To open the leg it is only necessary to reverse the above described operations.

From the foregoing description, it Will be seen that I have produced a very simple and efiicient table-leg locking device and one that readily permits the leg to be locked securely in both an open and folded position.

What I claim, is

1. In a. locking device for table legs comprising a casing element adapted to be secured to the under side of the top of a table, a leg foldably attached to the table-top, a

-: casting having a head portion and secured thereto and provided With 'a groove in the head portion thereof, a slide mounted Within the casing element and having a pair of lugs, said lugs being arranged to enter the groove in the casting, whereby the leg may be locked in either the open or folded position.

2. In a locking device for table legs comprising a casin element adapted to be secured to the underside of the top of a table, a leg foldably attached to the table-top, a casting having a head portion and secured thereto, and provided with a groove in the head portion thereof, a slide mounted Within the casing element and having a pair of lugs, said lugs being arranged to enter the groove in the casting whereby the leg may be locked in either the open or folded position, means for operating the slide, and a latch for locking the slide.
