John Askwith, of Birmingham, Conn., has) taken measures to secure a patent for the above. Instead of the ordinary brake blocks; the inventor employs swinging or movable shoes, which extend from the frame of th truck to the rail, and have flanges which read below the top of the rail, and being on the in side of it act in a manner similar to the flan ges on wheels. These shoes therefore pres upon both the wheels, and also upon the rails thus lessening the wear and tear by exposing a greater surface to be acted upon; the mair object attained is safety, for besides the bene-iicial tendency of the flanges should an axl break, the shoes will fall on the track anc sustain the car. Two sets of knuckle-jointed levers are used to work the shoes, that set im- mediately connected to them being horizontal, while the others are vertical, and besides joint ing on to the former, are also connected to a cross piece. A chain and windlass give the required tension, and one part ot the drum on which the chain winds is conical in order that it may be operated with rapidity whilst slack. That the brake may be applied as tightly or as loosely as desired, there is employed a ratchet wheel having teeth on both the cylin drical and flat surfaces, so that by using a double-toothed pawl the chain maybetight-
