The hooded nib was not strictly an aesthetic declaration. It allowed for an interior ink reservoir (the "collector") is found really nearby the nib. Imagine if you took a pen with a sizable nib and feed then enclosed all nevertheless tip of the nib inside the pen human anatomy. The fin area of the feed could today be filled up with ink and it won't evaporate. That's a crude approximation of what is taking place because of the 51. Considering that the 51 was initially designed for usage with a fast-drying ink, the matter of evaporation ended up being particularly crucial.
Another innovation had been the slide limit (in other words., the limit don't have to be screwed and unscrewed). Fountain pencils was in fact fashioned with slip caps before, although not using the secure finishing device that Parker developed when it comes to "51." This pen might be uncapped right away, but there was clearly no danger of the cap stopping accidentally.
The least innovative facet of the 51 (about originally) had been its filling system: Parker re-used the device from their Vacumatic fountain pen. In 1948, they retired the vacumatic system and replaced it when you look at the 51 with all the Aero-metric filler. The Aero-metric filler resembles a simple squeeze filler (believe Pilot CON-20), but incorporates a breather tube to make certain that ink is adopted faster than it really is expelled when filling. The sac is mainly enclosed within a protective steel sheath and is squeezed by pushing entirely on a bar that operates across the length of the sac.
The completing system is among the primary issueswill want to think about when buying a "51." For easier filling, i will suggest the Aero-metric, however, if a very big ink capacity is very important for your requirements, you might choose a vacumatic.
Just like its predecessor, the Vacumatic, the 51 was manufactured in and endless choice of types, which changed throughout the lifespan of design. Your body shade, the cap design and product, therefore the video design all diverse notably. In each instance, naturally, unusual variations will demand greater rates. This is especially true of colors with a high gathering caché, including plum, burgundy, or Nassau green.
Unlike the Vacumatic, the 51 had not been available in many sizes. In reality, it had been originally only for sale in one dimensions, but a smaller "demi" design ended up being introduced in 1947. If you are not purchasing the pen face-to-face, it certainly is best to get exact measurements from the vendor.
If you are purchasing an "ordinary" pen as a user in place of a collector, you can expect to spend about $90-160 US.
Filling the vacumatic 51 is basically exactly like completing a Parker Vacumatic, however with one included wrinkle. The blend associated with enthusiast behind the nib as well as the small orifice across the feed implies that there was a good chance that after you disappear from the ink container with your filled pen, you're moving a trembling fall of ink just waiting to trickle on your clothes or make a huge mess on page when you begin to create. One method to stay away from that is to get rid of the pen through the ink bottle utilizing the plunger in the down position. After that, once you release the plunger, any ink in the feed area will undoubtedly be drawn safely in to the collector. Alternatively, only give the tip associated with pen a beneficial wipe with a paper towel when you completing.
