Abstract
913,755. Measuring electrically. NEW YORK AIR BRAKE CO. July 25, 1960, No. 25808/60. Class 40 (1). [Also in Group XIX] Indicating apparatus controlled by impulses from a remote location comprises a pointer 132 positioned back and forth by a member 90 which is driven in opposite directions between two stops by separate driving arms 70, 80, either of which can be connected or disconnected from a common constant speed driving motor 120. The motor 120 drives two discs with peripheral teeth 57, 55, at the same speed but in opposite directions about the axis of a shaft 50, to which is fixed a plate 68 with a forked extension engaging a fixed spacer to prevent the shaft 50 rotating. The shaft 50 is slidable in an axial direction and when urged to the right by a spring 110, as shown in Fig. 3, the plate 68 sandwiches two wheels 74 on the arm 70 between itself and the disc with teeth 57 so that this disc drives the arm 70 from one stop into contact with the member 90 which it pushes towards the other stop. When a solenoid 100 is energized its armature 102 presses against a stronger spring 112 to overcome the spring 110 and displace the shaft 50 so that the plate 68 releases the arm 70 which is spring-returned to its initial stop and sandwiches two wheels 84 on the arm 80 between itself and the disc with teeth 55 so that this disc drives arm 80 from the second stop toward the opposite side of the member 90 which it pushes towards the first stop. The member 90 is secured to a gear-wheel 92 meshing with a sector 142 on the shaft 140 of the pointer 132. A leaf-spring 94 bearing on a fixed plate 96 acts as a brake to hold the member 90 and pointer 132 in set position. The apparatus is described as the receiver in a telemetering system wherein at the remote station another motor operating in synchronizm with the motor 120 drives a cam co-operating with a measuring instrument to close a circuit, including the solenoid 120 for a part of each cycle proportional to the value of the quantity being measured. In this way the pointer 132 indicates the value of the measured quantity against an appropriate scale.
