Opinion

J. B. McPHERSON, District Judge.

The patents involved in this controversy have to do with trucks for electric passenger railway cars. The type of truck is the “Maximum Traction Truck,” the characteristic features of which are thus described by complainant’s expert upon pages 214 and 215 of complainant’s proofs:

“First. Four wheels set upon two axles, so that the wheel base may be short, and the truck better adapted to round sharp curves without derailment.
“Second. The driven wheels should ho of large size, relative to the other pah1, so as 1o have a high axle, whereby space for a large motor may he afforded; and the side bearing plates and pivotal center of the truck should be over or near this axle, so that the greater part of the weight will he carried on it. and the radiation of these large wheels he as little as possible. And a portion of the weight should be applied to the small wheels, to hold them down upon the track.
“Third. The motor should be supported upon the axle of the driven wheels, so that its weight may contribute to the traction of those wheels, and its power applied to them.
“Fourth. There should he an axle-box frame (sometimes called side beams or bars), being substantial, strong side bars or beams, which are supported [902]*902upon the four axle boxes by parts called saddles, sometimes bolted to, and sometimes made integral with, the frame beams or trusses, so as to produce a strong, unyielding structure, whereby the axles are maintained in parallelism, the axle boxes suitably braced and supported, the endwise thrust of the axles resisted, and which may be used as a partial support for the motor. This frame likewise serves the important function of a foundation or underlying support for the main car springs.
“Fifth. Side and end bearing plates, which immediately support the car, and which are spring-supported on the axle-box frame.
“Sixth. The truck should be constructed in other respects so as to afford an unobstructed space between the axles for the motor, and so as to have a short wheel base; also so as to permit of a low-lying car body,, whereby but few steps will be necessary, and large platforms secured. The brake mechanism should be so constructed as not to interfere with the motor space.”

That the maximum traction truck has greatly improved the art is beyond dispute. Indeed, this truck may almost be said to have made electric traction possible and profitable upon the narrow streets of cities; and no patents, I think, have done so much to improve the art as the patents under consideration. The advantages gained by the use of the Maximum Traction Truck are summarized by one of the complainant’s witnesses, who appeared to have an extensive acquaintance with the development of street-railway transportation, and to understand thoroughly the difficulties that were necessary to be overcome. He stated the advantages as, follows, upon pages 163-165 of complainant’s proofs:

“A large and long car, with large carrying capacity, with steadiness of motion, and consequent ease of riding for the passengers.
“Easy motion on the track, and consequently greatly decreased destructive action on the track and on the ear body. No pitching nor rolling.
“The car body carried so low that access to the platform can be had with a single step (same height as four-wheel car).
“A narrow car body possible without increased elevation.
•“Increased average speed in handling traffic, resulting from low car (with a reduction of liability to accidents) and from increased traction.
“The truck can be used under open cars as well as closed. (Interchangeable between winter and summer cars.)
“Entire center space of the truck open, in order to give easy access to the motor for inspection, repairs,' and removal.
“All the traction possible compatible with the guidance of the trailing wheels.
“One motor only required for each truck.
' “Large driving wheels, giving easy riding and economy of propulsion, with a high speed, and high axles, giving ample space for motors of increased size.
“Small trail wheels, making that end of the truck low, and permitting radiation on curves without striking the car sills or steps.
“Means to hold the small wheels down upon the track in order to prevent their climbing the track on curves or when meeting obstructions, and thus .derailing the car.
“The necessity of absolutely preventing climbing on the side wheels cannot be overstated. They must be kept close down upon the rails, and particularly on curved If allowed to climb, even by a small fraction of an inch, the force of the upward impact might easily increase the climbing enough to cause a derailment, and in rounding curves the trail wheels naturally tend to slide up the track when leading. This had been one of the serious objections to 4-wheel cars. To obviate it, their speed had to be reduced on curves to five or six miles an hour. In 8-wheel cars, with the greater part of the weight on the driven wheels, and a less amount on the trailing wheels, unless proper methods are used the danger of derailment on [903]*903tlie part of tlie small wheels would be greatly increased. To keep the trailing wheels upon the track; and enable them to guide with safety, it is necessary that they should carry a portion — at least twenty per cent. — of the load.
‘‘Total elimination of bolster mechanism.
“By the elimination of the bolster mechanism the eniire space In the center of the truck between the axles may be secured for motor suspension, while retaining a short wheel base, enabling eúrves to be passed with little friction. This also gives less radiation of tlie trailing wheels.
“It is a generally recognized fact that the production of this truck has been as potent as any other single factor in the realization of the electrical transportation system as it exists to-day, and it is obviously not a transitory matter in any sense. On the contrary, it is here to stay.
“How important this type of truck is, may be judged from the fact that the Metropolitan Street-Railway system of New York City, which I believe ‘’lias the largest volume of traille of any street railway in tlie world, has adopted the "Brill Maximum Traction Truck upon their lines.
“Tlie Union Traction Company of Philadelphia is now lengthening its four-wheel car bodies and converting' them into eiglit-wlieel ears, and has recently ordered nearly 200 sets of Maximum Traction Trucks. Tlie Brooklyn roads have adopted eight-wheel cars with the same type of tracks as their standard, and the Third Avenue road in New York Is considering the adoption of large eight-wheel cars on its lines.
"The present tendencies in electric railways everywhere are distinctly towards the adoption of double-truck cars, to the exclusion of those mounted on four wheels. In the suburban traffic the four-wheeled ear is almost obsolete.
