HARRY EUGENE KELLEY, OF NIAGARA FALLS, ASSIGNOR TO THE ONEIDA COHUI NITY, (LIMITED) OF COMMUNITY, NE\V YORK.

CHAIN-FASTENER.

SPECIFICATION forming part of Letters Patent No. 404,631, dated June 4, 1889.

Application filed November 28, 1888. Serial No. 292,094. (No model.)

To all whom 2125 may concern.-

Be it known that I, HARRY EUGENE KEL- LEY, of Niagara Falls, in the county of N iagara, in the State of New York, have invented new and useful Improvements in Chain-Fastenersof which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention is a specific improvement of the class of chainfasteners which have ahar pivoted intermediate of its length to a bodyplate attached to the end of a chain or strap.

My present invention consists, essentially, of a chain fastener composed of a body- I 5 plate, a bar pivoted to said body-plate, a stop arranged to arrest the movement of the aforesaid bar in one direction, and a coil-spring holding the bar normally resting on the stop; and the invention also consists in certain novel features of the details of the device, as hereinafter fully described, and specifically set forth in the claims.

In the accompanying drawings, Figure 1 is a plan view of a chain-fastener embodying my invention. Fig. 2 is an edge view of the same. Fig. 3 is a transverse section on line 0: 00, Fig. 2. Fig. i is a transverse section on line y 1 Fig. 1. Figs. 5 and (3 are detached plan views of the coupling-bar and disk to which it is pivoted, and Fig. 7 is a plan view of the blank from which the body-plate is formed.

Similar letters of reference indicate corresponding parts.

3 5 A denotes the body-plate of the chain-fastener. Said plate Iform from ablank stamped out of sheet metal, of the shape shown in Fig. '7 of the drawings, the ends of the blank being of the form of annular heads 25 If, each of 1,0 which has a square or other angular perforation 2' at the center. This blankI bend at the center of its length, so as to cause the two.

eye I), and with an elongated notch f in the edge of said eye.

In the eye Z), Iplace an an n ular disk (I, which .is formed with a projection e and provided with a square or angular perforation r, corresponding to the perforations '2' i in the heads 25 t of the bodyplate A. The projection e of the disk is entered into the notch f aforesaid,

and the bar 13, with the disk (I seated in the eye I), is inserted between the heads t 2, and by means of a square or angular pin p, passing through the perforations 1' land '0, the disk is firmly sustained between the aforesaid heads, and the bar B, turning on said disk, is thus pivoted to the body-plate. The projection 6 of the disk serves as a stop which limits the movement of the bar B in one direction by coming in contact with the shoulder at one end of the notch f. The bar Bis held normally in the aforesaid position. by means of a coil-sprin g h, seated in the eyeb and upon the disk (Z, which is thinner than the bar B,

so as to leave room for the reception of the aforesaid spring. One end of this spring is attached to the bar B, and the opposite end is attached to the disk (Z. The spring is wound in such a direction as to hold the bar normally resting on the stop 6.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A chain-fastener consisting of a bodyplate, a bar pivoted to the body-plate, a stop arranged to arrest the movement of the afore- 8 5 said bar in one direction, and a coiled spring holding the bar normally resting on the stop, as set forth.

2. The improved chain-fastener consisting of a body-plate, a bar pivoted to the body- 0 plate and provided with a chamber at its pivot, a stop in position to arrest the movement of the aforesaid bar in one direction, and a coil-spring seated in the aforesaid chamber and holding the bar normally resting on the stop, as set forth.

The combination of the body-plate A, formed with the case A, the bar B, pivoted in said case, a stop arranged to arrest the swinging of the aforesaid bar in one direction, and a coil-spring inclosed in the aforesaid case and holding the bar normally resting on the stop, substantially as described and shown."

4. The combination of the body-plate A, formed with the case A, the disk cl, confined in the said case and provided with the projection e, the bar B, formed with the eye 17, and pivoted thereby on the aforesaid disk, and provided with the elongated notch f for the reception of the projection e, and the coilspring h, seated in the eye I) and connected at opposite ends, respectively, to the bar B
