Becton, Dickinson & Co. Cornwall 2 cc Syringe dating from 1954 to 1970. The patent was filed June 12, 1948, and granted to Henry G. Molinari on July 27, 1954. The patent was assigned to Becton, Dickinson & Co. From the patent claims: "...the assembly should include not alone a glass barrel or cylinder, but also a piston or plunger rod of glass slidable within that barrel. By movement of the latter not alone may medicament be expelled from the barrel for purposes of injection, but also that medicament may be drawn into the cylinder to charge the syringe with a suitable quantity of desired liquid....the barrel is usable with only the particular plunger selected for same....it is a primary object of the invention...[that] these assemblies will have their parts interchangeable so that it will be unnecessary to, for example, identify the barrel and plunger by identical serial numbers." Note that such serial numbers ARE on this syringe.
