EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent N0. 780,927, dated January 24, 1905.

Application filed April 27, 1904.. semi No. 205,114.

T alt whom it may concern: I Be it known that we, EUGENE T. WESTER- FIELD and RAN OLPH F. WESTERFIELD, cit'i, Zens of the United States, and residents of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Extension Tables, of whlch the following s a specification.

c The invention relates to improvements in extension-tables; .and it consists in the novel features and combinations of parts hereinafter described, and particularly pointed out in the claims. Y

The object of the invention is to provide a very efficient, simple, and convenient extension-table and one of a construction adapted to conceal withinitself extension-leaves (preferably folded) and upon the extending ofthe The invention will befully understood from v the detailed description hereinafter presented, reference being had to the accompanying drawings, in which Figure 1 is a top elevation, partly broken away, of an extension-tableconstructed in accordance with and embodying the invention;

the table being shown in its extended condition with the extension-leaves in position, one pair ofsaid extension-leaves being illustrated by dotted lines. Fig. 2 is a longitudinal-section-of same on the dotted line 2 2 of Fig. 1, both pairs of the extension-leaves being shown in position.

Fig.3 is a like view of same, the table being shown in its contracted condition with the pairs of extension-leaves con cealed below the table-top. Fig. 4 is a bottom view of same. Fig. 5 isa longitudinal section corresponding with Fig. 2, but showing the table in a partly-contracted position to indicate the automatic action of the extension-leaves in disappearing below the tablebracket which cooperates with the extensionleaves; and Fig. 81s an enlarged sectional view on the dotted line 8 8 of Fig; 4 and illustrates the method of locking the ends of the table at the transverse rails of same whensaid ends are in their contracted condition shown in Figs. 3 and 4. v

In the drawings, 10-11 designate the main table-tOpsections; 12 13, the legs therefor,

and 14 15 the usual transverse rails respectively connecting the legs 12 with each other and the legs 13 with each other and supporting said main top'sections 1O 11.

At the center of the table is provided a transverse rail 16, supported upon the upper end of a central leg 17 and upon the ends of the rail 16 are secured the longitudinal bars or rails 18 19, which correspond with each other and are provided upon their opposite edges with the dovetail guideways 20 21, receiving the correspondingly-grooved edges of the longitudinal rails 22 23, respectively connected with the main end sections of the table, said rails 22 23 being in the'present instancelfastened at their ends to the end rails .15 1 1 andinterposed bars 24., extending transversely at the ends of the table between the top sections 10 11 and said rails 22 23.

The table so far as hereinbefore specifically described may be considered as of ordinary construction in respect of the main end parts 25 26, mounted upon legs and having rails 18 19, secured to the cross-bar or central transverse rail 16, serve as means for guiding the rails 22 23 during the movement of the ends 25 26 of the table toward and from each other.

Our invention resides more'particularlyin the pairs of hinged extension-leaves 27 28 and I The facing edges of the top sections 10 11 the means for automatically elevating said leaves during the separation of the table end sections 26 and for causing their automatic lowering and final disappearance during the contraction of the table or the shoving of said end sections toward each other.

The pairs of extension-leaves 27 28 correspond with each other, and each pair comprises the leaves 29 30, hinged together at 31, Figs. 5 and 6, so that the leaf 30 may be folded inwardly over upon the leaf 29, as shown in Figs. 3 and 5. The leaves 29 have secured upon their under sides the cleats 32 and hinged pins. 33, Fig. 6.

The rails 22, connected with the end section 26, have secured upon their outer edges the brackets 34, which have their downwardly and outwardly longitudinally inclined surfaces 35 and preferably the upper horizontal surfaces 36, and these brackets 34 receive upon them when the table is extended and during the outward and inward movements of the end section 26 the cleats 32 of the extension-leaves 28, said cleats 32 when the table is in its extended condition resting upon the horizontal surfaces 36 of said brackets, as shown in Fig. 2, and said cleats being adapted to ride down the said inclined surfaces 35 when the end section 26 is pushed toward the end section 25,

as shown in Fig. 5. The brackets 34 are applied to the outer edges of the outer rails 22, and they cooperate with the extensionleaves 28. Upon the inner edges of the rails 23 are applied brackets 37, corresponding with the brackets 34 and having the downwardly and outwardly inclined surfaces 38 and preferably the horizontal surfaces 39. The brackets 37 cooperate with the pair of hinged leaves 27, and the leaves 27 correspond withthe leaves 28, but are not connected therewith. The hinged pins 33, carried by the leaves 29 of the pairs of leaves 27 28, extend downwardly into free apertures 40, provided in the stationary rails 18 19, and the said pins hold the pairs of leaves 27 28 in proper relation to each other and also allow the tilting of said pairs of leaves in the manner shown in Fig. 5 during the extension of the table and also during its contraction or when the end sections 25 26 are pushed toward each other, whereby, for illustration, when the said end sections are being pushed toward each other and the inclined surfaces 35 38 of the brackets 34 37 pass under the cleats 32 the outer ends of the then-folded leaves 27 28 may of their own weight tilt downwardly, as shown in Fig. 5, and pass below the top sections 10 11 during the continued motion of the latter toward each other, the said inclined surfaces 35 38 finally passing inwardly from below said cleats 32 and leaving the folded extension-leaves 27 28 resting upon the stationary rails 18 19 and movable rails 22 23, which is their position shown in Figs. 3 and 4.

are provided with lips 41, which when the table is extended and the extension-leaves 27 28 are in their upper position may be utilized to support the outer edges of the leaves 30, the pairs of leaves 27 28 being in their folded position (shown in Fig. 5) when the table is first extended and the leaves 30 thereof then being turned outwardly into the position in which they are shown in Figs. 1 and 2, with the outer edges of said leaves 30 resting upon said lips 41, as shown, the entire table-top then being on one horizontal plane and at such time the leaves 29 being supported horizontally by reason of the fact that the cleats 32 then rest upon the upper horizontal portions of the brackets 34 37.

