This invention relates broadly to furniture, and has more particular reference to a table.

In accordance with the present invention an improved extension table, such as a refectory table or the like is provided, the top of the table having extension sections which when not in use are located beneath the fixed or main top section, and which when in use are secured in the same plane with the main top section through the medium of interengaging means carried by the main top section and the extension top section.

The invention together with its numerous ob- Jects and advantages will be best understood from a study of the following description, taken in connection with the accompanying drawings wherein:

Figure 1 is a bottom plan view of one embodiment of the invention, the extension top sections being arranged in their outermost positions and in the same plane with the main top section.

Figure 2 is a longitudinal sectional view with the top in fully extended position.

Figure 3 is a view similar to Figure 2 with the extension top sections being shown nestingly arranged relative to and beneath the main top section.

Figure 4 is a transverse sectional view taken substantially on the line 44 of Figure 3.

Figure 5 is a fragmentary bottom plan sectional view taken substantially on the line 55 of Figure 6.

Figure 6 is a fragmentary sectional elevational view showing the inter-engaging means on the main top section and the extension top section for sustaining the latter section in the same plane with the main top section.

Figure 7 is a sectional view taken substantially on the line 1-1 of Figure 6.

Referring more in detail to the drawings it will be seen, that in the present or preferred form of the invention, the main top section Ill which may be of any conventional construction is shown as rectangular and is fixedly secured to an under supporting frame having sides II and ends I2. At each end of the table there is an open space between the under side of the top Ill and the upper edges of the sides II and I2; and at each end of the table there is an extension top section I3, whose length is substantially equal to the width of the top section III, and each section I3 is, when not in use adapted to be arranged within the referred to space as shown in Figure 3.

To the under side of each top section I3 there are secured two bars It, said bars It being relatively spaced, and passing through slots I 5 in the ends I2, and at their inner ends being connected by a cross bar I6.

Adjacent each end member I2 of the frame, and in parallelism thereto, there is suitably 5 mounted between the sides II a reinforcing bar H, the same being preferably of metal and having a flanged upper edge suitably secured to the under side of the table top section III at Ill and sides II at III. Bars III] are suitably secured to 10 member I1 and to the table III at II to. Each bar I! is provided with rimmed or flanged slots or openings I8 alining with the slots I5 in an adjacent frame I2; and through these slots I 8 are slidable the inner ends of a pair of bars I4. Blocks 15 I9 are secured to the under sides of the bars I4 adjacent the inner ends of said bars and said blocks I9 have beveled ends Isa, to facilitate passage of the blocks I9 through the slots I8 when the top sectionv I3 together with its bars I4 is moved outwardly beyond the end of the table. It is also apparent, that upon such outward movement of the sections I 3, the blocks I9 passing into the slots I 8 serve to elevate the sections I3.

The sections I3 are yieldably retained in their retracted positions, that is in position beneath the table top section III through the medium of coil springs 20, each coil spring being anchored at one end I200 to a bar I1 and at a relatively opposite end I2llb to the cross bar I6 connecting that pair of bars I4 passing through the slots I8 of the other of said cross bar I1 as will be clear from a study of Figure 2.

Each bar I4 intermediate its ends has secured fixedly thereto at one side thereof a countersunk catch member 2|, which catch member 2| is in the nature of a hook the shank of which is of fiat plate like construction and is provided adjacent its upper end with a bill or extension adapted to be received in a groove 22 on the under side of the top section III and to move longitudinally of the groove in one direction to engage a keeper plate 23 countersunk as at I23 and secured at its ends by screws or other suitable fastening elements 24 to the under side of the top section I0 adjacent one end of the groove 22. With the hooks 2| so engaged with their respective plates 23 it will be seen that the tabletop section I3 will be supported from the main top section III in the same plane with said main top section, and in edge abutting relation therewith by means of the spring 20 or its equivalent.

In actual practice, when the extensions I3 are not in use they are, as before stated, arranged beneath the table top section I II, being located in the spaces between the end portions of the table top section III and the upper edges of the sides II and I2. When it is desired to enlarge the table top at either or both ends, either or both of the sections l3 may be moved outwardly, respectively. In this connection it will be noted, that when initially moved outwardly the section l3 will move straight outwardly until the inclined faces l9a of blocks I! come into contact with the rims at the lower portions of slots I8, whereupon the bars I4 will be elevated as the blocks l9 pass through the slots. When the section l3 has been moved outwardly beyond the end of the top section In in its elevated position, the section I3 is then moved backward until its inner edge engages the end edge of the section Ii). Upon backward movement of the section 13, the hooks 21 whose upper ends, upon elevation of the bars [4 in the manner just explained, were projected into the grooves 22 will move into engagement with the plates 23 so that with the, hooks 2| so engaged with the plates 23 as shown infFigure '6, the'end section l3 will be secured in its extended position and in the same plane with the main top section III, By reason of, the spring 20 associated therewith, the section l3 will be yieldably held in edge abutting relation with the main top section Ill and thus possibility of the hooks 2| being disengaged from the plates 23 is reduced to a minimum.

To retract an extension I3, the same is drawn outwardly away from the section III and then under action of the spring 20 will be urged downwardly and drawn rearwardly into its nested position beneath the top section It. Members 0 and I1 constitute an inner "frame, while sidesfll and ends l2' constitute an outer frame.

Even though I have herein shown and described the preferred embodiment of the in'ventionfit is to be understood that I do not wish to limit myself i to the precise details of construction, combine tion and arrangement of elements. herein shown, but claim all such forms of the invention topwhich I am entitled in view of'the requirements'ofthe art and the scope of, theap-pended, claims. 1
