WIRE CHAIN.

SPECIFICATION forming part Of Letters Patent N0. 628,189, dated July 4,1899.

Application filed April 3, 1897. Serial No. 630,494. (No model.)

To all whom it may concern:

Be it known that I, FRIEND W. SMITH, J r., a citizen of the United States, and a resident of-Bridgeport, in the county of Fail-field and State of Connecticut, have'invented certain new and useful In] provements'in Wire Chains, of which the following is a specification.

My invention relates to wire chains and the links of which the same are formed; and it [0 consists of certain novel parts and combinations of parts particularly pointed'out in the claims concluding this specification.

In the accompanying drawingslhave shown myinvention applied in the forms which are at present preferred by me; but it ,will be understood that various modifications and changes may be made without departing from the spirit of my invention and without exceeding the scope of my claims.

In the accompanying drawings, Figure 1 is a rear view of a chain embodying my invention. Fig. 2 is a side View of the same, and Fig. 3 a front view thereof. Fig. 4 shows a slight modification of the structure shown in the other figures.

The following is a description of the links and chains illustrated in the accompanying drawings. v 7

Referring to Figs. 1, 2, and 3, it will be seen that each link is composed of a loop I) and eyes 0 c, the loop and eyes being formed of a single piece of wire. This loop may be of any desired form. In Figs. 1, 2, and 3 it is shown as being substantially elliptical in ,5 shape, while in Fig. 4 the sides of the how are more nearly straight. In both cases the side wires of the loop at the eye end converge.

The wires forming the eyes pass, substantially.

parallel to each other, back to the loop and pass through it at that portion thereof where,

as above described, the side wires of the loop converge. The ends are then bent outwardl'y around the side wires of the loop in the form of hooks. In Fig. 3 the extreme ends of the wires are in contact with the side wires, say, about two hundred and forty degrees, whereas in Fig. 4 the ends are in contact with the side wires perhaps one hundred and eighty degrees. This difference in degree, however, is immaterial, the essential point being that in both cases the ends of the wire after forming the eyes pass inside of the converging wires of the. loop and are then hooked around the sides thereof. The length of these ends and the degree to which they are in contact with the side wires and the disposition of the hooks will vary in practice, depending to some extent upon the gage'of wire employed and the size of the links.

The essential feature of a link constructed as described is the passing of the wires forming the eyes first inside the loop between its converging sides before the ends are hooked around the side wires, the result being'that when tensile strain is applied the converging side Wires of the loop pinchthe eye-wires together and resist the tendency of these wires under such conditions to uncurl.

Having thus described my invention, what I claim, and desire to secure by Letters Pat 7o ent, is-- 1. A chain, the links of which are each composed of wire bent to form a loop and eyes, the extreme ends of the wire after forming the eyes passing directly to the inside of the loop and thence bent outwardly to hook about the sides thereof.

I 2. A link for chains composed of wire bent to form a loop and eyes, the extreme ends of the wire aft-er forming the eyes passing directly to the inside of the loop and thence bent outwardly to hook about the sides thereof.

, FRIEND W. SMITH, JR. Witnesses: I

M. WILsoN,

O. J. RATHJEN.
