unit and universally adjustable electrical mounting thereof.
The primary object of the invention is the provision of a structure of this character, wherein the fan and motor unit has a universally adjustable electrical separable plug adapted to fit an electric service socket, so that the unit can be operated by electric current and may be adjusted to any selected position through the plug for directing air supply from the unit in any desirable direction, the structure being novel in its make up andis unique in the arrangement of the parts thereof.
Another object of the invention is the provision of a structure of this character, wherei the hub portion of the bladed fan wheel is rendered elastic, so that it can be applied firmly to a rotor for the drive shaft of the motor,- the hub portion being telescoped over the rotor with snug fitting thereon, the motor casing and the hub portion of the wheel having reversely tapered formations, thus giving to the unit a stream-line-set up.
A further object of the invention is the provision of a structure of this character, wherein the assembly of-the same is novel in its entirety, and is possessed of few parts, these being readily accessible, thus economical for repairs and replacemerits.
A still further object of the invention is the provision of a structure of this character, which is simple in construction. thoroughly reliabie and enicient in operation, s ong, durable, readily and easily adjusted with dispatch, neat in appearance, and inexpensive to manufacture and install.
With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the -1 Claim. (Cl. 230-273) electric motor assembly l2 provided with a driving shaft l3, centrally located and extending i'orwardly from the casing. This shaft it has a for ward nut carrying tip I4 to which is fastened by the nuts it a substantially cone-shaped rotor Hi, the forward end ll of which is closed, excepting a clearance :tor the tip !4, while the innermost end i 8 is fully open.
The shell ii at its outermost small end has built therewith an externally threaded annular nipple 59, providing interiorly thereof a ball seat or socket 20, the nipple threads being indicated at El, and detachably connected tothis nipple it is a coupling collar 22 for a transversely split two-part ball joint forming a universal knuckle head 23, for socketing in the seat or socket iii, the parts 24 and 25, respectively, being held together for separation, and retained in the socket 20 by the collar 22, as is best seen in Figure 2 of the drawing,
The shell H is movably keyed at 25 to the part 24, which has assembled therewith the electric current wires 21 leading from spring finger contacts 28 to the motor l2, the contacts 28 being mounted on the part 24 and are adapted for separableengagement with companion spring contacts 29 socket-ed in the part 25, which latter -has unitary therewith an extension plug to,
preferred embodiment of the invention, and
pointed out in the claim hereunto appended.
In the accompanying drawing:
Figure l is a side elevation of the structure in accordance with the invention;
Figure 2 is a view similar to Figure l, and on an enlarged scale, partly broken away.
Similar reference characters indicate corresponding parts throughout the several views in the drawing.
Referring to the drawing in detail, the structure constituting the present invention, comprises a motor casing 10 which has its rearmost shell Ii outwardly tapered, and within this casing is an adapted to be threaded into an ordinary light socket fitting St for electrical connection of the motor'leacls to an electric current supply or current source of a wiring system, not shown.
On the rotor it is engaged through telescopic fitting thereover is the elastic hub portion of a bladed fan wheel, the blades of the same being radially extended from this hub portion and angled to the axis of the wheel, as is usual, for air circulation. The hub portion 3?! is correspondingly shaped to the rotor and at its open inner end is provided with an inturned annular flange 34 which overlaps the open end iii of such rotor for the securing of the portion 32 thereon, as is clearly shown in Figure 2 of the drawing, while the outer end 35 of this portion 32 is closed to conceal the fastening of the rotor on the motor shaft.
It will be apparent that the knuckle head 23 permits the fan casing ill to be adjusted with ease and dispatch, and this adjustment can be held by tightening the collar 22 on the nipple is.
It is of course understood that changes, variations and modifications may be made in the invention as fall properly within the scope of the appended claim, without departing from the bly ball Joint socket, and means detachably nt- 15 2,312,627
