CHANGEABLE SUPPORT FOR TABLE-TOPS, 84,0.

SPECIFICATION forming part of Letters Patent No. 662,136, dated November 20, 1900.

Application filed June 25, 1900 T0 at whom it may concern.-

Be it known that we, EDWARD W. SAR- GENT, residing at Osh I em 0, and CHARLOTTE C. DOVER, residing at Kalamazoo, in the county of Kalamazoo, State of Michigan, citizens of the United States, have invented a new and useful Changeable Support for Table-Tops, &c., of which the followingisa specification.

The object of this invention is to construct a changeable support for detachable table-tops or any other device or article which it is desired to temporarily support, said support being capable of folding up and being opened and adapted to stand at different heights, according to the way it is opened, all as is more particularly set forth below.

In the drawings formingapart of this specification, Figure 1 is an elevation of the sup port open and supporting a detachable table top or board at the lowest location. Fig. 2 shows the support supporting the detachable table top or board at the highest position; Fig. 3, a section on line 0 c in Fig. 2 looking from a point above, and parts being broken. Fig. 4 shows the support folded forcarrying, shipping, or storing; and Fig. 5 is an enlarged section of one of the bars forming the legs proper of the support on line 6 e in Fig. 4:.

Referring to the parts of the drawings pointed out by numerals, 6 6 and 7 7 are the bars composing the centrally fulcrumed or pivoted changeable or adjustable legs of the support. These legs-bars are all made alike and four are used in each support. They have a front surface 8, an inner surface 9, opposite and narrower than the surface 8, and two oblique or beveled edges 10, (shown especially clearin the cross-section in Fig. 5,) this being shown in full size, but of course the size can vary accordingto the strength needed. These beveled edges 10 rest against each other, as in Fig. 3, holding the leg- bars b 6 and 7 7 at oblique angles after the leg-bars have been swung on their pivots 11 and 12 to open the support to its used position. In

this case each set of two leg-bars of the entire four form an X in side elevation when looking at the support from any of the four directions, as in Figs. 1 and 2.

Serial No. 21,495. (No model.)

10 of the leg-bars admit of a more satisfactory and firm fit and increase in the contacting surfaces of the oblique leg-bars when the support is open, and also the use of a smaller block to which they are pivoted, and hence lighter in weight than would be the case were the edges of the leg-bars not beveled, as at 10, but left at right angles to the sides Sand '9, in which latter case the contacting surfaces of the leg-bars when the support is open in its used position would be sharp corners which would quickly become indented by wear, and thus change the intended heights of the support in its two positions of use.

The end formation of the leg-bars 6-6 and 7 7 is as follows: One side corner at one end is beveled off at an oblique angle to the plane of the leg-bars, as at 15, and the opposite end corner atthe other end is formed the same as at 16, while the side corner opposite to 15 is beveled off at an oblique angle to the plane of the leg-bars, as at 17, and the opposite side corner at the other end is formed at 18, same as at 17, thus making the length ofthe surfaces 17 an 18 much less than the surfaces 15 and 16 are in length. This makes the difference in height according to the particular way or direction the support is opened. Figs. 1 and 2 show the support in its two adjustments, high in Fig. 2 and low in Fig. i, said leg-bars 6 6 and 7 7 being shown in Fig. 2 as reversed to opposite oblique angles from that in Fig. 1, by which means the bevels 15 rest on the floor in Fig. 1 and the upper bevels 16 support the detachable table-top at the upper end. The flooris shown at 13 and the table-top at 1%. This su pports the table-top 14 in its lowest position. In Fig. 2 the side corner oblique bevels 17 rest on the floor 13 at the lower ends of the leg-bars, and the oblique bevels 18 at the upper end support the detachable table-top 14 in its highest position. Observe that the angles 15 and 17 at the same end of the four leg-bars must be at right angles to each other and both of said angles at an oblique angle to the horizontal plane of the leg-bars, and the same in regard to the angles at the other ends of the leg-bars in order to accomplish the It will be observed that the beveled edges two specified results as to height and give a proper surface for the leg-bars and table-top to rest on.

In the folded-up condition of the support,

as in Fig. 4, the legbars are parallel with each other, and the device when thus folded can be easily handled and carried and will occupy little space in storing and shipping. Of course we make no claim on the capability of folding per se. Centrally between the leg-bars (5 b and 7 7 is a solid pivoting-block 19, Fig. 3, provided with integral pivoting projections extending out from each of its four sides at right angles thereto. Two of these projections are shown at 20 and two at 21. The set of leg-bars 6 6 are pivoted to the projections 20 and the leg-bars 7 7 are piv-- oted to the projections 21. 7

These supports will be found convenient for many uses, such as supporting detachably table-tops at social games, at picnics, and even for temporarily holding washtubs, and this at convenient heights in accordance with the height of the person,

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is-

The support, comprising the set of two legbars 7 and the set of two leg-bars 6, each legbar of the two sets being of asingle continuous piece and beveled obliquely at the edges as at 10, thus making one side 9 narrower than the other side 8, a central block 19, the sides 9 of the leg-bars fitting against the sides of the block and pivoted thereto, thus causing the beveled edges of the leg-bars to rest against each other when the support is open, the opposite side corners of the ends of each leg-bar being cut oif at angles 15 and 17 at one end, and at 16 and 18 at the other end, all said angles being oblique to the longitudinal plane of said leg-bars, the angles 15 and 17 being at right angles to each other, and the angles 16 and 18 being at right angles to each other, whereby when the oblique angles 17- rest on the floor, and the table-top rests on the oblique angles 18 at the then upper end of said leg-bars, the table-top is held in a higher position than when the leg-bars were opened in the other direction, substantial]; as set forth.

Intest-imony of the foregoing we have hereunto set our hands in the presence of wit nesses.
