Description:
The patent comprises the tubular core with external grooves, the band wire with its hooked ends that face each other, and the "pliers" type tool for manipulating the wire.

The specifications note general awareness of other wire and band type hose clamps, and differentiate this form from them.

The pliers tool received patent no. 445,834 on Feb. 3, 1891.

The metal band is the primary focus of Canadian patent CA-30,988 granted March 22, 1889, although the tool and tubular coupling are also mentioned in the claims and shown in the drawings.

The pliers tool (with patent date Feb. 3, 1891), tubular core and wire (with patent date May 7, 1889) are shown in 1890s ads from C. E. Hudson & Co. Leominster, Mass.
