Wotapek Injector, Patent Model

Description
This model was submitted to the U.S. Patent Office with the application for the patent issued to Joseph Wotapek, of New York, New York, May 6, 1884, no. 298329; assigned to the Nation Manufacturing Co.
The improvement involved in this injector is the use of a nozzle holder by which the scale-incrusted nozzle or tube of the injector may be easily removed to permit cleaning. The holder is threaded into the shell of the injector from which it and the tube are drawn by unscrewing the bolder. The holder turns independently of the tube so that the tube itself is not subjected to torsion when being withdrawn from the shell.
