Spot brake structure including a pivoted lever actuator

Claim 1

A brake structure cooperable with a rotor disc to be controlled comprising an elongated sheet metal channel member of generally U-shaped cross-sectional configuration and including first and second opposite, generally parallel side portions for embracing opposite sides of the rotor disc and a connecting substantially closed bight portion extending between longitudinal outer margins of said side portions for overlying a peripheral section of the rotor disc, said first side portion including a free margin opposite from said bight portion and a generally centrally located opening therethrough between the bight portion and said free margin, stator means movably mounted within said channel member and carrying friction pad means substantially enclosed by said bight portion and said side portions for protection from foreign material, an actuating lever having an inner end portion extending through said opening and engageable with said stator means for energizing the brake upon actuation of the lever, said first side portion comprising an outwardly embossed seat portion providing an inwardly open groove extending transversely of said first side portion, across said opening and with an access opening through said free margin, and an elongated pin bearing element insertable into said groove through the access opening from a position outwardly of said free margin and by force fit through an aperture in the inner end portion of the actuating lever for pivotally connecting the lever with said first side portion with the pin bearing element confined to the groove during movement of the lever.
