IMPROVEMENT IN SLIDES FOR EXTENSION TABLES.

Specification forming part of Letters Patent No. 122,278, dated December 26, 1871.

SPECIFICATION.

I, JAMES PLEUKIIARP, of the city of Columbus, county of Franklin, State of Ohio, have invented an Improved Slide for an Extension Table, of which the following is a specification:

Objects of the Invention.

The objects of this invention are to furnish a convenient slide for fastening together the two main parts of extension tables, at the same time leaving said parts free to be drawn a Certain distance asunder, and also furnishing a smooth solid support for extra leaves to be inserted when the table is thus extended.

Description of Drawing.

Figure 1 is a top View of the slide. Fig. 2 is a bottom view of the slide. Fig. 3 lis a view of one end of the slide, right side up. Fig. 4 is a View ofthe reverse end of slide, also right side up.

General Description.

A B C D are the sections of the slide, in number from three upward, according to the length of the table required, made of hard Wood one and one-quarter by one and one-half inches square, Or larger. a b c d c fare castings of iron or other metal, in the shape of'a letter L, as shown in the end views of the slide, viz., Figs. 3 and 4. They may be of any depth, according to the strength required. In the top view, Fig. 1, and end View, Fig. 3, the casting e is 'fastened by screws not visible to the section A, the casting b to the section B, and the casting c to the section C. In the bottom view, Fig. 2, and end View, Fig. 4,

the casting d is fastened tothe section B, the

casting e to the section C, the casting f to the section D. g g g and g g g are grooves in the sections, in which the tongues h h h and h h h of the castings slide, viz., the tongue of the casting a sliding in the groove of the section B, the

tongue of the casting b sliding in the groove of the section C, and in the same manner the tongue of each casting, both upon the top and bottom,

sliding in the groove of the adjacent section, thus binding them together laterally, at the same time allowing the sections free movement out and in longitudinally. j k 1. mn o are tongues or iianges upon the top of the L-castings, and sliding in grooves in the sides ofthe adjacent sections, the

tongue j sliding in a groove in the side of the section B, the tongue 7c sliding in a groove in the side of the section C, &c., &c., thus preventing any upward or downward movement of the sections. The tongues or iianges p g r s t n are each sunk in the section to which the casting, of which the tongue is a part, is fastened, and are merely to strengthen the fastening of the casting to its respective section. o o o, in Fig. 2, are screws inserted in the grooves g' g g', to prevent the sections sliding too far, and thus coming apart. a@ ww x are holes for screws, which fasten the slide to the under side of the immovable part of the table-top. a' and a: fasten `the section A to one end ofthe table, and a," x fasten the section D to the other end of the table. The slide is thus adj usted and ready for operation. TWO slides are required for each table.
