TABLE.

Specification of Letters Patent.

Patented Dee. 12, 1916..

Application filed August 24, 1915. Serial No. 47,024.

To all whom it may concern:

Be it known that I, BENJAMIN ZIMMER, a citizen of the United States, and` resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain newl and useful Improvements in Tables, of which the following is a specification.

The object of my invention is to improve the table shown and described in my pending application for Letters Patent of the United States, No. 871,494, filed November' A further and particular object is to provide a table of such construction that the leaves, while capable of extension to increase the size of the table, are wholly concealed when the table is reduced to its normal size.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the' accompanying drawings forming part of this specification, Figure 1 is a plan sectional view of a table embodying my invention, Fig. 2 is a vertical sectional view of the same, Fig. 3 is a plan view of the table extended, Fig. 4 is a sectional view, showing the table extended and the means for moving the leaves, Fig. 5 is a similar view, illustrating the operation of folding the table and concealing the leaves thereof, Fig. 6 is a detail sectional view, showing the mechanism for raising the table top, Fig. 7 is a detail sectional view, illustrating the mechanism for raising and lowering the table top, Fig. 8 is a sectional view on the line -m of Fig. 7, Fig. 9 is a detail view, showing the veneered style of top.

In the drawing, 2 represents the side rails of the table and 3 the end rails, having supporting legs 4 with suitable brace bars 5 between them. Between the rails 2 bars 6 6 and 7-7 are provided, arranged in pairs and spaced apart. A plate 8 is seated on the upper edges of the bars 6 and 7 and secured thereto, preferably at a point midway between the ends of the bars. Upon the outer bars of the pairs I arrange plates 8, preferably of metal, having guide pins 9 in their upper portions to enter slots 10 in depending plates 11 which are secured to the underside of the table top 12, said plates 11 having guide pins in their lower portions mounted to slide in slots 12 provided in the plates 8 and thereby the depending 'plateswll will be guided in their vertical movement. Vhen the table top is in its depressed position, it will rest upon the plate 8.

To raise and lower the plates 9 I prefer to provide levers 13 pivoted at 14 and having links 15 connecting them with the plates 11;. The levers 18 have longitudinal slots 16 therein to receive pivot pins 17 mounted on operating crank arms 18 which are pivoted at 19 on the side rails of the table. These arms 18 are connected with one another by a rod 20 for convenience of simultaneous movement. rIhe arms may also be provided with stops 21 for engaging the upper edge of the levers 13 and limiting the outward swinging movement of the arms. The rod 20 will be beneath and near one of the side rails of the table, where it can be easily reached and operated to open or close the table.

On each side of the table I arrange leaves 21 having their upper surfaces flush with the upper surface of the plate 8, as shown in Fig. 5. These leaves are connected with one another across the table by pivoted bars in the form of lazytongs 22 which, when one leaf is pulled out in one direction, will push the other leaf outwardly in the opposite direction, the bars having a central pivot at 23 on the plate 8. This construction corresponds to the one shown in my pending application, above referred to. These leaves are mounted on bars 22 arranged in pairs on each side of the table and slidable in guides formed between the cross bars 6 and 7 The outer ends of the bars22 are preferably provi'ded with ornamental heads 23 and when the bars and leaves are drawn out, the inner ends of the bars will rest on the underside of the plate 8, as shown in Fig. 4, sufficient space being provided between them to allow the table top to drop down to a position flush with the top of the leaves, as set forth in my former application. It has been found desirable, however, to provide a construction which would conceal the outer edges of the leaves and close the joints between them and the table top when the table was in its contracted or folded position. To accomplish this, I provide a molding 24 having a miter joint with the edges of the table top and depending below the same a sufficient distance to entirely conceal the eXtensible leaves. This flange, if the table had square ends, would project beyond the ends of the leaves when the top was dropped down between them, if suflicient space was provided between the end iianges to receive the leaves when they were pushed inwardly to close the table. I therefore bevel the ends of the leaves, as indicated at 25, Fig. 2, and also curve the ends of the table top and the depending molding or flange to aline with the beveled ends of the lea-ves when they are drawn out to extend the table. This is plainly illustrated in Fig. 2, where the leaves are shown pushed in to their retracted position and fitting loosely between the flanges or molding at the ends of the top. Then these leaves are drawn out their transverse edges will register with the ends of the top and form an oval appearance, as indicated in Figz 3. These leaves will be entirely concealed by the top when they are pushed in and the top dropped down upon them. rl`he upper edges of the bars 22l have notches 26 therein provided with beveled edges 27 and square shoulders 28. Then these bars are drawn out, the moldings on the table top will drop therein and exert an outward pressure against the shoulders 28 to hold the leaves irmly in position. The molding or flange may be mounted on the table top in any suitable way but preferably by rabbeting the molding at 27 to receive a rib 28 on the table top. Y

In Fig. 9 I have shown a table top and molding provided with a suitable veneering 30.

In various ways the details of construction herein shown and described may be modified and still be within the scope of my invention.

I claim as my invention:

l. Artable having a vertically movable top provided at its side and end edges with a depending iiange, the ends of said top being curved slightly and the anges thereon being curved to correspond thereto, leaves normally fitting under said top and gradually decreasing in length from one longitudinal edge to the other, whereby said leaves may fit under said top and between said end flanges and be concealed thereby, the ends of said leaves when they are witln drawn from under said top and the top is dropped down between them forming con tinuations of the end flanges of said top.

2. A table having a vertically movable top, leaves mounted for outward movement' to allow said top to be dropped down between them and in the plane thereof, the ends of said leaves'being curved and the edges of said table top having depending {ianges thereon for concealing the crack between the table top and the leaves when the table is closed, the end fianges of said table top being curved to conform to the degree of' curvature of the ends of said leaves, for the purpose specified.

3. A table comprising a frame having cross bars and a table top, supports centrally arranged on said cross bars and having pin and slot connections therewith, levers pivoted at points intermediate to their ends and having pivotal connections at one end with said support, rocking arms mounted adjacent the side rails of said frame and having pivotal connections with said levers, a rod adjacent a side rail of said table and having its ends mounted in said arms and forming therewith an operating bail and leaves normally beneath said top and adapted to be drawn out to allow said top to drop down between them in the plane thereof.

In witness whereof, I have hereunto set my hand this 18th day of August 1915.

BENJAMIN ZIMMER.
