DRIVE-CHAIN LINK.

SPECIFICATION forming part of Letters Patent No. 475,705, dated May 24, 1892.

Application filed February 1, 1892- Serial No. 419.864. (No model.)

To all whom it may concern:

Be it known that I, ARTHUR J. REYNOLDS, of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Drive- Chain Links, of which the followingis a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

The object of my invention is to provide a drive-chain link that is of comparatively simple and cheap construction.

To this end my invention consists in the combination of the several parts making up the link as a whole, and in details of such parts, as more particularly hereinafter described, and pointed out in the claim.

Referring to the drawings, Figure l is a plan view of the link as a whole. Fig. 2 is a detail edge view of the same. Fig. 3 is an edge View of the completed link.

In the accompanying drawings, the letter co denotes the link as a whole, I) the pintle-section, and c the knuckle-section of the link, these two sections being formed of separate pieces of metal. The section b is cut from a sheet of metal, an opening I) being formed, leaving a frame-like structure with sufficient metal on one end to be rolled or otherwise formed into the pintle d, that is of cylindrical form, while the other end of the frame forms a flat transverse bar 6, united by side parts 11 to the pintle, all these parts of the frame being integral. The knuckle is formed of a single oblong strip of metal of a Width about equal to and being not greater than 5 the width of the opening I) in the pintle-section and having a knuckle f, formed by rolling up one end of the strip, while the other end is clamped to the bar 6 by folding it down upon and causing it to embrace the bar to a greater or less extent. The folded edge of the strip at f forms a rounded edge suitable for a bearing against the side of the sprocketwheel teeth that project into the opening 1),- When several links are united to formachain. The section b may be made of such length that the part removed to form the opening I) will be of sufficient length to form the strip from which the knuckle-section of the link is made, and when this is done there will be no waste of metal Whatever in making the link.

I claim as my invention The improved drive-chain link composed of the pintle-section b and the knuckle-section 0, the said pintle-section being formed of a piece of flat plate metal with acentral opening, and a pintle d, formed at one end of the section and having a flat bar 6 at the opposite end, the knuckle-section made of a strip of plate metal having one end rolled up to form a knuckle and secured to the pintlesection by the end of the knuckle-section folded down upon the flat bar 6, all substan tially as described.

ARTHUR J. REYNOLDS.
