DESIGN FOR A BICYCLE-CHAIN LINK.

SPECIFICATION forming part of Design No. 28,196, dated January 18, 1898.

Application filed July 1, 1897. Serial No. 643,159- Term of patent 7 years.

To all whom it may concern.-

Beit known thatI, CLAUDE A. DUNN, acitizen of the United States of America, residing at Den ver,in the county of Arapahoe and State of Colorado, have invented a certain new and original Design for a Bicycle-Chain Link; and I do 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 use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This design has for its object to provide a novel bicycle-chain link which possesses a pcculiar configuration and one that presents a striking and ornamental appearance to the eye.

In the accompanying drawings, Figure 1 is a perspective view of a chain-link embodying my design. Fig. 2 is a longitudinal section of the link shown in Fig. 1.

The leading features of my design consist of a link having at its center abar portion A and at one end a widened head portion. The link from its center portion and at its top and bottom edges broadens to the end D in one direction and toward the end E in the opposite direction by diverging curved portions 0 and terminates in semicircularshaped ends. One end D of the link is of the same thickness as the central portion. At the opposite end E the link is broadened laterally adjacent to the end into a wide head portion, which is about twice the width of the body portion of the link. This broadened head portion is connected to the body portion by a cyma-reversa curve F on each side. The widened head portion is bifurcated into two terminal ends I and I by a slot H. Trans versely across the slot and through the ends of the head portion a. round member K projects. This projection extends laterally a short distance beyond both of the opposite sides of the head portion of the link in enlarged round trunnion portions J, which lay closely against the sides of the head portion of the link. The terminal ends of the trunnion portion of the pin are slightly COHYGXQd. The slot H in the head terminates in a semicircular curve H, which is concentric to the round projecting member K. The opposite or narrow end of the link contains a round hole or perforation slightly larger in diameter than that portion of the round projecting member K that projects across the slot in the head portion. This hole or perforation is arranged at the center of the semicircular curve at the narrow end of the link. This curved terminal end is shaped with a curve similar to the curve in the bottom of the slot in the head portion.

I claim- The design for a link for bicycle-chains as herein shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
