This? invention relates to""f`urniture1and.

has particular reference'to extension tables or tables having the "adaptability ofbeiiig.,

Another object of theinvention is to provldeimeans whereby a! vperson atene/end of the table' may lower the auxiliary leaf sok as toA permit -the separated end. parts ofy the normal top rto return to.` their contracted position while the auxiliary leaflie's lbew neathn With the foregoing and: other' objects View the invention consists the arrangement and combination of Vparts hereinafter described and claimed, and whilethe iii-v vention is not restricted totheeiractidetails of'construction disclosed or suggested herein,

Referring now more specifically to the drawings, but without intending to belimited to the design ofthe top or other portions thereof, Ishow my table as comprising a frame .havingA sidebars 10 and end bars 11, said frame being supported by any suitable means as corner legs 12. Additional cross pieces yare shown at 13, located subsection on i stantially mid-way between the end bars Extending transverselyof the frame along the transversel center line thereoflis anangle .member A14',In'eferably. of metal, the ends of.

Extending beneath they outer .edge ofy `each` i table top {portion 16, the edge' thatmay be defined as the end of. the table top, are one.` or kmore lugs "orvv blocks 20=seated normally `rin i .correspondingly formed notches in the end bar 11 "of the frame and.l extending between saidblocks 2() rand the adjacent cross bar 13` 'off the frameare contractile springs .221 tende'. ing to hold the top `portiontoy which ythe blocks 20-are attached in nestedor closed position asshown in Figs'l and 2. i Thetop members- 16, however, may beydrawn awa-y The auxiliaiy leaf 23 isnormally nested f, beneathftheiplane of the` table topvaiid is supported in recesses formed in vthe side rails 10. To effect the prompt rise orA liftingr` ofA fthisileaff23 when the sections 16 are v from eachother to the positionfshown in Fig. 2, against the force of the springs22.-

drawn .apart,1 providev alever 25 pivoted or hingedat 2G toone of thecross bars` 13and extending thence longitudinally ofthe table through the lower end of a plunger 27 guided for vertical reciprocations in the guide memi ber 15. The plunger 27 is formed with a hole 28 through which the lever 25 extends, ythe forward or free end of the lever having a handle29 which swings beneath the `remote end bar 1l of the frame. A contractile spring 30,`anchored in' the other of the cross bars 13, is engaged with the lever and tends by its contraction to lift the same, `the plunger 27, and the leaf 23. The strength of the spring 30 may be sufficient to hold the leafv 23` elevated reliably, but for positivey y holding of the same I may provide one ory more buttons or fastening devices 3l at either end of the leaf 23. As indicated best,

in Fig. 7, each of these buttons comprises 1ror a face plate 32 fixed to a plunger 33 extending into a socket 34 in the adjacent side rail 10, an expansion spring 35 serving normally by bearing against the head 36 at the inner end of the plunger, to hold the button either in its locking position as shown in full lines in Fig. 7 or in its idle position as shown in dot and dash lines. To the end of the plate 32 is fixed a lug 37 which enters the notch ory space 24; afterit is drawn outward by the operator from its idle position and swung through 180". The forni 'of' the buttons and especially the blocks 37 auxiliary leaf 23 will be vdrawn directly downward, being guided in such movement by means of the plunger along the guide 15. The handle end of the lever is then preferably locked by suitable means as, for instance, by a stay 38 i'iXed to the inner surface-of. one of the end bars l1, the stay having a notch 39 into which the lever l25 will be received and held. The plunger 27 is iiXed rigidly at its upper end in a socket member 40 attached rto or let into the lower surface of the leaf 23. The ends of the leaf 23fhave secured thereto vertical guide pins 4l slidable in bearings 42 formed in the `side rails lO whereby the leaf 23 will be held reliably from rotation around the vertical center.

1 claim:

l. In an extension table,a frame, means to support the frame, a normal table top comprising two parts supported upon the frame and slidable along the saine toward and from. each other for contraction and-extension'respectively of the table top,rmeaiis tending automatically to drawy the top ing it into the rplane of the table top when Vthe top members first mentioned are drawn.

apart.

2. A which the plunger is guided forl vertical ieciprocations in a vertical tubular guide fixed to 4and supported by the frame, said Y' guide having aslot within which the rlever` operates vertically.

3. In an extension table, the combination of a frame having sidebars,r a pair ofvnormal top members slidable along the frame Vdevice as set forth in claim 1 in` toward und from each other, an auxiliary` leaf, said sidebars being notched to receive and hold the auxiliary leaf in nested posiy tion when the table top is contracted,means to automatically elevate the leaf when the table top is extended, and means to positively hold the leaf elevated said last men-h tioned means being rotatable downward out of operative position when-said leaf is not;

used and consisting of buttons mounted on the side bars of the frame, each button'including a casing, a face plate therefor,

plunger, said lface plate being'l rotatably mounted on said plunger, spring means engaging the plunger to hold the' faceplate against the casing, and a block carried by the endof the plate adapted on rotation of said plate to lie in the recess-of the side bar and receive the weight of the leaf thereupon. f

In testimony whereof Ira'fiix'V niy-signature.
