The patent was issued in 1858 to Blaney E. Sampson, was re-issued in 1860, and was, in 18T2, extended for seven years. It eontained two claims — First, an open jaw for coupling a street-car pôle to the car; and, second, a method of supporting a street-car pôle 80 as to take the weight of the pôle ofif the horses' necks. The plaintiflf testified that he had an established license fee of $10 a car for the use of the open jaw covered by the first claim alone, and a license fee of $50 for the use of the devices included in both claims ; but that he had never coUected any license fee for the use of the pole-support device alone, cov- ered by the second claim. �Evidence was given by the defendants of prier use of the devices included in both claims, in New York, Jersey City, Troy, and other places; and of the device covered by the first claim, in Philadelphia. Eebutting testimony was given by the plaintiff as to the prior use of the device covered by the second claim, but not as to the prior use of the device covered by the first claim. �After the evidence was in, the plaintiff's counsel stated to the jury that he abandoned the first claim. �*Reported by Frank P.
