Abstract
689,539. Pressure gauges. GRATZMULLER, J. L. June 27,1951 [July 4, 1950], No. 15272/51. Class 106 (ii). A fluid-pressure indicator comprises a casing 1 with end faces 2, 3 of which at least one is removable, a stationary cylinder 7 for a piston 14, the cylinder being on one end face 2 and the piston being subjected to the fluid pressure, a centrally apertured reference member 10 integral with the other end face 3, a bored movable index member 9 slidably mounted on the cylinder 7 and passing through the aperture in the reference member 10, the movable index member having two axially spaced bearing areas 21, means 15 transmitting the movement of the piston 14 to the movable index member 9, removable abutment means 4 between the removable end face and the corresponding end of the casing and elastic means 12 interposed between the reference member 10 and the movable index member 9 to act upon the latter against the action of the fluid pressure. As shown, both the end members 2, 3 are removable, each being pressed outwardly against removable abutment means 4 comprising piano wire sprung into grooves in the casing 1. Fluid pressure fed through a union 6 causes the piston 14 to thrust against the movable index member 9 through an intermediate rod 15 and balls 18, this thrust causing the movable index member 9 to move outwardly through the reference member 10 in a manner compressing the spring means 12. The movable index member 9 has a number of variously coloured rings 24a, 24b, 24c on its outer end, these rings appearing successively as the applied fluid pressure increases. Washers 27 may be interposed under the coloured rings for adjusting the pressure scale of the gauge or to take up mounting inaccuracies. Graduations may be made on the outer end of the slidable member 9 to give an accurate measure of the pressure being gauged. To prevent the piston 14 from being expelled from the cylinder 7 when no pressure fluid is fed into the latter, a drilled plug 30 is forced into the union 6. The gauge may be secured at any desired point by means such as an omega stirrup 31.
