Abstract
Abstract Track construction for a dry kiln and the like including a pair of spaced-apart axially aligned stationary rails disposed on opposite sides of an access opening in the kiln. A movable rail is mounted on one of the stationary rails for swinging between one position fitted between the stationary rails, and another position overlying the one stationary rail. Such construction enables selective positioning of the movable rail to accommodate either movement of a lumber cart into and out of the kiln, or movement of a door into and out of a position closing and sealing the access opening.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
104 words
Track construction for a dry kiln and the like having an access opening, said track construction in operative condition comprising a pair of elongated spaced-apart stationary rails disposed on opposite sides of said opening and substantially axially aligned with each other, a movable rail, and means mounting said movable rail adjacent said stationary rails for movement between one position interposed between said stationary rails and another position overlying one of said stationary rails, said mounting means including an elongated link interposed between said movable rail and said one stationary rail, and pivot means operatively connecting one end of said link to said movable rail.
Claim 2
Dependent Claim
104 words
Track construction for a dry kiln and the like having an access opening, said track construction in operative condition comprising a pair of elongated spaced-apart stationary rails disposed on opposite sides of said opening and substantially axially aligned with each other, a movable rail, and means mounting said movable rail adjacent said stationary rails for movement between one position interposed between said stationary rails and another position overlying one of said stationary rails, said mounting means including an elongated link interposed between said movable rail and said one stationary rail, and pivot means operatively connecting one end of said link to said movable rail.
Claim 3
Dependent Claim
27 words
The track construction of claim 1, wherein said mounting means further comprises another pivot means operatively connecting the other end of said link to said stationary rail.
Claim 4
Dependent Claim
36 words
The track construction of claim 1 which further comprises lateral restraining means mounted on at least one of said stationary rails for inhibiting lateral movement of said movable rail with such in its said one position.
Claim 5
Dependent Claim
26 words
The track construction of claim 3, wherein said lateral restraining means comprises a pair of spaced-apart elongated fingers joined to opposite sides of said stationary rail.
Claim 6
Dependent Claim
133 words
Track construction for a dry kiln and the like having an access opening, said track construction in operative condition comprising a pair of elongated spaced-apart stationary rails disposed on opposite sides of said opening and substantially axially aligned with each other, a movable rail, and means mounting said movable rail adjacent said stationary rails for movement between one position interposed between said stationary rails and another position overlying one of said stationary rails, said mounting means accommodating adjustment of said movable rail to different attitudes, and said movable rail and at least one of said stationary rails being configured whereby with the movable rail in one attitude it is freely movable into the space between said stationary rails, and with the movable rail in an another attitude movement into such space is inhibited.
Claim 7
Dependent Claim
133 words
Track construction for a dry kiln and the like having an access opening, said track construction in operative condition comprising a pair of elongated spaced-apart stationary rails disposed on opposite sides of said opening and substantially axially aligned with each other, a movable rail, and means mounting said movable rail adjacent said stationary rails for movement between one position interposed between said stationary rails and another position overlying one of said stationary rails, said mounting means accommodating adjustment of said movable rail to different attitudes, and said movable rail and at least one of said stationary rails being configured whereby with the movable rail in one attitude it is freely movable into the space between said stationary rails, and with the movable rail in an another attitude movement into such space is inhibited.
Claim 8
Dependent Claim
25 words
The track construction of claim 5, wherein said mounting means comprises means interposed between and operatively interconnecting said movable rail and said one stationary rail.
Claim 9
Dependent Claim
70 words
The track construction of claim 5, wherein the end of one of said stationary rails which faces the other stationary rail is defined by a face whose lower margin is spaced toward the other stationary rail from its upper margin, and said movable rail has an end constructed to fit in matching complementary relation adjacent said end of said stationary rail with said movable rail in its said one attitude.
Claim 10
Dependent Claim
12 words
The track construction of claim 7, wherein said face is substantially planar.
Claim 11
Dependent Claim
92 words
Construction for a dry kiln and the like having an access opening, said track construction in operative condition comprising a pair of elongated spaced-apart stationary rails disposed on opposite sides of said opening and substantially axially aligned with each other, a movable rail, and means interconnecting said movable rail and one of said stationary rails including a pair of side-by-side disposed laterally spaced substantially parallel elongated links, and pivot means for each set of adjacent ends of said links operatively connecting such set of ends to one of said two interconnected rails.
Claim 12
Dependent Claim
92 words
Construction for a dry kiln and the like having an access opening, said track construction in operative condition comprising a pair of elongated spaced-apart stationary rails disposed on opposite sides of said opening and substantially axially aligned with each other, a movable rail, and means interconnecting said movable rail and one of said stationary rails including a pair of side-by-side disposed laterally spaced substantially parallel elongated links, and pivot means for each set of adjacent ends of said links operatively connecting such set of ends to one of said two interconnected rails.
