UNITED STATES PATENT @EETcE GEORGE LAUTER AND JACOB KAUTZ, OF VINCENNES, INDIANA.

IMPROVED EXTENSION-TABLE.

Specification forming part 4of Letters Patent No. 57,927, dated September 11, 1866.

To all'whom fit may concern:

Be 1t known that we, GEORGE LAUTER and JACOB 'KAUTL of Vincennes, in the county of Knox and State of Indiana, have invented .'ings, making a pax-t of this specification, in

which- Y l Figure lis an elevation of one side of the table. Fig. 2 is a transverse section through the table, taken in the vertical plane indicated by red line x. Fig. 3 is a top view of the table when it is fully extended.

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

rlhe nature ot' our invention consists in connectin g together the two parts of an extensible table by means of folding and sliding rails, having sectional supporting-legs applied to them in such manner as to afford intermediate supports for the table, Whether extended or not, said extensible and sliding rails being so constructed as to admit of a lateral as well as longitudinalEextension or enlargement of the table, as will be hereinafter explained.

To enable others skilled in the art to understand our invention, we will describe its construction and operation.

In the accompanying drawings, A A represent the two halves of a rectangular table. Each half of the table consists of a ixed top, a, which projects beyond the ends of the side strips, b b, a distance which is equal to the width of the sectional intermediate supporting-legs, so that when the two halves A are'brought closely togetherthe sectional legs B will fit snugly and neatly between the ends ot' said side pieces, b, as shown in Fig. 1. Each portion A of the table is provided with two solid legs, O O, which are rigidly secured to .the outer corners, as shown in the drawings.

D D are narrow transverse strips, which are secured to the bottom edges and near the i11- ner ends of the strips b b; and cc are longitudinal strips, which are secured to the inside surfaces and near the bottom edges ot said strips b b.

The strips D D and c 0, together with the side strips, b b, and top, boards, a a, form receptacles for the sliding portions of the extensible frame, and also serve as supports for the side rails, d d, thereof. rlhese side rails have a longitudinal sliding movement in opening or closing the table, and they are secured rigidly to their respective half-legs B at their inner ends, and to transverse pieces e e at their outer ends. These pieces e o are hinged together centrally, and provided with studs f fon their lower edges, near their outer ends, which studs enter grooves that are made on the upper surfaces of the strips D D when the table is extended. The studs ff, workin g in the grooves in strips D D, serve as stops, and also as pivots. As stops they prevent the sliding sections from being detached from the table-halves A, and as pivots they allow the inner ends of therails dd to be spread out laterally, as shown in Fig. 3. This lateral extension ot' the rails el Z is eeeted by having the cross-strips c e hinged together centrally and the inner ends of the pieces l) b beveled outward.

The grooves in strips D D, in which studs f f slide, are curved, as represented in Fig. 3 in dotted lines, for the purpose of allowing the inner ends of the strips or rails d d to approach each other when they are drawn out to their fullest extent, and when the outer ends of these strips are spread apart.

vWhen the studs f f are in the straight por tions of the grooves the strips d d and ce will be at right angles to each other, and the legs B B will be in line with the legs O O; but when the table is extended and the studs are brought within the oblique termini of their grooves the sectional or half-legs B B will be muchfarther apart laterally than the legs C C, as clearly shown in Fig. 3.

To the inner ends of the sliding rails d el short stri )s d d are hin Oed which are again hinged to longer strips d2 cl2. Thehinges connecting strips or rails d d and cl2 dz are hinged together by means of joints, which allow these strips to fold inward when the table-sections A A are brought together.

It will be seen from the above description that we connect the two halves of the table together by means of a frame which is not only longitudinally extensible, but which is so constructed and applied to said halves thatit can be extended laterally, and thus increase the Width,as well asle1'1gth,ot` the table; andwhile of an extensible table7 substantially as detbis is the ease7 the said frame affords a firm scribed.

support for the movable sections of the table- 2. Connecting the outer ends of the sliding top, which are used for filling up the space rail-sections d cl together by means of jointed between the ends of the tixed top boards7 a a, cross-pieces e e, substantially as described.

when the table is extended.

Having thus described our invention, what ER' we claim as new, and desire to secure by Letters Patent, is- Witnesses:
