AUTOMOBILE FAN DEVICE.
application filed August 31, 1922. Serial no. seassv.
to rovide an electric fan device which is designed to permit of it being mounted within the top of an automobile, between the upper wall and the lower wall, with a cover P ate extending only a slight distance outwardly beyond the ower wall, which is ordinarily the upholstery of the. top.
A further object of the invention is to provide a device of the above mentioned character, embodying a frame construction which not only serves to hold and support the operating parts of the motor, but also serves to connect with the lower wall or upholstery of the top.
A further object of the invention is to provide a device of the above mentioned character, so designed that its thickness is reduced to the minimum, so that its lower end maybe substantially flush with, or project only a slight distance below the lower wall of the top.
A further object of the invention is to provide a device of the above mentioned character, so constructed that parts thereof may be readily removed, so that access may be had to the interior of the device, without the removal of the main supporting frame.
A further object of the invention is to provide a device of the above mentioned character, which is simple in construction, strong, durable, and neat and attractive in ap earanoe.
ther objects and advantages of the invention will be apparent durmg the coum of the followin." description.
In the accompanying drawings formin a part of this specification, and in whichllke numerals are employed to designate like parts through the same,
Figure 1 is a central vertical sectional view through a fan device embodyingmy invention, and,
Figure 2 is a perspective view of the frame elements separated.
In the drawings, wherein for the purpose of illustration is hown a preferred embodi ment of my invention, the numeral 5 designates a main sup orting frame or member, as a whole, em ying a late or base 6, having PIO]8C1;1ODS or cars for the recep tion of screws 8 or the like, adapted to engage with the top wall 9 of the automobile top. Preferably formed integral with the base 6 and depending therefrom are spaced legs 10, provided at their lower ends with outwardly projectin cars 11, as shown.
The numeral 12 esignates a spider, as a whole, embodying a hub 13, car ing radial arms 14, secured to a rin 15. il'he spider is preferably an integra structure. The
ring 15 has openings 16 formed therein to receive the screws 17 engaging in screw threaded openings 18, formed in the inner ends of the ears 11.
Mounted within the supporting frame5 and held stationary thereln by an suitable means, are the field windings 19 o a motor. The numeral 20 designates the armature, carried'by the armature shaft 21, provided with the usual commutator 22, engaging the brushes 23.
The n per end of the armature shaft 21 is rotata le in a bearing 23', formed in the base or'plate 6, while the lower portion of the armature shaft 21 has a thrust bearing ring 24 rigidly mounted thereon, and provided with a race way 25, receiving balls 26, operating within a race way 27, formed in the hub 13, which is the coacting thrust element of the thrust bearing. This bearing not only takes the downward thrust but also takes the radial thrust.
The armature shaft 21 projects downwardly for a short distance below the thrust bearing and has a fan 28 mounted u 11 its lower end. This fan is preferably etachably rigidly mounted upon the armature shaft, by any suitableimeans, such as a set screw or the like. f o
The fan 28 is protected by a cover or dome 29, which may be formed of pressed or stamped sheet metal, of suitable ornamentation, and having suitable openings 30 for the free passage ofthe air from the fan. The cover 29 is curved in cross section ad'acent to its periphery and carries at this mt an annular flange 31, which is aperture for receiving machine screws 32, which engage in screw threaded openings 33, formed in the ring 15 and cars 11, as shown.
The supporting frame 5 is relatively thin, and is designed to be mounted entirely within the air space occurring in the top construction of closed cars, such as the sedan or coup. In the drawings, the numeral 34 represents this space and 35 the lower wall of the top structure, which is ordinarily upholstery, such as cloth, leather or the like. The upholstery 35 has a circular opening cut therein, and the edges of this opening are passed between the flange 31 and the rin 15, and these parts are clamped to get er' by screws 32. In this manner the upholstery is connected wlth a ring 31 and a neat and attractive union is secured. The cover or dome 29 projects downwardly only a slight distance beyond the upholstery 33.
Should it be desired to gain access to the commutator 22, the cap 29 is first removed, and the screws 17 are removed, and the spider 12 would then be moved downwardly,
carrying with it the armature shaft and associated elements. The fan may now be removed from the lower end of the armature shaft, and the spider removed from the armature shaft, thereby afiording free access to the commutator and brushes.
The supporting frame 16 is open on all sides, by virtue of the spacing of the legs 10, and the spider 12 also has large segmental openings, and the air may be drawn over the fan from the space 32, and discharged into the'car. Further, these spaces afi'ord means for access to the commutator and other parts, in making minor re mm.
It is to be understood that t e form of my invention herewith shown and described is to be taken as .a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the Spll'lfi of my invention or the scope of the subjoined claims.
