Application filed October 25, 1916. Serial No. 127,604.

To aZZ 'whom t may concern.'

Be it known that I, BENJAMIN Zinnen, a citizen of the United States, resident of Minneapolis, county of Hennepin. State of Minnesota, have invented certain new and useful Improvements in Tables, of which the following is a specification.

The object of my invention is to provide a table which can be easily and quickly increased or decreased in the size or area of its top to adapt it for a library or living room table or for a dining or breakfast room table.

)ther objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this' specification,

Figure 1 is a plan sectional view of my .improved table in its collapsed or folded condition,

Fig. 2 is a transverse sectional view of the same,

F ig. 3 is a plan sectional view, showing the table expanded,

Fig. 4 is a sectional view showing the leaf raised to the level of the table top and near the end of its upward movement,

Fig. 5 is a transverse sectional view of the table closed,

Fig. 6 is a transverse sectional view of the table in its open position,

Fig. 7 is a view corresponding to Fig. 4, taken on a section line at right angles substantially to the section line of Fig. 6, with the leaf unfolded between the sides of the table top.

In the drawing, 2 represents the legs of the table of any ordinary or preferred construction. 3 represents side bars and 4 end bars between the connecting or side bars. 5 represents rails. having groove and tongue connections with a-stationary rail 5', disposed preferably between the rails 5 and mounted on the tops of the legs. The bars 5 are connected respectively to table top sections 6 and 7 and are movable back and forth on the rails 5" to open and close the table top. This manner of mounting the top sections on the sliding rails is of ordinary construction in tables and I make no claim to the same herein.

Between these sliding bars at right angles substantially thereto I provide rails 8 in parallel relation with one another upon opposite sides of the middle portion of the table: These rails are secured to the bars 9 which extend horizontally between the up- 'per portions of the legs and between the sliding bars 5, and are suitably secured to rails 5. The inner faces of the rails 8 are provided with cam grooves 10 having horizontal end portions 11 and 12 and between the rails I provide a leaf composed preferably of sections 13 and 14, having their abutting ends hinged together by means of invisible hinges 15, which I do not illustrate in detail, as they are ordinary stock hinges.

A cross bar 16 is provided on the section 14 near one end, having gudgeons 17 to slide in the grooves 10. The lower ends of the grooves are near the lower edges of the rails 8 and the upper ends of the grooves are near the upper edges of these rails and when the leaf sections are folded, they will drop down between the rails 8 and the sliding bars of the table top and allow the bars to be moved toward one another to close or contract the table, the top sections having the usual dowel pins 18 and sockets 19 to register when the sections of the top are moved against one another.

The ends of the lower leaf section 14 have` grooves 19 therein to receive the pins 18 when the leaf is raised `to a level withthe table top, and the upper leaf section 13'has notches 20 therein to receive the dowel pins at the opposite end of the top sections andV thereby the leaf will be securely locked in its raised position. As shown plainly in Fig. 7, the upper ends of the grooves 10 are substantially horizontal and the gudgeons seated therein will-be firmly supported and the upper surface of the leaf, when raised and unfolded, will be securely supported on a level with the table top, even under the weight of heavy articles which may be placed on the table. I also prefer to provide a cam block 21 with which the end of the lower leaf section contacts when the table is opened and the leaf is raised. The substantially horizontal upper portions of the grooves 10 insure a stable support for the folding leaves and eliminate any possibility of their sliding downward accidenn tallyin the cam before the user desires toV close the table.

In using the table, the top sections are pulled apart to expose the space between them. The operator will'then grasp the free end of the upper leaf. section 13 and raise it away from the other section, at the same time exerting sufficient pressure on the 1. lower section to cause 1t to slide upwardly in the` grooves until it 1s on a level ,with thctable top and the end of the lower leaf section in alinement with the corresponding ends of the top section. The upper leaf section .isl then dropped down upon the dowel pins and the table -is readyfor use. As the sections ride up inthe cam.; grooves, the end of the leaf will strike the block '21 and be guided thereby upwardly tothe space between the' sliding sections f-of the to llo fold the table, the upper-leaf section may be raised or tilted overupon the lower` section and the two moved-endwise, with the gudgeonssliding in the grooves andthe end-of the lower section following a lguide 2l until the ksections are below the level, cf

the table top, when theftop sections may beA moved toward one another to closethe gap between tliemand conceal the leaf. f

In various ways the-details Aofconstruction herein shown l.and described `may be modiiedfand stillbe within the scopeof invention.y

I claim as my invention:
