The outer end of the sageways I! adapted to be aligned, since the portion 40 may be beveled as shown at 44 in Fig:

In this manner the bearingportion 25 of the anti-friction unit is rotatably assembled upon the sleeve portion 40 with a slight longitudinal movement between the flange 45 and the shoulder 42. qt course the race 28 rests uponv the wear resisting shoulder 42, as is well shown in Figure 4. It is to be noted that the flange portion 45. does not project beyond the housing flange 31." g In the assemblage of parts the portion 4| the bushing is driven into the socket or counterwith the end surface of the knuckle [5, although it may lie slightly beyond the outer end surface of the knuckle, so that should the bearing not op- I erate properly, as when the raceway-becomes clogged with dirt, or the ball becomes broken, or the butts be placed on the door out of alignment, causing relative rotation to take place between the facing surfaces of the race and shoulder 42, the major support will be placed upon the wear resisting shoulder 42 and" with little tendency to wear away the knucklef I am well aware that it has heretofore been proposed to use bearings of the general character shown in my invention. However, it has not heretofore been proposed to use an attaching bushing or sleeve in a compact unitary assemblage with the bearing portion of the anti-friction device in such relation that there will be small likelihood of loss of anyof the parts while'independent of attachment to the hinge. Furthermore, it is a very important characteristic that the wear is taken upon a wear resisting portion of the unit and not upon the end of the knuckle to which the unit is attached. This enables a more efiicient working-hinge wherein theltolerances are practically uniform, so that there is small likelihood of sagging of the load, due to wear upon the hinge parts, and practically no maintenance in order to assure efficient operation is negligible. Various changes in the shape, size, and arrangement of parts may be made to the form of invention herein shown and described, without departing from the spirit of theinvention.

I claim:

1. In a hinge the combination with separate leaves having pintle receiving knuckles and a con-' necting pintle passed therethrough, an anti-friction device interposed between the adjacent ends of knuckles of the opposed leaves and including races and an anti-friction element therebetween, and a wear-resisting member of better wear resisting material than the knuckle non-rotatably anchored in concealed ,relation within the end of a knuckle where the strain is received and having a race of the bearing resting thereupon. I

2. In a hinge section the combination of a a knuckle having a pintle receiving passageway ment upon said wear resisting shoulder.

' 3. In a hinge section the combination of a knuckle having a pintle receiving passageway therethrough, a bushing sleeve anchored in said pintle receiving passageway and having a reduced sleeve like extension projecting beyond an end of the knuckle, said bushing at the end of the knuckle from which said extension projects having an annular shoulder lying substantially flush with the adjacent end of the knuckle, and an antifriction bearing rotatably attached to and mounted upon said reducede'xtension .of the bushing including a pair of races with, anti-friction bearing members disposed therebetween, one of said races resting directly upon said annular shoulder and-the other having. the extreme end of said extension of the bushing overturned thereupon to prevent removal of the anti-friction device from said extension.

4. In a hinge section the combination. of a knuckle having a pintlej receiving passageway therethrough and a counterbcre at an end thereof, a bushing sleeve including a thickened body portion anchoredin said counterbore and a reduced sleeve-like extension projecting therefrom beyond the adjacent end of the knuckle, said bushing having a passageway therethrough of substantially uniform diameter and providing at the juncture of the body with said extension an annular shoulderlying substantially flush with the said adjacent end of the knuckle, and an antifriction device rotatably mounted upon the said extension of the bushing including a pair of races with ball bearings ,therebetween, one of the races restingon said shoulder and the extreme end of the extension ofthe bushing being overpeened upon the other race to preventlongitudinal detachment of the anti-friction device from said bushing. I

5. A hinge comprising leaves with co-acting knuckles, ;a pin removably mounted -in said knuckles for connecting the leaves, an anti-friction unit between the facing surfaces of the knuckles of the leaves, and a wear resisting member non-rotatably anchored upon the knuckle which receives the strain incident to support-of a load, having the anti-friction unit resting thereon whereby to receive wearincident to relative rotation between the anti-friction unit and said wear resisting member, said wear resistlng'memher being of metal more resistant to wear than the material of the knuckle.
