EXTENSION-TABLE.

SPECIFICATION forming part Of Letters Patent No. 623,682, dated April 25, 1899.

Application led March 2, 1898.

To all whom t may concern.-

Be it known that I, CHARLES W. MUNZ, a citizen of the United States, residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Extension-Tables, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to that class of eX- tensiOn-tables in which the leaves when not in use are stored in the body portion of the table and are drawn out with the slides when the table is extended.

It is the objectof my invention to obtain a construction in which increased extension is obtained by storinga double tier of leaves without rendering the table heavy or clumsy in appearance; and to this end my invention consists in the peculiar construction, arrangement, and combination of parts, as more fully hereinafter described and claimed.

In the drawings, Figure l is a vertical longitudinal section through one-half of my extension-table, showing it partially extended. Fig. 2 is a cross section thereof with the leaves in their stored position. Fig. 3 is a section similar to Fig. l with the table fully extended, showing in full and dotted-lines the different positions of the leaves when engaging and disengaging them from each other. Fig. 4 is a bottom plan View of my table with the leaves of one end extended and of the other end stored. Fig. 5 is a section on line x Fig. 2. Fig. 6 is a section on line y y, Fig. 5. Figs. 7 and 8 are end and side elevations, respectively, of the swinging post for supporting the leaf. Fig. 9 is a sectional perspective view showing the connection between the side rails and cross-tiers of the table.

A is the center or body portion of the table, which comprises the top a, the side rails b, having the longitudinal grooves c on their inner faces, and the cross-bars d. To these cross-bars are secured the stationary slides B, with which the movable slides C engage, the upper faces of these slides being in the plane of the lower faces of the grooves c in the side rails b.

D are end rails connected to the outer ends of each pair of slides C and corresponding in Serial No. 672,271. (No model.)

appearance to the side rails l), and E is a leaf secured to the slides C by swinging links e, which permit of its being lowered to rest upon the slides and to be carried thereby into the space beneath the top a.

Tables constructed as above described have heretofore been made capable of storing leaves sufficient in extent to enlarge the table approximately double the size of its stationary part. To obtain a greater extension, however, it is necessary to store the leaves in more than one tier, and as heretofore accomplished this is objectionable, inasmuch as the depth of the side rails is considerably increased, which gives a heavy and clumsy appearance to the table and impairs its salability. To overcome this objection, I have devised the following construction: The grooves c in the side rails Z9 are made of a width greater than double the thickness of the leaves, and the portion of the rail below the groove is only of sufficient depth to equal the thickness of the slides B and C, or it may be-even of lesser depth. The cross-bars d, which support the slides, do not extend completely across the space between the side rails, buttare cut off at a sufficient distance back to hide their ends from view. These cross-bars areV then connected to the side rails by anglebrackets f, preferably formed of metal, one wing of each being secured to the upper face of said cross-bar, while the other wing is secured to the inner face ofthe side rail. This forms a firm connection, which is completely hidden from view by the side rail. At the outer ends of each set of slides is secured a leaf E, which, as before described, is connected to said slides by the swinging links e. These leaves are something less than half the width of the top a, so that their inner edges do not extend quite to the center.

F is a leaf supported on the slides, but not connected therewith, and which I shall tl1ere fore call the detached leaf to distinguish it from the leaf E. This leaf is adapted when the table is fully extended to be placed between the leaf E and the stationary top d, and when stored to be arranged above said leaf E beneath said top.

At its inner edge the leaf F is provided with blocks Gr, secured thereto and resting on the slides C, the thickness of these blocks G ICO being preferably just a trifle greater than the thickness of the leaf E. The blocks G are provided with flanges g, projecting down beside the sides of the slides C and preferably slightly beveled or inclined. The blocks are also preferably provided with the outwardlyextending tongues h, adapted to engage with the spring-jacks t' on the under face of the top a.

II are blocks secured to the top of the slides C a short distance beyond the inner edge of the leafE and of the thickness ofthe blocks G.

I are blocks or stops secured to the sides of the slides and adapted to strike against the flanges g of the blocks G when the slides are drawn outward.

The arrangement of parts just described is such that when in the position shown in Fig. l the leaf F rests upon the blocks H and G, which raises its bottom face just above the top face of the leaf E, Then the slides are drawn out farther, the leaf F will be carried with them into the position shown in dotted lilies at X in Fig. 3, and when the slides are pushed in the leaf E will slide beneath the leaf F, as shown in Fig. 2.

In order to hold the leaf F from being drawn out with the leaf E in the first outward movement of the slides, I provide a lock for holding it intemporarily, preferably consisting of the spring-bolt J, arranged in a block K, located in the groove c of each side rail l), or it maybe placed in the stationary slide B, said bolt engaging with the recess 7' on the under side of the leaf F. The outer end of the block K is inclined at l to guide the leaf up into engagement with the bolt. The leaf F is engaged with the bolt .I when the slides are pushed in, the block II striking against the outer edge of the block G and forcing the leaf positively into engagement with the bolt. \Vhen the slides are drawn out, this lock will hold the leaf F from movement until the block I strikes against the blocks G and forces the leaf out of its engagement with the lock. The block K also serves to hold the leaf F against the upper face of the groove e, so as to hold the outer edge of said leaf clear from the leaf E when the latter is moved ltheren nder.

'l`o place the leaf F in position in the tabletop after the slides are drawn out and the leaf E is swung up into its raised position, the leaf F mustl be raised and the tongues 7i engaged with the spring-jacks e'. In order to facilitate this operation as well as to hold the leaf F securely in its raised position, I preferably provide the hinged posts L, pivotally secured beside the blocks G above the slides and adapted when the leaf F is raised to swing into an upright position and hold the inner edge of said leaf on a level with the top d, the outer edge having been first raised and rested upon the tongues 7s on the leaf E. These posts L are preferably provided with the points m on their lower ends, which prevent them from slipping on the slides. To

lower the leaf, it is pushed slightly inward, when the posts L will turn down into a horizontal position and at the same time carry the leaf F inward sufficientlyto be clear of the leaf E, when it also is turned down. I preferably place blocks n, projecting beside the tongues 7s, on the leaf E, which will strike against the edge of the leaf F should the latter not have moved sufficiently far inward and will push it out of the path of the tongues 7c. It will be seen that in a table constructed as above described the side rails may be of minimum depth, as no carrying-strips are necessary between the two tiers of leaves, and on account of the angle-bracket connection between the side rails and cross-bar it is not necessary to extend said rails downward farther than the bottom of the slides.

rlhe manner in which I unite the slides to the end rails D is shown in Fig. l, and consists of forming a tenen on the end of the slide and a corresponding groove in the end rail and then securing the two firmly together by a single screw 0,passing diagonally through the slide and tenen and into the end rail.

Before fastening together the parts are glued, and as the screw passes through the tenon and strikes the face of the groove at an angle it will draw the parts firmly together before it will enter said face, thus making a good contact between the glued faces and forming a very simple and effective securing That I claim as my invention is I. In an extension-table, the combination with the slides, a leaf attached to said slides, a second leaf detached from said slides and supported and carried thereby and means for holding` the detached leaf in such a manner as to permit of the attached leaf passing thereunder when in stored position, substantially as described.
