A one-page patent abstract from Engineering, 31 August 1900, describing J. Harrison's improved copping motion for spinning frames (patent no. 13,443, dated June 28, 1899, accepted July 18, 1900). It explains a gear train of fixed and loose shafts with large and small pinions and a ratchet wheel that shortens the lifting chain and reduces the lift of the rail after each traverse, without enlarging the pinions. Four mechanical drawings illustrate the gearing.
