ALBERT WANNER, JR., OF NEW YORK, N. Y.

FOLDING-LEAF TABLE.

Application filed February 5, 1915.

To all whom it may concern:

- Be it known that I, ALBERT WANNER, J r., a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Folding-Leaf Tables, of which the following is a specification.

My invention relates to folding leaf tables, and its object is to provide means whereby the leaf or leaves of such tables when extended may be held in a state of practically absolute rigidity, both in respect to upward or downward pressure applied to the leaf, and so to construct the parts that this feature will remain unimpaired throughout the life of the table.

According to this invention there is provided, in combination with the fixed member and folding leaf member of a table top structure and a leaf supporting arm underlying and crossing the adjoining edges of said members and bearing against and pivoted to one of them to swing in a horizontal plane clear of the other, means binding said arm and the other member against relative up or down movement.

The invention contemplates the inclusion, if desired, in a table thus characterized of one or more of the following advantageous features, to wit: That the said means shall bind together the arm and each of said members against relative up or down movement; that the said means shall have a wedge action in binding; that said means shall extend outwardly from a point relatively close to the pivot of the arm; and that in conjunction with said means there shall be employed means .to releasably lock the arm against return when the binding means is acting.

The accompanying drawings show the invention in connection with a table of a type having its top structure comprising a rectangular center part and four leaves hinged thereto, but this is obviously immaterial, as the number of the leaves may be more or less.

In said drawings, Figure 1 is a perspective view of the table; Fig. 2 an underneath plan view of its top structure, the

supporting part of the table appearing in horizontal section and the leaves being extended; Fig. 3 is an enlarged fragmentary view substantially like Fig. 2, excepting that one leaf is in folded position and the supporting arm of another appears partly with drawn; F ig. l is a view substantially on the line a2a in Fig. 3, looking in the direction of the arrow A- in said Fig. 3, and the leaf supporting arm being shown moved inward somewhat farther than in said figure; Fig. 5 is a sectional view on the line y-g in Fig. 3, also looking in the direction of the arrow A in said figure; Fig. 6 is a sectional view on the line z-z in Fig. 3 looking in the direction of the arrow B in said figure and showing the end of the arm broken away; and, Figs. 7 8 and 9 illustrate details.

To the sides of the fixed rectangular center part a. of the table top are pivoted in the usual manner, as by hinges b, the leaves 0 which, when extended, stand in the same plane as the center part and which, when folded, lie under and flat against the under side of the center part.

The center part is supported by any suitable frame, such as the pedestal (Z having horizontal crossed arms 6, halved into each other (Fig. l) to which the center part is secured directly by screws 7, or otherwise. Arranged parallel with the sides of the center part and secured in place in any desired manner in the angles formed by the arms 0 are the fixed strips g. Immediately outward of these strips each arm 6 is reduced in thickness, as at it, by recessing it on the upper side.

Each leaf supporting arm 2' has one end forked, as at 9', and receiving the thinned portion h of an arm 6, and it is pivoted thereto by a screw l: or otherwise. These screws are driven into the parts before the table top is secured on its frame, so that when the latter is in place they are not removable. Each arm swings from a position where it is in contact with a plate spring Z suitably secured to the adjoining strip g, in which position an elongated recess m in the outer face of the arm is adapted to receive the edge of the corresponding leaf and thus support the same, folded, to a position where It is highly desirable to provide means for rigidly supporting or reinforcing the leaves of folding leaf tables against either up or down movement when extended, and especially folding leaf tables of the small round type whose leaves are subjected to frequent strain in the attempt to move them about by lifting them by their extended leaves or by persons resting against or upon the extended leaves. The reinforcing means should be of such character as to hold the leaf rigid not only when theparts are new, but permanently. To these ends, assuming that the supporting arm is pivoted to the center part of the table top structure, I provide the devices shown in Fig. 7 which when the arm is extended bind the arm immovably against the under side of the leaf, and in the preferred form employ one or more of similar devices to bind the arm immovably to the center part. These are so formed that when the arm is forced outwardly'into engagement with them they cam or wedge the arm against opposing surfaces, as of the leaf and center part, so that the arm becomes fixed not only to the leaf but to the center part to a degree making the support afforded by the pivot of the arm almost a negligible quantity, excepting that it coacts in the best form of the invention with the aforesaid locking pin it to prevent the arm possibly working inwardly clear of said devices. These devices are preferably arranged in a line which is parallel with a radius of the pivoting pin of the arm and with the nearest one to said pivot relatively close thereto, so that they thus progressively come into binding relation to the arm as the latter is swung outwardly and eliminate any possibility of the arm, should it sag slightly, working under any of said devices instead of V properly ngaging therewith.

The device shown in Fig. 7 is a metallic fitting having a base 3), provided with holes for screws 9 to secure it in place, and an integral upstanding laterally projecting tapered stud or projection 7. When in place as shown in the drawings, the stud r is adapted to enter a tapered hole 8 in the arm when the latter is swung outwardly, the taper of the stud and hole serving to cam or wedge the arm upwardly against the surface above.

T reduce the wear at either the holes 0 or the holes .9 I prefer to drive a staple t into the wood at the side of hole where the wear comes; see Figs. 8 and 9.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A table including a top structure having a fixed member and a leaf member hinged to one side of and foldable under the fixed member, a leaf supporting arm underlying and crossing the adjoining edges of said members and bearing against and pivoted to one of them to swing in a horizontal plane clear of the other, and a binding device for the arm secured to the underside of said other member laterally of the arm and having a binding portion projecting toward the arm and'formed' with an upper beveled surf-ace, said arm having a downwardly facing surface adapted to engage over said beveled surface of the binding device to bind said other member and arm together.

2. A table including a top structure having a fixed member and a leaf member hinged to one side of and fold-able under the fixed member, a leaf supporting arm underlying and crossing the adjoining edges of said members and bearing against and pivoted to one of them to swing in a horizontal plane clear of the other, a binding device for the arm secured to the under side of said other member laterally of the arm and having a binding portion projecting toward the arm and formed with an upper beveled surface, said arm having a downwardly facmg surface adapted to engage over said beveled surface of the binding device to bind said other member and arm together, and means to latch the arm against pivotal movement when engaged by the binding device. A table including a top structure having a fixed member and a leaf "member hinged to one side of and foldable under the fixed member, a leaf supporting arm underlying and crossing the adjoining edges of said members and bearing against and pivoted to one of them to swing in a horizontal plane clear of the other, and wedge means binding said arm and the other member against relative up or down movement and extending from a point relatively close to the pivot of said arm longitudinally of said arm.
