Application filed September 23, 1908.

To all whom it may concern:

Be it known that I, ADDY S. EL-Kounr, a citizen of the United States, residing at Duke, in the county of Jackson and State of Oklahoma, have invented certain new and useful Improvements in Extension-Tables, of which the following is a specification.

The invention relates to improvements in extension tables.

The object of the present invention is to improve the construction of extension tables, and to provide a simple and comparatively inexpensive extension table, designed for use in public and private dining rooms and various other places and equipped with means for enabling it to be instantly adjusted to make it either larger or smaller to accommodate the desired number of persons.

A further object of the invention is to provide an ext nsion table of this character, capable of djustment without taking oil the table cloth, or removing an electrolior, candelabra, or other ornamental center piece.

' With these and other objects in view, the invention consists in the construction and 11 vol combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hcrc to appended, it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any ofthe advantages of the invention.

In the drawings :Figure 1 is a perspective view of an extension table, constructed in accordance with this invention. Fig. 2 is a reverse plan view of the upper portion of the Fig. 3 is a vertical sectional view on the line 33 of Fig. 2. Fig. 4 is a detail vertical sectional view of the central portion of the table. Fig. 5 is a plan view of the upper portion or bed of the supporting frame, illustrating the manner of mounting the motor and the gear ing for simultaneously adjusting the movable leaf sections.

Like numerals of reference designate corresponding parts in all the figures of the drawings he table comprises in its construction a supporting frame including a central vertical hollow column 1, a rectangular top portion or bed 2 and legs 3, extending from the lower end of the hollow column.- The hollow col- Speeification of Letters Patent.

umn and the legs, which may ac constructe l of any suitable material, are preferably of an ornamental character, and the horizontal top portion or bed 2 is composed of side bars or rails, diagonal braces 3 and a platform The hollow column is provided at its up er portion with a spider 5, consisting of diagonally arranged arms receiving the braces 3 and secured to the lower faces thereof. The upper end of the hollow column is provided with a cap 6, having a central threaded opening 7 for the reception of the upper end of the lower section 8 of a vertical tubular conduit or member, which is also provided with an upper section 9.

The lower end of the lower section is threaded and engages a threaded aperture 10 of a nut or plate 11, designed in practice to be rigidly connected with the lower end of the hollow column. The upper end 12 of the lower section of the central tubular conduit is extended above the cap 6 and screwed into the lower end 13 of the upper section 9, which is .interiorly threaded. The upper section 9 is provided at its upper end. with an enlargement or head 14-, and it forms a bearing for a rotary sleeve 15, provided at its upper end with a pinion 16 and connected at its lower end with a horizontal worm wheel 17. The worm wheel meshes with a worm 18 of a horizontal shaft 19, journaled in suitable bearings 20 and equipped with a spur gear 21, which meshes with a pinion 22 of an electric motor 23. The platform e supports the electric motor and the bearing 20, the motor and the bearing being secured by screws, or other suitable fastening devices to the platform. The wires 24; and 25 leading to the motor pass upward through the central tubular conduit and enter the same at the lower ed thereof, and they extend through registering apertures 26 and 2. of the upper portions of the lower section of the conduit and the tubular column. The

rotor furnishes power for operating the gearing to simultaneously adjust movable leaf sections ofthe top of the table.

The top of the table is composed of a central relatively fixed leaf section QSand four adjustable or extensible leaf sections, each composed of a wooden supporting member 29 and an overlapping relatively thin sheet metal member 30. The wooden supporting members are located at the corners of the top of the table, and each overlapping sheet metal member is secured to the end of the inner transverse edge of its companion corner member, and it extends along the adjacent side of the table and overlaps the relatively thick wooden supporting member of the contiguous leaf section. The overlapping member 30 is provided at its inner transverse edge with a substantially L-shaped attaching flange 31, secured by screws 32, or other suitable fastening devices to the wooden member 29, and it fits against the adjacent edge and the lower face of the said member 29. The upper face of the relatively thin member of the leaf section is located above the upper face of the relatively thick supporting member 29, so that all of the rela tively thin members of the leaf sections are disposed in the same horizontal plane, and have their upper faces in flush relation, when the table is closed, as illustrated in Figs. 1 and 3 of the drawings. The outer marginal edge of the relatively thin member is equipped with a tubular guide or way 33, substantially rectangular in cross section and consisting of an outer vertical wall, a horizontal bottom, and a vertical flange 34, extending upwardly from the inner edge of the horizontal bottom wall and fitting within a longitudinal groove 35, formed in the lower face of the relatively thick member that is overlapped by the said relatively thin member. The contiguous outer marginal portion of the relatively thick member is arranged within and embraced by the hollow guide of the relatively thin member, whereby the leaf sections of the top of the table are slidably interlocked with one another. l Yhen the table is adjusted to change the size of the top, the relatively thin member of one leaf section slides over the relatively thick member of the contiguous leaf section. The slidable interlocking of the adjustable leaf sections of the top maintain the said leaf sections in their rectangular relation.

The extensible leaf sections are simultaneously moved inward and outward and are guided in such adjustment by means of the diagonal rack bars 36, arranged in pairs, the members of each pair being disposed in parallel relation. The rack bars, which are provided at their inner edges with teeth, mesh with the pinion 16, as clearly illustrated in Fig. 3 of the drawings. The relatively thick wooden sections are equipped at their inner corners with fixed inner brackets 37, preferably L-shaped in cross section and consisting of a horizontal attachin flange and a depending vertical flange. The depending vertical flange, which is rigidly secured at 88 to one of the members of the contiguous parallel rack bars, is provided with a guide opening 39, receiving the other member of such pair of rack bars. By this construction, each inner bracket is fixed to one rack bar and guides the adjacent rack bar. The inner bracket 37 is connected by a diagonal guide rod 40 with an outer corner bracket 41, secured to the outer corner of the relatively fixed member and provided with a depending lug to which the outer end of the guide rod 10 is attached. The guide rods 40 pass through openings 42 in the corners of the upper rectangular top portion or bed of the supporting frame of the table. By this construction, the extensible leaf sections of the top of the table are simultaneously adjusted inward and outward.

The relatively fixed top section 28 is secured by screws 43, or other suitable fastening devices to the upper end of the upper section 9 of the tubular conduit, which is provided with an interiorly threaded terminal portion 44, piercing the relatively fixed section 28 and interiorly threaded to receive an electric light 45. The

wires

46 and 47, leading to the electric light, extend upward through the tubular conduit. The outer edges of the relatively fixed central leaf section 28 are preferably beveled, as shown, and while the section 28 is exaggerated in thickness in the accompanying drawings, it may be made comparatively thin, so that the table cloth will present a smooth appearance. The central section overlaps the relatively thin members of tne adjustable leaf sections, as clearly shown in Fig. 1 of the drawings.

The table cloth 48 is designed to be provided with a central aperture to permit the base of the electric light to be introduced into the socket formed by the terminal portion 44 of the tubular conduit of the supporting frame of the table, and the corners 49 of the table cloth are designed to be weighted with a small bag of shot, or other suitable means. By this construction, the table cloth will hang smooth and adjust itself to the table and will permit the same to be varied in size without necessitating the removal of the cloth. The current to the electric motor is designed to be controlled by a button, or other suitable switch, and the motor will enable the table to be instantly made larger or smaller as desired. The diagonal movement of the leaf sections will cause the relatively thin members to slide on the relatively thick overlapped members.

Although i have illustrated an electric motor for operating the extensible leaves, any other suitable means may be employed for performing this operation.

Having thus fully described my invention, what 1 claim as new and desire to secure by Letters Patent, is
