Here’s an update on our simplex time recorder repair. I have completed the disassembly, cleaning, and reassembly of the time recorder mechanism in what’s turned out to be a rather complex Simplex punch clock. Prior to disassembling, I cleaned the recorder with a degreasing agent to remove most of the heavy grease and dirt. This revealed the details of the smaller parts often hidden under years of built up grime.
I was unable to find any literature on this time recorder mechanism on the web. These mechanisms are quite unique and very complex. There were many variations manufactured, so I had no references available if I ran into difficulties on the reassembly. Therefore, I photographed (as well as taking some video) every step of the disassembly process.
I prefer to reassemble a complex item such as this whilst the disassembly is still fresh in my mind. As such, I tend to approach these jobs with a somewhat fanatical attitude. My goal is to work on it continuously until completion, much to the chagrin of my dear wife. I started the project on a Friday and finished it by Sunday afternoon. It was a marathon operation!
All the rust was removed, the cast-iron frame was repainted and all the bright-work polished.
The reassembly went well, thanks to my meticulous photo / video documentation. As you can see from the before / after photos, the project was well worth the work.
The actual clock movement looked to have had the winding arbor bushings replaced and the entire movement was spotlessly clean. I had little to do to it other than oiling and a quick tune up to get the clock in beat.
As with many time recorders, the connecting rode that connects the movement to the time recording device was missing. I had a spare one, but it was shorter than the one needed for this clock. I cut it in two and used a brass sleeve soldered into place to extend its length.
The case was polished and the movement and recording mechanism were refitted into the case. The dial is still at the ‘Dial House’ pending restoration.
