6, MARZO I LINK FOR CREEPER CHAINS Filed May 23, 1967 FIG-1 FIG-2 INVENTOR BY 4 F1063 ATTORNEY United States Patent LINK FOR CREEPER CHAINS Victor Milian Marzo, Chirivella, Valencia, Spain, assignor to Industrias Yuk, S.L., Chirivella, Spain, a corporation of Spain Filed May 23, 1967, Ser. No. 640,678 Claims priority, application Spain, June 14, 1966, 122,609 Int. Cl. F16g 13/06 US. Cl. 59-90 3 Claims ABSTRACT OF THE DISCLOSURE The links for bottle creeper chains which are known at present are made up by means of a flatbar from whose opposite edges there project curved fins which act as setting hinges between links. This type of chain sufiers from serious problems because those curved fins which act as setting hinges during its work tend to unfold, with the resulting uncoupling of the links which make up the chains.

The patent of invention which is applied for solves those problems by means of a simple and economical organisation. Its aim is to see that the curved fins of the links cannot unfold during the working of the chain, thus preventing the uncoupling between links.

For this purpose, the link for creeper chains which is applied for is characterised because, being of the type which is made up by means of a flatbar from whose opposite edges there project curved fins which act as setting hinges between links, it presents said fins anchored on the flatbar itself which makes up the link, so that on the end of each fin opposite that on which it is joined to the edge of the flatbar, it passes through the body of the latter, remaining substantially riveted on same.

A page of drawings has been drawn up by way of explanation and without any restrictive nature whatsoever, in order to aid the comprehension of the idea stated. It illustrates this specification as an example of embodiment of the object with which we are concerned.

FIGURE 1 otters us a bottom view of the link with which we are concerned. As can be seen, it is of the type which is made up by means of a flatbar 1 from Whose opposite edges there project curved fins 2 which act as setting hinges between links.

FIG. 2 is a vertical cross sectional view taken through line 2-2 of FIG. 1 and looking in the direction of the arrows.

Now then, a real innovation is established by the fact that said fins 2 are anchored on the flatbar 1 itself which makes up the link so that the end of each fin 2 opposite that on which it is joined to the edge of the flatbar passes through the body of the latter, remaining substantially riveted on same.

For this, the ends of the mentioned fins 2 are provided with extensions 3, which are precisely those which pass through the flatbar 1 itself, which has windows 4 for this purpose.

FIGURE 2 otters us a cross section of the link. As can be seen, the flatbar 1 presents curved fins 2 which act as setting hinges between links. Observe that the end of each fin opposite that on which it is joined to the edge of the flatbar 1 passes through the body of the latter, remaining substantially riveted on same by 5.

In the industrial sphere, the embodiment described offers a decisive series of advantages. In fact, the fact of anchoring the fins on the flatbar itself in such a way that their ends pass through the body of the latter is due to a simplified manufacturing process which does not increase the habitual production costs and which allows one to expend these tools on the market at attainable prices.

If we also consider the fact that said embodiment prevents uncoupling between links, as the fins always remain in the same position, it is evident that the patent of invention applied for acquires a singular practical utility because of the new benefit or effect which it contributes to the function for which it is designed.

In short, the patent of invention which is applied for will correspond to the following claims.

I claim:

1. A link for an articulated chain comprising:

a flat bar including opposed edges,

each of said edges including a reverse-bend portion forming an integral hinge-sleeve at one side of said bar for connection to another link of a chain,

said reverse-bend portions including a terminal end portion connected to said bar,

said bar including a portion forming an aperture spaced inwardly of said edges,

said terminal end portions of said sleeve extending through a respective aperture and being fixedly secured therein.

2. The structure as claimed in claim 1 in which the terminal end portions of said sleeves are enlarged in said lrjespective apertures to integrally rivet said sleeves to said 3. The structure as claimed in claim 1 in which said link includes two sleeves extending from one edge of said bar, and one linkextending from the other edge of said bar, said two sleeves being spaced from each other a distance sufiicient to receive between.
