LEAF-SUPPORT FOR TABLES.
SPECIEZGATION forming part of Letters Patent No. 339,427, dated April 6,1886.
To all wiwm it may concern:
Be it known that 1, CHARLES KADE, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Leaf-Supports for Tables, &c., of which the following is a specification, reference being had therein to the accompanying drawings.
This invention has for its object to produce a table-leaf support that is simple, strong, and durable, and that can be readily manipulatcd.
The first part of my invention consists of a table-leaf support composed of two bars pivotally secured one to the table frame and the other to the table-leaf, each such bar having to its free end aloop through which the other bar is passed, both such loops forming guides for holding the bars on a relative parallel position during extension and contraction of the support; such loops also serving to form shoulders to each other to prevent the entire disconnection of the bars or the extension of such leafsupport beyond the desired limit.
The second part of my invention consists in a leaf-spring secured against one of the bars and engaging the notched end of the other bar when such supporting-brace is extended to its limit, for holding and preventing from swinging the tableleaf in either direction, all as more fully described, and specifically claimed.
In the accompanying drawings, Figure 1 represents the end elevation of the device holding the tableleaf on its elevated position; Fig. 2, a similar view of the device, with the tableleaf released and folded against the end of the table, and Fig. 3 a section on line a; m in Fig. 1.
Corresponding letters in the several figures of the drawings designate like parts.
A denotes a flat bar, pivoted by a suitable hinge-bracket, a, to the frame of the table, and Bis another similar bar pivoted by a suitable hinge-bracket, b, to the table-leaf. The bar A has secured to its extremity a loop, 0, through which the bar Bis passed, and the bar B has secured to its extremity a loop, (I, through which the bar A is passed in a man ner that the loop of each bar forms a rigid guide for the other bar, which loops, inter locking, will prevent such bars A. and B from disengagement, and will form stops or shoulders to each other, limiting the extension of such bars to the desired length. A leaf-spring, G, is secured by riveting against bar 13, the vibratable end of which spring 0 engages with a notch, e, filed into the end of bar A, when such bars A and B are extended to their limit, and will lock them on their extended position.
With raising the table-leaf to a horizontal position, so as to form a continuation of the table proper, the bars A and B will be extended by sliding by each other until theloops c and (I will butt against each other, and will allow no farther movement, when the spring 0 will jump into the notch e of bar A, and will thus lock the support, forming a rigid brace for such table-leaf, as shown in Fig. 1.
For folding the table-leaf again, to hang to the end of the table, the spring 0 only needs depressing with the finger, when it will occupy a position between the bars A and B, which now can slide past each other until they occupy a position sideby side, as shown in Fig. 2-.
A great advantage of this table-leaf support is that 'it cannot be extended beyond the desired length required for forming a brace for holding the table-leaf on a horizontal position, and therefore the hinges by which such tableleaf is connected to the table proper cannot be strained or broken.
hat I claim is- 1. The combination, with a table and a hinged leaf thereof, of an arm secured to the table-frame and provided at one end with a loop, a second arm pivoted to the leaf and provided with a loop, the arms arranged to slide each in the loop of the other, and a suitable locking device for such parts, as set forth.
2. A table-leaf support consisting of bars A and 13, each provided with a loop, 0 and d, forming guides for such bars, and of a suitable locking device ior holding such bars in their extended position, substantially as described, to operate as specified.
3. A table-leaf support consisting of bars A. and B, each provided with a loop, a and d, forming guides for such bars, and of leaf-sp ring 0, secured to bar B, and engaging with a notch or shoulder of bar A, all substantially as desubstantially as described, to operate as speci-' scribed, to operate as specified. fied.
4. A table-leaf support consisting of bar A, In testimony whereof I aftlx my signature pivotally secured to the table-frame, and pro in presence of two witnesses.
