. Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . he two parts ofthe transmission were separated, the primary part—thepump—being attached to the prime mover, and the sec-ondary—the motors—acting directly on the drivingwheels. The pump and the motors were connected bypressure and suction pipes, the whole arrangement resem-bling very much an oil-electric locomotive with motorsdirectly attached to driving axles. The locomotive exerteda tractive effort of 12,000 lb. at starting and 3000 lb. The gear permits an infinite change of speedfrom zero to maximum. The Universal Engineering Corporation has appliedthe variable-speed gear to a passenger rail car which hasbeen in service on the N. Y., N. H. & H. Railroad forthe last two years. A similar locomotive with a 75-hp. Diesel engine and\\illiams-Janney transmission was built some years agoby Mckers in England, and has been since in continuousservice doing switching work in the \ickers plant atBarrow-in-Furness. At the Exhibition in Seddin. < u-rmanv, in 1924, the. Fig. 3—The Huwiler Gear Ilerliner Maschinenbau (vormals L. Schwartzkopff),of Berlin, exhibited a 0-4-0 Diesel locomotive with an oiltransmission of a new design known as the Huwiler gear(Fig. 3). This latter consists of a hydraulic pump andmotor, Ixith of the vane type, similar to the Lentz gearbut differing from it in that the pump delivers an infinitelyvariable quantity of oil to the motor, thus j;)ermitting aninfinite variation in speed. This is obtained in the follow-way : Bushing 4 with extensions fits into the pump piston1 and into the space between vanes 2. and can Ix* displacedlongitudinally between the vanes so as to release longeror shorter vane working surfaces. The bushing with ex-tensions rotates together with the i)ump piston and )Ut the dis])laccment of the former is cnnlrolled by anoutside fixed wheel.
