EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 270,128, dated January 2,1883.

Application filed July 28, 1881.

To all whom it may concern Be it known that 1, CLARK RoBINsoN, of Eau Claire, in the county of Eau Claire, and in the State of Wisconsin, have invented certain new and usefullmprovements inExtension- Tables; and I do hereby declare that the following is a full, clear, and exact description thereof,

drawings, making a part of this specification, in which- 1 Figure l is a perspective view of my table closed together. Fig. 2 is a like view of one end of the same extended, the supplemental leaves being in .position for raisin g to' engagement with the top. Fig. 3 is a perspective view of the same after said supplemental Fig. 4 is a central longitudinal section of the table as shown in Fig. 1. Fig. 5 is a like view of the same arranged as seen in Fig. 2.- Fig. 6 is a longitudinal section of said table as shown in 00 of Fig. 4 and Figs. 8 and 9 are perspective views of the lowerside of said table, and show respectively the relative positions of parts when the same is closed together and when extended. I

Letters of like name and kind refer to like parts in each of the figures.

The present invention relates to that class of extension-tables in which movable leaves are connected with rails sliding in ways of a stationary table-section, so that by raising said said stationary section the extension of the table is effected, provision being also made for depressing the leaves and sliding them under the stationary table-top.

The invention consists in a stationary tablesection having side rails provided with two sets of parallel grooves, in which are fitted bars or slides adapted to move in opposite directions from the center of said stationary table-section, and carrying movable leaves connected with the bars or slides by pivotedlinks. The inner ends of the bars or slides are cut away or reduced in height, so that when the table is contracted saidba'rs will overlap each other, and thus permit the leaves carried by said bars to lie close together heneath the stationary table-top.-

In the annexed drawings, A and A repre- (Model.) I

sent two side rails which are arranged in parallel lines, and are connected together at their ends by means of two cross-bars, B, and are supported by-ineans of fourlegs, G, thatare secured at the points of intersection of said parts, the whole forming the frame of a table. The frame thus constructed furnishes support for a top,D, which extends nearly to each end, and has such width as to give the usual projection of its edges over the sides of. said frame. Said top is raised above said frame a distance slightly greater than its thickness, and is sustained in such position bymeans of a number of metal bars, E, which at suitable intervals are attached to and extend between the lower side of said top and the outer face of each rail A,-and from the latter are extended outward, upward, and then inward in straight lines, as shown'in Figs. 1, 2, 3, and 7, so as to leave between said top and the upper edges of said siderails,.A, a space corresponding to the thickness and width of said top D. Within the inner face of each side rail, A, are provided two parallel longitudinal grooves, a, which grooves extend the entire length of said rail, and each receives a correspondingly-shaped tongue,f, that is attached tothe side and forms part of a slide, F. The slides F are arranged in pairs, which are connected together at their inner and outer ends by means of two cross. bars, G and H, respectively, and upon the latter is secured a supporting-leg, l, which corresponds in shape and length to the like features of the legs 0. The slides F haveequal vertical dimensions, and those at one end have their tonguesfarranged near their upper edges for engagement with the upper grooves a,

while the opposite slides have their tonguesf 0 tween the two slides.

Upon the upper edge of the cross-bar H at 7 each end is secured a leaf, I, which corresponds 2 cranes in position to and when closedinward,as shown I from position, that they are not liable to dein Figs. 1 and at, forms a continuation ofthe top D, the abutting edges ofsaid parts being rabheted to make the engagement more perfect.

hen the sliding ends of the table are drawn,

out-ward the space between the top]) and leaf lfiat each end is filled by means of one or more supplemental leaves, K, which are fitted to and form continuations of said parts, as shown by Figs. 3 and 6.

In order that the leaves K may be connected with the table and readily moved into or from position, each leaf has secured upon its lower face a cross-bar, it, which corresponds in position to the slide F immediately below, and upon the inner lace of said cross-bar and slide are pivoted two bars, L, that have such length as to cause them, when arranged vertically, as seen in Fig. 6, to hold said leafin the exact position-necessary for engagement with the leaf 1 and top l),from which position said leaf K, by a lateral and inward movement, may be changed to that shown inFig. 5, its lower tace resting upon said slides, and its upper face rangement or displacement, and that when not in use they occupy no space that would be available for other purposes.

It will be manifest that by connecting movable leaves with lap-joint slides as herein shown said leaves, when'stowed under the table-top, are permitted to lie close together, thus taking up less space than if the meeting ends of the rails abut together, and enabling a larger number of movable leaves to be used with a stationary table-top of a given area.

Having thus fully set forth the nature and merits of my invention, what I claim as new 1s In an extension-table, the combination of the stationary middle section having side rails provided with 'top and bottom grooves, slides or bars moving in the grooves of the said rails and having overlatming or reduced -end portions, the vertically-adjustable leaves,

and thepi voted links for connecting the same with the slides, with the table-top supported above the side rails, the end connecting-bars,

and supporting legs of the various sections,
