It will be ob-served that the device has the doublemerit of simplicity of construction whilethe joints are easily reached. TRIPLE VALVE. Mr. R. A. Blackall, Edgewood , has patented an improved triplevalve and assigned it to the Westing-house Air Brake Company. No. 851,-373. The device embraces a combina-tion with a quick-action triple valvehaving means for increasing the brakecylinder pressure above that of thetrain pipe in emergency IMPROVED TRIPLE VALVE. and means for gradually equalizing thefluid pressure upon opposite sides ofthe triple valve piston when the pistonis in normal emergency position. Afeature of the device is a small leakagegroove in the wall of the triple pistonchamber, and means for limiting the movement of the piston to this posi-tion. CAR TRLXK. Mr. A. F. Ostrander, Paterson, N. J.,has patented an equalizing device forcar trucks. No. 851,371. Tlie combi-nation comprises a car truck furnished CAR TRUCK WITH with side frames having pedestals forreceiving journal boxes and equalizerbars adapted to rest on the journalboxes, and coiled springs interposedbetween the outer ends of the bars andthe side frames of the truck. There isa lever arranged at each side of thetruck provided with a lug, a bearingsecured to the side frame and engag-ing the lug, and yielding members in-
