EXPANDING TABLE.

Specification of Letters Patent.

Patented A-ug. 28, 1906.

Applicaticnfiled January 10,1905. Serial No. 240,501.

To all whom it may concern:

Be it known that I, MIoHELE GUeLIELMo DE SIMONE, of 37 Southampton Row, in the county of London, England, am in possession of an invention for Improvements in or Belating to Expanding Tables, of which the following is a specification.

This inventionrelates to expanding tables.

It is the'object of this invention to provide improved means whereby table of'circular shape can be readily expanded with considera ble increase of' area and; sitting capacity and without'dividing or unfolding the normal or closed table-top andstill retaining the circular shape.

The type of table to which the invention relates is that in Which leaves or sections are provided which are normally stored beneath the central member and are adapted to be adjusted around the latter when it is desired to expand thetable. According to my'invention the sections are adapted to be moved directly outward to their extended positions witho ut' requiring a vertical adjustment after being extended In cases where it is desirable to reduce the depth ofthe closed table-top some of the said sections may be slid directly under the dentralmember and lie between same and its support, while the other 'member'or members may be slid under thecentral'member'upon guides inclined downward toward the middle thereof, a slightverticalmovement ofthe central member being all that is necessary to allow the sliding member to pass thereby;

The edges of the central member or the table in its closed form which will be in more general use-than the other will preferably be fitted with a downwardly-extending rim in the form of an annulus or sections thereof separate from the top and-held up in position by springs, so that it will when the table is closed hide the sections stored thereunder, while the rim can be readily depressed to al low the sections to be pulled out when the table is to be enlarged.

The accompanying-drawings illustrate one form of my invention, and a modification thereof.

Figure 1 is an-elevation ofthe table in its closed or reduced form. Fig. 2 is a plan of Fig. 1 Figs. 3 and 4 are similar views to Figs. 1' and 2, showing'the table in its expand ed form. Fig. 5 is a plan with the table-top removed, and showing mechanical means for expanding the table. Fig. 6 is a sectional elevation of part of Fig. 5. Fig. 7

is a detail, and Fig. 8-is a detail showing the spring-pressed. rim.

Referring now to Figs. 1, 2, 3, and 4, a is the central circular member of the table supported by a central vertical pin b, sliding in a socket carried by the table-frame c, which is preferably supported on four legs (1 rZ,.which legs are disposed as near as convenient to the edge of'the circular member a.

The movable sections or extension-pieces are shown as four in numberviz. ,ff f" f arranged in two pairs, one pair f f 2 being movable toward and from each other along one diameter of the table-top, and the other pair f 3 f 4 being similarly movable toward and from each other along another diameter of the table-top crossing the first-named diameter at right angles, as seen in plan. Two bars 6 e are provided which form guides for the two movable sections f f and which are themselves connected by two bars e e, that form guides for the .two sections f f. Two ofthe said guide-barsnamely, e e are horizontal and the others e e are inclined downwardly and inwardly, so as to leave room for the sections f f f f to rest beneath the central member a. For sake of strength the guide-bars e e are shown as made of two members suitably spaced apart. The outer movable sectionsf f 2 f 3 f which form an annulus around the central member a, are divided on a line 9 running parallel with one set of guide-bars, whereby the sliding-movement of the members f f 2 may be lengthwise of the dividing-line g. Further, theabutting faces of the sections on the line g are formed -with tongues and grooves, whereby said-faces are more securely locked and'form amore stable joint when the table isexpanded. Fig. 7 shows such an arrangement of tongue h andgroove h.

In operation assuming the table to be closed, with the two sections f f resting on the inner ends of the incline guides e e and the other two sections f f resting on the horizontal guides e e and supporting the central member a, which. is kept in position by its central socket and pin 1), first, the horizontal sections f f are pulled out beyond the centralmember a, andthe latter is then allowed to move down until its surface is on a level with the surface of'the sections f f Then-the two sectionsff are slid up the inclined guides e e and past the edges of the central member a, which is slightly position.

raised for the purpose. In this sliding movement the tongue it will engage and slide into the groove h, and the whole table is now a complete and enlarged circular table, with a top on one level and firmly supported. (See Figs. 3 and 4.)

The increased area is considerable; but what is more important the circumference and the consequent seating capacity is also increased.

If a circular rim is used, such as indicated I at j, Figs. 1 and 3, it is preferable to mount the same so that it can be depressed while the sections are slid out. This movement may be accomplished by mounting the rim on springs, as indicated at k, which springs will serve to keep the rim pressed up tight in the position shown in Fig. 1, but may be readily depressed to the position shown in Fig. 3 for convenience of drawing out the sections. 'Where foursections are used, it is preferable 'to connect the opposite sections-namely, f f orf 3 f by levers or slides so arranged that the pulling out of one 'will push out the opposite one. Suitable stops will be provided to limit the movement of the sections and determine their correct position. Such an arrangement of levers is shown in Figs. 5 and 6, where, however, additional means are shown for mechanically operating the sections from the center by means ofa handle. In these figures the sections f f are connected by levers n n to a central disk or lever n, while the sections f 3 f are connected by similar levers 0 0 to another dlsk or member 0. The disks n and 0 .are mounted. on suitable bearings and are formed with teeth go around their periphery. The disks n and 0 are suitably spaced apart, so that a sector or mutilated toothed wheel Q may gear with one or other of them. Said wheel g is mounted on a horizontal shaft 7, extending to some convenient spot on the tahie-frame and fitted with a squared end, to which a handle may be fitted for rotating same. In use the parts will be expanded from the position shown in Figs. 5 and 6 by rotating the spindle r, rotation of which will cause the wheel q first to engage and rotate the disk 0 and move the sections f 3 f 4 out of The tooth part of the wheel Q will then engage and operate the disk n in a similar manner and extend the sections f f Meanwhile the gap in the wheel 9 will leave the disk 0 stationary. In order that the central member a may be raised at the proper time, the spindle r is fitted with a cam s, which serves to raise same at the proper time and to allow the sections to pass thereby.

If desired, other means than the handle shown may be provided for operating the spindle 7. It is obvious that the outline of the table may be other than strictly circular, although this shape is preferred. The sections may be more than four in number, and

each section may be formed in more than one piece, if desired. The sections may be stored in any suitable number of planes.
