Parcel scales

 pendulum parcel scale by Marion & co, England. The mechanism fits Hiscock´s patent:

"A vertical rod is pin-jointed to three parallel forked levers, one above the other, the uppermost arm projecting beyond its axis, and having a counter-weight fitted. The arm is bent in such a manner as to allow the weight to pass under the lower of the three axes. The second forked arm carries a toothed segment geared with a wheel attached to a pointer which travels around a graduation dial indicating weight. A second pointer, traveling over a quadrant on the same dial, indicates rates of postage. A spring buffer is attached to the baseplate to check the motion of the weight on its return swing."
