Axial Telegraph: The figure "represents a form of telegraph in which axial force is used [to print the dots and dashes on the paper strip]. This is introduced as a new instrument, and its originality is here claimed. Two upright coils ... are supported a short distance above the baseboard. Entering these from above is a U-shaped rod of soft iron, fitted to be drawn up into the coils, under the influence of the galvanic current." from the 1851 Manual of Magnetism, pg 202; in the appendix to the 1842 edition)

This apparatus is at Middlebury College. It was being sold as late as 1889 by Queen of Philadelphia for $7.00.

Telegraph, with Clock-Work. The electro-magnet and paper reel are the same as the telegraph above, but a clockwork mechanism has been added to draw the paper along. 

   The cost was $25.00 to $35.00 in the 1851 edition of the Manual of Magnetism.

   The instrument is in the Smithsonian Institution collection.

   There is no maker's mark on this apparatus, but it clearly is Davis-style apparatus. It is probably by Hall or Palmer and Hall, Daniel Davis' successor companies. 

   The clock-work paper drive telegraph is at Wesleyan University in Middletown, Connecticut.
