To all whom it may concern:

Be it known that I, CHARLES J. BROWN, of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Knockdown Extension Dining-Tables, of which the following is a specificatlon.

This invention has relation to extenslon dining tables which are provided with a pedestal and with a top made in separable sections to receive between them one or more removable intermediate leaves, and it has for its object to provide, first, for the total separation of the top sections from the pedestal, and, second, for limiting the separating movement of the top sectlons so as to locate said sections accurately in dilferent positions with respect to the pedestal to receive between them one or more intermedlate leaves.

In carrying out the present invention, I employ a pedestal which 1s substant1ally 1ntegral, c'. e. is not formed in separable sections, and a permanent top which consists of two sections slidably connected to the pedestal so as to be separable therefrom. The top sections are movable with respect to the pedestal toward and from each other, being connected to the pedestal by telescoplc sup ports comprising guides permanently attached to the pedestal and slides permanently attached to the under sides of the top sections. The slides and guides are provided with coacting stops which serve to limit the distance of separation of the top sections and to locate them in difierent predetermined positions with respect to the pedestal, so that the entire top-augmented by additional leaves-will be centered with the pedestal. The said tops are further so positioned with respect to the table-top sections that they are rendered accessible for operation when the top sections are separated a short distance.

On the accompanying drawings,Figure 1 represents in plan view a table embodying the invention, one set of slides being shown in section to illustrate the spring stop pins. Fig. 2 represents a vertical longitudinal section of the table. Fig. 3 represents a cross section through the table top.

Referring to the drawings, the table is represented as consisting of a pedestal 10,

which may be of any desired configuration, and which has supporting feet 11. The pedestal consists of a single unitary non-separable structure, and to the top thereof are secured by screws or other permanent fastenings the plates or blocks 12 which are let into sockets as shown in Figs. 1 and 2. Extending transversely of the table across the top of the pedestal are secured the parallel cross bars 13 13 which are attached by permanent fastenings to the upper end of the pedestal and to the blocks 12 12. The pedestal blocks and cross bar thus form a permanent support for the table top.

The table top consists of two sections 14 15 which, when contracted, form either a square, or a circle as shown in Fig. 1, but which may be moved apart or separated to receive one or more additional leaves and thus extend the table. The top sections are movable not only with respect to each other but also with respect to the pedestal, and they are detachably connected to the pedestal by telescopic supports which enable them to be separated far enough apart so as to completely disengage themfrom the pedestal. The telescopic supports comprise parallel guides 16 16, which are permanently secured upon and across the end portions of the cross bars 13 so as to extend longitudinally of the table, and slides 17 17 18 18 attached to the under sides of the sections 15 1 1 respectively by permanent fastenings such as screws. Each of the said guides is formed with dove-tail grooves on its sides extending from end to end thereof as shown in Figs. 1 and 3. The slides are formed with complemental tongues, the slides 17 17 being located between the guides, and the slides 18 18 engaging the outer sides of said guides. The guides and slides lack the usual limiting stops with which extension table slides have heretofore been uniformly provided to prevent the disconnection of the several slides. They are, however, provided with limiting stops which may be manipulated so as to permit the separation of the top sections and slides from the pedestal and guides. These manually operable stops may be made in any convenient way and possess any desirable construction, but, for the sake of simplicity and ease of operation I preferably employ spring-pressed pins extending through the slides and adapted to engage stop shoulders formed on the guides. As shown in Fig. 1, each stop pin 19 is passed laterally through an aperture in the slide, and has a beveled end which is forced by a spring 20 to engage stop shoulders formed by making notches in the sides of the adjacent guide. The springs are held in place by cover plates or escutcheons 21, and the pins have heads by which they may be grasped to withdraw them from engagement with the stop shoulders. The stop pins in the slides 17 1'. have their heads on the inner sides of said slides, and those on the slides 18 18 have their heads on the outer sides thereof.

It will be noticed, by an examination of Fig. 1, that the stop pins carried by the several slides are located on the portions thereof which project beyond the straight or inner edges of the top sections to which said slides are respectively attached, and are also located adjacent said inner edges, so that a slight opening movement of said sections will expose the stop pins for manipulation, and hence it is not necessary to reach from the sides underneath the top sections to operate said stop pins. v

For coaction with each stop pin are preferably two or more stop shoulders (two only being shown) as indicated at 22 23. The stop shoulders 22 are all located at equal distances from the median vertical transverse plane of the pedestal, and those on one side of said plane are at a distance from those on the other side, substantially a little greater than the width of a single extension leaf, so that, when the top sections are drawn apart, they will be stopped by the engagement of the pins with the shoulder 22 in exact position to receive the extension leaf between them and will properly balance on both sides of the pedestal. The shoulders 23 are likewise so located that, when the top sections are still further separated (after the stop pins are withdrawn to permit such separation), said top sections will be stopped and positioned accurately to receive two extension leaves between them. Of course I may provide additional stop shoulders so as to locate the top sections for three or more extension leaves, this depending upon the size of the table and the length of the slides and guides.

The stop shoulders are preferably formed by a beveled face terminating in an abrupt shoulder, and these bevel faces coeperate with the beveled end of the pins 19 to permit the top sections to move toward each other without interruption. A separating movement of the top sections is limited, however, by the pins coming in contact with the abrupt portions forming the shoulders and further separation is prevented until the pins are withdrawn.

Any convenient locking means may be employed for securing the top sections together when the top is contracted to normal size, I have shown a lock, consisting of a latch 24 carried by the section 15, and arranged to be engaged with the catch 25 on the under side of the top section 14 by the operation of a handle 26. This lock need not be described in detail as it is illustrated and explained in the United States patent to E. L. Marston, No. 935,608, dated September 28, 1909.

The ends of the guides are provided with the usual fixed stop pins or dowels 27, which engage grooves 28 in the outer ends of the guides to limit the inward movement of the top sections so as to center the contracted top with respect to the pedestal.

A table having the knock-down co11struction herein described, possesses marked advantages over those in which the top is permanently connected to the pedestal by fastenings such as screws and belts, or in which the telescopic supports are permanently connected to the pedestal and top sections respectively, since I obviate the necessity of a large portion of the storage space which has heretofore been used in show rooms and warehouses or packing rooms for the reception of tables. The top and pedestal need not be assembled until they are delivered into the room of the customer, and hence they take up but little space in cars and vans, and are easily carried or moved up or down stairs. Furthermore, the user may, by detaching the top, easily move the table through a door from one room to the other.

Having thus explained the nature of my said invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, what I claim is:

A knock-down pedestal extension table comprising a non-separable or integral pedestal, parallel supporting bars extending transversely of the table and secured to the top of the pedestal, parallel guides each secured to said supporting bars and at right angles thereto, the ends of said guides projecting beyond both sides of each supporting bar, said guides having notches spaced predetermined distances from a vertical transverse plane in the center of the pedestal, a table top formed of two separable sections, parallel slides carried by each section,

the slides of one top section being engaged with and guided by the inner faces of said guides, and the slides of the other top section being engaged with and guided by the outer faces of said guides, when the table is assembled, automatically operated stops carried by said slides and adapted to en age said notches to muse said top sections to be In testimony whereof I have aflixed my located at the same distance from the said signature, in presence of two Witnesses. plane, said stops being movable to permit the CHARLES J.
