Abstract
Abstract Apparatus for preparing the junction of two rails on a railroad right-of-way for application of a bonded rail joint or a welded joint. The apparatus includes a frame mounting flanged wheels for movement along a railroad right-of-way and a vertically movable carrier mounting opposed pairs of rotary abrading devices which are adapted to abrade and clean the underside of the head of the rail, the web and the upper surface of the foot of the rail. A vehicle defined by the frame also includes a source of bottled gas for fueling a burner customarily used in the process of applying bonded rail joints as well as an auxiliary abrading device for use in deburring rail ends, etc.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
164 words
Apparatus for preparing the junction of two rails on a railroad right-of-way for application of a bonded rail joint or a welded joint comprising: a frame adapted to be moved along a railroad right-of-way; carrier means mounted on said frame for vertical movement thereon; means for moving said carrier means vertically on said frame; means for selectively adjusting the lowermost position of said carrier means on said frame; at least a pair of opposed abrading means, each adapted to abrade a respective side of a rail, secured to said carrier means for movement therewith; and means for selectively moving the abrading means of said pair towards and away from each other in a generally horizontal direction whereby said carrier means may be vertically moved to selectively position said abrading means at a desired position adjacent an underlying rail on a railroad rightof-way and whereby said abrading means moving means can be selectively operated to clear the head of a rail on a railroad right-of-way.
Claim 2
Dependent Claim
164 words
Apparatus for preparing the junction of two rails on a railroad right-of-way for application of a bonded rail joint or a welded joint comprising: a frame adapted to be moved along a railroad right-of-way; carrier means mounted on said frame for vertical movement thereon; means for moving said carrier means vertically on said frame; means for selectively adjusting the lowermost position of said carrier means on said frame; at least a pair of opposed abrading means, each adapted to abrade a respective side of a rail, secured to said carrier means for movement therewith; and means for selectively moving the abrading means of said pair towards and away from each other in a generally horizontal direction whereby said carrier means may be vertically moved to selectively position said abrading means at a desired position adjacent an underlying rail on a railroad rightof-way and whereby said abrading means moving means can be selectively operated to clear the head of a rail on a railroad right-of-way.
Claim 3
Dependent Claim
61 words
Apparatus according to claim 1 wherein two said pairs of said abrading means are mounted on said carrier means, two of said abrading means being configured and structured to abrade a portion of the web and the foot of a rail, the other two of said abrading means being configured to abrade the web of a rail adjacent the head thereof.
Claim 4
Dependent Claim
24 words
Apparatus according to claim 2 wherein each said abrading means comprises a rotatable member mounting a plurality of generally radially extending, flexible, abrading flaps.
Claim 5
Dependent Claim
90 words
Apparatus according to claim 3 wherein each of said abrading means is rotated by a hydraulic motor, each of said hydraulic motors being mounted on one end of an elongated member, the opposite end of each said elongated member being pivotally connected to said carrier means for rotation about a generally horizontal axis; and wherein said abrading means moving means comprises a hydraulic cylinder having opposed extendable elements interposed between the elongated members of each said pair of abrading means; and means providing a source of hydraulic fluid under pressure.
Claim 6
Dependent Claim
58 words
Apparatus according to claim 1 further including means on said frame for mounting a bottled gas canister; said apparatus further including a flexible gas conduit adapted to be associated with a bottled gas canister, and elongated, opposed burner means associated with said conduit and adapted to be disposed on opposite sides of a rail for heating the same.
Claim 7
Dependent Claim
135 words
Apparatus according to claim 1 wherein said frame includes a pair of upstanding members generally aligned with a pair of said wheels adapted to engage the same rail of a railroad right-of-way, and wherein said carrier means includes a cross member interposed between said upstanding members and slidably movable thereon, said abrading means comprising a pair of opposed rotatable members, each driven by a respective motor, and a pair of elongated members each having one end secured to a respective one of said motors and the opposite end pivotally secured to said carrier means; and wherein said abrading means moving means includes two extendable elements mounted on said carrier means and interposed between said elongated members and operable to engage the same to rotate each elongated member about its pivotal connection to said carrier means.
Claim 8
Dependent Claim
119 words
Apparatus according to claim 6 wherein each of said abrading means includes a rotatable hub and a plurality of generally radially extending flaps provided with an abrasive surface mounted thereon for rotation therewith, one of said abrading means being generally cylindrical in configuration and adapted to abrade the web of the rail adjacent the head thereof, the other of said abrading means being configured generally as a pair of opposed frusto-conical surfaces, one of said surfaces being angled so as to engage substantially tHe entirety of the upper surface of a foot of a rail, the other of said surfaces being angled so as to engage substantially the part of a rail flange adjacent the foot of a rail.
Claim 9
Dependent Claim
90 words
Apparatus according to claim 7 wherein two of said pair of abrading means are provided, the cylindrical ones of said abrading means in each pair being located on opposite sides of a rail and the frusto-conical ones of said abrading means in each pair being located on opposite sides of a rail and wherein said motor means for each of said abrading means drive each of said abrading means in directions effective to offset frictional forces tending to move said frame along the railroad right-of-way on which it may travel.
Claim 10
Dependent Claim
57 words
Apparatus according to claim 2 further including a boom substantially universally-connected to said frame; and auxiliary abrading means secured to said boom for movement therewith; means for adjusting the attitude of said auxiliary abrading means with respect to said boom; and means for adjusting the angular relation of said auxiliary abrading means with respect to said boom.
Claim 11
Dependent Claim
35 words
Apparatus according to claim 9 wherein said auxiliary abrading means includes a rotary abrading wheel, means for rotating said abrading wheel, a guide wheel, and means for biasing said guide wheel toward said abrading wheel.
