To a/LZ whom it may concern:

Be it known that I, JOHN W. LINDoW, a citizen of the United States, residing at Marine City, in the county of St. Clair and State of Michigan, have invented new and useful Improvements in Extension-Tables, of which the following is a specification.

My invention pertains to extension-tables of the type in which provision is made for storing supplemental top sections under the top of the main section; and it consists in the novel and advantageous combinations of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a longitudinal vertical section showing my novel table as extended to the full extent. Fig. 2 is a similar view illustrating the table as contracted. Fig. 3 is an inverted plan view illustrating the end extensions of the table extended. Figs. 4 and 5 are transverse sections taken on the lines 4 4 and 5 5 of Figs. 1 and 2, respectively. Fig. 5 is a perspective view of the right-hand end extension. Fig. 6 is a detail section illustrating the relative arrangement of the tongues and grooves of complementary slides. Figs. 7, 8, and-9 are perspective views of supplemental top sections removed. Fig. 10 is a detail section of the top section shown in Fig. 9. Fig. 11 is an enlarged detail section taken through the top and one side iange of the main section. Fig. 12 is an enlarged detail inverted plan illustrating the manner in which the end bars of the end extensions are seated in rabbets of the side iianges of the main top, and Figs. 13, 14, and 15 are modifications hereinafter referred to in detail.

Referring by letter to the drawings, and more particularly to Figs. 1 to 12 thereof, A is the main section of the table. The said main section comprises a top ct, side ianges b, fixed to and depending from the top and having rabbets c in their ends, Figs. 3 and 12, and also having longitudinal shelves d on their inner sides at intermediate points of their height, and cross-bars e, connected to the lower edges of the flanges The top a and flanges I) arepreferably connected through the medium of angle-irons B, (best shown in Figs. 4,

5, and 11,) and the shelves Z are preferably `formed by metallic plates, as shown, which plates have depending lugs f extending through openings g in the depending portions of the angle-irons and resting back of said depending portions. When desired, however, angle-iron BQ having integral shelves J, Fig. 15, may be employed in lieu of the angle-irons B and shelves (Z without involving a departure from the scope of my invention.

The cross-bars e of the main section A serve for the connection of longitudinal slides C, which are braced by a cross-bar c and are provided with inner and outer longitudinal grooves Z and are also provided with tongues m at their ends. At its opposite ends the 65 main top a is provided with keepers D, Figs. 1 to 3. These keepers D are preferably metallic pieces connected to the top o, adjacent to the ends thereof, and bent downwardly so that their free portions rest below the under side of the top, and their ends are flush with tlie ends of the top.

E E are slides disposed at the inner sides of the slides C and having longitudinal grooves p, receiving the tongues m of slides C, Fig. 6, and also having tongues 2", movable in the inner grooves Z of said slides C, and F is a transverse wall fixed to the slides E. Each of the slides E is provided on its inner side with eight (more or less) lateral projections s, while the wall F is provided with recesses t; The said slides E and wall F constitute the leftend extension of the table. This left-end extension is similar to the right-end extension, except that the slides E of the latter are arranged at the outer sides of the slides C and have their lateral projections s on their outer sides.

G and H, Figs. 1, 7, and 8, are supplemental top sections complementary to the rightend extension, and G and H are corresponding supplemental top sections complementary to the left-end extension. These sections respectively comprise a top u and cleats o, fixed to the top and arranged to rest alongside the end slides. In the side of each of the cleats of the section G or G are inclined grooves w, arranged to receive the lateral projections on the end slides and having offsets at their upper ends, while in the side of each of the cleats of the section H or H are inclined grooves e, arranged to receive other lateral projections of the end slides. The sections G and G' are each further provided at one end of its cleats c with lugs a and at the opposite ends of said cleats with sockets b. The sections H and H are each further provided at the inner ends of its cleats with lugs c', arranged to enter the sockets b, and at the outer ends of the cleats with lugs d', arranged to enter the recesses t in a bar F, all as best shown in Fig. 1.

In the practical use of my novel table whenit is desired to use the supplemetal sections G G and H H', and thereby increase the length of the table, the sections G and G are disposed with their cleats on certain of the lateral projections of the end slides and their lugs a in the keepers D of top a, while the sections H Hl are arranged with their cleats on other lateral projections of the end slides, their lugs c in the sockets b' of sections G G, respectively, and their lugs d in the recesses "of the cross-bars F. With the parts thus relatively arranged it will be observed that the upper surfaces of the sections G G and H H' rest flush with that of the main section A and the several sections are interlocked, also that the walls F rest below and support the outer edges of the sectionsH and H. When a table of the length shown in Fig. 2 is desired, the'sections G and H are disengaged from each other, as are also the sections G and H', and are positioned on the end slides so that their tops rest directly on said slides, while the grooves in their cleats receive lateral projections on the said slides. With the sections G G and H H thus posiytioned relative to the slides the said sections are held on the slides in such manner that there is no liability of the sections being casually displaced. From this it follows that when the walls F are shoved toward the main ection A the sections G G and H H will be carried under the top a, and `hence out of sight and out of the way, Fig. 2, while the ends of the walls F will rest in the rabbets c of flanges b, and said walls will rest under the ends of the top a. When it is desired to use the sections G G and H H', the end extensions are drawn outwardly suiiciently far to enable the inner sections to clear the top a, when the sections are disengaged from the slides and the operation first set forth is carried out. When the end extensions are drawn outwardly as stated, the tongues of their slides bringing up against the tongues of the xed slides C will obviously prevent casual disconnection of the slides E and E from the slides C.

When desirable, vertical grooves we, Fig. 13, maybe provided in the cleats of the sections G G H H in lieu of the grooves before described without involving a departure from thescope of my invention.

When it is desired to omit the shelves Z or d before referred to from the table, the side ianges of the main sectionfmay be connected to the top thereof through the medium of angle-irons B2, one of which is shown in Fig. 14, or through the medium of any other suitable means.

The shelves d on the iianges I) of the main section A are designed to support four (more or less) supplemental top sections G2 when the latter are not in use, as shown in Fig. 2. These top sections G2 are identical in construction, and therefore adetailed description of the one shown in Fig. 9 will suffice to impart a definite understanding of all. The said section G2, Fig. 9, comprises a top u, cleats fu, preferably of sheet metal, hinged to the under side of the top u and having lugs a2 and sockets Z22, and springs c2, arranged to move the cleats to and normally hold the same at right angles to the top. When the several sections G2 are not in use, they are stored on the shelves el and between said shelves and the top a, Figs. 2 and 5, in which position the shelves w-ill serve to hold the cleats flat against the 'top.. When the sections G2 are removed from Linder the top a, the springs c2 will operate to move the cleats to a position at right angles to the tops, in which position the cleats may be arranged on lateral projections of the slides E E with their lugs and sockets interlocked, as shown in Fig. 1. In this Way a very long table may be produced, and yet when desired said table may be contracted to the extent shown in Fig. 2. To contract the table, the supplemental sections G G H H are placed with their grooves in engagement with the projections of the end slides, and the supplemental sections G2 are placed on the shelves CZ, Fig. 5, after which the end bars F are shoved inwardly into engagement with the ends of the main top a, as shown in Fig. 2. f

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the said embodiment. I do not desire, however, to be understood as confiningmyself Uto the said specific construction and relative arrangement of parts, as such changes or modilications may be made in practice as fairly fall within the scope of my invention as claimed.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
