LINK FOR CHAIN-BELTS.

Application filed March 22, 1920. Serial No. 367,655.

To all whom it may concern:

Be it known that I, RAYMOND W. DULL,

a citizen of the United States, residin at aa Grange, in the county of Cook and l tate of Illinois, have invented a certain new and useful Improvement in Links for Chain- Belts, of which the following is a specification.

'My invention relates to integral links for chain belts formed from sheet metal of substantially uniform thickness.

Some of the objects of my invention are to provide a wide, supporting base for the hook; substantially tubular, closely fitting, interlocking pintle and hook ends; to form such'pintle' and hook ends so that the edges of their parts may be on the upper side of the link; a'nd to so form the end forming parts as to diminish the waste of material.

Other objects and advantages not herein necessary to mention will be found charac teristics of my invention.

It will be'understo'od that I do not wish to be limited to the particular proportions of parts here shown as they may be greatly varied without departing from the spirit of my invention. The hook end is shown in the preferred form but it can be made in any one of a variety of ways.

he invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a view of ablank;

Fig. 2 is a plan view of a complete link made from such blank;

Fig. 3 is a side elevation of a chain section made from such links.

Like parts are indicated by the same letters in all the figures.

A, A are side bars on opposite sides of the opening B. C and D are end bars; E and F, portions which are intended to be cut and upwardly and outwardly bent to form parts of the two ends and G is a hook portion. If a short link is desired, the hole can be suppressed and if desired, the length of the projection F could more nearly equal the depth of the space between the two free end of the sidebars A, A so that successive links could be cut from a sheet of metal with a minimum waste of material. This latter isone of the important features of this invention.

Specification of Letters iacent.

Patented Nov. 8, 1921.

It will of course be observed that some of the features of my invention can be obtamed without using the others.
