An ingenious electric brake, for which a number ofadvantages are claimed, has recently been invented byE. B. Skinner, of the Ogden City Street Railway, ofOgden, Utah. An important feature of the invention isthat to set the brake the electric current is only used.

The horizontal plunger, B, which is so connectedo the brake beams that a movement to the left sets thebrake shoes, moves inside of a solenoid wound on a brassor copper tube with heads of the same material. Withinthis solenoid is a spring which normally holds the plungeroutside the solenoid. A smaller, vertical solenoid, withplunger, is also provided, as shown. The end of thisplunger is directly connected to a long lever operating orpressing against a shoe, shown at S, which bears againstthe plunger, N, with such force as to hold it rigidly in
