Applicaflonflled August 28, 1922. SeriaLNo. 584,751.
To all whom it may concern:
Be it known that I,-JoH1\ J. Mum, a
citizen of the United States, residing at 600 dr W. Erie Street, Chicago, in the county of Cook and State ofIllinois, have invented be certain new and useful Improvements in Drying Apparatus; and I do hereby declare the following to be a full, clear, and
exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This'invention relates to improvements in drying apparatus and has for its principal object the provision of a simple and efiicient means for drying the hands and face or the hair of a person in a sanitary and rapid manner, and which can also be used for other purposes, and particularlyfor drying articles of glassware, dishes and thelike.
One of the important objects of this invention is the provision of an air drying apparatus which shall be compact and efficient, and which is composed of a minimum of parts, and therefore not likely to get out of order.
Another important object of thls invention is the provision of an electrically operated air drying apparatus, provided for the ready delivery of a blast of instantaneously heated air, and which consists of a plurality of electrically heated coils or resistance element over which a current of air is drawn or forced by means of an electrically operated fan or the like.
Still another important object of this invention is the provision of an electrically operated drying apparatus'provided for the instantaneous delivery of a blast of heated air which shall be so constructed and mounted that it is capable of being adjusted universally in any direction, and which therefore can be conveniently used in connection with ractically any article from which it is desired that moisture may be evaporated.
A still further object of this invention is A further important object of the invention is the provision, in an electrical air ying apparatus, of suitable resistance coils over which the current of air is ada ted to drawn or forced, and thereby eated, which resistance coils are constructed in combination with a series of baflie plates or the like, so that the air which is drawn or forced over the coils will be compelled to follow a circuitous path, and thereby the ful(l1 heating efficiency of the coils be util- 1ze Other and further important objects of theinvention will be apparent from the disclosures in the accompanying drawings and following specification.
The invention, in a preferred form, is illustrated in the drawings, and hereinafter more fully described.
In the. drawings:
Fig. 1 is a vertical sectional view of the improved air dryer of this invention.
Fig. 2 is a sectional view taken on the curved line 2-2 of Fig. 1, looking in the direction indicated by the arrows.
Fig. 3 is a detail vertical sectional view of one of the removable heating nozzles of this invention, shown enlarged.
Fig. 4 is an end view of the'nozzle looking at the same from the delivery end.
Fig. 5 is a vertical view, partly in section, :howmg a slight modification of the invenion.
As shown in the drawings:
The reference numeral 10 indicates a base or stand upon which the improved air drymg means of this invention is mounted, and 12 shows the outer shell of a ball and socket joint of well known construction, having a spherical member 14 operating therein, which spherical member 14 forms an integral portion of the casing 16 of the device, the shape and construction of which obviously may be varied as desired.
The casing 16 is made in two parts, as shown, and is held together by screws or bolts 18 or the like, and a central frame is positioned in the casing, as shown at 20, having a motor '22 mounted therein by means of screws 24 or. the like.
The motor 22 is provided with the usual shaft, upon the end of which is mounted a series of fan blades'26 or the like@ A circular bafile plate 28' is positioned in the casing 16 in front of the fan 26, and is provided with a series of holes or openings 30 at the outer circumference thereof, as
shownin both the figures, in order to deflect the entering current of air to the outer ed s of the device, as shown by the arrows.
emovably positioned in both the front and rear of the casing are nozzles 34, as
shown, each of said nozzles having mounted therein a number of resistance elements or heatmg coils 36, as shown, over which a current of air is adapted to be drawn or forced by the fan blades 26. 'Mounted in conjunction with the resistance coils 36 is a series of metallic baflie plates 38, which have their dished peripheral edges alternately straight and curved, as shown, and adapted for deflecting the current of air as it flows through the nozzles 34, and thereby causing same to follow a circuitous path around the baflle plates 38, and in that manner insuring a more thorough contact of the air with the heating coils or resistance elements 36, and a consequent better heating ofthe same in a shorter space of time, and with a minimum amount of heating surface. As illustrated, the curved and straight bafile plates are fastened together, the curved plates being attached to theinterior of the nozzles.
As will be noted, binding posts 40 are provided upon each of the nozzles 34, whereby electrical connections 42 may be readily applied thereto, and the wires 42 to the heating means are connected in parallel with a" having a shaft extending into the casing upon which the fan blades 26 are mounted. This modification is rovided for use with motors which are liale to become heated in operation, and which would be particularly liable to occur in the construction shown in Fig. 1, wherein a blast of hot air is being continuously passed over and through the motor. In the construction shown in Fi 5 this difii'culty is eliminated by having t e intake nozzle 34 positioned at the upper rear edge of the casing, as shown, immediately above the motor, or
in any other convenient location as desired.
A plurality of such intake nozzles 34 may Y also be provided if necessary. It will be obvious that the intake nozzle may be omitted entirely from the construction, and
openings simply placed therein, provided sufficient heat is delivered by the air passing over 'the heating elements in the delivery nozzle.
The current having-been switched on to the motor, which switch also supplies current to the heating coils 36, immediately propels the fan blades 36, thereby drawing a current of air into one of the nozzles 34 over the coils 36 in said nozzle 34,- which coils are heated by the current, and in conjunction with the dished bafiie plates'38 in the nozzle, a maximum heating of the air is attained, the construction of the baffle plates being such that the air in passin through the nozzle 34 is constrained to fo ow a 01rcuitous course, as will be evident. The air havingbeen passed through the casing by means of the fan blades or pump 26, is now deflected downwardly, as shown by the arrows, and impelled out through the delivery nozzle 34, which also contains a series of heating coils 36 and baffle plates 38, whereby the air is additionall and fully heated. The heated air thus disc arged may be used for-practically any drying or similar purpose, as has heretofore" been pointed out: The universal mounting of the device provides an additional advantage, which will be readily apparent.
I am aware that many changes may be made, and numerous details of construction varied throughout a wide range, without departing from the principles of this inven-'.
tion, andI therefore do not-purpose limiting the invention otherwise than as necessitated by the prior art.
I claim as my invention: 1. In an air-blast drying apparatus, the
. combination with acasing, a ball and socket mounting therefor, a motor suspended in said casing, fan-blades rotatably carried, by said motor, a baffle plate in juxtaposition with the fan-blades, aligned inlet and-outlet nozzles carriedby said casing at opposite sides thereof, and heating elements positioned in said nozzle.
2. In an air-blast drying apparatus, the combination with a casing, a ball and socket mounting therefor, a motor suspended in said casing, fan-blades carried by said motor, a perforated ba-flle plate in juxtaposition with the fanblades, aligned removable nozzles attached to said casing, heating elements in said nozzles, and a plurality of baflles in said nozzles.
3. In an air-blast drying apparatus, the combination with a casing, a ball and socket mounting therefor, a motor suspended in said casing, fan-blades carried by said motor, a perforated baflle plate in juxtaposition with the fan-blades, align ed removable nozzles carried at the opposite sides of said casing, heatin elements in said nozzles, and a plurality o dished baflies alternate ones of which extend to the inner walls of said nozzles and are provided with centrally disposed openings.
4. In an air-blast drying ap aratus, the combination with a casing, ai-ball and socket which extend to the inner walls of said nozz'les and are provided with centrally d1sposed openings, and heating elements interposed between said baifles.
