Abstract: 198,714. Vedovelli, E. Dec. 9, 1921. Regulating transformers.-A relay 4 is included in the secondary circuit 3 of a current transformer, and is caused to operate at any desired value of the current in the primary circuit 2 by means of an adjustable magnetic shunt 7. The secondary winding may also be provided with tappings for connecting to the relay. Auxiliary windings, normally opposing each other, may be wound on the limbs of the magnetic circuit between the shunt 7 and the secondary winding, the arrangement being such that if one of these windings is short-circuited, the current in the other creates a large flux through the secondary winding and causes instantaneous operation of the relay. An arrangement for producing successive operation of a series of relays 24, 29. 30, placed at different points of a network supplied from a source 23, is shown in Fig. 4. In this arrangement, if a short-circuit occurs at the point 22, the relay 24 is the first to operate, but if the fault occurs between the points 19, 20 or 20, 21 one of the auxiliary windings 25, 27 on the transformers 20<1>, 21<1> ceases to carry current, while an excessive current flows through the remaining winding 26 or 28 and causes instantaneous operation of the relay 29 or 30.

The clutch W is preferably a skew roller clutch described in Specifications 239,894, 248,183, and 273,382, [all in Class 80 (ii), Gearing, Variable-speed &c.], so that, in the arrangement shown, when outer member F is moved to the left, the clutch W is free in both directions. The member F is splined to slide within the clutch member C, and the drive normally passes from shaft A, through flywheel B to member C, and then through elements F, W, E to shaft D. The member F is connected so as to slide with and turn freely on a sleeve I splined on shaft D. When speed is to be changed, a sleeve Q is moved to the left by a control shaft S. Through levers 0, springs K are compressed and clutch disc C freed. Sliding driving member L of the main clutch is carried to the left until auxiliary friction surface M<1> strikes auxiliary clutch disc M<2> fast on sleeve I. Sleeve I is then carried to the left freeing the second clutch W in both directions. The light clutch M<1>, M<2> remaining in engagement effects a light engagement between fly-wheel B and shaft D, as it were short-circuiting the main and second: clutches. The speed change is then made. On releasing control shaft C, the main clutch is re-engaged after the engagement of the second or one-way clutch W.
