Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
157 words
For use in a track press of the type adapted to receive a track chain having pins and bushings and present the chain to a movable tool head for removing or inserting the pins and bushings during disassembly or assembly, a multi-pitch tool bar adapted to be mounted on said head for receiving pin and bushing tool holding bolts whereby the pin and bushing tools are positioned to engage the chain pins and bushings, said bar including means for receiving a tool bar mounting bolt for securing the bar to the tool head at at least two heights, a plurality of pairs of spaced threaded holes for receiving the pin and bushing tool holding bolts formed in said tool bar, each pair of spaced threaded holes having a centerline, and at least two pairs of threaded holes disposed on different parallel spaced centerlines whereby the height of the tools as well as the pitch can be selected.
