ABSTRACT:
A machine for fastening rail plates to cross-ties, utilizing spikes or the like, and method therefore, is disclosed in the present invention. The preferred apparatus of the present invention teaches a system wherein there is provided a conveyor for conveying a plurality of laterally arranged, aligned ties, a loader for loading a single tie upon a template conveyer, and a positioner for positioning a tie at each station during the pre-plating process. The present invention further includes a template system for securing the cross-tie or tie in place, feeding and positioning the rail-plate in place, feeding, dispensing, and positioning the spikes in place, driving the spikes, and discharging the processed tie, the template system utilizing as a principle motive force the displacement of the template reciprocating drive piston for positioning the template, as well as dispensing the plates. The present invention further is configured to facilitate the installation of threaded spikes or screws, as are utilized in high-speed, concrete and other cross-ties. A drilling station is therefore provided for drilling bores into the tie, along with a separate screwed pre-plating station which includes a template for positioning the tie, a plate dispenser, and an array of racheting mechanisms for engaging and screwing threaded spikes or screws into the bores formed by the drilling station to securely pre-plate each plate on a tie, which may be wood or concrete, traditional or high-speed.
