable, for which reasons, the details herein disclosed may be considered as preferred. However, while these details will be hereinafter specifically described, it is to be understood that within the scope of the invention as claimed, variations may be made and moreover, it may be explained that while the device herein disclosed is constructed to be operated by the users foot, provision could be made for actuating it by power.

The numeral 5 designates a standard having supporting legs, said standard being preferably formed in part of two long metal bars 6 whose major portions are disposed in spaced parallel relation and an intermediate comparatively short bar 7 whose upper end is secured by rivets or the like 8 between the intermediate portions of said bars 6. The lower ends of the bars 6 are curved forwardly and outwardly to provide a pair of supporting legs 9 and the bar 7 is rearwardly curved to provide an additional supporting leg, the lowerextremities of all of these bars being preferably given a quarter twist. providing feet 10 to rest upon the ground or upon a floor.

rivets or the like. 12, to complete the stand ard structure, the upper front corner ofthis bar 11 beingprovided with a chisel-like nose 13 and with a sharpened edge 14 extending rearwardly fromthis nose to the rear edge of the bar, these formations being provided for purposes to appear.

Slidably surrounding the bar 11, is a yoke 15 secured by rivets or the like'16 to a vertical shank 17 which slidablyengages the rear edge of said bar 11. The upper end of this shank is provided withaforwardly extending .arm 19 having a downturned front end 2O of'ohisel-like form to slidably engage the front edge of the formation 13, as shown for instance in Figs. 3, 4 and 5, and the lower edge 21 of said arm 18 ,is sharpened for co-action with the edge 14. In the angle between the major-portion of this arm 18 and its downturned end 20, is a stop 22adapted to strike the member 13 to limit the downward movement of'the shank- 17 A rod 23'is shown connected withthe lower end of the shank 17 and with a foot lever 24, the latter being positioned between the legs 9 and fulcrumed at 25 to the bar or leg 7. suitable spring 26 normally raises this foot lever and consequently raises the shank 17 and parts carried thereby to the position of Fig. 1. By depressing the foot lever 24, however, said shank and parts are downwardly moved. 7

"When the device is to be used for spreading a hook H of a worn or broken cross chain C, the hook is engaged with the chisellike members 13 and 20, in the manner shown in Fig. 2 and then the foot lever 24; is depressed, causing said members to effectively open the hook as shown in Fig. 3. so that it may readily be disconnected from the side chain. When the device is to be used for closing the hook of a cross chain, after application thereof to aside chain,the sharpened edges 14 and 21 come into play, as will be clear from Figs. 1 and 5. The hook is engaged with the edge 14 in the manner shown in Fig. 4 or in a reversed position and when lever 24 is depressed, the edge 21 of the arm 18 moves toward said edge .14

thus closing the hook.

It will be seen from the foregoing that the invention is simple and inexpensive, may be easily manufactured and sold at small cost,- and will be efficient and rapid in operation. 011 account of such advantages I V as these, the" details disclosed are preferably followed; Howevenwithin the scope of the invention as claimed, variations may of of said shankja'hd having" a dov'vnturned 'ehis'el l ilz e nieiiiher (Jo-operable with the fiisrnamed' member to open. the hoolt' of a cross chain, and means for downwardlypullii'ig sa id shank.
