I reserve the right, however, to employ the `mechanism herein described on'other types of scales.

In assembling the parts of a scale of this 'type it has been found to be extremely difficult to counterbalance the weight of the hand and to counterbalance the weight ofthe link, because the adjustment of the cou'nterbalance of one of these parte: destroys the accu'- racy of the counterbalance" of the other. e Hence experience has proved it advisabley to adjust these counterbalances separately, as described below. Furthermore, 'after' the scale is set up ready for'use and with the.

hand standing accurately on the zero-line when the pendulum is perpendicular ity is often found on testing the scale that the hand does not accuratelyl register with all the inedge ofthemain pivot 7.

Vention consists in details of construction' dicating-lines onth'e table. Thisis due to the fact that the extremes ofv movement of the link-pivot arejnot-in` proper relation tor a horizontal line drawnthrough the active The' present indescribed Abelow in connection with a scale of the type illustrated herein 'and set "forth, 4vabove,r wherebythe difficulties just menl tioned can be 'overcome quickly, easily, ac` ourately, and permanently at the time 'fthe parts are assembled.v

tion to which the hand moves. If the-move` vand such test isveffected by placing a known*v i Yweight on the platform and'noting thepovsiment is excessive, it indicates that` the path of the link-pivot is too high relative tothe main pivot, and if themovement of the'hand is not sufficient it indicates that the pathV of the link-pivot" is too low. To correct either ofv these inaccuracies, oneof the screws'970 and 971 is loosened, while the other is tightened, which operation obviously rocks the link-carrier slightly over the hub, andhence changes the relative position of the active edges of' the link-pivot and the main pivot,.

The presentspecic'ation and drawings describe and illustrate' only the manner I prefer atl-.this time for carrying outv the Ageneral idea.
