3 Claims.

The invention relates to an improvement in extension tables.

Among the objectsis:

To provide a table which, when unextended, will show no evidence of its extensibility.

To provide a table which, when unextended, will present an unbroken top with drop leaves.

To provide a table capable of extension to the right or left from a main top, or to both the right and left, and

To provide a table in which the main top, from which the extension is made, will maintain its normal leg support when the table is extended and the extension will have its own leg support.

The invention can best be seen and understood in the light of the drawings in which Fig. l is a perspective of the table when unextended.

Fig. 2 is a perspective of the table when extended.

Fig. 3 is a top plan of the table extended with one of the top leaves removed and one of the drop leaves turned down.

Fig. 4 is a cross section on the line 4 4 of Fig. 3.

Fig. 5 is a perspective of a portion of the table when extended showing especially its extensible parts.

Fig. 6 is a cross section on the line 6 6 of Fig. 3.

Fig. 7 is a side elevation of a detail of construction, and

Fig. 8 is a side elevation of a fragmentary part of the table when unextended.

In the table in its unextended form I represents its top; 2 2 side aprons; 3 3 end aprons; 4 4 drop leaves, and 5 5 5 5 supporting legs. Beneath the top spaced therefrom are table braces 6 connecting with the aprons 2 2. Interposed between the braces Ii are brace blocks I all xedly combined.

The top, side aprons, and legs are xedly combined in any suitable manner and remain unchanged irrespective of any extension made to the table. The end aprons 3 3 and drop leaves 4 4 are supported as will presently be explained from parts by which the table is extended, and these parts, when the table is unextended, lie concealed nested within a chamber, or housing, beneath the top which is formed by the top, side and end aprons.

The parts by which thetable is extended comprise four sets of rail extensions 8, Il, I!) and II each comprising rails I2, I3, I4. Of these the rails I2 are xed and the rails I3, I4 extensible in the usual manner. The sets of rail extensions 8 and 9 are arranged for extension to the right, and sets Ill and II to the left.

The rails I4 for all the sets of rail extensions occupy the foremost positions when the rails 5 are extended. Fixedly secured to the outer ends of these rails for the sets 8, 9; I0, I I, respectively are the end aprons 3 3 of the table. Each end apron is faced with drop leaf supporting blocks I6, I'I and I8 xedly secured to the apron in any l0 suitable manner. Secured by hinged connections I9 to the top faces of these blocks for the respective aprons are the drop leaves 4 4 of the table.

When raised each of the drop leaves is supported to lie flush with the table top by hinged brackets 2, of which there are preferably two brackets for each drop leaf. The brackets have hinge connection (of conventional type, not shown) with the blocks I6, I'I, to which the respective leaves lie adjacent, the parts forming the hinge connection between the brackets and blocks being connected by pintles 2|. When folded, to permit the leaf to be dropped, the brackets fold in to lie, respectively, between the blocks I6 and I'I and the intermediate block I8, the brackets 25 and blocks then lying flush with one another.

When the table is extended each extension has its own leg support consisting of legs 24, 241. These legs are secured by hinge connections to the respective rails I4, I4 of the extension to 30 occupy either operative, or out of the way positions, the leg 24 being secured to one rail, and the leg 241 to the companion rail. When moved to occupy operative positions they turn outwardly beneath the rails to project in vertical directions downwardly therefrom with the top face 26 of each leg bearing against the bottom face of the rail from which it extends. At the same time a ange forming extension 21 at the top end of the leg will be brought to bear against the side of the rail (see Fig. 6). This assists in localizing and giving firmness to the leg when extended. When moved to occupy their out of the Way position the legs fold inwardly beneath the rails I4, I4 in crosswise relation thereto to lie boxed between the end apron 3 of the extension and a brace bar 28 crossing the rails I4, I4 on the under sides thereof and xedly secured thereto. When thus folded the legs lie parallel to one another with extension in reverse directions from the points at which they are hinged. l

The legs 24, 241 are held extended and braced each by a foldable brace 30. For the leg 24 one end of its brace is pivoted to the leg and the other end to the apron 3 of the table, the brace 55 folding with the leg to lie Within a housing 3lv withinl the apron. The brace for the leg 241 is pivoted at one end to the leg and the other end to the bar 28 Within which is formed a housing 3I1 for thebrace when folded with the leg.

When folded to lie boxed between the, apron 3 and the bar 28 the legs 24, 241 are each held by a dished tip 32 on the end of the leg engaging a catch 33 carried by a block 34 xed to the under side of the rail to which the end of the folded leg lies adjacent. The folded legs may also be supported, if desired, by a button 32l pivoted to the bottom side of the bar 28.Y

When the table is unextended the rail extensions 8, 9; I0 and II, the aprons 3 3, the legs 24, 241 and parts incidental thereto all lie concealed beneath the top I of the table which together with the aprons V2--2 and 3-3 provide a housing therefor. The drop leaves 4-4 will then overhang the aprons 3--3 and whenraised will coordinate with the edges of the table top to lie flush with the top. In this connection it will be seen by reference to Fig. 8 that with the table unextended the aprons 3 and blocks I6, I1 and I8 with which the aprons are faced will have entered to lie between the permanent legs of the table, and the drop leaves 4 will occupy positions adjacent the formed edges of the table sothat when the drop leaves are raised they will properly coordinate4 with these edges. This effect is obtained by the rail extensions 8, 9, I and I I having a limited inward movement as is customary in such extensions.

When the table is extended extension leaves 35 are laid over the extended rails and when raised the drop leaves coordinate with the edges of these inserted leaves to lie flush with the inserted leaves and table top.

To prevent lateral displacement the inserted leaves 35 are preferably provided on their under sides with aprons 36 at either end thereof which overlap the ends of the aprons 3 with bearing against'these ends.

We claim:

l.
