EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 333,501, dated January 5, 1886.

Application filed August 12, 1884. Serial No. 140,307.

To aZZ whom it may concern.-

Be it known that I, HEINRICH F. BURMES- TER, a subject of the Emperor of Germany, residing at Chicago, in the county of Cook and State of Illinois, 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 an improved extension-table.

The object it has in view is to improve the general construction, and especially the leaf supporting and adjusting parts thereof, it being designed as an improvement on the table described by me in an application filed July 14, 1884, Serial N 0. 137,734.

To the accomplishment of the above, the invention consists of the novel arrangement of the central support of the table, to which the central leg or legs are secured with respect to the slides or extension parts of the table; and the invention further consists of the novel arrangement and mode of adjusting the leaves, as will be fully described and claimed.

Reference willbe made to the accompanying drawings, in-which Figure 1 is a longitudinal sectional View through a section of the table; Fig. 2, acrosssection thereof; Fig. 3, adetail 'in cross-section; Fig. 4, a detail perspective of parts, and Fig. 5, a perspective of the table extended.

Like letters refer to like parts in each view.

A A represent the end sections ofthe table,

- which form the table proper when no leaves are in use. Each end section is supported upon suitable legs, B. One section A is provided with two strips or bars,b,one upon each side, and each provided upon its inner face with a dovetail projection, 0, adapted to enter a corresponding]y-formed groove, 0, formed each in one face of a slide, a. Upon the opposite face of each slide a there is formed a similar projection, f, arranged to enter each a suitable grove, 0', formed in slides c. Slides 0 are also formed with projections 19, which enter and move in grooves (1, formed in strips or bars (1, secured to the opposite end section of the table.

By the arrangement of parts as thus far described it will be seen that provision is made for the extension of the table, it being under- (N0 model.) I

stood that the several slides are provided with any suitable stops to prevent their separating.

C represents the central leg of the table, which is secured to a cross bar or beam, h. At each side edge of bar h there is provided an angle-iron, g, bent inwardly at its upper and lower ends. At their upper ends these irons g are secured to the slides a, there being sufficient space between such slides and irons to allow of the free movement therebetween of slides orstrips b. This arrangement is clearly shown in Figs. 3 and 5 of the drawlugs.

In Fig. 4 I have shown in detail suitable cross-bars, adapted to connect each pair of slides and arranged to support the leaves a in the table-frames. These connecting-bars are designated by the letter k, and are provided at each end with an ear,l, through which suitable openings are formed for the passage of screws for securing them to the slides. It will be understood that each set of slides a b c, 810., is connected by two of these cross-bars; and,further,it will be understood that because all the slides are arranged on the same horizontal plane, it' is necessary to prevent the several leaves,when notin use, from coming into contact, to have the ears of different crossbars of different lengths those supporting the leaf which is to rest in the highest plane being the shortest and the length gradually increased until the lowermost leaf is reached. This arrangement is clearly illustrated in Figs. 2 and 5 of the drawings. Pivoted to the inner face of each cross-bar 7c is an arm, m, to the upper end of which the leaves are pivoted. Each cross-bar is provided with a lug, n, to limit the movement ofarins m, and atthe same time form an additional support for such arms when the leaf is in use. Each cross-bar is is also provided at points near each end with a suitable lug, q, upon which theleaf rests when In an extension-table, the combination of 1 end sections, A, slides b, a, c, and d, cross- The operation of the arms m pieces h, and angle-irons 9, said irons connected at one end'to cross-piece h and at theother end to slides a, and so constrncted as to allow 15 slidesb to move between them and slides a, as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
