Fig. 12 is an enlarged view of the right end of Fig. 2. i In the drawings It indicates a main top of a pair of side rails which the table top extensionmay be elevated - table. A frame comprises H and two end rails 52. With the present form into the plane of the table top upon being ex of the invention, an individual leg-construction 25 25 tended from the nested or socketed position to the full extent of the extended movement and and mounting are illustrated, and herein the leg is indicated by the numeral 13, the anchor maintained in elevated relation. The present invention is illustrated herein as ing bolt by the numeral it, the adjacent rail connecting member by the numeral l5, and the of three di?erent types. locking nut by the numeral ‘it. This corner The full nature of the invention will be under stood from the accompanying drawings and the construction is standard in. table constructions. Any other corner construction, however, may be following description and claims: In the drawings, Fig. 1 is a bottom plan view substituted therefor without departing from the of the table, the legs being shown in section broader features of the invention. The top edges of the rails are spaced from the 35 and the table being equipped with the necessary elements to comprise a refectory construction. bottom plane of the top by a depth at least equal ’ to the thickness of the table top extension ll. Fig. 2 is a longitudinal sectional view taken These extensions are commercially known as on broken line 2—2 of Fig. l and in the direction slides. Obviously, the tops of the legs termi of the arrows. 40 Figs. 1 and 2 in the right hand ‘portion show nate in spaced relation to the top to permit 40 the top extension in the elevated and extended freedom of slide movement. The means for securing the frame to the top position forming a continuation-oi‘ the main top includes four L-shaped, in cross section, blocks of the table and the left hand portion of said 3, each of which has a portion iii that lies out ?gures illustrate a similar top, extension in the side of the side rail and a portion 213 that lies be 45 nested or socketed position. v tween the same and the table top and spaces the 3 isa bottom plan view of a modi?ed form rail from the top. Screwsv 2i secure the blocks 18 the provision of certain so-called “hardware” by of the invention, wherein a common control is associated with the individual “hardware” car-. ried by each of the slide bars of the extension top. ' ‘ 1i is an enlarged vertical sectional view of a modi?ed form of hardware similar to that shown in Figs. 1 and 2 and of the individually operable type, the extension being shown in the to the table top and any suitable means secures the rails to the blocks.‘ In this manner the frame, consisting of the legs and the end and side rails, 50 are secured in relatively spaced'relation to the table top and provide'an open space at each end of the table for nesting the slide or top extension l'i between the top and the frame and beneath the top; 55 2 2,111,616 To mask the anchoring blocks which are suit ably secured to the side rails and for ornamenta tion in forming an unbroken or non-gap surface between the two extension slides when nested, and for bridging the space therebetween, are the auxiliary rails 22 secured to the top as at 23. The opposite ends of these rails 22 as at 22a may serve asv stops for the rear edges of the exten sion slides when in nested relation. Any other suitable method of mounting the table top upon the frame work and providing open spaces at the ends of the frame immediately be neath the top for nesting the slides may be em ployed without departing from the broader fea 15 tures of this invention. Extending from one auxiliary side rail 22 to the other is an elongated member 24, the same be ing secured to the table top as at 25. Portions 26 of the member 24, in depth, are approximately 20 only the thickness of the top extension, or in other Words, the depth of the opening between the frame and the main top. The auxiliary rails 22 mask the ends of the member 24 at the extensions 26. rl‘he member 24 inwardly of the extensions 25 28 is of greater depth and includes spaced slots 27. ‘These slots 21 accommodate the slide bars. Herein a pair of slide bars 28 is provided for each top extension and is suitably secured thereto as at EU. The slide bars for each extension are offset relative to the bars for the other extension and‘ the width of the slot 2'! in the bar guiding mem ber 2A is double the width of the slides for two 35 extension All which is adapted to engage the bot tom edge of a notch 42 in an end rail l2, as shown clearly in the right hand portion of Fig. 2, to maintain the slide extension I‘! in position as an extension or continuation of the main top H). The spring 3'! permits the cam like head 43 of the member 39 to ride under a locking plate 44, suitably secured at 45 in countersunk relation upon the bottom of the table top. The counter sunk portion communicates with the elongated 10 slot 46 which is provided to permit tilting move ment of the member 39. A rod 41 is suitably se cured to the member 39 as at 48 and is slidably mounted in a groove 49 formed in the face of the slide bar bearing or the slide. The rod 41 carries at its free and outer end, a pull ring or similar device 50. The underface of