TO ALL WHOM IT MAY CONCERN:

Be it known that we, AUGUSTUS P. SHUTE and JOHN F. JACKSON, both of' Charlestown, in the county of Middlesex, and State of' Massachusetts, have invented an improved Extension-Table Slide; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of our invention consists in providing the sliding bars of an extension-table with narrow metallic strips, running parallel to each other and longitudinally with the bnrs,but inclined to each other in section, working in corresponding grooves, thus making a neat, strong, and cheap sliding connection for thebars.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and use. In the drawingsi Figure lis a perspective view, showing a set of these bars as they appear when drawn out.

Figure 2 is an elevation and part section, the elevation being represented as thou-gh cut ofi' on the line Y, iig. 3.

Figure 3 is anl end elevation of our slide. v

We construct our slide as follows We make, of any suitable wood, a number of bars A B C, and with a circular sa\v,'or with any other convenient tool, make the grooves E El parallel to each other in a longitudinal direction, as shown in figs. 1 and 2, but inclined to each otherin cross-section, as shown in fig. 3. The depth and width of these grooves may be varied to suit the reqirements of the onse. A short thin piece of metal, Dm', Hg. 2, is inserted into the grooves at one end of each bar, and made fiist by means of screws or'nails, so

that if two of the bars are put together, as shown by A and B, fig. 3, two of these inelined'metallic pieces DD.

would he attached to B, and wouldslide in the grooves E E ot' A. Each bar being provided with sets of these metallic pieces D D', &e., it will be seen that the bars slide upon each other until the metallic pieces strike eaen other, as shown by D D, fig. 2. '.lo prevent the bars from being slipped backwards by each other, pins K K v are inserted into the pieces A and B.

The number of bars would vary to suit the requirements of the table, a long table requiring many and a. shortvtable but few.

The'advantages that we 4claim forour invention are extreme simplicity, eheapness, and durability.

Having thus described our invention, we will'proceed to set forth our claim.

What we claim as our invention, and desire to secure by Letters Patent, is

The combination, as well as the arrangement, of the metallic slips D D DIl with the grooves E E and the bars` A B C, made substantially as described and for the purpose set forth.

i l AUGUSTUS P. SHUTE,

-JOHN FQ JACKSON.'
