' Claims. 7 (CI. 45437) This invention relates to furniture and particularly to non-rotatable pads made of resilient material such as rubber. I I

Itis the objectof this invention to produce a 5 generally new and improved resilient furniture Pad of the simplest and most durable character.

The invention will be betterunderstood upon reference to the accompanying drawing, in which Figure 1 shows a-leg for achairor similar article having a pad of my invention applied thereto.

Figure 2 shows a. sectional view of the device shown in Figure l, the sectionbeing taken along lines 2-2 of Figure 1, looking the direction'of The rubber pad 5 is formed from medium soft rubber tubing stock as [regularly furnished .by'

the rubber factories for numerouspurposes. The stock is cut into lengths as indicated in Figure 2 so as who squeezed in between the projections 3, the fit being tight enough so as to counteract the tendency to roll if the chair is pushed along the floor. The size of theinside of thetubing is such that the pintle 4 may be passed thru the 'openingwithout difiiculty, but not loose enough to form a free bearing fit, the friction of the tight fit assists in preventing undesired rotation. After assembly the remaining end of the pintle is bent or riveted over into a flange the same as indicated inFigure 2 so that both ends are alike and the pad is permanently prevented from'being disassembled fromsthe chair leg after the' riveting operation, the pintle 4 is prevented by friction from rotation within the openings of the two projections 3 and the pintle 4 with the rubber pad is sufiicient to prevent rotation of the pad. When one side becomes worn, it'ispoS- sible to twist the pad around to turn a new side to the bottom, so that it maybe completely worn out all around before the metal projections come in contact with the floor.

When the new pad is squeezed into w 'placebetween the projections 3, the friction together with the normal resiliency of the rubber 35 will hold'the-pad in place.
