ternal shoulder on which I seat a berboard disk or washer which intervenes between the plastic body of the tip and the sharp edge of the metal leg. The sharp edge of the metal leg may score and gouge into the iiberboard washer, but it will not cut therethrough. Plastic furniture leg tips fabricated according to my invention will last indenitely.

Other objects, features and advantages of the invention will appear from the following disclosure in which:

FIG. 1 is an axial cross section taken through a plastic furniture leg tip sleeved about a metal furniture leg.

FIG. 2 is a perspective view of the structure shown in FIG. 1.

FIG. 3 is a perspective view of the iberboard washer.

FIG. 4 is a perspective view of a half section of plastic tip lbody.

According to the present invention a plastic furniture leg tip or cup is provided in its side wall 8 and near its bottom wall 9 with an internal shoulder 10 about which the plastic body is thickened in an annular pattern and on which a iiberboard or like disk or washer 12 is seated. The plastic tip is ensleeved or teleseoped over the end of a metal furniture leg 13. The end z14 of the metal leg is conventionally sharply cut otf in its 4 manufacturing process to leave ends 14 with a relatively sharp cutting edge.

But for the berboard washer 12, the sharp edge 14 of the leg 13 would readily cut through the plastic body of Patented Aug. l, 1961 ICC the tip 8 and destroy it. In the device of the present invention, however, the fiberboard washer '12 intervenes between the plastic cup and sharp edge of the leg end 14 to protect the plastic from being cut by the sharp edge of the'leg. The sharp edge of the leg may gouge or score the berboard washer which has suicient resistance, however, to prevent the sharp edge from cutting into the plastic.

The shoulder 10 is desirably spaced upwardly somewhat above the bottom wall 9 of the tip to provide a cavity 15 between the tip bottom wall 9 and the washer 12. The tubular Wall of the metal leg V13, however, is aligned vertically with the thickened portion 1-1 of the plastic tip 8 and thus leg stresses are transmitted through the washer to the plastic body. Because of the recess 15, however, the tip interposes considerable resilience between the furniture leg 13 and the supporting surface such as Hoor 16.

As used in this specification and the appended claim, berboard means both a pressed non-impregnated board made of wood fibers and a board made of vulcanized bers impregnated with resinous material, and all equivalent thereof.

I claim:

The combination with a metal furniture leg having a tubular wall with a relatively sharp cutting edge, of a tip having a plastic body sleeved over the end of said leg, said tip having an internal shoulder aligned with said Wall and a cut-resistant washer Seated on said shoulder and intervening between the sharp cutting edge of said wall and the plastic body of said tip., said shoulder ybeing spaced above the bottom end of said tip to define a cavity between said bottom and said washer, said plastic body being thickened in the vicinity of the shoulder.
