JOEL-M. SCOTT, OF ETOILE, KENTUCKY.
LAP-LINK.
Specification of Letters Patent.
Patented. March 30, 1909.
Application filed July 15, 1907. Serial No. 383,940.
To all whom it may concern:
Be it known that I, JOEL M. Soon, a citizen of the United States, residing at Etoile, in the county of Barren and State of Kentucky, have invented a new and useful Lap- Link, of which the following is a specification.
Objects of this invention are to provide a lap link particularly adapted for emergency use to secure together the ends of a disrupted chain, either temporarily or permanently; to provide a convenient, compact and strong de vice for this purpose which is portable, easily applied where needed, and easily removed to replace it with permanent links; to provide a device which is, in its assembled form, practically a contiguous unit stronger than the chain-links to which it is applied, and one in which spreading of the parts is absolutely prevented; and to provide a device which is capable of being used not only as a connecting device for disrupted chains, but which is admirably suited for use in connection with draft appliances of any description.
The accompanying drawings illustrate the invention.
Figure 1 is a perspective view showing the position of the lap-link for receiving the ends of the chain; Fig. 2, a side elevation showing the end links of a chain engaged by said lap-link; Fig. 3, a plan view; Fig. l, a sec tion substantially on line indicated by m, Fig. 2; the end links being shown in full lines. Fig. 5, a side elevation of the outside link; and Fig. 6, a side elevation of the inside link.
1 is a link provided with a latch-chamber 2.
l is a lug or closure provided on the inside of the link 1.
.3 is another link member within said link 1 and provided with a latch-chamber 6 to accommodate the lug l, and with a lug 7 arranged to fit into the latch-chamber of the link 1. 8 designates rivets for pivotally securing the said link 5 within the link 1.
The walls 9 of the latch- chamber 2 and 6 are divergent to insure a movement in but one direction.
In manufacturing the device, the links are preferably drop-forged, and at the same time provided with the latch-chambers and lugs, though the lugs may be placed on the links after the stamping operation.
The links may be made of any suitable material as steel,forgcd or cast,malleable or other iron, or steel or other wire, as may be found most expedient to the manufacturer, and best adapted for the use for which it is intended.
I claim:
An outside link provided with a latchchamber at one side and a closure for a latchchamber directly opposite said latch-chamber, said latch-chambers and closure being at one side of the transverse center, pivots at said transverse center and projecting inardly; an inside link mounted upon said pivots and provided with a latch-chamber to receive the closure of the outside link and provided with a closure for the latch-chamber of the outside link. i In testimony whereof, I have hereunto set my hand at Los Angeles, California this 3rd day of July 1907.
