Abstract

13,749. Simmance, J. F., and Abady, J. June 7. Barometers. - Relates to barometers and pressure gauges of the type employing an elastic chamber or Bourdon tube, and consists in the means for. transmitting the movements of the chamber &c. to the spindle carrying the pointer or recording-pen so as to obtain equal movements of the pointer for equal changes in pressure. A method of mounting the pointer on its spindle and means for varying the position of this spindle so as to adjust for zero, are also described. The elastic chamber 1 is connected by a link 4 to a crank-arm 6 attached to the pointer spindle 10. The link and the crank are both adjustable as to length, and the crank is provided with a movable weight 9. The pointer is carried by a ring 24 pivotally supported on the spindle 10, Figs. 3 and 5, and provided with a screwed rod 27 carrying a weight 28. By moving this weight, the distance between the extremity of the pointer and the axle may be varied. The spindle 10 is rotatably mounted in the arms of levers 14, which may be shifted in position by operating a milled head 19 so as to adjust the pointer exactly to zero.
