AUTOMATIC RELEASING DEVICE FOR BURIAL APPARATUS.

SPECIFICATION forming* part 0f Letters Patent No. 710,406, dated October '7, 1902. Application filed .Tune 26, 1900. Serial No. 21,694. (No modela To a/ZZ whom, it 71mg concern,.-

Be it known that I, WILLIAM L. BARTH, a citizen of the United States, residing at the city of Battlecreek, in the'county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Automatic Releasing Devices for Burial Apparatus, of which the following is a specification.

This invention relates to improvements in detachable fastenings for the bands or cords of burial apparatus. It is intended more particularly for such detachable fastenings in use with a machine for the purpose of lowering coflins or caskets; but it may be used in connection with straps or cords where a coffin or casket is lowered by hand.

The object of this invention is to provide a con venient, simple, strong, and safe .automatically detachable fastening device for the bands or cords used to lower cofflns or caskets into a grave.

A further object is to provide such a device the members of which shall be very securely coupled until the cords or straps are entirely jslack and the fastening has dropped down away from the bottom of the casket or other load. t

A still further object is to provide an improved latch-lever connection which shall re- .main securely coupled until the load is wholly released.

Still further objects will appear in the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in this specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is fully illustrated in the accompanying drawings, forminga part of this specification, in which- Figure lis a detail plan view of my improved fastening as it appears when locked together. Fig. 2 is a detail sectional view of the same, taken on line 2 2 of Fig. l, it being shown in operative position in connection with a box or casket. Fig. 3 is a side elevation view of the same after the load has been` relieved and the cords or straps slackened, showing` the position of the part-s when they automatically release.

In the drawings the sectional view is taken Ilooking in the direction of the little arrows at the end of the section-line, and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, D D' represent lowering straps or cords. To the strap D' is secured a suitable loop A, the front or engaging portion of which is at right angles to the direction of the strap. The said engaging portion is preferably narrower than the strap, particularly if it is a broad strap, as is illustrated in Fig. l. To the opposite strap D is secured the opposite member B of the fastener, the engaging portion B of which is formed something like a hook, with a downwardly and forwardly eX- tending portion B. A small pivoted latch C is provided for closing up on the engaging portion of the loop A. A attened lever portion C of the latch extends upwardly and rearwardly to contact with the under side of the box or coffin E to hold the loop A securely in position. This latch is pivoted at e on the main hook portion B. It will thus be seen that when the hook is in the operative position it is, in eect, a mousing-hook, the mousing being held automatically in position bythe action of the'load on the pivoted latch no matter what the load may be.

It will be observed in operation that when the load is lowered to a suitable support and a space left beneath for my improved fastening to drop down that as the latch is light the loop A will drop out of the hook B' and then can be easily. withdrawn under the finger portion B", which, as I have before stated, points downwardly and forwardly for this purpose. It will thus be seen that when the load is lowered my improved fastening will become automatically disengaged, when each portion can be withdrawn, the rounded por tion of the latch permitting it to move a little backward, when it will drop down against the shank of the hook B and will not engage any part where it may be passing. I desire to remark in this connection that my improved fastening device can be greatly varied in its form without departing from my invention. A di'erent form of latch might be provided, and other variations will be apparent to those skilled in the art to which my invention pertains.

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

1. In an automatic releasing device, the combination of a loop member A; an opposite member B having a hook-shaped engaging portion and a downwardlyand forwardly projecting portion beyond said engaging portion to hold it in an elevated position; and a pivoted latch adapted to contact with the load for retaining said loop in position, as specified.

2. In an automatic releasing device, the combination of a loop; a member having a downwardly-projecting engaging portion eX- te'ndcd into a downwardly and forwardly projecting portion; and means of retaining the loop in engagement with said engaging portion, for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.

WILLIAM L. BARTH. [L 5.]
