Abstract

898,381. Dynamometers. HAMILTON, T. W. Jan. 18, 1961 [Jan. 28, 1960], No. 3151/60. Class 106 (2). [Also in Group XVIII] A pneumatic pressure transmissing device comprises a chamber with inlet means for admitting air under a pressure greater than that to be transmitted, an outlet duct in communication with the inlet and downstream thereof and a pneumatic pressure relief opening closed by a loose cover which is acted on by a damper to prevent it from vibrating and which is also acted on by a variable force, e.g. from a weighing machine (see Group XVIII), applied as a thrust along a line of action in alignment with the resultant of the pneumatic pressure in the chamber acting on the cover. When a valve 6 is opened air under pressure, from a source 5, is admitted to the pressure chamber 1 until the downward force is overcome and the cover 11 lifts, allowing air to escape between an annular projection 13, on the cover, and its seating 13a. The movement of the cover is damped by a disc 14 connected by a bolt 15 to the cover and submerged in oil in the bottom of the chamber. When there is equilibrium between the pressure and the downward thrust the valve 6 is closed gradually until the flow through the chamber is very small, under which condition the pressure in the outlet pipe 8 equals that in the chamber 1 and is in linear relation to the variable applied force. The pressure is shown by a gauge 9, calibrated to read directly in force measurement units. Alternatively, the cover 11 may be below the chamber 1, resting on the pivot point 19, its recess 12 forming the main part of the chamber.
