EXTENSION TABLE.

Applicationflled July 24, 1924, Serial No. 727,877. Renewed November 26,1927.

This invention relates to extension tables, and particularly to that class of table wherein the extension is effected by the addition of extra leaves.

It is an object of the invention to produce a table of the above class which is simple in structure and easy of manipulation.

It is a further object of the invention to produce an extension table which has anextension leaf or leaves permanently attached thereto and of such construction and arrangement as to be compactly folded and stowed beneath thetable top when not in use, and readily accessible and movable into place when extension is desired.

Another object of the invention is to utilize space beneath the table top'for the stowage of table extension means, which heretofore had been vacant or waste.

A still further object of the invention is to produce a table of the above class wherein the extension means is preferably permanently but slidingly secured to the table by an elevating device comprising swingingly arranged track-like guides adapted to first raise the extension means or leaf and to thereafter serve as guide tracks along which the leaf or leaves may be slid for placement with respect to the table top. 7 r

:0 A further object of the invention is to so arrange the above mentioned guide tracks that they may be locked in elevated position 7 to thereby enable freedom of the hands for the purpose of adjusting the extension means to osition.

ther objects of the invention will be further pointed out in the specification and the claims hereinafter given.

Of the drawings:

Figure 1 represents a top plan view of an extension table in its normal or unextended condition.

Figure 2 a view similar to Figure 1 but showing the two parts of the table top separated preparatory to introducing the extension means.

Figure 3 a view similar to Figure 1 showing the extension means in position for use.

Figure 4 is a section on an enlarged scale taken on the line 4-4 Figure 2.

Figure 5 is a view similar to Figure 4 showing the extension means about to be slid and unfolded into place.

Figure 6 is a section on the line 66 Figure 4.

Like characters represent like parts throughout the several figures of the drawings.

Referring to the drawings:

The drawings herewith illustrate their vention as applied to a well-known form of extension table, but it will be understood that it might be applied to other forms and that changes might be made in it without departing from its spirit and scope.

As the invention pertains to the top portion of the table it has not been deemed nec-. essary to illustrate the base or stand which however may be of any usual or suitable size and shape.

The usual post or pedestal 10,. in the present instance has a frame member 11 suitably secured thereto which slidingly supports the two halves of the top, 12 and 13, by means of the stationary guide members lt and 15 secured to the member 11; and the coacting guide members 16 and 17 movable with and in fact secured to the top halves 12 and 13 respectively.

The members 1 1 and 15 have suitable so tongues fast therewith which enter grooves of the members 16 and 17 as usual in tables of this type. 7 i

The space formed between the tops 12 and 13, and the member 11; by the members 14, 15, 16 and 17 very conveniently affords storagespace for one or more extension leaves 18, onl one of which is shown, hinged midway 0 its length as at 19 for the urpose of folding and storing in the sai space as. shown in Figure 4 of the drawings. l

The member 11 is herein shown as grooved as at 20 to receive screw eyes or similar devices 21 which serve as pivots for the guide tracks 22 to which the portion 18 of 95 the extension leaf 18 is slidingly connected by screw eyes or similar devices 23.

Preferably each extension leaf will have two such guide tracks but for convenience only one leaf and one pair of tracks is shown lou herein.

The said guide tracks 22 have a portion 24 angularly arranged with respect to the main body thereof, and a portion 25 bent at approximately right angles to said porum tion 24.

The portion 25 is adapted to extend through a hole 26- of the member 11 and has an extension 27 pivoted thereto by means of a rule joint, each pair ofextensions 27 1m being connected at their free ends by a rod 28.

When the table is in use and the extension leaf stowed as shown in Figure 4, the track extension members 27 will be swung upwardly till the rod 28 is engaged by the spring lock 29.

\Vhen the extension leaf is to be withdrawn for use, the table tops 12 and 13 will be separated as shown in Figure 2, the portions 27 Will be disengaged from the springs 29 and aligned with the portions whereupon upward pressure on the rod 28 will cause the tracks 22 to swing on their pivots into the position shown in Figure 5, at which. time the rod 28 will have engaged the lock springs 30.

The hands of the operator being free, the leaf 18 will be drawn up the incline of the tracks 2:2 till the eyes 23 meet the now l-vel portions 2% and the forward edge of the leaf portion 18 will be aligned with the corresponding edges of the top parts 12 and The leaf portion 18 will now be separated from the portion 18 and swung on the hinge 19 till it occupies the position shown in Figure 3 where it will be aided in its support by the extending plates as and 3d of the top parts 12 and 13 respectively, and the usual dowel pins and holes as shown.

The above described structure'is a simple one, but it will he understood that it is not the intention to limit the invention to the precise structure and arrangement shown, as it will be understood that changes might be made therein Without departing from the spirit and scope of the invention.

Having described the invention I claim:

1. An extension table provided with means to house an extension leaf; a two-part hinged leaf arranged to be housed in said means; means to elevate said two-part leaf from its housed position, said last means co iprising pivotally fixed guide tracks for said leaf and embracing said guide tracks; and

fast with said leaf whereby said leaf be slidingly guided along said tr: eks.

eyes may essence 2. An extension table provided with means to house an extension leaf; an exten sion leaf arranged to be housed in said means; a pivotally fixed slide along which said leaf is adapted to he moved; means to slidingly means to elevate the free end of said slide means prior to positioning said leaf; and means including said'last means whereby said slide may be locked against movement.

3. An extension table providedwith means to house an extension leaf; an extension leaf arranged to be housed by said means; an elevating slide means pivotally fixed to said table and along which said leaf is arranged to be moved in two planes; means to ClOVflLC the free end of said slide means prior to moving said leaf thereon; means to slidingly connect said leaf to said slide means including said elevating means; and means to lock said slide means against movement.

4:. An extension table provided with means to house an extension leaf; an extension leaf arranged to be housed by said means; a pair of tracks pivotally arranged with respect to said table; means to slid-,
