In place of using separate leaves for extending a dining room table a recent invention provides an extension top something like the roller top of a desk which will fold under when the table is closed. The table may then be extended to any desired length by merely drawing out the ends. The construction is clearly shown in the cross-sectional view. It will be seen to comprise three sections, a central section and two end sections. The latter are adapted to fold against the central section running in grooves D. The top of the celltral section is formed of two stationary boards A, Connected with each board is an articu- lated beetion B. Each section is formed of a series of bars of keystone form in cross section to permit them to swing toward each other when passing around curves. Fitted lengthwise between each pair of bars is a tube, and a series of springs serve to hold the bars against the tubes. Thus the bars are held in flexible hinged relation to each other. The ends of the extension sections B are guided on tracks C and carried by the end sections .of the table. Both of the tracks curve down under the table top. The track C runs above the track E. A flange F separates the two sections B when they are in their folded position. Stop pins are provided to prevent the parts from being extended far enough to withdraw the articulated sections from their guides. A patent on this extension table has just been granted to Mr. Emory A. Fuller, 27 Lombard Terrace, Detroit, Mich. The number of fatal Alpine accidents during the past summer has been the highest ever recorded. Ninety accidents have occurred, resulting in eighty deaths and twenty-two injuries. About half the killed were guides, and thirty-one were persons spending vacations in Switzerland. Three-fourths of the fatalities were due to falls over precipices. The others were due to snowstorms, avalanches, or lightning.
