Two datestamps were printed in one move by the postal clerk: the first cancelled the postage stamp and the second was a readable proof of date on the cover.
But it came back to service in the 1920s: the second datestamp was replaced by a commercial message inscribed in a round cornered quadrilateral.
Eugène Daguin was amongst the engineers who proposed "stamping machine" projects to the French posts.
[2] Machines described in patents #151332 and #151355 recorded on 30 September 1882, completed three times in 1883, were closer to this sentence than the initial drawing.
The clerk lowered the arm toward the mail: the gesture permitted the inking of the datestamps thank to an upward roll.
A "touching piston"[3] immobilized the piece of mail firmly on the table: a clear postmark could be made in one move and a spring quickly raised the arm upward.
Additions to the patent on 24 October and 4 December 1883 gave a precise description of the machine by Daguin, including the "touching piston".
Between June 1884 and the first years of the 20th century, the Daguin machine was a success in French post offices.
Contracts for Daguin commercial cancellation were ordered not to be renewed and replaced with undulated lines.
In Romania, six post offices possessed a Daguin machine between 1890 and 1904: Brăila, Bucharest, Focşani, Galaţi, Iaşi and Ploieşti.
A postal stationery was issued for the international stamp show Bucharest 2005 picturing Eugène Daguin and his machine.
The oldest text he found was entitled "A philatelic enigma: the strange cancellations of Toulouse on Sage series 'N under U'".
[12] During the 1950s, the topic passionated a growing group of collectors after Louis Goubin published an article about "the problem of the gemini marks in France from 1984 to our days".
[14] In 1992, Émile Barthélémy created the "one-eyed Dagion" (Daguin borgne) when a sole datestamp was used.
The Daguin commercial cancellations made between 1923 and 1957 has been helping the topical stamp collectors of French local subjects.
