SHOE DRYING ATTACHMENT Filed Feb. 1'7, 1936 JOSEPH P- L'E/A DORF INVENTOR.
ATTORNEY.
Patented Apr. 13, 1937 UNITED STATES PATENT OFFICE I 3 Claims.
This invention relates to a shoe drying attachment for electric hot air blowers.
An object of this invention is to provide means whereby heated air from an electric air blower 5 and heater enters a tubular guide nozzle havin a flared outlet which is designed to permit reversal in direction of air flow into the shoe and so that the air may freely leave the shoe while the drying operation is being performed.
Another object of this invention is to provide a nozzle having a flared and constricted or flattened outlet defined by upper and lower walls, the lower w-all extending at an angle with the apex directed centrally outward, and the upper 15 wall being curved all along its length into the tubular nozzle and forming a channel which permits outward flow of the hot air entering the shoe through said nozzle.
Another object of this invention is to provide 20 a portable nozzle attachment of the character described which may be used for drying shoes while resting on a floor in normally upright position.
With the above and other objects in view, the D invention will be hereinafter more particularly described in connection with the accompanying drawings and pointed out in the claims which form part of this specification. 1
Reference will now be had to the drawing, 9 wherein like numerals of reference designate corresponding parts throughout the several views, in which:
Figure l is a side elevation of the drying attachment in operative position in a shoe.
Figure 2 is a central longitudinal cross-sectional view of the attachment.
Figure 3 is a perspective view of the attachment.
Figure 4 is a cross-sectional view of the inlet portion of the attachment, the section being taken as on line 44 in Figure 2.
In the illustrated embodiment of the invention, the numeral l0 indicates an electric air-blower of the portable type, having a handle I l by which it is gripped. The blower It] comprises a motor and a fan which sucks air through an inlet l2 and discharges it into an outlet IS. The motor casing carries a resistance or heating element (not shown) as is well known in the art.
- A shoe-drying attachment or nozzle [4 has been secured to the outlet [3, preferably in frictional engagement. The attachment or nozzle [4 has a curved tubular body l5 substantially in the form of a right-angle. As shown in Figure 3, the nozzle M has a flaring and constricted outlet I6 defined by an upper wall I! and a lower wall l8 which are slightly spaced apart, the lower wall I8 being angularly directed and extending outwardly more than the upper wall, as shown in Figure 3. The nozzle has a tubular inlet I9,- having a cross-section corresponding to the crosssection of the outlet l3 from the blower.
The upper wall ll of "the outlet [6 has a central concave portion 20 and this concavity extends all the way from the lower end 2| of the wall l-l up to the inlet 19 of the nozzle. This concave portion forms a channel which permits outward flow of air entering the shoe 22 through the nozzle I4.
The apex 23 of the angularly directed wall l8 has been curved upwardly to face the channel 20, so as to aid in reversing the direction of flow of the air from the downward direction inside the nozzle into an upward direction into the channel 29 outside the nozzle.
The cross-section of the inlet into the attachment may be varied to suit different crosssections of outlets from existing air blowers, or the attachment may be made to form an integral part of an electric air blower.
The flared or outwardly widened and con stricted outlet ll serves the purpose of increasing the force with which the hot air from the electric air blower strikes the tip of the wet shoe and carries out the evaporated matter more rapidly.
The normal foot causes a minimum temperature of 90 F. in a shoe. When walking outdoors during cold weather, the air inside the shoe is excessively warm and as the cold air strikes the shoe from the outside the evaporation from the foot is liquefied, and the shoe becomes wet and causes bromidrosis. The bacteria responsible for this condition may survive in the damp shoe and cause further complications.
The tip of a shoe is the wettest portion. It practically impossible to dry the tip of a wet shoe by mere exposure to the air in a room. It is necessary to cause a forced circulation of air into and out of the wet shoe in order to effectively and quickly dry the tip of a shoe. While it may be possible to dry the tip of a shoe by a forced circulation of cold air or by the production of a vacuum, I have found that the best effect is produced when the air is heated. It takes less than two minutes to dry a wet shoe when using the device herein disclosed.
The flared and constricted outlet of the attachment is also, desirable for drying moist hair on the head of a person because of the large area upon which the air may blow from the flared outlet. The flared outlet also eliminates a great deal of the excessive motions of the arm of the user usually made when using an electric air blower having the usual non-flared tubular outlet.
It is to be noted that I may provide a plurality of holes 24 and 25 in the bottom and rear of the shoe-shaped attachment so as to dry the sole and rear surfaces of the shoe simultaneously with the drying "of the'tip.
I claim as my invention:
1. A portable shoe drying attachment having a linear bottom substantially coextensive'with' the sole of a, shoe and being designed forv insertion into an upright shoe whilesupportinganair blower at its upper end, comprising ,a curved tubular body forming substantially a right angle, said body having a constricted outlet extending into the shoe to the tipand being defined by upper and lower walls, said'walls being-slightly tion into an upright shoe while supporting an air blower at its upper end, comprising a curved tubular body, said body having a constricted outlet extending into the shoe to the tip and being defined by up r and lower walls, said walls being slightly spaced apart, the lower wall extending outwardly more than the upper wall, the upper wall being curved all along its length into said tubular body and forming a channel permitting outward flow ofiair enteringmsaid shoe .through said body, the :apex of said' lower wall' being upwardly curved and facing said channel, and said attachment having apertures in the bottom and 'rear surfaces thereof for drying the sole and the 'rearlinners surfaces of the shoe.
