HERBERT CLINTON SOULE, OF WILKINSBURG, PENNSYLVANIA, ASSIGNOR TO WEST- INGHOUSE ELECTRIC AND MANUFACTURING COMPANY, A CORPORATION OF PENN- SYLVANIA.

Application filed November 8, 1909.

To all whom it may concern Be it known that I, HERBERT CLINTON Scum, a citizen of the United States, and a resident of Vilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Stationary Inductive Apparatus, of which the following is a specification.

My invention relates to stationary inductive electrical apparatus and it has special reference to such apparatus as is cooled by a circulation of air.

The object of my invention is to provide a simple air-blast transformer structure with which a reactance coil. may be mechanically combined, whereby the combination may occupy a minimum amount of floor space and the cooling of the reactance coil may be independent of the cooling of the transformer.

Reactance coils have frequently been associated electrically with transformers and with other electrical apparatus, but no provision has usually been made for cooling them and they have usually been mechanically independent of the transformer.

According to my present invention, I dispose a reactance coil in the air passageway through which the air-blast transformer, with which it is associated, is supplied with cool air, the coil being secured directly to the transformer casing, so that the two devices may be handled. together, and a hood or deflector being provided for deflecting a predetermined amount of the cool air through the reactance coil.

Figure 1 of the accompanying drawings is a partially sectional elevation of a trans former and a reactance coil combined in accordance with my invention. Figs. 2 and 3, are, respectively, a plan view and a sectional elevation of the hood or deflector with which the reactance coil of Fig. l is provided. Fig. 4 is a sectional elevation of a transformer station, showing the usual provisions for forced ventilation.

Referring to Figs. 1, 2 and 3 of the drawings, the structure here shown comprises a transformer 1 disposed in a housing 2, which is mounted on any suitable base 3, and a reactance coil 4, which is secured to the bottom of the casing 2 and is disposed in a passageway 5 in the base 3. The bottom of the housing is open to admit cool air from below and its top is provided With a lid or damper Specification of Letters Patent.

6 which is pivotally secured to a cover member 7 of the housing and has an adjusting lever S, a guide 9 being provided in order that the damper may be locked in any position to which it may be adjusted. The reactance coil may be of any well-known structure comprising, as shown, a laminated core 10, end frames 11, tie-bolts 12 and coils 13. The reactance coil is secured to the casing 2 by means of strips lt which are bolted, at their ends, to inwardly extending flanges 16 or are secured to the bottom of the housing by any suitable means, and which are bent to form a cradle for the coil. The coil is provided with a hood 17, which is clamped to one end of the frames 11 and is provided with a fine projection 18 which terminates in a manhole or removable panel 18 in the wall of the housing 2. The panel 18- is provided with an opening 19, having a flange 20 to receive the end of the flue, and a lid or damper 21 by which the area of the flue out let may be adjusted.

The operation of the combined transformer and reactance coil may be best understood by reference to Fig. 4, in which a battery of transformers is shown mounted directly on the floor 22 of a transformer station, communication being established from a chamber 23 below the floor to the transformer housings through the openings 5. The chamber 23 is supplied with cool air by means of a blower 24, which is driven by an electric motor 25 or by any other suitable means, and the intake 26 of which communicates with the outside atmosphere. \Vhen the motor 25 is operated, the cool air is drawn through the intake 26 and is forced into the chamber 23, in which a slight air pressure is maintained. The amount of cool air which passes through the transformers is dependent upon the positions to which the dampers 6 are adjusted, and the amount of air which passes through the reactance coils depends upon the adjustment of the dampers 21. By this means, the reactance coil may be more cheaply constructed and more economically designed, since its core and windings are thoroughly ventilated, and a separate casing and expensive mechanical parts are unnecessary. Not only is the floor space occupied by the set, no greater than ordinarily occupied by the transformer alone, but, furthermore, the circuit connections are materially simplified, a short rigid conductor being located Within the transformer housing for connecting the two devices together and only one pair'of leads being necessary.

The type of transformer which is illustrated forms no part of my present invention, and those skilled in the art Will readily understand that my invention may be applied to various other combinations of electrical apparatus.

I claim as my invention:

l. The combination with a main electrical apparatus, and a containing casing therefor, of an auxiliary apparatus disposed in the path of new of the cooling fluid supplied to said main apparatus and suspended from the main casing, a hood secured to the auxiliary apparatus and provided With a flue which may communicate With the outer air, and means to regulate the flow of fluid through said flue.

2. The combination with a main electrical apparatus and a containing casing therefor, of an auxiliary apparatus disposed in the path of cooling fluid supplied to said main apparatus and supported by the main casing, a hood secured to the top of the auxiliary apparatus and provided With a flue which communicates With the outer air, and means to regulate the flow of fluid through said flue and through said main electrical apparatus.

3. The combination With an air-blast transformer,'and a casing therefor having an adjustable lid or damper, of a reactance coil suspended from the casing, and positioned in the path of flow of the cooling air Whichissupplied to said air blast transformer and a hood or deflector for the reactance coilhaving an independent damper by which the amount of cool air passing through" the reactance coil may be regulated.

In testimony whereof, I have hereunto subscribed my name this 29th day of Oct,

HERBERT CLINTON SOULE.
