tdtiit me FELIX-SOUWEINE. OF NEW YORK, N. Y..
Letters Patent No. 114,722, dated May 9, 1871.
IMPRQVEMENT IN EXTENS-ION TABLES.
The Schedule referred to in these Letters Patent and making part of thel lame.
To all 4whom 'it may concern Be itknown that I, FELIX SoUwErNE, of the city,
county, and State `of New York, have invented a new and useful Improvementin Extension Table; and I do herebydeclare thatthe following is a full, clear, and exactdescription thereof', which will enable those skilled in the art tomakc and use the same, reference being had tothe accompanying drawing forming part of this specification.
This invention relatesl to a `new and improved method of constructing extension tables, whereby many objections to the old method are obviated; and
The'invention consists in extending the table by a screw placed beneath the top of the table, as hereinafter'more fully described.
Figure 1 is a vertical longitudinal section of the table through the line xx of tig; 2, showing the screw and-the manuel' ot' its operation.
Figure-2 is a view of the reverse side of the table.
Figure 3 is a cross-.section through theline y y of fig.' 2, showing the form of the slides upon the sides of the table.
Similar letters'of reference indicate corresponding parts.
A represents the top of the table.
B is the screw, one end of which is fixed permanently to the table by a plate, C, and two collars, al d, s o that it can have no longitudinal motion, but is allowed to revolve freely..
E is a crank-key, which is fitted to the end of the screw, by which itis revolved.
F is a transverse bar, to which the nut of the screw is attached. y
' This bar is attached to the ends of the slides g.
The other ends of these slides are attached to the movable end ofthe table, which-end is marked H.
Irepresents rabbeted strips wnich t the slides g, and which are screwed permanently to the other or stationary end of the table. These pieces (g and I) form the ways upon whichthe table is extended.
J is the nut ofthe screw.
K is a tube in which the screw moves, which tn'be is attached to the bar F at l, and to the extension end ofthe table at m, as seen in the drawing.
As the screw is revolved the movable part of the table H is extended, the opposite end being supposed to be stationary; but either end (or both at the same time) may be moved by the screw, if desirable.
When the table is extended, as seen in the drawing,the leaves L (one or more) are pnt in, when the same can be screwed up tightly, making a close joint at all times'.
Instead of the.screw, arranged as described, I propose to use sometimes a. sectional tube, the sections being arranged to slide together like the tube of a telescope.
The ends of the tube would be attached to the ends of the table.
Such a tube is shown at N in the drawing.
Being properly supported the etiect would be equivalentto the screw.
The screw and a sectional tube forming telescopic joints may be used in combination with each otherl for the purpose of extending the table, if desired. Having described my invention,
What I claimas new, and desire tosecure by -Letied.
F. SOUWEINE.
