Application led December 13, 1915, Serial No.' 66,530. Renewed Septcmberv22, 1917. Serial No. 192,830.

To all whom t may concern Be it known that I, fammi B. Soi-mieren, (whose post-office address is 90 Perry street,) a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Detachable Links; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in detachable links, or the like, and more particularly to that type of such links, com monly termed as lap-links, and which are adapted for use as a coupling element between adjacent chain ends, or other similar devices it is desired to connect.

An object of the invention is tol provide a construction of this character, in which the contour of the same, when in closed or operative position, is continuous and uninterrupted, by indentations or protuberances or the like, and one which is adapted for easy and rapid application for the purpose mentioned.

With this and other objects in View, the invention resides in the certain new and novel construction, which is to be hereinafter more fully described, set forth in the appended claims, and illustrated in the accompanying drawing, in which,

Figure l is a top plan view of the preferred embodiment of the invention,

Fig. 2 is a top plan of the same in open position,

Fig. 3 is' a side elevation, and

Fig. 4 is a vertical longitudinal section on the line L /l of Fig. 1.

Reference being had to the accompanying drawing, in which similar characters of reference designate corresponding parts in the several views thereof, the invention comprises a pair of superposed link elements '-l0- and -ll-, each formed to provide oppositely disposed, substantially J-shaped, hook elements -l2-, the members -13-, of which, being connected in spaced, longitudinally offset, parallel relation, by means of a pivot-plate -l4l-, the free endsl5, of the members -13-, projecting beyond the edges of the pivot-plate 14.* and in opposite directions therefrom, being beveled, as at -16-, while the free ends -l7 of the hook elements -12-, ternmate in a plane with the free ends '-15--, of the members l3-, and are also beveled, as at 18-.

On the lopposed faces of the link elements l0h and -ll-, at points thereon directly opposite the openings betweenv the ends -15- and -l7-, of the members 1S- and the hook elements -12-, respectively, and obliquely thereof with respect to one another, and rising therefrom, are abutments -l9-, each having its opposite end walls beveled, as at --20-, to correspond to the bevels 1G- and -18, of the said adjacent ends -15- and -17-.

The link elements 10- and -11- are, when properly superposed, pivotally movable with respect to each other on a pivot pin -2l-, which is passed through alining openings formedin the pivot-plates -14-, and secured therein in any desired manner.

From the foregoing, it will be readily apparent that the invention provides for an inexpensive, compact and efficient device of the character mentioned, the construction of which admits of the contours of the opposed faces of the link elements contacting throughout the area thereof, whereby to distribute the strain, to which the device may be subjected equally to both of the elements, the beveled contacting surfaces tending to reduce the strain brought to bear on the pivot pin, and one in which the outer contour of the assembled elements is continuous and uninterrupted, such as is not usual with the ordinary or similar type of such device.

Having thus fully described the invention, what is claimed, is

l. A device of the character described comprising a pair of superposed link elements pivotally supported at their centers,y each being formed to provide a pair of oppositely disposed J-shaped hook members integrally connected intermediate their ends by a transverse plate.

2. A device of the character described comprising a pair of substantially oval shaped link elements, each being formed to provide a pair of Aoppositely disposed hook members integral with a transverse plate, and an inset pin pivotally connecting said plates.

3. Adevice of the character described comprising a pair of elongated link-elements, each having openings disposed at opposite sides of the longitudinal center thereof, and obliquely with respect to each other, alining transverse bars centrally disposed of each link-element, a pivot pin connectingy said transverse bars, and abutments carried by each link-e1ement and adapted to be engaged by the Walls of said openings.

4. A device of the character described comprising avlpair oi' elongated link-ele ments each foi-med tol provide oppositely disposed J-shapedpmernbers having bevel Walled openings disposed at opposite sides of the longitudinal center thereof, and obliquely with respecty to eachother, eentrally disposed alining transverse bars conopenings.

In testimony whereof I affix my signature, 1n presence o a Witness.
