It will be understood thatiwhile both the h n he p r ofl-th lak fie" 8r to I has been drawn.fromgunderithe adjacent -95 1" permits the passage of the leaves 19 and 20, respectively, in a plane subsequently occupied by said outer edges of said leaves 18 and 19. j

As seen best in Fig. 5 of the drawings, the leaves 19 and 20 are partially supported in their fully extended condition by the swing- V ing legs 85. The legs 35 are supported in framed relation by the cross braces 36 and 37, the latter of which is'hinged to a cleat 38 secured permanently to the under side of the leaf 20. Normally, the legs 35 are disposed in the raised position shown in Fig. 4 of the drawings, by means of gravity latches 39, which engage the brace 36 when the said legs are lifted to the folded position. When the legs 35 are lifted to their folded position, the leaves 20 and parts connected therewith are pushed back under the leaves 19, to accomplish which the outer or free edges of the leaves 19 are lifted to permit the inner edges of theleaves 20 to pass thereunder. The guide grooves 40 in the frames 22 are in clined so that when the outer end of the leaves '20 pass below the outer ends of the leaves 19, the outer ends of the said leaves 19 are lowered to the operating level thereof. In this position, the leaves 20 are pressed back to the position assumed in Fig. 3 of'the drawings and shown best at the right hand side thereof. In the position just above described, the latch 21 engages the leaf 20 to hold the leaves 19 and 20 thereafter in operative relation.

As shown best in Fig. 6 of the drawings,

the sliding frames 22 have clove-tailed or,

T-shaped grooves 41 wherein roll frame guides for the rollers 41. The rollers 41 are secured toeach of the supports and at the opposite endsthereof. These rollers are ar ranged in pairs and mutually engage the grooves 40 of the adjacent member of the frames 22. While the rollers 41 are herein shown as operatively engaging T-shaped grooves 40, it will be understood that other forms of grooves and sliding members .disposed therein may be employed in lieu of the rollers and grooves disclosed. I

It will be understood that the leaves 18 and 19 are'hinged or pivotally connected with their supporting frames at the inner.

edge thereof, sufficient movement being accorded-to the outer edges of each of the mentioned leaves to permit the lift of the outer edges for the passage thereunder of the fixed edge of the adjacent leaf, as, for instance, the hinge 42, which holds the leaf 19 to its support at'the inner end of the said leaf, permits the lift of the outer edge of the leaf table and serves to hold the meeting edges of the said leaves 18 in mutual alinement. The inner edges of the leaves 18 are structurally secured to the cross brace 17 byscrews 44. The movement of the leaves 18 are'guided by the blocks 45, which are rigidlysecured to said leaves adjacent the opposite side of the table, as shown in Fig. 6 of the drawings. Theblocks 45 normally rest in openings46 1n the cross brace 17. 'When the leaves 18 rock on the-joint formed'on the tongue 43,: .the blocks 45' serve to maintain the aline- I 02am- 1.
