The ‘Crocker Pen Company’ was founded in 1902 in Boston, Massachusetts, by Seth Sears Crocker, Seth Chilton Corker’s father and founder of the well known ‘Chilton Pen Company.
The ‘Crocker Pen’ was a small company which made excellent fountain pens of ebonite with a peculiar filling system : the ‘blow filler system’ (Mooney – another American brand founded by Frank H. Mooney, first settled up in Chicago and then in Toledo, Ohio- may have been the first to use this singular system). To fill the pen sac you had to blow through a simple hole placed in the end of the barrel, thus pressing the bladder. When you stopped blowing, the air kept inside the barrel went out through the hole, and the ‘suction effect’ made the ink go up the nib towards the inner sac. This kind of pens with this unusual system was also sold with a balloon which was placed at the end of the barrel, so that customers who found ‘blowing’ a little elementary could avoid it …

Along with typical ‘eyedropper’ and ‘blow-filler’, Crocker also manufactured the ‘hatched filler’ pens, whose mechanism was the same as the one invented by Sheaffer but for the hatch, which was located at the end of the barrel.

At the end of the 1920’s, all the patent rights were sold to Nicholas Zaino.

Nowadays, Crocker pens are difficult to find, and big models are certainly scarce. Even though the make did not have the prestige and name of big brands and it is today regarded as second rate, the quality of Croker pens is outstanding, turning them into highly valuable pens for collectors.
