412,952 Oct. 15, 1889 Tap and holder therefor Charles Elterich New York, NY From 1889-11-28 "The Iron Age":
Charles Elterich, 191 and 193 Worth street, New York, is putting on the market a short... This tap is without the usual shank and constructed so that when held in the wrench or tapping-chuck the thread projects the same length as the regular tap with shank. These taps can also be used from either end, so as to make taper and bottoming tap or plug and bottoming tap. It is also pointed out that this short tap is stronger than the regular tap with shank, and that being shorter it can be more uniformly hardened and tempered and remain straighter, thus securing better quality and economy. In addition to these advantages it is pointed out that these taps can be sold at a lower price than the regular style, and this fact, combined with the advantages above referred to, is regarded as security them a most favorable reception. They are covered by a patent, October 15, 1889. The wrench is described as made of the best material of well-tempered steel and strongly constructed. It will hold all taps from numbers 1 to 14, inclusive... besides its adaptability for holding the short taps... it is also useful for holding broken taps of sufficient length..."
In a 1909 article the inventor, who was still in business at age 70 and had several patents to his credit, mentions these shankless taps as "the best and strongest taps ever made. Unfortunately there is little sale for these taps as customers will not pay the same price for what they call 'half a tap' as they do for a whole one..." See the link for this 1909 article.
