The object of my invention is to pro-' vide for an extension table a two-part extension leaf whichmay be hidden Within the body of the table beneath the main leaves and so mounted that it may be automatically projected into or from storage position by the simple application of a lifting force to the outer end of one section of the leaf. The accompanying drawings illustrate my invention. I i

Fig. l is a plan of the middle portion of an extension table equipped with my improved leaf,only the inner edges of the main leaves of the table being shown and separated to show the extension leaf mounting;

. Fig. 2 is a transverse section on line 22 of Fig. 1, withthe extension leaf in storage position; V

3 is a section on line 2-2 of Fig. 1 with the extension leaf in an intermediate Fig. 4 is a section on line 44 of Fig. 1 with the" extension leaf in service position; Fig. 5 is a fragmentary section online 5- 5 of Fig; 4, the extension leaf being shown in service position, and

Fig. 6 is a fragmentary section on line 1 66 of Fig. 4, the extensionleaf being shown in servicepositionL V In the drawings 10 and 11 indicate usual main separable leaves of an extension table correlated by the usual slide bars 12, 12, said leaves carrying the usual depending aprons 13.

. Mounted upon the usual supportof the slide bar structure on opposite sides of the median line of the table are two U-shaped brackets 16 and 17. Pivoted to the vertical arms of bracket 16' are the ends of a U- shaped leaf-lifting bar 18 and pivoted to the vertical arms of bracket 17 are the ends of a U-shaped leaf-carrying bar 19, the tie 18 and 19 being oppositely placed relative.

table when the extension leaf is in service,

position. Hinged to the inner end of extension leaf section 21, preferably by a concealed hinge such as hinge 22 is the inner end of the second extension leaf section 23. The upper ends of the vertical arms of bracket 16 are formed at 16 into seats for the U-bar 19 and are so positioned that when said U-bar is seated in the seat 16 and leaf .21 isextended to service position said leaf section will be supported in the table leaf plane resting upon the cross bar of U-bar 19 and upon one of the slide bars 12.

Oneedge of the extension leaf 21-23 is provided with the usual dowels 24 for entry into the usual pockets 25 in the inner edge of main leaf 10 and the other edge of the extension leaf section 21-23 is provided with pockets 26 adapted to receive the dowels 27 carried by the inner edge of leaf The side arms of the two lJ- bars 18 and 19 are connected by the links, 30, 30 which U-bar 19, through the links 30, swinging upwardly. The free end of extension leaf section 23 rests upon the cross arm of U-bar l8 and as leaf section 21 is lifted and U-bar 19 swings upwardly said U-bar serves to lift 1 ll-bar 18 and thus raise the free end of extension leaf section 23, as said leaf 23 is propelled toward the adjacent slide bar 12 so that said free end will clear the adjacent slide bar 12. The hinged end of extension leaf section 21swings toward the median plane of the table, the hinged edge ofextension leaf section 23 sliding upon bar 15 until the cross arm of U-bar 18 rests upon bar 15 and the cross arm of LE-bar 19 rests upon the upper endsof the vertical arms of bracket 1.6, whereupon further downward movement of the free end of extension leaf section 21 will bring said leaf section down upon the ad] acent slidebar 12 and extension i.

leaf section 23 will rest upon the opposite slide bar 12.

Thereupon main leaves 10 and 11 may be projected toward each other and into en gagement with the extension leaf, the dowels and pockets mating so as to vertically interlock the two extension leaf sections with the main leaves of the table.

In order to store the extension leaf th main leaves 10 and 11 will be separated, the free end of the extension leaf section 21 swung first upwardly and then downwardly, pivoting on the cross arm of the U-bar 19, and the free end of extension leaf section 23 being lifted by iJ-bar 18 and then lowered as its free end clears the adjacent slide bar 12. v

I claim as my invention: 7

1. An extension leaf structure for extension tables comprising a pair of extension leaf sections hinged together at their adjacent ends, a lever pivotally associated with the under side of one of said leaf sections and pivotally supported on a table base, a second lever pivoted to said table base and cooperable with the other leaf section to lift the same, and, a connection between said two levers.

2. An extension leaf structure for extension tables comprising a pair of extension leaf sections hinged together at their inner ends, a bracket, a U-bar having its cross element pivoted to the under side of one of said leaf sections and its free ends pivoted to said bracket, a second U-bar pivotally mounted at its free ends and having its cross element disposed beneath the other extension leaf section to form asliding support therefor, and connecting links pivoted to the two U-bars intermediate the ends of said bars.

3pMounting hardware for an extension leaf forextension tables comprising a supporting bracket, a U-bar pivoted on said supporting bracket and adapted to have its cross bar pivotally associated with an ex tention leaf, a second bracket, a U-bar pivotally associated with said second bracket and oppositely arranged relative to the first U-bar, the cross bar of said second U-bar being adapted to have a sliding engagement with the under face of an extension leaf section, and a connection between the side arms of said U-bars. 7

4. Mounting hardware for an extension leaf for extension tables comprising a supporting bracket, a lever pivoted at its one end to said bracket and provided adjacent its opposite end with means adapted to connect said lever end pivotally to an extension leaf section, a second bracket spaced from said first bracket in the direction of extenits one. end. to said. second bracket andpro jecting oppositely relative to said first bar, the free end of said second lever being adapted for sliding engagement with a second extension leaf section, and a link pivoted to said levers intermediate the ends thereof.

5. An extension leaf structure for extension tables comprising a lever pivoted at its one end to a table. base, an extension leaf section, meanspivotally connecting'the free end of said lever to said section intermediate the ends thereof, a second extension leaf section having its one end hinged to an end of said first leaf, a second lever pivoted at its one end to said table base and having its opposite end underlying the free end of said second section, and a link'pivoted to said levers intermediate the ends thereof. I

6. in combination, a table comprising a base, spaced parallel slide bars mounted on opposite sides of the longitudinal median ine of said table, a pair" of main leaves mounted on said slide barsand relatively movable longitudinally of said base,- said slide bars forming; with said base, ade pressed pocket of a transverse dimension less than that of said leaves, and an extension leaf unit permanently mounted in said pocket and comprising two extension leaf sections hingedly connected to each other, a lever pivoted to one of said sections and to said-base whereby said sectionis swingable about an axis parallel to said median line, and a second lever pivoted to saidbase and engaging the other of said sections whereby, when said first section is swung about its axis and into the" plane of said main leaves, said second section'is also projected into the plane ofsaid main leaves.

In witness whereof, I have hereunto set my hand at Wabash, Indiana, this 15th day of March, A. D. one thousand nine hundred and thirty. v
