. American engineer and railroad journal . f thelevers as the wear of the slices increases. The invention illustrated herewith has reference particularlyto the latter method, and consists generically in interposingbetween two levers of the system a connection which, so long 96 THE AMERICAN ENGINEER I I i hru iry, as the throw or extent of movement of the levers is normal,will remain inactive, but which, when the movemenl of the levers, or either of them, increases by reason of Black In therigging, operates to shift, the fulcrum of the lever which hasa stationary fulcrum. Specifically the invention consists in connecting the livelever 2 and the dead lever 1 together by means of a rod, 5,having a connection with one of the levers which allows it tomove independently oi the lever in one direction, and causesit to carry the lever with it when moved in the opposite direc-tion, and which rod is automatically extensible so that any in-crease in the movement of the live lever due to slack willcause the dead lever to shift its \y fig a THE HINCKLEY BRAKE SLACK ADJUSTER, Fig. 3 is a side view, in which 1 indicates what is common-ly known as the dead lever ; 2 the usual live lever ; 3 a por-tion of the brake operating rod ; 4 a connecting rod securingthe two levers together for operation in the ordinary manner. li denotes a guide-rod and support for the adjustable ful-crum of the dead lever 1. It is firmly bolted at its inner endto any convenient part of the truck or framing, as indicatedin the drawings at a, and is preferably made hollow or tubularfor lightness and strength. A sleeve! 16, encircles this guide-rod and slides freely to and fro thereon, and the outer end ofthe rod is pieferably provided with a flange,/, to prevent thesleeve from going off the end of the rod. Cast or formed in-tegrally with this sleeve is a fulcrum block, b, having a recessor opening, r, therein to form a keeper for the upper end ofthe dead lever. This block carries an automatic grippin
