We claim: n I

1. The process herein described of'making a leaf of a hinge, saidprocess consisting in forming a blank with a rounded enlargement at one side, cutting the blank into sections the width of a leaf of the hinge, cutting the enlarged portion to form knuckles, then rolling the blank upon itself at the enlarged edge to form aprotecting connecting section the width of a leaf, said section having a stop for the other leaf of the hinge, when the hinge is assembled.

2. The process herein described of making a hinged leaf, said process consisting in first forming a blank with an enlargement at one side, cutting the blank in sections the widthof a leaf, then cutting through a section of the enlargement to produce two two knuckles spaced apart to fit in,

, blank to form knuckles,

ing a leaf of a wrou the enlargement on an a leaf of a hinge,-said process consisting in forming a blank'bent at one side and having a longitudinal enlargement, cutting the enlargement parallel to the bent body of the then rolling the enlarged end of the blank so that the end will be rounded and the knuckles will fit a ainst a portion of the rounded section, and nally. perforating the knuckles for a pintle.

4. The process herein described of formht metal hinge, said process consisting in 'orming a blank bent at one side and having a longitudinal enlargement at said side and an enlarged portion, which eventually inclined line substantially parallel with the incline of the blank to separate the enlargement to form knuckles, then rolling the blank at the enlargement so that the inclined portion of the blank will form a rounded closure for the hinge.
