FINGER DRYING DEVICE Filed Dec. 12, 1956 1 5 1 gab-.2. 2* O ATTORNEYS Patented Aug. 17, 1937 UNITED STATES PATENT OFFICE 7 Claims.

My invention relates to a new and improved device for drying finger nails.

One oi the objects of the invention is to provide a simple device which includes a heater and a blower, whereby a nail lacquer or other liquid or wet toilet preparation can be rapidly dried, after said lacquer or the like has been applied to the nails.

Another object of the invention is to provide a simple and inexpensive and convenient device for said purpose.

Another object of the invention is to provide a device having an electric motor and an electric heater, the circuit of said motor and said heater being controlled by a hand-operated switch, so that the pressure of the hand can close the circuit of the motor and of the heater, while the fingers of said hand are located in the path of the current of heated air.

Other objects of my invention will be set forth in the following description and drawing, it being understood that the above statement of the objects of my invention is intended generally to explain the same without limiting it in any manner.

Fig. 1 is a front elevation showing the improved device.

Fig. 2 is a side elevation, partially in section.

Fig. 3 is a rear elevation of the device shown 3 in Fig. 1, partially in section, the representation of part of the device having been broken away in order to illustrate the parts more clearly.

Fig. 4 is a bottom plan view on the line 4-4 of Fig. 3, part of the device having been removed 85 so as to illustrate the other parts more clearly.

Fig. 5 is a sectional view, partially in elevation, on the line 5-5 of Fig. 2.

Fig. 6 is a sectional view on the line 66 of Fig. 3.

Fig. 7 is a detail plan view, which diagrammatically shows the heating coil and the connections thereto.

The housing of the device comprises superposed metal shells 2a, I, and Id, which are suitably 45 connected to each other, by means of soldering or the like.

As shown in Fig. 3, the bottom shell 2a encloses a base 2, which has integral depending feet 3, so that the device can be mounted upon a table 50 or other suitable support, with the bottom shell 2a spaced from said support.

The device is also provided with an electric motor for operating a blower. Said motor includes the usual laminated field, which is made 55 of a plurality of metal rings I1. The rings I1 are connected to the top horizontal flange of the shell I, by means of vertical screws. Nuts are mounted at the bottom ends of said vertical screws so as to clamp the metal rings IT and the shell 2a, to the shell I.

As shown in Fig. 3, the shell 2a has a horizontal flange which extends inwardly of the vertical face of the shell I, and said vertical screws pass through the horizontal flange of the shell 2a. The base member 2 can have a tight flt between the rings I1 and the vertical face of the shell 2a, so that the base member 2 is clamped in position.

The base member 2 can be connected to the shell 2a in any suitable manner.

For convenience the device is described with reference to the vertical position which is illustrated in the drawing although it can be used in any other position.

The shell Id can be connected to the shell I by soldering or in any suitable manner.

The electric motor is provided with the usual field coils, which are wound around inner extensions of the metal rings I1, and it is also provided with the usual armature M. The shaft I4 of the armature of the motor is mounted in a bearing member I2, which is connected to one or more of the rings IT, by means of screws or other suitable connecting devices, which pass through the holes H which are shown in Fig. 4.

A blower having blades I5 is fixed to the upper end of the shaft l4, above the horizontal flange of the shell I. Since the horizontal flange of the shell i is perforated, the blower will operate to force a current of air upwardly through the shells 2a, I, and I'd.

As shown in Fig. 3, the shell Id is provided with a horizontal flange, which is provided with an integral and upstanding ring 20a.

As shown in Fig. *7, a series of heating coils 2| are connected to bus- bars 20 and 23, which are held spaced from the metal ring 20a, by means of an intermediate ring 2d, which is made of any suitable insulating material. The bus- bars 20 and 23 are suitably connected to the supporting ring 20:! by any suitable means which will prevent electrical contact between said bus-bars and said supporting ring 20a.

A metal screen S is connected to the ring 20a above the heating coils 2|. The shell Id is provided with vertical extensions I0, and said extensions are of substantially rectangular cross section. Said extensions are connected by. a tapered web Ia, which has a general conical shape, so that the upwardly moving air current is forced through a relatively narrow and substantially rectangular slot which is provided for this purpose at the top of the shell id.

A pan 6 is connected to the top of the shell Id, to serve as a finger rest. Said pan has a slot In, which has substantially the same shape as the air-outlet slot which is provided in the top of the casing Id, and the walls of said slots are connected to each other, so that all the air is blown upwardly through the slot Ill, so as to 10 contact with the fingers of the user.

The pan 6 is provided with an extension 7.

Referring to Fig. 2, a hollow member 8, which operates the control switch of the device, is tumably connected to the extension I by means of rods 9.

As shown in Fig. 6, the rods 9 are integral with a lateral rod 30. Fig. 5 shows a bearing sleeve 32a, in which the rod 30 is turnably located, and said bearing sleeve 32a is suitably connected to the pan 6.

As shown in Fig. 6, the metal rod 30 is provided intermediate its ends, with an upstanding portion which can contact with an insulating member 21, made of asbestos or other suitable material, which lines a curved portion of the resilient switch blade 26. Said resilient switch blade 26 is made of any suitable metal and one end thereof is fixed to the contact 25, which is connected to a suitable insulating support, which is fixed 30 to the pan 6.

The member 26 is the control switch of the device and it closes the circuit when it touches the contact 28, which is also mounted upon a suitable insulating support, which is fixed to the member 6.

Springs 33 are connected to the rods Q and to the inner wall of the member i, and said springs normally hold the rods 9 in the position illustrated in Fig. 6, in which the switch 26 is held in the circuit-opening position. However, by rocking the member 8 and the rods 9 from the full line position indicated in Fig. 2, to the broken line position indicated in said figure, the rod 30 is also turned so that its upward extension is turned sufficiently to permit the resilient switch blade 26, to touch the contact 28.

The sleeve 32a may be provided with extension lugs 32, which are connected to the pan 6 by screws or the like. The heating coils 2! are connected in parallel to the motor circuit so that the supply of electric current to the motor and also to said heating coils is controlled by the switch 26.

The electric current, either alternating or direct, is supplied through the line wires Ca and Cb, which form part of a cable C which is provided with the usual plug P. The line wire Ca is directly connected to the bus-bar 20, and to one of the terminals of the electric motor. The

line wire Cb has two separated sections. The

section which is connected to the plug P is connected to bus-bar 23 and to contact 28. The other section has one end thereof connected to contact 25, and the other end thereof connected to the second terminal of the motor. Hence the circuit of the coils and motor is controlled by switch 26.

The motor can be of any conventional type and since the connection of a heating coil in parallel with the motor is well known per se, the details thereof are not shown in the drawing.

When the device is operated, the user rests the palm of her hand upon the member 8 and pushes the same downwardly until the finger nails of the user are directly above the slot IU of the pan 6.

The movement of hand-rest 8 turns rods 9 and the rod or shaft 30, so that switch 26 can close. the circuit.

An ascending current of heat or air is therefore provided which rapidly dries the lacquer or other wet toilet preparation which has been applied to the finger nails of the user.

The device is extremely simple and compact and the use thereof is extremely convenient.

I have shown a preferred embodiment of my invention, but it is clear that numerous changes and omissions can be made without departing from its spirit.
