Abstract
Abstract A readily applicable and removable self-contained butt hinge attachment which serves as a limit stop, that is, functions to check the angular spreading movement of the knuckle-equipped leaves. It comprises a C-shaped resilient clip conformingly slipped into place over either one (top or bottom) of the pintleaccommodating knuckles. The bight portion of the clip is formed with a projecting riblike stop shoulder. The spaced edges diametrically opposite the stop shoulder have flat liplike outstanding flanges which straddle and yieldingly contact the leaf which is sandwiched therebetween. An optional split springbiased ring encircles the pintle and has stabilizing fingers embracing the respective flanges.
