Abstract

1,136,868. Pneumatic springs. GENERAL MOTORS CORP. 1 June, 1967 [3 June, 1966], No. 25375/67. Heading F2S. [Also in Divisions D1 and H1] A washing machine (Division D1) has a tub 24 (not shown) rotatable by a drive shaft which, when the tub is unbalanced, initiates the movement of the actuator arm 68 of a switch (62), Fig. 2 (not shown), which movement is controlled by a delay mechanism 80. Mechanism 80 comprises a housing 84, mounted on an arm 82 connected to microswitch (62), having a channelsection flange 86 holding a valve plate 88 with a central opening 90. A bellows 94 has an annular flange 92, seated against plate 88 to form a chamber 100, and an elongated tip 96 held in an opening 98 in arm 68. A flexible check valve element having openings 108 off-set from opening 90 is seated against the opposite side of plate 88 and is held by an annular plate 110 seated in flange 86 against the edge of a diaphragm 116 with which it forms a chamber 120. Thus, when arm 68 is moved towards arm 82 air is forced into chamber 120 and diaphragm 116 is expanded, the resistance of diaphragm 116 causing damping of the movement so that momentary movement of arm 68 does not actuate switch 62. Air will return only slowly from space 100 to chamber 120 so that, when switch 62 has been actuated it remains so for sufficient time.
