Fig. 10 ShOWSilihBtEibl' with the pedestals separated longitudinally as in Fig. 8 and also sepa- Cross tie members 34 connect the free ends of the slide members 1 and ID as well as 8 and i2 and provide stop means for limiting the transverse movement of the slides II and I3. Stop members 35 (Figs. 2 and 13) secured to the under sides of the slide members 1 and 8 and moving within slots 36 in the intermediate movable Fig. 12 is a perspective view of a crossed tie member adapted to connect transverse and longi tudinal slide members.

Fig. 13 is a cross sectional View of a number of transverse slide members showing the relation of slides 9 provide stop means for restricting the movement of the latter by abuttal relation with the .ends3'l of the slots 36. The arrangement of these stops and abbutal means is such that when the table is fully extended the stops will the slides and stop members adapted to limit the g movement of the slides.

The reference characters throughout the several views represent similar parts.

With particular reference to Figs. 1 and 2, i, 2, 3 and 4 represent the supporting pedestals, of which land 2 at least are equipped with drawers, 5. Near the top of each pedestal is a platform 6 above which is provided space for receiving the system of transverse slides of which the ones indicated at l are secured to the platforms of the front pedestals, while those indicated at 8 are attached to the platforms of the rear pedestals. Movable slides 9 interconnect the members 1 and B and provide means for relative transverse movement between the front and rear pedestals. Outwardly of the members I and in spaced relation thereto the members (9 are secured to the front pedestals and slides H are movably engaged between the members 1 and i9. inwardly of members 8 and in spaced relation thereto the members [2 are secured to the rear pedestals and slides l3 are adapted to move forwardly and rearwardly between members 8 andv l2. In right angled relation to the movable slides H and rigidly attached thereto are longitudinal slides M which are adapted to slide longitudinally between the slide guides i5 and I6 carried by the front section of the table top H. Similarly attached to the movable slides l3 are longitudinal slides l8 which are movably engaged between the iongitudinal guide members l9 and 29 secured to the rear section 2! of the table top.

In order to maintain a rigid right-angled relation between the transverse slides I1 and i3 and their associated longitudinal slides i4 and I8 respectively, I have provided metal braces having crossed transverse and longitudinal arms 22 and 23 respectively which are rigidly secured together at '25 (Fig. 12), preferably by welding.

Dovetailed inserts 26 are utilized as intercom necting. means between transverse slide member while rectangular inserts 21 carried by the longitudinal slides move within corresponding ways in the longitudinal slide guides.

Articulated with the rear section 2| of the main table top by suitable flush hinges 28 is a folding top section 29 which is adapted to be folded forwardly on top of the main top sections when the device is used as a desk (Figs. 4 and 5) or extended coplanar with the main table top sections when used as a table (Figs. 1, 2 and 3). Conventional means such as pegs 30 in association with holes 3| (Fig. 2) provide means of maintaining alignment of abutting edges of table top members, including extra table top leaves.

All of the pedestals are provided with wall members 32 which extend above the side panels and provide supports upon which the table top members rest. Also secured to the outer side panels of the rear pedestals are extensions 33 which form supports for the top members associated therewith.

prevent further movement of the intermediate slides 9 upon their associated members and so position the slides 9 that the upwardly projecting posts 38 attached thereto will be positioned midway between the inner edges of the main table top members whereby the posts will provide supports for the abutting edges of two auxiliary leaves 39 and 40 (Figs. 2 and 3).

A front or middle drawer 4| is supported by suitablev slide means upon the pendant guide members 4'2 attached to the front section of the table top. When the device is closed to form a desk (Fig. 5) the middle drawer moves rearwardly with the top to occupy a position between the pedestals and upon moving the front top section forwardly the middle drawer is positioned forwardly of the pedestals whereby the latter may be moved longitudinally inward (Fig. 6).

In order to limit the outward longitudinal movement of the pedestals I have provided stop members 43 across the ends of the longitudinal slide guides against which the slides l4 and I8 abut when the pedestals are fully extended longitudinally.

Pendant members 44 carried by the front section of the table and corresponding in vertical dimensions with the rear members 33 provide a means of closing the space above'the outer side panels of the front pedestals when the device is closed as a desk (Fig. 4).

If desired, the rear pedestals may be equipped with drawers 45 (Figs. 3 and 4) similar to the drawers 5 in the front pedestals. In this manner the piece may be used as a double desk and its utility extended.

Figs. 7 to 11 inclusively show diagrammatically various positions and stages of expansion adapted to be assumed by my invention in which the pedestals, crossed slides and middle drawer are indicated in dotted lines.

In operation, to convert the device froma closed condition as a desk to a table, the first step is to move the table top sections (still folded) forwardly with relation to the pedestals (Fig. 7). Thismaybe accomplished by pulling the pairs of pedestals rearwardly, one at a time; The pairs of pedestals may then be moved together longitudinally at this stage if desired and the hinged top section extended to form a square breakfast or card table with the pedestals grouped in the center of the table as in Fig. 9, from which position it may be extended transversely by separating the front and rear top sections (together with the front and rear pedestals) to accommodate either one or two extra leaves (Fig. 11). With the two pairs of pedestals moved together as in Figs. 9 and 11 the entire periphery of the table is provided with unobstructed space below the table top for the convenience of persons sitting at the table, whereby four people may comfortably be seated at the small table (Fig. 9) or a large number may be seated at the fully extended table (Fig. 11)."

In the event only two people are to use the table the conversion to a small square table is made directly after moving the pedestals rearwardly by simpl unfolding the hinged top section as in Fig. 8.

If a larger table than that shown in Fig. 9 is desired but to be occupied by only four persons, the square table of Fig. 9 may merely be extended transversely to accommodate a single extra leaf as in Fig. 10 whereby space is provided between the front and rear pedestals to accommodate persons sitting at the right and left of the table, thus making a conversion suitable for such a group without moving the pedestals longitudinally.

While I have shown a table with an extension suificient to accommodate two extra leaves, it is to be noted that provision for further extension may be made by introducing additional transverse slides similar to and associated with slides 9.
