2 Claims.

This invention relates to new and useful improvements in tables.

The invention has for an object the construction of a table which is characterized by a table top, a frame supporting the table top and having recesses in the sides, or in the ends, into which a table top leaf or leaves may repose in a position parallel to and adjacently beneath the table top, and a novel arrangement for supporting the table top leaf or leaves in a manner so that they may be extended and elevated to have their top faces in the same plane with the top face of the table top, and for supporting a table drawer at the free edge of the extendable leaf for the convenience of the housewife and to cover the operating mechanism.

More specifically the invention contemplates characterizing the supporting means for each table top leaf by pairs of parallel slides slidably mounted on the frame of the table beneath the table top leaf, and pairs of parallel members adjacent said slides and attached to and supporting the table top leaf, and a novel cooperative means connecting the adjacent slides and members together for making the members movable forwards and upwards relative to the slides and latchable in the said raised position.

Still further the invention contemplates a novel means for holding the table top leaf in vari- 30 ous elevated positions on the members so that it is possible to obtain an eXtra fine adjustment to make the top face of the table top leaf absolutely flush with the top face of the table top.

For further comprehension ofthe invention,

35 and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 16 is an end elevational view of Fig. 15.

The table, according to this invention, includes a table top I0 which is supported on a frame II having recesses I2 into which supplementary table top leaves I3 may repose. The frame II is supported by several legs I4 which rest upon the floor. The frame II comprises end wall boards IIa, side wall boards IIb, and transverse boards II mounted between the side boards IIb. The table top I0 is secured to the frame II by several metallic plates I5 attached to the end walls IIa and attached to the bottom face of the table top I0. A novel means is provided for supporting each of the leaves I3 and this means is identical for both of the leaves, and consequently but one of the means will be described in this specification.

A pair of parallel slides I8 are slidably mounted on the boards IIc of the frame II and are arranged to slide parallel with and beneath the table top leaf I3. A pair of parallel members I9 are disposed adjacent the slides I8 and are attached to and support the leaf I3. A cooperative means is provided connecting adjacent slides I8 and the members I9 for making the members I 9 movable forwards and upwards relative to the slides I8, and to be latchable in raised positions, as hereinafter more fully described. A novel means is also provided for holding the table top leaf I3 in various elevated positions on the members I9 as hereinafter more fully described.

Each slide I8 is formed from a relatively long strip of material bent so as to have an outwardly projecting central portion I8 and edge flanges I8b. These edge flanges are slidably engaged in a track which is mounted upon the board I IC. The track 20 is formed with slots 2l through which fastening elements 22 pass. These fastening elements comprise screws and engage into the material of the board IIC. The slots 2| permit the tracks 20 to be adjusted forwards or rearwards as may be required for the proper operation of the table top leaf. The forward end of the track 20 is provided with a stop 23, in the nature of a lug stamped from the material of the track and extended inwards. The slide I8 is provided within an inwardly projecting pin 24 (see Fig. 6) which is engageable against the lug 23 to limit forward motion of the slide I8 in relation to the supporting track 20.

Each of the said members I9 is formed from a strip of material .bent to have a vertical wall I9a disposed adjacent the outwardly projecting central portion I8a of the slide. The member I9 also has atop wall I9b which is secured in a novel way with the leaf I3. Speciiically, the -vwall I9b is formed with several downwardly extending tubular socket portions I9C which are formed with internal threads. A hollow tubular 'member 25 threadedly engages each tubular socket I9". The tubular member 25 has a closed end 25a through which a fastening element, such as the screw 26 passes and said .screw 2l6 threa-dedly engages in the leaff I3. The arrangement is such that each tubular member 25 vis turnably supported by the screw 26. The bottom end of each tubular member 25 is formed with diametrically opposite slots 21 for receiving a screw d-river, or other turning tool by which the tubular member 25 may be turned. When the tubular members 25 are t-urned the leaf I3 will be ravis-ed and supported alt various elevated positions from the top walls I9b of the members I 9.

The top walls I9b of the members I9 `continue into angular shaped track side portions 19d. A -drawer 28 for the table is supported between the track portions ISd of the said members I9. This drawer may be moved outwards and inwards relative :to the leaf I3, and may move along with the leaf as -a unit. The tracks I9d have forwardly extending end portions I9dd for facilitating the proper support of the drawer 218. This drawer covers the slide mechanism and is furnished for the convenience of the housewife. `The drawers 23 may be extended relative to the leaves I3. This is possible when the leaves are in their extended positions, as` well as when they are in their retracted positions.

'Ihe cooperative means connecting the adjacent slides I8 and the members I9 for making the members |19 movable forwards and upwards relative to the slides, and latchable in raised positions, include headed studs 3U projecting inwards from the slides `I8 .and extending through slots 3I and 32 formed in thevertical wall portions I'9a of the mem'bers I9. The slots 31| are disposed towards Athe front `of the slots `32. Each slot 3l has a rear horizontal portion 3 Ia which connects with la front upwardly extending portion 31h. Each slot 32 has a bottom rearwardly extending portion 32a which connects with an upwardly forwardly extending portion 321.

In Fig. 15 .another embodiment of the invention has been disclosed distinguishing from the prior f-orm merely in the fact thalt the table top leaves are arranged upon the ends of fthe ltable rather than upon the sides. More sp'eoiiic-ally, the table shown in Fig. 15 includes la table top I0' supported by ya frame ;II which is provided with recesses I2' at .the ends thereof. Table top leaves I3 .are disposable within the recesses I2 and are extendable therefrom. These leaves are supported yby mechanism identical to that previously described. Each leaf I3 is also provided with a drawer 28 identical to the arrangement previously described. In other respects this form of the invention is similar to the previous form and simil-ar pants may ibe identified by like reference numerals.

The operation of the table constructed according to this inventionisas follows:

In Fig. 4 the table top leaf I3 is shown in its inoperative position disposed within the recess I2 and located immediately below the table top I0. To extend the leaf I3 it is merely necessary that it be manually gripped and first pull-ed outwards to the po-sition indicated in IFlg. 6. When the leaf I'3 is pulled outwards the slides I8 merely move outward on the tracks 2U to positions in which the stoppins 24 of the slides I8 strike the stop lugs 23 of the tracks 2U. Then theleaf I3 is pulled forwards and upwards so that the gslots 3I and 32 .travel vforwards on the studs 30. This motion is continued until the forward studs 3U engage into the bott-om horizontal projections 3la o-f the front slots 3l :and the rear studs :30 4are disposed at the rear ends of the horizontal portions l312a of the rear slots 312. Then the leaf I3 is pushed slightly rearwards so that the rear studs engage into the front `ends `of the slots 32. This locks the =leaf I3 in a raised position. The parts are now :as illustrated in Fig.' 7. Then the leaf I3 is moved rearwards so that [the -slides I8 move .slightly inwards on Ithe tracks "2U until a position is reached in which the rear edge yof the leaf I3 intimately engages the front edge of the table top I0. The parts are now in the position illustrated in Eig. 8 and the leaf is fully extended.

YWhile we have illustrated and described .the preferred embodiments of our invention, it is to be understood that we do not limit ourselves to the precise constructions herein disclosed and the right is reserved to all changes :and modifications comin'g within .the scope of the invention as `defined in the appended claims.

Having thus ide-scribed our invention, what we claim as new, and desire to secure by United Sta-tes Letters Patent is: v
