T0 all 'whom t may concern.'

Be it known that I, CORNELIUS Ross, a citizen of I-Iolland, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Extension Tables, of which the following is a specification.

My invention relates more specifically to `a pivoted table leaf construction for extension tables. p

It is an important object of my invention to provide a foldable table leaf construction pivotally disposed on the frame of an extension table below the table top, and arranged to be elevated upwardly to fill the space between the table sections when they are drawn apart to form an extended top.

Another object is to provide a foldable table extension leaf construction that is extremely simple in construction, easily operated when it is desired to extend a table top, and which is not liable to become easily disorganized.

In the accompanying dra- Ying I have illustrated a preferred embodiment of my invention, it being understood, however, that no limitation is necessarily made to the precise structural details therein exhibited, but various changes, alterations and modifications may be resorted to within the scope of my invention when desired.

Fig. 1 is a plan view of an extension table in its closed position, the foldable extension leaf being shown in dotted lines.

Fig. 2 is a plan view of an extension table in an extended position, with the foldable extension leaf in place therein.

Fig. 3 is an enlarged transverse section of an extension table in a closed position equipped with my foldable extension leaf, taken on line 3--3 of Fig. 1.

Fig. 4 is a bottom plan view of an extension table with the table sections drawn apart, the foldable extension leaf in a folded position.

Fig. 5 is an enlarged longitudinal section of an extension table top, with the foldable extension leaf in position, taken on line 5 5 of Fig. 2.

Referring more specifically to the drawings, 6 indicates an extension table rectangular in form, consisting of two sections 7, S, each provided with a pair of supporting legs 9, 10, and a centrally disposed frame work 11, formed of longitudinally extending side bars 12, 13. Each pair of ends Iof the side bars are connected by a plurality of short bars 14, 15, 1.6, suitably secured to the side bars, and s} 3ac`ed. apart to form grooves 17, 13, the oppositely disposed faces of the various bars being provided with longitudinally extending tongues 19 that engage with grooves 20 formed in the' side faces of slide bars 21, 22, 23, 24, a pair of bars being secured to the `under face of Veach table section.

The above described construction is the form most generally employed'v in extension table construction, and therefore' form no?` part of my invention, except in combination with my foldabl'e extension` leafI whichv is attached thereto. Further, it will be perfectly obvious that the table top other than rectangular formation.

The foldable extension leaf is preferably formed in two sections 30, 31, rtheir abutting ends being hinged togetherby means of the usual well known concealed hinges may be of- 32. Each of the oppositelyj disposed faces of side bars v12', 13, .areprovided with longitudinally extending guide grooves 33, 34, the grooves extending between the oppositely disposed faces of said bars 16 as clearly shown in Fig. 4 of the drawings. Attached to the under ,face of section 31 of the foldable leaf and adjacent its hinged end by means of bearings 35, is a leaf elevating hinge 36, in this instance formed of stiff wire, the transversely disposed portion 37 of the hinge 36 is mounted in the bearings 35 and its side arms 38, 39, are bent at right angles thereto and lie parallel to the grooved faces of the side bars. treme ends of the side arms pivotally engage slide blocks 40 that are mounted in the grooves 33, 34, formed in the side bars, in order to permit of a forward movement of the leaf during its elevation. Securedto the under face offleaf section 31, at the proper distance from its outer end, is another leaf elevating hinge 43, similar to hinge 36, its transversely extending portion 44 being mounted in bearings 41, and its side arms 45, 46, lying parallel to the grooved faces of the side bars 12, 13, the extreme outer ends engaging bearings 47 secured to the outer side face of one of the end bars 16 substantially mid-way between its upper and lower edges. Side arms 45,

The exa ltween the table sections.

46, are bent at right angles adjacent their point of attachment to the end bar 16, in order that the side portions will lie parallel to the under surface of the leaf section when the leaf is swung into position be- The upper surface of bars 14, 15, 16, and bars 28, 24, on which the leaf section 81 rests when the leaf is swung into position, are cut away to form a depression 50 for the accommodation of the side portions 45, 46, of the hinge 43 when the leaf is in position between the table sections.

When the table is in its normal closed position, the sections of the extension leaf are folded upon each other, leaf 31 resting directly upon the upper edges of the side bars 12, 13, directly below the two sections of the table top, thus effectually concealing the. leaf from view, as clearly shown in Fig. 3 of the drawings. YVhen it is desired to extend the'top of the table the two sec tions are drawn apart (see Fig. 4), the operator then grasps the end of the leaf section toy which the elevating hinge 43 is secured and pulls the same toward him, the side arms of each of the hinges raising the leaf sections to a level with the upper surface ofthe tops of the table sections, the blocks sliding in the grooves 83, 34, of the side bars and permitting of a forward movement during the elevation, stops 51 disposed in the grooves 33, 34, of the side bars limiting the forward movement of the folded leaf sections. After the above opera tion has been completed the upper folded section 30 of the leaf is swung on its hinges into position to fill the space between the table section opposite to the space occupied by section 31. rIhe two table sections are then pushed together until their oppositely disposed edge contacts with the side edges of the leaf sections, thus completing the operation of extending the table top.

From the above description it will be apparent that I have provided a simple foldable extension leaf construction, that will be inexpensive to construct, and one not easily disarranged.

l/Vhat I claim is:

In combination with an extension table consisting of a pair of sections adjustably secured together, of an extension table leaf divided into two hinged sections and normally supported by the table frame below the tops of the table sections, a pair of arms pivotally attached at one of their ends to one of the leaf sections, their free ends being pivotally secured to the table frame, and a second pai-r of arms pivotally attached to the last named leaf section, their f ree ends being pivotally attached to movable pivot blocks, whereby when the table sections are drawn apart the foldable table leaf may be swung into an elevated position to fill the intervening space between the table sections.

In witness that I claim the foregoing I have hereunto subscribed my name this 7th day of June, 1924.

CORNELIUS ROSS.
