To @ZZ whom t may concern.'

Be it known that I, DOCTOR FRANKLIN OLIVER, a citizen of the United States, and a resident of Oakland, in the county of Alameda and State of California, have invented a new and Improved Extension-Table, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved extension table having slidable end leaves, and extension leaves at the middle of the table and adapted when not in use to be folded within the table rim, the arrangement permitting of readily moving the extension leaves into extended position flush with the end leaves.

For the purpose mentioned, use is made of extension leaves adapted to move transversely into extended or folded positions and provided with pivots engaging fixedtransverse guideways extending in opposite directions to permit of swinging the extension leaves on their pivots and pushing the same into positions one above the other and both below the table top.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l -is a plan View of the extension table with the extension leaves in active position; Fig. 2 is a like view of the same showing the end leaves moved outward prior to moving the extension leaves into folded position; Fig. 3 is a plan view of the extension table with the extension leaves in folded position; Fig. 4 is a sectional side elevation of the extension table on the line 4 4 of Fig. l; Fig. 5 is a cross section of the same on the line 5-5 of Fig. 1; and Fig. 6 is an enlarged plan view of one of the pivots.

The frame A of the extension table is mounted on a suitable leg or legs B, and on the said frame A are fixed longitudinallyextending slide yguideways C engaged by slides D. D and D Dsecured to the under side of the end leaves E and E to permit of moving the end leaves E, E outward into an extended position, as shown in Figs. l, 2 and 4, or inward into a closed position, as shown in Fig. 3. rIhe detail construction of the guideways C and the slides D, D is` similar to the ones used in extension tables as now constructed, so that further description of the same is not deemed necessary,v

Extension leaves F, F are adapted to fit between the end leaves E and E whenever 1t is desired to extend the table, or the said extension leaves F, F are moved tra-nsversely into folded position immediately above the frame A and below the end leaves E, E when the latter are in the closed position shown in Fig. 3. For the purpose mentioned the extension leaves F, F are provided on the under surface at the sides with longitudinally-extending pivots G, Cr engaging pairs of transverse guideways H, I-I, preferably in the form of grooves formed in the opposite inner faces of transversely-extending rails I attached to the top of the frame A of the table. The guideways I-I and H are inclined in opposite directions, as plainly indicated in Fig. 5, and the lower ends of the guideways H are on a lower level than the lower ends of the guideways H, which latter are provided at their upper ends with horizontal extensions H2, as plainly shown in Fig. 5. By reference to Figs. 2 and 4, it will be noticed that the guideways H and H are arranged in different vertical planes, that is, the guideways H are somewhat deeper than the guideways H and the upper ends of the latter terminate in the guideways H at 0r near the junction of the horizontal portions H2 with the inclined part of the guideways H. Now by the arrangement described. the extension leaves F and F can be tilted on their pivots Cr, Cr and pushed transversely so as to cause the pivots G and Cr to travel in the guideways H and H. By having the horizontal extensions H2 on the guideways H, the extension leaf F can be drawn outwardlv in a transverse direction so as to unlock the adjacent inner tongue and groove edges of the extension leaves F and F see dotted lines in Fig. 5l, to allow of bringing the extension leaf F into the position shown in dotted lines prior to pushing the extension leaf F downward into a lowermost or a folded position immediately on top of the frame A. After the extension leaf F is moved into a folded position as described, the extension leaf is pushed inward so that its pivots G travel along the horizontal portions H? of the guideways H to lfinally travel down the latter to allow of folding the extension leaf F on top of the extension leaf F. and below the level of the end leaves E and E. Thus after the extension leaves F and F have been folded the endleaves E and E are pushed toward each other into a closed position, as shown in Fig. 3, to cover` up the extension leavesFand F. Vhen it is desired to extend the table, the end leaves E and E are pulled apart, and then the ex-.

tension leaf F is drawn upward and outward to; thev position shown in dotted,V linesin Fig. 5, to permit .of drawing out the other extension leaf F until the extension V'-leaf- Ff is in raised position, and then the extension leaf-Ffis pushed Atoward the extension leafl F tolinterlock the opposite edges by their interlocking,tongueand groove. In practice, the end leaves E and E are pushed out fartherthan the width of the extension leaves F, F" (see Fig. 2), soasto permit of conveniently manipulating lthe extension leaves FandF4 when foldingvthe same or extending the same as above described. After the leaveslFIand -Fiare in'extended position, the end leavesFvand E Vare pushed toward each other until theirv inner. edgesy abut against the sidev edges of the extension leaves Fand Ff, as Yshown in Figs.` 1 andt.

Each ofy thex pivots G ,and G,is preferably formed of asingle piece of-gmetal' having an attaching iatiportion Gzfastenedby screws or other means to the under side of the corresponding extension leaf F or F",-

and the flatl portion G2 terminates in a til-- bular shank G? provided at its end with a headGt, the shank G3 and the head GA1 fit,-A ting the Correspondingly-shaped groove formed inthe guideway' H or H. Each pivot YG'is also provided v'with a keeperV G5 in the form ofan opening formed at the bent portion G6 connecting the flat portion Giwith'the tubular ,portion G3, and 'the said keeper G5 is adapted to beengaged -byr a pin J secured to the under sideof thecor-VA responding leaf EY or E., By reference to Fig.r`2 -it will be `seen that the pins J project beyond the; inner Aedges ofthe end `leaves andare in alinement with the correspond-v ing pivots G, `2G so that when the end leavesAV ELF/*are moved into closed position attireV time the extension leaves Fand Fg are in raised and extended position, then Vthe said pins J tenter the keepersl G5` thus interlocking the end leaves E land E with th e' ex` l tension leaves F, and F, to 'securely'I holdA the end leaves and fthe extension "leaves firmly inv extendedand flush positiononeV relative to the other, as willbe readilyunderst'ood by reference tojFigs.` 1 and 4. Y

The extension table shownand Ldescribed is very simple, and, durablev in construction and composed of comparatively' few parts,

notliable easily Yto get out of order.
