A Divided and this applicatian led June 20, 123@ Serial No. 462,607.

This invention relates'to tables in Ageneral and particularly to table legs whichflfold beneath thetop ot' the table.

The present invention 'is a division of application liie'rial Noll-381582, lilcd August 9, 1929, new Patent No. 1,860,6lhlay 31, 1932.

The primary object of the inventionV is to provide a table having new and improved folding legs which are automatically locked in position when the legs are extended.

Another object is to provide a table having walls, legswhieh'are locked in position 4when the legs are extended and which may be unlocked when the legs are given a part turn.

vA further object is to provide a folding table'which is provided with inter-engaging means for locking the table legs in extended position and which is provided with means for unlocking the legs when the legs are given a partial turn.

A further object is to provide a table having support to which the table legs are pivotally attached, said legs comprising a'sleeve portion and a leg portion. Spring means are provided for urging the leg portion iny one direction relative to the sleeve portion 'for locking the leg in extended position. Means are also provided for urgingthe leg in an opposite direction when the leg portion is given a partial turn.

A further object is to provide vthe method ol making table legs which consists in insert; ing a spring having a free end leading through the spring, providing a hole in a Closed end of a member through which the free end of the spring extends, tensioning the'r springl by pulling the free end, passing favstening means through the said member to provide a tension on the spring, and finally cutting the free end of the spring and restrictin the spring between fastening means and the closed end of the member.

Yumerous other objects and advantages will appearthroughout the progress of the specification.

The invention comprises in general a table having rails which are made from a single strip of sheet metal. rlhe rails are bent to provide inwardly extending legs which are perpendicular to the vertical plane of the vrails. These legs are arranged below the table .top substantially the same distance as the thickness ot the top. Corner pieces have reduced ends which lit into theopenends of the rails and are fastened thereto sothat the outside of the rails will be flush with the out- Qhe legs comprise a sleeve portion and a leg portion received in the sleeve portion. A spring coneealedinslde of 'the leg portion,

` side ot the corner pieces. rlhe corner pieces i have parallel flanges provided on their bottoms to which legs are plvotally attached.VV

and fastening means extending through the l.

ilanges on the corner pieces and through the sleeve and leg portions confine the spring between the fastening means and the top of the leg portion. The leg portion vis provided .vith'diagonal slots for retracting the nor'- mally projecting' pin or locking memberon the end ol the legl portionv when the leg portion is given a partial turn. A socket'is pro-V J vided in each corner piece to receive this pin when the leg is in extended position. A To fold the legs it is first necessary to give the leg portion a partial turn whichwill bring the pin out of engagement with the socket.

Referring to the drawings, 10 designates generally, a table having rails .11, which are fastened. to corner pieces 12. Legs 13 are pivotally vconnected to the corner pieces 12,

Leiva-91eA l 3 clearl f shown in Figs. G and- 7 to erinit fre .l u 1 P locking and unlocking engagement. r i i f It is-understood, oflcourse, that the sleeve 30 may be iliade-polygonal .instead ofcircu-V lar,.-as shown, and that the `entire vupper end ofthe leg may fit into a corresponding `socket instead of using the smaller conical pin/i3 engageable Witlrtlie smaller socket 4A.

.The legs are Vprovided with .a decorative portion a6', Figsl and 2, suoli` as-luting or knurliiig to decorate the legs .and make the table more attractive-and also. to increase the firmness ofthe grip of; the operator. on the table leg to bring the pin 43 out Vof engage'- ment with itssocket. j g

The iiivention providesa table `leg which is strong and durablein construction,which is efficient in operation, and which Vcanbe readily and economically manufactured. The legs automatically'lock in position when extended andinay be unlocked by giving'a part of the leg apartialturn. Thelegsmay be manufactured at a very low cost and may be, readily manipulated for bringing them into locked o r unlocked position.` V'lhemethod of constructing the legs, inserting the springs in the legs, -and thelocking feature of the legs relative tothe top providesl an.

easily operated i igid.table.which may be constructed ofjrelatively4 few and .simple parts.` y 1 I Changes may be made in the form,`coii7 struct-ion, and arrangement of the parts and the Vvarious steps inthe method may be varied Without departing from the ,spirit of the inreiition'or sacrificing any' ofits advanta-ges, and the rightrisliereby reserved to make allsuch changes as fairly `fall Within the vscope ofthe following claims. y l
