PETER NYHOLM, OF EDGEVVOGD, UJ'ASHNGTON.

EXTENSION-TABLE.

Application led August 23, 1919.

To all whom t muy conc-em:

Be it known that I, PETER NYHOLM, a citizen of the United States, residing at Edgewood, in the county of Pierce and State of llashington, have invented certain new and useful Improvements in Extension-Tables, of which the following is a specification.

My invention relates to extension tables and has for its primary object to provide folding filler leaves for such tables which in y be stored beneath the permanent table top sections, whereby they are in convenient position for use when the table is extended.

The further object of my invention is to pro ide folding ller leaves with coperating attachments whereby they may be applied to any ordinary extension table.

My invention consists in the various novel parts and combination of parts as will be hereinafter more fully pointed out.

In the drawing Figure l is a top plan view of an extension table top with my iinproved iiller leaves in place and in extended position.

Fig. 2 is a similar view with some of the leaves in stored position and one leaf in emi extended position.

Fig. 3 is a vertical sectional view looking in the direction of the arrow on the line 3--3 Fig. 2.

Fig. 4 is a detailed sectional view, looking in the direction of the arrow on the line L -4C Fig. 2.

F ig. 5 is an enlarged detailed view of a filler leaf, in extended position, and broken away.

Fig. G is an end elevation of a filler leaf in closed position and broken away.

Figs. 7 and S are detailed vertical views of a center pedestal table showing my invention applied.

The reference numerals l and 2 designate the permanent table top sections of an extension table of any approved constru wtion, said table being provided with the usual extension slides 3 and 4, the slides et being secured to the permanent sections l and 2 as shown in Fig. 2.

Beneath the slides I position a suitable support which, in effect, constitutes the base upon which the ller leaves are mounted, said support may be secured to the center leg- 6 of the table in any suitable manner.

@n the support 5 I nal bearing blocks G position suitable jourm series, the number Specification of Letters atent.

being' dependent upon the number of liller leaves employed in said blocks and journal rod 7 which rod may be common to all of the filler leaves. To one side of the journal or rod 7 I secure center guides 8 to the journal bearing blocks C, said guides being inclined toward the center of the space between said blocks as clearlv shown in Fig. 7. u

A link 9 is loosely journaled, at its lower end, on the rod 7 between a pair of the your-nal blocks 6 whereby the link is free to swing to both sides of the rod 7. as in the position shown in Fig. 3 and to the position shown in i to facilitate the storing and the extension of the folding iiller leaves l0. The sections of the folding iller leaves are connected together by means of a suitable hinge which ninoe, in the illustration shown, comprises two members ll the abutting ends of each of which are provided with a recess l2 in which a link i3 is mounted, said link being suitably secured to the respective hinge members by means of the pivots 11i, whereby the sections of the iiller leaves may moved into and out of folded and extended position without binding at the abutting edges of the sections of the leaf. One of the sections of the leaf is provided with a projecting support l5 abridging the joint between the two sections of the leaf, thereby relieving the hinge of any undue strain or tension as will be understood by those skilled in this art. Each folding iiller leaf is provided with journal bearing blocks 16, arranged in pairs between which extend a rod 17 which passes through said blocks und also passes loosely through the upper end of the link 9 whereby the link 9 has a loose pivotal connection with the filler leaf.

in order to limit the downward movement of the link 9 on one side of the rod 7l provide a stop 17 having an inclined upper face the angle of which is predetermined so that the link 9 engages the stop 7 when the iiller leaf has reach/ec the position of the top plane of the permanent table top as shown in Fig. 4f. yl`his stop not only limits the do'vvnward movement of the link 9, as aboY-.fe described, but it also serves as a support between s journal rod 7 and its connection 17 with me filler leaf to support inner end of the ieaf section in its elevated position as shown in Fig. l. ln order to further support the iller leaf formed on an angle which insures a snug Contact tit with the upper surface of the link 9 as clearly shown in Fig. Ll. A strip 19 is secured on the support 5 upon which rests the free ends of the folding leaf as illustrated in Fig. 3.

. `When my attachment is used in connection .with a split center pedestal the support 5 is secured to the center leg Q0 whereby the sections 21 of the split pedestal are free to move with the permanent sections of the table top.

From the above it will be seen that to place the filler in operative extended position it is only necessary to grasp the leaf desired and with the upward movement swing the leaf on its link 9 thereby moving the folding leaf to proper position to be extended whereupon the uppermost section of the leaf ismoved over on its hinge connection so that the leaf is presented in its extended position level with the upper face of the permanent table top sections. There is no additional movement or adjustment of any parts necessary to secure the filler leaf in itsfproper extended position and the stops and links rigidly hold the filler leaf against endwise movement as well as against collapsing downwardly at its hinged joint, so that the liller leaves are just as rigid in their extended position as are the permanent table top sections.

If desired the filler leaves may be proi vided with the usual pegs and peg sockets and when so provided the link is made relatively narrow whereby 1t has a ater freedom of sidewise nifweinent betr 'een its journalblocks 6 to accommodate the movement necessary in inserting the pegs into the pegV openings of adjacent leaves.

That I` claim is 1. In an extension table the combination with the table tcp structure having a compartment for storing extra table leaves, of a link pivotally mounted at its lower endy the downward movement of said link on oneV side of its pivotal connection, a folding table leaf'pivctally mounted on the upper end of said link, and means on the under face of said'table'leaf adapted to engage the link said means cooperating with the first mentioned means to limit the downward movement of said link on one side of its pivotal connection. Y j

3. Inan extension table, thecombination with the table top structure having a compartment for the storage of eXtra table leaves, of bearings within said compartment, a rod mounted in said bearings, a link pivotally mounted at its lower end on said rod and free to swing to either side of said rod, a folding table leaf pivotally mountet on the upper end of'said link, a stop in said compartment, and aV stop on the under face of said table leaf, both stops engaging said linkto limit the downward. movement of the link on one side of its pivotal connection.

l1. In an extension table, the'combination with the table top structure, journal bearings secured to said structure anda journal extending between said bearings, a link pivotally mounted at .its lower end on said ournal,` a folding table leaf pivotally mounted on theV upper end of said link, said link being capable of moving to bothsides of its lower pivotal connection, stops mounted on the table structure andV on the folding table lea adapted toengage the link and cooperating to limit the downward movement of the link on one side of its journal, whereby the leaf may be swungin folded condition below the level of the top of the table and whereby it may be moved` on4 said link to the plane of the top of the table, said link being adapted' to slide sidewise on its journal, and guides to one side of saidjournal adaptedto center the link between its journal bearings when the table top is in stored position.

5. In` an extensionV table the combination with the table top structure having a compartment for storing extra table leaves, of a link pivotally mounted at its lower end within said compartment and adapted to swingtobothsides of its pivotal connection, folding table leaf one section of which is pivotally connected to the upper end of said link, and a stop secured. to saidl folding leaf between the joint of` said leaf and the point of connection of the link to said leaf and adapted to engage said link to hold the leaf in the plane of the top of thetable.

In testimony whereof I aHiX my signature.
