UNITED STATES PATENT OFFICE.

GARRET Q. DOLLIVER, OF PLAINFIELD, NEIV JERSEY.

EXTENSION-TABLE.

SPECIFICATION forming part of Letters PatentV No. 393,890, dated December 4, 1888.

Application filed November 7,1887. Serial No. 254,468. (No model.)

T0 all whom it may concern:

Beit known that I, GARRET Q. DoLLIvER, a

' citizen of the United States, residing at Plainfield, in the State of New Jersey, have invented certain new and useful Improvements in Extension-Tables; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to `provide an extension-table which will be more convenient, durable, and less expensive in construction as compared with those heretofore in use, and also to provide a receptacle in the table itself to receive the leaves when not required for use, thereby avoiding the necessity of providing a receptacle for the leaves independent of the table, and the liability of said leaves being lost or misplaced.

The invention consists in the improved eX- tension-table, and in the arrangements and combinations of parts thereof, substantially as will be hereinafter set forth, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in lwhich like letters of reference indicate corresponding parts in each of the several figures, Figure l, Sheet l, is a top view of said table extended, the intermediate leaves being removed. Fig. 3 is a bottom view of a portion of the table, showing certain mechanisms hereinafter referred to. Figs. 2, 4, 5, G, 7, and S are detail views. Fig. 9, Sheet 2, is a section through line X, Fig. l, and Fig. l0 is a section through line Y, same flghre, Vshowing C in section and the hinged part C in section in a partly-raised position. Fig. ll, Sheet 2, is an end view showing one leaf resting on a hinged section, partially raised.

In said drawings, a, Figs. l and 9, represents the central or stationary part of the table,

and b a storage-place, or an open space adapted to receive the leaves thereof when not in use,

and is located in either or both of the eXtensible sections of the table, as may be preferred.

c, Figs. l, 3, 9, and 10, represents the bottom of said storage-place or open space, of which g are hinged ends, as shown 1n 'section in Figs. 9 and l0, adapted to be raised and lowered at the extremities thereof to raise the leaves on a level with the surface of the table wh en required, said sections bein g raised by means of a ratcheted T-shaped plate, d, Fig. 3, of metal or any other appropriate material, and a spring-actuated plate or tongue, e, 3, 6, and 9, to engage the ratchets of said plate d, to hold the same in the position necessary in raising the leaves to the surface of the table, the number of ratcliets on the plate corresponding with the number of leaves in each receptacle.

d', Figs. 3 and l0, is a knob attached to the plate d, by which said plate is moved from one ratchet-tooth to the other in raising or lowering the leaves; but in lowering the sections c it is only necessary to press upon the springactuated device e, Figs. 6 and 9, which releases the plate d from engagement therewith, thereby avoiding the necessity of putting the hand under the table in operating the knob, as will be understood. Said T-shaped plate d is pivoted to the outside Of the bottom c, as at d?, Fig.

f indicates connecting rods or straps, preferably of metal, one of which is pivoted to the plate d at the end d3 thereof, and the other at or near the cross-head of said plate d, said rods being twisted about one half-turn to bring them into pivotal engagement with straps g, riveted or otherwise secured to the hinged sections c', before referred to, as clearly shown n Figs. 3 and l0; or one strap instead of two may be used; but I prefer two, because of the additional support to the sections c.

h h, Fig. l0, are grooves on the side of b to receive the dowels or projections 7i (one of which is shown in Fig. 7) in the edges of the Lil leaves h3 of the table to securely hold the l leaves in the storage place or space b, so as to prevent them slipping therefrom when they are not in use should the table through inadvertence or other cause be tipped or tilted. from one side to the other. Said projections IOO ing in position to the hook. 7.', and in which braces are pivoted to a projecting plate at o,

said hook rests, The leaves are t'urther held together at their edges and to the table by means ot automatic catches, consisting in l,arranged in positions opposite thc plates o,

the present instance ot' a hook, 7.', Fig. l, in

one ot the edges ot' the leaves 71, and about the center thereof' in the line oli' its length, 1

and a corresponding spring-catch, 7l", secured in a suitable casting, i, Fig'. 5,which is boxed V into the other edges olf the leaves 71 and to a ble, the said catch 7n engages with said corresponding' catching' device, 7.', and locks or f secures the leat` to the table.

