LINK FOR CHAIN BELTS. APPLICATION FILED MAR.22, 1920.

1507/6 ntor UNITED STATES PATENT OFFICE.
RAYMOND W. DULL, OF LA GRANGE, ILLINOIS, ASSIGNOR TO LINK BELT COMPANY OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
LINK FOR CHAIN BELTS.
Application-filed March 22, 1920.
To all whom it may concern.
Be it known that I, RAYMOND W. DULL, a citizen of the United States, residing at La Grange, in the county of Cook and State 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; and to form said parts so as to reduce the waste of material in stamping the link from the blank to a minimum.
Other objects and advantages not herein necessary to be mentioned will be found characteristic of my invention.
It will be understood 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. The pintle end may be made as suggested by its parts beingbent in either direction.
The invention illustrated-in the accompanying drawings, wherein:
B igure 1 is a view of a blank from which such link may be formed;
Fig. 2 is a plan View of a finished link; and
Fig. 3 is a side elevation of a section of a chain composed of such links.
Like parts are indicated by the same letters in all the figures.
A is the blank, the body of which is sub stantially rectangular in form with the projection B at one end. C indicates the inner part of the link which is stamped out along the lines indicated by C to form the hook. The finished link comprises the side bars D, D, the end bars E, 'F, and the two portions C, B. The end bar E is bent to one side ofthe body of the link so as to form a portion of the hook and the hook portion C is then bent from the inner edge of the side bar E down and around, up wardly and inwardly toward the outer edge of the side bar so as to form a hook. The pintle end is formed by bending the side Specification of Letters Patent.
Patented Oct. 25, 1921.
Serial No. 367,654.
bars at a distance from the end of the hole left by stamping out the part C and then bending the end bar F around and bending the part B around between the side bars D, D, until its end edge is in substantial contact with the other edge oi the side bar F These bends can take place in either direction, but I prefer to have them so that the approaching or opposed edges of the parts which form the two tubular ends lie on the same side of the body of the link.
It will of course be observed that some of the features of my invention can be obtained without using the others.
It will be understood of course that the Size and proportions of the several parts could be greatly varied without departing from the spirit of my invention and I do not wish therefore to be limited to the pre cise relations shown in the drawings.
