TABLE Application filed May 19, 1930. Serial No. 458,565.

The invention relates to tables, and particularly to tables of the extension leaf type, and has for its object to provide a table of this character in which the extension leaves are positioned beneath the table top in parallel relation thereto when in. retracted inoperative position.

. A further object is to provide a table of this character provided with a table top having depending side flanges within which the extension leaves are adapted to be nested when in retracted position, said top being tiltable relative to the table frame to permit withdrawal of the leaves to operative extended position. 1 c

A further object is to provide. a table of this character having extension leaves adapted to be locked in retracted position and means for automatically projecting said leaves to operative extended position upon release of the means locking said leaves in retracted position.

A further object is to provide a table of this character having its top flexibly connected to the table frame and controlled by guide means permitting only tilting of the top relative to the frame and preventing simultaneous equal upward movement of all points ofithe top relative to the frame.

A. further object is to provide a table of this character having means carried the top for locking the extension leaves in retracted. position, means for automatically projecting the leaves to operative extended 35 position upon predetermined shifting of the table top to release the locking means, and

means for guiding the shifting of the top in the predetermined manner. i

With the above and other objects in view,

40 the invention resides in the combination and arrangement of parts as hereinafter set forth,

shown in the drawings,described and claimed,

it being understood that changes in the pre cise embodiment of the invention may be 45 made within the scope of what is claimed without departing from the spirit of the invention. 1

Referring to the drawings, which illustrate the preferred embodiment of the invention, the numeral 10 designates a table frame comprising end rails 11, side rails12 and legs 13. The upper portion of the end ofeach side rail 12 is cut away at 14, and mounted centrally 7 in said cut-away portions 14 and extending transversely of the table framebetween the opposite side rails are guide members 15. Guide members 15 are preferably T-shaped the stem of the T being supported by said side rails and 30 he upper surfaces of the guide members being substantially level with the top of the side and end rails of the table frame. Mounted on the table frame is a table top 16, preferably of conventional sheet metal construction, and having flanges 17 depending from' its perimeter in the conventional manner; said flanges receiving a supporting frame18 therein which includes a central longitudinal cleat 19. At each end of the table top a headed pin 20 depends vertically from the cleat 19 and passes through an aperture 21 formed in the guide member 15 therebeneath, Figure 9, said aperture being of a size to'permit the pin to have a slight lateral movement as well as free longitudinal movement therein. Springs 22 are carried by cleat 19 and are connected to the end rails 11 adjacent the lower edges thereof. The springs 22 and pins 20 form the sole connection between the table top and table frame;

V the pins serving to correctly position the table 7 extending through the cut-away portions 14:

of the side rails of the frame. Supporting frames 24, carried by the under sides of guide members 15 and projecting laterally therefrom, support the bars 23 in operativehorizontal position. Mounted on the outer ends of bars 23 at the opposite sides of the table frame are extension leaves 25, said leaves being of a length less than the inner dimensions of the supporting frame 18 and of a width less than the distance between the cleat 19 and the supporting frame-whereby the extension leaves may be nested within the depending flanges of the table top and so held in retracted position. Springs 26 extend between the innerends of the bars 23' and the opposite side of the table frame, said springs acting to force said bars and extension leaves outwardly of the table top into extended position. Stops 27 are carried by the bars 23to limit the outward movement of the bars and extension leaves relative to the table top whereby said leaves will not be projected outwardly beyond operative extended position by springs 26. Atthe center of the inner side of each end rail and near the lower edge thereof is mounted a V-shaped guide block 28, having its lower point out oif, and above block 28 a pin 29 is secured to cleat 19 in vertically depending relation, said pin 29 having at its lower end a perpendicularly bent hook portion 30 disposable beneath said block.

'When the table is'inits normal position with the extension leaves 25 in retracted posi- 7 with the leaves. .Up-ward tilting movement tion, the table top telescopes and rests upon said leaves, and the dependingflanges 17 of the top, into which said leaves nest, lock the leaves in retracted position against the action of the springs 26; the springs 22 drawing the of one side of'the tabletop against the action of springs 22 releases'one of the extension leaves from its telescoped interlocked relation with the top; and said leaf is then automatically projected outwardly of the frame- 7 by its cooperating springs 26. The outward movement of said leaf is limited .by the stops 27which stop said leaf at its extended position at a point clear of and adjacent the outer edge of the table top, so that upon release of the top to its normal horizontal position the top and extension leaf are in substantially contacting relation at their proximate edges and form a continuous'table top. Tilting connection between the frame. 1

The top is effectively prevented from excessive tilting relative to the frame by the headedepins 20 whose head engages the guides 15 to limit said tilting movement; the apertures '21 in guides 15 through which said pins pass being of a size to permit the slight tilting of the pin therein. The combination of the V- shaped guide blocks 28 and the pins 29 serves to guide the tilting movement of the top and to prevent simultaneous equal upward movement of all parts of the top relative o the frame. Upon tilting of the top the hook portion 30 of pin 29 is swung clear of the bottomofthe block 28 and engages the upwardly outwardly inclined sides of said block whose inclination permits continued tilting ofthe top as is required to'release the extension leaf from its nested position beneath the top. Upon direct upward application of force to the table top in a manner tending to simultaneously equally move all parts of the top relative to the table frame, the hook portion 30 of pin 29 engages the under side of the block and prevents movement of the top relative to the frame. Thus it is made possible to centrallygrasp the table top to carry the table without causing tilting or other movement of the top relative to the frame, and it is not necessary for the frame itself to be grasped as would otherwise be necessa-ry in a table of this construction'having no fixed table top and table The invention having been set forth, what is claimed as new and useful is:

In combination, a table frame, a table top shiftable relative to said frame, a V- shaped block carried by said frame, and a pin depending from said top and having a perpendicularly bent portion disposed beneath said block and adapted to engage one of the inclined sides of said block to tilt said top upon movement of the top relative to the frame. V

8. In combination, a table frame, a table top shiftable relative to said frame, an extension leaf slidable relative to said frame and normally held in retracted position beneath said top, and guide means controlling the movement of the top relative to said frame to tilt said top toward one of its ends to release said leaf.

11. In combination, a table frame, a table top vertically shiftable relative to said frame, a member fixedly carried by said frame at the center thereof, and a hook depending from said top and normally engaging said memberto prevent shifting of said top, said hook being shiftable to avoid said member to permit selective tilting of either end of said top relative to said frame.

In testimony whereof I afiix my signature.
