Abstract
Abstract An apparatus for drying boots has a hollow housing one of whose upright side walls is formed of a plurality of upper and a plurality of lower pairs of apertures. A blower, a heater, and an ozone generator are provided in this housing for expelling air from these apertures. One aperture of each of the pairs is provided with an upwardly inclined tube having an open upper end. Roots can be racked over these tubes so that air is caused to flow by the apertures of the tubes through the inside of the boots whereas air from the other aperture of the respective pair will flow over the outside of the boot and dry it. In addition at least the upper apertures are associated with a catch trough for drips emanating from the boots on the respective tubes. A larger trough may be provided at the lower apertures for catching drips from the respective boots as well as for catching liquid deflected by the upper troughs against the side of the apparatus.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
170 words
An apparatus for drying boots, said apparatus comprising: a hollow housing having an upright side wall formed with a plurality of upper pairs of apertures and a plurality of lower pairs of apertures; means including a blower in said housing for expelling air from said apertures; a plurality of upwardly inclined tubes each having a lower end secured to said housing over one aperture of a respective pair of said apertures and an upper end formed with an outlet hole, each of said tubes and the respective one aperture being positioned with respect to the other aperture of the respective pair so that when a boot is hung over the tube heated air from the other aperture of the respective pair passes over the boot; and means including an upwardly open trough offset from said housing and extending under said upper pairs of apertures for catching liquid dripping from boots over the respective tubes and for conducting said liquid away from boots on the tubes of the underlying lower apertures.
Claim 2
Independent Claim
170 words
An apparatus for drying boots, said apparatus comprising: a hollow housing having an upright side wall formed with a plurality of upper pairs of apertures and a plurality of lower pairs of apertures; means including a blower in said housing for expelling air from said apertures; a plurality of upwardly inclined tubes each having a lower end secured to said housing over one aperture of a respective pair of said apertures and an upper end formed with an outlet hole, each of said tubes and the respective one aperture being positioned with respect to the other aperture of the respective pair so that when a boot is hung over the tube heated air from the other aperture of the respective pair passes over the boot; and means including an upwardly open trough offset from said housing and extending under said upper pairs of apertures for catching liquid dripping from boots over the respective tubes and for conducting said liquid away from boots on the tubes of the underlying lower apertures.
Claim 3
Dependent Claim
15 words
The apparatus defined in claim 1 wherein each of said tubes is of polygonal section.
Claim 4
Dependent Claim
28 words
The apparatus defined in claim 2 wherein each of said tubes is of substantially rectangular section with an upper side constituted by a family of parallel horizontal lines.
Claim 5
Dependent Claim
26 words
The apparatus defined in claim 1, further comprising means for generating ozone and mixing same with said air prior to expelling of same from said apertures.
Claim 6
Dependent Claim
26 words
The apparatus defined in claim 1 wherein each of said other apertures is directly above the respective one aperture and slightly above the respective upper end.
Claim 7
Dependent Claim
57 words
The apparatus defined in claim 1 wherein each of said tubes has a respective tube axis extending at an angle of between 30° and 60° upwardly from said side wall, each of said tubes being axially closed at the respective upper end and formed thereadjacent with at least one radially opening hole constituting the respective outlet hole.
Claim 8
Dependent Claim
22 words
The apparatus defined in claim 1 wherein said housing is a box and is provided with rollers for displacement along the ground.
Claim 9
Independent Claim
188 words
An apparatus for drying boots, said apparatus comprising: a hollow housing having an upright side wall formed with a plurality of upper pairs of apertures and a plurality of lower pairs of apertures; means including a blower in said housing for expelling air from said apertures; a plurality of upwardly inclined tubes each having a lower end secured to said housing over one aperture of a respective pair of said apertures and an upper end formed with an outlet hole, each of said tubes and the respective one aperture being positioned with respect to the other aperture of the respective pair so that when a boot is hung over the tube heated air from the other aperture of the respective pair passes over the boot; and means including at least one upwardly open trough under said upper pairs of apertures and having a drain opening adjacent said side wall and oriented to directed liquid caught by said trough against said side wall for catching liquid dripping from boots over the respective tubes and for conducting said liquid away from boots on the tubes of the underlying lower apertures.
Claim 10
Independent Claim
188 words
An apparatus for drying boots, said apparatus comprising: a hollow housing having an upright side wall formed with a plurality of upper pairs of apertures and a plurality of lower pairs of apertures; means including a blower in said housing for expelling air from said apertures; a plurality of upwardly inclined tubes each having a lower end secured to said housing over one aperture of a respective pair of said apertures and an upper end formed with an outlet hole, each of said tubes and the respective one aperture being positioned with respect to the other aperture of the respective pair so that when a boot is hung over the tube heated air from the other aperture of the respective pair passes over the boot; and means including at least one upwardly open trough under said upper pairs of apertures and having a drain opening adjacent said side wall and oriented to directed liquid caught by said trough against said side wall for catching liquid dripping from boots over the respective tubes and for conducting said liquid away from boots on the tubes of the underlying lower apertures.
Claim 11
Dependent Claim
35 words