Those portions of the table at one side of the stationary transverse bar 16 constitute substantially a duplicate of those portions of the table at the opposite side of said bar.

The end sections 25 26 are each locked to the middle stationary portion of the table when the table is in its initial contracted condition by spring-catches 42 43, respectively secured to the ends of the rails 19 18 and respectively adapted to engage the transverse rails 15 14, as shown in Figs. 4 and 8. The catches 42 43 may be disengaged from the rails 15 14 when it is desired to extend the table either by the direct application of the finger thereto or by means of a spring-pin 44, such as shown in Fig. 8. It will be necessary to hold the catches 42 43 out of engagement with the 'rails 15 14 until the table-sections have started on their outward movement, and then said catches may be released, and in practical use it will be found to be convenient to first release one catch and extend its end of the table and then release the other catch and extend that end of the table.

The initial contracted condition of the table is represented in Figs. 3 and 4, in which it will be seen that the pairs of leaves 27 28 are in their folded position below the table-top and resting upon the rails 18 19 22 23, that the brackets 34 for the leaves 28 have passed inwardly beyond the cleats 32 of said leaves, and that the brackets 37 for the pair of leaves 27 have passed inwardly beyond the cleats 32 for said leaves 27. In considering the operation of the table it may be assumed that it is desired to pull the end section 26 outwardly, so as to utilize the leaves 28, and under such condition the attendant will release the catch 42 and pull the section 26 in a direction outwardly from the table-section 25. The movement in an outward direction of the section 26 will result in the rails 22 being drawn outwardly and in the brackets 34 being carried ITO under the cleats 32 of the folded leaves 28, v

the inclined surfaces 35 of said brackets first riding under the inner ends of said cleats 32 and gradually tilting said ends and the inner edges of said leaves upwardly, and the motion of the section 26 being continued the said surfaces 35 of said brackets will ride along under said cleats 32 and finally elevate the leaves 28 to their upper position, the horizontal surfaces 36 then being under and maintaining said cleats and leaves, after which the leaf30 will be folded over outwardly from the leaf 29 and its outer edges caused to rest upon the lips 41, connected with the top section 11, as shown in Fig. 2. During the outward movement of the section 26 the brackets 34 tilt the folded leaves 28 upwardly more and more as the top section 11 passes outwardly from over said leaves. The table-section may then be extended outwardly, and as it is moved outwardly it will through the rails 23 cause the brackets 37 to ride below the cleats 32 of the folded leaves 27 and effect the elevation of said leaves, after which the leaf of the pair of leaves 27 will be unfolded or turned outwardly and at its outer edges caused to rest upon the lips 41 of the top section 10,

the table then being in its fully-extendedposition. (Shown in Figs. 1 and 2.) When it is desired to contract the table and conceal the extension-leaves below thetop of same, the attendants will turn the leaves 30 over upon the leaves 29 and then push the end sections 25 26 of the table toward. each other. During the contraction of the table the brackets 34 will ride under the cleats 32 of the then-folded leaves 28 and the brackets 37 will ride under the cleats 32 of the thenfolded leaves 27, and as the inclined surfaces of said brackets reach and ride under said cleats the folded leaves will tilt downwardly at their outer edges in the manner represented at Fig. 5, and finally the said brackets will leave the cleats entirely and allow the folded leaves to settle down upon the rails 18 19 22 23, as shown in Fig. 3. During the extension of the table the inner edges of the leaves 27 28 first gradually elevate, and during the contraction of said table the outer edges of said leaves are first acted upon to tilt downwardly. The elevation-and depression of the leaves 27 28 are accomplished automatically merelyby the pulling apartof the table-sections 25 26. and the shoving together of said sections.

The brackets 34 37 are in the nature of wedges in that their inclined surfaces during the extension of the table move the folded leaves upwardly and during the contraction of the table effect the downward movement of the inner edges of the leaves 27 28 to the stationary portion of the table,and thereby per- 33 freely descend, so that the leaves may assume their lower horizontal position. The brackets 34 37 are so disposed with respect to the cleats 32 that when the table is to be extended the top sections 10 11 will separate to some little extent from each other before said brackets contact with said cleats and thatduring the final shortening movement of the table parts said brackets will leave or pass inwardly beyond said cleats in advance of the coming together of the facing edges of said top sections l0 11. The brackets 34 being at the outer sides of the sliding rails 22 may be moved without danger of their contacting with the stationary transverse bar 16; but since the brackets 37 are. secured to the inner edges of the inner rails' 23 and have to slide by the said bar 16 said bar is grooved or boxed, as at 45, to form passage-ways for said brackets 37.
