A member of a political party requested the defendant to suspend a political banner, which he furnished, across one of the principal streets within the borough of Dubois, between the Commercial Hotel and the Deposit National Bank. The currents within the above cases have been from main batteries, too costly a source for commercial purposes. The chimney stood thirtyone inches from the sting of the cornice over the road, was twenty-one inches sq. at the bottom, and had a tin flashing from the roof inserted between the courses of brick two or three programs above the roof. The trolley-wire is carried on insulated supports on this conduit, and phone is made with it by brushes on the arm from the automotive above. The advantages are that each automobile is an entire and impartial unit and that the trolley-strains and feeder-system are abolished; however every line constructed has failed, and the trolley-system has been substituted. The defendant put up the banner, at first suspending it by a rope, however the rope breaking, substituted for it a wire cable of the defendant's, and, the plaintiff says, did so with out additional orders.

The proof for the plaintiff was in battle with that for the defendant upon vital points, however we shall state the case because the jury might have found it to be if they believed the plaintiff's proof, because the verdict exhibits they did. At a former trial the plaintiff had a verdict nevertheless it was put aside and a new trial ordered by the Cr cuit Court of Appeals. 906. But because it has been necessary to direct the document to be certified up, it is important additionally to contemplate the merits of the case and to determine whether or not the Circuit Court of Appeals was right with regard to them. As we have now implied, we regard it as too plain for dialogue that the plaintiff's evidence if believed warranted a finding that the defendant undertook the care of the banner while it was up. It hardly is denied that there was proof of negligence, however it ws held by the Circuit Court of Appeals that the defendant's relation to the work ceased when the banner was hung, that it had no further management over it and was not liable for what occurred thereafter. No management is exercised from the vehicles themselves; in actual fact, the trains run with out attendants.

The present for the trolley-wire is carried by feeders, giant wires, which run overhead (or underground in large cities) from the facility-station, and are connected at numerous points with the trolley-wire. A motor may be considered a dynamo appearing to produce an electromotive power e which is reverse in path to the externally impressed electromotive pressure E. The resultant electromotive pressure is E-e, and on this, together with the resistance of the circuit, the energy of the current C relies upon. The success of this system depends on the upkeep of insulation of the wire within the conduit, typically a troublesome downside owing to moisture and dirt, but successfully solved in the cities mentioned. The proportion of series to shunt winding crucial for this end result is dependent upon the relation of the resistance of the armature to that of the shunt coil, and it is an easy deduction from the theory that, when the resistance of the armature is negligibly small, the velocity of a easy shunt- wound motor driven by means of a relentless external electromotive pressure is sensibly fixed, a end result which has been experimentally demonstrated by Mr Mordey (Phil. Mr Reckenzaun's car is carried by two bogie trucks, one beneath every end, and each bogie carries a motor whose axle, positioned longitudinally, drives a central spur-wheel on one axle of the bogie by way of a worm.

A small tunnel or conduit runs under the surface between the tracks, and in it is a slit for an arm which extends down from the car. Under common situations it's possible that the conductor system has a slight benefit over the other on this respect, however the difference will not be materials, particularly as the cost of power is a comparatively small part of the entire working expense of a line. A small electric motor, which hangs beneath the road and is geared by spur and chain gearing to a pair of driving-wheels, varieties the locomotive. The practice is furnished with a continuous conductor from end to finish, by way of which it makes electric contact between the section in front and the part behind, and the motor is included within the circuit of this conductor. If, nonetheless, there are more than one practice on the road, an automated block system is added to stop one from overtaking another by letting the part which a prepare leaves stand insulated for a time.
