EXTENSION TO FOR TABLES.

Application filed. July 21,

Another ob]ect is to provide a swinging extension leaf construction for tables whose tops are provided with depending aprons in which the extension leaves are so arranged that they may be quickly chambered beneath the top and withdrawn therefrom into an ex tended position without the necessity of providing special form of hinges to avoid the aprons when extending the same.

A further objectis to provide a foldable extension leaf construction for tables in which the inner edges of the extension leaves term a.- part of' the table aprons when the same are folded beneath the table top. I

A still further object is to provide an ex tension leaf construction for tables-provided with stationary tops and depending apronslnwhich the leaves are hingedly secured tocutaway portions of the aprons, whereby leaves of amaximum width may be employed.

The. above and other objects are attained by means of the construction described in the following, specification, reference being hadto thedrawings accompanying the same, in. which:-

Referringnow more particularly to-the drawings the table illustrated is a type known to the trade as a."library or living room table, consisting of a solid top 5, provided on its under face adjacent its edges with depending aprons 6, and supporting I legs 1 terminating 1n the usual support ng bases.

' Secured to oppositely disposed sides 8,

9 of the table top are extension leaves 10,

11, whose outer edges may be of any desired artistic form, and as these leaves are exactly sim lar and are operated in the samemanner only one will be described. for brevity of description. The inn-er edges 12 of the leaves as well as the edges 13. of the table top sides 8. 9. which registerwith each other when the leaves are extended. are in the form of suitable moldings, illustrated in this case as cyma recta moldings... althoughother artistic forms mayv be employed with equah facility.

- Leaf 10 is secured to the table top apron 6 by means of leaf hinges 14. 15, the said apron being cut away as at 16, to permit the leaf to swing beneath the top without the necessity of providing special hinges to pass around the aprons asis usual in constructions of this type.

Hinge leaf 18 together with its pintle is seated andsecured in a recess 19 formed in the bottom face 20 of the cut-away portion of apron 6, while leaf 21 is secured to the under face of cleats 22 rigidlyafiixed to the under face of the extension leaf, asclearly shown in the various views of the. drawing. The inner ends of the cleats are in the form of moldings corresponding to the upper molding of the apron 6, whose outer vertical face is formed of aplurality of cyma recta mouldings 23, 24, 25, arranged in stepped relation to each other as clearly shown in edge of the table top While the inner ends of the cleats will nest in the molding 24 of the apron.

In order to rigidly supportthe leaf in its extended position a slide 26 is employed one for each leaf, the same being mounted n grooved guide rails 27 secured to the un der face of the table top. and movable to an operative position through an opening 28 formed in the table apron. In the upper surface of the slide is formed an elongated groove 29 extending from the front end and opening at the rear, a spring operated metal rod 30 being disposed therein fonforcing the slide outwardly into convenient reach of an operator when it is desired to extend the leaves, and to maintain the leaf in engagement with the catch 31 secured to the under face of the slide adjacent its inner end when the leaf is folded beneath the top.

Metal rod 30 is chambered in the grooves 29 formed in both leaf supporting slides and supported above the groove bottoms by an eye 32 secured to the under face of the table top mid-way of its side edges 8. and 9. Mounted on this rod are a pair of coil-ed springs 33. 34:. one on each side of the eye, the free ends of the springs engaging circular washers 35, 36 loosely mounted on the rod. These washers normally engage the ends of the slides when the leaves are folded beneath the table top and serve to main-' .tain the catch 31 in positive engagement with its catch plate 38 secured to the under surface of the table leaf 10 adjacent its outer end. The end of catch plate that engages the catch 31 projects into a recess 40 formed in under surface of the leaf adjacent its outer end in order that the hooked end of the catch may readily engage with the plate, and to provide room for the movement of the catch when the leaves are to be released from an extended position, see Fig. 8. The secured end of the catch plate is convexed as at 4:1 and serves as a. wedge between the slide 26 and the leaf 10 when the same is extended to maintain the upper surface of the leaf level with the table top surface. and to prevent movement of the same when the table is in use. 1

The method of operating the table will be apparent from the following description.

Assuming it is desired to extend the table leaves, the leaf being chambered beneath the top as shown at the left in Fig. 6, the operator pushes the slide 26 inwardly a short distance in order to disengage the catch 31 from the plate 38 which will permit the leaf to swing downwardly, the spring 33 bearing against washer 35 forcing the slide outwardly into the dotted position shown in Fig. 6 to enable the operator to engage the recess 45 to pull the slide outwardly and beneath the leaf which has been swung into its extended position. Then the slide has been leaves in their extended or chambered posidrawn outwardly to the limit of its movement the upper surface at its outer end will contact with the wedge portion 41 of the catch plate, thus insuringv stability of the leaf in its extended position and preventing any rattling of the same when in use.

The method of chambering the leaf beneath the table top is as simple as the method of extending the same. The opera? tor first pushes the slide inwardly to the limit of its movement and against the action of the coiled spring 34: permitting the leaf to swing downwardly as shown in dotted lines in Fig. 5. The leaf is then swung upwardly under the top until the catch 31 is chambered in the recess 40 of the leaf,when the pressure against the slide is withdrawn the spring bearing against the washer 36 will force the slide outwardly and force the catch in positive locking engagement with the end of the catch plate 38 as clearly shown in Fig. 8 of the drawing.

By attaching the hinge leaf 21 to the cleats 22, which are of the same thickness as the thickness of the upper portion 23 of the apron, the use of a special form of hinge is avoided, the cleats raising the leaf so that its outer surface lies flush with the top surface of the table top.

As the attached edges of the foldable leaves completely fill the mutilated portions ofthe aprons when the leaves are folded beneath the table top, it will be apparent that the aprons will present an unbroken appearance, the vertical joints between the leaves and aprons being practically invisible to the eyes of an ordinary observer.

As the locking and unlocking of the tions are controlled directly by the slides it will be clear that an operator may conveniently extend or chamber the leaves without the necessity of reaching under the aprons or manipulating mechanisms.

What I claim is 1. An extension table embodying a stationary table top, a leaf movable with relation tovthe table top and having an edge adapted to register with the table top edge, a slide movably connected to the table top for 1 supporting the leaf in its extended position, a latch carried by the slide, a latch, plate secured to the under face of the leaf, and a spring mechanism carried by the table top and acting against the slide for forcing the latch into locking engagement with the latch plate, the latch adapted to be disconnected from the latch plate to release the leaf on a movement of the slide.

2. An extension table construction em bodying a stationary table top having a depending apron around the edge of the table top, a portion of the apron being mutilated, a leaf movable with relation to the table top and having an edge adapted to register with the table top edge hingedly secured to the apron at the mutilated portion, a slide secured to the table top and movable through an opening in the apron above the leaf for supporting the leaf in its extended position, a locking means secured to the slide and engaging the leaf to look the leaf in its folded position beneath the table top, the lock adapted to be operated to loclr or unlock the leaf on a movement, of the slide, the outer end of the leaf When folded closing the mutilated portion of the apron.

3. An extension table construction em bodying a stationary table top, an extension leaf movable With relation to the table top and having an edge adapted to register With the table top edge, a leaf supporting means slidably mounted underneath the table top for supporting the leaf when the same is extended, a locking means carried by the leaf and the leaf supporting means for locking the leaf in its folded position beneath the table top, said locking means adapted to be GEORGE W. KRICK.
