These are called "SILENT PRECANCELS" which include a group of lines, bars, rules, letters, "ticket punches" and designs as illustrated in David W. Smith's 210 page, spiral bound, 95%+ color illustrated book on the subject he published in 2016, with "off-" and "on-cover" catalog prices.
The subject of "Silent Precancels" is difficult and complex, only because many appear the same. Many times, identify a "Silent" correctly, you need to place your stamp next to the image, to get an exact match; for lines and rules you may have multiple city, state matches.
I spent eight (8) hours over three afternoons with a very close friend, who is an advanced precancel specialist, trying to identify his "Silents." We BOTH had problems correctly identifying what we thought were simple "silent cancels" -- were we wrong about that one. So, I'm giving you my best "guesstimate" on this one. So, PLEASE, NO ROCKS, STONES or used stamp hinges if I'm in error.
Here are my best guesses:
TOP LINE//Upper Right Hand Corner (#1) :

So again, the above are my best guesses. PLEASE, slings & arrows if in error. Without placing "silents" side-by-side against established images, it is impossible to accurately identify what you have.
