Abstract
322,258. Simmance, J. F. Sept. 10. 1928. Elastic - diaphragm pressure gauges. - The flexible container is supported at its free end by the member through which the movement of the container is transmitted to the pointer spindle in such a manner that the weight of this end of the container exerts only an axial thrust upon the spindle. The container formed by a series of connected aneroid boxes 1 is arranged with the axis horizontal. One end of the container is attached to a fitting 2, both the end and the fitting 2 being supported by a bracket 3 secured to the base 4. The other end of the container 1 is provided with a bushing 5 within which is adjustably secured one end of a rod 6 the other end of which carries a screw 7 the end of which has a conical hole which rests on a pin projecting upward from a crank adjustably mounted on an arm 10 projecting from the spindle 11 of the indicating pointer 16 which is provided with a counterbalance 17 and a bent-over end 18 moving over a part cylindrical scale. A disc 14 slides on the spindle 11 and mav be clamped just above the screw 7 to prevent the latter jumping away from the conical pin. A leaf spring is attached at one end to a support 22 adjustably mounted on the rod 6 the other end engaging a fixed stop 23. The spring exerts an initial pull on the aneroid boxes which pull decreases as they extend until the spring ultimately becomes disengaged from the stop. A uniform scale is thus secured. The frame 13 which carries the spindle 11 may be adjusted by a screw for adjusting the pointer to zero. The bracket 29 serves to mount the instrument on a wall and by adjusting the scale may be made to face in any direction. The scale is of opalescent glass and may be illuminated by a lamp in the casing or by a window in the upper part of the casing and an inclined mirror inside the casing. Several instruments may be mounted vertically above each other in a small space. The Provisional Specification also describes a form in which the container is mounted with the axis vertical, movement being transmitted to a horizontal for the pointer by means of an adjustable rod, a vertical link and an adjustable crank on the spindle.
