Appliance For Uniting and Repairing Rubber Hose Patentee: Charles E. Hudson - Leominster MA Granted:1889-05-07

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.

US Patent: 3,384

Bench-vise Patentee: Jeremiah Peck - Waterbury CT Granted:1843-12-20

A writeup on this patent in the August 1848 Journal of the Franklin Institute gave credit to "Mr. J. Peck, and Mr. L. Pardee, of New Haven". Pardee was presumably Leonard Pardee, a joiner in New Haven at the time, who became a successful carriage maker. We speculate that Pardee was responsible for integrating the treadle mechanism to operate the vise, which improved on the handwheel in Peck's patent A. D. Jones' Gazetteer for Connecticut for 1857-8 lists Jeremiah Peck as a machinist in New Haven. There was a planing mill, L. Pardee & Co., in New Haven. A classified ad in the 1848-11-11 Scientific American: " PECK'S PATENT VISE WITH FOOT LEVER. THIS Vise is worked entirely by the foot and is admitted by all who have used them to be the best and, strength, saving of time and convenience considered, the cheapest Vise in use. For sale by QUINCY & DELAPIERRE, 71 John st. New York; Geo H. Gray & Co., Boston; Curtis & Hand, Philadelphia; Way & Brothers, Hartford, Ct.; and by the proprietor. J. S. GRIFFING, New Haven, Ct."
