EXTENSION TABLE.

Application filed January 20, 1926.

This invention relates to improvements in extensible tables and has for its main object the provision of an extensible table having leaves hidden underneath a main table top that is adapted to rise above the upper surface of the leaves when the table is operated for extension and to form a cor; tinuous surface with the said leaves when the table is extended to the required width.

Another object of this invention is to provide means wnereby the table top will rise out of the plane of the leaves when the table is operated to return to a contracted or narrower width.

Other objects and novel features of my invention will be more fully described as the specification proceeds.

In the drawings, forming a part of this specification Figure 1 is a plan view of such a table with my improvements applied thereto;

Figure 2 is a sectional view on line 2-2 of Figure 1;

Figure 3 is a sectional view of the slide mechanism, taken on line 3-3 of Figure 1;

Figure 1 is a view similar to Figure 2 showing the table top raised above the leaves;

Figure 5 is a similar view to Figure 4.- showing the table fully extended and the table top forming a continuoussurface with the leaves; 4

Figure 6 is a fragmental sectional view showing the table top raised above the top of the leaves with the table ready to be contracted to its narrowest width;

Figure 7 is a detail view of the guiding means for maintaining the table top at the proper height when the leaves are being returned to their hidden position; and

Figure 8 is an end view showing a modification in which an auxiliary table top raising means is employed.

Referring to the drawings in detail, 10 indicates a table supporting frame having legs 11 suitably attached thereto.

Fixed to said frame 10 and centrally located thereon is a slide bar 12 having "l" shaped grooves 13 and 14: cut therein substantially through its entire length. Vertically disposed guide slots 15 and 16 are cut on opposite sides of the slide bar 12 and guide therein bars or rods 17 and 18 fixed to cross bars or rods 19, 20. Said rods 19, 20 are fixed to and support a table top 21 SeriaI No. 82,431.

overlying leaves 22 and 23 fixed to slide members 2 1 and 25 on opposite sides and cooperating with the fixed slide bar 12.

Revolvably mounted on the bar 12 is a gear 26 engaging racks 27, 28, fixed to the slide members 2%, 25 and extending in opposite directions of the center of the said gear 26.

To operate the table for extension, all that is necessary is to draw either the slide 24 or slide 25 in the direction as indicated by the arrows in Figures 1, 2 and 4. If we operate slide 24 the rack 27 will revolve thegear 26 and transmit motion to the rack 28 fixed to the slide 25. As the slide 24 is drawn forwardly a roller 30 mounted on the supporting bar 18 and normally resting in a recess 31 (Figs. 2 and 1) will ride up on a cam surface 32 forming one side of the recess in the slide member 24, thereby raising the table top above the leaves 22 and 23, permitting the drawing out of the leaves from their hidden position without being scratched. As the drawing out process proceeds, the roller 30 will encounter a recess 33, into which it will drop, carrying with it the rod 18 and the table top 21 to a level flush with the leaves 22 and It will be understood that the same action takes place simultaneously at the opposite side of the gear. As the slide 25 moves outwardly a roller 3% mounted on the rod 17 normally resting in a recess 35 will ride up on an incline or cam surface 36, aiding to raise the table top 21, and then drop into the recess 37, allowing the table top to become flush with the leaves 22 and 23, in the opened or extended position of the table. (Fig. 5.)

