EXTENSIBLE ROUND-TOP TABLE.
SPECIFICATION forming part of Letters Patent No. 722,577, dated March 10, 1903.
Application filed March 13, 1902. Serial No. 97,976. (No model.)
T at whom it may concern..-
Be it known that I, EDWARD B. GREGORY, a citizen of the United States, residing at Detroit, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in Extensible Round-Top Tables; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
This invention relates to new and useful improvements in extensible round-top tables; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims.
The object of the invention is to provide an extensible round-top table in which the arrangement is such as to enable the table to be extended diametrically and yet maintain a perfectly true circle at any degree of extension.
The above object is attained by the structure illustrated in the accompanying drawings, in which Figure l is a perspective view of a table involving my invention, showing a partial extension of the bed thereof. Fig. 2 is adiametrical section through the table. Fig. 3 is an enlarged vertical transverse section through one of the extensible slides and a portion of the table-bed, as on line 3 3 of Fig. 2. Fig. 4; is a plan view of the table, showing one half thereof extended and the other half closed in its normal position. Fig. 5 isa plan view of one of the hinged top-sections adapted to fit upon and extended between the extensible divisions of the bed when the table is closed. Fig. 6 is a plan view of a set of hinged leaves employed to level the top of the table-bed and to extend between the extensible divisions of the table when extended. Fig. 7 is an edge view of the leaf-section shown in Fig. 6 folded together. Fig. 8 is a side and screws into a tapped plate in the under face of the leaf-sections to hold said leaves in position and secure the extensible divisions of the table against movement. Fig. 5 5 10 is a plan View of the table with the top removed, showing cap-plate and radial bars.
As will be seen on referring to the drawings, the bed of the table is divided into four quadrants 1,which when placed together form a complete circle. The inner ends of these quadrants of the table-bed are supported upon a central leg 2, carrying a cap-plate 3 and having attached thereto four radial bars 4, whose outer ends are secured to the stationary half 5 of the separable legs which support the outer edge of the table-bed. These rigid bars 4 constitute a sort of a frame upon which the table-bed is mounted and upon which the quadrants of the table-bed are movable. In the side of each of the bars 4 is a way 6, adapted to receive the dovetailed slide 7, (see Fig. 3,) carried upon one face of the slide-bar 8. Upon the opposite face of the slide-bar is a dovetailed slide 9, adapted to slide in a way 10 in the inner face of the slide-bar 11, attached to the movable section 12 of the outer legs. The slides just described are the ordinary extensible slides and need not, therefore, be set forth with reference to their specific details. The quadrants of the table-bed are mounted upon the movable slide-bars 11, so that when the said bars 11 are drawn outwardly the divisions of the table-bed are separated as said divisions move outwardly in a diametrical direction. Occupying the central portion of the divisions of the table are the raised quadrangular sections 13, which are in the form of trapeziums and whose acuminated points 14 ter- 0 minate at the outer margin of the sections of the, bed.
When the table is closed, the raised quadrangular sections 13 describe a four-point star, and the space between the points of the 5 star is filled by the segmental top-sections 15,
as shown upon the unextended portion of the table in Fig. 4. The top-sections 15 are hinged together at the center to enable them to be folded when notin use and are of such 10o thickness as to correspond with the fixed sections 13, so that when placed upon the table in its closed position said removable topsections 15 raise the surface of the table between the points of the star to a level with the remaining portion, thereby presenting an even top surface.
To provide for filling the gaps between the extensible divisions of the table when in an extended position, hinged leaf-sections 16 of peculiar shape are employed with a curved outer margin, as shown in Fig. 6, and which are provided in their opposite edges with angular recesses 17, which coincide with two of the sides of the trapeziums occupying the center of the extensible divisions of the table, while the wings of said leaves lie upon the surface of the table-bed between the raised sections, their body portions spanning the gap between the separated divisions and their inner points meeting in the center of the table upon the plate 3, in which position the surface of the table is rendered level and smooth and the contour of the extended circle is completed between the points 14 of the raised central portions, as clearly shown in Fig. 4. In order to bind the parts firmly together when the table is extended, the hinged leaf-sections 16 are provided on either side of the hinge-joint 18 with plates 19, let into the under face thereof and tapped to receive a set-screw 20, as shown in Fig. 9. This setscrew passes through the bed of the table and screws into said plate, thereby firmly tying all of the movable divisions together and at the same time maintaining the hinged leafsections in position.
It will be understood that any degree of extension may be attained and the contour of the table preserved in a perfect circle by using various sizes of the insertible leaf-sections, it being understood that a different size of the leaf-sections must be employed for each change in the tables diameter. In actual practice, however, it will probably be found sufficient to have but two sizes of said leaf-sections to provide for the fullest extension of the table and for an extension thereof midway between its maximum extension and its closed position.
The hinges 21, (see Fig. 7,) which are employed to unite the members of the removable leaves, are mounted upon the under face thereof, so that the leaves may be opened outwardly when placed upon the table, thereby allowing the hinges to brace the leaf-see tions when in position and render the top of the table firm, as clearly shown in Fig. 8. The segmental top-sections 15 when in position upon the closed table are in like manner secured by the set-screws 20, which pass upwardly into plates in the under face thereof, as described with reference to the leafsections 16. It will be understood that when the table is extended the segmental top-sections are removed before the leaf-sections are placed in position. When the table is closed and the segmental top-sections are in place, they serve with the aid of the thumb-screws to bind the movable divisions of the tablebed together.
Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In an extensible round-top table,the combination of the extensible segmental divisions adapted to move diamatrically to extend the tables diameter, leaf-sections adapted to span between and unite the movable divisions of the table, a portion of the table depressed to receive the leaf-sections which lie therein, said leaf-sections having a curved margin concentric with the circle of the table, the extremities of the adjacent leaf-sections meeting at the center of each of the extensible divisions.
2. In an extensible round-top table, the combination of the segmental divisions of the bed adapted to move diametrically to extend the tables diameter, a portion of the top of the bed being depressed, leaf-sections having wing portions extending onto the depressed portion of the bed of said movable divisions and a body portion spanning the space between them, said leaf-sections being removable and adapted, when in position, to level the top of the table.
3. In an extensible circular table, the combination of a table-bed having diametricallyextensible divisions, each division having a raised portion occupying the center thereof, and segmental top-sections adapted to lie between said raised portions when the table is closed to raise the plane of the intervening surface of the bed to the height of that of said raised sections, the outer edge of said top-sections describing the arc of the tables circle.
4. In a circular extension-table, the combination of the table-top divided into extensible segmental divisions adapted to move diametrically to increase the tables diameter, leaf-sections having a body portion adapted to fill the gap between the extended divisions and lateral wing portions adapted to extend onto the surfaces thereof, and means for securing the wings of said leaves onto the surface of the opposite movable divisions of the table to firmly secure the parts together when extended.
In testimony whereof I sign this specification in the presence of two witnesses.
