Pivoted lever caliper brake
First Claim
1. A caliper brake comprising:
- (a) a base,(b) a single pole mounted on said base and normal thereto,(c) first and second identical brake arms having first and second ends,(d) each of said arms having a pole boss extending therefrom intermediate the first and second ends and adjacent an edge of the arm and spaced from the opposite edge thereof and(e) a hole extending therethrough, said pole extended through the holes of said pole bosses with the pole boss of one arm positioned upon the pole boss of the other arm with the holes of said pole bosses in alignment thereby mounting said arms in pivotal juxtaposition,(f) first and second brake shoes each having a friction facing thereon,(g) each of said arms having a shoe boss on the first end thereof, and a hole extending therethrough parallelly disposed to the hole in the pole boss,(h) each of said brake shoes having a pair of spaced flanges and(i) each flange having a hole extending therethrough,(j) first and second pins extending through each of the holes of said flanges of said first and second brake shoes and extending through the shoe boss of the first ends of said first and second arms thereby pivotally mounting said brake shoes on said arms,(k) said base having a stop pin extending upwardly therefrom and parallelly disposed to said single pole,(l) first and second guide pins mounted on said first and second arms intermediate the pole boss and the second end of said arms and extending normal thereto and contactable with said stop pin,(m) means for adjustably positioning each of said guide pins relative to the brake arm for adjusting the pivotal position of said brake arms each to the other, and(n) means interposed between the second ends of said brake arms for pivoting said arms upon said pole and the friction facings thereof together to grip a disc positioned between said friction facings of said shoes and away from each other for release of the disc.

Abstract
A caliper brake including a base having a single pole extending therefrom with a pair of identically formed opposed arms pivotally mounted on the pole. On one end of each of the arms is pivotally mounted a brake shoe, and the other ends of the arms have an air bladder interposed therebetween for moving the brake shoes together. Each of the arms carries an adjustable pin engageable with a central stop pin mounted on the base and extending centrally between the arms for orienting the arms relative to a disc positioned between the shoes for braking of the disc. An air bladder is mounted between the other ends of the arms for pivoting the arms and moving the brake shoes together, the bladder having an intrinsic spring return properties which separate the brake shoes when the air bladder is deactivated.
