EDWIN JEFFERY, OF JERSEY CITY, NEW JERSEY.

impact/WENT IN SEWING ACB-EINE TABLES.

Specification forming part of Letters Patent N0. hldb, dated August 19, 1873; application filed July 2, 1873. l

.To all lwhom it may concer-n:

Be it known that I, EDWIN A. JEFFERY, of Jersey City, in the county of Hudson and State of N ew Jersey, have invented a new and useful Improvement in Combined Sewin g-Machine Tables and Covers, of which the following is a specification: Y

This invention relates to sewing-machine tables which are extended by the arrangement of the cover at the end or side of the same 5 and its object is to provide an improved fastening device for attaching such covers in an easy and efficient manner 5 and it consists in a pendulous bracket provided with a suitable catch or key, attached to the tabletop, in combination with hollow slotted eyes attached to the cover, said bracket and catch engaging with, said slotted .eyes to hold the cover in y position.

Figure 1 of the accompanying drawings is a side elevation of the cover of the machine and the mechanism for attaching` it to the table, a portion only of the latter being shown.

Fig. 2 is a front elevation of the cover, showing the slotted eyes thereto attached. Fig. 3 is an elevation of the end of the table, the lower portion of the frame being broken away, showing the pendulous bracket in full and in dotted lines, and the mode of attaching the cover by the same to the table to form an extension or receptacle, as required. Figs. e and 5 are fragmentary views, showing the hollow slotted eyes in section, and part of the pendulous bracketfand the mode of connecting one to the other to hold the cover in position.

As shown in the drawings, A is the table of the machine, and B the cover attached to theend of the same, the top being on a level therewith. 0n the under side of the table,

between the legs It and the edge of theend, a hanger or bearing, d, Figs. l and 3, is secured. In this bearing the bar or axis c of the bracket C is supported, and is capable of oscillating freely therein. On the outer end of the axis or bar e is a cross -head or key, l, Figs. 3, 4, and 5, arranged at right angles to the pendent portion of the bracket C. Arranged centrally on one side of the cover are two eyes, G G', in a vertical line with each other, as seen in Figs. l and 2. These eyes project a short distance from the side of the cover, as seen in Fig. '1, and are provided with slots a a in their faces, as seen in Fig. 2, their interior being hollow, as shown in Figs. 4 and 5, to'receive and retain the cross-head l.

To attach the cover to the end of the table the bracket is first raised to a horizontal position parallel with the under side of the table,

as shown by the full lines in Fig. 3. In this position the crosshead lis vertical, coinciding with the slots u u in the eyes G G when the cover is placed in a position on a plane with the top of the table, as in Fig. 1. The bracket is held in this position while the cover is placed at the end of the table, the molding at its top resting upon the molding on the edge of the table, and pressed forward till the crosshead l enters the slot in the eye G, as in Fig. 4. The bracket is then allowed to fall to a vertical position by its gravity, as in Fig. 1, and its lower end, which is bent outwardly, is sprung into the slot in the lower eye G. The cross-head Z, which had previously entered the eye G, has assumed, by the falling of the bracket, a position at right angles to the direction of the slot n, as seen in Fig. 5, by which the cover is securely locked in place, and can be detached only by disengaging the lower part of the bracket from the lower eye, and raising it to a horizontal position, an operation which can only be accomplished by design, and not by any strain bearing upon the cover. y

It will be seen that the lower part of the bracket is retained in place in the slot of the lower eye, not only by friction, but by the lateral pressure of the cover crowding against it, -and by the weight of the pendulous bracket itself, which always hangs in a vertical position, and hence the more strain upon the cover the more firm isits connection with the bracket.

The longitudinal extent of the bearing d c e, Fig. 1, is sufcient to form a strong support for the cover against either direct downward strain in the direction of arrow 1, or an oblique strain in the direction of arrow 2, the bracket acting as a brace against the latter.

The cover, it will be seen, is provided with two eyes, G G', so that itis capable of being attached to the table in an inverted position, to form a receptacle for work, &c., with the same facility as when used in an upright position to extend the table.

. Brackets may be arranged at the side of the table also, so that the cover may be attached at the side, if desired.

Ihave shown the slotted eyes as projecting from the side of the cover, and the cross-head l on the end of the bar e on avertical line with the end of the table, but the eyes may be recessed into the cover, and the cross-head project beyond the end of the table, if preferred.

The pendulous bracket is represented in the drawings as being composed of strong wire; but it may be formed of cast metal, of an ornamental design, or of other suitable material.

To detach the cover from lthe table, the lower end of the bracket is irst sprung out of the slot in the lower eye G, and the bracket then raised to ahorizontal position, as shown by the full lines in Fig. 3 and in Fig. 4, when Witnesses:
