Abstract
Abstract A vertical hollow tube closed at its top end has a first hole in its side wall adjacent its top end and is filled with gaseous deodorizer under pressure. A vertical hollow cylinder closed at its top end and open at its bottom end has a second hole in its side wall. The cylinder is vertically slidable up and down along the tube whereby the holes can be moved into and out of alignment. The deodorizer escapes from the tube to the outside through the holes when aligned and is otherwise confined within the tube. Spring means disposed within the cylinder between the top ends of cylinder and tube normally biases the cylinder in a position relative to the tube at which the second hole is out of alignment with and disposed above the first hole. When a shoe engages cylinder and tube with the cylinder disposed' inside the toe, the weight of the shoe overcomes the normal bias and the cylinder is moved downward until the second hole is out of alignment with and disposed below the first hole.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
229 words
A combined shoe tree and shoe deodorizer comprising: at least one vertical tube closed at its top end and having a first hole in the side wall adjacent the top end, said tube being filled with gaseous deodorizer under pressure; a hollow vertical cylinder having a second hole in its side wall, the cylinder having a closed top end and an open lower end, the top end of the tube extending axially into the cylinder through the lower open end thereof, said cylinder being vertically slidable upwardly and downwardly with respect to the tube, whereby said holes can be moved into and out of alignment, said deodorizer escaping from the tube interior to the outside through the holes, when aligned and otherwise being confined within the tube; and spring means disposed within the cylinder between the top end of the cylinder and the top end of the tube, said means normally biasing the cylinder in a position relative to the tube at which the second hole is out of alignment with and disposed above the first hole, said cylinder, when a shoe engages the cylinder and tube in such manner that the cylinder is disposed within the toe of the shoe, being moved downward because the weight of the shoe overcomes the normal bias until the second hole is out of alignment with and disposed below the first hole.
Claim 2
Dependent Claim
229 words
A combined shoe tree and shoe deodorizer comprising: at least one vertical tube closed at its top end and having a first hole in the side wall adjacent the top end, said tube being filled with gaseous deodorizer under pressure; a hollow vertical cylinder having a second hole in its side wall, the cylinder having a closed top end and an open lower end, the top end of the tube extending axially into the cylinder through the lower open end thereof, said cylinder being vertically slidable upwardly and downwardly with respect to the tube, whereby said holes can be moved into and out of alignment, said deodorizer escaping from the tube interior to the outside through the holes, when aligned and otherwise being confined within the tube; and spring means disposed within the cylinder between the top end of the cylinder and the top end of the tube, said means normally biasing the cylinder in a position relative to the tube at which the second hole is out of alignment with and disposed above the first hole, said cylinder, when a shoe engages the cylinder and tube in such manner that the cylinder is disposed within the toe of the shoe, being moved downward because the weight of the shoe overcomes the normal bias until the second hole is out of alignment with and disposed below the first hole.
Claim 3
Dependent Claim
20 words
The deodorizer of claim 1 further including sealing means disposed between cylinder and tube to prevent leakage of said deodorizer.
Claim 4
Dependent Claim
33 words
The deodorizer of claim 2 further including means disposed partially on the tube and partially on the cylinder to prevent said cylinder from sliding off the tube in the absence of said shoe.
Claim 5
Dependent Claim
47 words
The deodorizer of claim 3 including a horizontal tube open at both ends and secured at one end to the bottom end of the tube, said tube bottom end being open and means to supply said deodorizer under pressure to the opposite end of the horizontal tube.
