Application'J uly 23, 1942, S erialt No. 452,012 I 4 Claims. (01. 230-1117) 1 *invention relates to a blower housing and the combination ofjthe housing and a'motor having wideaDPliCatiOnaIthough intended primarily for blowing 'coolingair over the tubes of a radio receiver or transmitter. Thebloweris driven by a smallmotor of which there are a great many style and different dimensions, the housing is constructed so that it is easily adapted to receive any style of motorgwith their widely differing bases or attaching means. I I v 'It' isfan objectiof the invention -toconstruct a blower housing'which is adapted to mount any style of. small motor which drives'the impeller within the blower housing.

Another object of the invention is to construct a blower housing which is adapted to bemoii'nted in a. great. many different positions thereby permitting the greatest degree of latitude inth'positibnin which the housing. may be; mounted when Putin use I "'A still further object "is t6 eons tructamowr housingand motor assembly which affords a wide variety of ways in which a motor and the housing may be. secured together and may be secured to some supporting structure.

Other objects of the invention will'be more apparent from the following description taken in connection with the accompanying drawing illustrating a preferred embodiment thereof, in

which: c

Figure 1' is a side elevation of the blower housing. I

Figure 2 is an elevation of the housing with a bracket for securing the same to a supporting structure.

Figure 3' is a View of a flatplate forming one side of the housing to which a motor has been secured. The motor is shown attached to any suitable structure such as the wall of a radio chassis. v

- Figure 4 shows a blower housing with a motor secured thereto in anothermanner and the assembly mounted upon a. wall or other supporting structure.

Many radio sets require a cooling stream of air to be. blown into the cabinet so that it will circulate over the tubes and to dispel the heated air from within the chassis or case. Such a blower must be capable of being mounted within the chassis in a great variety of ways. Again, a parblowerhousing must be capable of receiving any style offm'ctor. 1 f v l e blower housing has a body portion which preferably is of plastic or'molded .materiaLi A molded. housing is split through the center thereof .to'fo'rm body sections I0 and II. The body portion or particularly body section III has a side wall in {whichthere -.i an air inlet opening not shown. The twosections of. the body when. assembled have an outlet opening I2 which directs a stream of air from the blowerv housingin the direction desired. i

The body or particularly the body section I I- has an .open side through whichthe blowerimpeller is insertedwithin the housing. 3 The open sideis covered by a plateIE whichis preferably flat, so that it may be easily. drilled to receive" screws ,IB which secure the motor IT to the plate. and-house ing. ,Screw'holesmay be drilled anywhere in the plate thereby adapting the blower housing to be driven by a motor haying any style of base or se-v curing means. I'Il'iefplate has a hole I8 through which the motor shaft I9 projects .and the blower impeller is secured to the motor shaft.

The flat plate is secured to the housing by screws 2|. These screws also secure the two halves of the housing together by having threaded nuts embedded or molded into the body section I0 and screw holes are then provided in the body section II in alignment with the nuts. The screws 2I therefore secure the flat plate and the body sections II and I2 together to form the complete housing. The screws 2| .have a varied spacing with respect to each other and also with respect to the motor shaft opening I8 thereby rendering the screws available for a wide variety of mountings for the housing and motor.

In Figures 1 and 2 a bracket 22 may be secured to the housing byone or more of the screws 2| and the bracket in turn is anchored to some part of a, radio chassis or other piece of mechanism upon which the blower is'to be mounted. The motor H, in beingsecured to the plate I5, and

the blower are therefore mounted as a unit in position by the bracket 22.

Figures 3 and 4 each illustrate another way in which the motor and blower may be mounted and suggest the many other ways in which the combination of motor and blower may be secured together and the assembly may be secured to any supporting structure. In Figure 3 the motor is secured to the plate I5 and the plate I5 carries the body portion of the blower housing. The motor, however,'carries a bracket 24 which is secured to the motor by screws 25 which utilize the securing means or screw holes already provided with this style of motor. The bracket 24 is in turn secured to a wall W by a screw 26 to mount the motor and blower in a desired position.

In Figure 4, still another style of mounting is illustrated for a motor 28 having a different style of base or securing means. This style of motor ha s curing means in the periphery thereof, and cons quently requires a bracket 29 which is secure to the motor by screws 30. One end of the bracket may besecured to the blower housing by one of the screws 2| and the other end of the 2. A blower housing comprising a body portion formed of sections and with a completely open bracket may be secured to a supporting structure such as a chassis wall W by screw 3|.

The three embodiments of mountings illustrated are merely indicative of the wide adaptability of the blower housing to receiveany style of motor and having any style'of base or securing means. The drawings also illustrate a wide variety of ways in which the motor and blower assembly can be mounted in any desired position wherever used such as in a radio chassis.

This invention provide an improvement inv a blower housing and assembly. It is understood that various modifications in structure, as well as changes in mode of operation, assembly, and manner of use, may and often'do occur to those skilled in the art,.especially after benefiting from the teaching of an invention. This'disclosure illustrates the preferredmeans of embodying the invention in useful form.
