EXTENSEON- TABLE,

Specification of Letters Patent.

Patented Nov. 13, 1906.

Appilcation Malaw -1221906 Serial No 313,982.

Be it known that. 1, CHARLES ll. (lnldilitl, a citizen of the United States, residing at llicksville, in the county of Dr-tianco and State of Ohio, have invented crrt'ain now and useful improvements in Extension-1ntales, of which the following is a specification.

This invention relates to the art of turniture, and more particulati to extt tlsiotl-tahles ot the type which embody in tht ir general organization one or a phnzttit ot' extension-loavos carried by the table struct ure and adapted to be brought into position as a part t of the table-top for extension purposes or withdrawn to a housed position b neath the main table-top sections at the will o" the oporator. To this end the invention has specially in view certain novel and practical improveinents which sim'plil'y extension-tables of this chamcter and at the sztliic time a re intended to secure a positive and reliable operation in throwing the extension teat or leaves in and out of position through the movement ot the main table-sections.

A further object of the invention is to providc simple and practical means for automatically etlooting tho t'olding of side rail-soctions for the extonsion-leavos through the movement of sttch leaves by their raising and lowering mechanism. This l'eaturo provides a construction wherein the individual extension-loaves as llush with the main table-top also serve to automaticaltv swing into place sido-rliil sections which aline with the fixed side-rail members ol the main table-sections.

Another object ol' the invention is to associate Willi the leaf raising and havering mechanism a simple and ell'cctivo l'orm ol' latching device which servos to lock the main tablosoctions closed and also to lock such sections against l'urt her relat ivo movement after each extension-twat is thrown up into operative position, thereby compelling the release of the latching device belore it is possible to start the movonu-nt necessary for bringing into use one of tho extensiou-loavos.

\Vith those and other objects in View, which will more *adily appear as the nature ol the invention is better understood, the same consists in tho novel construction, combination, and arrangement ol' parts hereinaftcr more l'ully described illustrated, and claimed.

The essential l'caturcs oi the invention involved in carrying out the objects above indithey are thrown into positioit cat ed are necessarily susceptible to structural change without departing from the scope of the invention; but a preferred embodiment t thoreot is shown in the accompanying drawings, in which-- Figure 1 is a perspective view, partially in section. of an extension-table embodying the improved extension-loaf mechanism contemplated by the present invention and showing the extension-leaves in normal retracted positions housed beneath the main tablet0p. i Fig. 2 is a bottom plan view of the table showing the parts in the positions they 00- cupy when the extension-leaves are lifted into place llnsh with. the top of the main table section. Fig. 3 is a detail sectional view on. the line 3 3 of Fig. 2. Fig. 4 is a detail viewillustrat ing the movement of the throw: links for swinging the side-rail sections'outward and inward. Figs. 5, 6, 7, and 8 area series ol similar longitudinal sectional Views illustrating the series of ditl'erent positions assumed by the several parts of the mechanism in the operation of positioning and withdrawing one or a plurality of extensionleaves.

Like references designate corresponding parts in the several figures of the drawings.

in (arrying out the present invention no features of construction of an ordinary extension-table, as the improvements claimed herein relate exclusively to an arrangement of one or a plurality of extension-leaves within the tabletop and associated with improved leaf raising and lowering mechanism, which provides means for automatically raising the individual leaves into active position between the tops of the main table-sections, .and also i or automatically retracting or lowering the leaves to a housed posit ion beneath the main table-top, simply through the opening and closing movement of said tablesec tions. With this understanding of the general outline of the invention, therois shown in the drawings, for illustrative purposes, an extoiisiou-tablo. which comprises in its gen eral organization the oppositoly-arranged and matching main table- sections 1 and 2, having the usual top portions 3, adapted to meet in closely-abutting relation as indicated at 4 in Fig. l ot" the drawtngs,whcn the table is closed to its normal size without the interposition ol' extension-leaves. The said main table-sections l and 2 are also pro- 5 vidod at the side edges therool' with the usual material change is required in the generalv ICC The rosin.

