envnnsrnnn TABLE. Y

To all whom it may con-cam Be it known that 1, Louis E. BINSFELD, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Reversible Tables, of which the following is a specification.

This invention relates to table tops, and comprises especially means for reversing the table top sections or leaves for the purpose of exposing either side thereof. One side of the leaves or sections may be highly polished for special use and the other side may be rough for use as a kitchen table or other inferior purposes. The table top is capable of extension, but the extensible features are not particularly pertinent to the reversible features to which the invention is particularly directed.

The invention is particularly applicable to the leaves or top sections of a round table, and is so illustrated. Each leaf or section is mounted on a pivot so that it will turn on a vertical axis, and the pivot is connected to the leaf by a hinge, so that it will also swing on a horizontal axis, and in reversing each leaf it is first swung on the hinge to an upright position and then turned around on the pivot at the center to permit it to be swung down again on the top frame with the opposite side uppermost. Means are provided for raising the leaf above the surface of the table, so that while it is being turned on its pivot it will not contact with or scratch the surface of the opposite leaf.

The invention is illustrated in the accompanying drawings in which- Figure 1 is a top view of the table. Fig. 2 is a similar view with one of the leaves in the act or position of being turned. Fig. 3 is a cross section showing the inner edge of one of the top sections. Fig. 4C is a similar view with the leaf elevated in position to be swung around. Fig. 5 is a plan of a latch mechanism for holding the leavesin adjusted position. i

Referring specifically to the drawings, 6 indicates the ordinary extension slides of a table, which will be supported on the legs in any suitable way, and upon these slides are mounted respectively base frames or sills 7 and an edge frame 8, which latter forms a boxing under the table leaf. These leaves or sections are indicated at 9, andthe operation of each is identical. Each leaf 9 is Specification of Letters Patent.

hinged at the middle of its inner'ed ge, as indicated at 10 (the hinge being sunken in the edge) to a pivot pin 11 which is movable up and down in a sleeve 12 located at the center of rotation and fixed to the adjacent sill 7. An arm 13 is pivoted at one end to the sleeve, conveniently by extending the sleeve through a hole in the arm, and the out-er end of the arm is turned up and oted at let to the edge of the leaf, at the corner where the circumferential and diametrical edges meet, the pivot 14 being substantially concentric with the pintle of the hinge 10. By reason of this construction, the leaf 9 may be swung'up vertically and reversed to place either side uppermost. The pivot 11 also permits the leaf to be swung around on a vertical axis formed by the pivot, and illustrated in Fig. 2, and in order to guide this movement the semi-circular casing or side piece 8 is provided on the inside with a grooved track 15 extending around the same, and this is engaged by the head 16 at the end of a bracket 17 fastened to the underside of the arm 13.

Before turning the leaf on the vertical axis it is desirable that one side thereof be lifted so that it will clear the top surface of the opposite leaf, as shown in Figs. 2 and 4, when it is being swung around, and to accomplish this I provide a wedge 17 which slides in a guide 18 secured to the side of the sill 7 and which works through a slot in the tube 12, and under the lower end of the pivot pin 11, as shown in Figs. 3 and 4:. This wedge may be slid either way by means of a lever 19 which is fulcrumed on the sill 7 and connected to the wedge by a link 20 and projection 21. When the wedge is pushed to the left, as in Fig. 3, to permit the pin to drop, the lever 19 folds or lies within or under the edge of the leaf. When the wedge is pulled to the right, as shown in Fig. 4, its inclined edge, acting under the pin 11, lifts said pin, and thereby raises the .leaf so that when swung around it will clear the top of the other leaf.

To latch orhold each leaf in position I provide the latch devices shown particularly in Fig. 5, which mechanism is located or housed'within the leaf, which will ordinarily be made'of two boards spaced apart, and indicated at 22 in Fig. 3, with suitable edge or spacing pieces 23, the mechanism shown in- Fig. 5 being housed between the boards wood. The latch devices comprise spring pins 2e projecting at the edge of the leaf in position to engage in the holes in bracketsor keepers 25 fastened to the semi-circularframeS, saidbrackets projecting upwardly l The pins.

beside the edge of the table top. are connected by rods 26 to a bell crank lever 27 which is pivoted at 28 and theiend 29 of whichprojects through an opening 30 in the edge of the leaf. When the leavesare pushed together as shown in Fig, 1' this projecting end 29 on one leaf enters a recess 31 in the meeting edge of the other leaf. Vfhen the lever 29 is tu'rned'by pushing in the projection 29, the pins 24 are drawn in and disengaged from the brackets 25, so that the leaf is then free to he swung up and turnedaround.

In operation, to reverse the leaves, the :top is pulledrapart slightly, as indicated in Fig. 2. The latches 2a are then disengaged as above described, and the leaf is swung up to vertical position. The lever l9'is then pulled out which shifts the wedge 17 to the left and lifts the leaf, as shown in Fig. l; Then the leaf is turned on its pivot 11, as indicated in Fig. 2, half way around, and the leafis then swungdown to'its original position, but with the opposite side uppermost, after which the wedge 17 is moved to the left to lower the leaf and cause the latches 24: to engage in the brackets 25. In this rotary action, the leaf is carried by the arm 13 and the pivot 11, the T-head 16 traveling around in the guide 15. The opposite leaf is then reversed in similar man- .ner, .and-itheitop sections may then be pushed together. Onjif an extension table be desired additional leaves can be put in place middle. r 1

hat I claim as new is:

table top, the combination of a supporting frame having a semicircular guide, a central vertical pivot mounted in the frame, a leaf hinged to the top of said pivot, anda swinging supporting arm pivoted concentrically with said pivot and conin the nectedto the edge of the leaf, said arm having a projectingfpart which slides in said guide when the'leafisturned onthe pivot;

2. In a table top, the combination of a supporting frame a central vertical pivot pin thereon, a leaf hingedto the top of'said pin, andjmeans' engaging under the'pinto lift the, same and raise the leaf, said means comprisinga wedgeslidable on the frame and' on which the pin rests.

3. I'n' a tabletop, the combination of a supportingframe, formed in two extensible sections, a vertical pivot mounted on each section", a pair'of leaves each of which is hinged at its meetin'gedge'to eachpivot, so that it may be turned with the pivot and also reversed with respect thereto, and means to 'lifteach leaf, to clear the other leaf as it is being turned.

In testimony whereof, I affix my signature in presence oftwo witnesses.
