Abstract
A pair of spaced apart arms disposed on the side of a railway maintenance machine, the arms extending outwardly and carrying vertically positioned sleeves at their outer ends. Bars are slidably held in the sleeves for mounting of a fabric roll on their upper ends. Extension members extend horizontally from the lower ends of the bars. Idler and tension rollers are rotatably mounted across the arms, and an applicator tube extends diagonally under the machine frame, and beneath track raised by the machine, such that fabric can be continuously unrolled and passed under the tension roller, over the idler roller, over the applicator tube and on the track bed.
Claims15
An undertrack fabric applicator for use on a railway undertrack maintenance machine of the type which raises track above the track bed as it moves along the track, comprising:
- a pair of spaced apart arms connected to one side of the maintenance machine frame immediately behind the track raising portion thereof, the arms extending outwardly from the machine frame,
- a bar connected across the outer end of each arm in a substantially vertical position with respect to the track bed, the bars being adapted for rotatably mounting of a roll of fabric between the arms, with the lower ends of the bars extending below the level of the raised track,
- an extension member connected to the lower end of the bar of each arm and extending outwardly in a substantially horizontal position with respect to the track bed,
- an idler roller connected across the arms from the outer end of one extension member to the other;
- a tension roller connected across the arms below the level of the fabric roll,
- holding means disposed on the side of the maintenance machine opposite that on which the pair of arms are connected, the holding means being positioned and adapted for securing the outer end of an applicator tube extending diagonally under the raised track from one side of the machine frame to the other, and
- a non-rotatable applicator tube running from the outer end of one extension member diagonally under the raised section of track to the holding means on the other side thereof, such that during movement of the maintenance machine on the track the fabric can be continuously unrolled from the fabric roll and passed under the tension roller, over the idler roller, over the applicator tube, under the raised track, and onto the prepared track bed.
An undertrack fabric applicator for use on a railway undertrack maintenance machine of the type which raises track above the track bed as the machine moves along the track, comprising:
- a pair of torque tubes mounted across from one another on either side of the maintenance machine frame, the torque tubes being disposed parallelly to the ground,
- V-shaped arms secured at their closed ends to the end portions of the torque tubes,
- hydraulic means mounted on the maintenance machine frame for applying torque to the torque tubes to effect pivoting of the V-shaped arms from a vertical travel position to an outwardly extending operable position,
- a sleeve member connected substantially perpendicular across the outer ends of the V-shaped arms, such that the sleeves will be in substantially vertical position when the arms have been pivoted to an operable position,
- a bar slidably secured in the sleeves of each arm, the bars being adapted for rotatably mounting of a roll of fabric between the V-shaped arms with the lower ends of the bars extending below the level of the raised track,
- an extension member connected to the lower end of the bar of each V-shaped arm and extending outwardly therefrom in a substantially horizontal position with respect to the track bed,
- a support column mounted near the inner end of the extension member parallel to the bar and being substantially shorter than the bar,
- an adjustment plate mounted on the extension member opposite that bearing the support column,
- a tension roller mounted across the V-shaped arms from the support column of one extension member to the adjustment plate of the other,
- an idler roller running from the outer end of one extension member to the outer end of the other extension member,
- a non-rotatable applicator tube running from the outer end of one extension member diagonally under the railway maintenance machine frame to the outer end of the extension member on the other side thereof, such that during movement of the maintenance machine on the track fabric can be continuously unrolled from a fabric roll and passed under the tension roller, over the idler roller, over the applicator tube, and onto the track bed under the track section temporarily raised above the track bed by the maintenance machine.
