WELDLESS CHAIN.
Specification of Letters Patent.
Patented June 11, 1907.
Application liiled OGOber 19, 1906. Serial No. 339,702.
"To aJ-Z whom it muy concern.-
Be it known that I, STEFAN Kiss VON EosEGHY, a subject of the King of Hungary, residing at Vienna, Empire of Austria-Hunary, have invented certain new and useful mprovements in VVeldless Chains; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same. This invention relates to weldless chains -composed of linkseach of which consists of two eyes arranged at right angles' to each other.
oifer the advantage that the links are considerably shorter than is the case in known chains of this class.y
In the accompanyin drawing Figure 11 shows by way 'of examp e a chain in accordance with the present invention. Each link of the chain consists of two eyes 3 and 5, such eyes being at right angles to each other, c osed in themselves and rigidly connected with each other. Thesaid eyes are approximately of the same size and shape. The longest inner diameter of any eye is shorter than the shortest outer diameter of any eye. As the possibility of the existence of such chains is not obvious, the way in which they can be'made will now be described it being understood that this process does not form part of the present invention but constitutes the subject matter of applicants prior application of June 2nd, 1906, Ser. No. 319,954 now Patent 4844,006 dated February 12, 1907.
In the accompanying drawing Fig. 1 is a side elevation and Fig. l2 a central transverse section of a blank for making a chain link according to this invention. Fig. 3 is a plan View and Fig. 4 is a transverse section of an end of the blank. Fi 5 is a vertical section of the upper die and 'g. 6 is a vertical section of the lower die for operating upon the blank, Fig. 7 is a transverse section of the lower die, Fig. 8 shows in side elevation, Fig.
ated upon by the dies shown in Figs. 5, 6 and 7, Fig. 11 shows a part of a chain made by the present process.
The blanks from which chain links are made by the present process consist of straight rods, the central portion 1 of which has the transverse section of the links to be made while the ends are thickened. The blank is threaded into an eye 3 of a link already made as shown in Fig. 3 and is then put together with the said eye into a press, the upper die of which is shown in Fig. 5, while the lower die is shown in Figs. 6 and 7, the blank on being placed into the press occupies, the position shown in dotted lines in Fig. 8. By the action of these dies the central portion 1 of therblank is bent at its yends and the end portions 2 are shaped to two equal rings 4 situated in one plane and ilat on one side as shown in Fig. S in full lines and in Figs. 9 and 10. Then the central portion 1 of the blank is so bent in any suitable manner so that it forms an eye 5 and the rings 4 at its ends are laid upon each other with their fiat sides fitting each other exactly, the two rings 4 thus form an eye 3 crossing the eye 5 I in Fig. 11. The fresh link is then completed and a blankcanv be threaded through its eye 3 formed by the rings 4 from which blank the next link may be formed as above described. A y 'The length and thickness of the end portions 2 of the blank must be so proportioned that they offer the quantity of material required for forming the rings 4 and these rings must be of suflicient size for permitting the thickened end portions of the blank to be lthreaded through them. The object of thickening the end portions 2 of the blank (as compared with the central portion 1)4 is to favorably arrange the material for forming the rings 4. As in this improved process only the thickened ends 2 of the blank have to be threaded through kthe eyes 3 the opening of the latter may be much smaller than.
is the case with the methods heretofore used for making chains of thisA class, in which old methods through the eye 3 of a completed link, a ring 4 constituting one half ot' the eye. 3 of the next link had to be passed.