In order to close the table the leaves 22 and 23 are drawn still further outwardly and the rollers 30 and 3 1 will ride up on inclines or cam surfaces 10, 41 of the recesses 33, 37, thus raising the table top to a higher level than that of the leaves 22, 23 and pern'iitting the said leaves to be returned to their normal concealed posit-ion. During this operation the rollers 30 and 34 will encounter members 12 shown for the sake of convenience abutting stops 43 secured in slots 4:4: and 45 in the slide members 2% and 25. Further outward movement of the slides 24 and 25 will cause the rollers 30 and 34 toride up on to a platform 48- of the member 42 until they reach stop blocks 49 supported on a guide Wall 50 integral with the memher 18. The table is now ready to be closed and the slides 2d and are caused to move inwardly while the guide members 12 support the rollers and 34 and prevent them and the table top 21 from dropping into the recesses 33 and 37 on the return of the slides and the leaves 22 and 23 to theirclosed position. As the recesses 33 and 37 in the slides carrying the leaves have passed beyond the rollers, pins 51 in the slides return the guide members to their normal posit-ion and the rollers 30 and 3e are permitted to ride on ledges 52 of the slides 22 and 23 and finally drop back into the recesses or cut out portions 31 and re spectively, and the table is then again in contracted form. Guide disks 53 and rollers 54 at opposite ends of the slides 2 1 and 25 and at opposite ends and sides of the fixed central slide member 12 and in guiding the slides to and fro.

In Figure 8 I have shown a modified form of my invention in which I make use of an auxiliary roller mounted on a bracket 61 fixed to the underside of the table top 21, said roller cooperating with a member 62 fixed to either one or both of the slides 24 and 25. This member 62 has depressions 63 and 64: equivalent to and in line with recesses 31, 33, 35 and 37, to allow for the up and down movement of the table top 21 and take the pressure off from the rollers 30 and 34L.

From the above, it will be seen that I have provided an extensible table having a table top overlying a plurality of leaves fixed to slides the said table top being adapted to be raised so that the leaves may be drawn out and the table top to be lowered to an even level with the said leaves when the leaves are fully extended, and to again raise the table top and maintain same in raised position until the leaves are returned to their normal hidden position and means for accomplishing same.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. An extensible table having a supporting frame, a slide fixed to the supporting frame, a movable slide on either side of the fixed slide, leaves fixed to said movable slides, a table top overlying said leaves, a ledge on each of the movable slides having a recess therein, a plurality of rods fixed to the table top, a roller on each of the rods adapted to cooperate with the said recess in each of the ledges to permit the table top to be lowered into the same plane with the leaves when they are fully extended, a

cam surface on each of the said ledges adapted to raise the table top above the height of the leaves to permit the leaves to be retracted, and a member Within the slides cooperating with each of the rollers to maintain the table top in raised position while the leaves are being retracted.

2. An extensible table having ing frame, a slide fixed to the supporting frame, a movable slide on either side of the fixed slide, leaves fixed to saidl movable slides, a table top overlying said leaves, a ledge on each of the movable slides having a recess therein, a plurality of rods fixed to the table top, a roller on each of the rods adapted to cooperate with the said recess in each of the ledges to permit the table top to be lowered into the same plane with the leaves when they are fully extended, a stop within each of the movable slide members, a guide member in each of the movable slides, said guide members being operably mounted in both the fixed and movable slides, and a block on said guide members cooperating with the said stop and adapted to be operated by the rollers to limit the out ward movement of the leaves.

3. An extensible table having a supporting frame, a slide fixed to the supporting frame, a movable slide on either side of the fixed slide, leaves fixed to said movable slides, a table top overlying said leaves, a ledge on each of the movable slides having a recess therein, a plurality of rods fixed to the table top, a roller on each of the rods adapted to cooperate with the said recess in each of the ledges to permit the table top to be lowered into the same plane with the leaves when they are fully extended, and a member mounted within the said slides adapted to maintain the table top in raised position while the leaves are being retracted.

l. An extensible table having a supporting frame, a slide fixed to the supporting frame, a movable slide on either side of the fixed slide, leaves fixed to said movable slides, a table top overlying said leaves, a ledge on each of the movable slides having a plurality of recesses therein, a plurality of rods fixed to the table top, a roller on each of the rods adapted to cooperate with the said recesses in each of the ledges to permit the table top to be first lifted above the leaves to allow for extension and then lowered into the same plane with the leaves when they are fully extended, and a member within the slides cooperating with the rollers to maintain the table top in raised position while the leaves are being retracted.
