Application July '8, 1939, Serial No. 283,412
for quickly and conveniently drying polishes applied thereto.
Animportant object of my invention is the provision of a relatively inexpensive, compact and portable finger nail drying device which is provided with air propulsion means and heating means in a separate compartment whereby the heated air will be drawn from areas adjacent to the heating elements away from the persons hand and be expelled on the opposite side of the device.
A further object of my invention is the provision of a portable finger nail polish drying device consisting principally of two separate sections and compartments, one thereof being openable for the convenient positioning of the users hand and. also containing suitable heating units such as lamp sockets, and the other compartment communicating with said heating compartment containing a suitable electric motor and propeller adapted to draw the heated and dry air from the area about said heating elements over and in contact with the finger nails and to then expell same on the opposite sides of the device.
A further object of my invention is the provision of a portable device fordrying finger nails adapted for use in beauty shops and the like which in addition to including air propulsion means, includes a hingedly mounted hood having a large opening at one end and which has mounted in the adjacent inside upper surfaces thereof suitable electrical heating elements, which is hinged with respect to the base of the device and when open permits convenient positioning of the users hand and which when closed permits the air to be drawn in at the end opening of the hood, heated by said heating elements and passed over the ends of the users fingers and drawn into and expelled from the adjacent motor compartment.
Other and further important objects of my invention will be apparent from the following de-.
scription and claims. 7
This invention (in preferred form) is illustrated in the following description.
Fig. 'l is a side elevational view of my finger nail drying device with the hood upraised and showing both the lamp heating elements and'a portion of the users hand in normal operative position.
Fig. 2 is a cross section view taken on a horizontal plane with the hood in closed position and showing the internal parts.
Fig. 3 is a vertical cross section view of the de-' vice taken on line 33 of Fig. 2, except showing the users hand and blocks in side elevation.
Referring to the drawings, reference numeral l 0 designates a suitable base which may be made of metal, plastic, or equivalent material and which is preferably defined at one end by the arcuate edge [0a and at its other end preferably by a straight end edge IOb as illustrated in Fig. 2. Reference numeral H designated a hood which may be of metal, plastic or other suitable material and which is of substantially semi cylindrical cross section, being defined by the substantially semi-circular wall Ila which is preferably slightly inclined outwardly at its lower end as indicated in Figs. 1 and 3, and by a vertically extending metal partition wall Ilb whose opposite flanged ends are secured by suitable rivets l2 or equivalent fastening elements to the vertically extending side wall Ila as indicated in Fig. 2. The top portion He is formed substantially flat and integral with the arcuate wall II a as clearly shown in Fig. 3 and is provided with a plurality of spaced apart struck out integral projections l3 which are adapted to retain a suitable finger bowl upon the device for convenient use of the user. A plurality of spaced apart apertures are formed in the end portion of the arcuate wall Ila and which form air exhaust ports I 4, as clearly shown in Figs. 2 and 3.
The transversely extending partition wall Ilb is provided with relatively large substantially central apertures I5 which forms the communication between the compartment formed by the hood H and the heating compartment. This opening or aperture I5 is provided with a suitable screen l6 which is secured by means of an annular valve ring I l which metal ring is in turn secured to the partition wall Ilb by suitable threaded screws l8. This screen serves as a guard against accidental insertion of the users fingers.
Secured by a pair of bolts I9 which pass through apertures on the opposite sides of aperture l5 are a pair of substantially Z shaped angular metal brackets 2| having opposite apertured ends projecting towards each other and upon which a suitable electric motor 20 is mounted in substantially the position illustrated in the drawings. Screws 22 connect said angular brackets 2| and the said electric motor. The electric motor includes the shaft 20a, the end of which projects as illustrated and which shaft has suitably mounted upon it a propeller 23 which 7 is adapted to draw the air through the inlet port l4. Numeral 24 designates a negative and positive wiring of conventional form including the negative and positive wire connected to the inner and outer poles of the electric motor 20, and which wiring circuit is controllable by suitable control switch 26 which is mounted in a suitable aperture in the upper wall I I c of the metal housmg.
