. ADOLPHUS BADER, OF NElV YORK, N. Y.

Y EXTENSION-MELE,

To all whom 'it may concern:

Be it knownthat I, ADoLPHUs BADER, of the city, county, and State of New York, have invented a new and useful Extension- Table; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 represents a vertical longitudinal section of my table, when not extended, the line m, w, Fig. 2, indicating the plane of section. Fig. 2, is an inverted plan of the same. Fig. 3, is a vertical longitudinal section of my table, showing one of the extensions drawn out entirely, and the other extended half way.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in arranging a number of additional plates on arms which slide under the table top, said arms being made of such a shape and form that when l they are drawn out half way the plates which are supported by the same, are brought to form a continuous plane with the stationary top, thereby doubling the area of the table, and that when said arms are wholly drawn out, the plates which rest on them may be unfolded and brought in the same plane with the stationary top so that the area of the table is incr'eased three-:told or nearly so; and the arms are provided with springs and guide pins which move in suitable grooves and which serve to guide the armsand keep them in their proper places during the operation of drawing them in and out.

To enable others skilled in the art to fully understand and construct my invention, I will proceed to describe it.

The top A, of the table is placed on the frame B, and it is kept in the proper place by means ot' guide pins a, a, which lit into sockets in the central cross braces C, on which the top rests. The frame B, is strengthened by two longitudinal braces D, D, which serve as guides for the arms E, on which the additional plates F, and G, F', and G', rest. These. arms slide in notches b, in the frame, and they are guided by means of pins c, which fit into grooves (l, in the sides of the braces D, and fiat springs e, are attached to these braces in such a position that they keep the inner end of these arms constantlyY depressed. The arms are provided with notches f, which fit over projections g, at the under side of the cross brace C when the arms are drawn out half way, and hooks g", are attached to the inner ends of the arms which titover projections lz., at the inside of the frame B, when the same are drawn out entirely.

The plates F, F', are rigidly attached to the arms E, and the plates G, G', are hinged to the same in such a manner that they fold over them, as represented in Fig. l, and on one side of Fig. 3, or that they may be unfolded and brought in the same plane with the first plates F, as represented on the right hand side of Fig. 3. Additional legs H, are

hinged to the plates F, F', so that whenv these plates are wholly drawn out they drop down by their own gravity, and that they form a proper support at the ends of the table in an extended state, and to prevent these legs from being displaced by accident, folding stops I, are hinged to the under side ot the plates F, F', which fit into recesses h', and which turn down and form stops behind the legs, as soon as the legs are dropped.

The width of the arms E, is increasing toward their inner ends, so that the additional plates G, G', are brought up to the same level with the table top A, when the arms are drawn out half way, as represented on the left hand side of Fig. 3, and so that the plates F, F', are brought up to the same level with the stationary top A, when these arms are drawn out altogether, as represented on the right hand side of Fig. 3.

In order to extend this t-able, the top A, is raised a little and the additional plates are drawn out. If drawn out half way, the notches f, in the inner ends of the arms E, t over projections g, at the under side of the cross brace C, and the plates G, G', are now in the same level with the stationary top A. By this operation, the area of the table is doubled, or nearly so, as a plate. 'of nearly one half the size of the stationary top A, is added to the same on two sides.

If the arms are drawn out entirely, the plates F, F', are brought to a level with the top A, and the hooks g', tit over the projections L, which are attached to the inner side of the frame B. As soon as the arms are drawn out to the proper distance the legs H, drop down and support the plates F, F', and if the plates G, G', are now unfolded the area of the table is rendered nearly three times as large as its original area. In order to push in the additional plates, the legs H, are turned up, the plates Gr, Gr, are folded over the plates F, F, and the arms E, are pushed in. In this motion they are guided by the pins o, and by the notches, d. After they are pushed in halfway it is necessary to depress the inner ends of the arms a little, by raising the plates F, F', so that the notches j', clear the projections g, and at the same time the tabletop A, must be raised s'uciently to allow the plates Gr, G, to pass under its edge.

Having thus described iny invention,what I claim as new and desire to secure by Let ters Patent, is-

l, The arrangement of additional plates F, G, on arlns E, of such a shape and forni that by drawing out the arins the plates are brought to a level with the top of the table, substantially as described.

2. And I also claim, confining these arms at the proper places by means of the notches f, and the hooks g', and to guide the same by means of pins c, and notches el, substantially as specified.

AnoLr BADER.