The links 11 l'or CzLCll extension-leaf swing or rock in a horizontal direction, so that the leaf 8, supported upon the upper end of the links, Will likewise swing or move in a horizontal direction and at the some time will always maintain its position in a horizontal plane. Furtherinore by reason of supporting the leaf 8 upon the upper ends of swinging carrierlinlrs, said links as theyswing in one direction to whet only he termed their folded position curry the extension-leaf 8 below the pl itne ol' the main table-top, while the swing-- ing or straightening out of the levers in the other direction serves to carry and lift the extension-leaf to its elevated position in trlinement and llush with the main table-top portions. v

- fixed abutment 28 and serving sociate with the i'eatures described a latching tween its two shoulders for disengaging purl poses, as will presently appear. In connecl tion with these features of construction it is to he observed that pair of the operatingbars more employed, respectively, at opposite sides of the longitudinal center of the table,whereb v one bar is associated with each pair of carrier-liiilcs. I

For practical purposes itis preferable to asdevice essentially comprising a fixed catchbar section 223. provided with a plurality of spaced catch-notches 3'1 and a latch-lei er 25, The said latcli-levr L5 is pivotally-supported interiiiediate its ends on a vertical pivot-pin, so to permit of the horizontal rocking of said lever, and at its outer'end portion the latter is provided with a spring membernormally pressing under tension. against a j to noi'iiiallv move the engaging point 2%) at the opposite end of the lever against. the fixed catch-bar l 23 and into engagement with the notches 2. when said pin reaches the plane of said notches. f The outer end portion of the latch-lever I 225 has connected therewith flexible or other 5 equivalent release-strip 30, operating as a, handle for moving the outer end of the latchl lever in a direction for releasing the point 22$), and thereby permitting free movement of the table-sect ion 9, either inward or outward l Another feature. of the invention resides in l associating with the folding side-rail sections 9 simple and improved means for moving; such sections inward and out ard. he said means consists simply in the employment of a single throw-link Ill, associated with each siderail section 9 and pivotally connected at its outer end. as at 32. to the inner side of sttCltSOCiiOll and at its inner end pivotally supported, as at 33, upon the outer side 01 one o the fixed supporting iiiei-ub rs or bars, 7. The link of each tolding side-rail section 9 sets obliquely and is of greater length than the distance between such sections when swung out and the adjacent supporting meniber or bar 7. Q1100 when the extension-leaf end of the throw-links are moved toward or from the fixed supporting members or bars 7, with the result of automatically swinging the folding side-rail sections on their liingesl,

Referring to the general operation ol the table, reference need only be made to the. group of Figs. 5 to inclusive, oi the drawii'igs. in the first place, assume that the table is closed and the extension-leaves are lowered and housed in the positions shown in Fig. 5. To open the table and bring illU'tktension-leaves into use, the latch-lever T first released and then the movable table-, section 2 drawn outward. This movement; carries the advance press-shoulder 16 of the l i l i i l i l l l l l 8 is shifted in a horizontal direction the outer t i l l l l l i I l i leaf, bringing the latter operating-bar 19 against the tappet-pin 15 of the link rock-arm 14. with the resultof throwmg the links 11 upward, thereby carrying the first ext.eiision-leai $1 into its elevated posh t'iou. This is plainly shown in Fig. 6,0 the drawings. and if only one leaf be used the mo 'able table-section 2 is closed back onto the said first leaf 3 after the parts have reached the position showiiin Fig. 6. With the parts in said position (shown in Fig. 6) the movabletable-section 2 cannot be opened, bringing the shoulders 17 past the tappet-pin 15 on account of the point 1?!) of the latch-- lever becoming locked in a notch 24. beloi'e such position can be reached. llence when it is desired to also bring the second leat' into play, the latching device is held released during the opening inevenieiit, so that by a continued movement of the movable table-settion the release cain it will pre s down on the tree end of the bar it), serving to disengage fthe shoulder It and ptl'lillt the said shoulder to pass on into engagement with the next succeeding tappet-pin 15, thereby repeating the sameraising operation for the. second into the position shown in Fig. 7.

To return the leaves to their retraeted positions, the movable table-section 2 is first carried out to the position shown in Fig. 7 and then started on its return movement. This movement Carries the return-slioulder 17 into engagement with the successive tappet-pins t5, thus causing the successive leaves to automaticallywithdraw one after the other without any interruption in the closing up of the talile-seetions 2.

Front the foregoing it is thought that the construction, o 'ieriition, and many advantages oi the hereiii-described invention will be thoroughly understood without further description;-but at this point it should be observed that the foregoing description, forsake of clearness, has been based on the assumption thatthe table-seetionl is a fixed section, while the section '2 is a movable section; but it will ol course be understood that in practic at construction and use of the table both of the sections 1 and 2 are necessarily movable, and the. table is intended to be filled by the extension-1eaves in equal proportions in each section. I

it maybe tiurther observed that, it desired, leverage-assisting springs 3 may be ul ilized to bring the extension leaves into position without drawing the section or sections entirelv out till a notch 24 of the cateh bar is reached. in using these springs the same are connected at their opposite ends respectively to a swinging carrier-link below its pivotal point and an adjacent part of the table-lraiiuwvork.