I will now proceed to describe the hingedly mounted hood designated generally by the reference numeral 2'! which includes the substantially fiat integral top portion, the vertical end Wall 2111 provided with a relatively wide and large aperture 21b, and including the vertically extend-v ing opposite side walls 210 all of which are formed as a single stamping or molded unit. As indicated in Fig. 1 the side wall 210 has a pair of hinges 28 secured thereto whereby said hood is hingedly connected to the base 10 adjacent one edge thereof, the same being shown in open position in Fig. 1. The opening 21b is of a size sufiiciently large to permit insertion and withdrawal of the average users hand and to permit entry of air between the arm and the hood.
The mounting means for the heating elements consist of a pair of substantially right angled brackets 29 which are secured on the adjacent. inside surface to the top of the hinged hood 2'! by means of pairs of screws 30 which thread into suitable threaded apertures in the hood 2"! as clearly indicated in- Fig. 3. The projecting portions of the brackets 29, which are preferably two in number, are suitably apertured and have. secured thereto sockets 3| respectively into which. heating type electric globes 32 are removably mounted. The position of said electrical heating globes 32 is such that they lie in the upper portion of the hood and are not subject toaccidental contact of the users hand. The sockets 3| and globes 32 are electrically joined through suitable wiring 33,v only a fragment of which is shown, and which wiring is connected in circuit with the wiring leading to the electric motor, as indicated at. 34 of Fig. 1,. The control switch 26 thereby starts; and stops the electric motor and simultaneously lights and extinguishes the: heating lamps or globes 32,.
Numeral 35 designates aremovable block forming a convenient hand rest and which is pref-- erably formed of material of low heating conductivity and which is also provided with a plurality of spaced apart grooves 35a which are so positioned as to conveniently receive the spread apart fingers of the users hand. This block also aids in positioning the ends of the fingers and:
finger nails in a position where a substantial part of the heated air drawn into the inlet opening l of partition wall [lb will pass over and contact. the finger nails and portion thereon to dry and bake the polish applied to the nails.
Reference numeral 36 designates an inner heat reflecting metal wall of substantially U-shaped cross section, the sides of which are secured ad-v invention is the fact that the combination structural features with the hingedly mounted hood and other parts causes the air to be drawn in and from the room at points through the aperture 21b and surrounding the users hand and circulated about and in contact with the heating globes 32, and passed about and in contact with the finger nails of the users hand before being drawn through the exhaust port I5 by the propeller 22 and outwardly through the exhaust port M. This prevents heated air from being blown against the person using the machine as is the case with drying units such as used for the hair etc. Use of my device keeps the user comfortable and shortens the period of drying and baking the polish on the finger nails to an average of about two minutes, as distinguished from presently known drying periods ranging from 15 minutes and upward.
It has been the common experience of beauty shop operators that the drying of finger nail polish by merely allowing the customers to wait during normal time requires the customer to remain in the shop for unnecessary periods of time, and clogging operation upon busy days. It. is well; known that getting the respective operations completed with quickness as well as with satisfaction saves time both for the customer, beauty operator and shop owner, and permits more customers to be handled by any particular shop facilities in a, given time. Experience has found that use of hood type hair dryers for drying the finger nail polish not only Wastes considerable time but creates discomfort and dissatisfaction, and my invention has eliminated these various objectionable,- features' as well as provided a means for insuring that the polish will be sufficiently dry or baked upon the finger nail before the patron leaves the shop, it being well known that: beauty shop patrons frequently use their handstoo soon and before the polish is properly dried after which they complain that the polishing job was unsatisfactorily performed.
I am aware that numerous details of the construction. of my invention may be varied without departing from the principle of my invention, and I. do not desire to have my invention limited to the, illustrations herein shown and described.
