HERBERT I. FINCH, OF ST. LOUIS, MISSOURI, ASSIGNOR TO THE EMERSON ELECTRIC MANUFACTURING COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF MIS- sonar.

REVOLVING VENTILATING-FAN.

Specification of Letters Patent.

Patented May 28, 1918..

Application filed July 13, 1916. Serial No. 109,146.

To all whom it may concern:

Be it lmown that I, HERBERT I. FINCH, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Revolving Ventilating-Fans, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements in electrically operated rotary fans of the type wherein one or more fans with independent motors are arranged for revolution about a mounting or support for the purpose of distributing the fans influence. The revolution of fans of this character has been obtained in different fashions, most commonly through the reaction of the fan blades upon the air. It is the principal purpose of my invention to provide a novel revolving fan construction wherein the revolution o f the fan is obtained by a special form of driving mechanism which is actuated by one of the fan motors.

A further objectof my invention is to provide a form of mechanism whereby this result is obtained, and wherein the fan together with its actuating motor is adjustable to difierent angles relative to the support about which it revolves.

A further object of my invention is to provide a mechanism which will secure the operative revolution of the fan at a speed which will be constantly in definite predetermined proportion to the speed of operation of the fan motor and which, by virtue of that fact, can be accurately controlled as to speed of operation.

A further object of my invention is to provide a fan construction wherein a plurality of fans are driven each by its individual motor, the motors being independently adjustable to different inclinations and all of the motors being revolved about a supporting member by power derived from one of the fan motors.

A still further object of my invention is to provide a construction which will secure acontinuous and thorough lubrication of the operating parts upon the actuation of the revolving mechanism.

Another object is to improve generally upon the construction of fans of this character with the purpose of providing a sim ple, strong, durable, economical and easily adjusted apparatus.

Other and further objects will be obvious or pointed out hereinafter.

In the accompanying drawings, I have shown for the purpose of illustration one form of my invention embodied in a ceiling fan, that is, a form in which the device is arranged to be supported from above, as from a ceiling. It is obvious, however, that the invention -may also be embodied in a structure designed to be sup orted upon a column, or in other suitable ashions.

In the embodiment herein. i1lustrated Figure 1 represents a side elevation of the device; l

Fig. 2 a top or plan view;

Fig. 3 a vertical section substantially on line 33 of Fig. 2; I

Fig. 4 a horizontal section substantially on line H of Fig. 1;

Fig. 5 a detail in section substantially on line 5-5 of Fig. 4.;

Fig. 6 a detail illustrating the terminal connection arrangement;

Fig. 7 is a detail showing a fragmentary elevation of the revoluble frame member;

Fig. 8 is a detail showing a fragmentary side elevation of a motor arm.

Referring to the various parts by means of the reference numerals, it will be understood that 1 represents a supporting connection which may also form an outlet conduit for the electrical wiring. Supported thereon and secured thereto by suitable means 2, is a pedestal member 4. This pedestal member includes the socket portion 5, which engages the supporting member 1, the cover plate 6, which extends annularly from the socket member, the bearing portions 7 and 7 5 which form a sleeve-like member extending axially fromv the socket and cover CQUS'E iiteriim r "f tiiig i n r i; tiicloscenti ,i th

Iii he case of the arm 11;; which is ztence this adjustment is 1 the movehiiity of the rei tive to the fiieti nmochite any desired c to tive tc the axis of 5 the Irame and thence up to the chamber 19. When the mechanism is at rest the lubricant Will feed downwardly through the spiral groove from the chamber 49. Inasmuch as the contact of the housing portions 26 upon the annular flanges 20 forms a completely inclosed chamber about the gearing, all working parts will be subjected to thorough lubrication without opportunity for the escape of the lubricant.

The current is supplied to the motors 31 in any suitable fashion. That shown comprises the slip rings 50 suitably insulated and mounted on the upper portion of the rotary frame member, and brushes 51 arranged to cooperate therewith and mounted in the cover plate 6. From the collector rings 50, the wires 4.4 lead down to the arms 25, and out through the casing portions 42 to the motors.

In the shaft 34 is arranged a suitable escapement clutch 52 of any suitable form such as will permit the shaft being uncoupled at will to disconnect the revolving mechanism from the motor, and such as will be operable by excessive pressure to permit escapement in case the revolving portions should meet with an obstruction. Or a suitable clutch 43 may be placed in sleeve 39.

By virtue of the mechanism above described, it will be observed that'the revoluble movement of the fans is derived positively from the fan motor, and may be regulated as to speed by regulation of the speed of the fan motor. Furthermore, it is to be observed that the fans are adjustable independently to various angles, without adecting in any fashion the operation of the rotating mechanism. A neat, compact and substantially dust-proof mechanism is provided, and thorough lubrication of the working parts is secured. Suitable mounting. for the switch 17 and the speed controlling coil 54 is provided. The latch pins 31 are operable from the exterior of the casing, so that no dismantling of the device is required in order to adjust the fans.

I am aware that my invention is suscepti ble of changes, modifications, and adaptations not herein specifically described or shown, but comprehended nevertheless within the scope and spirit of my invention as indicated in the following claims.
