690 Handley, William, 26 Great Earl Street, SevenEials—Inventor.

Patent break for railway trains, designed to obviate theserious defects of the common railway break. The firstadvantage it presents is an improvement as to the perma-nent way, which is effected by the use of the long shoe;this, by having 18 inches of bearing surface upon therails, will slide over the soft or bad places hitherto madeworse by the application of the ordinary break, the wheelshaving only about one inch of surface. The ends of therails will not be jumped up or flattened by the wheelscoming in contact with them, which is now the case, asthe wheels resting upon the shoe mil in fact press suchirregularities down.

The second advantage is that, in the locomotive de-partment, the wheel tires arc always preserved perfectlycircular; and the shoe, by bearing up the wheel when thebreak is applied, prevents the flat places being formed,and also torsion upon the axles. The wheels, whether ofwood or iron, are saved from being strained, and thetires, rivets, bolts, &c. are not so liable to get loose, anevil which is caused by their becoming heated. Thecarriage frame is also saved from being racked and twist-ed, as the patent break is suspended upon the axle only.This will cause a great saving in the repair of break car-riages. By the adoption of this break, a power is gainedwhen applied to two wheels only, fully equal to the usualbreaks applied to six, a feature of no slight importance incases of danger. This power in retarding a train is alsoalways the same, which is not the case with the commonbreak. The different weights with which the carriagesare loaded are continually altering the position of theblocks, which varies the number of turns of the screwnecessary to apply the ordinary break; while in wet,greasy weather, it is almost impossible to skid the wheels.The patent break can be applied in less time, and withtwo or three turns only of the screw, whereas six or seventurns are required with that hitherto in use. It is alsofree from the usual unpleasant noise, smell, and sensationfrom friction.

Lastly, considerable saving is effected, both in theamount of stock required and in the wear and tear ofrailway apparatus.

The necessity for the introduction of an improvedrailway break is universally admitted by all engineers andpractical men. The breaks in common use are very in-jurious, both with regard to the durability of the wheelsand rails. Timber blocks of poplar wood are made tobear hard upon the peripheries of the wheels, bo as to stoptheir revolution. The result is the grinding of many flatplaces on the tire of the wheels and the abrasion of therails, occasioning frequent renewal.

691 Chesshire, ‘Edwin, Birmingham —Inventor.

Model, showing the principle of an invention for lessen-ing the danger of collisions on railways. This object isproposed to be attained by suspending in bearing sockets,under the centre of the framework of every carnage ofthe train, a strong iron rod or tube with an expanding,head at each end, to be called a “safety buffer,” andmoving, when acted upon, in a longitudinal direction; andalso by attaching at the hinder end of the train a strongvan with a low centre of gravity, for the purpose ofreceiving the first shock of a collision, should it takeplace from behind; the engine tender being made toanswer a similar purpose should the collision occur at thefront. The force of the shock will throw the “safetybuffers ” into one continuous inflexible rod, by means ofwhich its force will be transmitted to the opposite end,