side ot' the leaf just referred to has a similar I The opposite catching device, and the next leal raised also has a catch similar to the lirst leat',so that when the leali is adjusted preparatory to closing` over the opening caused by the body of the table being extended the catch 7.a will slip into locking engagement with the catch 7.', t

and so on in regular succession until the lasty leat" is raised. length ot' the table, press upon the spring' c, and thus release the plate 17 and allow it to move the extent ot' one ratchet. 'lhe spring' will t'hen hold it again. Open the table tar enough to allow the dowels in the edges of the leal to be t'ree,and the leafwill drop down being enabled to pass treely through the slot f in the side 71, will thus relieve or unlock itsell' from the spring-catch 7;. Close up thc table again so as to bring another leat' in position, and repeat the operation until the last leat' has been removed.

7 represents side pieces, which are adapted to expand or contract as the table is increased or diminished in its length. Said side. pieces are hinged, as at 7', Fig. l, to the central supporting-piece, n1, ot' the table, to which the central leg or standard is secured. Said side pieces are also hinged to projections adjacent to the space 71, as at I2, Figs. 1 and (l, and are also hinged together, as at 7, and adapted as the body assumes its smallest or normal size to fold together and lie parallel with one another, all of which will be understood by reference to Fig. l.

n n represent braces consisting of pivotallyconnected slats expanding and contracting, as the table is increased or diminished in its length, something after the manner ot the lazy-tongs. Said braces are composed ol 'l`o reduce or shorten the.

Fig. l, secured to the center support, '111, and to l1 at o at one end, the other end having' a reciprocating movement in slotted plates p, Fig.

just referred to, as clearly shown in Fig. l.

lt will be understood that this table ditters from other extension-tal les, in that the body or central portion ol" the table is designed to remain stationary, and when it is desired to enlarge the table b v means ol' the leaves the two ends otl the table are extended, as will be understood.

llaving thus described my invention, what l claim as new isl. An extension-table combining' therein a central stationary portion or body,extensible sections arranged. upon one or both sides thereot', a storage-place lor the movable leaves, the bottom ol' said storage-placehaving hinged end sections adapted to elevate said leaves, hinged side pieces c1mnectingthe central body ol. the table with the said extensible sections, and braces composed ot' pivotally-c1mnectcd slats connected with said sections, all ot' said parts being arranged, combined, and adapted. to operate substantially as described, and t'or the purposes set torth. v

ln an extension -t'able having a place t therein tor the storage ol' the leaves, the combination ot' sections c', hinged or pivoted at one end ot' the bottom piece, r', a ratcheted plate pivoted to the outside ol' the bottom ol' said piece c, connecting rods or straps pivoti ally connecting said hinged sections and said on the pivoted ends c', and the hook 7.', b v t tended, as will be readily understood.

Said

ratchcted plate, and means, 1I', l'or operating said plate, whereby one end ol.' said hinged sections may be raised, substantially as described, tor the purposes set l'orth.

Il. In an extensi1m-table substantially such as described, the ctnnbiimttimi, with a storagelplace l'or the leaves thereot', the walls ol' which are groovcd at 71,01 leaves havingprojections 71 to tit in said grooves, substantially as and l'or the purposes set lorth.

l. ln an extension-table, the ctnnbination, with a storage-place, 71, and extensible sections 1", ot' a series ot" leaves having dowels or projections 71,adapted to slide in grooves /1 in the wall ot' said storage-plzue, and corresponding depressions, 712, in the adjacent leaves, a catch, 7i', and catching device 7:1', adapted to engage with said catch, as described, all said parts being arranged and adapted to operate sul'istantially as and t'or the purposes set forth.

1n testimony that I claim the foregoing l have hereunto set my hand this llth day ot' October, 1R87.