each table top extension is provided with a ?nger grip or groove 5|. operation is as follows:- The 20 The slide is engaged by gripping the same at 5! and is pulled outwardly to remove the slide from its nested position, shown in Figs. 1 and 2 at the left, and as it is moved outwardly, the block 36 engaging in the slot 21, elevates the slide so 25 that the movement is more or less. in an inclined bar accommodation. The slots 21 in depth are considerably deeper than the depth of the bars. plane directed upwardly into the plane of the main table top. Near the immediate end of the extension movement, the depending portion 4| of the hardware, engages the bottom surface of the 30 slot 42 in the end rail l2. When thus engaged, the top extension is maintained in table top extension-forming position. When it is desired to nest the extension, the two pull rings 58 are Each bar near its free end carries an inclined member or block 38 which engages the bottom of supporting position, permitting the extension to the recess 27 and causes the slide in its extending movement to be automatically elevated until the full extending movement is obtained. Near the 40 end of the extending movement certain hardware, the speci?c subject matter of the invention, auto matically becomes operable to elevate the top extension into the same plane as the table top at the end of the extending movement and to 45 thereafter support the same in such plane until subsequently manually and positively released. Each bar intermediate its ends includes an in clined block 3! which has one edge 32 adapted to serve as a stop by engaging the inside of the end 50 rail l2 when the slide is extended. In alignment with each slide bar and near the free end thereof when the extension top is nested and secured to the table top, is an inclined block 33 which serves to force downwardly the rear or 55 free end of the slide bar and also serves more or less as a stop to prevent upward tilting of the ex tension top in the initial extending movement thereof. In other words, the end of the bar must ?rst clear the inclined member 33 before rela tively great tilting or elevating movement in the extending movement of the extension top is possible. This prevents marring of the top ex tension. In Figs. 1 and 2 of the drawings, one, and the 65 preferred individual form, of the automatically operable and manually releasible hardware for elevating without retraction of the extension top, illustrated. In said ?gures, the slide bar is recessed as at 313 and suitably secured therein, is a base plate 35. Said base plate has a tongue struck therefrom to lie within the con?nes of the recess 34. Said tongue serves as an anchor age for spring 31 secured .as at 38 to a depending arm 35? of a member which is pivoted as at 123 75 on said plate. The member 39 has a depending engaged which tilt the members 39 from their 35 drop downwardly and thereafter inward move ment of the extension will nest the same beneath the table top. In the form of the invention shown in Figs. 1 40 and 2, at the end of the extending movement, the upper portion 43 of member 39 having the notch 52 therein, through the influence of spring 37, serves to receive the edge of plate 154 to fur ther lock the extended leaf in the elevated position. The plate 35 has struck from it a stop 53 which limits tilting movement of member 39 under the in?uence of spring 31. In Fig. 4 a modi?ed form of the invention is 50 illustrated and in said ?gure, numerals of the one hundred seriesv are utilized. In this form of the invention, the additional sustaining means, such as the plate 43, cam portion 633 and notch 52 of the member 39, are omitted. In Fig. 3 a still further modi?ed form of the invention is illustrated and the same may be uti lized with either form of the invention shown in Figs. 1 and 2 or Fig. 4. In this form of the invention a single pull member is provided to 60 simultaneously actuate both of the automatic mechanisms embodying the hardware, the sub ject matter of the speci?c invention disclosed herein. In this form of bers 239 and 243 in turn connected ably supported as the invention, the two mem are connected by a rod 269, as at 25! to a red 24? slid at 2129 and terminating in a pull ring 25 . In this. arrangement, the plates 235 are posi 70 tioned in recesses upon adjacent faces of the slide bars and face each other while Figs. 1 and 2 illustrate a. reverse arrangement. In Figs. 5 and 6 is illustrated a simpli?ed ad justable form of the invention. Similar numer 75 3 2,111,616 als of the 300 series indicate similar parts. The table top» is indicated by the numeral 310, the extension top leaf by the numeral 3", the slide by the numeral 328, the notch therein by the numeral 334, the supporting plate by the numeral 335, the support member by the numeral 3“ piv oted to the plate 335 at 340 and connected to trip rod or means 347 at 343 and tensi-oned by spring 331 connected to plate 335 at 336 and to 10 member 3“ at 338. Rod 34'! is nested in chan nel 349. The end rail M2 is slotted at 342 to accommo date the slide bar 328. Rail SIZ supports in jux taposition to each slot 342 an angle plate 300 15 secured thereto by screws 30! in offset, parallel, inclined slots 302. Thus, angle plate 300 can be invention, reference being had to the appended claims. The invention claimed is:— 1.
