Patented Mar. 10, 1931 UNITED STATES PATENT ori-ica JAIiRUS S. RICHARDSON, OF SHEBOYGAN FALLS, WISCONSIN, ASSIGNOR TO RICHARD- SON BROTHERS COMPANY, OF SHEBOYGAN FALLS, WISCONSIN, A CORPORATION OF WISCONSIN EXTENSION TABLE Application inea February 14, 1927. semi No. 165,036.

The invention relates to tables and more particularly to extension dining tables.

AItis customary 'in the manufacture of eX- tension tables to yemploy slides which are usually supplied as self-contained slide assemblies adapted to be suitably secured to the table top. Such slide assemblies consist of several 'slide meinbersgrouped together and` 2.0 separate slide assemblies.

Another object `is to provide a knock-.down yextension table which can be conveniently i and quickly assembled and .taken d oivn and which can be vpacked for shipment in a com- 25 paratively small and compact container.

The invention further `consists in the several features hereinafter set forth and more l particularly defined by the annexed claims. i ln'the vaccompanying drawings, Fig. 1 is 30 a longitudinal sectional elevation of an eX tension table embodying the invention l Fig. 2 is a bottom plan view of the table in extendedposition; i Fig.' 3 is a transverse sectional view taken 35 along the joint in the top, parts being broken away and parts being shown in section rand Fig, l is a. sectional,disassembled view of the tableparts as they appear in packed relation readyfor shipment.

In these drawings, thenunieral 10 desigf nates a set of table legs which have their upper en-d portions secured as usualin lateral abutment with the ends of side and end rails 11 and 12, respectively. The side and end railsl are 'j 45 secured together at their adjacent ends in a' Well known manner by corner brackets 13 receive the custoniar le attaching i l n Whlc y b 1 leg 10 is Iound desirable in .seme cases, this screws or studs 14 by means of which the legs may be conveniently dismounted when the" i 5 table is to be taken down. There are two separable aligned side rails 11 at each side of the table, and each end rail 12 with its two attached side rails forms a separable frame section complementary to the frame section formed by the other end rail and its tivo attached side rails. A table top section 15 forming a part of each frame section is secured to the upper edges of the railsI in each frame section, preferably by means of screws 1G, as seen in Fig. 3, projecting from the rails upwardly into the table top.

Each side rail 11 has a longitudinal groove 17 formed in its inner face, and the aligned grooves 17 in each pair of aligne-d side rails receive a longitudinal rib 18 projecting from one face of a slide member 19, the other face ofthe slide member being providedV with a similar longitudinal rib 20. In oider to rctainvthe slide members 19 relatively slidable in engagement with the groovcd side rails, 'f'

guide blocks 21 are secured to the under face of the table top sections near the meeting edges thereof and in spaced parallel relation to the adjacent side rails, and each guide block is provided with a longitudinal groove 22 re ceiving the rib 20 of the adjacent slide inember 19. The guide blocks 21 are secured to the table top by means of screws 23 projecting upwardly into the table top as seen in Fig. 3. Each .slide member 19 is preferably of elongated cruciforin cross section as seen in Fig. 3, although it may be of inverted T-shaped cross-section, and has its upper edge on the saine level as the under face of the table top sections in order to support filler leaves 24 when the table frames are drawn apart. In order to limit thescparating movement of thc table frames, a removable threaded pin or dlowel 25 is screwed into the end portion of each slide member 19 to project laterally therefrom in position to engage the end of the adjacent ,guide block 21, which may be provided With a notch 26 at its end to receive the pin .and thereby extend the range of movenient of the table sections without need for shortening the block. lf an additional center may befc'onv'eniently attached to a cross meintom edges of the slide members 19, as seen in Y Fig. 3.

In extending the tablefrom the contracted `'position of Fig. l, the table sectionsare urged lapart to the position oiI Fig. 2 during which movement the slide members have a relative slidingmovem-ent in the grooves 17 formed in the side rails l1 and in the grooves 22 oit the f guide blocks 2l.A .The tiller lea-ves 24farethen '.interposed.between the table top s-ectionsl slide members tobe Withdrawn and the table sections to :be entirely separated. The two table sections are then placed one next tothe other with the bottom edges of the front and Y' side rails l1 and 12 facing each other, the disf mounted legs and slide members beingplaced alone' the outer sides of the end rails and the filler leaves resting-on one of the table `top sections. vSuitable packing material may be interposed between the various parts to prevent marring of finished surfaces. The en- -tirev group of table partsin the above-noted vrelationcan be placed in an exceptionally y kmembers inthe-grooves ofv said side rails,

compact shipping container 28, as seen-in Y age f storage. n
