WIRE-STITCHING-MACHINE TABLE.-

' T0 all'whom it may concern: dicatedin Figs. 2 and 3, is of angular form Be it known that I, Josrrrr PAGLIARUL, awith its apex presented upwardly; and the citizen of the United States, residing in outer ends of said extensions 12 carry at Chicago, county of Cook, and State of Illitheir downwardly projecting corners a set nois, have invented certain new andluseful of-longitudinally extending outwardly fac- 60 Improvements in Wire-Stitching-Machine ing bosses 13.

The table as a whole wire stitching machine tables, and particuis supported at the apex'of each end of'said 65 larly refers to the type of table which may extensions 12 by meansof a hinge, one part be converted from the fiat to the saddle type, of which 17 is attached to the under side of as desired. the leaf 15, and the other vertical limb 18 The salient objects of the invention are, of the hinge is adjustably secured to a verto provide a table of the class described tically extending lug 19 projecting down- 70 which may be used either for flat or saddle wardly from the end of each of the memstitching; to provide a table of the class dehere 12.

Thebraces ross-Section of these extenslonsl2 as I l- 23are quitefre'e to swing toward the apex'llo of the table support, but they are prevented from swinging outwardly by means of pins 26 driven into the ends of the bosses 13 at the right place to engage the vertical limbs of the braces 23 when the latter are in upright position, and said braces are main tained in upright position by means of a pair of coil tension springs 27 which extend across and are connected to the depending extensions 28 of said braces 23.

hen it is desired to use the table for saddle stitching, the braces 23 are lowered into the position shown in Fig. 3, this lowering being rendered somewhat easier by c0nstructing the lower ends 28 of the braces with an outwardly projecting bow so as to make room for the convenient application of the finger of the operator. It should be noted that the top of the table support is grooved out, as shown at 29, so as to accommodate the horizontal limbs of the braces 23 and-enable the leaves of the table to lie sub stantially fiat against the table-support. It should also be understood that the weight of the table leaves 14 and 15 is sufficient to overcome the springs 27 when the table is.

arranged for saddle stitching, as shown in Fig. 3, and consequently there is no danger of said springs 27 improperly restoring the table leaves into their horizontal position. This is easily comprehended when it is seen that the spring 27 is connected to a point comparatively close to the pivots 25, and the upper extensions of said braces 23 extend a considerable distance from the pivot and engage theunder side of the table leaves much nearer to the hinge axis than the center of gravity of the table leaves. If it is desired to re-convert the table from saddle stitching relation to plain or side stitching position, obviously, the only thing necessary to do is to place the fingers under the outer edges of the leaves 1% and 15 and swing the leaves upwardly into horizontal position, upon which the braces 23, under the influence of the springs 27, will return to their normal upright position and form the requisite support for the table leaves so as to maintain them in horizontal position.

In view of the above description, it is manifest that my construction requires for its manipulation no tools whatever, nor is any adjustment of the various parts required in order to convert the table from one to the other stitching position. The working parts of the table are also such as to be capable of being manufactured at very small expense, while at the same time the construction is neat, compact, substantial, and efiicient to attain the desired result.

It is manifest that some of the details of the parts may be modified considerably without departing from the spirit of the invention or sacrificing any of the benefits or advantages of the invention, and thus I do hinge connection ot wish to be limited by the above description, except as specified in the appended claims.

I cla1mand a table-leaf hinged to the upper portion of said support, and supported in position by said brace.

In a table of the class described, the combination of a relatively fixed support having an upper portion and a laterally ofiset lower extension, an upstanding brace horizontally pivoted to said lower extension of said support and adapted to swing to: ward said support, automatic means for urging said brace outwardly away from said support, a stop for arresting the outward movement of said brace, and a table leaf horizontally hinged to the upper portion of said support and supported in horizontal position by said brace.

3. In a table of the class described, the combination of a longitudinally extending, relatively fixed support provided with a at the top of each end thereof and provided with four lower corner extensions, a pair of braces each horizontally pivoted upon an axially alined pair of two of said corner extensions and i one side of and parallel to the axis of said hinge connections, said brace being provided with a horizontallyextending portion adapted to swing toward said hinges on said pivots and normally disposed vertically above said pivots, automatic means tending to urge said horizontal brace portions away from said hinges, a stop adapted to arrest movement of said brace and maintain said brace with its horizontal portion substantially vertically above the pivotal axis of said brace, and a pair of abutting leaf members hinged together and supported by said fixed hinge connections at their hinge axis and resting upon the horizontal 4.
