EXTENSION LEAF FOR TABLES.

Application filed March k1, 1926. Serial No. 91,336.

This invention relatesspecifically to an extension leaf construction Vfor tables having stationary tops, and is designed as an improvement on the construction illustrated and described in my `companionapplication entitled Extension leaf construction Yfor tables, bearing Serial Number 89,861, filed in the U. S. Patent Oflice February 23, 1926.

In the above mentioned application an eX- tension leaf constructionwas illustrated and described as applied to a table provided with metal guide bars, whereby the extension` leaves could be slidingly chainbered beneathv the table top orI withdrawn into an extended position.

TWhile the above construction operated in a satisfactory manner, yet thevnoise occasioned by the sliding of the metal hinge members or the metal guide rods was deemed objectionable.

It is therefore an object of this invention to provide an extension leaf construction in which the mechanism for slidingly operating the extension leaves will practically be iioiseless in operation and positive in action.

The above objects are accomplished by means of the mechanism described in the following specification, reference being had to the accompanying` drawings forming' a part thereof in which:

Fig. 1 is a perspective view of a table equipped with my extension leaves.

Fig. 1d is a perspective view of the top of the table with one of the leaves in an eX- tended position and the other in a partially extended position.

Fig. 2 is an enlarged cross sectional view of a table top showing one leaf in an eX- tended position, the companion leafA being swung downwardly preparatory to chambering the same beneath the table top, and in dotted lines in a chambered or secured position, the view being taken Von line 2,-2 of Fig. 4l.

Fig. 3 is an enlarged longitudinal section 1 taken on line 3-3 of Fig. 2.

- Fig. is a bottom plan view of the table top equipped with the extension leaves, one leaf being in a closed, and the companion leaf in an extended position.

Fig. 5 is a detail sectionalview showing one of the sliding supports for the leaves when extended. y

Briefly, the invention herewith presented preferably consists of employing a library table construction of a general well Lknown type including an elongated table top provided on its under face adjacent its edges with downwardly extending aprons. Se-

cured to the under-'face of the-top adjacent itsends and midway between its sides are a pair of legs terminating in bases connected together with the usual brace. The" outer edges of the extension leaves are of segmental form, and are liingedly connected to a plurality of slide members secured to the under face of the table top,'whereby the leaves when not in use may be quickly chanibered beneath the top. Provision-is made in the form of a double pivoted hinge in order that the leaves may be drawn outwardly and around the depending aprons of the table top without interference. t

In the drawings the extensiony leaf construction is illustrated in connection with a table of the library or davenport7 type consisting of an elongated top 10, having a pair of supporting legs 11, 12, secured adjacent its ends, each leg having a base 13, the legs being connected with the usual ornamental brace piece 13. Secured to the under face of the table top adjacent its end and side edge are depending aprons 14, 15, 16 and 17., designed primarily to conceal from view the extension leaves when chambered or secured below the table top, the aprons also serving to enhance the beauty of the tahle and lto impart massiveness thereto. j

As both extension leaves are exactly similar in construction and operate in the same manner and for the purpose of brevity of description only one will be described herein.

The outer edge of the extension leaf 16 is of segmental form, but any other form that may seem desirable may be employed without affecting its operation. Secured to the under surface of the table top are a plurality of cleats 18, arranged in triplicate adjacent the ends of the table to form a pair of grooved guide ways 19, 20, 21, 22, a pair for each leaf. Mounted in the guide ways are slide bars 23, 24.-, 25, 26, the tongues 27 ico on the bars-en gagiiig the grooves in the guide Ways. rl`he extension leaves are secured to the slide bars at their outer ends by means of double pivotedV hinges 28', each hinge con# sisting of an attaching member 29 rigidly secured to the outer 'face ot thefslide' bars and at their outer ends, while a similar member 30a is secured to the under surface ofthe extension leaf 31 at its table meeting edgea the Connecting member 32 ofthe hinge is ot angular torni and adaptedwhen the leaf is in an extended position (see Fig. 2) to extend under and around the depending apron lll ofthe table top. x u

In order to rigidly support theleaf 30 when man extended position a slide bar niountedin agroovedguide bar 3e is provided, the bar passing through an opening S formed in the apron 14ans best shown inl :ff Fig; 5,4 theV outer endot the slide bar having a dependin'g'poi'tion 3G designed to limit the inward inoveiner'it ot the bar when the leaie 30 isslid to itsv chaniberedposition beneath the' table top.

Frointhe above description itis thought that' the operation ot extending the leaves will beel'leaily apparent. The leaves 30 when not in use 'are chanibered beneath the table top, the inner ends ofthe leaves engaging oppositely disposed ledges' 36', 8'? secured to the"tablel'egsY l1, 12, directly below the loi'vei" en'd's 'of the apr'ons'for supporting' the leaves ina position parallelto the under tace ot the t'o'p, see' Figs. 2 and d. Vhen it is' desired to extend the chainbered leaves, each leaf 30 ispulled forwardly' towards the oper'- ator' until the outer ends of the slide bars therefor are needed7 and as ythe leaves are slidably mounted the opere-bionet extending the leaves is considerably siiiiplilied;
