Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 181 words
A machine for working on track rail fastening elements and mounted for mobility on the track in the direction of track elongation, comprising 1. a tool carriage, 2. a tool for working on the rail fastening elements, the tool being vertically adjustably mounted on the carriage, 3. a tool holder wherein the tool is mounted, 4. a guide for the toolholder mounted on the carriage, a. the toolholder and guide cooperating to maintain the tool at a distance from an associated one of the track rails which is secured by the track rail fastening elements on which the tool is to work, 5. an elastically yielding bearing means interconnecting the toolholder and the guide for permitting resilient movement of the toolholder in respect of the guide at least in a direction transverse to the direction of track elongation, and 6. means on the tool for engaging a selected one of the rail fastening elements upon vertical adjustment of the tool into contact with the selected rail fastening element, the engagement automatically centering the tool in respect of the selected fastening element.
Claim 2
Dependent Claim 181 words
A machine for working on track rail fastening elements and mounted for mobility on the track in the direction of track elongation, comprising 1. a tool carriage, 2. a tool for working on the rail fastening elements, the tool being vertically adjustably mounted on the carriage, 3. a tool holder wherein the tool is mounted, 4. a guide for the toolholder mounted on the carriage, a. the toolholder and guide cooperating to maintain the tool at a distance from an associated one of the track rails which is secured by the track rail fastening elements on which the tool is to work, 5. an elastically yielding bearing means interconnecting the toolholder and the guide for permitting resilient movement of the toolholder in respect of the guide at least in a direction transverse to the direction of track elongation, and 6. means on the tool for engaging a selected one of the rail fastening elements upon vertical adjustment of the tool into contact with the selected rail fastening element, the engagement automatically centering the tool in respect of the selected fastening element.
Claim 3
Dependent Claim 18 words
