From the Smithsonian Collection

William A. Clark of New Haven, Connecticut, received a patent for an auger to bore holes in ice, and this is the model Clark submitted with his patent application. His design added a small threaded point to the leading end of a standard, helical drilling bit. The point would cut a pilot hole into the ice, and its threaded sides would grip the ice, pulling and guiding the entire auger forward.

Physical Description

Clark's auger is a 5.5 inches long by 1 inch in diameter. It is made of steel.

History

"I have found by experiment that when an attempt is made to bore into ice with the ordinary gimlet or screw-point," William Clark wrote in his patent specification, "the point will not take hold on the ice, the screw simply fracturing and breaking away the ice around it so that the screw can get no hold in it." His "Improved Tool for Boring in Ice" aimed to solve this problem with its threaded leading point, which would grip the ice and hold the auger's "cutting-lips firmly to their work."

Clark described his improved auger as especially useful for fishermen in winter, when holes might be needed for running lines or for the insertion of explosive charges to break up the ice, "as is sometimes necessary in cases of an ice-gorge in streams or rivers."
